Anti-explosion high-pressure-resisting filling type compensator

Abstract

The invention discloses an anti-explosion high-pressure-resisting filling type compensator which comprises a rotation inner pipe, an outer casing pipe, a filling valve, a left baffle ring, a movable baffle ring, graphite sealing padding and an anti-explosion structure. The right end of the rotation inner pipe is provided with an outer protruding ring, and the outer protruding ring of the rotation inner pipe extends into an inner hole of the outer casing pipe from left to right. The left baffle ring is fixedly connected to the left end of the inner hole of the outer casing pipe, and the anti-explosion structure comprises an anti-explosion ring plate. The anti-explosion ring plate is fixedly connected to the left end face of the outer casing pipe, and the outer wall of the rotation inner pipe extending out of the left end face of the outer casing pipe is provided with a ring groove. The anti-explosion ring plate is inserted into the ring groove and in clearance fit with the ring groove. The anti-explosion high-pressure-resisting filing type compensator is further characterized in that a rolling support is arranged at the matched position of the left baffle ring and the outer wall of the rotation inner pipe, a steel ball is arranged between the left end face of the outer protruding ring of the rotation inner pipe and the right end face of the movable baffle ring, and the anti-explosion ring plate is of a split structure. The anti-explosion high-pressure-resisting filing type compensator is simple in anti-explosion structure, easy to manufacture, low in manufacturing cost, flexible in rotation, good in rotation stability, free of disassembly and maintenance, and capable of improving the pipeline operation efficiency.

Description

technical field [0001] The invention relates to a pipeline compensator, in particular to a filling type rotary compensator. Background technique [0002] At present, the rotary compensator used in the heat pipe network will have certain safety hazards when used in some high-temperature and high-pressure pipelines and pipelines with frequent temperature changes and strict prevention of leakage. When the step surface of the inner pipe is subjected to alternating stress for a long time When a fracture occurs, the inner tube will be separated from the outer tube under huge pressure, causing a safety accident. At present, the explosion-proof rotary compensator fixes the explosion-proof ring on the outer surface of the rotating inner tube, and then sets it on the explosion-proof ring to prevent the explosion-proof ring from falling off. The outer tube with different diameters constitutes an explosion-proof structure. Therefore, the explosion-proof structure of the prior art explo...
