Liquefied petroleum gas cylinders leak during use can cause poisoning, fire and even explosion, causing huge losses to the life and property of the country and people. The majority of accidents were due to leakage of angle valves on LPG cylinders. According to the author’s practice, the following questions for reference. (1) Angular valve non-metallic seal material is poor, the performance does not meet the requirements, size, shape is not accurate, can not guarantee the sealing performance, should be promptly replaced. Metal forging or machining quality unqualified, should be scrapped. (2) Angle valve pad (nylon 1010, PTFE) flexibility is not
