Description
Technical field
The utility model relates to cylinder valve technical field, especially relates to being arranged on cylinder valve and being used for the self-closing formula joint of pegging graft.
Background technique
At present, traditional cylinder valve air outlet is that open type is threaded, be that gas cylinder is threaded connection reduction valve and is connected with gas tool, gas in bottle is finished, and while changing gas, reduction valve be screwed out, again reduction valve precession is had to the gas cylinder of gas, Renewal process is loaded down with trivial details, and complicated operation is installed the bad Leakage Gas that very easily causes.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of self-closing formula joint of gas cylinder Leakage Gas and cylinder valve that self-closing formula joint is installed of preventing.
For solving the problems of the technologies described above adopted technological scheme: a kind of self-closing formula joint of cylinder valve, comprise a loose joint daughter, loose joint daughter is threaded with the air outlet of cylinder valve, between air outlet and loose joint daughter, be provided with for sealing the O RunddichtringO of both connecting sewings, it is characterized in that: in the chamber of described loose joint daughter next-door neighbour air outlet, the post rod type nonreturn valve core leaking in order to barrier gas is installed, an if valve seat, valve seat is fitted in air outlet by loose joint daughter, the push rod flip sleeve of nonreturn valve core is through on valve seat, on valve seat, offer some vents, between valve seat and nonreturn valve core, be provided with and keep nonreturn valve core to close the Compress Spring of trend, outer section of conical valve pad that is set with nonreturn valve core of push rod, the corresponding valve pad of loose joint daughter inner chamber place is formed with the step hole of being closed by valve pad, the head of push rod forms and extends the top that is subject to that can be pushed up by loose joint parent outside step hole, in the chamber of loose joint daughter near outer end, be provided with and can form with loose joint parent the seal ring of sealing, loose joint daughter offers the annular groove with the clamping of loose joint parent near the outer wall of outer end.
For solving the problems of the technologies described above adopted another technological scheme: a kind of cylinder valve that self-closing formula joint is installed, include cylinder valve, the sidepiece of cylinder valve offers air outlet, it is characterized in that: establish a loose joint daughter, loose joint daughter is threaded with the air outlet of cylinder valve, between air outlet and loose joint daughter, be provided with for sealing the O RunddichtringO of both connecting sewings, in the chamber of loose joint daughter next-door neighbour air outlet, the post rod type nonreturn valve core leaking in order to barrier gas is installed, an if valve seat, valve seat is fitted in air outlet by loose joint daughter, the push rod flip sleeve of nonreturn valve core is through on valve seat, on valve seat, offer some vents, between valve seat and nonreturn valve core, be provided with and keep nonreturn valve core to close the Compress Spring of trend, outer section of conical valve pad that is set with nonreturn valve core of push rod, the corresponding valve pad of loose joint daughter inner chamber place is formed with the step hole of being closed by valve pad, the head of push rod forms and extends the top that is subject to that can be pushed up by loose joint parent outside step hole, in the chamber of loose joint daughter near outer end, be provided with and can form with loose joint parent the seal ring of sealing, loose joint daughter offers the annular groove with the clamping of loose joint parent near the outer wall of outer end.
The beneficial effect that adopts the utility model to bring: adopt cylinder valve of the present utility model to realize by loose joint mode the reduction valve matching with it and connect, make the replacing simple and fast of steel cylinder, safe and reliable.The sub-jiont treatment of loose joint is at cylinder valve, and female joint is arranged on reduction valve, and sub-joint is plugged in female joint, utilizes lock tube and ball in female joint to coordinate with the locking of the annular groove of sub-joint, the connection locking of bundle joint and female joint.During grafting, the middle part push rod of female joint withstands the sliding mandril of sub-joint, and nonreturn valve core, toward interior slip, leaves step hole, and cylinder valve and reduction valve are communicated with.And while pulling out female joint, nonreturn valve core is promoted to reset by spring, be pressed on step hole, the gas channel of cylinder valve is closed, prevent Leakage Gas in steel cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is provided with the cylinder valve of self-closing formula joint.
Embodiment
