Problems solved by technology

For a calibration device that can calibrate a variety of vacuum gauges or other vacuum measuring devices, due to its many functions and components, the existing auxiliary facilities for calibration and inspection such as test benches or test cabinets cannot meet the requirements of such calibration devices. Building requirements, building and assembling such calibration devices on the existing auxiliary facilities for calibration and inspection will lead to poor structural stability of the assembled calibration devices, which will easily lead to damage to the detection pipelines for calibration, such as bending or twisting of the pipelines. The pipe wall is broken or the pipe is blocked, which may cause the calibration accuracy to decrease or even make the calibration impossible
Moreover, most of the existing vacuum calibration devices have the problems of single function, narrow calibration range, and low calibration accuracy, which makes the measurement units have to build more calibration devices to meet the actual calibration needs.

Description

technical field [0001] The invention relates to a metering device, in particular to a multifunctional calibration device for vacuum and leak rate. Background technique [0002] Vacuum calibration technology and leak rate detection technology are of great significance in aerospace, surface, microelectronics and other scientific research and production. For scientific research or enterprise production lines, it is necessary to calibrate and test vacuum gauges, vacuum leaks, leak detectors and gas microflow meters. Due to the large number of vacuum parameters, there are many types of calibration devices required. If different calibration devices are prepared for different vacuum parameters, the total cost of building the calibration device will undoubtedly increase, and it will also occupy a large space in the calibration laboratory. . For a calibration device that can calibrate a variety of vacuum gauges or other vacuum measuring devices, due to its many functions and compone...
