The waterproof hammer air valve has the functions of low-pressure exhaust and high-pressure micro-exhaust of ordinary air valves. It is suitable for the working conditions where the pipeline trend fluctuates greatly, the system starts and stops frequently, and it is easy to cause flow interruption to bridge the water hammer and water column separation. When the water column separation pipeline is about to generate negative pressure, quickly exhaust a large amount of gas to avoid negative pressure. When water jet bridging occurs afterwards, the valve effectively limits the exhaust by delaying the exhaust time, creating an elastic compression space like an air sac in the pipe, preventing the pressure increase that may be caused by rapid water jet bridging.
