b) Added the term and definition of "linear drive device" (see 3:3); c) The flange codes and related dimensions of F05, F48 and F60 have been added (see Table 1 to Table 5); d) Added the expression method of the flange code (see Chapter 6); e) Increased the size of components that only transmit torque: Group C (see 7:4); f) Increased the size of components that only transmit torque: Group D (see 7:5); g) Increased the size of components that only transmit thrust: linear drive (group E) (see 7:6): This document is modified to adopt ISO 5210:2017 "Connection of multi-turn valve actuators for industrial valves": The technical differences between this document and ISO 5210:2017 and their reasons are as follows: --- ISO 273 (see 5:1) is replaced by GB/T 196 with normative references: The degree of consistency between the two documents is modified to suit It should meet the technical conditions of our country and meet the application needs of our country; --- Added the term and definition of "flange code" (see 3:6) to meet the needs of our country in practical applications; ---Change "Materials whose yield strength Re is less than or equal to:200MPa should be agreed upon by both parties" to "Yield strength Re less than The material of:200MPa should be negotiated by both the supplier and the buyer" (see 5:4) to meet the needs of practical applications in our country: The following editorial changes have been made to this document: ---Change the file name to "Connection of Multi-turn Valve Actuator"; --- Deleted references that did not appear in the text: Please note that some contents of this document may refer to patents: The issuing agency of this document assumes no responsibility for identifying patents: This document is proposed by China Machinery Industry Federation: This document is under the jurisdiction of the National Valve Standardization Technical Committee (SAC/TC188): This document is drafted by: Hefei General Machinery Research Institute Co:, Ltd:, Yangzhou Electric Power Equipment Repair Factory Co:, Ltd:, Changzhou Power Station Auxiliary Machinery Unit Co:, Ltd:, Chongqing Chuanyi Automation Co:, Ltd: Actuator Branch, Suzhou Borui Measurement and Control Equipment Co:, Ltd:, Zhejiang Xibosi Control Technology Co:, Ltd:, Huangshan Liangye Intelligent Control Co:, Ltd:, Tianjin Baili Ertong Machinery Co:, Ltd:, Yangzhou Vocational University, Zhuzhou Southern General Electric Co:, Ltd:, Jiangsu Suyan Valve Machinery Co:, Ltd:, Jiangsu Jiangyuan Machinery Co:, Ltd:, Jiangsu Dasheng Hydraulic Equipment Co:, Ltd: Company, Jiangsu Hongtai Petrochemical Machinery Co:, Ltd:, Zhejiang Bethel Technology Co:, Ltd:, Zhejiang Pump and Valve Product Quality Inspection Center, Baoyi Group Co:, Ltd:, Chengdu Chenggao Valve Co:, Ltd:, Jiangsu Wanheng Casting Co:, Ltd:, Ningbo Jack Long Seiko Co:, Ltd:, Zhejiang Hongxu Machinery Machinery Co:, Ltd:, Kairuite Valve Industry Co:, Ltd:, Jiangsu Xiongyue Petroleum Machinery Equipment Manufacturing Co:, Ltd: The main drafters of this document: Guo Huaizhou, Wu Yunguo, Tang Zhanfeng, Hu Chunyan, Jiang Yingxin, Shao Jie, Yang Zunping, Wang Wei, He Yi, Xiang Meigen, Hong Chunjie, Chen Huaxiang, Chen Jiusong, Xiao Changsong, Han Zhengdong, Han Xinlin, Wang Yin, Jiang Jinwei, Jin Keyu, Wang Yixiang, Zhang Xiaoxia, Tong Jun, Cao Qiao, Yan Rongjie, Jin Leixuan, Li Yunlong, Qiu Chen: The release status of previous versions of this document and the documents it replaces are as follows: ---It was first published as GB/T 12222-1989 in 1989, and it was revised for the first time in:2005; --- This is the second revision: Connection of multi-turn valve actuators1 ScopeThis document specifies the relevant requirements for the connection of multi-turn or linear actuators connected to valves: --- Flanges necessary for multi-turn drives connected to industrial valves [see Figure 1a)] or intermediate supports [see Figure 1b)] size; ---The structural form and size of the driving part of the multi-turn drive device necessary to connect with the driven part; --- The reference value of the size of the flange connecting surface directly connected with the industrial valve and the torque and thrust of the connecting flange: This document applies to the connection dimensions of multi-turn valve actuators and valves: Note 1: "Valve" in this document includes "valve with intermediate support" [see Figure 1b)]: Note 2: When the multi-turn driving device is composed of a multi-turn driving device and an integrated multi-turn gearbox or linear travel assembly, the connection is in accordance with this document Provisions, see Figure 1a) and Figure 1b): When the multi-turn drive is composed of a multi-turn drive with a separate multi-turn gearbox or linear When the assembly is composed, the connection of the multi-turn drive connected to the gearbox is in accordance with the provisions of this document, see Figure 1c) and Figure 1d): a) direct connection b) intermediate support connection c) combined direct connection d) combined intermediate support connection Description of index number: 1---Multi-rotary or linear driving device; 5---Gear box; 2---connection surface; 6---connection surface; 3---valve; 7---multi-turn drive device: 4--- There is a support connection in the middle; Figure 1 The connection surface between the multi-turn/linear drive device and the valve2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them, dated references For documents, only the version corresponding to the date is applicable to this document;
