It is located in the turbine ring, inside starting end and the spindle drive of the scroll spring coordinate, outside the scroll spring
Side head coordinates with transmission on the inside of the turbine ring, so as to can drive the rotation of scroll spring when the main axis, is stored up
Can, scroll spring discharge when can driving spindle rotate backward, realize valve reset.
Further, Electric Actuator spring return mechanism further includes worm screw, the outside of the worm screw and the turbine ring
It is meshed, driving turbine ring rotation is pre-tightened so that scroll spring is tightened or loosened.
Further, Electric Actuator spring return mechanism further includes the left limit for limiting the main axis angle
Bolt and right limit bolt, the bottom end setting protrusion of the main shaft so that when the main axis protrusion and left limit bolt or
Right limit bolt is in contact, and is limited to the rotational angle of main shaft by left limit bolt or right limit bolt.
Further, the worm screw coordinates with the turbine ring self-locking, and the worm screw can drive the turbine ring to rotate, institute
The worm screw cannot be driven by stating turbine ring, and turbine ring moves when scroll spring being avoided to reset, and influences reset effect.
The technique effect of invention：（1）The Electric Actuator spring return mechanism of the present invention is adopted compared with the existing technology
It is matched with scroll spring and turbine ring so that scroll spring can be driven to rotate when main shaft rotates forward, realize energy storage, scrollwork bullet
Spring lose restriction realize release when, can driving spindle rotate backward, realize valve reset；It is aided with worm screw, it can be achieved that scroll spring
Preload；Simultaneously because scroll spring does not stress when initial installation, installation is facilitated, can be rotated with negative direction in detaching products
Scroll spring is discharged, reduces operational risk by worm screw completely.

Specific implementation mode
Embodiment 1
As shown in Figure 1, the Electric Actuator spring return mechanism of the present embodiment, includes the main shaft with valve rod transmission cooperation
3, scroll spring 41, turbine ring 42, worm screw 43, main shaft 3 are set in scroll spring 41, and scroll spring 41 is set in turbine ring 42
Interior, the inside starting end of scroll spring 41 is fixedly linked with 3 lateral wall of main shaft, the outside end of the scroll spring 41 and turbine
The madial wall of ring 42 is fixedly linked, and worm screw 43 is meshed with the outside of turbine ring 42, so that main shaft 3 can drive scrollwork bullet when rotating
The rotation of spring 41 carries out energy storage, when worm screw 43 rotates, turbine ring 42 can be driven to rotate, and to drive scroll spring 41 to rotate, carries out
It pre-tightens.
Embodiment 2
As shown in Fig. 2, a kind of Electric Actuator of the spring return mechanism of Application Example 1, including by main shaft 3, scroll spring
41, the spring return mechanism 4 that turbine ring 42, worm screw 43 form, further includes brake motor 1, one-way driving mechanism, single-direction transmission machine
Structure includes the first transmission shaft 22, second driving shaft 23, first gear 24, freewheel clutch, and the first transmission shaft 22 is through first gear
24 coordinate with the transmission of brake motor output shaft 11, and second driving shaft 23 coordinates through unilateral bearing 21 and the transmission of the first transmission shaft 22,
And first transmission shaft 22 be meshed with the outer ring 21 of freewheel clutch 2, the inner ring 20 of second driving shaft 23 and freewheel clutch 2 is solid
It is fixed to be connected, so that brake motor 1 can drive second driving shaft 23 to rotate；Spring return mechanism 4 further includes second gear 31, is used for
The left limit bolt 34 and right limit bolt 33 of 3 rotational angle of main shaft are limited, main shaft 3 is through second gear 31 and second driving shaft 23
