Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This revised standard adopts ISO 15761.2002 "oil and gas industry with a nominal size of less than or equal to DN100 steel gate, Globe and check valves. " This standard is based on ISO 15761.2002 redrafted. This standard and ISO 15761.2002 as compared to the main changes are as follows. --- With our standards instead of international standards of normative documents referenced; --- Remove the ISO 15761.2002 on the term, because the term has been defined in our standards and have the same meaning; --- The ISO 15761.2002 in the pound to PN level, the unit can also be modified accordingly; --- Not using ISO 15761.2002 5.4.4.3Class1500 valve structure length, according to China's valve provisions of the standard; --- Not using ISO 15761.2002 in 5.4.5, according to China's valve standards, thick-walled tube butt weld end requirements set out in the Appendix; --- Not using ISO 15761.2002, Chapter 8, according to China's existing, applicable to the petroleum and petrochemical valve inspection and test standards; --- Increased static life test frequency bellows valve stem seal requirements; --- Product testing according to the requirements of our country, increase the inspection rules; --- Added Appendix A; --- The ISO 15761.2002 Annex A, Annex D into the body, Appendix B and Appendix C after the merger as Appendix B of this standard; --- The ISO 15761.2002 welding end dimensions in Appendix C of this standard; --- Deleted Appendix E availability information. The standard proposed by China Machinery Industry Federation. The standard valve by the National Standardization Technical Committee (SAC/TCS188) centralized. This standard was drafted. Hefei General Machinery Research Institute, Anhui Tunxi High Pressure Valve Co., Ltd., Henan mountains Valve Co., Ltd., China East Valve Co., Bethel Valve Group Co., Ltd Baoyi group.
