Piston pipe valve working principle and characteristics

Piston pipe valve Product Overview:

Piston pipe valve is the latest export control valve, is following the old manual control valve, hydraulic butterfly valve, hydraulic control valve after the third-generation new butterfly multi-function water pump control valve, is the most advanced structure at home and abroad, the most performance Advanced, the most reliable operation of the new pumping station control equipment. Piston pipe valve for centrifugal pump, vacuum pump, mixed flow pump and axial flow pump outlet pipe, designed with diaphragm and piston two kinds of control devices, respectively, for water, raw water media and Sewage, slurry water medium. Product types, the development of common type, backwater low pressure type, sewage and other five specifications to meet the needs of different conditions.

Piston pipe valve Features:

Piston pipe valve adopts advanced fluid design, compact structure, small size, light weight, low energy consumption, stable operation, good sealing effect, and both electric gate valve, electric butterfly valve and check valve function, with quick agility Off speed and adjustable pressure relief time, can effectively eliminate the hazards of water hammer to protect the pump and pipe network System security.

Piston pipe valve works:

Piston pipe valve mainly by the valve body, a large flap, a small flap, stem, adjusting rod, master cylinder, bypass valve, spring, slowly closed piston and other components. Valve opening and closing driven by the transmission medium, automatic interlocking with the pump, without external personnel operations. When the pump starts, the water pressure through the inlet bypass pipe into the control of the lower chamber, the large valve under the action of the medium in the import, together with the small flap slowly open, open the valve speed can be adjusted according to operating conditions. When the pump is closed, the valve into the product medium pressure loss, large flap in the self-action automatically shut down, cut off 70-80% of the flow medium, at the same time, part of the return flow through the bypass valve into the control cylinder chamber, Lever down, close the flap to completely cut off the media. Off time can be achieved by bypass valve adjustment, the water hammer peak control within the specified range.

Piston pipe valve Scope of application:

Piston pipe valve has the advantages of compact structure, small volume and light weight. It is especially suitable for large-diameter pipe network system. It can be widely used in electric power, environmental protection, metallurgy, petrochemical, water division, municipal and food industries, drainage system, sewage pump Room, chemical fluids and other industries pressurized water supply system output of the pump at the exit.
