Laboratory instrument gas pipeline engineering

In the installation and construction of laboratory gas pipeline engineering, centralized gas supply is often used to transport high purity gas, which has the following advantages:

1, maintain gas purity

Special cylinders are equipped with flushing valves to remove the impurities introduced each time the cylinder is replaced to ensure the purity of the pipeline terminal gas.

2, uninterrupted gas supply

The gas path control system can switch between cylinders manually or automatically to ensure a continuous supply of gas.

3, low pressure warning

When the air pressure is lower than the alarm limit, the alarm device can automatically start the alarm.

4, the gas pressure is stable

The system adopts two levels of decompression (one level is regulated by the air supply control system, the second level is regulated by the control valve of the use point) to supply air, which can obtain very stable pressure.

5, high efficiency

Through the gas supply control system, the gas in the cylinder can be fully used to reduce the residual gas and reduce the cost of gas.

6, easy to operate

All cylinders are located in one location, reducing handling and installation, saving time and cost.

7. Reduce the rent of gas cylinders

The use of a central gas supply system can reduce the number of cylinders required, thereby saving on cylinder rental and purchase costs.

8, reduce molecular sieve loss

Controlling the gas purity can effectively reduce the amount of molecular sieve used (cost saving).

9. No gas cylinders in the laboratory

The use of a central air supply system means that there is no cylinder equipment in the laboratory, which has the following benefits:

-- Improve security. Cylinders may fall to the ground resulting in damage or injury.

-- Improve the sense of security. Gas cylinders may cause dangerous situations such as gas leakage and fire.

-- Save space. Removal of gas cylinders from the laboratory freed up more laboratory space.

10. Other benefits

-- Reduce the damage and loss rate of control valve.

-- Shorten the length of the connecting pipe between the air valve and the instrument, which is more convenient
