Aluminum foil composite film sampling bag for liquefied petroleum gas sampling

Aluminum foil composite film sampling bag for liquefied petroleum gas sampling

Sampling bag usage method and precautions:

The on-off valve is operated by the valve stem. When the valve stem rotates clockwise to the end, it is closed, and when it rotates counterclockwise to the end, it is open

The upper cap of the type switching valve is the switch of the valve. By rotating the upper cap to open the switch, gas is introduced from the side tube of the valve. After closing the switch, the sampling port of the needle on the cap can be injected for sampling;

Replace the gas bag with sample gas or inert gas before use;

The inflation pressure should not exceed 6000pa; visually observe that the airbag is fully inflated; But pressing with fingers is not very tight.

Operating temperature: Other temperatures range from -30 ℃ to+50 ℃;

When storing and using, keep away from open flames and high temperatures; Do not touch hard objects to avoid puncturing the membrane material;

Various interfaces, instruments, equipment, and devices should be connected using corresponding soft rubber hoses for transition;

Sampling can be done with a needle;

Collect or store corrosive gases, it is recommended to choose full plastic switch valve airbags.

Silicone connecting hoses can be used for gas sample collection.

Double connected ball is a simple tool for collecting gas samples

1) The on-off valve is operated by the valve stem. When the valve stem rotates clockwise to the end, it is closed, and when it rotates counterclockwise to the end, it is open; The on-off valve can only be fully opened or fully closed, and cannot adjust the flow rate;

2) Replace the gas bag with sample gas or inert gas before use;

3) The inflation pressure should not exceed 3000pa; visually observe that the airbag is fully inflated, but it is not very tight when pressed with fingers.

4) Operating temperature: -30 ℃ to+50 ℃;

5) When storing and using, keep away from open flames and high temperatures; Do not touch hard objects to avoid puncturing the membrane material;

6) Various interfaces, instruments, equipment, and devices should be connected using corresponding soft rubber hoses for transition;

7) When using the dual opening and closing valve, one in and one out can be used for easy cleaning of the airbag;

8) Collect or store corrosive gases, it is recommended to choose full plastic switch valve airbags.
