Time:2021-11-12 17:28:49 writer:小編 PV:

Valves; standard; the status quo; Development
Valve products are widely used in petroleum, chemical industry, nuclear power, metallurgy,
electric power, water, large-scale coal-chemical industry, valves, increasing the total product, valve
technology continues to evolve, valve application areas are continuously expanding, and of the
corresponding valve standards are becoming increasingly underlines its importance. This article
describes the following aspects of the valve a standard development profile, system composition,
the standard status quo, to adopt international standards and developments.
1, China's valve industry to adopt international standards of
The adoption of international standards and the adoption of advanced foreign standards is an
important one standardization policies. Valve Standard is also actively implementing this policy, in
the basic standards, methods, standards and product standards with a large number of international
and foreign advanced standards, improve the standard of our valve technology.
(1) use of international standards
Corresponds to international standards for the valve to adopt international standards in table 1.
International Standard Serial Number International Standard Name (Chinese) corresponds to our
standard number
