Nanjing Laboratory gas pipeline project

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. Keep gas purity Special cylinders are equipped with flushing valves to remove impurities introduced when replacing cylinders each time to ensure the purity of pipeline terminal gas.

2, uninterrupted gas supply gas path control system can manually or automatically switch between cylinders, to ensure the continuous supply of gas.

3, low pressure warning when the pressure is lower than the alarm limit, the alarm device can automatically start the alarm.

4. The gas pressure stabilization system adopts two stages of decompression (one is regulated by the air supply control system, and the other 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, can make full use of the gas in the cylinder, reduce the residual gas, reduce the cost of gas.

6, easy to operate all cylinders are concentrated in the same location, reduce handling and installation operations, and save time and cost.

7, reduce the rental of gas cylinders the central gas supply system can reduce the number of gas cylinders, so as to save the cost of renting and buying gas cylinders.

8, reduce molecular sieve loss control of gas purity can effectively reduce the number of molecular sieve use (cost savings).

9. Without gas cylinders, the central gas supply system in the laboratory means that there is no gas cylinder equipment in the laboratory, which has the following benefits: -- Improve safety. 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 control valve damage and loss rate. -- Shorten the length of the connecting pipe between the air valve and the instrument, which is more convenient
