Description

Corrugated pipe compensator with waterproof heat preservation function Technical Field The utility model mainly relates to the technical field of corrugated pipe compensators, in particular to a corrugated pipe compensator with waterproof and heat-insulating functions. Background The corrugated pipe compensator is one compensating element to absorb the size change of pipe, container, etc. caused by expansion and contraction, or to compensate the axial, transverse and angular displacement of pipe, container, etc. and has wide application in modern industry. Since the bellows compensator is often used for pipe compensation, the bellows compensator on the market at present is not ideal for the waterproofing and heat preservation effect during pipe compensation. The corrugated pipe compensator plays a role in compensating internal deformation and displacement through the middle corrugated pipe, is connected with a pipeline through the flanges at two ends, and is provided with a section of connecting pipe between the corrugated pipe and the flanges, so that the corrugated pipe is conveniently connected with the flanges. The corrugated pipe and the connecting pipe are generally fixed through welding, and as the corrugated pipe needs to adapt to the deformation in the pipeline, frequent deformation easily causes loosening or cracking of the connecting part of the connecting pipe and the corrugated pipe, and once the cracking occurs, rainwater is easily caused to permeate, so that the safety of an internal circuit is influenced.
