Brief introduction of multifunctional water pump control valve
Multifunctional water pump control valve is a new type of hydraulic control valve, one valve can replace the electric butterfly (gate) valve, check valve and water hammer eliminator three devices. The utility model can automatically realize the slow opening when the pump is opened, the quick closing and the slow closing when the pump is stopped, without any electric control, other power and manpower, and no oil pressure device.
The main advantages of multifunctional water pump control valve
(1) no operation control is necessary. Use of water pump start and stop when the valve before and after the water pressure difference as the control power, with the water pump opening and closing automatically open and close function.
(2) the valve opening and closing process can effectively prevent accidents caused by the rising of water hammer pressure wave. According to field investigation and measurement, the peak value of the water hammer in the pump is less than 1.3 times the working pressure.
(3) no field debugging, wide range of working conditions.
(4) basically no maintenance required. As a valve instead of three valves, maintenance and maintenance work greatly reduced.
(5) resistance loss is small. With streamlined, wide body design, the resistance loss is more than 50% lower than similar foreign products, such as DN200 products in the v=2m / s flow rate of economic conditions, multi-functional water pump control valve loss of 0.7m, and similar foreign products for 1.5m.
Structure and working principle of multifunctional water pump control valve
1) before the pump starts, the pressure at the outlet of the valve acts on the main valve plate, and the valve is in the closed position. At the same time, the upper chamber of the diaphragm controller communicates with the pressure water, and the lower chamber is communicated with the low voltage at the inlet of the valve.
2), pump starts, valve inlet pressure gradually increased, while the pressure of water through the valve inlet connection tube slowly into the diaphragm controller vena, slow realization of the main valve plate opening, opening speed can be adjusted through the control valve.
3) the pump stops and the pressure on the inlet of the valve is lowered. When approaching zero flow, the main valve plate closes rapidly under the influence of its own gravity. Valve inlet pressure is reduced due to the valve outlet pressure water through the connecting pipe into diaphragm chamber controller, inferior vena water through the valve inlet connection pipe pressure back to the inlet valves, slow closing valve plate slowly closed off time can be slow through the control valve. The fast closing of the main valve plate and the closing and closing of the closed valve plate are in accordance with the two stage closing law, which can effectively eliminate the water hammer.
