Description
Technical field
The present invention is a kind of environmentally friendly heat-insulating material sealing gasket, belongs to sealing gasket field.
Background technology
Gasket seal, as long as it is that a kind of place for having fluid for machinery, equipment, pipeline is used with sealing spare part,
Using inside and outside, the material to seal.Gasket seal is with metal or nonmetallic tabular material, cleaved, punching press or sanction
The technique such as cut to be made, for the sealed connection between pipeline, the sealed connection between the parts and parts of machinery equipment.By material
Metallic packing and nonmetallic gasket seal can be divided into.Metal has copper backing, stainless steel gasket, iron gasket, aluminium backing etc..
Nonmetallic has asbestos washer, non-asbestos pad, paper gasket, rubber sheet gasket etc..Asbestos-packing gasket using asbestos fibre, rubber as
Primary raw material is aided with rubber chemicals and inserts again, is made by processes such as mixing, hot-rolling shaping, vulcanizations.Asbestos rubber
Glue gasket can be divided into common asbestos-packing gasket and oil resisting paronite pad according to the difference of its formula, processing performance and purposes
Piece.Temperature and pressure difference according to using can be divided into low pressure asbestos rubber sheet gasket, middle pressure asbestos-packing gasket and high pressure stone
Cotton rubber sheet gasket.Suitable for the sealing of water, vapor, oils, solvent, intermediate acid, alkali, asbestos washer be mainly used in, it is low
In the sealing of pressure flange connection.Non-asbestos pad (no asbestos washer) is with the organic fibers such as aramid fiber and string and butyronitrile rubber
The encapsulant that glue, inorganic mineral roll at high temperature, due to seldom containing asbestos fibre, it is applicable the nothing for asbestos washer
The substitute products of asbestos washer.Non-asbestos pad (no asbestos washer) both has higher intensity, has preferable resilience again,

The stress caused by the sealing rubber of rubber ring and the joint interface of metallic plate, prevents sealing from being shelled with rubber from metallic plate
From, cracked in sealing with rubber near the end of metallic plate.In sealing rubber in the sealing gasket rubber ring
The end face embedment of outer circumferential side and the hole edge department of bonded metal plate, the sealing are included with rubber：Having for inner circumferential side seals
The 1st bellying in most thick portion, the composition adhesive portion Nian Jie with metallic plate outer circumferential side the 2nd bellying and the 1st and the 2nd
Recess between bellying.2nd bellying and recess have when by the face pressure contracting rubber ring of grip seal pad not with clamping
The thickness of the face contact of the sealing gasket.The front end of metallic plate is located at：Tilted in the range of recess, in two bellyings towards recess
Inclined-plane become from the curved surface convex relative to outside and turn between change point P1, P2 relative to the curved surface of outer concave.It is but existing
Equipment elasticity is poor, and damage is may result in the case where pressure is larger.
