A valve chamber 5 communicating with the valve chamber 7 is formed, and an operating shaft 8 that moves forward and backward by screwing is inserted from the outside of the valve housing 1 so as to be coaxial with the center axis of the valve seat holes 3 and 4.
Two valve bodies 11 and 12 are slidably mounted with a distance maintained between them, and correspond to the valve seat holes 3 and 4, respectively, and a spring 13 is interposed between the two valve bodies 11 and 12. The valve bodies 11 and 12 are biased toward the valve seat holes 3 and 4, respectively, and the valve seat holes 3 and 4 are moved forward and backward by the operation shaft 8.
4 is characterized in that slip rings 17 and 18 made of a low-friction material are interposed between the spring 13 and at least one of the valve bodies 11 and 12. Self-closing prevention mechanism for switching valves.
