Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas cylinder testing, in particular to a gas cylinder air tightness testing device. Background Art
[0002] In industrial and chemical production activities, some gases are often required. For the convenience of transportation and use, high-pressure gas cylinders came into being. High-pressure gas cylinders can hold as much gas as possible in a relatively small volume. The airtightness of gas cylinders is an important production indicator of gas cylinders. After the gas cylinders are produced, they must be tested for airtightness to avoid possible defects in the gas cylinder body that may cause safety accidents. Sealing tests are required to ensure that there is no leakage at the gas cylinder valve position.
[0003] When testing the air tightness of a gas cylinder, the gas cylinder is usually placed in water, and then pressurized gas is passed into the gas cylinder to observe whether bubbles are generated, so as to determine whether the gas cylinder has a leak. Due to the large size of the gas cylinder, it is inconvenient for workers to put the gas cylinder into the testing device, resulting in high labor intensity for the workers. In addition, when the gas cylinder is placed in a container filled with water, small bubbles will be carried on the surface of the gas cylinder. When pressurized gas is passed into the gas cylinder, the bubbles on the surface of the gas cylinder emerge from the water, which may easily lead to misjudgment by the workers. Therefore, a gas tightness testing device for gas cylinders is proposed. Utility Model Content
