Drain valve for full-automatic toilet flushing device
The invention discloses a drain valve for a full-automatic toilet flushing device. The drain valve comprises a water tank, a valve seat and a valve cover, wherein the valve seat is arranged in the water tank, the valve cover covers the valve seat, a water outlet is formed in the bottom of the valve seat, a valve is arranged at the water outlet, a valve cavity is formed in the valve cover, a piston is arranged in the valve cavity, a tap water outlet is formed in the middle of the bottom of the valve cavity, a tap water outlet valve is arranged at the tap water outlet, the center of the valve is fixedly connected with the center of the piston through a pull rod, the tap water outlet valve is connected to the pull rod in series, the pull rod passes through the center of the tap water outlet valve, a tap water inlet is formed in the valve cover, and the tap water inlet is communicated with the valve cavity. Compared with other valves, the drain valve has the advantages of simple production process, low cost, less consumed materials and small size; the transportation cost can be saved by 40 to 50%, the quality can be guaranteed, the starting power is about 4 watts, and the service life is long because a control solenoid valve is not in water.
