閉弁。[Claims for Utility Model Registration] (1) Primary fluid pressure and secondary fluid pressure are applied to both sides of the piston, and the main valve body is linked to the movement of the piston due to the differential pressure to open and close the flow path. In the automatic opening/closing valve, an auxiliary piston rod 22 moves the piston 16 in the opposite direction of the piston rod 21 that transmits the movement of the piston 16 to the main valve body 9.
An automatic opening/closing valve that protrudes from the piston rod and has the piston rod 21 and the auxiliary piston rod 22 slidably fitted into guide holes 24 and 26, respectively. (2) In addition to the configuration described in claim (1), the piston 1
Reference numeral 6 denotes an automatic opening/closing valve in which a piston ring 20 is attached to the outer circumferential surface of the piston 16 in a sliding manner with respect to the cylinder 11, and the piston ring 20 always has a gap with the cylinder 11.
