Abstract
The utility model discloses a pipe connecting device comprising two pipes connected with each other. A welded flange is arranged at a joint of one of the pipes, a boss structure is welded at the outer edge of a joint of the other pipe and is connectively matched with a lap joint flange, and the welded flange and the lap joint flange are fixedly connected through bolts. By the pipe connecting device, mounting of the pipes is more convenient.
Description
Technical field
The utility model relates to a kind of connection set, is specifically related to a kind of assembling pipe joint.
Background technique
Connection between the pipeline adopts flange to connect usually, and two piping flanges pass through bolt when connecting.In the prior art, flange adopts welded flange more, and namely flange is welded on the pipeline, when pipeline connects, the bolt hole of two pipelines need be aimed at and install.The situation that the fabricating yard is limited, the bolt connecting hole of flange are difficult to aim at, and cause the pipeline installation difficulty to increase.
The model utility content
The purpose of this utility model is to overcome above shortcoming, and a kind of assembling pipe joint is provided, and this connection set makes the installation of pipeline more convenient.
The technical solution of the utility model is:
A kind of assembling pipe joint, comprise interconnective two pipelines, the jointing of a described pipeline is provided with a welded flange, the outer rim of described another root pipe joint is welded with a frustum cone structure, described frustum cone structure is connected with a lap joint flange, and described welded flange and described lap joint flange are bolted to connection.
Further, the angle of the central shaft of described frustum cone structure and bus is 20 °-60 °.
Further, be provided with annular gasket between described welded flange and the described lap joint flange.
Further, described annular gasket is red cardboard.
The assembling pipe joint that the utility model provides has following advantage:
1, the assembling pipe joint that provides of the utility model makes the installation of pipeline more convenient.The assembling pipe joint that the utility model provides, comprise interconnective two pipelines, wherein, the jointing of a pipeline is provided with a welded flange, the outer rim of another root pipe joint is welded with a frustum cone structure, this frustum cone structure is connected with a lap joint flange, and described welded flange and described lap joint flange are bolted to connection.The assembling pipe joint that the utility model provides includes lap joint flange, in the pipeline installation process, by rotating lap joint flange, lap joint flange is aimed at the bolt hole of welded flange, has made things convenient for the installation of pipeline.
2, the assembling pipe joint that provides of the utility model, the processing of lap joint flange is simple, and is applied widely.The assembling pipe joint that the utility model provides, lap joint flange and a frustum cone structure are connected, and this frustum cone structure is connected with pipeline welding, be that frustum cone structure is fixed, the inner ring processing technology of lap joint flange is simple, and the inner ring size is applicable to different calibers, during fabrication, can only change the external diameter of lap joint flange, using scope is wide.
3, the assembling pipe joint that provides of the utility model, good airproof performance.The assembling pipe joint that the utility model provides is provided with pad between welded flange and lap joint flange, increase the sealing that pipeline connects.When pad was red cardboard, it was a kind of in the asbestos packing sheet that red cardboard belongs to, and compressive strength, heat resistance are good, further improve the sealing that pipeline connects.
