Abstract
The utility model relates to a pipeline jointing inner repaired mouth tie-in which is provided with a polyfluortetraethylene coat. The utility model comprises a columnar body and a positioning mechanism. An airproof ring groove which goes along the circumference is arranged on the outside at a position 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, polyfluortetraethylene coats are arranged on the inside and the two ends of the columnar body and in the airproof ring which is on outside of the columnar body, the positioning mechanism consists of a metal positioning canister and an outer flange which is arranged on the outer center of the metal positioning canister, the positioning canister is inserted in a concave ring which is arranged in the middle of the outside of the columnar body and a heat insulating layer is arranged between the positioning canister and the concave ring. 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; a heat insulting layer is arranged between the metal body and the positioning canister, thus preventing the overheating body from damaging the rotproof coat when people jointing; and the utility model adopts the common steel as a body, reducing the cost of the materials.
Description
Technical field
The utility model relates to a kind of pipeline welding internal mending orifice joint, is mainly used in to have being welded to connect between anticorrosion internally coated 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.In addition, main body adopts teflon to make the cost of material height.
Summary of the invention
The purpose of this utility model just provides a kind of pipeline welding internal mending orifice joint that has polytetrafluorethylecoatings coatings, to solve the positioning means location inaccuracy that prior art exists, be connected insecure with main body, when docking, pipeline reserves big gap, increased the workload of welding, and the high problem of cost of material.
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 is equipped with polytetrafluorethylecoatings coatings in inboard, two ends and the outside closure gasket groove of this tubular body; Described position structure is made of metal location cylinder and the outward flange that is located at its outer middle side part, and location cylinder is embedded in the scrobicular ring that is located at the outer middle side part of described tubular body, and between is provided with thermal-protective coating.
Described location cylinder and outward flange are split or integrative-structure, and this outward flange can be continuous circular shape or discontinuous annular.
The utility model has the advantages that: positioning means is designed to the annular flange flange with the location cylinder one, 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; Be provided with thermal-protective coating between metal master and the location cylinder, prevent when welding main body overheated and damage corrosion-inhibiting coating; Adopt the main body of common iron and steel can reduce cost of material.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 is an application schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises tubular body 1 and is located at the position structure of its outer middle side part, this position structure is made of metal location cylinder 2 and the outward flange 3 that is located at its outer middle side part, location cylinder 2 is embedded in the scrobicular ring that is located at described tubular body 1 outer middle side part, and between is provided with thermal-protective coating 4.Be provided with along the closure gasket groove of circumference in the outside of this tubular body 1 near the place, two ends and be located at seal ring 5 in this annular groove.Described tubular body 1 is made by metals such as steel, iron, is equipped with polytetrafluorethylecoatings coatings 6 in inboard, two ends and the outside closure gasket groove of this tubular body 1.The equal chamfering 7 of the interior angle at tubular body 1 two ends is to reduce the resistance of convection cell.
Described location cylinder 2 is split or integrative-structure with outward flange 3, and this outward flange 3 can be continuous circular shape (as shown in Figure 1) or discontinuous annular (not shown).
The utility model in use, insert in two pipelines, the 8 phase line ups that need weld together at the two ends of its main body 1, two pipeline 8 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 together with the gap 9 of outward flange 2 with two pipe ends that need weld together then.
Claims (2)
1. a pipeline welding internal mending orifice joint that has polytetrafluorethylecoatings coatings comprises 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 is equipped with polytetrafluorethylecoatings coatings in inboard, two ends and the outside closure gasket groove of this tubular body; Described position structure is made of metal location cylinder and the outward flange that is located at its outer middle side part, and location cylinder is embedded in the scrobicular ring that is located at the outer middle side part of described tubular body, and between is provided with thermal-protective coating.
