Abstract
The utility model provides a flange gasket with a circular structure formed by cutting flat plate material. At least one colloid material (2) circularly laid to form a closed ring is arranged on the circular flat plate body (1) and on a surface contacted with the end surface of a flange. The flange gasket is characterized in that the closed colloid material is laid on the sealing surface of the original flat plate gasket, the colloid material is elastic material such as synthetic rubber, resin type material and especially for various sealant, and the flange gasket is easier to be compressed and distorted under pressure when in use to achieve the sealing effect. Compared with the prior art, to compress the endless belt of the colloid material on the flat plate to distort is far easier to compress the flat plate to distort, therefore, the pressure required for the sealing effect is achieved, the pulling force for bolt fixing can be reduced, and the sealing effect is better.
Description
Technical field the utility model relates to a kind of flange gasket, belongs to the technical field of sealing technology in the mechanical engineering.
The background technique flange gasket is to use so that the part that two end face of flange joints are sealed, used gasket seal when comprising being connected of the used flange of various pipe joint and flange or flange and stifle, also comprise butt joint of casing jar groove and the used used pad of flange-like joint of capping, as the gear-box sealing gasket.When two flange end ends connected, pad was served as a contrast between two end faces, was subjected to the tension with the bolt of two flanges tension, and pad is compacted and cause distortion and closely contact with the both sides end face of flange, reached sealing effect.But the flange gasket of present use is the plate material cutting mostly to form, and elasticity leeway is little, and during especially as hot environment, flange material is wanted filling dottle pin temperature-resistant material and the elasticity deficiency.Therefore, flange gasket commonly used needs very big bolt tightening force, and perhaps tightness is not high.
Summary of the invention is at above-mentioned deficiency, and the utility model is exactly that a kind of flange gasket that its bi-side are the plane that changed will be provided, to improve sealability.
The flange gasket that the utility model provides, the loop configuration that has plate material to tailor to form on said annular flat plate body, has the colloidal materials of laying and constitute closed loop at least along annular on contacted with end face of flange.
The flange gasket that the utility model provides, on the sealing surface of former dull and stereotyped pad, laid the colloidal materials of sealing, said colloidal materials is the resilient material of synthetic rubber, resinae, especially various sealers, ratio is easier to be compressed distortion and reaches sealing effect when it is under pressure in use.Compared with prior art, the colloidal materials endless belt compressive strain on the flat board is will more dull and more stereotyped compressive strain own much easier, so it reaches the needed pressure of sealing effect, promptly the firm pulling force that provides of bolt can reduce, and sealing effect is better.
Description of drawings Fig. 1 is the utility model one embodiment's an axial sectional view, and Fig. 2 is the plan view of Fig. 1, among the figure: 1-flat body, 2-colloidal materials band.
Embodiment has the flat gasket 1 to have filled asbestos as shown in Figure 1, 2, and pad hand-held ear when an annulus and is installed synthesizes, and the concentric closed loop 2 with the rubber laying of three roads and annulus is respectively arranged on the annulus two sides.
Claims (1)
1, a kind of flange gasket, the loop configuration that has plate material to tailor to form is characterized in that on said annular flat plate body, and the colloidal materials of laying and constitute closed loop at least along annular is arranged on contacted with end face of flange.
