[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a solenoid valve, and particularly to a solenoid valve that can change the direction of one of a plurality of flow channels.

[Prior art and problems to be solved]

Generally, in the case of a solenoid valve that has a plurality of flow paths and is capable of switching between these flow paths, the fifth
It is constructed as shown in FIG. 6 and FIG.

That is, the body 34 has a flow path 31, and a flow path 2 that is perpendicular to the flow path and located slightly above the flow path.
Solenoid valves 35 and 36 are provided at the intersections of the flow paths 31 and 32 and at the intersections of the flow paths 31 and 33, respectively. Valve 35, 36
Each of the intersections is opened and closed during operation.

However, in the conventional solenoid valve as described above, each flow path 31, 32, 33 is formed integrally with the body 34, so each flow path 31, 32, 33 is formed integrally with the body 34.
The orientation of the tube 33 is determined at the time of manufacture, and therefore, there have been cases where the tube cannot be used as is due to the piping.

In order to achieve the above object, this device has a flow path on the bottom surface of the housing and a communication path on the side surface, and the flow path and the communication path are connected according to the operation of a valve provided inside when electricity is applied. Using two solenoid valves that can communicate with each other, a rotating member is positioned between the communication passages provided on the sides of both solenoid valves, and both solenoid valves and the rotating member are integrated via a connecting member. The rotating member is configured to be rotatable in a direction perpendicular to the axis of the communication passage, and to connect a passage communicating between the communication passages of both the solenoid valves and a flow passage communicating with this passage. This constitutes a solenoid valve characterized by:

[Effect]

By adopting the above-mentioned means, this idea
Since the flow path of the rotating member can be changed with respect to the flow path of the solenoid valve, piping to the flow path is easy and a space in the vicinity can be secured.

〔Example〕

Embodiments of this invention shown in the drawings will be described below.

Figures 1 to 4 show a solenoid valve according to this invention, and this solenoid valve has two channels 2 and 3 that open on the bottom surface, and a flow path from the bottom surface to the side surface. The flow path 1 is provided with a flow path 1 whose opening direction can be arbitrarily changed between the two.

That is, the solenoid valve according to this invention has two solenoid valves 1 that can open and close the flow between a flow path opening at the bottom and a flow path opening at the side.
2 and 13 communicate with communication passages opened on the sides of both solenoid valves 12 and 13, and have a flow passage opening on the lower face, and the direction of the flow passage opening on the lower face can be changed. It is composed of a rotating member 27.

The two solenoid valves 12 and 13 have cylindrical housings 16 and 17 with flow passages 2 and 3 opening on the lower surface and communication passages 4 and 5 opening on the lower side surfaces, respectively. 16,
Inside 17, movable valves 6, 7 are provided.

The valve bodies 10, 11 of the valves 6, 7 are connected to valve seats 8, 9 formed on the bottom surfaces of the housings 16, 17.
It is possible to sit on each of them.

Furthermore, inside the cylindrical housings 16 and 17, a movable iron core 1 is provided above the valves 6 and 7.
4, 15, fixed cores 18, 19, and the movable cores 14, 15 are provided between the movable cores 14, 15 and the fixed cores 18, 19 to press the movable cores 14, 15 downward to open the valve bodies 10, 11. Spring 2 pressing against seats 8 and 9
0, 21, and coils 22, 23 are wound around the outer periphery of the cylindrical housings 16, 17.

Two solenoid valves 12, 13 as above
is formed.

On the other hand, the rotary member 27 provided between the two solenoid valves 12 and 13 has a passage 28 opening on both sides, and a flow passage 1 opening downward communicating with the center of the passage 28. There is.

A rotating member 27 is connected between the two solenoid valves 12 and 13 configured as described above to form an integral structure.

That is, to explain the connection between the solenoid valves 12, 13 and the rotating member 27, first, the communication passages, 5, on the sides of both the solenoid valves 12, 13,
The two communication passages 4 and 5 face each other, and passages 28 opened on both sides of the rotating member 27 are aligned between the two communication passages 4 and 5.

In this case, both the solenoid valves 12, 13
The periphery of the communicating passages 4 and 5 protrudes in an annular shape, and the ends of the passage 28 on both sides of the rotating member 27 are
Since it is recessed so as to receive the annularly protruding portions of the communication passages 4 and 5, the O-rings can be positioned outside the annular protrusions for assembly.

After that, using the connecting member 24, which is a U-shaped yoke consisting of two horizontal parts and a vertical part connecting both horizontal parts, a solenoid valve is inserted into two notches 24a formed in one horizontal part. The upper parts of the solenoid valves 12 and 13 are respectively positioned, and the central parts of the solenoid valves 12 and 13 are respectively positioned within the two notches 24b provided in the other horizontal part, and the mounting plate 25 is placed between the two notches 24b. By positioning and fixing with screws 26, the entrance portions of both notches 24b formed on the other horizontal portion are connected to the mounting plate 25.
It's starting to get blocked.

In addition, as mentioned above, two solenoid valves 1
The connecting member 24 that fixes the rotary member 27 between the two solenoid valves 1 and 13 is connected to the
The upper and lower portions of the coils 22 and 23 are sandwiched between the horizontal portions and fixed.

Next, the operation of the above will be explained.

In the structure as described above, the three channels 1, 2, and 3 can be freely used for input and output. For example, the channel 1 provided in the rotating member 27 A case will be described in which the flow paths 2 and 3 of the solenoid valves 12 and 13 are piped for fluid input and fluid output.

When fluid such as pressurized air or hot water is supplied to the flow path 1, the supplied fluid flows through the passage 28 of the rotating member 27.
The communication passages 4 and 5 of the solenoid valves 12 and 13 are reached through the solenoid valves 12 and 13.

Therefore, the coil 2 of the solenoid valve 12
When the valve 6 is opened by applying electricity to the solenoid valve 1, the supplied fluid flows out from the flow path 2, and the solenoid valve 1
When the coil 23 of No. 3 is energized, it flows out from the flow path 3.

Therefore, by switching the energization to the coils 22 and 23, the fluid supplied to the flow path 1 can be caused to flow out from the flow path 2 or the flow path 3.

Note that if the flow path 2 is used for inputting fluid, it can flow out from the flow path 1 when the coil 22 is energized, and at this time, by energizing the coil 23, the fluid can flow out from the flow path 1.
And it can be made to flow out from the flow path 3, and the flow paths 1 and 3 can be used for output.

In addition, if the flow path 3 is used for inputting fluid, it can flow out from the flow path 1 when the coil 23 is energized, and at this time, by energizing the coil 22, the fluid can flow out from the flow path 1.
And it can be made to flow out from the flow path 2, and the flow paths 1 and 2 can be used for output.

If the direction of the piping to the flow path 1 is perpendicular to the piping of the flow paths 2 and 3 due to the circumstances of the piping to each flow path 1, 2, and 3, the rotating member 27 is rotated. This allows for easy piping.

That is, since the rotating member 27 is rotatable about the axes of the communicating passages 4 and 5 of both the solenoid valves 12 and 13, the direction of the flow passage 1 is toward the front and back in FIG. It can be changed in the left-right direction in FIG.

Therefore, the direction of flow path 1 can be changed with respect to flow paths 2 and 3 within a rotatable range, thereby securing space for piping and improving workability. It is something that can be achieved.

That is, when supplying fluid to devices installed in the device, the solenoid valve of this invention is built into the device, and piping is provided between the flow paths 2 and 3 and the device to which the fluid is supplied. Since the direction of the flow path 1 can be changed, connection to the outside is easy, and space can be secured and workability can be improved.

[Effect of idea]

By configuring this idea as described above,
Since the direction of the flow path of the rotating member can be changed, for example, when assembling it into a device to supply fluid to the device, connect the flow paths of the solenoid valves to each device, and Piping is easy if the flow path is connected to the supply side, and since the direction of the flow path of the rotating member can be changed, the space inside the device can be used effectively, making piping easy and easy to connect. This has the effect of making it possible to make efficient use of space.
