Mobile Toilet Sewage Valve

Mobile toilet sewage valves mainly come in two types: automatic sewage valves and one-way check valves, with their working principles and characteristics as follows:

Automatic Sewage Valve

The automatic sewage valve is a relatively intelligent type of sewage valve in mobile toilets. It monitors key data such as pressure and flow rate in the pipeline through sensors. When these data exceed the preset standard range, the sensors promptly transmit signals to the control module. After receiving the signals, the control module directs the actuator to start working. The actuator pushes the valve core to move in stages. At the initial stage of valve opening, the valve core does not fully open but leaves a narrow gap first. The purpose of this is to perform pressure reduction operations to avoid damage to the pipeline and equipment due to excessive pressure. At the same time, the existence of the narrow gap allows dirt to be partially washed away with the water flow first, reducing the resistance during subsequent full opening. When most of the dirt has been washed away, the actuator further pushes the valve core to fully open it, ensuring that the waste can be smoothly discharged. When closing the valve, the valve core presses down, and at this time, the high-speed water flow plays a role again, washing away the impurities remaining around the valve core and in the pipeline. Finally, the valve core closes tightly to ensure a sealing effect, preventing sewage leakage and odor emission. This staged opening and closing design of the valve core effectively protects the sealing surface of the sewage valve and extends its service life.

One-Way Check Valve

The one-way check valve mainly serves to prevent sewage backflow in mobile toilets. It ensures that water flows in only one direction and is usually installed on the angle valve of the toilet. During the use of mobile toilets, various reasons may lead to sewage backflow, which not only affects the normal use of the toilet but may also cause hygiene problems. The presence of the one-way check valve, like a one-way door, only allows water to flow from the toilet to the sewage pipeline. When there is a tendency for sewage to flow back, the valve automatically closes to prevent sewage backflow, effectively solving the problem of toilet sewage backflow and ensuring the hygiene and safety of mobile toilets.

In addition, mobile toilets with different discharge methods, such as conventional water-flush toilets, vacuum sewage systems, and water-storage sewage systems, may have certain differences in the application and design of their sewage valves to adapt to their respective sewage characteristics.
