Prevention of leakage of pipe joints in the gas heater valve, both the metal pipe coupling, or Oven Gas Valve, are prone to leakage problems. For card sets of pipe joints, mostly due to the pipe by a large external force or impact, so that the card sleeve loose or deformed pipe ends and cause leakage, you should check whether the card holder out of round, whether the defect edge, whether the pipe end in good condition and the extent of compression ferrule nut, while also eliminating external piping. For flared Gas Heater Control Valve, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front end truncated. If the top male and female cones pressure seal, which is mostly due to two cone leak damage, available grinders for grinding cone. In some by "о" or outer-ring seal by the end face of the gas heater valve, the leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that the two-plane connection when the pressure is uneven or "о" ring is cut cause leakage; "о" ring uncompacted, insufficient amount of elastic deformation caused by leakage; "о" mouth-ring groove just too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, can also be sealed with a flat opening slot stop cutting or grinding to reduce the groove depth of mouth only, so "о" ring has sufficient amount of elastic Gas Control Valves (compression in general should be between 0.35-0.65mm). For the use of oil and rubber, wool felt, soft steel cardboard combination gasket sealant joints or pipe leaks, no matter what the material is, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.
