In order to use the LNG vaporizer safely, a pressure reducing valve should be installed on it, and soapy water can be brushed on the interface to check for leaks. For example, a pressure reducing valve with a pressure indicator can be used to close corner valves and odor leaks and watch the needle change. Every time you change the LPG cylinder, check whether the sealing ring is in good condition. If deformed or damaged, replace it before using it. According to the analysis of past poisoning and explosion accidents, 60% of the accidents are caused by the failure of the pressure reducing valve or the loss or damage of the rubber sealing ring. So let's learn from it and pay attention.
1. The breathing hole on the top cover of the pressure reducing valve in the LNG vaporizer is used to adjust the air volume so that it has the functions of reducing pressure and stabilizing the pressure, and will not be blocked. Some people don't pay attention when cleaning the pressure relief valve with a cloth, often cleaning the upper valve cover. However, during the wiping process with the rag, the breathing holes were blocked by debris, resulting in an accident. Therefore, during cleaning, if you find that the breathing hole is blocked, you can use a thin wire to carefully pierce it, but prevent piercing or damaging the rubber membrane in the pressure relief valve.
2. If the LNG vaporizer and its position do not meet the requirements, it may cause the liquefied petroleum gas to flow into the pressure reducing valve, resulting in the dissolution and expansion of the rubber sealing ring, resulting in a smaller or blocked intake gap, which affects normal use. In addition, the rubber sealing ring is a vulnerable part. After long-term use, due to the corrosive effect of liquefied petroleum gas, pits will appear, resulting in gas leakage. Therefore, it should be checked regularly.
