Examples
(1) Measuring the closing height and closing angle of the breather valve 3: when the breather valve 3 is fully opened, recording the initial angle and the height respectively through the angle sensor 26 and the displacement sensor 29; the movable part of the angle sensor 26 is driven to rotate together by rotating the breather valve 3, and when the breather valve 3 is completely closed, the numerical values of the closing height and the closing angle of the breather valve 3 are obtained by comparing the initial values, so that the measurement is completed;
