Abstract

The invention relates to the technical field of calibrating devices, in particular to a novel calibrating device, comprising a pressure sensor (1), a high-pressure ball valve (2), a high-pressure throttling valve (3), a filter (4), a temperature sensor (5), a flow meter (6), a flange (7) and a steel pipeline (8). All parts in a measurement chamber of the novel calibrating device can not deform due to high pressure, thereby ensuring the measuring accuracy of the novel calibrating device.

Description

Technical field: [0001] The invention relates to the technical field of calibration devices, in particular to a novel calibration device. Background technique: [0002] The scope of calibration devices is very wide, but calibration devices with multiple values ​​for special environments are rare. Aircraft-specific test equipment calibrates many values, including flow, pressure, and temperature parameters of the entire system. However, for the calibration of these parameters, there will be a combination of various calibration devices. The connection between the instruments of the existing combined calibration device is not tight, resulting in a large error value under a certain environment. Invention content: [0003] The purpose of the present invention is to provide a new type of calibration device, in which the components in the measurement chamber will not be deformed due to high pressure, thereby ensuring the measurement accuracy of the calibration device.
