The application requirements and main structure of cylinder gas. Apr 28, 2018

Normally in the organic chemistry experiments, in use will use gas to as a reactant, such as its oxygen and hydrogen, etc., to a certain extent, also can use gas as shielding gas, such as nitrogen, argon, etc., some gas used as fuel, such as gas, liquefied petroleum gas. All of these gases need to be in special containers. It is generally used to compress the cylinder gas.

The cylinder gas is stored in a cylinder to a certain extent and is effectively stored in the cylinder. It is convenient for transportation and can be used in the general laboratory for very pure gas at any time. Due to the high-pressure compressed gas in the cylinder, safety must be strictly observed when used.

Use of cylinder gas.

1. Install the supporting pressure reducing valve on the cylinder. Check whether the pressure relief valve is closed. The method is to turn the pressure handle counterclockwise until the screw is loose.

2. Open the total valve of the cylinder, when the high pressure gauge shows the total pressure in the bottle.

3. Slowly turn the handle knob clockwise to the low pressure gauge to show the pressure required for the experiment.

4. Close the main valve before closing the valve, and then close the pressure relief valve after the relief valve is exhausted. The cylinder is a kind of pressure vessel, which means that the design pressure is not greater than 1m3 in the 1-300kgfcm2 volume, and can be used to compress compressed air or high pressure liquefied gas.

Cylinder gas is a common pressure vessel in civil, public welfare and industrial and mining enterprises. Cylinders are also called cylinders. The main body of the cylinder is composed of composed steel, alloy steel or high quality carbon steel.

Cylinder gas main structure includes: bottle body, cover, base, bottle mouth, Angle valve and fusible plug, shockproof ring and packing, etc. Cylinder gas is characterized by compressed gas or liquefied gas, and some contents are inflammable and explosive medium, which can be refilled and mobile work.

In general, the cylinder gas will be transported by the dangerous goods vehicle in the process of transportation. The manufacturer will deliver the goods directly and have the qualified escorts, the knowledgeable porters, and light loading and unloading. The summer transport should have shading facilities to avoid exposure.
