Description

Adjustable ripple compensator for pipeline Technical Field The invention relates to the technical field of compensators, in particular to an adjustable ripple compensator for a pipeline. Background Ripple compensators are one type of compensation element. The corrugated pipe adopts the effective expansion and contraction deformation of the corrugated pipe of the working main body to absorb the dimensional changes of pipelines, ducts, containers and the like caused by expansion with heat and contraction with cold or compensate the axial, transverse and angular displacement of the pipelines, ducts, containers and the like. And can also be used for noise reduction and vibration reduction. Has wide application in modern industry. The working principle of the corrugated pipe compensator is mainly that displacement of thermal expansion or contraction generated by temperature and pressure changes in a pipeline system is absorbed and dispersed through a corrugated structure in the corrugated pipe compensator, so that stress on the pipeline system is reduced, and the safe and stable operation of the pipeline system is protected. The inventor designs an adjustable corrugated compensator for pipelines, which solves the technical problems because excessive repeated shrinkage and stretching of a corrugated pipe part can cause excessive deformation and irrecoverable due to thermal expansion or shrinkage of the corrugated pipe compensator in a pipeline system caused by temperature and pressure changes, so that the corrugated pipe part is damaged and the service life of equipment is influenced. Disclosure of Invention The invention provides an adjustable ripple compensator for a pipeline, which solves the technical problem that the ripple compensator cannot be adjusted in time according to requirements. The adjustable corrugated compensator for the pipeline comprises a corrugated pipe body, an inner sleeve and two flange connection discs, wherein two ends of the corrugated pipe body are respectively welded with the two flange connection discs, an inner port of the corrugated pipe body is welded with the outer side of one end of the inner sleeve, corresponding protruding blocks are annularly arranged on the two flange connection discs, the corresponding protruding blocks are connected through an adjustable thread structure, an annular embedded groove is formed in a part, corresponding to inner side waves of the corrugated pipe body, of the annular outer side surface of the inner sleeve, and a special-shaped high-pressure air bag is clamped between the annular embedded groove and the inner side waves of the corrugated pipe body; The middle position of bellows body is provided with the enhancement portion, and dysmorphism high pressure gasbag and enhancement portion correspond the part and are provided with the air duct, and the air duct runs through enhancement portion and extends to the outside, installs manometer and relief pressure valve on the air duct in proper order. Preferably, the exhaust port of the pressure reducing valve is externally connected with pressure stabilizing equipment, and the pressure stabilizing equipment introduces high-pressure gas into the special-shaped high-pressure air bag through the pressure reducing valve.
