Description
Technical field
The present invention relates to a kind of leak-proof safe gas ball valve.
Background technique
Along with the growing tension of world energy supplies, the continuous enhancing of people's environmental consciousness, now each state all advocates energetically and uses that this amount of containing of combustion gas is enriched, had a high potential, the energy of clean environment firendly, but because various security incidents such as the gas leakage that the use combustion gas causes, poisoning, fire, blast are also increasing.Gas valve is that combustion gas is requisite when popularize using, at present nearly all gas valve particularly the small gas valve all only have ventilation, die, the function of control gaseous flow size.Although also occurred the gas valve that sub-fraction has certain protection function in the market, but these valves also exist structural design too complicated, if any introducing solenoid valve, the gas leakage inductor, need the additional power supply supply, will not lose all protection functions in case had electricity, what have designs protection function spare in valve metal control ball inside, because the Metal Ball inner space is original just very little, protection function spare is designed here the face performance of not only ensuring public security to be subjected to certain influence, but also the air-tightness can influence valve and cut off source of the gas the time, so there is the product structure complexity in prior art, security personnel's performance is not high, use inconvenient, many drawbacks such as reliability is low.
Summary of the invention
For overcome general gas valve mechanism complexity in the prior art, security personnel's performance not high, use the problem inconvenient, that reliability is low, the invention provides a kind of leak-proof safe gas ball valve, this leak-proof safe gas ball valve simple and compact for structure, reset operation convenient, safe and reliable, the effect that has energy-saving and environmental protection concurrently.
The technical solution adopted for the present invention to solve the technical problems is: comprise valve body, the ball core, valve rod and handle, two ends of valve body is respectively equipped with suction tude and steam outlet pipe, handle drives ball core Spin Control combustion gas break-make by valve rod, security personnel's resetting-mechanism is set in suction tude, security personnel's resetting-mechanism comprises Sealing, slide bar and positioning seat, slide bar is movably arranged in the positioning seat, Sealing be fixed on slide bar one end and with Sealing and ball core between the suction tude inwall on the sealing surface that forms match, magnet is set on the Sealing, and magnet matches with magnetic patch on being arranged on the ball core.
Under the ball valve closed condition, the magnetic patch on magnet on the Sealing and the ball core repels each other.
Slide bar overcoat security personnel spring, the two ends of security personnel's spring lean respectively on the back seat of positioning seat and slide bar.
The present invention solves another technological scheme that its technical problem adopts: comprise valve body, ball core, valve rod and handle, two ends of valve body is respectively equipped with suction tude and steam outlet pipe, handle drives ball core Spin Control combustion gas break-make by valve rod, security personnel's resetting-mechanism is set in steam outlet pipe, security personnel's resetting-mechanism comprises Sealing, slide bar and positioning seat, slide bar is movably arranged in the positioning seat, Sealing is fixed on slide bar one end and matches with the sealing surface that forms on the steam outlet pipe inwall, on the other end of slide bar magnet is set, magnet matches with magnetic patch on being arranged on the ball core.
Under the ball valve closed condition, the magnet on the slide bar is inhaled mutually with the magnetic patch on the ball core.
Slide bar overcoat security personnel spring, the two ends of security personnel's spring lean respectively on the back seat of positioning seat and slide bar.
The present invention is by above-mentioned specific design, can significantly reduce that the gas transmission leather hose comes off because of taking place when using combustion gas, aging cracking, the security incident of breaking etc. and to cause, in case the gas leakage accident takes place, valve will cut off source of the gas rapidly automatically, has the advantage of simple and compact for structure, safe and convenient to use, energy-saving and environmental protection, good reliability.
