Knowledge of water pump control valve
The water pump control valve is the valve for water pressure control. The water pump control valve consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose of use, function and location, it can evolve into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc. This type of valve should generally be installed horizontally in the pipeline.
A filter should be installed before the water pump control valve, and it should be easy to drain. There are generally two types of water pump control valves. Their work is the same. They all have a main control valve to control all equipment. These two types of valves are mainly divided into piston type and diaphragm type. The two of them are used in conjunction.
The working principles of the two types of valves, piston type and diaphragm type, are also similar. The switch is mainly controlled by pressure. While controlling, the dual-mode plate is used for control first, and then the valve body screw outside the control valve body.
The valve is not only used in conjunction with the pipeline, but also often used in conjunction with the water pump, especially when the water pump is turned on, a large amount of pressure is generated inside, which can directly push the valve to open, and then start the valve console . The safety of this kind of valve is relatively high, especially the control performance. Generally, there is no need to manually operate the console. You can directly use the opening and closing device on the valve body to control after opening the pump, and the opening and closing speeds are very high.
