Features:Oxygen pressure reducer YQY-07 is a kind of cylinder pressure reducing device which can reduce the high pressure gas in the cylinder to the practical pressure arbitrarily. It can ensure stable output pressure in case of changes in input pressure and output flow rate, thus ensuring the stability and safety of use. This kind of pressure reducer is widely used in various occasions that need to use oxygen, especially in welding and cutting operations, it can provide stable gas pressure to ensure the smooth progress of work.

Oxygen pressure reducing valve, oxygen regulator, oxygen pressure regulator, etc. are all synonyms for oxygen pressure reducer. Their main function is to reduce the high pressure oxygen to a lower pressure suitable for use, and keep the output pressure stable to meet the different needs of oxygen use, such as medical oxygen intake, industrial welding and so on.

How to use oxygen pressure reducer correctly

The following steps are required to properly use an oxygen pressure reducer:

### Pre-use inspection -

**Check the appearance**: check whether the pressure reducer is damaged, deformed, corroded, etc., to ensure that its appearance is intact. At the same time, check whether the connection parts are tight, there is no loosening, air leakage phenomenon.

- **Check the pressure gauge**: Observe whether the pointer of the pressure gauge is at zero, if not at zero, need to adjust or replace the pressure gauge. And check whether the glass of the pressure gauge is clear and the scale is readable.

- **Check the valves**: Confirm whether the inlet and outlet valves of the pressure reducer can be opened and closed flexibly, and whether the sealing performance of the valves is good.

### Installation and Connection -

**Choose the appropriate connection**: According to the type of interface between the oxygen cylinder and the equipment to be used, choose the appropriate connection, such as threaded connection, ferrule connection and so on. Make sure the connection is firm to prevent gas leakage.

- **Installation of pressure gauge**: Install the pressure gauge correctly on the pressure reducer, and take care to tighten the gauge to avoid loosening during use and affecting the accuracy of the readings.

- **Connecting the oxygen cylinder**: When connecting the oxygen cylinder, close the valve of the oxygen cylinder first, then align the inlet of the pressure reducer with the outlet of the oxygen cylinder and slowly tighten the connecting nut until the connection is tight.

### Adjust the pressure -

**Opening the oxygen cylinder valve**: After connecting the pressure reducer, slowly open the oxygen cylinder valve, at this time, you should stand on the side of the cylinder valve to prevent injury caused by the impact of airflow when the valve is suddenly opened.

- **Adjust the decompression pressure**: After opening the oxygen cylinder valve, observe the high pressure gauge on the pressure reducer, which shows the pressure inside the oxygen cylinder. Then, slowly adjust the regulating knob of the pressure reducer so that the pointer of the low pressure gauge points to the desired working pressure. When adjusting, you should pay attention to the speed of pressure rise to avoid excessive pressure causing safety accidents.

### Precautions in use -

**Maintain ventilation**: When using the oxygen pressure reducer, ensure that the place of use is well ventilated to prevent the accumulation of oxygen from causing fire or explosion and other hazards.

- **Avoid collision**: In the process of use, the pressure reducer should be prevented from being subjected to violent collision or vibration, so as not to affect its performance and accuracy, or even lead to damage.

- ** Pay attention to observe the pressure **: in the process of use, we should often observe the pressure indication of the high pressure gauge and low pressure gauge on the pressure reducer to ensure that the pressure is stable within the prescribed range. If abnormal changes in pressure are found, stop using it immediately and check the reason.

- ** Prohibition of grease contact **: Oxygen and grease contact is easy to cause combustion or even explosion, so in the use of oxygen pressure reducer, should ensure that the surrounding environment is free of grease, the operator's hands and tools, etc. shall not be stained with grease.

### Operation after use

- **Close the valve**: After using, you should close the valve of the oxygen cylinder first, and then slowly loosen the adjusting knob of the pressure reducer until the pointer of the low-pressure gauge returns to zero.

- **Disassembly and storage**: After closing the valve of the oxygen cylinder, wait for a period of time to let the residual gas in the pressure reducer empty, and then disassemble the connection between the pressure reducer and the oxygen cylinder. Be careful to prevent gas leakage when disassembling. Store the pressure reducer properly to avoid being affected by dust, humidity, etc. for the next use.
