Before installing the multifunctional water pump control valve, check whether the main valve is in good condition and whether the accessories are complete. Then, Fang Gong believed that the installation should be carried out according to the installation drawing of the multifunctional water pump control valve. So everyone knows what are the basic functions of the multifunctional water pump control valve?
The basic functions of the multifunctional water pump control valve are as follows:
1. The function of the gate valve
The gate valve is usually closed. When the water pump starts, the gate valve opens slowly, and when the water pump stops, it slowly closes to a certain extent. The closed start and closed stop of the water pump can effectively prevent the water hammer when the pump is opened and the water hammer when the pump is stopped, and reduces the motor load when the pump is started. The shaft power of the pump at zero flow is the smallest, which is generally only the design shaft power. 30%.
2. The function of water hammer eliminator
The water hammer eliminator can effectively eliminate the irregular water hammer shock caused by various types of fluids in the transmission system that may be generated by the water hammer and surges, so as to eliminate the destructive shock waves. Play the purpose of protection.
3. The function of the check valve
The check valve can prevent the change of the flow direction of the water caused by the sudden power failure and prevent backflow. The sudden closing of the check valve is prone to water hammer. When the geometric pumping height of the water pump is large, severe water hammer instantaneous high pressure will cause the pipeline to rupture.
The multifunctional water pump control valve is installed on the pump outlet pipe of the water supply system of high-rise buildings and other water supply systems. Prevent quality backflow and prevent water hammer and water hammer.
The basic functions of the multifunctional water pump control valve are mainly those described above. We should all need to understand the function of our valve. The correct way to operate and use our valve is what we need.
