Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] Such as figure 1 Shown, a kind of helium recovery device that is used for leak detection of high-pressure gas cylinder of the present invention is made of high-pressure gas cylinder (1), temperature measuring sensor (2,7), vacuum gauge (3,8), pressure relief controller (4), high-pressure cut-off valves (5, 9, 16, 19), gas storage container (6), fine-tuning valve (10), cold cathode ionization vacuum gauge (11), mass spectrometry chamber (12), mass spectrometer ( 13), a high vacuum pump (14), a low vacuum pump (15, 18), a low vacuum valve (17), a high-purity nitrogen source (20) and pipelines. Schematic see figure 1 , the high-pressure gas cylinder (1) is used as a recovery source, and it is a product to be inspected with a certain pressure. The working pressure is generally (10-60) MPa; The temperature of the container surface; the vacuum gauge (3...

Abstract

The invention discloses a helium recovery device and a recovery method for leak detection of high-pressure gas cylinders, including a gas storage container, a temperature and pressure monitoring unit, a measuring instrument, a replacement system, a pressure relief controller and an evacuation unit; the gas storage container is used for Store the helium recovered from the detected high-pressure gas cylinder; the temperature and pressure monitoring unit is used to monitor the temperature and pressure of the high-pressure gas cylinder and the gas storage container during the recovery process, and the measuring instrument is used to measure the helium in the recovered gas storage container Helium concentration; the replacement system is used to replace the air in the gas storage container before recovery to ensure the purity of the recovered helium; the pressure relief controller is used to adjust the pressure release rate of the high-pressure gas cylinder to the gas storage container, and the evacuation unit is used to Vacuumize the gas storage container; the invention can recover the helium after the leak detection of the high-pressure gas cylinder, and at the same time ensure that the recovered helium has a certain purity, which can meet the requirements for the next leak detection.

Description

technical field [0001] The invention belongs to the technical field of helium recovery devices, and in particular relates to a helium recovery device and a recovery method for leak detection of high-pressure gas cylinders. Background technique [0002] In the technical field of satellite propellant leakage detection, it is necessary to solve technical problems such as low detection sensitivity, weak resolution and high false alarm rate through technical research and detection practice. The shape of the high-pressure gas cylinders used in the leak detection process includes spherical, cylindrical and ring-shaped, the volume ranges from a minimum of 2L to a maximum of 670L, and the burst pressure is as high as 150MPa. For the leak rate detection of high-pressure gas cylinder products, the annual helium consumption is 200 bottles For the above, it is urgent to develop a helium recovery device for leak detection of high-pressure gas cylinders, which can greatly reduce the detect...
