Structural composition of Automatic urinary flush valve
Automatic urinary flush valve is composed of valve body, end cover, button mechanism, piston mechanism and other accessory parts. A hollow cylinder with two or more holes.
The manufacturer of Automatic urinary flush valve said that taking the foot-operated self-closing delayer as an example, the valve as a whole is composed of four major components, the maintenance valve, the connecting pipe, the flushing valve (main body), and the flushing port. The maintenance valve has a water switch adjustment screw for easy maintenance, and there is a pressurized water chamber and delay time adjustment screw on the flushing valve body. There is a spool that moves up and down in the valve body. The spool has two materials of cast copper and plastic. It is composed of a pressure relief rod, a water inlet, a booster pinhole, and an upper and lower sealing rubber ring. The manufacturer of Automatic urinary flush valve tells you that in the normal state, the lower rubber ring and the water pressure in the water cavity of the valve body plus the gravity of the valve core work together to seal the lower rubber ring and the water outlet to block the waterway, and the valve core is released after people step on the pedal. The pressure rod deviates from the axial center at an inclination angle of 3 to 5 degrees, and the flushing port communicates with the water cavity of the valve body. At this moment, the moment the static pressure on the upper part of the water cavity of the valve body is released, the pressure in the cavity is equal to the atmospheric pressure, and the pressure in the pipeline The water pressure pushes the valve core to move up, and the pipeline water communicates with the water outlet to form a large water flow to complete the flushing action. At the same time of flushing, the valve core moves up, the upper rubber ring of the valve core is sealed with the upper water chamber, and the pipeline water supplies water to the pressurized water chamber through the φ1mm pressurized water inlet needle hole behind the water inlet filter of the valve core, Automatic urinary flush valve The manufacturer tells you that as the water pressure in the upper water chamber increases, 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.
