Functional Description of Zoomlion Hubei Chengl Li 5160TXS Pneumatic Shut-Off Valve (EQ22-50, for Dongfeng Tianjin Sanitation Vehicles)
This pneumatic shut-off valve is a core control component specifically designed for Dongfeng Tianjin sanitation vehicles (sweeper-scrubber trucks, sprinkler trucks, etc.), focusing on three core requirements: "precise fluid control, durable adaptation, and safety & reliability". Its specific functions are as follows:
1.Intelligent On-Off & Pressure Regulation: Driven by pneumatics, it can quickly turn the water circuit on/off with a response time of ≤0.5 seconds. It has a built-in pressure balance structure, adapting to a working pressure range of 0.2-1.0MPa, which can automatically cope with water pressure fluctuations and prevent pipeline damage. It also supports manual emergency operation—when the pneumatic system fails, the valve can be manually opened/closed via an eccentric shaft to ensure basic operations.
2.Durable Adaptation for Sanitation Scenarios: The valve body is made of stainless steel (304/316L) with an anti-corrosion coating on the surface, improving resistance to sewage and acid-base corrosion by more than 5 times, with a service life of up to 8000 hours. The valve seat adopts a hard-seal structure (hard alloy overlay welding), which can withstand the erosion of sediment-containing water flow, with a leakage rate of ≤0.01% of the rated flow. It supports two modes: high-pressure cleaning (full opening with a flow rate of 80m³/h, suitable for road flushing) and spray dust suppression (atomization particle size ≤50μm, suitable for dust control), meeting cleaning needs in multiple scenarios.
3.Safety Protection & Low Maintenance: Equipped with a limit switch, it provides real-time feedback on the valve's on-off status to prevent misoperation. It uses a double-acting spring-return pneumatic actuator—when the air supply is interrupted, the valve closes automatically to avoid water loss or pipeline burst. It has a built-in self-cleaning function, which purges the valve cavity through reverse air flow to reduce impurity deposition. The modular design allows quick separation of the valve body and actuator; maintenance does not require pipeline disassembly, shortening maintenance time by 60%.
