Background technique
Sealing element be prevent fluid or solia particle from leak and prevent between adjacent faying face introduced contaminants such as dust with
Moisture etc. invades the material or part of the components inside machinery equipment.The storage room temperature of sealing element is preferably at 30 DEG C hereinafter, keep away
Exempt from sealing element and generate high temperature ageing, though rubber-plastic sealing part is small, its effect makes it national defence, chemical industry, petroleum, coal, friendship
Basic components and accessory in the national economy main industries such as logical transport and machine-building, occupy quite in the national economic development
Consequence, the production of rubber seal products and quality were progressed into a new stage, new period.But only
These be also far from satisfying other industry developments all kinds of rubber seal products are standardized, the needs of tandem product, especially
It is compared with international advanced country, China's product has sizable difference no matter in product quality, or in terms of product variety
Away from.
On the basis of the technical conditions of existing bellows seal, in the range used and convenience of sealing element
On still remain many deficiencies, most of service life is shorter under the stronger environment of corrosivity, is easy to be corroded, influence
Normal use, while during use, inner sealing is poor, is easy to happen leakage situation.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and is provided a kind of suitable for strong corrosive
The teflon bellows seal of environment can effectively improve the use scope and convenience of sealing element, the sealing element
For corrosion resistance teflon bellows seal, it is specific to liquid corrosive substance and is designed, it can be various again
Corrosivity coal quality in show lasting fault-free and high-performance designs, of simple structure and strong practicability.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of teflon bellows seal suitable for severe corrosive environment of the utility model, including sealed body,
One end of the sealed body is provided with corrosion-resistant outer ring, and the outer surface of the corrosion-resistant outer ring is provided with the surface layer EPIL, institute
State and be provided with inner ring on the inside of corrosion-resistant outer ring, the side of the corrosion-resistant outer ring is provided with becket, the becket with it is resistance to
It is provided with connecting bolt between corrosion outer ring, inside one end of the sealed body is provided with monomer sealing ring, and the monomer is close
The side of seal ring is provided with O-ring seal, and the side of the O-ring seal is provided with rotating ring, and the side of the rotating ring is provided with
Spring base, the spring base are internally provided with spring.
As a kind of optimal technical scheme of the utility model, the corrosion-resistant outer ring passes through connecting bolt phase with becket
It is fixed.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model is a kind of teflon bellows seal suitable for severe corrosive environment, can effectively be mentioned
The use scope and convenience of highly dense sealing, the sealing element are corrosion resistance teflon bellows seal, are special needles
Liquid corrosive substance is designed, lasting fault-free and high-performance can be shown in various corrosivity coals quality again
Design, of simple structure and strong practicability.
