Claims

[Scope of utility model registration request]

A spherical valve in which a spherical valve element is sealed between a pair of valve seats in a valve body having an inflow and outflow passage for fluid, and the fluid passage is opened and closed by rotating the spherical valve element. , the above-mentioned pair of valve seats are respectively attached to a pair of valve seat holders disposed movably in the axial direction of the fluid inflow and outflow passage within the valve body, and the back surface of each valve seat holder is made a slope, and each A pair of "wedge" shaped members movable in a direction perpendicular to the fluid inflow/outflow passage are disposed between the back surface of the valve seat holder and the valve body symmetrically with respect to the center of the spherical valve; Further, a pressing member is provided to press each "wedge" shaped member in a direction perpendicular to the fluid inflow/outflow passage, so that the "wedge" shaped member is
A spherical valve characterized in that the surface pressure between each valve seat and the spherical valve element can be adjusted by pressing a wedge-shaped member.
