Abstract

PURPOSE:To elastically perform close contact of a valve body to a valve seat simultaneously smoothly open and close the valve body, by providing a hollowed part in the periphery of the valve seat. CONSTITUTION:A butterfly valve body 3 is mounted through a valve rod 5 supported to a valve case between flanges of connected two pipings, then a valve seat 7 is formed in a protrusive stripe state internally peripherally of a liner 6 of elastic material mounted between the valve case and the piping. An empty hole hollowed part 15 is provided in the periphery side of this valve seat 7 to absorb deformation of the liner 6, arising from strain of the piping, misalignment of the core, tightening state of a flange bolt, etc., improve closing tightness between the valve body 3 and the valve seat 7 and decrease a leak amount of the seat. Simultaneously, transverse force received from the piping is absorbed by said hollowed part 15 not to become a vertical load, then excessively tight contact of the valve body 3 to the valve seat 7 is prevented to smoothly open and close the valve body 3.
