Place, so that self-locking function is realized, for being difficult or can not dismantle this valve, thus effectively in the case where no specific purpose tool
Ground eliminates safe hidden trouble problem.
Optionally, when removing valve (at this point, the liquefied gas in liquefied gas bottle 601 has been used up certainly), can first by
Plug 503 is disassembled from plug connector 505, so that the inside of liquefied gas bottle 601 passes sequentially through pedestal 201, gas cylinder connector
504 and plug connector 505 be in communication with the outside, at this point, disassembly personnel can use an iron plate, then by one end of iron plate from
Plug connector 505 extend into self-locking device 101 from 301 position of lock core body, recycle iron hammer hammering iron plate the other end, will
Reset spring 303 and/or spring pedestal 305 are to destroying, so that Bolt with latching action 304 falls off, to lose self-locking function, finally
Valve can be disassembled from liquefied gas bottle 601.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.
