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 the angle valve and smell leakage, and observe whether the pointer changes. Every time you change the liquefied petroleum gas cylinder, you should check whether the sealing ring is intact. If deformed or damaged, replace before use. According to the analysis of poisoning and explosion accidents that occurred in the past, 60% of the accidents were caused by the failure of the pressure relief valve or the loss or damage of the rubber sealing ring. So let's learn our lesson and pay attention.
1. The breathing hole on the upper cover of the pressure reducing valve in the LNG gasifier is used to adjust the air volume, so that it has the function 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, and often clean the upper valve cover. However, during wiping with a rag, the breathing holes became clogged with debris, leading to accidents. Therefore, during the cleaning process, if the breathing hole is found to be blocked, you can use a thin iron wire to pierce it carefully, but do not pierce or damage the rubber membrane in the pressure reducing valve.
2. If the LNG vaporizer and its location do not meet the requirements, it may cause liquefied petroleum gas to flow into the pressure reducing valve, causing the rubber sealing ring to dissolve and expand, resulting in a small or blocked air intake gap, affecting 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 air leakage. Therefore, it should be checked regularly.
