[Essential information]

Multifunctional pump control valve from the main valve and the valve body and take over the system components, DC type valve, the main valve control room control room for double diaphragm or piston structure, the control room than the average increase of the hydraulic control valve a, increases the control function of the main valve, the water pump outlet slowly open, open, slow closing, closing and other multi-functional control, achieved the function of a valve, a regulator on the pump export control.

The control system of the multi-function pump control valve adopts the control valve. By setting the opening of the regulating valve, various control parameters can be conveniently realized, such as the opening speed of the main valve, the speed of slow closing and so on. When the water pump starts, the water pressure acts on the main valve, the valve plate and the lower chamber of the control chamber. This pressure causes the main valve to be opened. The water in the upper chamber of the control chamber is slowly discharged to the outlet through the regulating valve B, and the main valve is opened slowly. Setting the opening of the regulating valve, you can get the proper opening speed of the main valve. When the pump stops working after the inlet pressure decreases rapidly, quickly shut down most of opening under the action of self weight, spring pressure, prevent water backflow opening remaining from the control room on cavity pressure and water pressure of the lower cavity under the combined effect of slowly closing, slowing the closing speed of forming a buffer, to prevent the pressure surge.

[Valve features]
1, A, B set the valve opening and the opening ratio of the right valve opening and closing speed. To prevent water hammer good, will slow open, check back, fast closing, slow closing and so on to eliminate water hammer technical integration, to prevent the pump does not hammer and stop pumping back and water hammer on the water supply pipeline and pump damage.

2, easy to operate, no need for the valve with electrical control system, the valve with the pump on and off, automatically and sequentially complete control functions. The proper control parameters can be obtained by setting the opening of the regulating valve.

3 、 the valve body adopts full passage, direct current and streamline design. The utility model has the advantages of small hydraulic loss and good energy saving effect. The valve is installed at the outlet of the water pump, in order to realize the functions of slow opening, full opening, quick closing, slow closing and so on.
