Abstract

PURPOSE: To increase durability of a sheet packing by forming a nearly L-figure shaped groove on the section and insertion-fitting a sheet packing which has the two-sided contact seal part on the contact side with a spherical inner valve and has the flat annular part formed on the back side.
CONSTITUTION: When a fluid intercepting pressure is applied to a spherical inner valve 3, the spherical inner valve 3 is pushed to the downstream side, and the flowing-path side of a sheet packing 1 bends to the maximum, and the flat annular part 6 is pushed to the valve body 2. Further, a load is received by this surface and the load receiving surface serving both as sealing surface 8, and thus deformation of the seat packing 1 can be prevented. As a deflection over a limit is not applied to the flowing-path side part of the sheet packing 1, initial elasticity can be maintained for a long period, and durability of sheet packing can be improved.
