Claims

[Scope of utility model registration request]

It reciprocates within the valve box, which forms a drain in addition to the inlet and outlet, and when pressure water acts on the pressure-receiving surface, it sits on the valve seat, stops water, and becomes drained, reducing the working pressure on the pressure-receiving surface. a main valve that separates from the valve seat to open the flow path and enter the water supply state when the pressure reaches atmospheric pressure;
a pilot valve that is provided separately from the main valve and opens and closes a working port for pressure water acting on the pressure receiving surface of the main valve; and a pilot valve that is housed in an operating valve box that is connected to the valve box through an outer jacket pipe In a water drain valve in which the main valve responds automatically by water pressure by a solenoid and an iron core therein that respond by magnetic force when energized, the pilot valve has an upper end connected to a shaft, and an upper end of the shaft is connected to the iron core. The rod is pressed from one side to the other by a spring supported at one end, and two pins are installed vertically to the rod axis at approximately the center of the rod with a gap between them. A cylindrical rotating rod support with a flange provided in the gap is rotatably provided on the rod, inclined surfaces are provided at equal intervals on the upper and lower end surfaces of the rotating rod support, and the pilot is attached to the bottom of the inclined surface at one end. A pilot valve type solenoid drain valve characterized by having grooves equal to the stroke of the valve every other time.
