The manufacturer of Pedal and sensor toilet flush valve tells you that the whole valve is composed of four parts: 1. Maintenance valve; 2. Connection pipe; 3. Flush valve (main body); 4. Flush port.
Pedal and sensor toilet flush valve manufacturers tell you that the maintenance valve has a water switch adjustment screw for easy maintenance, and the flush valve body has a pressurized water chamber and a delay time adjustment screw. There is a valve core that moves up and down in the valve body. The valve core is made of cast copper and plastic. It consists of a pressure relief rod, a water inlet, a booster pinhole, and an upper and lower sealing rubber ring. The manufacturer of Pedal and sensor toilet flush valve tells you that under normal conditions, the lower rubber ring and the water pressure in the valve body water cavity and the gravity of the valve core work together to seal the lower rubber ring and the water outlet to block the waterway. The pressure relief rod of the core deviates from the inclination angle of 3 to 5 degrees from the axis, and the flushing port is connected to the water cavity of the valve body. The water pressure in the pipeline pushes the valve core upward, and the water in the pipeline communicates with the water outlet to form a large water flow and complete the flushing action.
The manufacturer of Pedal and sensor toilet flush valve tells you that when flushing, the valve core moves up, the rubber ring on the valve core is sealed with the upper water chamber, and the pipe water passes through the φ1mm pressurized water inlet needle hole after the filter screen of the valve core water inlet to increase. The pressure water chamber supplies water. With the increase of water pressure in the upper water chamber, the valve core is forced to move down, and the rubber ring under the valve core seals the water outlet to achieve the purpose of delay.
