The compensator is generally made of austenitic stainless steel integrally formed corrugated pipe disturbing parts, to compensate the displacement and deflection of the pipeline due to thermal expansion and contraction. Expansion joints generally use sealing rings. Play a self-sealing role, and leave a gap between the pipe ends to compensate for the displacement and deflection of the pipe due to thermal expansion and contraction.
1. Retractor: Large expansion, high temperature, and strong pressure area. In the construction of water supply and drainage engineering, the foundation concrete is poured or embedded pipelines. When these engineering pipelines are affected by the building foundation settlement, equipment resonance, geological changes, and pipeline medium changes, the distribution position of the pipeline begins to be stressed, deformed, and twisted to damage the pipeline. The embedded pipeline even ruptures brings great inconvenience to the construction unit. In order to overcome these difficulties and ensure the safe operation of the pipeline, expanders and expansion joints are used: it can axially expand and contract within a certain range and overcome various angle shifts of the pipeline. Position, disagreement, expansion and contraction. The pipe can be freely stretched in the retractor. Once it exceeds the maximum amount of expansion and contraction, it acts as a limit. So as to ensure the safe operation of the pipeline.
2. Compensator: Silencer and mute pipe joints, which cannot bear weight and should be hoisted separately. It is mainly used for domestic water pump houses, central air-conditioning water pump units, fire-fighting equipment, which are relatively close to residential areas. It has high elastic ultimate tensile strength and absorbs axial, lateral and angular cold and heat deformation of pipelines. Absorb the vibration of water pump equipment and reduce the noise caused by equipment vibration. It is convenient to install and disassemble the valve pipeline.
