A valve push-up body is provided in the bottomed cylinder so that it opens when the liquid pressure on the side is low and allows the liquid inlet hole and the liquid outlet hole to communicate with each other, and closes when the liquid pressure on the side side is high. and an elastic member provided in a bottomed cylinder so as to be able to always bias this valve pusher. (2) A utility model registration request characterized in that the bottom of the bottomed cylindrical body is fitted with an adjustment screw assembly that can adjust the elastic force of the elastic member or the vertical position of the valve pusher. A flow path opening/closing valve according to scope 1. (3) The valve push-up body includes an elastic member receiving part that receives the upper end of the elastic member, a lower end fixedly attached to the elastic member receiving part, and an upper end that can come into contact with the on-off valve. The flow path opening/closing valve according to claim 1, which is characterized by comprising a push rod protruding so as to be able to move.
