Emergency gas shut-off valve

Dateline:2014-11-30 Hits:

Gas emergency shut-off valve in the equipment failure, corrosion failure, seal failure,leakage, or emergency, to cut off the source of upstream hazardous materials, to avoid accident scope, control effects of the accident, reduce the loss of accidents.Emergency gas shut-off valve is a practical environmental protection type by Shanghai Yonglong valves factory \\ technology development department five retired senior engineer Zhang Gong invented the shut-off valve.

Emergency gas shut-off valve is arranged in the gas tank / piping exit emergencywhich can quickly cut off valve, the valve to control the use of the electromagnetic valve is closed, is one of the relatively ideal safety valve.

Product overview:

Emergency gas shut-off valve is normally open type pulse trigger type electromagnetic valve. Shanghai Yonglong valves production gas emergency shut-offvalve has the advantages of simple structure, sensitive response, reliable action,accident self-locking and manual reset function etc. it is used in all walks of life. Mainly in the following aspects:

1 and the leakage of combustible gas monitoring instrument is connected. When the instrument to detect combustible gas leak, close the main gas supply automatic fastvalve, cut off the supply of gas, time to stop the occurrence of malignant accidents.

2 and the limit temperature of thermal equipment (or pressure) is connected to the safety controller. When the numerical limit device is within the detection point temperature or pressure exceeds the set, automatically and quickly close the gas supply valve, stop fuel supply.

The central fire leakage instrument system 3 and tall buildings connected. When thebuilding when the fire occurs, automatic cut off the building's gas supply, to prevent accidents.

Emergency gas shut-off valve is arranged 4 or factories in the city gas supply pipe network, in the central control room centralized control, remote control, emergency shut off the scene of the accident of pipeline gas. Suitable for gas, natural gas andliquefied petroleum gas and other combustible gases, widely used in the gas supply pipeline network, gas heat energy factory, gas boiler room and the safety facilities ofthe residential housing.

5 reliable technical performance; low load loss; very high safety performance; energy saving excellent performance; rapid cutting performance are the five majorcharacteristics of the series products.
