Claims

[Scope of utility model registration request]

The valve body has an inlet at the top of the side wall, an outlet at the bottom, a drain at the bottom end, and basically three cylinders inside, above and below the inlet and below the outlet. A piston that moves up and down inside the main body to select the water flow/drainage state, and a ring-shaped gasket that comes into close contact with and detaches from the cylinder above the inlet are installed, and the piston is movably connected to the lower end, and the handle The piston is equipped with basically four ring-shaped gaskets that are in close contact with the cylinder, and two ring-shaped gaskets that are in close contact with the upper cylinder of the inlet when water is flowing. This drain valve for preventing water hammer is formed by forming a small hole between the seals to form a passage for pressure water to the piston upper end chamber, and further forming a communication hole inside to connect the piston upper end chamber and the drain port.
