弁。An inlet and an outlet are provided on the sides, a drain is provided at the lower end, and a drain is provided between the outlet and the drain. There is a ring-shaped packing that communicates and blocks the passage between the inlet and the outlet, and a ring-shaped packing or diaphragm that divides the upper chamber of the cylinder into an upper spring chamber and a lower pressure receiving chamber. It basically consists of a piston that receives a downward force from an adjustable spring, and an operating rod that connects the piston so that it can move up and down, and is normally attached to the lower end of the piston. The drain port is closed with a ring-shaped gasket or a drain valve connected to the bottom end, and when draining water, the above operating rod is raised, and after the piston closes the inlet port, the drain port is opened and the water is discharged from the secondary side. A pressure reducing valve for use in cold regions, characterized in that the pressure is discharged.
