Domestic marine valve standard what are the problems, but also how to effectively solve these problems?
Marine valve variety specifications, which is its characteristics, but also hinder the valve technology to improve the problem.
Large variety, size, valve standard for the preparation, revision, drawing, organization of specialized production, valve quality control and so bring a series of difficulties.
Marine valve manual, our most commonly used standards are: GB / T584, GB / T585, GB / T586, GB / T587, GB / T588, GB / T589, GB / T590, GB / T591, GB / T592 and so on. These standard valves according to the nominal pressure of each valve can be divided into 2-6 varieties. For construction convenience, we usually choose the same nominal pressure level. In these types of standards, the same caliber valve shape, size are similar, according to this feature, whether the standard can be compressed? The differences between these standard valves are grouped together and categorized as: cast steel, bronze and cast iron. The unity of the valve standard, only the difference between material, would not it be 9 standard compressed into 3 standards? If the valve parts and then reasonable consolidation, to expand the generalization of the specification, the expansion of valve products batch, improve valve quality control is not it more favorable?
If all marine valves marine standards according to flange valves, threaded valves, plug ball valves, safety valves, pressure reducing valves, regulating valves, gate valves, butterfly valves and other classification; according to the applicable media, operating temperature, nominal pressure and other classification.
Comprehensive analysis, the merger of similar items, reorganization, which will be a major marine valve standards reform.
