Description
Technical field
The present invention relates to the connection set that a kind of gas piping connects and dismantle usefulness fast, be specifically related to a kind of rapid pipe joint.
Background technique
Rapid pipe joint is the device that is widely used in connecting between pipeline, has the performance of Quick fastening and quick-detachment, has inseparable relation for some industries relevant with gas.There are two class characteristics in rapid pipe joint in the market, and first kind characteristics are simple in structure, simple operations, and bales catch admittedly reaches bullet and takes off, but airtight effect is not ideal, and in the situation that especially pressure is higher, sealing effect is poorer, and moves inaccurate; The Equations of The Second Kind characteristics are complex structures, and assembling is slow, but tightness is good, and action is accurately taken off but bales catch reaches bullet admittedly.
Chinese patent CN201330906Y discloses a kind of rapid pipe joint, permanent joint and the moving joint that cooperates consists of by pegging graft, the endoporus of moving joint is gas-entered passageway, and permanent joint comprises body and Screw assembly at intrinsic sleeve pipe, and the endoporus of permanent joint is made of grafting passage and gas-entered passageway.Be provided with stop valve installation in the grafting passage, the valve seat of stop valve installation top is contained in sleeve pipe and stretches between the ring-shaped step on body one end and the inner body wall, the spool of one-way valve passes the endoporus of valve seat and endwisely slips and is assemblied in the permanent joint, be arranged with the seal ring that the endoporus with valve seat is sealed and matched on the spool head, when moving joint does not insert in the permanent joint, the stage clip of top dress makes the spool location between annular gear edge on the spool and the valve seat, rely on seal ring with the endoporus sealing of valve seat, in the time of in moving joint inserts permanent joint, the elastic force promotion spool that moving joint overcomes stage clip moves, the valve seat endoporus is opened, meanwhile, pore on the spool is communicated with gas-entered passageway, thereby makes outlet passageway and gas-entered passageway conducting.Outer wall at moving joint offers step-like annular groove, symmetry offers two radial direction extension conical through-holes on the outer wall of sleeve pipe, be respectively fitted with steel ball in two conical through-holes, flip sleeve is provided with sliding sleeve on the body, offer annular groove on the inwall of sliding sleeve, insert in the permanent joint process at moving joint, in the time of in steel ball is resisted against respectively the annular groove of sliding sleeve and in the annular groove of moving joint, moving joint and permanent joint locking; When release, promote sliding sleeve, make steel ball break away from annular groove until relative with the recessed shoulder of annular, meanwhile, moving joint is outwards mobile under the effect of spool spring, so that steel ball is resisted against on the annular recessed shoulder of sliding sleeve, finally realizes release.The stop valve installation of this rapid pipe joint can guarantee the sealing effect of whole rapid pipe joint, in the locking process, when moving joint promotion spool moves inward, under the spring action of top dress between ring-shaped step of sliding sleeve inwall and the body, the conical surface at the annular recessed shoulder place of sliding sleeve promotes to move in the steel ball, can realize auto lock, but in releasing process, promote sliding sleeve and need to overcome the elastic force of spring and steel ball to a reaction force that cell wall applies of annular groove, skidding occurs easily, causes the release difficulty.
