Valve electric device ▲JB/T8528-1997 general valve electric device technical conditions It is the latest standard for valve electric device, which was implemented in 1998-01-01. It is the revision of ZBJ16002-87 'Technical Conditions of Valve Electric Device'. According to the design, test, inspection and use practice of electric devices in recent years, this standard is the latest standard for valve electric devices in ZBJ16002-87 working environment temperature valve electric device ▲ JB/T8528-1997 ordinary valve electric device technical conditions , The standard was implemented on January 1, 1998. It is the revision of ZBJ16002-87 'Technical Conditions of Valve Electric Device'. According to the design, test, inspection and use practice of electric devices in recent years, this standard has the working environment temperature, noise index, starting torque, maximum torque, control torque, control speed and test methods in ZBJ16002-87. Revised. Its implementation will replace ZBJ16002-87.  ▲Connection of GB12222-89 multi-turn valve drive device    This standard is equivalent to the international standard ISO5210/1~5210/3-1982 'Connection of multi-turn valve drive device'. It specifies the connection size of the multi-turn valve drive device and the valve, the size of the drive part, and the reference value of torque and axial thrust. This standard is applicable to the connection dimensions of valve drive devices such as gate valves, globe valves, throttle valves and diaphragm valves.   At present, the connection size and type of some electric device manufacturers in the world are the same as the standard. The connection dimensions of our SMC, SCD, and BA products meet the requirements of this standard.  ▲Connection of GB12223-89 part-turn valve drive device   This standard is equivalent to the international standard ISO5211/1~5211/3-1982 'Connection of Part-turn Valve Electric Device'. It specifies the connection size of the part-turn valve drive device and the valve, the size of the drive part, and the reference value of the torque. This standard applies to the connection size of valve drive devices and valves for ball valves, butterfly valves and plug valves.   The connection size of HBC series products is different from this standard, but SMC/HBC part-turn products that meet the standard size can be provided according to user requirements, and the connection size of SMC/JA and other products and valves can also be provided according to this standard.  ▲ JB/T8862-2000 Valve Electric Device Life Test Regulations   This standard specifies the test requirements, test items, test methods, etc. of the valve electric device life test. The life test in the valve electric device type test is still carried out in accordance with the regulations of this standard. JBZ247-85 is one of the cited standards of JB/T8528-1997 'Technical Conditions for Common Valve Electric Devices'.  ▲JB/TQ53168-99 Multi-turn valve electric device product quality classification    This standard specifies the product quality grade, test method and sampling method of multi-turn valve electric device. It stipulates the indexes of torque repeatability, life test, noise and other items, and stipulates the three product quality levels of qualified product, first-class product, and excellent product.  ▲Three-phase asynchronous motor for JB2195-77YDF series electric valve  This standard is the first standard for valve-specific motors in our country. It specifies the technical requirements, connection parameters, and acceptance rules of valve-specific motors. The technical parameters of the Limitorque motor used by the SMC series are relatively higher than those of the YDF series, (that is, the SMC series does not use YDF motors), so the standard has been revised
