止保持装置。A main valve for opening and closing the valve port is connected to the main valve via a substantially cylindrical piston shaft to the secondary chamber of the valve body, which is divided into a primary chamber and a secondary chamber by a partition wall having a valve port. A cylinder chamber is provided with a piston having a larger pressure-receiving area than the main valve, and is supported by the upper cover of the valve body. The main valve has a water passage hole that introduces pressurized water from the primary side chamber of the main body, and a pressurized water discharge hole that is provided in the cylinder chamber and can be opened and closed by a pilot valve installed outside the cylinder chamber, facing the valve body. The water supply valve, in which the main valve can be driven via a piston by the difference between the pressure in the primary side chamber and the pressure in the pressurized chamber, is exposed to the valve body, the valve port, and the main valve from the outside of the primary side of the valve body. An auxiliary valve is provided at the tip of the main valve, and a support shaft positioned within the piston shaft is attached so as to be movable forward and backward, and the water passage hole of the main valve is freely opened and closed within the piston shaft, and when the water passage hole is closed. A valve closing/holding device for a water supply valve comprising the main valve pressed against a valve port.
