Shandong Hengrong Digital Automatic Measurement Recorder for Valve Disc Opening
Developed as supporting equipment for safety valve calibration benches, this recorder adopts high-precision displacement sensing technology. It digitally collects, digitally displays and records the valve disc lift, popping instant and reseating displacement automatically during safety valve calibration. It replaces the traditional manual visual estimation of opening height to eliminate manual reading errors. The objective test data can be stored, meeting the calibration requirements specified in relevant safety valve standards.
Conventional calibration relies on visual observation of valve disc lift, which brings large subjective reading deviation and no raw records, failing to satisfy quality inspection archiving and audit requirements of special equipment inspection organizations. This device captures tiny displacement changes of the valve disc in real time and directly displays opening height on digital screen. It automatically records key data of popping and reseating, and can be seamlessly integrated with safety valve calibration benches. It is widely used for offline safety valve calibration in valve manufacturers, special equipment inspection institutes and enterprise quality inspection laboratories.
