The technological scheme that the present invention adopts is:
A kind of special-shaped inner wall sealing spare; Comprise loam cake and bottom; The outer ring surface of loam cake and bottom all has the surface configuration that matches with the internal surface of the special-shaped inner chamber that is sealed; Described loam cake is provided with some screw rods and positioning hole, has the periphery of the loam cake of screw rod one side to be equipped with arc convex, and the outer ring surface of loam cake and arc convex are provided with the flexible seal of one deck; Said bottom be provided with on the through hole that cooperates one by one of the screw rod that covers and with on the locating column that matches of the positioning hole that covers, have the bottom edge of locating column one side to be provided with the circular groove that matches with the arc convex of loam cake; The outer ring surface of bottom reaches with the loam cake inner surface for matching and is provided with the flexible seal of one deck; Loam cake is connected, locatees through locating column through screw rod with bottom; Through hole on screw rod and loam cake and the bottom is tightly connected, and locating column and bottom sulfidization molding are integral structure.
Be equipped with annular projection on the outer ring surface of said loam cake and bottom respectively.
Described loam cake is connected through screw rod with bottom: on the screw rod that covers use nut screwing clamping after passing through hole and suit upper gasket on the bottom, compression spring.
Described screw rod covers last through rivet.
The outer ring surface of described loam cake and bottom is respectively arranged with several arc grooves one to one.
The through hole inboard of said bottom is provided with groove.
Said seal is processed with rubber material; When selecting for use, can seal the seal (the for example seal of material manufacture such as ethylene propylene diene rubber or silicone rubber) that the employed medium in position (such as gas, oils, water etc.) confirms to use different materials as required.
Described loam cake and seal are that seal is molded directly within the integral structure that covers.
Described bottom and seal are that seal is molded directly within the integral structure on the bottom.
The present invention compares existing technology and has following outstanding and beneficial technical effects:
1, bottom one middle side part of the present invention is provided with groove, when with the loam cake fitted seal, because sealing area is big, can guarantee that loam cake and bottom bear bigger load, good seal performance after fastening;
2, be equipped with annular projection respectively on the outer ring surface of loam cake of the present invention and bottom, can guarantee the present invention and the special-shaped chamber that is closed between big, the good seal performance of load of bearing;
3, loam cake of the present invention and bottom avoid its cooperation position to squint each other through the locating column location, can guarantee the cooperation position accurate positioning of loam cake and bottom.
4, the present invention is simple in structure, easy to process, good seal performance.
5, structure of the present invention can change with the difference of various special-shaped chambeies opening inwall, is applicable to the sealing to various types of special-shaped chambeies opening internal surface.
