Problems solved by technology
[0002] The injection-filled sleeve compensator is called a tubular expansion joint, which is a compensation device for thermal fluid pipelines. It is mainly used for the auxiliary installation of straight pipelines. When used in sliding motion, it does not have guiding and anti-lateral stable sliding use, and does not have a double-seal filling structure, which is not convenient for efficient sealing, reliable and durable use of the pipeline in the running state, so a double-seal filling is required Type sleeve compensator to improve the above problems

The invention relates to the technical field of filling type sleeve compensators, in particular to a double-seal filling type sleeve compensator, which comprises an outer sleeve, a first sealing filler, a sealing crimping pipe fitting, a sliding sleeve, a second sealing filler and a guide connecting rod, wherein the bottom end of the outer sleeve is equipped with a first connecting flange plate; the top end of the outer sleeve is equipped with a second connecting flange plate; the sealing seat is arranged on the inner wall of the outer sleeve; the first sealing filler is arranged on the top ofthe sealing seat; a sealing pressure ring is arranged on the top of the first sealing filler; and the sealing crimping pipe fitting is mounted on the top of the sealing pressure ring; and the top endof the sealing crimping pipe fitting is equipped with a third connecting flange plate. The whole device is simple in structure, and when used in sliding motion, the filling type sleeve compensator has guiding and lateral stable sliding preventing functions; and meanwhile, a double-seal filling type structure is adopted, so that the pipeline is efficiently sealed in an operation state, reliable and durable to use and high in stability and practicability, and has a certain popularization value.
Description
technical field [0001] The invention relates to the technical field of injection-filling sleeve compensators, in particular to a double-seal injection-filling sleeve compensator. Background technique [0002] The injection-filled sleeve compensator is called a tubular expansion joint, which is a compensation device for thermal fluid pipelines. It is mainly used for the auxiliary installation of straight pipelines. When used in sliding motion, it does not have guiding and anti-lateral stable sliding use, and does not have a double-seal filling structure, which is not convenient for efficient sealing, reliable and durable use of the pipeline in the running state, so a double-seal filling is required Type sleeve compensator to improve the above problems. Contents of the invention [0003] The object of the present invention is to provide a double-seal injection sleeve compensator to solve the problems raised in the above-mentioned background technology. [0004] To achieve ...
