Embodiment
For helping those skilled in the art can understand definitely the claimed theme of the present invention, describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
In order to solve this special construction sealing problem, do not affect assembling beat simultaneously yet, design the special pad of following structure.In three junction plane positions corresponding to pad, convex tendon form increases glue groove structure, do not weakening in convex tendon seal action situation, (elastomer is generally gelatin substance in glue groove, to be pre-charged with a kind of elastomer, can elastomer be combined with pad by sulfuration or adhesive form), be used for making up the height difference that flanged surface produces, in the time of flanged surface compression gasket, elastomer is squeezed can the poor leakage causing of complete packed height.Thereby reach hermetic effect.
Referring to Fig. 3, it is the sectional view of the assembling device with seal action that the present invention relates to.The described assembling device with seal action comprises 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 junction plane 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, in the time that the first split 300 and the second split 400 misplace, a surface in junction plane 500, described pad 100 and described first surface 301, second surface 401 surrounds cavity 700.Referring to Fig. 4-5, on described convex tendon 101 positions, fix elastomer 200, described elastomer 200 contacts the first split 300 and the second split 400 simultaneously.In the time of first, second split 300,400 dislocation, in the time that pad 100 transmits extruding force to the first split 300, the second split 400, described elastomer 200 can be filled described cavity 700, has so just reached sealing completely.
Described convex tendon 101 forms ring on the surface of described pad 100, convex tendon 101 is to form along the direction towards the first split 300 and the second split 400 is outstanding, the laterally projecting a pair of branch groove 102 that is provided with on the both sides of described ring, the two ends of described elastomer 200 are respectively embedded in described branch groove 102.
Described elastomer 200 is gelatin substance, and pad 100 is little described in its modular ratio.The material of described pad 100 is preferably metal or the composite material take metal as base material.
Described the first split 300 can be that vacuum pump seat top is divided, described the second split 400 can be that vacuum pump seat bottom is divided, described the first split 300 and the second split 400 amalgamations form the opening through first surface 301, 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 by outstanding formation of described pad 100, and described convex tendon 101 1 sides (being equivalent on the internal surface 103 of pad 100) all contact with described first surface 301, second surface 401.The major axis of described elastomer 200 is parallel to described junction plane 500, and fastening piece 600 is vacuum pump end cap, with bolt by pad 100 by described vacuum pump seat top divide, vacuum pump seat bottom connects respectively vacuum pump end cap.
The present invention is by increasing a kind of elastomer at special area metal plate pad is technical, elastomer compression is filled up afterwards to leakage and reached the scheme of the invention of sealing.
Although at length illustrate and described specific embodiments of the invention so that principle of the present invention to be described, it should be understood that the present invention can embodied in other and do not depart from such principle.
