Sliding sleeve structure

Abstract

The invention discloses a sliding sleeve structure for the convenience of controlling pipeline circulation. The sliding sleeve structure comprises a pipe body, a sliding sleeve, an outer thread, an inner thread, a rotary shaft, a slide block, a chute, a pressure block, a fixed plate, a seal ring, a fixed bar, a rotating rod, a supporting rod, a connecting rod, a fixed block and a spring. The sliding sleeve structure is simple in structure and convenient to operate. The seal ring moves as the sliding sleeve moves, so that liquid circulation in a pipeline is controlled favorably, and therefore,the operating convenience is improved, the operating difficulty is reduced and the work efficiency is improved. According to the sliding sleeve structure, the sliding sleeve is fixed favorably as therotary shaft rotates, so that the problem that the sliding sleeve which is used cannot be fixed is solved. By fixing the sliding sleeve, liquid circulation in the pipeline is avoided, so that the pipeline liquid is controlled favorably and the workload of an operator is reduced favorably.

Description

technical field [0001] The invention relates to a sliding sleeve device, in particular to a sliding sleeve structure, and belongs to the technical field of sliding sleeve application. Background technique [0002] Sliding sleeves, usually used in building basements, are iron rings used to protect pipes or facilitate pipe installation. The classification of the casing includes rigid casing, flexible waterproof casing, steel pipe casing and iron casing, etc. The flange is placed on the pipe end by using a flanging, a steel ring, etc., and the flange can move on the pipe end. The ring or flanging is the sealing surface. The sliding sleeve is suitable for the connection of steel, aluminum and other non-ferrous metals and stainless acid-resistant steel containers and corrosion-resistant pipelines. The movable flange is generally matched with the water supply and drainage fittings. Most common at festivals. [0003] At present, the sliding sleeves on the market are mainly used f...

AI Technical Summary

Problems solved by technology

[0003] At present, the sliding sleeves on the market are mainly used for the protection of pipelines, and can also be used for the connection between pipelines. However, for sliding sleeves, it is inconvenient to use because the pipeline needs to control the flow of liquid in the pipeline; and the sliding sleeve The sleeve is not easy to fix when moving, resulting in an increase in the operation process
