Abstract

The utility model discloses a locking type connector for a pipeline, which comprises a pipe joint body, and both ends of the pipe joint body are axial holes. The utility model is characterized in that longitudinal pipe wall of the pipe joint body is V- shaped; an asbestos ring, an iron ring and an aluminum ring are arranged on the bevel of a pipe wall in turn; the circumference of the protruded axial hole are provided with more than four convex dots. The asbestos ring, the iron ring and the aluminum ring are arranged on the bevel of the pipe wall to realize the sealing effect, and thus the utility model has the advantages that the heat-resisting performance is strong, the pollution is not generated, no looseness can be ideally realized when the pipeline is connected with a pipe element, the tight locking is realized, and the long service life is realized.

Description

The closing type pipeline connecting parts

The utility model relates to a kind of closing type pipeline connecting parts, is applicable to all size, and the pipeline of shape and various materials is connected.

Existing expansion self-locking formula pipeline connecting parts, it has a union body, there is a conical butt axial bore that outwards closes up its end, the built-in elastic seal ring in hole, expansion loop and clamp ring, its shortcoming is: when pipe joint matches with pipeline, between easily slide, moreover the material of expansion loop and clamp ring be adopt plumbous, relatively poor and pollution is arranged because of the rigidity of lead, so distortion will occur and become flexible when cooperating with iron phase.

Good rigidly when the utility model proposes a kind of pipe joint and is connected with pipeline at above-mentioned shortcoming, be difficult for loosening, pollution-free, prolong the pipeline closing type pipeline connecting parts in working life.

Task of the present utility model be finish like this, it comprises union body, its two ends are axial bores, it is characterized in that: the vertical tube wall of union body is " eight " font, and asbestos ring is housed on the inclined-plane in the tube wall successively, iron ring and aluminium circle have the dome point more than four around the outstanding axial bore.

The utlity model has following effect: thus since tube wall in the inclined-plane on install be asbestos ring, iron ring and aluminium circle reach the sealing resistance to heat strong, pollution-free, loosening when having reached pipeline more satisfactoryly and being connected with pipe fitting, block tight, effects such as long service life.

Fig. 1 is a structure scheme of installation of the present utility model;

Fig. 2 is a direct-type structural representation of the present utility model;

Fig. 3 is a bending head type structural representation of the present utility model;

Fig. 4 is a Three way type structural representation of the present utility model

Describe embodiment in detail in conjunction with above accompanying drawing, the vertical tube wall of union body after the mould founding is come out is " eight " font 3, dome point 7 more than four is arranged around the outstanding axial bore 2, pipe joint is enclosed within on the external diameter of pipe 1, successively asbestos ring 4 and fastening ring 5, iron ring 6 are installed on the inclined-plane in the union body tube wall, compress with special tool and to get final product, owing on around the axial bore 2, dome point 7 is arranged, make the above three circle on the inclined-plane in the tube wall, be difficult for coming off from the axial bore 2 of pipe joint.In using installation process, with pipe 1 supporting direct-type arranged, bending head type, Three way type, this closing type pipeline connecting parts have formed pipeline and have connected seriation, normalization.

Claims

1, the closing type pipeline connecting parts, it comprises union body, its two ends are axial bores, it is characterized in that: the vertical tube wall of union body is " eight " font, and device has asbestos ring, iron ring and aluminium circle successively on the inclined-plane in the tube wall, and the dome point more than four is arranged around the outstanding axial bore.
