Abstract

The invention belongs to the technical field of compensators, in particular to a pressure compensator. The pressure compensator includes a body, which includes a bellows and a connecting seat; there is an annular groove between every two adjacent corrugations on the bellows, and the connecting There are multiple threaded holes on the seat; steering knuckle, screw, ball seat and rubber pad are arranged on the outer ring of the body; the steering knuckle is connected to the body, and a screw is connected to each end of the steering knuckle; the screw is connected through a bearing On the steering knuckle, a multi-section rope is evenly wound on the lead screw, and a ball seat is provided at one end of the lead screw near the connecting seat, and the ball seat is fixedly connected to the connecting seat; the rubber pad is stuck in the annular groove, and the two sides of the rubber pad Each end of the two ropes is fixedly connected to one end of each of the two ropes, and the other ends of the two ropes are respectively wound on the lead screw; through the cooperation between the steering knuckle, the lead screw and the rubber pad, the rubber pad cushions the axial pressure.

Description

technical field [0001] The invention belongs to the technical field of compensators, in particular to a pressure compensator. Background technique [0002] Compensators are also called expansion joints or expansion joints, which are composed of bellows and end pipes, brackets, flanges, conduits and other accessories that constitute the main body of the work. Deformation, to absorb the dimensional changes of pipelines, conduits, containers, etc. due to thermal expansion and contraction, or to compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc.; it can also be used for noise reduction and vibration reduction; in It is widely used in modern industry; in heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heated up, it is necessary to install a compensator on the pipe to compensate for the thermal elongation of the pipe, thereby reducing The ...
