What is the qualitative difference between the multifunctional water pump control valve and the traditional gate valve, butterfly valve, check valve, and constant-speed, two-speed slow closing hydraulic control check valve in terms of principle and function.
The main feature of the multifunctional water pump control valve structure is that the positioning mechanism in the middle of the valve seat and the spring on the upper side of the valve disc are eliminated, and a deflector is designed on the lower side of the valve disc, which limits the reduction of mechanical losses and mechanical losses when the medium flows. The vortex loss in the dome under the disc. The piston in the cylinder is used as the driving element to drive the valve flap to move up and down under the pressure of the medium itself to realize the opening or closing of the valve.
The working principle of the multi-function water pump control valve to meet the full-open valve start of the axial flow pump is the reverse operation of the centrifugal pump closing valve start, that is, the solenoid valve works first, and the water pump starts again after the valve is fully opened.
The multifunctional water pump control valve is a servo system composed of a solenoid valve reversing mechanism and a pressure pipeline. The pressure water at both ends of the control valve is used as the driving source. The pressure water at either end can realize the water pump control valve execution at the set time and speed. The opening or closing of the water pump.
