Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

A novel gasket with good sealing performance is disclosed, as shown in fig. 2-7, and comprises a middle plate 1 and two side plates 2, wherein a first central hole 11 is formed in the center of the middle plate 1, a second central hole 21 is formed in the center of each side plate 2, the first central hole 11 and the second central hole 21 facilitate the passage of a pipeline, sliding cavities 12 are formed in two sides of the middle plate 1, the two side plates 2 are respectively arranged in the sliding cavities 12 in two sides of the middle plate 1 in a sliding mode, namely the side plates 2 in two sides can slide, a plurality of elastic sheets 13 are arranged at the bottom of each sliding cavity 12, and the inner diameter of part of the side wall of the second central hole 21 is gradually reduced to form a slope surface section 22;

when the side panel 2 is moved towards the centre panel 1, the ramp section 22 presses against the resilient tab 13.

The sliding cavity 12 is circular ring shape, and shell fragment 13 has a plurality of, and a plurality of shell fragment 13 evenly sets up in sliding cavity 12, and a plurality of shell fragments 13 encircle around first centre bore 11, and when the pipeline inserted first centre bore 11 promptly, a plurality of shell fragments 13 encircle around the pipeline, and when shell fragment 13 warp, shell fragment 13 can tightly laminate around the pipeline.

The part with the same inner diameter of the second central hole 21 is defined as a straight surface section, the inner diameter of the straight surface section is the same as the inner diameter of the first central hole 11, namely when the pipeline is inserted into the first central hole 11 and the second central hole 21, the inner walls of the straight surface section and the first central hole 11 can be attached to the outer wall of the pipeline, and the straight surface section and the inner wall of the first central hole 11 can play a role in sealing.
