The elimination adjustment valve divulges the key lies in the optimized adjustment valve structure the design, adjusts the valve according to the different craft condition reasonable choice the material, enhances adjusts the valve in production process quality control level, as well as adjusts the valve according to the craft operating system optimization the shaping. Along with the science and technology progress, specially the new material appearance, some new structures adjustment valves put into the use, their performance good, the life is long, may satisfy production the need to develop.

Therefore, we have the necessity also to have to take in the petroleum chemical industry production process to adjust the valve to divulge the question. Under causes the reason on the petroleum chemical industry installment in which the adjustment valve packing box divulges as well as prevented divulges the countermeasure, the method with the elimination makes the key discussion. 2 adjustments valves packing box divulges the reason analysis adjustment valve divulges divides into two kinds, namely outside divulges with the interior divulges. In the majority situation, outside divulges the consequence which creates, often divulges pared to the interior seriously. In the industrial production, adjusts the valve outside to leak not only creates the raw material and the energy waste, but also can directly pollute the environment, even causes the fire, the detonation, is poisoned and so on the harm safety significant accident, the national economy creates the heavy loss for. Outside but the packing box divulges also belongs leaks. The packing box divulges reason: The packing box by the stuffing box, the padding, the padding pad as well as the padding contracts the anization and so on to be posed. The stuffing box sets on the valve body or the valve cover, plays holds the padding the role. The padding pad sets to the stuffing box base, plays the strut padding role. The padding divides the soft nature sealing pound and takes shape the padding two kinds. Takes shape the padding take the elastic material quality as the raw material, uses the mould pressing to take shape or the turning processing makes each kind of joiner curtain under, pares, takes shape the padding structure pact, sealing property good, the serviceability is stronger. The medium divulges in the sealing pound place, the reason bees less crowded, the sealing pound for the padding gland is not strict, the padding variety or the quality does not conform to the requirement, the padding gets older or by the valve lever attrition. 3 adjusts the loss which the valve divulges creates Divulging causes which by the above situation, creates the economic loss and further because the medium characteristic different has differently to the environment pollution degree. If is the gas medium, then very easily p
