Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire extinguishers, and in particular relates to a fire extinguisher valve and a fire extinguisher. Background Art
[0002] The management of portable fire extinguishers is still in a relatively backward way: check the fire extinguishers regularly (mostly once a month), mainly by the fire management personnel alone. The main inspection items: check whether the pressure gauge of the fire extinguisher is leaking (directly affects the fire extinguishing function). General inspection items: check the appearance and accessories of the fire extinguisher. Work records: record on the paper card outside the fire extinguisher.
[0003] This has led to some related problems: Fire extinguishers are stored at high pressure, and there are many factors that may cause leakage (failure of the sealing ring, failure of the switch seal, failure of the pressure gauge and its connecting threads, tank welding defects, corrosion of the tank itself, etc.). Once leakage begins, if the leakage rate is fast, it will generally not last until the next inspection cycle. In addition, most inspections are done by a single person, and the work quality cannot be reviewed. The cycle for replacing the fire extinguishing agent and the scrapping cycle are different depending on the environment in which the fire extinguisher is used. The resulting management work is actually quite complicated.
[0004] In particular, the pressure situation on the scene cannot be uniformly warned on a platform. In real life, when a sudden vehicle fire occurred, the fire extinguisher was used but it was found that the air leakage pressure was insufficient and the fire could not be extinguished, causing losses to people's lives and property safety, which is unacceptable at the social level.
[0005] The uncertainty of fire extinguisher leakage makes the regular inspection mode unmatched. How to detect fire extinguisher leakage in a timely and effective manner is a potential fire safety hazard that needs to be solved urgently.
[0006] There is a lack of a unified communication management platform for the early warning mechanism and effectiveness of portable fire extinguishers between the multi-level management departments between grassroots fire wardens and top-level fire management responsible persons, and between fire responsible departments and fire supervision departments.
[0007] Due to the large number of portable fire extinguishers (including trolley-type ones), they are widely used, such as mobile vehicles such as public transportation, tourism, passenger transportation, trucks, school buses, trains, motor vehicles, high-speed railways, subways, light rails, airplanes, ships, private cars, passenger cars, engineering machinery, special vehicles, etc., and fixed fire-fighting places such as bus stations, railway stations, subway stations, office buildings, gas stations, parking lots, airports, docks, factories, warehouses, KTVs, government agencies, religious places, hotels, supermarkets, schools, hospitals, cinemas, exhibition halls, communities, scenic spots, etc. When the base number is relatively large, the total number of leaking fire extinguishers will inevitably increase, and the hidden dangers of fire extinguishing effectiveness will increase.
