Before installing the multifunctional water pump control valve, we need to check whether the main valve is in good condition, the fasteners should not be loose, and the accessories are complete. So everyone knows how to adjust the multifunctional water pump control valve?
The working principle of the installation and commissioning of the multifunctional water pump control valve is as follows:
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 pressure in the main valve control chamber keeps the main valve at a proper opening and maintains 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 pressure in the control room 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.
The valve body of the multi-function water pump control valve adopts a full-channel, streamlined design, with small fluid resistance and large flow. Adopting foreign advanced technology of detachable valve seat, ingenious structure, easy maintenance and replacement
