[0002] During the process of water plants adopting conventional water purification treatment processes, filter tanks are generally used. The pneumatic control system in a water plant is the core part of the filter tank process control, controlling multiple filter tanks. Each filter tank has 5 valves (inlet, drain, air washing, water washing, outlet regulation), and a total of multiple pneumatic valves are configured on the pneumatic pipeline. Generally, three air compressors work in turn and operate in an online cycle. However, the air pressure in the pneumatic system often leaks, resulting in frequent startup of the air compressor, high power consumption, easy damage and aging of mechanical parts, and high failure rate. At the same time, due to continuous pressure on the pneumatic pipeline, the pipeline life is shortened, the maintenance and purchase cycle of the pneumatic valve assembly is long, and the cost is high, which is not conducive to the operation of the water plant. Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to improve the prior art. Content of the Utility Model
