Abstract
The utility model relates to a pipe joint, which comprises a connecter with an external thread and a screw cap. At least one groove, which comprises a sealing ring, is grooved along the circumferential direction on the inner wall of the connecter. The sealing ring achieves a great sealing effect when a pipe is inserted in the pipe joint.
Description
The utility model relates to a kind of pipe joint.
At present, it is activity clamping one extrusion metal circle between threaded connector and nut that a kind of pipe joint is arranged, the periphery of extrusion metal circle is wedge, the opening end of link and nut also is an oblique shape opening corresponding to extrusion metal circle wedge end, after pipe fitting inserted joint, nut and link are screwed, utilize nut and link, reach sealing pipe fitting joint to the extrusion-deformation of wedge eyelet.The structure that this elder generation seals by eyelet extrusion-deformation, unsatisfactory in actual practicality, when being threaded closely, cause leakage easily; In addition, the extrusion-deformation of eyelet is very unreliable, and after the extruding, eyelet might not all encase sealing with pipe fitting, and sealability is not good; Simultaneously, after joint is vibrated, also cause leakage easily.
The purpose of this utility model is to provide a kind of pipe joint of good seal performance.
For achieving the above object, the utility model by the following technical solutions
A kind of pipe joint comprises and is with externally threaded link and nut, along the circumferential direction opens at least one groove at the link inwall, the embedded seal ring of receiving of groove.Like this, pipe fitting can utilize seal ring to reach good sealing effect after inserting joint.
Above-mentioned pipe joint, activity clamping one extrusion metal circle between link and nut, the periphery of described extrusion metal circle is wedge, and the opening end of link and nut also is an oblique shape opening corresponding to extrusion metal circle wedge end.Eyelet can be fixing better with pipe fitting.
Above-mentioned pipe joint, establish one in link to be used to withstand the shoulder of pipe fitting termination prominent along the rear end of pipe fitting direction of insertion groove.The shoulder lug structure can be located pipe fitting exactly.
The utility model will be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the utility model schematic representation.
With reference to accompanying drawing, number in the figure and parts are threaded connector 1, seal ring 2, outside thread 3, internal thread 4, nut 5, pipe fitting 6, wedge extrusion metal circle 7.
Embodiment 1:
With reference to accompanying drawing, the described pipe joint of present embodiment, comprise and be with externally threaded link and nut, activity clamping one extrusion metal circle between link and nut, the periphery of extrusion metal circle is wedge, and the opening end of described link and nut also is an oblique shape opening corresponding to extrusion metal circle wedge end; Along the circumferential direction open a groove at the link inwall, the embedded seal ring of receiving of groove; Establish simultaneously one in link to be used to withstand the shoulder of pipe fitting termination prominent along the rear end of pipe fitting direction of insertion groove.
Like this, after pipe fitting inserted connecting head, seal ring just directly played seal action, and the screw-thread fit of utilizing nut and link is with the extrusion-deformation of wedge seal ring, and this extrusion-deformation both can be fixed pipe fitting, can play certain sealing effect again.
Certainly, only utilize embedded seal ring, do not use eyelet also can reach sealing effect.
In addition, do not take on lug structure and also pipe fitting can be fixed in the connecting head, just had shoulder prominent, it is more accurate to locate.
The utility model goes for the various occasions that pipe fitting connects, for example tee union etc.; And the utility model is also applicable to the occasion of non-threaded connection.
Claims (3)
1, a kind of pipe joint comprises and is with externally threaded link and nut, it is characterized in that along the circumferential direction opening at least one groove at the link inwall the embedded seal ring of receiving of groove.
2, the described pipe joint of claim 1 is characterized in that activity clamping one extrusion metal circle between link and nut, and the periphery of described extrusion metal circle is wedge, and the opening end of link and nut also is an oblique shape opening corresponding to extrusion metal circle wedge end.
3, the described pipe joint of claim 1, it is characterized in that in link establishing along the rear end of pipe fitting direction of insertion groove one, to be used to withstand the shoulder of pipe fitting termination prominent.
