Waterproof anti-explosion cable sealing element

Abstract

The invention discloses a waterproof anti-explosion cable sealing element. The waterproof anti-explosion cable sealing element is characterized by comprising a first sealing tube and a second sealingtube, wherein the axis of the first sealing tube is overlapped with the axis of the second sealing tube; the first sealing tube is contacted and locked with the second sealing tube; the first sealingtube consists of a first front end and a first rear end; the second sealing tube is composed of a second front end and a second rear end; the second front end is provided with a protruding portion; alimiting cavity is formed between the protruding portion and the second front end; the limiting cavity extends in an axial direction of a second connecting tube; sealing glue is arranged in the limiting cavity; the first rear end is inserted into the limiting cavity; and the first rear end is connected with the second front end in an interference fit manner through the sealing glue.

Description

technical field [0001] The invention belongs to the field of cable sealing materials, in particular to a waterproof and explosion-proof cable sealing piece. Background technique [0002] With the development of society, the degree of electrification in many fields is increasing, and it is often necessary to pass cables or other pipelines through different partitions. In order to prevent the exchange of the medium on both sides of the spacer and maintain the medium pressure, temperature, composition stability and cleanliness of the required space, it is necessary to seal the place where the cable or pipeline passes. [0003] Currently, there are mainly the following problems: [0004] 1. The airtight performance of the existing cable seals is not enough, and water often penetrates into the seals and contacts with the cables, resulting in short circuits and potential safety hazards; [0005] 2. The existing cable sealing materials have low fire-proof and explosion-proof perf...

AI Technical Summary

Problems solved by technology

[0004] 1. The airtight performance of the existing cable seals is not enough, and water often penetrates into the seals and contacts with the cables, resulting in short circuits and potential safety hazards;

[0005] 2. The existing cable sealing materials have low fire-proof and explosion-proof performance, are not easy to replace, and have relatively single functions, and the service life of the materials is short. If they are not replaced in time, they will often cause safety hazards;

[0006] 3. The existing cable sealing modules are basically molded by high temperature curing, which is cumbersome and costly
