1. What is a gas busbar

In order to improve work efficiency and safe production, the gas bus bar combines the gas sources of a single gas supply at a single gas point, and combines multiple gas-containing containers (high-pressure steel cylinders, low-temperature dewars, etc.) to achieve centralized gas supply installation

2. Advantages of using the busbar

  • The use of bus bars can save the number of cylinder changes, reduce the labor intensity of workers and save labor costs.

  • Centralized management of high-pressure gas can reduce the existence of potential safety hazards.

  • It can save site space and make better use of site space.

  • Facilitate gas management.

The gas busbar is suitable for enterprises with large gas consumption. Its principle is to input bottled gas into the busbar main pipeline through clamps and hoses, and then decompress and adjust the gas to be transported to the site where it is used. It is widely used in hospitals. , Chemical industry, welding, electronics and scientific research units.

3. Basic performance of gas busbar

Refers to the bottled high-pressure gas, which is decompressed to a certain operating pressure through this equipment, which is a kind of equipment for centralized gas supply. The busbar is composed of two main confluence pipes on the left and right. There are four high pressure valves in the middle, which control the two sets of manifold pipes on the left and right. Each group has a considerable number of sub-valves. The hoses and fixtures are connected to the gas cylinders. A high pressure meter is installed in the middle. , Used to detect the pressure in the manifold. There are two sets of pressure reducers above the high pressure valve to control and adjust the use pressure and flow. There are two low pressure valves above the pressure reducer to control the low pressure gas when the two rows of confluence switch are switched. , Confluence low-pressure main pipeline is equipped with a low-pressure main valve to control the gas in the low-pressure pipeline.

It is a device for centralized inflation or gas supply. It connects multiple cylinders of gas to the confluence main pipe through valves and conduits, so that these cylinders can be inflated at the same time; or after being decompressed and stabilized, they are transported to the place of use by pipelines. Equipment to ensure that the gas source pressure of the gas appliance is stable and adjustable, and to achieve the purpose of uninterrupted gas supply.

The applicable media include helium, oxygen, nitrogen, air and other gases, which are mainly used in large gas-consuming units such as industrial and mining enterprises, medical institutions, and scientific research institutions. This product has reasonable structure, advanced technology and simple operation. It is an important device to ensure safety and realize civilized production.

This product is distinguished according to the number of gas cylinders and configuration, and has a variety of structural forms, including 1×5 bottle group, 2×5 bottle group, 3×5 bottle group, 5×5 bottle group, 10×5 bottle group, etc. Option, special configuration can also be made according to user needs and environmental requirements. The gas pressure of this product is adapted to the nominal pressure of the configured gas cylinder.

Including oxygen bus, nitrogen bus, air bus, argon bus, hydrogen bus, helium bus, carbon dioxide bus, carbon dioxide electric heating bus, propane bus, propylene bus, acetylene bus, neon Various gas busbars such as busbars, nitrous oxide busbars, and Dewar tank busbars.

4. Safe use and maintenance of gas busbars

  • Opening: The stop valve in front of the pressure reducer should be opened slowly to prevent sudden opening, which may cause the pressure reducer to fail due to high pressure shock. Point out the pressure by the pressure gauge, then turn the pressure reducer to adjust the screw clockwise, the low pressure gauge points out the required output pressure, open the low pressure valve, and supply air to the working point.

  • To stop the air supply, all you need to do is to loosen the pressure reducer adjusting screw. After the low pressure gauge is zero, close the shut-off valve to prevent the pressure reducer from being pressured for a long time.

  • Both the high pressure chamber and the low pressure chamber of the pressure reducer are equipped with safety valves. When the pressure exceeds the allowable value, the exhaust is automatically opened, and the pressure drops to the allowable value to close automatically. Do not move the safety valve at ordinary times.

  • When installing, pay attention to the cleaning of the connecting part to prevent debris from entering the pressure reducer.

  • If air leakage is found in the connection part, it is generally due to insufficient screw tightening force or damage to the gasket. The sealing gasket should be tightened or replaced.

  • It is found that the pressure reducer is damaged or leaking, or the pressure of the low pressure gauge is continuously rising, and the pressure gauge does not return to the zero position, etc., and it should be repaired in time.

  • The busbar should use one medium according to the regulations, and should not be mixed to avoid danger.

  • The oxygen bus bar is strictly prohibited from contacting grease to avoid burning and fire.

  • Do not install the gas bus bar in a place with corrosive media.

  • The gas bus bar must not be inflated to the gas cylinder in the reverse direction.
