Electric fully enclosed plate valve structure features and uses

Electric fully enclosed plate valve structure features and uses:

Fully enclosed electric valve plate closed design structure, the valve body with a fully enclosed shell, the operation of pipeline gas leaks, to avoid environmental pollution, with good resistance to external pipe strength, electro-hydraulic device Set to the outside, in order to maintain the inspection, personnel safety performance close operation, the disadvantage is the replacement of apron trouble.

The valve is designed to absorb the advantages of foreign floating valve plate floating valve; compression transmission mechanism used: ring gear, trapezoidal thread, screw synchronization two-way compression. The advantages of synchronous compression of the left and right screw thread trapezoidal thread are: small starting torque, good self-locking screw thread, reliable sealing of the valve, the plate movement using pin gear transmission mechanism, easy to fouling to meet the dust and lubrication conditions are poor , Work environment harsh occasions apply.

Electric closed flapper valve structure

Electric closed flapper valve structure features:

Flapper valve by the front valve body, after the valve body, valve plate, telescopic body, around the sealed box, through the board and the blind and the switching device, the release of clamping devices and other components. Metallurgical valve release clamping device driven by the electric device , through the sprocket, chain and screw nut connection, drive bellows telescopic to achieve the valve seal seat clamp or release. Valve chain wheel multi-point clamping mechanism, the seal is double-sided seal, mounted on the valve plate, sealed and reliable, easy to replace. The top rail of the valve plate is equipped with vertical and horizontal movement mechanism, spring mechanism and limit wheel on the side. When the clamping mechanism is released to release the valve plate, the spring mechanism pulls the valve plate to the limit wheel.
