Multifunctional water pump control valve can be used in chemical, petrochemical, petroleum, papermaking, mining, pharmaceutical, water supply and drainage, municipal administration, mechanical equipment supporting, electronic industry, urban construction and other fields. So everyone knows what are the principles and characteristics of the multifunctional water pump control valve?
The principle of multifunctional water pump control valve:
When the working valve of the water pump supplies water downstream, the solenoid pilot valve is fully opened and the needle valve is adjusted to a proper opening. The upstream water enters the main valve control room through the needle valve and the one-way valve, and flows out through the solenoid pilot valve. At this time, the main valve control room The pressure keeps the main valve at a proper opening and maintains the normal water supply downstream. When the water pump stops working, the solenoid pilot valve is closed first, the main valve control room stops draining, the control room pressure rises, and the main valve starts to close. When it is closed to 90%, the upper stroke switch of the main valve outputs a pump stop signal and the water pump stops running. At this time, the downstream backwater enters the main valve control room through the one-way valve, the pressure in the control room rises, and the main valve is closed.
Features of multifunctional water pump control valve:
1. The valve body adopts a full-channel, direct-flow and streamlined design. The hydraulic loss is small and the energy saving effect is good.
2. Easy to operate, no need to add a power distribution control system for the valve, the valve will automatically complete the control function in sequence with the opening and stopping of the water pump. Appropriate control parameters can be obtained by setting the opening of the regulating valve.
3. The effect of preventing water hammer is good, integrating the technology of eliminating water hammer such as slow opening, non-return quick closing, slow closing, etc., to prevent the damage to the water supply pipeline and the water pump due to the failure of the pump, the backflow and the water hammer.
The multifunctional water pump control valve is used to install on the pump outlet pipe of the water supply system of high-rise buildings and other water supply systems. Prevent the medium from flowing back and prevent the occurrence of water hammer and water hammer.
The principle and characteristics of the multifunctional water pump control valve are mainly the ones introduced above. We should all understand the principle and characteristics of our valve now. I hope everyone needs the correct method to operate and use.
