Description

Technical Field

[0002] A gas cylinder refers to a movable pressure vessel with a bottle-shaped main structure, generally filled with gases (which can be compressed gases, liquefied gases, dissolved and adsorbed gases, etc.). Gas cylinders are widely used and are almost indispensable in both the production field and the life field. Among them, according to national standards, seamless gas cylinders need to be hydrostatically tested regularly (3 - 5 years) to determine whether they can be refilled.

[0003] In the current prior art, Chinese invention patent application CN202221307379.7 discloses a moisture removal device for gas cylinders. By setting a limiting unit, the gas cylinder can maintain an inverted state after rotating with the clamping unit, and the moisture inside the gas cylinder can flow out quickly and effectively under the action of gravity; by setting a heating unit, it is ensured that the moisture inside the gas cylinder can be removed completely. However, the outflowing moisture cannot be recycled and reused in time, resulting in waste of water resources. Moreover, for some special gas cylinders, the water source flowing out after hydrostatic testing will carry out the residual impurities inside the gas cylinder. If not cleaned in time, it is easy to cause the situation of dirty testing sites.
