Diaphragm capsule power element counter-force correction device

The utility model provides a diaphragm capsule power element counter-force correction device. The device is provided with a support. The support is provided with a correction groove for placing a diaphragm capsule power element and a supporting rod for supporting a downward-pressing mechanism. The supporting rod is provided with a limiting hole. The downward-pressing mechanism is arranged above the correction groove and composed of a downward-pressing handle, a connecting rod and a punch. The punch moves vertically along with rotating of the downward-pressing hand along the center line of the correction groove. According to the diaphragm capsule power element counter-force correction device, by operating the downward-pressing mechanism, a diaphragm capsule bearing overly large counter force is readjusted in the correction groove, the punch of the downward-pressing mechanism is pressed downwards to the ultimate position to be fixed, and accuracy of correction is guaranteed; meanwhile, through a moving mechanism, the distance between the downward-pressing mechanism and the correction groove can be adjusted, and the counter force of the corrected diaphragm capsule can be changed at will.
