Mechanical Industry Standard of the People's Republic of China JB/T9576 2000-04-24 2000-10-01 JB/T9576 This standard is a revision of JB/Z188-82 Large Turbine Inlet Valve System. This revision has made the following 6 changes: 1 The discus type butterfly valve series in the original B/2188--82 series has been cancelled. 2 "2 Reference Standards" has been added. 3 "Nominal diameter" in the standard has been changed to "nominal diameter" 4A6 has added "Note: If the inner diameters on both sides are different, the smaller value shall be taken" 4 "Appendix A, B, C, D" have the same effect as the text. 6 Each table is added with the serial number of the newly designed door in recent years. This standard will replace JB/Z188-82 from the implementation date. This standard is proposed and managed by Harbin Large Electric Motor Research Institute. The drafting unit of this standard is Dongfang Electric Motor Co., Ltd. The drafter of this standard is Lin Hongde. The drafting group members of this standard are Li Zheng, Wang Xicheng and Shi Zenglian. 1 This standard is applicable to butterfly valves and ball valves for water inlet valves of large and medium-sized turbines. 2 Reference standards The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. At the time of publication of the standard, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the following standards to promote the latest version. GB/T14478-1993 Basic Technical Conditions for Inlet Valves of Large and Medium-sized Turbines 3 The nominal diameter and water level of the newly designed butterfly valve shall refer to the provisions of Table 1. Matters not specified in this standard shall comply with the provisions of GB6/T14478. If there are special requirements, the buyer shall negotiate with the manufacturer. Table 1! Butterfly valve series water section division Nominal diameter First water head section Nominal diameter of the newly designed ball valve Second water head section Third water head section First water head section Generally determined according to Table 2. Matters not specified in this standard shall comply with the provisions of GB/T14478. If there are special needs, they shall be determined by the ordering party and the manufacturer through consultation. JB/T95762000 Table 2 Ball valve series Nominal diameter 200 meters 5 Method for compiling water inlet valve models, basic parameters and basic dimensions, external dimensions of bypass valves and external drawings of water inlet valves. The method for compiling water inlet filter models, basic parameters and basic dimensions, external dimensions of bypass valves and external drawings of water inlet valves are shown in Appendix A, Appendix B, Appendix C and Appendix D Method for compiling valve serial numbers JB/T95762000 Instructions for compiling water inlet valve models Nominal diameter of valve (Gm) Type of operating mechanism Electrical layout The highest static water head that the valve can withstand (certificate) Valve type Valve type code is expressed in Chinese phonetic letters: A2 a) Flat butterfly valve PDF: 5 Ball valve QF, 3The highest static water head refers to the highest static water head that the horizontal center line of the valve can withstand after the valve is closed (unit: m) A3 Valve shaft arrangement is expressed in Chinese phonetic letters: A4 a) Horizontal shaft w: b) Vertical shaft L. A5Type of operating mechanism is expressed in Chinese phonetic letters: a) Hydraulic operation; b) Water music operation C C) Electric operation D; d) Manual operation S. A6 valve nominal diameter refers to the flow-following inner diameter of the body at the connection with the upstream and downstream pressure water pipes. (Unit: Cr) Note: If the inner diameters on both sides are not the same, the smaller one should be used. Flat type butterfly continues to read the base.
