Hydraulic control intelligent check valve (energy storage tank type)
It is widely used in water conservancy, thermoelectricity, water supply and drainage, chemical industry, metallurgy and other pump stations. It is mainly installed at the outlet of the water pump and has the function of check valve and gate valve. During operation, the valve shall cooperate with the water pump. According to the preset procedure, the valve shall be closed in two stages: quick closing and slow closing, which can effectively eliminate and suppress the water hammer in the pipeline. It is an ideal equipment for safe travel of the pump unit and the pipe network system.
