Pipeline sealing element for engineering machinery

Abstract

The invention discloses a pipeline sealing element for engineering machinery. The pipeline sealing element comprises a first connecting piece and a second connecting piece, wherein the first connecting piece and the second connecting piece are respectively arranged on two groups of butted pipelines; the first connecting piece comprises a sleeve; a first inserting pipe is arranged in the sleeve; the first inserting pipe is communicated with the pipelines, and a gap is reserved between the first inserting pipe and the sleeve; the second connecting piece comprises a second inserting pipe; the second inserting pipe is inserted into the gap between the first inserting pipe and the sleeve in a sealing manner; a notch allowing the first inserting pipe to be in butt joint in a sealing manner is formed in the inner wall of the second inserting pipe in a concave mode; edge plates are arranged at the connecting ends of the first connecting piece and the second connecting piece; the end, away fromthe second connecting piece, of the sleeve is vertically sleeved with a first fixing piece; and the pipeline, located at the rear end of the second connecting piece, is sleeved with a second fixing piece. The pipeline sealing element for engineering machinery has high sealing performance and protection performance, is more stable and is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of seals, and in particular relates to a pipeline seal for engineering machinery. Background technique [0002] The seal is a material or part that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from intruding into the internal parts of the machine equipment. The storage room temperature of the seal is preferably below 30 degrees. Avoid Seals undergo high temperature aging. [0003] The patent with the application number 201811496209.6 discloses a pipeline elastic seal, including an upper fixing part and a lower fixing part. The bottom end of the upper fixing part is fixed with a first sealing ring, and the first sealing ring is away from the upper fixing part One side is fixedly provided with an elastic tube, the lower fixing part is movably arranged under the upper fixing part, the top of the lower fixing part is fixed...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned scheme is subjected to torsion forces in different directions, the joints of the two sets of butt joint pipes are likely to loosen, resulting in leakage. The stability performance is not high, and there is no good protection performance. Therefore, further improvement is needed
