Embodiment Construction

[0006] A PVC pipe with a diameter of 48mm, a wall thickness of 3mm, and a height of 450mm is used as the valve core, a sealing rubber ring is embedded in the bottom edge, and a plastic operating handle is hinged on the top. The top of the gantry-shaped PVC bracket has a hole φ50mm, and the bottom of the bracket is in the shape of a round tube with external threads. The whole bracket is closed on the flush valve installation port of the toilet tank with an annular plastic nut. The spool is vertically inserted into the φ50mm opening on the top of the bracket, and the hinged handle on the upper part of the spool passes through the upper cover of the toilet tank for easy operation.

Abstract

The invention relates to a flashing valve which can be manually controlled to be closed at any time and can be applied to a water tank of a closestool. The flashing valve is fast closed by the gravity of a valve case or the elastic force. As the flashing valve can be fast closed, water in the water tank is guaranteed not to be thoroughly discharged at one time, thereby realizing the effect of water saving. The flashing valve can be applied to the production of a water saving closestool which nearly does not consume fresh running water.

Description

Technical field [0001] The invention relates to a sanitary appliance, in particular to a water closet flushing valve used in a toilet. Background technique [0002] At present, the known water closet flushing valve is made up of valve body and control mechanism, is installed in the toilet water tank. When the user operates the control mechanism, the flushing valve is opened to start flushing, and the flushing valve is automatically closed after the flushing is completed. However, such a flush valve cannot be closed at any time under human control when it is normally opened. It cannot be closed until the water in the water tank is basically emptied and the valve core overcomes the buoyancy of the water and falls automatically. Thereby, can't be applied in the novel relay type water-saving system. This relay-type water-saving system requires the use of a flush valve that can be closed at any time to ensure that the water in the water tank is not emptied all at once. The rel...
