Sealing device applied to hydraulic tubes and provided with self-luminescent function

Abstract

The invention discloses a sealing device applied to hydraulic tubes and provided with a self-luminescent function and mainly relates to the technical field of sealing devices of hydraulic tubes. A sealing module is arranged in each of a first frame, a second frame, a third frame and a fourth frame; three sealing modules which are arranged in parallel are arranged in each of a fifth frame and a sixth frame; five sealing modules which are arranged in parallel are arranged in a seventh frame; a self-luminescent layer is coated on the surface of a fastening frame and is made of a long-afterglow luminescent material; a layer of high-hardness heat-resistant paint is coated on the surface of the fastening frame; a protection layer is arranged on the surface of the fastening frame and is composedof an acid and alkaline corrosion-resistant layer, a high temperature-resistant layer and an abrasion-resistant layer. The sealing device is flexible and convenient to use, assemble, disassemble and maintain, high in sealing quality, excellent in universality, long in service life and wide in application range.

Description

technical field [0001] The invention relates to the technical field of sealing devices for hydraulic pipes, in particular to a sealing device for hydraulic pipes with a self-illuminating function. Background technique [0002] In the fields of buildings or ships, there will be a large number of pipelines such as electrical conduits, wire cores, supply pipes, discharge pipes, water pipes, hydraulic pipes, etc., which need to be installed through the walls or partitions of these structures. In order to ensure the sealing of the perforation of the wall or partition and protect the laid pipelines, the industry usually uses elastic pads with through holes to cover the pipelines, and the outside of the pad is a frame that is accommodated in the wall or partition In order to maintain the tightness between the wall or partition perforation and the pipeline passing through it, and protect the pipeline from fire, smoke, gas or water. [0003] In recent years, with the continuous de...

AI Technical Summary

Problems solved by technology

[0004] 1. Poor versatility, small scope of application, unable to meet the sealing requirements of hydraulic pipes of different quantities and specifications, and has a short service life;

[0005] 2. It is very troublesome to use, install, disassemble and maintain, and it is easy to loosen each other, and the sealing effect is average;

[0006] 3. The use, loading, unloading and maintenance are complex and cumbersome, and the maintenance cost is high
