Description
Technical field
The present invention relates to a kind of for can the fast insert-pull joint of fast insert-pull gas pipeline.
Background technique
Chinese patent literature CN103148300A discloses a kind of fast insert-pull joint, the outer valve joint comprising interior valve joint and dock with it, described interior valve joint and outer valve joint are hollow cylinder, the spring spool of fluid stopping is provided with in the middle of interior valve joint, outer valve joint axle center is provided with the spring valve plug of same fluid stopping, spring spool and spring valve plug push up pressure mutually, and fast insert-pull joint can be made through-flow; Interior valve joint is connected with the locking device of outer valve joint by their joints.Although this fast insert-pull joint can realize the fast insert-pull of joint, but, the conducting of this fast insert-pull joint runner is pressure difference by interior valve joint and outer valve joint spring separately and conducting, so just exist when the elastic force of respective spring changes, although will both grafting, its inner passage have the problem of conducting; In addition, the fast insert-pull joint of this structure can not realize before interior valve joint and outer valve joint are extracted, and the pressure realized in external valve joint carries out the function of pressure release in advance, therefore, is not too suitable for the conveying of gas.
Chinese patent literature CN201934836U discloses a kind of quick inserting trachea and carries the gas-tpe fitting of degassing function.It comprises socket, umbellate form seal ring, spigot, O RunddichtringO, O RunddichtringO, tracheae bayonet socket and O RunddichtringO composition.First umbellate form seal ring is loaded in the hole on socket top, then O RunddichtringO is enclosed within the seal groove of spigot outside, O RunddichtringO loads the Kong Zhongzai on spigot top and tracheae buckle is snapped in and to be pressed into together in the hole on socket top and socket upper hole is riveted, interior socket, by the sealing of O type circle, is finally inserted in O RunddichtringO in the seal groove of socket bottom.It is moving around by umbellate form seal ring that this tracheae connects, and reaches air inlet or exhaust object, and this just needs gas-tpe fitting two ends to have pressure just can work, and it is not suitable for the pressurize of gas-tpe fitting one end, and another needs to use when pressure release.
Summary of the invention
In order to overcome the problems referred to above, the present invention provides a kind of formation of gas channel not need to realize by the pressure difference of two springs to society, and can be suitable for the pressurize of gas-tpe fitting one end, and another needs the fast insert-pull joint used when pressure release.
Technological scheme of the present invention is: provide a kind of fast insert-pull joint, comprise shell, one end in described shell is fixed with spigot, and the other end in described shell is fixed with inlet connecting, is provided with the button hole for placing button and locating piece at the middle part of described shell; In described shell, from described spigot, be provided with slip joint successively, be enclosed within the return spring on the afterbody of described slip joint, and locating piece, button, pressure release assembly, dicyclo non-return Sealing and arrow-shaped check valve; The afterbody outer wall of described slip joint is provided with the first positioning ring; Described locating piece comprises the first through hole, and the lower inwall of described first through hole is provided with the first half card convex rings, is provided with top retaining spring on said bottom between the outer wall of the bottom of described first through hole and the inwall of described shell; Described button comprises the second through hole, the rear portion of described arrow-shaped check valve, dicyclo non-return Sealing and pressure release assembly is arranged in the insertion part of inlet connecting, and is provided with the step for preventing arrow-shaped check valve from exiting in inlet connecting at the root of described insertion part; When described slip joint inwardly promotes by external force, described slip joint afterbody is successively by moving after the first through hole and the second through hole, and described return spring is compressed, and described the first half card convex rings are under the effect of described retaining spring, be hooked in described first positioning ring, described slip joint is located; Now, the tail end of described slip joint acts on the front end of arrow-shaped check valve, moves after making arrow-shaped check valve, and the openwork hole of arrow-shaped check valve makes the runner conducting in shell; Pressing button, described button acts on locating piece, described the first half card convex rings and described first positioning ring are broken off relations, described slip joint return under the effect of described return spring, simultaneously, under the effect of the gas pressure in described inlet connecting, the outer tapering of arrow-shaped check valve and the interior tapering of dicyclo Sealing closely cooperate, and cut off runner.
As improvement of the present invention, on the afterbody outer wall of described slip joint, rear portion by described first positioning ring is also provided with the second positioning ring, the upper inwall of described second through hole is also provided with the second half card convex rings, described the second half card convex rings and described the first half card convex rings spatially misplace, when pressing the button, described the second half card convex rings are stuck in described second positioning ring, only allow described slip joint part return, now, the gas in shell and in steam outlet pipe is by being positioned at the pressure release of releasing on outer casing inner wall.
As improvement of the present invention, on the inwall of described spigot, the outer end of inner joint is provided with the groove for dodging to card bead, and and then groove is provided with the internal projecting ring for withstanding described card bead; The card ball that several are placed with card ball is evenly provided with in the front portion of described slip joint; When described slip joint moves inward, described card bead is ejected by described internal projecting ring, blocks male connector and does not allow it come off; When described slip joint outwards moves reset, male connector, just to described groove, discharges by described card bead.
As improvement of the present invention, the external sealing be provided with in described slip joint for sealing male connector is close.
As improvement of the present invention, between described button and shell, be provided with push piece joint.
As improvement of the present invention, described pressure release assembly comprises front pressure release part and rear pressure release part, between described front pressure release part and rear pressure release part, be provided with pressure relief sealing ring, on the rear end of the second seal ring set of described dicyclo non-return Sealing pressure release part in the rear.
As improvement of the present invention, the front portion of described rear pressure release part is enclosed within the afterbody of described front pressure release part, and described pressure relief sealing ring is established between the afterbody of the front portion of pressure release part in the rear and described front pressure release part.
As improvement of the present invention, described arrow-shaped check valve comprises arrow tail, and described arrow tail is made up of the empennage of more than three, and described empennage is connected with outer tapering, described outer tapering is connected with the hollow out frame being provided with more than one openwork hole, and described hollow out frame is connected with described front end.
As improvement of the present invention, be provided with some outer gap at described front end.
As improvement of the present invention, described locating piece copper is done.
The present invention is owing to have employed when runner conducting, directly safety check is backed down with slider, when cutting off runner, by managing interior gas pressure, tapering in safety check and dicyclo Sealing is closely cooperated, and cut off the structure of runner, so the formation that the present invention has gas channel does not need to realize by the pressure difference of two springs, and can be suitable for the pressurize of gas-tpe fitting one end, another needs the advantage used when pressure release.
