Sealing device with adjustable sealing performance

Abstract

The invention discloses a sealing device with adjustable sealing performance. The sealing device comprises a first annular frame, a second annular frame, a third annular frame and a plurality of shells which are open at one ends and are used for containing colloid, the first annular frame is located on the outer circumference of the second annular frame, the second annular frame is located on theouter circumference of the third annular frame, a plurality of first magnets are arranged on one side of the inner circumference of the first annular frame, the shells are evenly arranged on the second annular frame, the openings of the shells are provided with second magnets, the bottoms of the shells are provided with nozzles, the second magnets repel the first magnets, a connecting rod is arranged between the first annular frame and the third annular frame, the surface of the side, opposite to the first magnets, of the third annular frame is provided with holes, the inner circumference of the other side of the third annular frame is provided with a plurality of rollers, and the outer circumference of the first annular frame is provided with a driving device for driving the first annularframe to rotate. The device can effectively extrude gas and leaking liquid from the colloid while the colloid is sprayed, and the poor sealing is avoided.

Description

technical field [0001] The invention relates to sealing equipment, in particular to a sealing device with adjustable sealing performance. Background technique [0002] When the pressure in the pipeline is too high between the flanges on the pipeline, it is very easy to cause the shaking between the flanges and the reduction of the sealing effect, which will cause the fluid in the pipeline to leak, while the existing sealing When the device seals between the flanges, when the colloid is used for sealing, it is often because the leaked liquid is mixed with the gas and then mixed with the colloid, resulting in a gap between the colloid and the flange, resulting in The problem of poor sealing effect. Contents of the invention [0003] In view of the above prior art, the technical problem to be solved by the present invention is to provide a kind of sealing effect that can prevent the colloid from being filled with gas and liquid when sealing, and the reliability of the device...
