Detailed description of the invention
For helping those skilled in the art can understand claimed theme definitely, describe the detailed description of the invention of the present invention below in conjunction with the accompanying drawings in detail.
In order to solve this special construction sealing problem, nor affect on assembling beat simultaneously, devise the special pad of following structure.In the three faying face positions that pad is corresponding, convex tendon form increases glue groove structure, in the case of not weakening convex tendon sealing function, (elastomer is generally gelatin substance to be pre-charged with a kind of elastomer in glue groove, by sulfuration or adhesive form, elastomer can be combined with pad), being used for making up the difference in height that flange face produces, when flange face compression gasket, elastomer is squeezed and can be filled up completely with the leakage channel that difference in height causes.Thus reach the effect fully sealed.
See Fig. 3, the sectional view of the assembling device with sealing function for the present invention relates to.The described assembling device with sealing function includes first split 300 with first surface 301, there is the second split 400 of second surface 401, with pad 100, described first surface 301, second surface 401 are by the faying face 500 between the first split 300 and the second split 400 separately, pad 100 is provided with convex tendon 101, and convex tendon 101 contacts described first surface 301 and second surface 401.Wherein, when the first split 300 and the second split 400 misplace, a surface in faying face 500, described pad 100 and described first surface 301, second surface 401 surrounds cavity 700.Seeing Fig. 4-5, fix elastomer 200 on described convex tendon 101 position, described elastomer 200 contacts the first split 300 and the second split 400 simultaneously.When first, second split 300,400 dislocation, when pad 100 transmits extruding force to first split the 300, second split 400, described elastomer 200 can fill described cavity 700, has thus reached completely enclosed.
Described convex tendon 101 forms ring on the surface of described pad 100, convex tendon 101 is to highlight formation along the direction towards the first split 300 and the second split 400, laterally projecting on the both sides of described ring being provided with a pair branch's groove 102, the two ends of described elastomer 200 are respectively embedded in described branch groove 102.
Described elastomer 200 is gelatin substance, and pad 100 described in its modular ratio is little.The material of described pad 100 is preferably metal or the composite with metal as base material.
Described first split 300 can be vacuum pump seat upper part, described second split 400 can be vacuum pump seat lower part, described first split 300 and the second split 400 split are formed through first surface 301, the opening of second surface 401, hole 104 on pad 100 is corresponding to this opening, and described convex tendon 101 forms ring and around described hole 104.Described convex tendon 101 is formed by described pad 100 is prominent, and described convex tendon 101 side (being equivalent on the inner surface 103 of pad 100) all contacts with described first surface 301, second surface 401.The longer axis parallel of described elastomer 200 is vacuum pump end cap in described faying face 500, securing member 600, by pad 100, described vacuum pump seat upper part, vacuum pump seat lower part is connected vacuum pump end cap respectively with bolt.
The present invention is by increasing a kind of elastomer at special area in metal plate pad technology, and elastomer compression was filled up scheme of the invention that leakage channel reaches to seal later.
Although being illustrated in detail in and described the specific embodiment principle with the explanation present invention of the present invention, it will be appreciated that, the present invention can be with embodied in other without deviating from such principle.
