Abstract

The utility model provides a ring crush ring clip type thin wall metal pipeline connector, which comprises a pipe connector body (1), a packing ring (6) and a pipe body (4), wherein an inner shoulder hole (2) and an inner shoulder hole (3) are arranged in the inner wall of at least one end of the pipe connector body (1) from inside to outside in turn, the packing ring (6) and a steel ring (5) are arranged in the inner shoulder hole (3) from inside to outside in turn, the end portion of the pipe body (4) is traversed through the steel ring (5) and the packing ring (6) in turn and is inserted in the inner shoulder hole (2), and two ends of the inner shoulder hole (3) are pressed in a ring mode to form the ring crush ring clip type thin wall metal pipeline connector. The connector has simple and practical structure and design, good sealing performance, solid connection, long service life, easy processing and manufacture and low cost.

Description

A kind of ring pressure ring cassette thin-wall metal pipe connector

Technical field

The utility model relates to a kind of metallic conduit connecting body, specifically, relates to a kind of ring pressure ring cassette thin-wall metal pipe connector.

Background technique

Existing pipeline Placement, generally be by screw thread or be welded to connect, this Placement processing intensity is big, installment work efficient is lower, the technology more complicated, and pipe fitting need reprocess just and can meet connection request, and production process is many, lose time, these all are difficult to satisfy the needs that society builds fast.

China Patent No. is 03234617.4, denomination of invention discloses a kind of link that connects tubing for the utility model patent of " ring pressure type pipeline connecting parts ", this link structural design is simple, easy to connect, it is with after being connected body and encircling pressure, make this link form hollow slot on the body, and reach the purpose that the two is connected firmly with this with being connected; But in actual applications, if the ring compression degree is not enough, then the hollow slot cup depth is limited, and this link just can not get ensureing that if the ring compression degree is bigger, then destructible tubing also influences the connecting body beautiful shape simultaneously with the connectivity robustness that is connected body; And this link linkage structure is more single, and the seal ring sealing configuration adopts traditional line seal structure, under the bigger situation of pressure, and the deficiency that its sealability and anti-pressure ability just manifest.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good seal performance, compressive strength are big, the ring pressure ring cassette thin-wall metal pipe connector of long service life thereby provide.

Goal of the invention of the present utility model is to realize by following technological scheme:

A kind of ring pressure ring cassette thin-wall metal pipe connector, comprise pipe fitting joint body 1, seal ring 6 and body 4, the inwall of described pipe fitting joint body 1 at least one end is by shoulder hole 2 and interior shoulder hole 3 in lining and outer being disposed with, reach outer be disposed with seal ring 6 and steel loop 5 by the lining in the shoulder hole 3 in described, the end of described body 4 passes described steel loop 5 successively and seal ring 6 is plugged in the described interior shoulder hole 2, and ring presses described interior shoulder hole 3 two ends to encircle pressure ring cassette thin-wall metal pipe connector to form.

The inner diameter of shoulder hole 2 is less than the inner diameter of shoulder hole 3 in described in described.

Described body 4 is Spielpassung with described interior shoulder hole 2.

Described steel loop 5 is stainless steel cylinder steel loops.

The utility model has substantive distinguishing features and progressive with respect to prior art, and specifically, this connecting body structural design is simple and practical, and good seal performance is connected firmly, long service life, and be easy to manufacturing, cost is low.

Description of drawings

Fig. 2 is a structural representation of the present utility model.

Embodiment

For advantage of the present utility model and technical characteristics further are described, provide embodiment of the present utility model below in conjunction with accompanying drawing:

As depicted in figs. 1 and 2, a kind of ring pressure ring cassette thin-wall metal pipe connector, comprise pipe fitting joint body 1, seal ring 6 and body 4, the inwall of described pipe fitting joint body 1 one ends is by shoulder hole 2 and interior shoulder hole 3 in lining and outer being disposed with, reach outer be disposed with seal ring 6 and steel loop 5 by the lining in the shoulder hole 3 in described, the end of described body 4 passes described steel loop 5 successively and seal ring 6 is plugged in the described interior shoulder hole 2, and ring presses described interior shoulder hole 3 two ends to encircle pressure ring cassette thin-wall metal pipe connector to form.

Described body 4 is Spielpassung with described interior shoulder hole 2;

The inner diameter of shoulder hole 2 is less than the inner diameter of shoulder hole 3 in described, so that in the shoulder hole 3 seal ring 6 and steel loop 5 are set in described in described.

Described steel loop 5 is stainless steel cylinder steel loops; This structure is convenient to steel loop 5 crush seal circles 6, also is convenient to card pressure pipe body 4, and simultaneously, it has corrosion proof function, connects unstable problem to prevent the connecting body that brings because of corrosion.

As shown in Figure 2, during installation, earlier seal ring 6, steel loop 5 are set in body 4 one ends successively, then, body 4 ends are inserted in the interior shoulder hole 2, and make the end of body 4 push up the inner end that is located at interior shoulder hole 2, then, adopt the internal shoulder hole of special-purpose ring-pressing tool 3 two ends to encircle pressure, ring card; Shoulder hole 3 opening ends sealed in special-purpose ring-pressing tool made, and make steel loop 5 crush seal circles 6, further make the space between seal ring 6 complete filling bodys 4 and the interior shoulder hole 3, simultaneously, steel loop 5 further encircles pressure pipe body 4 and body 4 is caved inward, in addition, interior shoulder hole 3 medial extremitys are depressed at special-purpose ring-pressing tool ring, and body 4 is also caved inward, and are final, shoulder hole 3, steel loop 5, seal ring 6 and body 4 are combined closely in making, and form the reinforced structure that connects and seal.

Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
