â–² JB/T8528-1997 general valve electric device technical conditions It is the latest standard of valve electric device, the standard was implemented in 1998-01-01. It is a revision of ZBJ16002-87 "Technical Conditions for Valve Electric Devices". According to the design, test, inspection and use practice of electric devices in recent years, the standard applies to 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.
▲ GB12222-89 multi-turn valve drive unit connection This standard is equivalent to the international standard ISO5210/1 ~ 5210 / 3-1982 "multi-turn valve drive connection". It specifies the connection size of the multi-turn valve actuator to the valve and the size of the drive, as well as the reference values ​​for torque and axial thrust. This standard applies to the connection size of valve actuation devices such as gate valves, globe valves, throttle valves and diaphragm valves.
At present, some electric device manufacturers in the world have the same connection size and type as the standard. The connection dimensions of our company's SMC, SCD and BA products meet the requirements of this standard.
â–² GB12223-89 partial rotary valve drive unit connection This standard is equivalent to the international standard ISO5211/1 ~ 5211/3-1982 "partial rotary valve electric device connection". It specifies the connection size of the partial rotary valve drive and the valve and the size of the drive, as well as the reference value of the torque. This standard applies to the connection size of valve actuators 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 partial rotation products conforming to the standard size can be provided according to user's requirements. The connection dimensions of products such as SMC/JA and valves can also be provided according to this standard.
â–² JB/T8862-2000 valve electric device life test procedure This standard specifies the test requirements, test items, test methods, etc. of the valve electric device life test. The life test in the type test of the valve electric device is still carried out according to the standard. JBZ247-85 is one of the reference standards of JB/T8528-1997 "Technical conditions for ordinary valve electric devices".
â–² JB/TQ53168-99 multi-turn valve electric device product quality classification This standard specifies the multi-turn valve electric device product quality grade, test method and sampling flattening method. The indicators for torque repeatability, life test, noise, etc. are specified, and three product quality grades of qualified products, first-class products, and superior products are specified.
â–²JB2195-77YDF series three-phase asynchronous motor for electric valve This standard is the first standard for valve-specific motor in China. It specifies the technical requirements, connection parameters and acceptance rules of the valve-specific motor. The specifications of the Limitorque motor used in the SMC series are relatively higher than those of the YDF series (ie, the SMC series does not use a YDF motor) and the standard has been revised.
