Abstract
The utility model relates to a leak-proof quick-speed connector of a pipeline, which comprises pipelines which are face to face inserted on both ends of a connector body, a sealing ring is arranged between the pipelines and the connector body, a clamp nut which is connected with screws thread of the connector body is arranged between a pipe on the rear end of the sealing ring and the connector body, the periphery of the clamp nut is provided with a fastener, and the sealing face between the sealing ring and the inner wall of the connector body is a pyramidal face. The utility model overcomes the shortcomings of the prior art that a normal connector of a pipeline has worse sealing effect and more tedious assemblage, with the design, the utility model greatly improves the sealing effect of the connector of the pipeline, which has the advantages of compact structure, rapid assemblage, convenience and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of pipeline leakproof rapid pipe joint.
Background technique
The joint of conventional pipelines, its sealing effect is relatively poor, and when using in various pipeline networks, its joint part leakage phenomenon occurs through regular meeting.
Summary of the invention
In order to overcome the problem that common pipe joint sealing effect is relatively poor in the prior art, assembling is more loaded down with trivial details, the utility model provides a kind of pipeline leakproof rapid pipe joint, compact structure, good sealing effect, the good reliability of this pipeline leakproof rapid pipe joint.
The technological scheme that its technical problem that solves the utility model adopts is: comprise being inserted in the pipeline at fittings body two ends, be provided with seal ring between pipeline and the fittings body, be provided with the gland nut that is threaded with fittings body between the pipe of seal ring rear end and the fittings body.
The periphery of gland nut is provided with fastening piece.
Fastening piece is the nut that is threaded with gland nut or tightens the fastening screw trip bolt that is pressed in circle or the gland nut on the pipeline.
Sealing surface between seal ring and the fittings body inwall is the conical surface.
The utility model has improved the sealing effect of pipe coupling greatly by above-mentioned specific design, has compact structure, assembles advantage quick and easy, good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is the utility model embodiment two a structural representation;
Fig. 3 is the utility model embodiment three a structural representation.
Embodiment
As shown in the figure, the utility model comprises being inserted in the pipeline 2 at fittings body 1 two ends, be provided with seal ring 3 between pipeline 2 and the fittings body 1, sealing surface between seal ring 3 and fittings body 1 inwall is the conical surface, be provided with the gland nut 4 that is threaded with fittings body 1 between the pipeline 2 of seal ring 3 rear ends and the fittings body 1, behind the gland nut 4 precession fittings bodies 1, roof pressure seal ring 3 makes the sealing surface between seal ring 3 and fittings body 1 inwall fit tightly the maintenance sealing.The periphery of gland nut 4 is provided with fastening piece, and fastening piece can be that as shown in Figure 1 nut 5 that is threaded with gland nut 4 or tightening as shown in Figure 2 is pressed on fastening screw trip bolt 7 on the pipeline 2 in circle 6 or the gland nut 4 as shown in Figure 3.The reliability of connection between pipeline 2 and the fittings body 1 can be further strengthened in the design of fastening piece.
