Definitions

  • connection fitting for a fluid-carrying arrangement in particular a radiator assembly, comprising a housing and a threaded member having a passageway and which is rotatably mounted in a passage opening in the housing about an axis.
  • connection fitting is made, for example DE 295 02 670 U1 known.
  • the threaded element is rotatably mounted in the housing, but secured by a mounting ring in the axial direction. Now you can turn the threaded element and screw its thread into another thread. In this case, the orientation of the housing in the room can be changed as long as the threaded element has not been sufficiently tightened.
  • the invention will be described below with reference to a radiator valve. But it is also applicable to other problems in which a housing with another part of an arrangement, such as a pipe or the like, must be connected.
  • Radiators are often regarded as furnishings whose design demands are stringent. A successful design should not be disturbed by a connection with a radiator valve. Although the valve can also be designed visually appealing. The mechanical connection However, between the radiator and the valve in many cases disturbs the appearance.
  • the invention has for its object to facilitate the installation of the connection fitting.
  • connection fitting of the type mentioned above in that an actuating element rotatably and axially slidably connected to the threaded member and the threaded member between a retracted end position and an extended end position and in the housing is parallel to the axis displaceable.
  • the threaded element is in the extended end position against a stop in the housing.
  • This is a relatively simple measure to be able to exert the corresponding forces on the housing by the threaded element.
  • the stop is formed by a closing ring, which is arranged in a groove in a channel wall surrounding the channel opening.
  • the locking ring which may be formed for example as a spring ring, makes it possible to insert the threaded element in the housing.
  • the locking ring is slightly compressed so that it fits into the channel opening. It is expediently located in a groove which is formed on the circumference of the threaded element. Once the locking ring then reaches the groove in the channel wall, it can expand and then partially covers the cross section of the threaded element and partially covers the cross section of the housing.
  • the threaded element has an external thread which protrudes in the retracted end position with n threads out of the actuating element, wherein n is in the range of 1 to 5, in particular in the range of 1 to 3.
  • the external thread basically only needs to protrude from the actuator with a length sufficient to engage the external thread with a corresponding internal thread of the counterpart. Once this engagement is made, the threaded element is retracted by turning further into the counterpart, without the housing would have to be located further away from the counterpart.
  • a sealing ring is arranged on the housing-side end of the thread. This sealing ring then ensures the tightness between the threaded element and the counterpart.
  • the sealing ring is arranged on a cone-like surface.
  • This conical surface has its smallest diameter in the area of the external thread. This sealing ring will always slide as close as possible to the external thread under its residual stress and thus seal a connection between the threaded element and the counterpart in the area of the thread pairing.
  • the actuating element with the threaded element in the extended end position forms a receiving groove into which the sealing ring can be pressed. This ensures at the same time that also the actuating element can be acted upon by the sealing ring. Thus, the friction between the actuating element and the counterpart is increased, so that an accidental release of the connection fitting is difficult.
  • the threaded element In the region of its end arranged in the housing, the threaded element preferably has an annular seal which, when moved from the retracted end position to the extended end position, slides along a sealing surface in the housing. This ring seal ensures the tightness between the housing and the threaded element.
  • the actuating element preferably has a cutting edge on its front side facing away from the housing. This cutting edge then penetrates into the paint or ink layer of the counter element. This also contributes an increased friction between the actuator and the counterpart at. In addition, one can derive in this way an electrically conductive connection between the actuator and the counterpart, if desired.
  • the actuating element has a friction edge on its end facing the housing. This friction edge cooperates with the housing and increases the friction between the actuator and the housing. This also helps prevent inadvertent release of the connection fitting, because the actuating element, once it has tightened the connection fitting once against the counter element, can only be turned back with larger external forces.
  • the friction edge cooperates with an inclined surface in the housing. This can produce relatively high surface pressures. The friction edge can be pressed into the inclined surface, so to speak.
  • the actuating element has the same outer surface as the housing. In this case, you can hide the connection between the connection fitting and the counter element so to speak, ie there will be no visible elements whose outer design differs from the design of the housing, as would be the case for example with a threaded element made of brass, if it is visible would. This improves the design possibilities with regard to the external appearance.
  • FIG. 1 shows a connection fitting 1 in the form of a radiator valve with a housing 2 and a threaded element 3.
  • the connection fitting 1 should be connected to a counter element 4, which is formed in the present embodiment by a radiator.
  • the counter element 4 has for this purpose an internal thread 5.
  • the threaded element 3 has an external thread 6, which fits to the internal thread 5.
  • the threaded element 3 has a through-channel 7.
  • the threaded element 3 is inserted into a channel opening 8 in the housing.
  • the channel opening 8 is surrounded by a channel wall 9, in which a groove 10 is arranged.
  • a locking ring 11 which is formed as a spring ring and is biased radially outwards.
  • the threaded element 3 has a circumferential groove 12 into which the locking ring 11 can be pressed when the threaded element 3 is inserted into the housing 2. Once the locking ring 11 reaches the groove 10 in the channel wall 9, it can expand. He then projects with a part of its cross section in the groove 10 and with a part of its cross section in the circumferential groove 12, so that the threaded element 3 can not be pulled out of the housing 2, as in FIG. 2 can be seen.
  • the threaded element 3 is accordingly axially displaceable and rotatably mounted in the housing 2.
  • the housing 2 defined by an end wall 13 of the channel opening 8, which may also be referred to as a channel bore, a retracted end position for the threaded element 3.
  • the threaded member 3 can be inserted as far into the housing 2, until it on the end wall 13 to the plant comes.
  • the locking ring 11 forms, as is made FIG. 2 it can be seen, a stop which defines an extended end position of the threaded element 3 in the housing 2.
  • the threaded element 3 can be moved so far out of the housing 2 until a boundary 14 of the circumferential groove 12 comes to bear against the locking ring 11, wherein the locking ring 11 rests against the axially outer boundary of the groove 10.
  • An actuating element 15 is rotatably connected to the threaded element 3.
  • the threaded element 3 in the actuating element 15 is axially displaceable.
  • the term "axial" refers to an axis 16 of the passage channel 7.
  • the connection between the actuating element 13 and the threaded element 3 can be carried out in different ways, for example via a toothing, a splined arrangement, a tongue and groove connection or the like.
  • the external thread 6 protrudes with two to three threads out of the actuator 15 when the threaded member 3 is in the retracted end position, the in FIG. 1 is shown. In this final position, the External thread 6 are brought into engagement with the internal thread 5 on the counter element 4. Accordingly, one needs only as much additional space for mounting the connection fitting 1 on the counter element 4, as the protruding from the actuator 15 threads of the threaded element 3 need.
  • the actuator 15 may be provided with a torque-engaging surface 17, such as a hexagon, to which a hex key can engage.
  • An annular seal 18 is disposed at the end of the threaded member 3 which is inserted in the housing 2. This ring seal slides along a sealing surface 19, when the threaded member 3 from the in FIG. 1 shown retracted end position in the in FIG. 2 shown extended end position is moved.
  • a sealing ring 20 is arranged, which is arranged on a conical surface 21.
  • the sealing ring 20 is then, when the threaded member 3 is screwed into the counter element 4, expanded and pressed into a groove 22 which is formed by the actuating element 15 and the threaded member 3 together.
  • the sealing ring 20 seals the threaded element 3 against the counter element 4 on the one hand.
  • the friction is increased, which must be overcome in order to further rotate the actuator 15.
  • the actuating element 15 has a cutting edge 25 which digs into the counter element 4 when the connection fitting 1 is clamped firmly on the counter element 4.
  • the cutting edge 22 may be a paint or other surface coating cut through the counter element 4. This is also a measure to increase the torque that is necessary for releasing the connection fitting 8 from the housing 4.
  • the actuating element 3 has a friction edge 23, which comes to rest on an inclined surface 24 in the housing 2.
  • This friction edge 23 can also dig in here in order to increase the frictional engagement between the actuating element 15 and the housing 2.
  • connection fitting 1 usually you will mount the connection fitting 1 by attacking with a tool on the actuator 15. By turning the actuating element 15, the external thread 6 is screwed further into the internal thread 5. As a result, the threaded element 3 is pulled into the counter element 4. After a certain time, when the threaded member 3 rests against the housing 2 via the locking ring 11, the housing is also pulled in the direction of the counter-element 4, thereby clamping the actuating element 15 between itself and the counter-element 4.
  • the embodiment shows an angle valve.
  • the present invention is also applicable to through valves, connecting flanges or the like.
