材。[Claims for Utility Model Registration] (1) Connection sleeves are connected to the upstream opening and the downstream opening of the valve body through packing members, and the joint end faces of these connecting sleeves or the upstream opening and downstream In a valve in which an annular recess is formed on either of the joint end surfaces of the side openings, the packing member is a flat annular body having an opening in the center having approximately the same diameter as the upstream opening and the downstream opening. An annular protrusion that fits into the annular recess is formed on one end face of the flat annular body, and an annular bulge is formed on the other end face opposite to the annular protrusion. packing parts. (2) The packing member according to claim 1, wherein both end surfaces on the inner diameter side of the annular protrusion and the annular bulge are formed into tapered surfaces that gradually widen as they go inward. (3) The packing member according to claim 1 or 2, wherein a plurality of annular ribs are formed on both end faces on the inner diameter side of the annular protrusion and the annular bulge. (4) The packing member according to any one of claims 1 to 3, wherein a plurality of support protrusions are formed on the outer peripheral edge of the packing member.
