The triangular design of the ends of the collision rod 9993 increases the impact arm, so that the marbles 9994 obtain a larger initial speed; the elastic energy storage effect of the leaf spring 9995 prolongs the vibration time of the bell cover 9996 and improves the alarm persistence.

[0033] Normal working state in power-on state: the electromagnet 998 is powered on to generate a magnetic field, attracting the iron plate 997 to drive the rack 995 to slide forward, the third gear 994 rotates clockwise, the first rotating shaft 992 rotates clockwise synchronously, and the second gear 993 drives the first gear 93 to rotate counterclockwise.

[0034] Brake pad state: when the first gear 93 rotates counterclockwise, the inclined surface of the inclined sliding groove 94 pushes the guide column 97 to move outward, the sliding block 95 drives the brake pad 96 to move away from the valve rod 6, thereby releasing the brake and allowing the actuator 5 to normally adjust the valve rod pressure.

[0039] Dual power switching mechanism: electromagnet 998 and tension spring 996 form a power-on non-braking state, power-off trigger braking interlocking structure, without additional control circuit, only through the power on-off to achieve state switching, high reliability. Response components 99 and emergency alarm mechanism 9, alarm 999 share the first rotating shaft 992, realize the synchronous action of power-off, braking and alarm, to ensure the safety and maintainability of the heating system in emergency situations.

[0040] Working principle:

[0041] Step one, through the actuator 5 control valve stem 6 pressure, and then adjust the valve body 1 three-way pressure, adjust the fluid flow, and through the scale indication 7 display, temperature sensor 82 and fluid contact, the temperature signal into an electrical signal, and display on the display 83 shows the fluid temperature, real-time monitoring of fluid temperature;

[0042] Step two, electromagnet 998 power-on generates a magnetic field, through the attraction of iron plate 997 to make the rack 995 forward, under the transmission condition of the third gear 994 and the rack 995, let the first gear 93 be in the current position, the gap between the brake pad 96 and the valve stem 6, this is the normal working state without power-off;

[0043] Step three, when power failure occurs, the actuator 5 cannot work, the electromagnet 998 loses the magnetic field, under the action of the tension of the tension spring 996, the rack 995 moves backward quickly, the second gear 993 and the third gear 994 rotate synchronously counterclockwise, while the first gear 992 rotates clockwise, the sliding groove 94 inclined surface extrudes the guide column 97 inward, the sliding block 95 moves the brake pad 96 inward, the brake pad 96 holds the valve stem 6, and the valve stem 6 remains the current opening, so that the valve body 1 can still control the fluid flow in the short term;

[0044] Step four, the inertia of the second rotating shaft 9992 makes the striker 9993 rotate, the striker 9993 hits the marble 9994, the inclined surface of the striker 9993 makes the marble 9994 fly obliquely, the marble 9994 constantly hits the bell cover 9996, and the bell cover 9996 vibrates and makes a sound under the elastic action of the leaf spring 9995, reminding the staff of the power failure, so that the actuator 5 can be maintained in time.
