Description

Technical Field

[0001] The utility model relates to the technical field of pipeline corrugated compensators, and more specifically to a stainless steel water pipe groove type pipeline corrugated compensator. Background Art

[0002] Pipe compensators are also called expansion joints or expansion joints. They are mainly used to compensate for the thermal expansion and contraction caused by temperature changes in pipes. If the pipe cannot expand or contract freely when the temperature changes, thermal stress will be generated inside the pipe. This stress must be considered in the pipe design, otherwise it is likely to cause the pipe to rupture and affect normal production. There are many types of pipe compensators, including pipe corrugated compensators. Commonly used pipe corrugated compensators are cumbersome and time-consuming to install, and most of the compensators are made of non-stainless steel, and their service life may not meet people's usage needs.

[0003] For example, announcement No. CN219082580U discloses a pressure-sealed leak-proof device for a corrugated compensator of a heating pipe, which includes a heating pipe, a corrugated compensator body and a ring plate sleeved on the corrugated compensator body. One end of the heating pipe is arranged on the inner side of the ring plate, an annular groove is provided on the inner wall surface of the ring plate, and a telescopic air bag is provided inside the annular groove.

[0004] It can be seen from the above-mentioned public scheme that the two ends of the corrugated compensator body are fixed by connecting flanges and bolts when connected. Since the construction workers manually rotate and fix the bolts one by one, it is not only time-consuming, but also increases the labor intensity of the construction workers, making the installation of the corrugated compensator body more cumbersome and time-consuming, reducing the assembly efficiency. In addition, the corrugated compensator body is made of non-stainless steel material. During use, when the medium flows through, the grooves formed inside the corrugated part are easily eroded by the medium and wear faster, which makes the corrugated part of the corrugated compensator body easy to wear through and leak, so that the service life of the corrugated compensator body is limited.
