Description

TECHNICAL FIELD

[0001] The utility model relates to the field of gas pipeline, concretely relates to a corrugated compensator convenient to splice. BACKGROUND

[0002] The gas corrugated compensator is an important pipeline connecting equipment, plays a key role in the gas pipeline system, and is a compensating element mainly composed of a corrugated pipe, flanges and connecting pipes. The working principle of the corrugated compensator is based on its unique corrugated structure. When the pipeline is affected by external factors such as temperature and pressure, it will produce expansion, vibration and displacement. The corrugated compensator expands and deforms through the corrugated pipe inside, thereby absorbing and compensating these changes and maintaining the stability of the pipeline system. At the same time, the corrugated compensator also has a certain elasticity, which can effectively relieve pipeline vibration, reduce noise and improve the service life of the pipeline system.

[0003] According to the search, a utility model patent with the publication number CN202868186U specifically discloses a gas pipeline corrugated compensator, which comprises a corrugated compensation area composed of a plurality of corrugated pipes with welding rings at both ends and connectors connected at both ends of the corrugated compensation area. The connectors are welded with the welding rings at both ends of the corrugated compensation area. The outer side of the corrugated compensation area is provided with a tubular outer shield. The corrugated compensator with the above structure can not only protect the corrugated pipe from being damaged, but also effectively avoid the instability deformation of the product caused by stress during use.

[0004] The existing corrugated compensator needs to be connected with the gas pipeline during use, but the existing corrugated compensator adopts a flange connection mode for butt joint in order to ensure the stability of the connection. Although this mode can ensure the stability of butt joint to the greatest extent, it needs to be screwed during installation and disassembly, which causes time-consuming and labor-consuming during installation and affects the efficiency of installation and splicing.
