Description

Flange convenient to location

Technical Field

The utility model relates to the technical field of flanges, in particular to a flange convenient to position.

Background

The flange is used for connecting the device at the junction of two pipelines, through the tip at two flanges with the flange welding, later lead to the bolt installation with two flanges together to can be with the tip intercommunication of two pipelines together, it mainly plays a connected effect, if directly link together two pipelines, not only the leakproofness is not good, and the junction of pipeline is also comparatively easy oxidation damage.

The prior art scheme has the following problems when in use: the technology of flange and very ripe, but we found that when the flange was docked with the pipeline, the tiny gap that leaks appears in the welding mouth, and this is because the problem of welding master's technique, and welding master is in welding pipeline and flange department, because the location length butt joint of pipeline is insufficient, leads to the location to appear the error, and in order to reduce the melting degree of welding pipeline, therefore the welding department of pipeline is the welding completion, leads to long-time after using, welds thinner partial oxidation and appears corrosion leak.

Improvements to the above problems are needed to meet market demands.

Disclosure of Invention

The utility model aims to provide a flange convenient to position, so as to solve the problems that the flange technology proposed in the background technology is mature, but when the flange is butted with a pipeline, a tiny water leakage gap appears at a welding port, which is caused by the problem of a welding master technology, and the welding master is used for welding the pipeline and the flange, and the positioning error is caused by the insufficient butt joint of the positioning length of the pipeline.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a flange for facilitating positioning, comprising: the flange and mounting hole, the mounting hole has been seted up on the surface of flange, one side fixedly connected with butt joint of flange, the flange with the same side of butt joint still is provided with the outer lane, the outer lane sets up the outer wall department at the butt joint.

Preferably, the diameters of the inner wall of the butt joint and the inner wall of the flange are the same, and an annular gap is formed between the outer wall of the butt joint and the inner wall of the outer ring.

Preferably, an inner ring is fixedly connected to one side of the flange, which is far away from the butt joint, and the diameters of the inner ring and the flange are the same as those of the inner ring of the butt joint.

Preferably, the outer wall surface of the inner ring is provided with a groove, the inner ring is fixedly provided with a butt joint lug and a groove which are matched in size on the same side as the groove, and the butt joint lug and the groove are respectively and alternately distributed on the poles of the annular surface of the inner ring.

Compared with the prior art, the utility model has the beneficial effects that: this flange convenient to location, through mutually supporting between flange and the mounting hole, can pass the mounting hole through the bolt after two flanges are butt jointed each other, assemble two flanges together, and when flange and pipeline location butt joint, insert the gap department between butt joint and outer lane with the pipeline, can make the accurate butt joint of flange and pipeline through setting up butt joint and gap, afterwards weld the junction of butt joint and pipeline together with the welding machine, welder melts together through melting the surface of outer lane and pipeline during the welding, do not damage the structure of pipeline, afterwards will dock with pipeline welded flange, make butt joint lug on one flange and the recess on another flange rivet, thereby realize the quick positioning butt joint to the flange, again with the mounting hole on the bolt shuttle flange, and be in the same place with bolted connection, thereby realize the quick assembly to the flange, this scheme can not only realize the quick positioning butt joint with the pipeline through setting up the butt joint to the flange, and can reduce the welding consumption to the pipeline, thereby make the welding process flange more accurate life behind the more.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: a flange for facilitating positioning, comprising: the flange 1 and mounting hole 2, mounting hole 2 has been seted up on the surface of flange 1, one side fixedly connected with butt joint 3 of flange 1, flange 1 with butt joint 3 is same one side still is provided with outer lane 4, outer lane 4 sets up the outer wall department at butt joint 3.

Referring to fig. 1, the diameters of the inner wall of the butt joint 3 and the inner wall of the flange 1 are the same, and an annular gap is formed between the outer wall of the butt joint 3 and the inner wall of the outer ring 4, and when the flange 1 is in butt joint with a pipeline, the pipeline is inserted into the annular gap, so that the pipeline and the flange 1 can be quickly in butt joint.

Referring to fig. 2, an inner ring 5 is fixedly connected to one side of the flange 1 away from the butt joint 3, and the diameters of the inner ring 5 and the flange 1 are the same as those of the inner ring of the butt joint 3, so that water flow can pass through the inner ring 5, the flange 1 and the inside of the butt joint 3 smoothly.

Referring to fig. 2, a groove 7 is formed in the outer wall surface of the inner ring 5, a butt joint protrusion 6 is fixedly arranged on the same side of the inner ring 5 as the groove 7, the sizes of the butt joint protrusion 6 and the groove 7 are matched, the butt joint protrusion 6 and the groove 7 are respectively and alternately distributed on the poles of the annular surface of the inner ring 5, one flange 1 and the other flange 1 can be rotated by 90 degrees and then are in butt joint, so that the butt joint protrusion 6 and the groove 7 on the one flange 1 are riveted with the groove 7 and the butt joint protrusion 6 on the other flange 1, and the two flanges 1 can be quickly in butt joint with each other.

To sum up: as shown in fig. 1 to 3, when the flange convenient for positioning is used, firstly, the end of the pipe is butted with the flange 1 so that the end of the pipe is inserted into the gap between the butt joint 3 and the outer ring 4, then the outer ring 4 is melted by welding so that the outer ring 4 is welded at the end of the pipe so as to position the flange 1 and the pipe together, the method can avoid the condition that the pipe is thinned and easy to be damaged by oxidation caused by the melting of the pipe, after the flange 1 is butted together and welded, the flanges 1 at the end of the two pipes are butted so that the butt joint lug 6 and the groove 7 on the flange 1 are riveted with the groove 7 and the butt joint lug 6 on the other flange 1 together, and then the bolts pass through the mounting holes 2 on the two flanges 1 and are fixed together by nuts, thereby realizing the quick butt joint fixing between the flanges 1, which is the characteristics of the flange convenient for positioning.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
