Description

A kind of fast assembling-disassembling double-ended pipe joint
Technical field
The utility model relates to a kind of pipe joint of fast demountable.
Background technique
The miniature valve joint of current use, thread type is generally adopted to connect, quick mounting is accomplished, as Chinese patent (application number: 2008100631056), but component can not be changed fast by multiple components such as snap ring, seal ring, snap ring, driving member, glands; Because the components such as seal ring belong to consumable material, use a period of time just to there will be the phenomenon such as aging and then have influence on the transport of medium in pipe, and when occurring that these reasons need repairing, then to need from pipeline head dismounting until damage joint is dismantled, have that workload is large, engineering time is grown, take time and effort, high in cost of production shortcoming.
Model utility content
For prior art Problems existing, on the basis of existing technology, the application provides a kind of pipe joint of fast demountable, and concrete technological scheme is as follows.
A kind of fast assembling-disassembling double-ended pipe joint that the application provides, comprise the seal ring (2) that tubing joinder (1) and tubing joinder (1) both sides are linked in sequence, snap ring (3), snap ring (4), driving member (5) and gland (6), described tubing joinder (1) is enclosed within the joint of two pipelines (8), described gland (6) and tubing joinder (1) are threaded connection, the inner side of described tubing joinder (1) is provided with annular boss (11), annular boss is provided with positioning ring (7), two end faces of described positioning ring (7) and the pipeline of both sides offset.
The width of positioning ring described in the application (7) is at least the width of one times of seal ring (2) wire diameter.
Preferably, the width of positioning ring described in the application (7) is the width of 1.5 times of seal ring (2) wire diameters.
Preferably, between seal ring (2) and tubing joinder (1), packing ring (9) is provided with.
In actual applications, also can realize quick-detachment by the distance of the seal ring wire diameter leaving at least one times in the joint of two pipelines (8) to install, when after seal ring (2) seal failure, unclamp gland (6), then snap ring (3), snap ring (4), driving member (5) and seal ring (2) lose external force, recover deformation, can move vertically on pipeline, the joint of two pipelines (8) is shifted out ,after inefficacy seal ring (2) pulls down replacing from the spacing of two pipeline end faces maintenances about 1 times of seal ring wire diameter, quick mounting completes, preferably, as described in the present application, positioning ring (7) is provided with in tubing joinder (1) inner side, then tubing joinder can on pipeline single-way moving vertically, the joint of two pipelines (8) is shifted out, after taking out positioning ring (7), then tubing joinder (1) can on pipeline vertically way moving (do not put positioning ring, realized by range line between two pipelines), after inefficacy seal ring (2) pulls down replacing from the spacing of two pipeline end faces maintenances about 1.5 times of seal ring wire diameters, put back to positioning ring (7), quick mounting completes, the replacing of seal element can be completed without the pipeline (8) on disassembling pipe and pipe fitting.
Beneficial effect: the pipe joint that the application provides achieves the dismounting easily and fast of double-ended pipe joint by the design of positioning ring inside tubing joinder, greatly provides cost savings, improves working efficiency.
Accompanying drawing explanation
The cross-sectional view of Fig. 1 fast assembling-disassembling double-ended pipe joint;
The structural representation of Fig. 2 fast assembling-disassembling double-ended pipe joint;
In figure: 1-tubing joinder, 2-seal ring, 3-snap ring, 4-snap ring, 5-driving member, 6-gland, 7-positioning ring, 8-pipeline, 9-packing ring, 11-annular boss.
Embodiment
Below in conjunction with accompanying drawing, explanation is further explained to the utility model.
As illustrated in fig. 1 and 2, for the double-ended pipe joint structural representation of the fast demountable that the application provides, it comprises seal ring 2, snap ring 3, snap ring 4, driving member 5 and gland 6 that tubing joinder 1 and tubing joinder 1 both sides are linked in sequence, described tubing joinder 1 is enclosed within the joint of two pipelines 8, described gland 6 is threaded connection with tubing joinder 1, the inner side of described tubing joinder 1 is provided with annular boss 11, and annular boss is provided with positioning ring 7.Also the fast assembling-disassembling of pipe joint can be realized in actual applications by the distance leaving at least one times of seal ring wire diameter two pipe couplings place.
Preferably, between seal ring 2 and tubing joinder 1, packing ring 9 is provided with.
When after seal ring 2 seal failure, unclamp gland 6, then snap ring 3, snap ring 4, the sealing components such as driving member 5 and seal ring 2 lose external force, recover deformation, can move vertically on pipeline, tubing joinder 1 also can on pipeline single-way moving vertically, the joint of two pipelines 8 is shifted out, after taking out positioning ring 7, then tubing joinder 1 can on pipeline vertically way moving (do not put positioning ring, realized by range line between two pipelines), after inefficacy seal ring 2 pulls down replacing from the spacing of two pipeline end faces maintenances about 1.5 times of seal ring wire diameters, put back to positioning ring 7, quick mounting completes, the replacing of seal element can be completed without the pipeline 8 on disassembling pipe and pipe fitting.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
