For ease of use, this standard to make editorial changes as follows. --- In the "normative references", the required GB/T 1.1-2000 prepared to correspond to national standards instead of international standards Standards, and the use of reference are not dated; --- Added "Appendix NA (informative) thread series"; --- Remove the "References." This standard replaces GB/T 14038-1993 "cylinder intake port thread." This standard and GB/T 14038-1993 has compared the following differences. --- The standard name is changed. --- Original standard air intake provides thread series; in this standard in addition to the small size of the air inlet selection M3, M5, M7 common thread, its I choose G1/8 ~ G255 ° non-sealing pipe thread. --- Original standard applies only to cylinders Air inlet thread; This standard applies to all, including pneumatic components including a cylinder. --- Original standard only defines the inlet thread series; this standard increased the inlet end of the stud and performance requirements and test methods. This standard Annex A, Annex B, Appendix NA informative appendices. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of hydraulic and pneumatic (SAC/TC3) centralized. This standard was drafted. Shanghai Xinyi pneumatic Engineering Co., Ltd., Wuxi Institute of Technology Pneumatic Co., Ltd., Ningbo Guy Reiki motivation Mechanical Co., Ltd. Shanghai Camozzi pneumatic control components. The main drafters of this standard. Majoring enterprises Lee Fang, Yang Sui Ran, single Junbo, Fang Fu years. This standard replaces the standards previously issued as follows. --- GB/T 14038-1993.IntroductionIn the pneumatic system, the power is through a closed loop control and compressed air to pass. Each pneumatic components, mainly through the air inlet threaded stud and with the aid end fittings, to take over other types of pipe fittings to connect to each other. Air intake is Each pressure transmission element such as a necessary part of air source treatment unit, valves, pneumatic cylinders and other accessories and so on. Pneumatic connection Ports and stud ends1 ScopeThis standard specifies the dimensions and performance requirements Ports and stud ends with a pneumatic drive cylinder threads. The standard provides for self -90kPa ~ 1.6MPa pressure within the range of leak-proof connection of the reusable, efficient packing secret Sealing device. This standard applies to the threaded inlet and stud ends in pneumatic drive in the new design.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.
