Abstract

The utility model discloses an anti-leakage pipe, which is mainly composed of a pipe body. The utility model is characterized in that the pipe port end of the utility model forms a bulge section. The utility model is reasonable in structure; when the utility model is used, the pipe port forming the bulge section is closely connected with a bearing groove under the action of external pressure and the fastening action of pressing nuts; besides, the pipe port which is in the shape of the expansion joint can be regulated by deformation under the action of the pressure, and therefore, the sealing effect is ensured. The installation method of the utility model is simple and easy in implementation, the sealing performance is good, and the utility model overcomes the defect that the traditional filament port connection method easily generates leakage after great pressure or heat expansion and cold contraction.

Description

High temperature resistant, high pressure, press solidly the anti-leak pipe

Technical field:

The utility model relates to a kind of pipeline parts, particularly relates to the anti-leak pipe relevant with motive sealing, static seal and mechanical seal in a kind of pipeline connection.

Background technique:

It is an integrated technology that pipeline connects, and in modern industry and various fields in science and technology, has purposes and effect widely.At present, equipment leakage phenomenon in the fields such as whole world machinery, chemical industry is quite universal, it is long-term chronic disease, not only cause the waste of the energy and material, and jeopardize personal safety, and influencing quality of product, its main cause is that sealing configuration is unreasonable, seal element and material selection are improper, cause poor sealing performance.

Summary of the invention:

Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, at good high temperature resistant, the high pressure of high temperature, high pressure lower seal performance, press solidly the anti-leak pipe.The technological scheme that its technical problem that solves the utility model adopts is, a kind of anti-leak pipe mainly is made up of body, and its characteristics are: nose end is the distension nodular.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, be skillfully constructed, during use, externally under the fastening acting in conjunction of pressure and gland nut, the distension nodular mouth of pipe closely links to each other with holding groove, in addition, the mouth of pipe of distension nodular can be regulated by deformation under pressure, so guaranteed sealing effect.This installation method is simple and easy to do, and favorable sealing property has overcome traditional silk mouthful Placement at big pressure or after expanding with heat and contract with cold, the defective of yielding leakage, tool promotional value.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Structural representation when Fig. 2 joins for the utility model and a valve.

Embodiment:

Referring to Fig. 1, a kind of high temperature resistant, high pressure, press solidly the anti-leak pipe, mainly to form by body 1, nose end 2 is the distension nodular.Referring to Fig. 2, the jointing of valve 5 offers a holding groove 3, and the cross section of this groove is trapezoidal.After embedding in the holding groove 3, the mouth of pipe 2 of anti-leak pipe make both fastening by a gland nut 4.Be connected with valve when using, externally under the fastening acting in conjunction of pressure and gland nut 4, the distension nodular mouth of pipe 2 closely links to each other with holding groove 3, owing to the mouth of pipe of distension nodular can be regulated by deformation under pressure, so guaranteed sealing effect.

Claims

1, a kind of anti-leak pipe mainly is made up of body, it is characterized in that: nose end is the distension nodular.
