The automatic control and light-load starting pump is affected by the pressure of the control room. When the water pump is started, the main valve is slowly opened, so that the load of the water pump with excessive flow is controlled,and the water hammer of the open pump is eliminated.
The safety and reliability is high, the elimination water hammer device is completely linked to the valve opening and closing action, at the same time, it has three kinds of measures to eliminate the water hammer: quick closing, slow closing and absorbing three kinds of measures to eliminate the water hammer.
The operation control is not required, and when the water pump is started and stopped, the medium and the pressure difference between the two ends of the valve are used as the driving medium and the control power, so that the valve can automatically operate according to the operating procedures of the water pump.
No professional debugging is required, the operation of the valve is not affected by the level difference of the liquid level and the change of the water outlet pressure and the flow of the water pump, and the application range is wide.
The energy saving effect is remarkable, the weight of the diaphragm and valve plate is supported by the pressure at the inlet end, and the resistance loss is small.
The maintenance is convenient, the life is long, and this valve basically does not need to repair. When special circumstances, upper cover, film seat, stem,valve plate can be taken out, easy to repair and replace rubber seal ring, o -ring and other vulnerable parts.
The multi functional hydraulic control valve is mainly installed in the water supply and drainage, building, petroleum, chemical, gas,natural gas, food, medicine, power station, nuclear power and other fields of water taking, water supply, clean water, sewage, pump house and petro chemical fluid conveying system, The outlet or other piping system connected to the pump is used as the contro
