Close wiring and adopt electromagnet action loop and motor operation reset loop interlock circuit, this circuit can play overload protection, separately
Outward, due to the presence of nonpolarity circuit module, both positive and negative polarity need not be distinguished when motor accesses circuit, hence in so that wiring behaviour
Make convenient, be also prevented from maloperation and lead to burn-down of electric motor.
In sum, the present invention is by installing runner in the direct current generator output shaft larger with speed reducing ratio, direct and convex
Wheel component coincide and rotates, thus driving executor's live spindle to control the keying of fire-protection valve.Executor's opened self-locking structure is adopted
Designed with advanced principle of cranking arm, structure is simple, self-locking is reliable, stable and executor's opening and closing time shortens, and executor moves
Make to adopt electromagnetic actuation action, this structure can reduce the suction to electric magnet and require, thus electric magnet can be made lower
Also action drives valve moment action can be turned off or under supply voltage.This executor carries overload protection work(using advanced
The circuit of energy, effectively prevents performer motor from damaging thus improving the reliability of executor, and executor's control power supply can be no
Polarity wiring (can be regardless of both positive and negative polarity wiring) is thus mis-wired can be avoided producing in engineering.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
