HZD multi-turn electric valve-class nuclear device
Model: Example: H1ZD90-96, H1-type, to rque 900N m, speed 96r/min
Product Description:
HZD Series 1E-level valve electric device (hereinafter referred to
as Denso class 1E) fo r the use of nuclear power plants to meet the
requirements of specially designed double-valve power-driven
devices, applied to do a straight line valve flap valve movement,
such as the cut-off valves, valve , Throttle, Valves, and so on.
And follow the products meet the following criteria:
1) IEEE Std 382-1996 "IEEE Standard fo r Qualification of Actuato
rs fo r Power Operated Valve Assemblies with Safety-Related
Functions fo r Nuclear Power Plants", equivalent to EJ/T531-2001
"-class nuclear power plant safety valve device driver
identification . "
2) EJ/T1022.11-1996 "pressurized water reacto r nuclear power plant
valve electric device."
3) JB/T8528-1997 "common-valve electric device technology."
Acco rding to the installation of the nuclear power plant wo rk
environment, is divided into three types:
-Based H1: fo r release inside the containment, accident,
radiation, anti-earthquake conditions. (EJ/T1022.11-96 also be able
to meet the standards in the environment catego ry K1)
H2 type: (a). Fo r the release inside, and radiation,
anti-earthquake, accident-free environment; (b). Fo r the safety of
the shell, affected by the accident, radiation, anti-earthquake
conditions. (EJ/T1022.11-96 also be able to meet the standards of
K2 in the environment catego ry)
H3-type: security fo r the shell, without the effects of the
accident, radiation-free, anti-earthquake conditions.
(EJ/T1022.11-96 also be able to meet the K3 in the environment
catego ry)
