Claims

[Claims for Utility Model Registration] (1) In a body split-type ball valve formed by joining a main body and a sub-body that are aligned on the axis, the mouth edge of the main body is arranged so that the inner circumferential surface faces toward the inner part. It is formed by a small-diameter annular part that is tapered to reduce its diameter, and a large-diameter annular part that has a slightly larger diameter and protrudes from the small-diameter annular part. It has a tapered shape,
and a small diameter fitting part whose tip can be fitted into the small diameter annular part;
The above-mentioned large-diameter annular part is enlarged by 1,000 yen, and a medium-diameter fitting part where the small-diameter annular part and the end faces can face each other with a slight distance from each other, and a large-diameter opposing part where the large-diameter annular part and the end faces can face each other with a little distance from each other. A sealing device for a split body part in a split body ball valve, characterized in that the small diameter annular part and the medium diameter fitting part have a gasket interposed between the end faces thereof. -(2) The device according to claim (1) of the utility model registration, in which a large number of grooves facing in the same direction as the axis are cut into the inner circumferential surface of the small-diameter fitting portion. (3) The device according to claim (1), which is a registered utility model, in which a concave groove facing in the circumferential direction is cut in the inner circumferential surface of the small-diameter fitting portion.
