Problems solved by technology

However, this pipe welding counterpart with gasket parts is not suitable for small diameter pipe welding
This is due to the narrow radial space in the welding of small-diameter pipes, so it cannot be installed into the pipe welding counterpart with complex structure.
At present, in the welding process of small-diameter pipes, no mature liner device has been developed

Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing:

[0033] Depend on Figure 1 to Figure 15 As shown, what the present invention develops is a liner device used during welding construction of small-diameter pipelines. The structure of the device is relatively simple, and it is easy to disassemble and assemble during the pipeline welding process.

[0034] The technical solution adopted by the present invention to solve its technical problems is: the device consists of a sealing plug, a gasket pressure ring, an annular gasket, a gasket support tube, a crowbar bracket, a crowbar wrench, a support push ring, and a long connecting cylinder , push-pull handle, ten main parts of the air compressor, and common and standard parts such as pin shafts and jacking screws.

[0035] The sealing plug is used to block the front end of the long connecting cylinder, and is in the shape of an externally threaded cylinder, with a small section ...

Abstract

The invention discloses an annular gasket device for small-caliber pipe welding; and the annular gasket device improves the welding quality during welding of small-caliber pipes. The device is characterized by further comprising a sealing screw plug, a gasket pressing ring, an annular gasket, a gasket support cylinder, a pry rod bracket, a pry rod spanner, a support push ring, a long connecting cylinder, a push-pull handle and an air compressor; the sealing screw plug is used for blocking the front end of the long connecting cylinder; the gasket pressing ring is used for pressing the annular gasket; the annular gasket is used for blocking a welding groove part; an outer wall of the gasket support cylinder is used for mounting the annular gasket and the gasket pressing ring, and an inner wall is used for mounting on the long connecting cylinder; the pry rod spanner is used for pushing the support push ring after welding; the support push ring is fixed on the long connecting cylinder through a jackscrew standard piece; the long connecting cylinder is used for mounting the sealing screw plug, spraying cooling air, mounting the push-pull handle and connecting with a rubber pipe of theair compressor; and the push-pull handle is used for blocking a tail channel of the long connecting cylinder.

Description

technical field [0001] The present invention relates to a device used in welding operations, in particular to a gasket device used in the welding of small-diameter pipelines. Background technique [0002] The application of welding backing can greatly improve the welding quality. At present, pipe welding counterparts with gasket parts have been developed at home and abroad, and the gasket technology is applied to the welding process of large-diameter pipelines. But, this pipe welding counterpart that has liner parts is not suitable for small-diameter pipe welding at present. This is due to the narrow radial space in the welding of small-diameter pipes, so it cannot be loaded into pipe welding counterparts with complex structures. At present, in the small-diameter pipeline welding process, no mature liner device has been developed. Contents of the invention [0003] In order to solve the technical problems mentioned in the background technology, the present invention pro...
