Description
Technical field
The present invention relates to a kind of expansion joint, more precisely, being a kind of zero leakage non-metal expansion joint.
Background technology
Expansion joint is as a kind of elastic compensation element that can freely stretch, with reliable operation, functional, compact conformation
The advantages of, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The expansion joint used on container, there is diversified forms, with regard to ripple
For the shape of line, apply the most extensive with U-shaped expansion joint, secondly also have Ω shapes and C-shaped etc..And used on pipeline it is swollen
Swollen section is divided into universal, pressure balance type, hinge type and Universal connector hair style etc. again for structure compensation.Expansion joint is general
It is connected by the flange at two ends with pipeline, flange and pipeline enclosure can set packing ring to prevent from revealing centre, but packing ring is long-term
Easy weathering and then expansion joint is caused to leak after use.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of zero leakage nonmetallic expansion
Section.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of zero leakage non-metal expansion joint, comprising a bellows, one end of the bellows is provided with one first connector, described
The other end of bellows is provided with one second connector, and the structure of first connector and the second connector is identical, includes a method
Blue piece, the flange plate is connected with bellows, and the edge of flange plate is to being externally provided with a tubular hooking ring, tubular hooking ring and method
Blue piece is integrally formed, and tubular hooking ring is made up with flange plate of high-strength engineering plastic, close to flange plate in tubular hooking ring
One end is provided with an aluminium backing, is provided with a rubber sheet gasket on the outside of aluminium backing, and rubber sheet gasket is externally provided with a stainless steel gasket, aluminium backing,
Rubber sheet gasket and stainless steel gasket are mutually bonded, and a rubber flange, the surface of rubber flange are additionally provided with tubular hooking ring inwall
For arc.
As preferred embodiments of the present invention, the thickness ratio of described aluminium backing, rubber sheet gasket and stainless steel gasket is 2：
3：2.
As preferred embodiments of the present invention, described rubber sheet gasket is made up of fluorosioloxane rubber.
The zero leakage non-metal expansion joint of the present invention connects even closer with pipeline, and rear rubber sheet gasket is fixed with screw rod
The space of sealed expansion joint and pipeline enclosure is deformed upon, the aluminium backing and stainless steel gasket of rubber sheet gasket both sides are more wear-resisting, right
Aluminium backing plays more preferable protective effect, and then substantially increases the sealing of expansion joint, realizes zero leakage.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
