A kind of pipe line via hole protector

Abstract

The invention relates to a pipeline passing hole protection piece which comprises a pipe body with a hollow structure, wherein an outer sealing ring is arranged on the pipe body; the left side of the outer sealing ring is an outer extending part; the right side of the outer sealing ring is provided with a pipe penetrating part; the outer extending part is provided with a first reversed tooth region; a second reversed tooth region and a third reversed tooth region are respectively arranged on the pipe penetrating part; the tooth directions of the first reversed tooth region and the se cond reversed tooth region face to the outer sealing ring; the tooth directions of the third reversed tooth region and the second reversed tooth region are the same; the pipe body between the third reversed tooth region and the second reversed tooth region is an empty tooth section. The protection piece disclosed by the invention can be firmly clamped on a to-be-passed piece, and an inner line can be protected for a long time; furthermore, the pipeline passing hole protection piece is easy to assemble in a construction process.

Description

technical field [0001] The invention relates to the field of protection parts, in particular to a protection part for pipeline passage holes. Background technique [0002] At present, with the improvement of science and technology, high-end electronic instruments, high-precision numerical control systems, and high-tech electronic information transmission and processing systems have been continuously developed and researched, and quickly applied to various production fields. Among them, transport vehicles (buses, Vans, trucks) and large equipment are most widely used. [0003] Transportation vehicles (passenger cars, trucks, trucks) and large-scale equipment belong to the means of production. As long as they are produced and operated to ensure the normal production of the enterprise, these means of production must ensure that the equipment is in good condition and operate normally. Therefore, the operating indicators of various systems inside the equipment And the operating ...

AI Technical Summary

Problems solved by technology

A large number of failure modes and various accidents (oil leakage, water leakage, air leakage, signal loss (disorder), unexpected power failure, circuit insurance burning, etc.) have proved their harmfulness. The above failure modes can cause equipment alarms and affect other equipment. The normal operation of the components will cause the equipment to stop running, and at the same time cause related major accidents, such as traffic paralysis, factory power outage, electric furnace explosion, etc.

[0007] The traditional method to solve the wear or scratch of the pipeline is to use ordinary rubber rings to be stuck on the cross-section of the opening. Convenient, the inner hole of the apron is much larger than the pipeline that will pass through, and after the pipeline passes through, a large cavity will be formed between the pipeline and the apron, which will bring greater difficulties to the subsequent foam sealing; because the apron It is made of rubber, and its aging resistance is greatly affected by the environment, especially in the environment of contact with oil and high temperature, the performance is the worst; the rubber material and sharp edges (edges) are not wear-resistant, easy to scratch, resulting in barrier failure; The friction coefficient between the ring and the surface of the pipeline is small. When the pipeline passes through, the rubber ring is easy to be taken out. After foaming in the later stage, this part is completely buried. The specific reliability of the inside cannot be verified and inspected after production.
