Description

Technical Field

[0001] The utility model relates to the technical field of electric actuator connection components, and more specifically to an adjustable electric actuator connection mechanism. Background Art

[0002] An electric actuator is a driving device that can provide linear or rotational motion. It uses a certain driving energy source and works under a certain control signal. When the electric actuator connection mechanism is connected to the valve stem, the connection method is relatively cumbersome, which reduces the convenience of connection. In addition, the length of the electric actuator connection mechanism is fixed, and the connection position between the electric actuator and the valve stem cannot be compensated according to actual needs.

[0003] For example, the electric actuator and valve body connection mechanism disclosed in announcement No. CN220668529U includes an electric actuator body, a valve stem is provided on the top of the electric actuator body, a connecting tube is provided at the bottom of the valve stem, a support ring is fixedly connected to the top of the connecting tube, a screw rod is provided on one side of the support ring, one end of the screw rod passes through the support ring and the valve stem, threaded sleeves are provided on both sides of the support ring, a mounting plate is provided on the fixed sleeve on the valve stem, two second bolts are provided on the mounting plate, and the mounting plate and the connecting tube are fixed by the two second bolts.

[0004] It can be seen from the above-mentioned public scheme that after the connecting tube and one end of the electric actuator body are connected and fixed, the distance between the connecting tube and the electric actuator body is fixed and cannot be adjusted. When the position of the electric actuator body and the electric control valve is fixed, the distance between the connecting tube and the valve stem will change according to actual needs, making it difficult to install the electric actuator connecting mechanism and the valve stem, and the valve stem is connected to the screw rod through a thread, which not only requires drilling of the valve stem to reduce its strength, but also the threaded connection method is cumbersome and troublesome, which brings inconvenience to the connection.

The inner wall of the adjusting groove 21 is in contact with the surface of the rotating shaft 11, and the cross-sectional shape of the adjusting groove 21 is polygonal, which ensures the rotational stability of the adjusting rod 2 and the connecting sleeve 3. A slide groove 22 is connected to the side of the adjusting groove 21, and the inner wall of the slide groove 22 is in contact with the surface of the limiting rod 12, so that there is a linear sliding between the limiting rod 12 and the adjusting rod 2. Function: the side of the adjusting rod 2 is slidably connected to the limit rod 12, and the surface of the limit rod 12 is connected with a tightening knob 14 through a thread. One end of the adjusting rod 2 is fixedly connected to the connecting sleeve 3, and the interior of the connecting sleeve 3 is provided with a mounting groove 32. The inner wall of the mounting groove 32 is fixedly installed with an electromagnetic adsorption disk 4 and an anti-slip sleeve 33. The electromagnetic adsorption disk 4 is connected to a power control switch 41 through a wire. The electromagnetic adsorption disk 4 and the control switch 41 belong to the prior art and are used to power on and off the electromagnetic adsorption disk 4. The surface of the electromagnetic adsorption disk 4 contacts the end face of the clamping block 51. The clamping block 51 is made of iron metal. The electromagnetic adsorption force generated after the electromagnetic adsorption disk 4 is energized firmly fixes the clamping position of the clamping block 51. One end of the anti-slip sleeve 33 is slidably connected to the clamping block 51, and one end of the clamping block 51 is fixedly connected to the valve stem 5. The other end of the valve stem 5 is provided with an electric control valve body, which belongs to the prior art.

[0026] One end of the limit rod 12 is fixedly connected to the surface of the rotating shaft 11, and the surface of the limit rod 12 is slidably sleeved with a spring washer 13. The side surface of the spring washer 13 is in contact and extruded with the end surface of the tightening knob 14, and the other side surface of the spring washer 13 is in contact and connected with a plane 23. The plane 23 can increase the contact area with the spring washer 13, thereby ensuring the tightening stability of the tightening knob 14 on the limit rod 12.

[0028] When the adjustable electric actuator connection mechanism is connected to the valve stem 5 of the fixed electric control valve, the block 51 at one end of the valve stem 5 is first inserted downward into the connecting sleeve 3, so that the rear end surface of the block 51 inserted into the anti-slip hole 34 contacts the surface of the electromagnetic adsorption disk 4, and the limit ring 52 contacts the inner wall of the groove 31, and then the electromagnetic adsorption disk 4 is energized by the control switch 41, and the electromagnetic adsorption disk 4 is energized to generate an electromagnetic adsorption force to fix the position of the block 51, and then the electric actuator body 1 is moved downward to be connected and fixed with the fixing member. During the downward movement of the electric actuator body 1, the rotating shaft 11 and the limit rod 12 move downward, so that the total length of the rotating shaft 11 and the adjusting rod 2 increases. After the electric actuator body 1 is fixed, manually tighten the tightening knob 14 clockwise to fix the moving position of the limit rod 12, and then drive the valve stem 5 to rotate through the electric actuator to control the switch of the electric control valve.
