Oxygen valve works and methods of use
The high pressure chamber of the oxygen valve is connected with the cylinder, the low pressure chamber is the gas outlet and leads to the use system. Indication of high pressure gauge is the pressure of gas stored in the cylinder. Low pressure gauge outlet pressure can be controlled by adjusting screw. Open the main switch while the oxygen valve is in use and then turn the low pressure gauge pressure adjusting screw clockwise to compress the main spring and drive the diaphragm, spring washer and ejector lever to open the valve. Such imports of high-pressure gas from the high-pressure chamber after throttling decompression into the low-pressure chamber, and through the exit leading to the working system. Turn the adjustment screw to change the height of the valve opening to regulate the passage of high-pressure gas and achieve the desired pressure value. Oxygen valve equipped with safety valve. It is to protect the pressure relief valve and make it safe to use the device, but also the valve failure signal device. If due to the valve pad, valve damage or for other reasons, resulting in the pressure on the outlet and rise above a certain allowable value, the safety valve will automatically open the exhaust. This type of valve in the pipeline should be generally horizontal installation. Oxygen valve to use: (1) according to different requirements, oxygen valve has many specifications. Most of the highest import pressure, the minimum import pressure of not less than 2.5 times the outlet pressure. The outlet pressure specifications are more, generally, the maximum outlet pressure is; (2) When installing the valve should be determined whether the connection specifications consistent with the cylinder and the use of the system connector. Pressure reducing valve and cylinder with hemispherical connection, by tightening the nut so that the two completely match. Therefore, the use of the two hemispherical surfaces should be kept clean to ensure a good airtight effect. Use high-pressure gas to blow off the dust before installation. If necessary, PTFE and other materials can also be used for gaskets; (3) Oxygen valve should be prohibited contact with grease, so as to avoid fire accidents; (4) stop working, the pressure relief valve should be more than net air release, and then loose adjustment Screw in order to avoid long-term compression deformation of the elastic element; (5) oxygen valve should avoid vibration, not with corrosive substances in contact.
