Referring to the operation of the present invention made of such a configuration as follows. As shown in FIG. 5A, the plunger 20 of the valve body 10 is connected to the first port connection position, that is, the main valve in a state in which the connection socket 30 is not mounted on the coupling portion 14 of the valve body 10. The sieve 21 moves to the position where the second branch port 13 is closed by the elastic restoring force of the spring 22, and the auxiliary valve body 61 of the auxiliary plunger 60 is the elastic restoring force of the spring 63. The main port 11 is connected to the first branch port 12 because it is in the inlet closing position for closing the flow path inlet 13a of the second branch port 13 by. Therefore, the fluid flows from the main pipe 15 connected to the main port 11 to the first branch pipe 16 connected to the first branch port 12 or from the first branch pipe 16 to the main pipe 15. Will flow.

In this state, when the flow of the fluid is to be switched to the second branch port 13, the coupling of the connection socket 30 to the coupling portion 14 of the valve body 10 as shown in Figs. 5b and 5c. By combining the unit 31, the main port 11 can be connected to the second branch port 13 easily and quickly.

That is, as shown in FIG. 5B, after the coupling portion 14 of the valve body 10 is inserted into the coupling portion 31 of the connection socket 30 and coincided with the coupling portion 30, the handle 84 is pulled and pushed in, FIG. As shown in 5c, the auxiliary plunger 60 of the valve body 10 is pushed by the pusher 40 of the connecting socket 30 and the spring 63 is compressed, so that the flow path inlet of the second branch port 13 ( 13a) is moved from the inlet closing position to close the inlet opening position to open the flow path inlet 13a, and at the same time the shaft 23 of the plunger 20 is pushed by the auxiliary plunger 60, the spring 22 ) Is compressed and the plunger 20 closes the first branch port 12 at the first port connection position (see FIG. 5A) that opens the first branch port 12 and closes the second branch port 13. The second branch port 13 is moved to the second port connection position that opens.

Therefore, the flow path inlet 13a of the second branch port 13, which is closed by the auxiliary valve body 61 of the auxiliary plunger 60, is opened, and the second branch port 13 communicates through the distribution hole 62. At the same time, since the main valve body 21 of the plunger 20 opens the second branch port 13 and closes the first branch port 12, the main port 11 is the second branch port 13. ).

On the other hand, the socket valve body 50 of the connecting socket 30 is pushed by the coupling portion 14 of the valve body 10 to move from the socket closed position (see Fig. 5a) to the socket opening position as the spring 51 is compressed. As a result, the socket valve body 50 closing the flow hole 41a of the pusher 40 opens the flow hole 41a, so that the flow passage 40a-pusher 40 of the connection socket 30 is closed. A connecting socket (11) is connected to the main pipe (15) connected to the main port (11) by communicating with the distribution hole (62a) of the auxiliary plunger (60) and the second branch port (13) of the valve body (10). Fluid flows to the second branch pipe 17 connected to 30, or fluid flows from the second branch pipe 17 to the main pipe 15.

In this state, when the flow of the fluid is to be switched back to the main port 11 and the first branch port 12, it is simply performed by separating the connecting socket 30 from the valve body 10. That is, when the coupling portion 14 of the valve body 10 and the coupling portion 31 of the connecting socket 30 are separated, the plunger 20 of the valve body 10 is spring 22 as shown in FIG. 5A. The first branch port 12 is opened and the second branch port 13 is closed by the elastic restoring force of the spring, and the auxiliary plunger 60 is also applied to the elastic restoring force of the spring 63. Since the auxiliary valve body 61 is moved to the inlet closing position for closing the flow path inlet 13a of the second branch port 13, the main port 11 and the first branch port 12 are connected, thereby Fluid flows between the main pipe 15 connected to the main port 11 and the first branch pipe 16 connected to the first branch port 12.

As described above, the present invention is a simple and quick operation by the one-touch method of attaching and detaching the connecting socket 30 to the valve body 10 from the main port 11 to the first branch port 12 or the second branch port 13. The flow of fluid can be selectively switched, and the connecting socket 30 separated from the valve body 10 moves the socket valve body 50 from the socket opening position to the socket closing position by the elastic restoring force of the spring 51. Therefore, since the flow hole 41a of the pusher 40 is closed, the fluid remaining in the flow path 40a of the connecting socket 30 does not leak to the outside.

And, by the coupling means for detachably attaching the valve body 10 and the connecting socket 30, as shown in Figure 5b, by pulling the coupling holder 73 is moved to the ball press release position, spring As the 74 is compressed, the engaging release groove 73b of the engaging holder 73 is positioned in the engaging ball 72 so that the engaging ball 72 can be inserted into the pressing release groove 73b, thereby engaging the engaging ball ( 72 allows sliding of the engaging portion 14 of the valve body 10 and the engaging portion 31 of the connecting socket 30 while slidingly contacting the outer surface of the engaging portion 14 of the valve body 10.

When the coupling portion 14 of the valve body 10 is completely inserted into the coupling portion 31 of the connection socket 30, the coupling ball 72 is engaged with the coupling portion 14 of the valve body 10. When the coupling holder 73 is positioned at 71 and then the coupling holder 73 is released, the coupling holder 73 is moved to the ball pressing position by the elastic restoring force of the compressed spring 74 as shown in FIG. Since the pressure protrusion surface 73a of the 73 presses the coupling ball 72, the coupling ball 72 is prevented from being separated from the insertion ball 72 while being inserted from the coupling groove 71.

When the connection socket 30 is to be separated from the valve body 10, as in the case of engagement, when the coupling holder 73 is pulled out and moved to the ball press release position, the spring 74 is compressed to engage the coupling holder. The pressure releasing groove 73b of the 73 is positioned in the coupling ball 72 so that the coupling ball 72 can be inserted into the pressure releasing groove 73b, so that the coupling ball 72 is separated from the coupling groove 71. It is possible to separate the engaging portion 14 of the valve body 10 and the coupling portion 31 of the connecting socket 30 while sliding contact with the outer surface of the coupling portion 14 of the valve body 10.

In this coupling means, the valve body 10 and the connection socket 30 are coupled to each other by the elastic restoring force of the compressed springs 22 and 63 and the pressure of the fluid flowing in the flow path in coupling the valve body 10 and the connection socket 30. It is possible to reliably prevent the 30 from being separated.

In addition, by the link mechanism 80 of the present invention, the coupling plate 83a can be held by the connection bracket 42 of the connection socket 30 as shown in FIG. 5B, and then the handle 84 is engaged in the engagement direction. When pulled out, since the linear movement bar 82 is pulled by the first and second link bars 85 and 86 as illustrated in FIG. 5C, the coupling plate 83a moves the connection socket 30 to the valve body. Pulling it to the (10) side, it becomes possible to forcibly couple the valve body 10 and the connecting socket 30.

Therefore, the elastic body of the spring (22,63) acting when the valve body 10 and the connecting socket 30 is coupled and the force greater than the pressure of the fluid can be easily combined with less force than when the operator directly coupled. When the valve body 10 and the connecting socket 30 are separated from each other, the release plate 83b may contact the coupling holder 73 as shown in FIG. 5C, and in this state, the handle 84 is separated. 5B, since the linear movement bar 82 is moved in the separation direction by the first and second link bars 85 and 86, the connecting socket 30 is separated from the valve body 10. You can do it.

The present invention is not limited to the embodiments described so far, and various changes, modifications, or substitutions may be made by those skilled in the art within the technical spirit and claims of the present invention, and such embodiments are the present invention. It should be understood to fall within the scope of.

As described above, according to the three-way valve having a detachable variable function according to the present invention, when the main port is connected to the first branch port, the connection socket coupled to the second branch port is removed to remove the second branch pipe. By using in the state, it is possible to prevent the second branch pipe from occupying the space unnecessarily or to complicate the surroundings. When connecting the main port to the second port, the connecting socket is connected to the second branch port. The simple flow of one-touch method allows the flow of fluid to be switched from the first branch port to the second branch port, as well as the operation of attaching and detaching the connecting socket to the second branch port of the valve body and simultaneously switching the flow of fluid. Since the operation is made is an industrially useful invention that is more convenient to use.
