Preferably, a plurality of reinforcing columns are uniformly distributed on the inner side of the sealing element body in an annular manner, the central axes of the reinforcing columns are parallel to the central axis of the sealing element body, annular grooves for mounting the reinforcing columns are formed in the upper ends of the plurality of reinforcing columns, and sealing strips are matched in the annular grooves in a nested manner
Preferably, the width of the sealing gasket in the radial direction is the same as the width of the cavity in the radial direction, and the thickness is the same as the height of the cavity.
Preferably, the height of the second arc-shaped protrusion is 1/4-1/6 of the height of the cavity.
Compared with the prior art, the utility model has the advantages that:
(1) because can produce the voltage-sharing electric field under the electric field effect, consequently composite rubber sealing ring's dynamic service environment need consider the influence that the electric field effect produced to it, then higher to composite rubber sealing ring's requirement this moment, the utility model discloses in, sealed the pad has been add on the sealing member body, sealed pad and cavity cooperation, and because the terminal surface is uneven structure under the cavity, consequently sealed pad in the pressurized in-process up end also has slight unevenness condition, and there are a plurality of contact points in the contact surface of gully form to form the multichannel sealed, sealed effect is better.
(2) The setting of reinforcement post can guarantee that the sealing member body is difficult for appearing skew axial deformation by a wide margin, and the sealing member body also can play good sealed effect under the pressurized state when guaranteeing structural connection.
Drawings
The invention will be further described with reference to the following drawings and examples:
FIG. 1 is a cross-sectional view of a composite rubber sealing member according to the present invention applied under the action of an electric field;
fig. 2 is a partial enlarged sectional view of the composite rubber sealing member applied under the action of the electric field.
Wherein: 1. the sealing element comprises a sealing element body, 2, a through hole, 3, a first arc-shaped protrusion, 4, a cavity, 5, a second arc-shaped protrusion, 6, a sealing gasket, 7, a reinforcing column, 8 and a sealing strip.
Detailed Description
The following detailed description is made in conjunction with specific embodiments of the present invention:
as shown in fig. 1 and 2, the composite rubber sealing element applied to the action of an electric field comprises a sealing element body 1, wherein the sealing element body 1 is annular, the middle part of the sealing element body is provided with a through hole 2, the upper end surface of the sealing element body is provided with a cavity 4 which is annularly arranged, and a sealing gasket 6 is nested and matched in the cavity 4; the upper end and the lower end of the inner wall of the through hole 2 are in symmetrical horn-shaped structures, and the middle section of the inner wall is provided with a plurality of first arc-shaped bulges 3 which are uniformly distributed in a ring shape; the lower end face of the cavity 4 is provided with a plurality of second arc-shaped protrusions 5 which are coaxially arranged in an annular shape, and the height of each second arc-shaped protrusion 5 is 1/4-1/6 of the height of the cavity 4.
