AI Technical Summary

Technical Problem

During the calibration of a gas flow meter, if the staff pushes the measuring rod during installation, it may cause the measuring rod to collide with the inner wall of the device, resulting in measurement errors and affecting the calibration quality.

Method used

The design employs a combination of expansion mechanism, rotation mechanism, sliding component, positioning component, and swing component. Through the synergistic effect of spring and arc plate, the measuring rod achieves stable positioning and parallel movement, reducing collisions and deviations.

Benefits of technology

It effectively reduces the error of the measuring rod during measurement, improves the quality and efficiency of calibration, and ensures the stable installation of the measuring rod and the accuracy of the data.

Abstract

The invention relates to the technical field of flowmeter calibration, and discloses a tandem type gas flowmeter calibration device which comprises a main body, and a plurality of connectors are fixedly connected to the top of the main body. Thrust is applied to the spring at the top of the sliding plate in the sliding process of the sliding plate, potential energy is accumulated while the spring shrinks after the spring is subjected to the thrust, then the sliding plate cannot continue to move at the moment after the spring completely shrinks, the measuring rod stops moving after the sliding plate stops moving, and therefore positioning of the measuring rod is completed. The situation that when a worker pushes the measuring rod to move towards the interior of the main body to meter subsequent gas, the worker excessively pushes the measuring rod in the installation process, so that a detection block at the bottom of the measuring rod collides with the inner wall of the main body is reduced; therefore, errors of the measuring rod during metering can be reduced, and the calibration quality can be improved at the same time.
