Abstract

The experiment apparatus for isothermal container discharge method in measurement and control fields includes gas source, decompression valve, stop valve, temperature sensor, isothermal container, pressure sensor, data recorder, barometer, upstream rectifier tube, upstream rectifier tube joint, downstream rectifier tube joint, and downstream rectifier tube connected together, except the barometer set in atmosphere directly. The element to be measured has its intake connected via the upstream rectifier tube joint with the upstream rectifier tube and its exhaust connected via the downstream rectifier tube joint with the downstream rectifier tube. The experiment apparatus of the present invention has simple structure, short measurement time, low air consumption and other advantages.

Description

technical field [0001] The invention relates to a measuring device for measuring the flow characteristics of pneumatic components, in particular to an experimental device for isothermal container release method. Used in the field of measurement and control. Background technique [0002] The current international standardization draft ISO6358 for measuring the flow characteristics of actual pneumatic components has the disadvantages of complicated testing equipment, long measurement time, and large power consumption. For this reason, a new test method must be adopted. At present, the replacement test methods include the fixed container filling method and the release method. The isothermal container is an important tool to ensure the accuracy of the above-mentioned replacement test methods. Therefore, the development of the isothermal container is very necessary. The process of filling and deflating the fixed volume is very short, only a few seconds, and its energy consumptio...
