Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an oxygen cylinder valve airtightness leak detection clamp that is easy to install and remove. Background Technology

[0002] The existing QF-2 oxygen cylinder valves, widely used on oxygen cylinders, typically employ a leak-testing fixture with a horizontally mounted air pipe on a workbench. One end of the air pipe has an inlet connector that connects to the air inlet pipe of the test bench. At least one valve connector with an internal tapered thread is mounted on the air pipe and connects to the inner cavity of the air pipe. A water tank is also located on the workbench, with a water tank lifting cylinder at the bottom. During operation, each oxygen cylinder valve is individually tightened onto the valve connector using an adjustable wrench or a straight-arm wrench. Then, the high-pressure air source is turned on, and the water tank lifting cylinder button is activated, raising the water tank until it submerges the oxygen cylinder valve for the leak test.

[0003] The existing oxygen cylinder valve leak detection fixture, although simple in structure, requires each oxygen cylinder valve to be manually screwed onto the valve connector on the gas pipe for leak detection testing. This results in high labor intensity, low production efficiency, and easy fatigue for employees. Utility Model Content

Next, the button for the baffle 2 lifting cylinder 8 is activated to raise the baffle 2 to its correct position. Then, the high-pressure gas button is activated. At this point, high-pressure gas flows into the oxygen cylinder through the air inlet connector 10 on the positioning plate 3, passes through the air inlet channel 301, and enters the inner cavity of the cylinder valve. Then, the button for the water tank cylinder 8 is activated to raise the water tank to the support plate 501 on the support plate 5, allowing for oxygen leak testing. After the oxygen cylinder valve leak test is completed, the high-pressure gas is completely released. Then, the water tank cylinder 8 is activated to lower the water tank to its correct position. Finally, the cylinder 8 is activated to lower the baffle 2 to its correct position. At this point, each oxygen cylinder valve can be quickly and safely removed.
