HQB series valve electric drive device is specially designed to meet the use requirements of nuclear power plant. It is suitable for valve disc rotating motion, such as ball valve, butterfly valve, etc. The product follows and meets the following standards:
1) IEEE382-1996 "IEEE Standard for Qualification of Actuators for Power Operated Valve Assemblies with Safety-Related Functions for Nuclear Power Plants" is equivalent to EJ/T531-2001 "Identification of Safety Valve Driving Devices for Nuclear Power Plants".
2) EJ/T 1022.11-1996 "Electric Valve Device for PWR Nuclear Power Plant".
3) NB/T20010.11-2010 "Valves of PWR Nuclear Power Plant Part 11: Electric Devices"
4) JB/T8528-1997 Technical Requirements for General Valve Electric Devices.
According to the working environment of nuclear power plant, the device can be divided into three types:
Type H1: Used in enclosure with accident, radiation and earthquake resistance. (Can also meet EJ/T 1022.11-96, NB/T 20010.11-2010 standard K1 environment)
Type H2: a) used in the containment, with radiation, earthquake resistance, accident-free environment; b) used outside the containment, affected by the accident, with radiation, earthquake-resistant environment. (Can also meet EJ/T 1022.11-96, NB/T 20010.11-2010 standard K2 environment)
Type H3: Used outside containment, no accident, no radiation, earthquake resistant environment. (Can also meet EJ/T 1022.11-96, NB/T 20010.11-2010 K3 environment)
