Abstract
A rotary power-off spring restorer is applicable to the power off and restoration of an electric actuation mechanism. The rotary power-off spring restorer comprises an electromagnetic clutch arranged in a bracket, wherein a ratchet mechanism is arranged on a driving wheel of the electromagnetic clutch; and a return spring mechanism matched with the driven gear is arranged on the driven gear of the electromagnetic clutch. The rotary power-off spring restorer is mounted between the electric actuation mechanism and a rotary valve; when the actuation mechanism is electrified to actuate, the actuation mechanism drives the rotary power-off spring restorer to rotate, and the rotary power-off spring restorer drives the valve to rotate, so that the 90-degree opening motion of the valve is realized. When a power supply is disconnected, internal mechanisms of the rotary power-off spring restorer are separated, the return spring mechanism drives the valve to rotate, and the 90-degree closing motion of the valve is realized. The rotary power-off spring restorer is simple in structure, is convenient in operation, low in investment and is reliable in operation.

Embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
As shown in Figure 1, rotary type dead electricity spring reset device mainly is made up of driving shaft 1, ratchet mechanism 2, magnetic clutch 3, support 4, Returnning spring mechanism 5.Wherein: magnetic clutch 3 is located in the support 4, and ratchet mechanism 2 is located on the driving shaft 1 of magnetic clutch 3, and the central shaft 5-3 of Returnning spring mechanism 5 links to each other with the driven gear of magnetic clutch 3.Described Returnning spring mechanism 5 comprises shell 5-1, is located at the central shaft 5-3 in the shell 5-1; Both sides, the front and back dislocation of central shaft 5-3 is provided with the tooth bar 5-2 that matches with central shaft 5-3 relatively; The bilateral symmetry of central shaft 5-3 is provided with spring seat 5-5, is provided with many group spring 5-6 in the spring seat 5-5, and organizing spring 5-6 can be two groups more; Also can be three groups or four groups, be three groups shown in the figure.The left and right sides of shell 5-1 is respectively equipped with the pretension screw 5-4 that is used to adjust spring seat 5-5 position, and is as shown in Figure 2.Described ratchet mechanism 2 comprises ratchet housing 2-4, is located at the single direction ratchet 2-5 in the ratchet housing 2-4; Ratchet housing 2-4 radially is provided with and is the thimble 2-3 that cross-shaped symmetrical matches with single direction ratchet 2-5 ratchet; Thimble 2-3 is provided with thimble spring 2-2; Thimble spring 2-2 is located in the spring compressor 2-1 that is fixed on the ratchet housing 2-4, and is as shown in Figure 3.
Working principle and working procedure: according to the output torque of the needed moment of rotation design of valve closing rotary type dead electricity spring reset device; Rotary type dead electricity spring reset device is linked to each other with valve with electric actuator; Position according to the desired shut-in time adjustment of valve pretension screw; Change the elastic force of the initial pretension state of spring, make to reach matching status cooperating between rotary type dead electricity spring reset device and valve and the electric actuator.Rotary type dead electricity spring reset device is installed between rotary type actuator and the rotary type valve; When actuator's energising action; Actuator drives the rotation of rotary type dead electricity spring reset device, and rotary type dead electricity spring reset device drives the valve rotation, realizes 90 degree breakdown actions of valve.When power supply was lost, rotary type dead electricity spring reset device internal mechanism separated, and Returnning spring mechanism drives the valve rotation, realized 90 degree closing motions of valve.
Driving shaft 1 whenever clockwise rotates 90 degree, and ratchet mechanism 2 gets into the plugging position, and at this moment, driving shaft 1 can't rotate counterclockwise.Under the power supply nominal situation, electric actuator drives driving shaft 1 and clockwise rotates ratchet mechanism 2 proper functioning; Magnetic clutch 3 is charged; Its driven gear and its driving shaft are synchronous, drive Returnning spring mechanism 5 simultaneously and rotate, and spring 5-6 changes the state of suppressing over to by initial pretension state.Rotate 90 down when spending when driving shaft 1 drives at electric actuator, the 5 central shaft 5-3 of Returnning spring mechanism rotate 90 degree synchronously, realize 90 degree unlatchings of valve.Valve opening signal stops electric actuator and rotates.Driving shaft 1 no longer receives moment of rotation, and ratchet mechanism 2 gets into the plugging position, and magnetic clutch 3 is normally charged, and Returnning spring mechanism 5 gets into the state of suppressing, and 5 pairs of magnetic clutchs 3 of Returnning spring mechanism, ratchet mechanism 2 effects rotate counterclockwise moment.But because ratchet mechanism 2 gets into the plugging position, ratchet mechanism 2, magnetic clutch 3, Returnning spring mechanism 5 can't be accomplished rotate counterclockwise action, make valve be held open state always.When power supply is lost, magnetic clutch 3 dead electricity, its driven gear separates with its driving shaft, and the output of Returnning spring mechanism 5 rotates counterclockwise moment, and its central shaft rotates counterclockwise 90 degree, realizes the closing motion of valve.
