Abstract
The utility model discloses a welded tube fitting, which comprises a tube fitting body and strip-shaped indicating marks positioned on the outer wall of the tube fitting body, wherein the tube opening of the tube fitting body concaves inwardly from the outer wall of the tube fitting body to the inner wall of the tube fitting body to form an inner concave surface, so that the melt residue generated when a tubular product is welded with the welded tube fitting with the plane tube opening in the prior art is avoided. The welded tube fitting provided by the utility model has simple structure, convenience in use, and capability of highlighting the unique marks.
Description
Technical field
The utility model belongs to the pipe-line system field, relates in particular to a kind of fusing type pipe fitting.
Background technique
Pipe fitting is used to connect each tubing system in pipe-line system, mainly contain effects such as connection, control, support, and the fusing type pipe fitting is a kind of pipe fitting that the mode through sweat soldering is fixedly connected with tubing.
Existing fusing type pipe fitting generally comprises pipe fitting body 1 and the bar shaped sign 4 that is positioned at pipe fitting body 1 outer wall, and the mouth of pipe of pipe fitting body 1 is a plane, and is as shown in Figure 1, and in sweat soldering, the tubing 2 that can cause and the melt of fusing type pipe fitting overflow.After cooling, it is residual that the joint of tubing 2 and fusing type pipe fitting has melt, and the utmost point is not attractive in appearance.
Summary of the invention
The utility model provides a kind of fusing type pipe fitting simple in structure, easy to use, specious.
A kind of fusing type pipe fitting; Comprise pipe fitting body and the bar shaped sign that is positioned at pipe fitting body outer wall; The mouth of pipe of described pipe fitting body is recessed to form inner concave from pipe fitting body outer wall to the pipe fitting inner body wall, the melt residual condition that produces during the fusing type pipe fitting sweat soldering that solved the tubing and the existing plane mouth of pipe.
Described pipe fitting body outer wall is provided with the convexity of band bar-shaped trough.
Described bar-shaped trough and bar shaped sign are on same the straight line, the position indication when being used for tubing and being connected with pipe fitting, and can show the function of pipe fitting, like direct, elbow, threeway etc.
The shape of described convexity can be varied, considers the shape of preference rule from the angle that is easy to process, and is square such as square, rectangular etc., perhaps circle.
Described inner concave can be inner concave arc surface or inclined-plane.
When the utility model fusing type pipe fitting is connected with tubing, can utilize the mode of sweat soldering that both are fixed easily, and pipe fitting can be saved material; Also can solve the melt residual condition that when welding, exists, after the welding, the inner concave of the pipe fitting mouth of pipe is designed with sufficient space and holds the melt that overflows; Make product specious clean; The convexity of pipe fitting also is different from existing indicating structure, and is both attractive in appearance, can highlight unique sign again.
Description of drawings
Fig. 1 is existing fusing type pipe fitting and tubing assembled construction schematic representation;
Fig. 2 is the structural representation of the utility model fusing type pipe fitting;
Fig. 3 is the assembling schematic representation of the utility model fusing type pipe fitting and tubing.
Embodiment
As shown in Figures 2 and 3; A kind of fusing type pipe fitting of the utility model; Comprise pipe fitting body 1 and the bar shaped sign 4 that is positioned at pipe fitting body 1 outer wall; The mouth of pipe of pipe fitting body 1 is recessed to form the inner concave 5 that is inner concave arc surface or inclined-plane from pipe fitting body 1 outer wall to pipe fitting body 1 inwall, the melt residual condition that produces during the fusing type pipe fitting sweat soldering that solved tubing 2 and the existing plane mouth of pipe.
Protruding 6 shape can be varied, considers the shape of preference rule from the angle that is easy to process, and is square such as square, rectangular etc., perhaps circle, circular.
When the utility model fusing type pipe fitting uses, fusing type pipe fitting and tubing 2 employing welders are carried out sweat soldering, respectively fusing type pipe fitting and tubing 2 are put into the die head of welder; Fuse respectively, fusion finishes, and fusing type pipe fitting and tubing 2 is taken out assembled respectively; At this moment, the mouth of pipe and fusing type pipe fitting that tubing 2 inserts pipe fitting body 1 at high temperature all melt at the socket joint position, then tubing 2 and fusing type pipe fitting are assembled; The sign 4 of fusing type pipe fitting should be on same the straight line with the index line 3 of tubing 2 during assembling; When tubing 2 was inserted in the mouth of pipe of fusing type pipe fitting, fusing type pipe fitting and tubing 2 had carried out welding under the effect of heat temperature; And the melt that fusing type pipe fitting and tubing 2 produce can overflow along fusing type pipe fitting or tubing 2 towards periphery; Can be used for holding the melt that overflows and the inner concave 5 of the utility model fusing type pipe fitting is designed with sufficient space, make product specious, the circular protrusions 6 of pipe fitting body 1 outer wall also is different from existing sign 4; Both attractive in appearance, can highlight unique sign again.
