Rectangular Explosion Relief Valve

 Rectangular Explosion Relief Valve

The LFBtype vent valve is used to bear the pressure gas pipeline,and the container equipment and the system play an instantaneous pressurerelief function. The safety operation of production can be ensured, andaccidents caused by overpressure explosion can be prevented, so as to eliminatethe damage to the pipeline and the equipment. And is a safety device requiredby the symbol "Safety Supervision Regulation for Pressure Vessels".For explosion calculation pressure (absolute) <0.76 mpa

The LFB valveconsists of a box and an explosion-proof door. When the system pressure exceedsthe design pressure, the explosion-proof door opens itself to release pressureand prevent the system from exploding. The explosion - proof door automaticallyreturns to position under the action of heavy hammer.

Theself-closing gas safety release valve produced by our factory has the shortpipe of the valve body with flange, connected by the screw and the supportring, the screw has the sliding valve stem, and the support ring has thepressure limit reset spring sleeve of the first or multi-stage valve cover,which overcomes the shortcomings of the open type after the explosion of theexplosion vane or the heavy thallium type explosion valve, that is, theexternal air can enter the gas equipment and pipe, resulting in the second bigexplosion, It has the function of automatic explosion release and automaticclosure, suitable for the working environment of gas and air pipeline,reasonable structure, safe operation, reliability, convenient use, saving fundsand suitable for the needs of modern industry.
