hydraulic automatic centrifugal pump outlet valve can be used, with the closure of the check
Brief: hydraulic automatic centrifugal pump outlet valve can be used, with the closure of the check, Kai pump light load, eliminate water hammer and flow adjustment and other functions, which can effectively protect the pump and pipeline safety equipment;
Technical Features
Small resistance: The valve control technology, valve plate to open high resistance, resistance coefficient 0.3-1.1;
Small size: butterfly valve body structure, size is only the same caliber multifunction water control valves
1 / 3-1 / 5;
Light weight: The weight is only multifunction water control valves 1 / 3-1 / 5;
Long life: the use of oblique seal width, having a sealing surface wear automatic compensation function, significantly extended service life;
Automatic Control: Valve and pump medium chain through the inner tube, valve linkage, without human intervention, a pump to open the valve open, pump stop valve closed;
Energy saving: the use of medium pressure drive, no external power, energy saving;
Good seal: double sealed using a combination of hardware and software technology to effectively solve the problem of large diameter valve seal, long-term to ensure that "0" leakage;
Open and close easily: Big valve plate with eccentric structure, the friction torque is small, open and close easily;
Easy maintenance: Control System components are external to the outside of the body, commissioning, easy maintenance, available online overhaul.
Slanting Check Valves are used on the outlet of the water pump of industrial water supply and sludge
treatment plant to prevent the medium inside the pipe network from going back, and remove
automatically the destructive water hammer so as to ensure both pump and pipeline not to get
damaged.
It consists of body, disc, buffer and micro-adjusting valve. And it features by the brand new structure,
small volume, small fluid resistance, reliable seal, wearable and good buffering performance.
It is really the best product for industrial use of water and city sludge drainage.
