Abstract

PURPOSE: To improve valve seal between a seat set to the valve box and another seat set to the valve body, by composing the former adjustable for its position in terms of the distance from the latter and also composing the latter adjustable for its radial position at the time of assembly.
CONSTITUTION: #2 seat 4, spherical in shape, is set in a valve box equipped with a junction 2 for a fluid conduit 1, while #1 seat 7, elastic and flexible for pressure contact with #2 seat 4 when the valve is closed, is set on the external side of a valve body 5. #2 seat 4 is fixed with a screw 13 to the junction side 3a, the position being adjuatable in terms of the distance from #1 seat 7. #2 seat's surface of contact F with #1 seat 7 is spherical for matching the surface of a virtual ball, with a crossing point of #1 seat 7 and axial center P of the valve body 5 as its center, to improve the seal between both seats 4, 7.
