The outside of the upper balance tube is provided with a balance cavity outer cover tube, the balance cavity outer cover tube is connected with the left sealing cylinder through a left outer end ring, namely, the outer ring of the left outer end ring is welded on the inner wall of the left end of the balance cavity outer cover tube, and the inner ring of the left outer end ring is welded on the left sealing cylinder.
The right end of the outer cover pipe of the balance cavity is connected with a sealing cylinder, the sealing cylinder is in sliding contact with the balance pipe at the upper part, four annular sealing ring mounting grooves are also formed in the inner wall of the sealing cylinder, Y-shaped sealing rings with lip edges are mounted in the two annular sealing ring mounting grooves in the middle, and O-shaped sealing rings are mounted in the two annular sealing ring mounting grooves in the outer side.
The sealing cylinder is connected with the right outer end ring through a plurality of bolts, and the right outer end ring is welded on the outer wall of the right end of the right movable end pipe.
A plurality of round holes are distributed on the left end ring in the circumferential direction to ensure that liquid in the pipe can uniformly and stably enter a balance cavity of the compensator. The space formed between the left end ring and the outer cover tube of the balance cavity is the balance cavity.
The working process is as follows: the left end of the left end pipe of the device is connected with the pipeline, the right end of the right end pipe is connected with the pipeline, and when the left end pipe moves, the left end ring drives the cylindrical inner cover to move, and the right sealing cylinder is driven to slide on the right end pipe. When the right end pipe moves, the cylindrical outer cover moves through the right end ring, and the left sealing cylinder is driven to slide on the left end pipe.
The utility model has the advantages that: the non-thrust sleeve compensator can bear the internal pressure of a pipeline and absorb the internal pressure thrust of the pipeline by utilizing the medium pressure through the self structure, so that the fixed supports at two sides of the compensator only bear the friction force of the thermal displacement of the compensator and the friction force of the pipeline, and the load of the fixed support is greatly reduced. The device is mainly applied to pipe galleries or overhead pipe systems which are inconvenient for designing large fixed supports and can only absorb the axial displacement of the pipeline. The device has the advantages of compact design structure, good sealing performance, small friction force, low requirement on the fixed support and convenience for emergency maintenance.
