Abstract
The utility model relates to a pipeline jointing inner repaired mouth tie-in with an incorporated structure. The utility model comprises a columnar body and a positioning mechanism which is arranged on the outer middle of the columnar body, an airproof ring groove which goes along the circumference and is arranged on the outside which is near to the two ends of the columnar body and an airproof circle which is arranged in the ring groove. The columnar body is made of metal, and the positioning mechanism is an outer flange which has the same body with the columnar body. The utility model has the advantages that the positioning mechanism is designed to be a ring shaped flange which is incorporated with the positioning canister and therefore is easy to be processed and has accurate positioning; moreover, the utility model can fill the circumferential space of a whole pipe when the pipe is welded, which makes the welding work convenient; For adopting the stainless steel as a body, the utility model has the capabilities of high intensity and proof abrasion and is applicable for the transmitting pipes of the liquids with high temperatures or the sewage mud; the body of the common steel increases and strengthens the antiseptic metal plating layer and reduces the cost of the materials; the utility model suits for the welding of the different caustic liquid pipes by choosing different metal plating layers.
Description
Technical field
The utility model relates to a kind of pipeline welding internal mending orifice joint, is mainly used in being welded to connect between metallic conduit end and the end, is applicable to the welding between straight tube, threeway, many logical, the elbows.
Background technique
Existing pipeline welding internal joint patch main structure is tubular body and the circumferential several radially positioning rods or the silks of welding that are located at its outer middle side part, locates to be provided with along the closure gasket groove of circumference in the outside of this tubular body near two ends and is located at seal ring in this annular groove.Its shortcoming is the positioning rod or the location silk location inaccuracy of welding, is connected insecurely with main body, reserves gap greatly when pipeline dock, has increased the workload of welding.
Summary of the invention
The purpose of this utility model just provides a kind of pipeline welding internal mending orifice joint of integrative-structure, to solve the positioning means location inaccuracy that prior art exists, be connected insecurely with main body, when pipeline docks, reserve big gap, increased the problem of the workload of welding.
The technical solution of the utility model is: comprise tubular body and the position structure that is located at its outer middle side part, be provided with along the closure gasket groove of circumference in the outside of this tubular body near the place, two ends and be located at seal ring in this annular groove, it is characterized in that: described tubular body is made of metal, and described position structure is to be the outward flange of one with this main body.
Described tubular body and outward flange are made by stainless steel.
Described tubular body and outward flange are made by plain carbon steel or iron, in inboard, two ends and the outside closure gasket groove of this tubular body all with strengthening non-corrosive metal (NCM) coating.
Described closure gasket groove is narrow groove of rectangle or sipes, and the cross section of the seal ring corresponding with it is round, oval, square, oval or round rectangle.
Described outward flange can be continuous circular shape or discontinuous annular.
The utility model has the advantages that: it is the annular flange flange of one that positioning means is designed to tubular body, processing easily, and the location is accurately; And when welded pipe line, can fill the gap of whole pipe circumference, make things convenient for welding job; Adopt stainless main body to have intensity height, anti abrasive performance, be applicable to the conveyance conduit of high temperature fluid or mud and sewage; The main body of common iron and steel increases strengthens non-corrosive metal (NCM) coating reduction cost of material, by selecting for use different metal coating to be suitable for the welding of different corrosive fluid lines.

Fig. 3 and Fig. 4 are the sectional structure schematic representation that the utility model has coat of metal main body;
Fig. 5 is the schematic representation that the utility model is used.
Embodiment
Referring to Fig. 1～Fig. 4, basic structure of the present utility model comprises tubular body and is located at the position structure 2 of its outer middle side part, locates to be provided with along the closure gasket groove of circumference in the outside of this tubular body 1 near two ends and is located at seal ring 3 in this annular groove.Described tubular body 1 is made of metal, and described position structure 2 is to be the outward flange of one with this main body.The equal chamfering of interior angle at tubular body 1 two ends is to reduce the resistance of convection cell.
Described tubular body 1 and outward flange 2 are made (referring to Fig. 1 and Fig. 2) by stainless steel.Described closure gasket groove is narrow groove of rectangle (as shown in Figure 1) or sipes (as shown in Figure 2), also can be made up at interval by narrow groove and sipes, and the cross section of the seal ring 3 corresponding with it is round, oval, square, oval or round rectangle.
Described tubular body 1 and outward flange 2 also can be made by plain carbon steel or iron, all are coated with in inboard, two ends and the outside closure gasket groove 3 of this tubular body 1 with strengthening non-corrosive metal (NCM) coating 4.According to the fluid difference in the pipeline, optional usefulness has the different metal coating of corrosion resistance, as metals such as chromium, nickel.The structure of described closure gasket groove and seal ring 3 is identical with a last embodiment with setting.
Described outward flange 2 can be continuous circular shape (as shown in drawings) or discontinuous annular (not shown).
Referring to Fig. 5, the utility model in use, insert in two pipelines, the 5 phase line ups that need weld together at the two ends of its main body 1, two pipeline 5 phase line ups and outward flange of the present utility model 2 offset (effect of outward flange 2 is to make main body 1 enter equal in length in two pipelines), are welded to each other together with two pipe end places 6 that need weld together together with outward flange 2 then.
Claims (5)
