Products Description

JD745X-10Q Multifunctional water pump control valve is composed of the main valve and regulating valve and take over the system, the main valve body adopts once-through body control room for the diaphragm or piston type double control room design, hydraulic control valve added a control room, strengthen the function of the control of the main valve, realized with the pump export slowly open, open, closed, as of multi-function control, The multifunctional control of one valve and one adjustment to the pump outlet is realized.

The valve is installed at the outlet end of the water pump, realizing the functions of slow opening, full opening, fast closing and slow closing in sequence.

JD745X-16Q multifunctional water pump control valve control system using control valve control, by setting the opening of the control valve, it can be convenient to achieve the required control parameters, such as the main valve opening speed, slow closing speed and so on.

Mainly used for high-rise building water supply system and other water supply system pump outlet pipe, to prevent and weaken the water hammer water strike pipeline when the pump open and close, to prevent water flow back to protect the pump, maintain pipeline safety.

Main features

1. High safety and reliability. It has three measures to eliminate water hammer, namely quick closing, slow closing and energy absorbing cavity, and the actions are completely interlocked without malfunction.

2. No operation control is required. When the pump starts and stops, the medium at both ends of the valve and its pressure difference are cleverly used as the driving medium and control power, so that the valve can automatically act according to the requirements of the pump operating procedures.

3. No professional debugging is required. The valve action is not affected by the liquid level height difference, the water outlet pressure and the change of the water pump flow rate, and has a wide range of adaptability.
4. Basically no maintenance is required, and the service life is long.

5. The energy saving effect is obvious. The pressure at the inlet end is used to enter the lower cavity to support the weight of the diaphragm pressure plate and the valve stem, and the resistance loss is small.

6. The effect of preventing water hammer is good. It integrates the technologies of slow opening, quick closing, slow closing, etc. to eliminate water hammer, so as to prevent the damage to the water supply pipeline and water pump caused by the pump without hammering, the reverse flow of the pump when the pump is stopped, and the water hammer.
