Abstract
Provided is a symmetry degree measuring method of ball valve two end faces. An A face and a B face are machined on two end faces of a ball valve (7) . A measuring device comprises a measuring platform (1), a compressing bolt (2), a V-shaped block (3), a measuring meter (4), cushion blocks (5) with various heights and a meter seat (6). The symmetry degree measuring method of ball valve two end faces comprises the following steps: fixing measuring meter with a journey equaling to or larger than R minusing half H on a fixing meter seat through the compressing bolt, placing the ball valve of 2R inside the V-shaped block and enabling the A face and the B face of the ball valve to be in a mutual parallel mode with a symmetrical center line through the cushion blocks with various heights, the parallel mode reading out a basic value H 0 through a maximum retraction quantity. Measured and calculated symmetrical values of the A face and the B face being respectively delta HA equalling to H0 minus HA and delta HB equalling to H0 minus HB. If delta HA equals to delta HB, the A face and the B face are symmetrical corresponding to the ball valve center line. If delta HA is larger or smaller than delta HB, the A face and the B face are asymmetrical. The symmetry degree measuring method of ball valve two end faces is simple, convenient, fast and accurate.
