The outer ring surface of described upper cover and bottom is equipped with annular projection respectively.
Described upper cover and bottom are connected by screw rod: the screw rod above covered passes the through hole on bottom and uses nut screwing clamping after being set with upper gasket, compression spring.
Described screw rod is covered upper by rivet.
Described upper cover and the outer ring surface of bottom are respectively arranged with several arc grooves one to one.
Groove is provided with inside the through hole of described bottom.
Described seal rubber material is made, when selecting, the medium (such as gas, oils, water etc.) that position uses can be sealed as required and determine to use the seal of different materials (seal that the such as material such as ethylene propylene diene rubber or silicone rubber manufactures).
Described upper cover and seal are that seal is molded directly within the integral structure covered.
Described bottom and seal are the integral structure that seal is molded directly within bottom.
The present invention has following outstanding and useful technique effect compared to existing technology:
1, bottom one middle side part of the present invention is provided with groove, when with upper cover fitted seal, because sealing area is large, can ensure that upper cover and bottom bear larger load, good seal performance after fastening;
The outer ring surface of 2, upper cover of the present invention and bottom is equipped with annular projection respectively, can guarantees that the load of bearing between the present invention and the special-shaped chamber be closed is large, good seal performance;
3, upper cover of the present invention and bottom are located by locating column, avoid its cooperation position to offset from each other, and can guarantee the cooperation position accurate positioning of upper cover and bottom.
4, structure of the present invention is simple, 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.
