  Rules for using liquefied gas cylinder pressure reducer

  When we usually use liquefied gas cylinders, when used for a long time, there will be more or less equipment loss. At this time, we must not use it anymore. We should replace new parts in time, especially the pressure reducer. At that time, we should pay more attention. So let's talk about the rules for using the liquefied gas cylinder pressure reducer.


  The use of a pressure reducer should be carried out according to the following rules:

  1. Pressure reducers and pressure gauges for various gases must not be exchanged. For example, pressure reducers used for oxygen cannot be used in systems such as acetylene and petroleum gas.

  2. The pressure reducer must be kept clean. The pressure reducer must not be contaminated with grease or dirt. If there is grease, it must be wiped clean before use.

  3. Treatment of freezing of the pressure reducer. If the pressure reducer is found to be frozen during use, use hot water or steam to thaw it, and never use flame or red iron to bake it. After the pressure reducer is heated, the remaining water must be blown off.

  4. The action must be slow when deflating the oxygen cylinder or opening the pressure reducer. If the valve opening speed is too fast, the temperature of the gas in the working part of the pressure reducer will be greatly increased due to adiabatic compression. This may cause the parts made of organic materials such as rubber packing and rubber film fibrous liners to catch fire and burn out. The pressure reducer is completely burned out. In addition, due to the static sparks generated by the rapid deflation and the oil stain of the pressure reducer, it will also cause fire and burn the parts of the pressure reducer.

  5. Precautions before installing the pressure reducer and when opening the gas cylinder valve: Before installing the pressure reducer, slightly tap the bottle valve and blow off the dirt to prevent dust and moisture from entering the pressure reducer. When opening the gas cylinder valve, the gas outlet of the cylinder valve should not be aimed at the operator or others to prevent the high pressure gas from suddenly rushing out and hurting people. The joint between the air outlet of the pressure reducer and the gas rubber pipe must be tightened with annealed iron wire or clamp to prevent the danger of disengagement after air is supplied.

  6. Precautions during the loading and unloading of the pressure reducer and work: When loading and unloading the pressure reducer, attention must be paid to prevent the pipe joint thread from slipping, so as to prevent the screw from being loosened and ejected. During the work, you must pay attention to the pressure value of the working pressure gauge. When stopping work, loosen the pressure regulating screw of the pressure reducer, then close the oxygen cylinder valve, and slowly exhaust the gas in the pressure reducer, so as to protect the spring and the pressure reducing valve from damage. After the work, the pressure reducer should be removed from the gas cylinder and stored properly.>>>More LPG CYLINDER Products

  7. The pressure reducer must be regularly checked and repaired, and the pressure gauge must be checked regularly. This is done to ensure the reliability of pressure regulation and the accuracy of pressure gauge readings. During use, if the pressure reducer is found to have air leakage or the pressure gauge needle does not work well, it should be repaired in time.

  Now you should know the rules of using the pressure reducer. If you have any questions, you can contact us, thank you.
