Device.
Background technology
Liquefied petroleum gas both belongs to hazardous chemical, and is connected closely with huge numbers of families, and its safe handling is related to society
Safety is harmonious.At present, the valve on existing liquefied gas steel cylinder generally uses the simple angle valve of stream, in liquefied gas steel
During the use of bottle, because angle valve generally opens and closes source of the gas using cock-type mode, angle valve position is likely to occur：1st, pacify
Fill the encapsulant aging of angle valve or loosen and cause the silk of angle valve and steel cylinder to connect position to leak air；2nd, angle valve inner sealing rubber cushion
Aging, corrosion cause gas leakage；3rd, steel cylinder need to often be moved in transportation is easily caused angle valve position to leak by damage
Gas.Because liquefied petroleum gas is flammable explosive gas, and it is heavier than air, easily accumulation, so when cylinder angle valve is leaked
Such as deal with improperly and very likely occur fire or explosion accident, cause any property loss or casualties.
The region people for not laying pipe natural gas locally in city widely use liquefied petroleum gas steel cylinder（Such as villages within the city
Deng）, these regions often floor, crowded, when cylinder angle valve position occurs that leakage is existing to lack effective leak stopping means, and
If can not leak stopping in time easily cause crowd panic, the complexity of site environment in addition, it is most likely that occur fire or blast thing
Therefore.Therefore, be highly desirable to develop it is a kind of can quickly handle the device for plugging of angle valve position leakage, leaked in angle valve
In the case of, the leakage of angle valve can be safely and reliably prevented, be pacified so as to there is the time that the steel cylinder of leakage is sent to filling station
Full processing, it is to avoid the generation of the accident such as burning, blast that leakage is likely to result in.
Under prior art scenario, the leak stoppage tool rushed to repair for oil and gas pipeline has many types, but for valve
The leak stoppage tool of door is seldom, less specifically designed for the angle valve device for plugging of cylinder for liquefied gas, wherein with present principles and structure and originally
