Abstract
The utility model discloses a stainless steel sealing gasket. The stainless steel sealing gasket comprises a rubber sheet and a stainless steel gasket which are tightly bonded, wherein the stainless steel gasket is larger than the rubber sheet; both the rubber sheet and the stainless steel gasket are annular, and an opening is formed in the centers of the rubber sheet and the stainless steel gasket respectively and allows a bolt to penetrate; and the center hole of the rubber sheet is smaller than that of the stainless steel gasket, and the rubber sheet is in interference fit with the bolt. The stainless steel sealing gasket can enhance the air tightness and has the technical effects of vibration prevention, corrosion prevention, and the like.
Description
Technical field
The utility model relates to a kind of gasket seal, particularly a kind of stainless steel gasket seal.
Background technique
In mechanical seal type approval test platform, gasket seal is generally adopted in the sealing of each component of Seal cage.Existing gasket seal is exactly the iron plate on a plane usually, has the hole between wherein.More and more wider along with total type of test(ing) medium; Requiring of sealing technique is increasingly high; It not only will have the performance of anti-general clear water now, also technique effects such as tightness, vibrationproof, corrosion protection will be arranged, so need do brand-new selection and design to the material and the structure of Sealing.
The model utility content
The utility model is the defective that exists in the above existing technology in order to overcome; A kind of improved stainless steel gasket seal is provided; The sealing pad comprises: sheet rubber, stainless steel gasket, and wherein sheet rubber and stainless steel gasket closely bond, and stainless steel gasket is greater than sheet rubber.
In technique scheme, sheet rubber and stainless steel sheets are circle and center drilling, hold bolt and pass.
In technique scheme, the center hole of sheet rubber is littler than the center hole of stainless steel gasket, and sheet rubber and bolt are interference fit.
Compared with prior art, the utlity model has following beneficial effect: in installation process, when the power that tights a bolt reaches certain degree, can make whole pad produce distortion; Thereby reach the effect of sealing, because stainless steel gasket is greater than sheet rubber, under pressure; Stainless steel gasket can cover sheet rubber fully; Increase sealing effect, because the sheet rubber part is an interference fit with bolt, all reach designing requirement again through leak test to liquid (water), gas (nitrogen).The gasket seal of the utility model can strengthen technique effects such as the tightness, vibrationproof, corrosion protection of sealing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cross section view.
In conjunction with the accompanying drawing following reference character of mark above that:
The 1-sheet rubber; The 2-stainless steel gasket.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
The utility model such as Fig. 1, shown in Figure 2, this stainless steel gasket seal is by sheet rubber 1 and stainless steel gasket 2 two-part bonding composition.
Further as shown in Figure 2; Sheet rubber 1 is a ring structure with stainless steel gasket 2; The intermediate hole of sheet rubber 1 and stainless steel gasket 2 is concentric when bonding, but the diameter of sheet rubber 1 intermediate hole less than the diameter of stainless steel gasket 2 intermediate holes, and with assembling bolt be interference fit.The external diameter of sheet rubber 1 is also less than the diameter of stainless steel gasket 2.In installation process, when the power that tights a bolt reaches certain degree, can make whole pad produce distortion, thereby reach the effect of sealing.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
