Problems solved by technology

[0002] At present, in the hydraulic and pneumatic mechanical products in the machinery manufacturing industry, some parts and components need to be sealed with seals. The common seals in the market include O-shaped seal rings and sheet seals, which are usually made of rubber, steel paper, asbestos, etc. And other sealing materials, due to the simple shape and structure, the effect is not ideal when sealing, especially when used in the sealing of high-temperature, high-pressure hydraulic and pneumatic mechanical products and the sealing between relative moving parts, often due to sealing It is not good, and oil leakage and air leakage occur, which not only affects normal work and pollutes the environment, but also wastes materials and energy
In recent years, in order to solve this old, big, and difficult problem, people have conducted a lot of research on the materials used, and applied many new materials, and have also received certain results. However, due to the limitation of its simple structure, Oil and gas leaks are still common

Embodiment Construction

[0019] figure 1 Shown is the front view structure schematic diagram of the present invention.

[0020] figure 2 Shown is that the present invention is one of embodiment, is to connect the sealing member 6 of metal tube at the mouth of the compressed air line valve 5, and install the sleeve type seal made of latex in the mouth of the outer tube 7 that is discharged. Part 1, one end of the casing type seal 1 is a flange seal body 2, and the other end is a straight tube seal body 4, and the flange-shaped seal body 2 and the straight tube-shaped seal body 4 are integrated by an arc surface transition For a hollow sleeve type seal 1, the sealing surface between the discharged outer tube 7 and the flange sealing body 2 is concave on the flange surface, and the end surface of the discharged outer tube 7 is convex to form a convex-concave sealing surface 3, and the metal The sealing end of the pipe seal 6 is inserted into the straight pipe seal body 4 of the casing seal 1, and the ...

Abstract

The sleeve type seal piece has a sealing flange in one end, a sealing straight pipe in the other end and an arced or rectangular transition body in between, and is made of rubber or latex material. The sealing flange can realize single-side and double-sided sealing, and the sealing straight pipe has straight pipe and matched pipe or rod part. The present invention has double sealing structure, high sealing performance, convenient installation and maintenance and other advantages, and may be used in mechanical product with high liquid or gas sealing requirement.
