This standard replaces GB/T 12236-1989 "General Steel swing check valve." And GB/T 12236-1989 compared to primary To change the following. --- Standard name was changed to "petroleum, chemical and allied industries steel swing check valve"; --- From the scope of application of the standard nominal pressure PN16 ~ PN160, nominal size DN50 ~ DN500 Nominal pressure to expand PN16 ~ PN420, nominal size DN50 ~ DN600; --- The original standard body minimum thickness requirement has been modified, a consolidation of the original wall thickness table two pressure systems, and expanded other The wall thickness of the pressure-diameter (1989 Version 4.1.2); --- Increased requirements for minimum diameter of the valve seat; --- Increasing the discharge port of the valve body requirements; --- Modify the seat requirement (1989 Version 4.1.8); --- Modify the seat surfacing alloy thickness requirements (1989 Version 4.1.8); --- Increased requirements vice elastic sealing; --- Modified valve surfacing alloy thickness requirements (1989 Version 4.3.1); --- Special accessories increased requirements; --- Increasing the welding end valve body material requirements; --- Modify the body and bonnet stud connection request (1989 Version 4.5); --- Information about the requirements of the elastic sealing life testing; --- Revised test methods, increase the type tests and requirements specified test methods; --- Modify the content of the flag, supply requirements; --- Adjustments to the original standard appendix A to the text, the contents of Appendix A to the "valve order contract data table." Appendix A of this standard is an informative annex. The standard proposed by China Machinery Industry Federation. The standard valve by the National Standardization Technical Committee (SAC/TC188) centralized. This standard was drafted. The Shanghai-Valve Co., Ltd., Hefei General Machinery Research Institute. The main drafters of this standard. Yang Hang, Wang Xiaojun. This standard replaces the standards previously issued as follows. --- GB/T 12236-1989.
