Japanese Patent No. 2761282

  By the way, in the drainage system, when switching the flow path, there are a plurality of candidates for the position of the flow path switching member after the switching. For example, when switching the flow path in a state where the flow path switching member is disposed at the first position, the position (second position) at which the second outlet is closed is set as a candidate for the position of the flow path switching member after the switching. And a position for closing the inlet. In such a case, there is a possibility that the flow path switching member may be disposed at a position that closes the inflow port, although the flow path switching member must be disposed at the second position. There was a possibility that the position of the member was mistaken.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a piping member having a main body and a flow path switching member, in which the position of the flow path switching member after switching can be made hard to be mistaken. It is to provide a member.

  The present inventor has made various investigations on the cause of incorrectly positioning the flow path switching member after switching. As a result, it has been found that when the operator does not properly grasp the position of the flow path switching member before switching, there is a possibility that the position of the flow path switching member after switching may be mistaken. For example, in the drainage trough, the flow path switching member disposed at the first position is rotated counterclockwise by a predetermined angle (for example, 120 degrees), thereby being disposed at the second position. By rotating the flow path switching member disposed at a predetermined angle clockwise, it can be disposed at the first position. Here, when the position of the flow path switching member before switching is erroneously recognized as being located at the second position despite the first position, the flow path switching member is used to switch the flow path. May be rotated clockwise by a predetermined angle. As a result, the flow path switching member is disposed at a position where the flow inlet is closed, and the position of the flow path switching member after switching is erroneously set. From the above, the present inventor has found that it is possible for the operator to properly grasp the position of the flow path switching member before switching, thereby making it difficult to mistake the position of the flow path switching member after switching.

In the first position P1, the first opening 41 of the flow path switching member 35 overlaps the inflow port 13 of the main body 5, the second opening 42 overlaps the first outflow port 11, and the second outflow port 12 is closed by the closing member 37. Will be blocked. As a result, the inflow port 13 and the first outflow port 11 communicate with each other, and the wastewater flowing in from the inflow port 13 flows out of the first outflow port 11. The drain water flows from the inflow pipe 93 to the first outflow pipe 91 via the drain pipe 1.

  The second position P2 shown in FIG. 9 is a position where the flow path switching member 35 is rotated 120 degrees counterclockwise in FIG. As shown in FIG. 9, at the second position P2, the side wall closing portion 36C and the closing member 37 of the flow path switching member 35 face the first peripheral wall portion 15A of the main body 5 and the first peripheral wall portion 15A. It faces the formed first outlet 11 (see FIG. 2). In the second position P2, the first opening 41 of the flow path switching member 35 overlaps the second outlet 12 of the body 5, the second opening 42 overlaps the inlet 13, and the first outlet 11 is closed by the closing member 37. Will be blocked. As a result, the inflow port 13 and the second outflow port 12 communicate with each other, and the wastewater flowing in from the inflow port 13 flows out of the second outflow port 12. The drainage flows from the inflow pipe 93 to the second outflow pipe 92 via the drainage drain 1. As described above, by changing the position of the flow path switching member 35, the flow path of the drain 1 can be switched.

  Next, a procedure for switching the flow path of the drainage drain 1 will be described. Here, a procedure for changing the position of the flow path switching member 35 from the first position P1 to the second position P2 will be described.

  As described above, FIG. 3 illustrates a state where the flow path switching member 35 is disposed at the first position P1. When the flow path switching member 35 is located at the first position P1, the shaft portion 52a of the handle 50 engages with the engaging hole 30 of the second connecting portion 62 provided on the second peripheral wall portion 15B, and The portion 52b is engaged with the diameter hole 30 of the first connecting portion 61 provided at the intersection of the first peripheral wall 15A and the third peripheral wall 15C. At the first position P1, the closing member 37 is opposed to the second outlet 12 (see FIG. 2) formed in the second peripheral wall portion 15B, and closes the second outlet 12. In the present embodiment, the position where the closing member 37 is arranged so as to face the second outlet 12 at the first position P1 corresponds to the “first confirmation position” of the present invention. As described above, since the color of the upper surface 37a of the closing member 37 is yellow, the worker sees the upper surface 37a of the closing member 37 from the inspection port 19 (see FIG. 1), and the closing member 37 is in the first position. It is possible to easily confirm which of the outlet 11 and the second outlet 12 is closed.

  When switching the drain channel, first, the operator removes the lid 16 (see FIG. 1) and opens the inspection port 19 of the main body 5. Next, the arm is inserted through the inspection port 19, and the grip portion 51 of the handle 50 is grasped and pulled up. With this, the engagement state between the shaft portions 52a and 52b of the handle 50 and the engagement holes 30 of the first connection portion 61 and the second connection portion 62 is released, and the shaft portions 52a and 52b are disengaged from the engagement holes 30. Pulled out.

  When the handle 50 is pulled up, the flow path member 38 slides upward with respect to the closing member 37 until the engaging projection 47 of the closing member 37 contacts the lower end of the slide groove 39a of the rail 39 (see FIG. 7). 9). After the closing member 37 contacts the lower end of the slide groove 39a, the closing member 37 moves upward together with the flow path member 38. As described above, the side wall closing portion 36C of the flow path member 38 is inclined with respect to the vertical line (see FIG. 4). Therefore, when the flow path member 38 slides upward, the force pressing the closing member 37 against the second peripheral wall portion 15B of the main body 5 is weakened. As a result, the adhesion between the sealing member 48 of the closing member 37 and the second peripheral wall 15B of the main body 5 is weakened. According to the present embodiment, since the adhesion is weakened before the closing member 37 is pulled up, the sliding resistance between the seal member 48 and the second peripheral wall portion 15B when pulling up the flow path switching member 35 is reduced. . Therefore, the operator can pull up the flow path switching member 35 with a relatively small force.

  Next, after taking out the flow path switching member 35 from the main body 5, the operator changes the position of the flow path switching member 35 so that the closing member 37 is in a position to close the first outlet 11. I do. At this time, the worker may grasp the position of the first outlet 11 by visually checking the outflow mark 17A (see FIG. 3) attached to the inclined portion 16 of the main body 5 through the inspection port 19. After grasping the position of the first outlet 11 in this way, the operator positions the shaft portions 52b, 52a of the handle 50 directly above the engagement holes 30 of the third connection portion 63 and the fourth connection portion 64. Thus, the flow path switching member 35 is rotated 120 degrees horizontally. Then, the channel switching member 35 is inserted into the main body 5.

  When the flow path switching member 35 is inserted, the sealing member 48 of the closing member 37 comes into contact with the first peripheral wall portion 15A of the main body 5. However, since the closing member 37 is shifted downward from the side wall closing portion 36C of the flow path member 38, the sliding resistance between the sealing member 48 and the first peripheral wall portion 15A is relatively small. Therefore, the operator can insert the flow path switching member 35 into the main body 5 with a relatively small force.

  When the operator moves the handle 50 downward, first, the lower end of the closing member 37 hits the bottom wall 14 of the main body 5. When the handle 50 is moved further downward, the flow path member 38 slides downward with respect to the closing member 37. Since the side wall closing portion 36C of the flow path member 38 is inclined with respect to the vertical line, a part of the force pressing the flow path member 38 downward presses the closing member 37 against the first peripheral wall portion 15A of the main body 5. Help. Therefore, the operator can press the seal member 48 of the closing member 37 against the first peripheral wall portion 15A only by pushing the handle 50 downward, and the sealing property of the seal member 48 can be improved. This makes it possible to more reliably prevent the drainage from leaking from the first outlet 11.

  In this way, as shown in FIG. 9, when the flow path switching member 35 is disposed at the second position P2, the shaft portion 52a of the handle 50 is connected to the fourth connecting portion 64 provided on the first peripheral wall portion 15A. The shaft portion 52b is engaged with the engagement hole 30, and is engaged with the diameter matching hole 30 of the third connecting portion 63 provided at the intersection of the second peripheral wall portion 15B and the third peripheral wall portion 15C. At the second position P2, the closing member 37 is opposed to the first outlet 11 (see FIG. 2) formed in the first peripheral wall 15A. In the present embodiment, the position where the closing member 37 is arranged so as to face the first outlet 11 corresponds to the “second confirmation position” of the present invention. The operator can easily confirm that the closing member 37 has closed the first outlet 11 by visually checking the yellow upper surface 37a of the closing member 37 from the inspection port 19 at the second position P2. can do.

  As described above, according to the present embodiment, when switching the flow path of the drain mast 1, the worker checks the position of the upper surface 37 a of the closing member 37, which is an example of the checking unit, through the inspection port 19, The position of the flow path switching member 35 before switching can be confirmed. Here, when the upper surface 37a of the closing member 37 is located at a position facing the second outlet 12 (first confirmation position), the flow path switching member 35 is located at the first position P1 (see FIG. 3). You can be sure that. Therefore, the operator can grasp in advance that the position of the flow path switching member 35 will be changed from the first position P1 to the second position P2. Further, here, when the upper surface 37a of the closing member 37 is disposed at a position facing the first outlet 11 (second confirmation position), the flow path switching member 35 is moved to the second position P2 (see FIG. 9). It can be confirmed that they are arranged. Therefore, the operator can grasp in advance that the position of the flow path switching member 35 is to be changed from the second position P2 to the first position P1. As described above, by confirming the position of the flow path switching member 35 before the switching, it is possible to make it difficult to mistake the switching destination of the flow path.

  In this embodiment, as shown in FIG. 3, at least the upper surface 37a of the closing member 37 is colored differently from the periphery of the upper surface 37a, so that the position of the closing member 37 can be easily visually recognized. Therefore, it is easy to confirm the position of the flow path switching member 35 before switching the flow path.

  In the present embodiment, the flow path switching member 35 is disposed with respect to the main body 5 so that the side wall closing portion 36C of the side wall portion 36 of the flow path switching member 35 faces the second outlet 12, so that the flow path switching is performed. The member 35 can be appropriately arranged at the first position P1. Further, by disposing the flow path switching member 35 with respect to the main body 5 so that the side wall closing portion 36C of the flow path switching member 35 faces the first outlet 11, the flow path switching member 35 is moved to the second position P2. Can be properly arranged.

  In the present embodiment, as shown in FIG. 9, when the flow path switching member 35 is disposed at the second position P2 on the first peripheral wall portion 15A of the peripheral wall portion 15 of the main body 5, the shaft portion of the handle 50 is provided. There is provided a fourth connecting portion 64 in which the engaging hole 30 that engages with the protruding portion 52c of the 52a is formed. Therefore, by engaging the projecting portion 52c of the shaft portion 52a with the engaging hole 30 provided in the first peripheral wall portion 15A, the flow path switching member 35 can be appropriately arranged at the second position P2. .

  As shown in FIG. 3, an engagement hole 30 is formed in the second peripheral wall 15 </ b> B to engage with the protrusion 52 c of the shaft 52 a when the flow path switching member 35 is disposed at the first position P <b> 1. A second connecting portion 62 is provided. Therefore, by engaging the projecting portion 52c of the shaft portion 52a with the engaging hole 30 provided in the second peripheral wall portion 15B, the flow path switching member 35 can be appropriately arranged at the first position P1. .

  The third peripheral wall portion 15C of the peripheral wall portion 15 is not provided with a portion that engages with the projecting portion 52c of the shaft portion 52a. As a result, the flow path switching member 35 cannot be disposed at a position where the inflow port 11 is closed. Therefore, it is possible to prevent the flow path switching member 35 from being erroneously arranged at a position where the inflow port 11 is closed.

  In the present embodiment, outflow marks 17A and 17B indicating that drainage flows out of the main body 5 are attached to the first inclined portion 16A and the second inclined portion 16B of the inclined portion 16. The third inclined portion 16C is provided with an inflow mark 17C indicating that drainage flows into the main body 5 more. Thus, the positions of the first outlet 11 and the second outlet 12 can be confirmed by visually checking the outflow marks 17A and 17B, and the position of the inlet 13 can be confirmed by visually checking the inflow mark 17C. You can check. As described above, since the positions of the inflow port 13, the first outflow port 11, and the second outflow port 12 can be confirmed, the operator arranges the flow path switching member 35 at a position that closes the inflow port 13. Can not be.

  The drainage masque 1 according to one embodiment has been described above. In the above-described embodiment, the confirmation unit according to the present invention is configured by the upper surface 37a of the closing member 37. However, the confirmation unit may be configured by the curved portion 57a (see FIG. 3) of the invert 57 formed on the bottom wall 49 of the flow path switching member 35. The curved portion 57a is a portion having a shape that is recessed toward the closing member 37 in a plan view. Therefore, as shown in FIG. 3, when the flow path switching member 35 is located at the first position P <b> 1, the curved portion 57 a is recessed toward the second outlet 12 closed by the closing member 37. Further, as shown in FIG. 9, when the flow path switching member 35 is disposed at the second position P2, the curved portion 57a is recessed toward the first outlet 11 closed by the closing member 37. Therefore, by checking the direction in which the curved portion 57a of the invert 57 is depressed, it is possible to check the position of the flow path switching member 35 before switching the flow path.

  In addition, the confirmation unit may be configured by a protruding portion 52c of the shaft portion 52a of the handle 50 that protrudes outward from the side wall closing portion 36C to the outside of the flow path switching member 35. The projection 52c of the shaft 52a projects toward the closing member 37 in plan view. Therefore, as shown in FIG. 3, when the flow path switching member 35 is disposed at the first position P <b> 1, the protrusion 52 c is located above the second outlet 12 (see FIG. 2) closed by the closing member 37. Be placed. When the flow path switching member 35 is located at the second position P2, the protrusion 52c is located above the first outlet 11 (see FIG. 2) closed by the closing member 37. Therefore, by confirming the position of the protruding portion 52c, the position of the passage switching member 35 before switching the passage can be confirmed.

<Other embodiments>
In the above-described embodiment, the protrusion of the present invention is configured by a part of the handle 50 (here, the protrusion 52c of the shaft 52a), but may be configured by a part different from the handle 50. For example, as shown in FIG. 10, a plate-like flange protruding outward from the side wall closing member 36C from the side wall closing portion 36C to the side wall closing portion 36C of the side wall portion 36 of the flow path switching member 35 in plan view. 80 may be formed. In this case, the confirmation section according to the present invention is constituted by the flange 80. The flange 80 projects from the side wall closing portion 36C toward the closing member 37 in a plan view. Therefore, when the flow path switching member 35 is disposed at the first position P1, the flange 80 is disposed above the second outlet 12 closed by the closing member 37. Although not shown in detail, when the flow path switching member 35 is disposed at the second position P2, the flange 80 is disposed above the first outlet 11 closed by the closing member 37. Therefore, by confirming the position of the flange 80, the position of the passage switching member 35 before switching the passage can be confirmed.

  As shown in FIG. 10, a mark 81 may be provided on the upper surface of the flange 80. Here, “×” is marked on the upper surface of the flange 80 as the mark 81, but the type of the mark 81 is not particularly limited. Since the mark 81 is provided on the flange 80 in this manner, the operator can easily confirm the position of the flange 80 through the inspection port 19.

  Further, the confirmation unit may be constituted by a handle 150 as shown in FIG. The handle 150 shown in FIG. 11 includes a gripper 151 and shaft portions 152a and 152b extending from both ends of the gripper 151. The shape of the gripper 151 is, for example, a bent plate shape. The handle 150 is bridged over the side wall 36 of the flow path switching member 35. Specifically, the shaft 152a of the handle 150 is provided at the side wall closing portion 36C of the side wall 36, and the shaft 152b of the handle 150 is provided at the intersection of the first side wall 36A and the second side wall 36B. I have. In the present embodiment, a mark 155 is provided on the gripper 151. The mark 155 is a mark indicating the position of the side wall closing portion 36C of the side wall portion 36 of the flow path switching member 35, in other words, the position of the closing member 37. The type of the mark 155 is not particularly limited. For example, a character “closed side →” is attached to the gripper 151 as a mark 155. This “→” is an arrow pointing to the side wall closing portion 36C. Thus, the operator can confirm the position of the side wall closing portion 36C by visually recognizing the mark 155 attached to the grip portion 151 of the handle 150. Therefore, by visually recognizing the mark 155 through the inspection port 19, the position of the flow path switching member 35 before switching the flow path can be confirmed in advance. The position of the gripper 151 to which the mark 155 is attached is not particularly limited, and may be, for example, on the side surface and the upper surface of the gripper 151.

  Further, the confirmation unit may be constituted by a handle 250 as shown in FIG. The handle 250 shown in FIG. 12 is bridged over the side wall 36 of the flow path switching member 35. One end of the handle 250 is provided at a side wall closing portion 36C of the side wall portion 36, and the other end of the handle 250 is provided at an intersection between the first side wall portion 36A and the second side wall portion 36B. Here, the handle 250 has a first handle portion 251 disposed on one end when the handle 250 is divided into two in the axial direction A1 of the handle 250, and a second handle disposed on the other end opposite to the one end. A handle portion 252. Here, the division into two is a division line that passes through the center of the handle 250 and is divided at a division line that is orthogonal to the axial direction A1. The first handle 251 and the second handle 252 have asymmetric shapes. Here, the asymmetrical shape refers to an asymmetrical shape in line symmetry with the dividing line as an axis. However, the asymmetric shape refers to an asymmetric shape with respect to a point symmetric about the center of the handle 250 and the symmetric point. For example, the shape of the first handle portion 251 is a rectangular shape whose width (here, the length in the direction orthogonal to the axial direction A1) is the first width W1, and the shape of the second handle portion 252 has a width of It has a rectangular shape having a second width W2 shorter than the first width W1.

  Thus, the operator can easily grasp the position of the first handle portion 251 from the shape of the handle 250. Here, the first handle portion 251 is disposed closer to the side wall closing portion 36C than the second handle portion 252. Therefore, when the flow path switching member 35 is disposed at the first position P1, the second outlet 12 closed by the closing member 37 is disposed on the first handle 251 side. Although not shown in detail, when the flow path switching member 35 is disposed at the second position P2, the first outlet 11 closed by the closing member 37 is disposed on the first handle part 251 side. I have. Therefore, by visually recognizing the handle 250 through the inspection port 19, the operator can confirm the position where the side wall closing portion 36C is arranged from the position of the first handle portion 251. Therefore, by visually recognizing the handle 250, the operator can confirm the position of the flow path switching member 35 before switching the flow path.

  In the above embodiments, the handles 50, 150, and 250 are provided rotatably with respect to the flow path member 38, but may be fixed so as not to rotate with respect to the flow path member 38.

  In each of the above embodiments, the peripheral wall portion 15 of the main body 5 is formed in a substantially triangular shape in plan view by the first peripheral wall portion 15A, the second peripheral wall portion 15B, and the third peripheral wall portion 15C. The portion 36 was formed in a substantially triangular shape in plan view by the first side wall portion 36A, the second side wall portion 36B, and the side wall closing portion 36C. However, the peripheral wall portion 15 may be formed in a circular shape in a plan view by the first peripheral wall portion 15A, the second peripheral wall portion 15B, and the third peripheral wall portion 15C, and the side wall portion 36 may include the first side wall portion 36A, The second side wall portion 36B and the side wall closing portion 36C formed a circular shape in plan view.
