Problems solved by technology
However, most of the existing two-position three-way solenoid valves use gas as the transmission medium. Due to the small diameter of the reversing part and different structures, they are not suitable for waterway reversing, and cannot be applied to the water booster device in the vacuum toilet.

The invention relates to an air control reversing water valve. The air control reversing water valve comprises a valve seat, a valve body, an upper end cover and a middle valve plug, wherein four interfaces, namely an air control interface, a normal pressure water interface, a supercharging water interface and a supercharging water outlet are arranged in the valve body; the passage between the normal pressure water interface and the supercharging water interface is provided with an upper-part sealing element; the passage between the supercharging water interface and the supercharging water outlet is provided with a lower-part sealing element; the middle valve plug is arranged in the center of the valve seat; the upper-part sealing element is sleeved on the upper part of the middle valve plug; the lower-part sealing element is sleeved on the lower part of the middle valve plug; a spring is arranged between the lower-part sealing element and the valve seat; the upper end cover is fixed to the valve body; the lower-part valve seat is fixed to the valve body; the upper-part sealing element is arranged in the air control interface and sealed to the valve body; the air control interface is connected with the control air source; and the control air source is used for controlling the sealing and opening of the passage between the normal pressure water interface and the supercharging water interface and the passage between the supercharging water interface and the supercharging water outlet. The invention also provides a water supercharging device of a vacuum toilet system.
Description
technical field [0001] The invention relates to an air-controlled reversing water valve, and applies the air-controlled reversing water valve to a water booster device of a vacuum toilet. Background technique [0002] Vacuum toilet is a dirt collection system widely used in my country's railway passenger vehicles at present. When designing a vacuum toilet, for the sake of saving water, the normal-pressure water provided by the train must be pressurized before flushing the bedpan. This method of flushing the bedpan with pressurized water can save water compared with the traditional normal-pressure water flushing method About 75%, greatly reducing the consumption of precious water sources on the car. [0003] The water booster device in the existing vacuum urinal is to change the normal pressure water into the pressure water, which is composed of a water booster and an air-controlled reversing water valve; the function of the water booster is to temporarily store it in its ca...
