[0002] The exhaust and air supply valve is a valve with automatic exhaust and air supply functions. It is mainly used to protect the pipeline from pressure damage and improve the discharge efficiency of the water supply pipeline. It usually adopts a double air port design, and a small hole exhaust valve is installed on the right side. It can quickly introduce outside air when negative pressure is generated in the pipeline to protect the pipeline. At present, during the use of the exhaust and air supply valve, a pressure sensor is usually used to perform intelligent safety monitoring on whether there is negative pressure in the pipeline, so that personnel can judge whether the exhaust and air supply valve can work normally. Since the pressure sensor is usually installed and fixed with bolts during the connection between the pressure sensor and the pipeline, when the pressure sensor is damaged and needs to be replaced in the later stage, it is often necessary to use tools to disassemble it. The operation is relatively cumbersome, which brings certain inconveniences to the maintenance work of the personnel. Utility Model Content
