According to the valve by the national standardization technical committee and the national standardization technical committee sponsored by the safety relief valve standard online bulletin notice, the ministry of industry and information technology 2014, 47 announcement released a batch of approved industry standards.
Related to the valve industry standards, a total of 13. Among them, 13 respectively in standard 5 is the new standard of alternative before, there are eight new standards.
Replacement of the five new valve standard as follows:
The JB/T 8473-2014 meter valve group instead of before the standard JB/T 8473-1996 ";
"JB/T 7927-2014 valve steel appearance quality requirements instead of before the standard JB/T 7927-1999, using the standard ANSI/MSS - SP - 55-2011, the MOD.
The JB/T 7928-2014 industrial valve supply requirements "instead of the previous standard JB/T 7928-7928;
The JB/T 8862-2014 valve electric device life test procedures "instead of the previous standard JB/T 8862-8862;
The JB/T 8530-2014 valve electric actuator model establishment method "instead of the previous standard JB/T 8530-1997.
And eight new valve standard is: "JB/T 12000-2014 thermal power of supercritical and ultra supercritical parameter pressure forged steel valves with technical conditions", "JB/T 12001-2014 thermal power of supercritical and ultra supercritical parameter valve General requirements ", "JB/T 12002-2014 steam turbine with extraction non-return valve", "JB/T 12003-2014" specification for cryogenic valve test device, the JB/T 12004-2014 low vacuum butterfly valve technical conditions ", "JB/T 12005-2014 valve with short tooth trapezoidal thread", "steel pipe welded ball valve, JB/T 12006-12006, JB/T 12007-2014 in the blast furnace TRT system with quick cut butterfly valve".
More than 13 new standard valve will begin in November 1, 2014 formally implemented. The implementation of the new standard will make up the gaps of the current standard, more conducive to give full play to the standardization in the valve industry in the development of technical support, to promote industrial transformation and upgrading of the valve.
