Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a valve electric actuator, including valve 1 and driving machine 2, it is concrete, driving machine 2 is prior art, power supply to valve 1 switch in the current electric actuator, drive gear 3 has been cup jointed to driving machine 2's output shaft, the roof 4 of the side fixedly connected with U-shaped of driving machine 2, the bottom of roof 4 is rotated and is connected with rolling disc 5, the surface of rolling disc 5 is cup jointed the atress gear 6 with drive gear 3 meshing, adjusting mechanism 7 is passed through to rolling disc 5's bottom and is equipped with two supporting rods 8, it is concrete, adjusting mechanism 7 can make the position between two supporting rods 8 obtain changing, be equipped with limiting mechanism 9 between the bottom of supporting rod 8 and the rotating ring of valve 1, it is concrete, limiting mechanism 9 can make supporting rod 8 drive valve 1 rotating ring and rotate.

The scheme has the following working processes:

when valve 1 is used to needs, place driving machine 2 near valve 1 earlier, then make two supporting rods 8 adjust the position of swivel becket on valve 1 through guiding mechanism 7, fixedly connected with transfer line between swivel becket and the valve rod, later make supporting rod 8 and swivel becket synchronous rotation through limiting mechanism 9 and swivel becket, then make supporting rod 8 through limiting mechanism 9, start driving machine 2, the output shaft of driving machine 2 rotates and drives drive gear 3 and rotate, drive gear 3's rotation drives and rotates rather than the atress gear 6 of meshing, the rotation of atress gear 6 makes rotation 5 in the rotating disc of roof 4 bottoms follow the rotation, the rotation of rotating disc 5 makes two supporting rods 8 rotate, two supporting rods 8 drive the transfer line on the swivel becket through limiting mechanism 9 and rotate, thereby make the valve rod rotate and open or close valve 1.

According to the working process, the following steps are known:

when the driving machine 2 needs to be started to open and close the valve 1, the adjusting mechanism 7 and the limiting mechanism 9 can limit the rotating rings on different valves 1, so that the driving machine 2 can drive valves 1 of different models to rotate.

Further, guiding mechanism 7 is including offering the spout 701 that is the T shape in 5 bottoms on the rolling disc, and the inside sliding connection of spout 701 has two sliders 702, and the bottom and the 8 fixed connection of clamping rod of slider 702, it is specific, when the position of the clamping rod 8 of needs adjustment, need let slider 702 slide in spout 701 to make the clamping rod 8 of slider 702 bottom remove the position that different swivel beckets correspond.

Further, the holding tank 901 of locating the 8 bottoms of supporting rod is drawn together to the limiting mechanism 9, the inside of holding tank 901 has the gag lever post 903 that is the U-shaped through extrusion spring 902 elastic connection, inside the swivel becket of valve 1 is worn to locate by the gag lever post 903, it is concrete, before the 8 positions of supporting rod need be adjusted, extrude the gag lever post 903 upwards earlier, make the gag lever post 903 enter into the inside of holding tank 901, can not influence the adjustment to the 8 positions of supporting rod, release the gag lever post 903 after adjusting the position that corresponds, the gag lever post 903 inserts the swivel becket, drive the swivel becket through the transfer line on the swivel becket and rotate.

Further, the equal fixedly connected with in both sides of supporting rod 8 is the stiffener 904 of U-shaped, and the one end of stiffener 904 and the side laminating of regulating stem 903, it is concrete, when the power that stiffener 904 can produce when rolling disc 5 rotates transmits regulating stem 903, restrict regulating stem 903, prevent that regulating stem 903 and supporting rod 8 from rotating and leading to unable drive the rotating ring and rotate.

Further, the equal fixedly connected with in both sides of supporting rod 8 is triangular's boss 10, and the top and the 5 bottom laminating of rolling disc of boss 10, it is specific, boss 10 can increase supporting rod 8's intensity, prevents that supporting rod 8 and slider 702 from separately influencing the drive of supporting rod 8 to the swivel becket easily.

Further, one side of the slider 702 is rotatably connected with a T-shaped anti-moving rod 11 through a torsion spring rotating shaft 12, a plurality of anti-moving grooves 13 are formed in the inner side of the sliding groove 701, specifically, when the position of the slider 702 is adjusted, the anti-moving rod 11 can be rotated firstly, then the slider 702 is moved, the anti-moving rod 11 is released after the clamping rod 8 is moved to the corresponding position, and the anti-moving rod 11 is rotated through the elasticity of the torsion spring rotating shaft 12 to enter the adjacent anti-moving grooves 13, so that the slider 702 cannot slide.

In summary, when the valve 1 needs to be opened and closed, the driving machine 2 can be placed at an accessory of the valve 1, and then the adjusting mechanism 7 and the limiting mechanism 9 enable the driving machine 2 to drive the rotating rings of the valves 1 of different types to rotate, so that the valve 1 is suitable for different valves 1.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
