Flush valve structure description The valve body, the end cover, the button mechanism, the piston mechanism and other accessory components are characterized in that the top end of the plunger valve in the piston mechanism of the flush valve is a curved guide column, and the accelerator is processed by a side wall of two or Hollow cylinder of two or more perforations. Take the pedal self-closing delay device as an example; the whole valve is composed of four major components: 1 maintenance valve; 2 connecting pipe; 3 flushing valve (main body); 4 flushing port. The service valve has a water switch adjustment screw for easy maintenance. The flush valve body has a pressurized water chamber and a time delay adjustment screw. The valve body has a valve core that moves up and down. The valve core has two materials, cast copper and plastic. It consists of a pressure relief rod, a water inlet, a pressurized pinhole, and a top and bottom sealing rubber ring. In the normal state, the lower apron and the water pressure in the valve body water chamber plus the gravity of the valve core work together to seal the water passage between the lower rubber ring and the water outlet, and the pressure relief rod of the valve core is deviated from the axial center after the foot pedal is pressed. At a 5 degree inclination angle, the flushing port is in communication with the valve body water chamber. At this moment, when the static pressure in the upper part of the valve body water chamber is released, the pressure in the chamber is equal to the atmospheric pressure, and the water pressure in the pipe pushes the spool upward. The pipeline water communicates with the water outlet to form a larger water flow and complete the flushing action. At the same time of flushing, the valve core moves up, the apron on the valve core is sealed with the upper water chamber, and the pipe water is supplied to the pressurized water chamber through the φ1 mm pressurized water inlet pinhole after the spool inlet filter, with the water supply The increase of the water pressure in the cavity forces the spool to move down, and the lower apron of the spool seals the water outlet to achieve the purpose of delay.
