Abstract
A radiuses measuring tool for valve spools of eccentric half-ball valves comprises a base, calipers, two support components and a fixing ring. The calipers are used for measuring the radius of a valve spool of an eccentric half-ball valve, the two support components are used for mounting the valve spool of the eccentric half-ball valve, the fixing ring is used for determining the spherical center of the valve spool of the eccentric half-ball valve, and is mounted in the center of the top surface of the base, and the two support components are mounted on the top surface of the base, and are symmetrically arranged around the fixing ring. After the valve spool of the eccentric half-ball valve is mounted on the support components, the spherical center of the valve spool is determined by the fixing ring, a measuring claw of the calipers is fixed into the fixing ring, and another measuring claw of the calipers is externally connected onto the valve spool, so that the radius of the valve spool of the eccentric half-ball valve can be measured. Since measuring of the vertical distance from a center point of a connecting line between shaft holes on two sides of the valve spool of the eccentric half-ball valve to the top surface of the valve spool of the eccentric half-ball valve is equivalent to measuring the spherical radius of the spool of the eccentric half-ball valve, the radius measuring tool brings convenience for measuring the radiuses of the valve spools of the eccentric half-ball valves, and is high in accuracy.
