Abstract

The invention discloses a gas pipeline joint. The gas pipeline joint comprises a body, wherein a connection pipe communicated with the body is arranged on the body; the inner edges at two ends of the body have a bevel structure; a sealing ring and a pull-out resisting ring are arranged at a joint of the body and the excircle of the connection pipe; the sealing ring is a wedge-shaped rubber sealing ring; the wedge-shaped rubber sealing ring is arranged in a cavity formed by bevels at the end of the body, a clamp nut and the connection pipe; the clamp nut is screwed to ensure that the connection pipe slides relative to the body without causing leakage; the pull-out resisting ring is an open wedge-shaped nylon ring; and the clamp nut is screwed so as to prevent the connection pipe from being pulled out of the body to cause leakage. The gas pipeline joint has the advantages of simple structure, low cost, good sealing effect, high safety factor and long service life.

Description

The gas pipeline joint
Technical field
The present invention relates to a kind of pipe coupling, and be particularly related to a kind of gas pipeline joint of good sealing effect.
Background technique
As everyone knows, pipe coupling is a requisite link in the gas pipeline process of deployment, be used for two gas pipelines are connected and sealed, if because of the pipe coupling poor sealing, cause combustion gas to reveal, may cause bigger security incident, therefore high to its sealing and reliability requirement, traditional pipe coupling ubiquity complex structure, the shortcoming that sealing effect is bad and safety reliability is not high.
Summary of the invention
The object of the present invention is to provide a kind of gas pipeline joint, it has simple in structure, good sealing effect and safe and reliable characteristics.
The objective of the invention is to be achieved through the following technical solutions:
A kind of gas pipeline joint, it comprises body, the connecting tube that is connected with body is installed on the described body, wherein, the connecting part of described body and connecting tube cylindrical is provided with seal ring, described seal ring is pressed between connecting tube and the body by tightening nut, and the connecting part of described body and connecting tube cylindrical also is provided with the resistance to plucking circle.
The two ends inner edge of described body is a ramp structure, and described seal ring is the wedge-shaped rubber seal ring, and described wedge-shaped rubber seal ring places in the cavity volume that is formed by body end inclined-plane, nut and connecting tube.
The wedge shape nylon ring that described resistance to plucking circle is an opening closely is sheathed on the cylindrical of connecting tube.
Beneficial effect of the present invention is, described gas pipeline joint is not only simple in structure, and cost is lower; And good sealing effect, safety coefficient height, long service life.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of gas pipeline joint of the present invention.
Among the figure:
1, body; 2, tightening nut; 3, resistance to plucking circle; 4, wedge-type seal circle; 5, connecting tube.
Embodiment
Please refer to shown in Figure 1, Fig. 1 is the structural representation of gas pipeline joint of the present invention, in present embodiment, a kind of gas pipeline joint, it comprises body 1, the connecting tube 5 that is connected with body 1 is installed on the described body 1, and the two ends inner edge of described body 1 is a ramp structure, described body 1 is provided with wedge-type seal circle 4 with the connecting part of connecting tube 5 cylindricals, described wedge-type seal circle 4 is made for rubber material, and wedge-type seal circle 4 places by body 1 end chamfer, in the cavity volume that tightening nut 2 and connecting tube 5 form, make the inclined-plane of tightening nut 2 compress wedge shape seal ring 4 by tightening solid nut 2, thereby the cylindrical that makes wedge-type seal circle 4 produce resiliently deformable extrusion body 1 inclined-plane and tightening nut 2 inclined-planes and connecting tube 5 reaches sealing purpose, and assurance connecting tube 5 slides with respect to body 1 and do not leak; And described body 1 also is provided with resistance to plucking circle 3 with the connecting part of connecting tube 5 cylindricals, described resistance to plucking circle 3 is the wedge shape nylon ring of opening, closely be sheathed on the cylindrical of connecting tube 5, the screwing force by tightening nut 2 prevents that connecting tube 5 from pulling out to form and leaks from body 1.
The described wedge-type seal circle 4 that utilizes has guaranteed that connecting tube 5 slides with respect to body 1 and do not leak, and relies on the screwing force of tightening nut 2 to prevent that connecting tube 5 from pulling out to form simultaneously from body 1 and leaks, and not only simple in structure, cost is lower; And good sealing effect, safety coefficient height, long service life.
