1, the reliability of eliminating water hammer is high. The opening and closing of the slow closing device are interlocked with the main penalty board; Automatically realize fast closing, which is not affected by the fluctuation of actual pump flow and head, and does not need to calculate fast closing time; There is no need for on-site adjustment by professional technicians; There is no need for electrical appliances and oil pressure components, and there are few fault points.
2, the effect of eliminating water hammer is good. Three technical principles of fast closing, slow closing and water hammer absorber are integrated, so that the water hammer pressure is reduced to the minimum when the pump is stopped.
3. The valve is easy to operate and maintain. Just operate the start-stop button of the water pump motor starter, and the valve will automatically open and close according to the operation law of the water pump. The key parts are made of high-quality materials, which basically do not need maintenance.
4. Good energy-saving effect. Adopting streamlined and flexible valve body and the latest patented technology design, compared with imported similar products, the resistance loss is reduced by more than 50%.
Introduction:
The water pump control valve is a valve controlled by water pressure. The control valve of water pump is composed of main valve and its auxiliary conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose, function and place of use, it can evolve into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure reducing valve, hydraulic electric control valve, water pump control valve, etc. Generally, this valve should be installed horizontally in the pipeline.
