What do you need for oxygen pipes?

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Air traps can be used when oxygen piping needs to be drained.

The high-pressure chamber of the oxygen pressure reducing valve is connected to the cylinder, and the low-pressure chamber is the gas outlet and leads to the use system. The pressure gauge indicates the pressure of the gas stored in the cylinder. The outlet pressure of the low pressure gauge can be controlled by an adjusting screw.

1. When using, first open the main switch of the cylinder, and then turn the low-pressure gauge pressure adjustment screw clockwise to compress the main spring and drive the film, spring cushion and ejector rod to open the valve. In this way, the imported high-pressure gas enters the low-pressure chamber after throttling and decompression from the high-pressure chamber, and leads to the working system through the outlet.

2. The pressure reducing valves are equipped with safety valves. It is a device that protects the pressure reducing valve and makes it safe to use, and it is also a signal device for the failure of the pressure reducing valve. If, due to damage to the valve pad, valve or other reasons, the outlet pressure rises on its own and exceeds a certain permissible value, the safety valve automatically opens and vents.

3. Rotate the adjusting screw to change the height of the valve opening, so as to adjust the flow of high-pressure gas and reach the required pressure value.

4. Precautions for the installation and use of oxygen pressure reducing valves:

1) According to the different requirements of use, there are many specifications of oxygen pressure reducing valves. The maximum inlet pressure is mostly the lowest inlet pressure is not less than a multiple of the outlet pressure. There are many specifications of outlet pressure, generally, the highest outlet pressure is.

2) When installing the pressure reducing valve, it should be determined whether its connection specifications are consistent with the coupling of the cylinder and the system used. The pressure reducing valve and the cylinder are connected by a hemispherical surface, and the two are completely consistent by tightening the nut. Therefore, the two hemispheres should be kept smooth and clean when used to ensure a good airtight effect.

Dust can be blown away with high-pressure gas before installation. If necessary, PTFE and other materials can also be used as gaskets.

3) The oxygen pressure reducing valve should not be in contact with grease to avoid fire accidents.

4) When the work is stopped, the residual gas in the pressure reducing valve should be discharged, and then the adjusting screw should be loosened to avoid the long-term compression deformation of the elastic element.

5) The pressure reducing valve should avoid impact vibration and should not be in contact with corrosive substances.

5. Attention to other gas pressure reducing valves:

Some gases, such as permanent gases such as nitrogen, air, argon, etc., can be treated with oxygen pressure reducing valves. However, there are also some gases, such as corrosive gases such as ammonia, that require special pressure reducing valves. The common pressure reducing valves on the market are nitrogen, air, hydrogen, ammonia, acetylene, propane, water vapor, etc.

The usage and precautions of these pressure reducing valves are basically the same as those of oxygen pressure reducing valves. However, it should also be noted that special pressure reducing valves are generally not used for other gases.

In order to prevent misuse, some special pressure reducing valves have special connections between the cylinder and the cylinder. For example, hydrogen and propane both use a left thread, also known as a reverse thread, and special care should be taken when installing.

Oxygen valves often use oxygen, nitrogen, hydrogen, argon and other gases in physical and chemical experiments. These gases are generally stored in special high-pressure gas cylinders.
