Description
Technical field
The present invention relates to field of mechanical technique, more specifically, particularly a kind of locking rapid pipe joint.
Background technique
In daily life, the transmission of fluid all needs to be undertaken by pipe-line system.And in whole pipe-line system, owing to being subject to the restriction of length, be all be made up of multistage pipeline, the connection between multistage pipeline needs to be undertaken by pipe fittings such as joints.In order to reach Pipe installing object easily, people devise various rapid pipe joint.The structure of existing rapid pipe joint mostly by joint body, and is arranged on intrinsic distribution in the form of a ring and is tilted to interior pawl sheet and is positioned at pawl sheet the cover that unloads that joint body oral area side arranges and form.When installing water pipe, water pipe inserts joint, and pipe outer wall is pushed pawl sheet and opened, and after putting in place, pawl sheet blocks pipe outer wall, makes it to extract, reaches the object of quick links.To extract water pipe, then the cover that unloads utilizing caliber to be greater than water pipe extrudes pawl sheet, makes it to lose clamping force, thus is extracted by water pipe.But this rapid pipe joint also also exists defect.Pawl sheet only can block the tubing made by the lower material of hardness, and tubing as high in the hardness such as stainless steel, copper pipe then can not reliably connect, and pawl sheet easily scratches water tube surfaces, affects sealing.
In order to improve the connectivity robustness of tubing and joint, conventional method is by the technique at fitting end peripheral axial lock fixed position processing ring groove, and when tubing inserts in joint, profile of tooth collar incision groove improves the soundness of connection.Its bellmouth by lining, collar, back cushion, O type circle, unload cover etc. and form, complex structure, manufacture process requirement is high.Although applied widely, connection reliability is poor.
Summary of the invention
The present invention is intended at least solve one of Problems existing in background technique.
An object of the present invention is to provide a kind of locking rapid pipe joint, utilizes the connection realized between described rapid pipe joint and adapter that described rapid pipe joint is quick and stable.
For achieving the above object, the invention provides a kind of locking rapid pipe joint, it comprises and is arranged on the first seal element in described rapid pipe joint and elastic device, also comprises the second seal element be arranged between described first seal element and described elastic device.
Being connected with elastic device by installing the second seal element additional, improving the reliability of the connection between described rapid pipe joint and adapter, meanwhile, the first seal element not affected by other parts, provides the sealing effect of described rapid pipe joint greatly.
Further, described first seal element and described second seal element can be seal ring.
Further, described elastic device can be butterfly spring, also can be helical spring, can also be annular spring.

Further, it also comprises and being arranged in described rapid pipe joint and the lining be connected with described second seal element, is provided with maintainance set, described maintainance set is provided with locking element in described lining; Described elastic device to be arranged in described lining and to be connected with described maintainance set.
Adopt described lining to strengthen reliability that tubing is connected with described rapid pipe joint and intensity.
Described maintainance set and described second seal element is connected by adopting elastic device, described rapid pipe joint is connected with tubing and water flowing, described elastic device available buffer is adopted to change the described maintainance set shift in position caused because of hydraulic pressure, thus the motion slowed down between tubing and described rapid pipe joint, improve stability and the described rapid pipe joint carrying hydraulic pressure ability of connection, also improve the sealing effect of described rapid pipe joint simultaneously.
Further, the cross section of described locking element is circular.
Described locking element can be spherical balls, also can be American football shape steel ball, also can be the rigid ball of other materials.
When the cross section of described locking element is circular, the inwall of described locking element, tubing and described rapid pipe joint is more easily locked.
Further, described lining reduces gradually toward its internal diameter of one end of the described rapid pipe joint mouth of pipe.
When tubing is to described rapid pipe joint access, described tubing contacts with described locking element, locking element is moved to described lining inwall, when tubing will exit described rapid pipe joint, tubing and described locking element move to the described rapid pipe joint mouth of pipe, but described lining reduces gradually toward its internal diameter of one end of the described rapid pipe joint mouth of pipe, when described locking element and tubing point of contact to the distance between locking element and described lining contact internal walls point and interface external diameter sum are greater than described bushing inner diameter, tubing and described lining are locked, when tubing exits described rapid pipe joint further, lock wire can produce naturally, described rapid pipe joint and tubing more and more tighter.
Further, described maintainance set reduces gradually toward its external diameter of one end of the described rapid pipe joint mouth of pipe.
Its internal diameter of described maintainance set one end reduces gradually, facilitates the relative movement of described maintainance set and described lining.
Further, described rapid pipe joint outer wall is provided with the first convex shoulder and the second convex shoulder, and described rapid pipe joint inwall is provided with the first flanged structure be connected with described first seal element and the second flanged structure be connected with described second seal element.
The id tolerance described first seal element and described second seal element being positioned to described rapid pipe joint inwall place controls, described first seal element and described second seal element is made to form certain compression ratio, when tubing inserts described rapid pipe joint, under the protection of joint, tubing is not yielding, and outside and the first seal element and the second seal element close contact, form wider potted line, this provides Reliable guarantee for sealing; Described second flanged structure blocks described second seal element, and described second seal element blocks described elastic device, and described elastic device is propping up described maintainance set, thus the locking making described rapid pipe joint more stable adapter.
Further, it also comprises unloads cover, described in unload cover one end be arranged between described lining and described maintainance set, the other end extends the mouth of pipe of described rapid pipe joint.
When tubing being exited described rapid pipe joint, pushed away by the described cover that unloads to described bush inside, promote described maintainance set mobile to described rapid pipe joint inside, described locking element is no longer subject to the extruding of tubing and described lining inwall, at this moment can exit tubing.
Further, described rapid pipe joint inwall is also provided with the 3rd flanged structure.
Described 3rd flanged structure enters described rapid pipe joint for stoping tubing to continue.
Beneficial effect of the present invention is, a kind of locking rapid pipe joint is provided, this rapid pipe joint is connected with elastic device by installing the second seal element additional, improve the reliability of the connection between described rapid pipe joint and adapter, simultaneously, first seal element is not affected by other parts, provides the sealing effect of described rapid pipe joint greatly.
