Description

Technical Field

[0001] This utility model relates to the technical field of multi-turn electric actuators, specifically a multi-turn electric actuator with adjustment function. Background Technology

[0002] In the field of valve control, unlike traditional valve opening and closing devices, multi-turn electric actuators are a type of efficient and flexible drive device. During operation, the electric motor drives the screw, which in turn pushes the piston of the actuator to move up and down, thereby achieving precise control of the rotation angle. This type of multi-turn electric actuator significantly improves the operational stability of the equipment through its adjustable function and multiple protection mechanisms.

[0003] Currently, existing multi-turn electric actuators with adjustable functions require assembly before use, mainly by tightening multiple bolts to stably attach them to the valve body. However, considering that manual alignment is required during the tightening process, the actual assembly operation may be complicated, laborious, and time-consuming, and may also lead to problems such as low assembly accuracy and low installation efficiency. Therefore, to address the above issues, a multi-turn electric actuator with adjustable functions is proposed. Utility Model Content

A first flange is fixedly connected to the bottom of the lower sleeve. Side arc frames are fixedly connected to both sides of the top of the first flange. A flipping block is rotatably connected to the inner side of the side arc frame.

A pressure ring is fixedly connected to the top of the spring. Side arc plates are fixedly connected to both sides of the pressure ring.

[0007] Preferably, a digital display control module is fixedly connected to the front end of the transmission compartment, an upper sleeve is connected to the top of the transmission compartment, and a manual wheel is rotatably connected to the top of the upper sleeve.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A multi-turn electric actuator with adjustable function includes a transmission housing 1. The bottom of the transmission housing 1 is connected to a lower sleeve 2. The bottom of the lower sleeve 2 is fixedly connected to a first flange 3. The top two sides of the first flange 3 are fixedly connected to side arc frames 5. The inner side of the side arc frames 5 is rotatably connected to a flip block 6. The side of the flip block 6 away from the inner depth of the side arc frames 5 is fixedly connected to a limiting bracket 7. The vertical end of the limiting bracket 7 is threadedly connected to an adjusting screw 8. The bottom end of the adjusting screw 8 is fixedly connected to a buckle plate 9. A torsion spring 10 is sleeved on the outer side of the connecting part of the flip block 6. The top of the flip block 6 abuts against a pressure rod 11 extending into the side arc frames 5. A spring 12 is sleeved on the upper outer side of the pressure rod 11. The top of the spring 12 is fixedly connected to a pressure ring 14. Side arc plates 13 are fixedly connected to the left and right sides of the pressure ring 14.

[0021] like Figure 1 and Figure 2As shown, a digital display control module 18 is fixedly connected to the front end of the transmission housing 1. An upper sleeve 16 is connected to the top of the transmission housing 1. A manual wheel 17 is rotatably connected to the top of the upper sleeve 16. Before installing the multi-turn electric actuator, the manual wheel 17 can be rotated clockwise to adjust the valve stem hidden inside the transmission housing 1 so that it can be extended outwards for subsequent assembly work. The bottom of the first flange 3 abuts against the second flange 4. The bottom of the second flange 4 is provided with a valve sleeve 15 that is connected to the inside of the lower sleeve 2. The second flange 4 and the first flange 3 are bolted together. After the first flange 3 and the second flange 4 are pressed and pre-positioned, the first flange 3 and the second flange 4 can be fixed together by multiple bolts to complete the corresponding assembly and fastening work.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner surface of the side arc plate 13 and the outer surface of the side arc frame 5 are in contact. The top end of the side arc frame 5 and the bottom end of the spring 12 are fixedly connected together. The pressure ring 14 is sleeved on the outside of the lower sleeve 2, and the pressure ring 14 and the spring 12 are slidably connected together. The top end of the spring 12 and the bottom end of the pressure ring 14 are fixedly connected together. This structure mainly serves to assist the operator in pressing down the flip clamping structure. One end of the flip block 6 is fixedly connected to one end of the torsion spring 10, and the other end of the torsion spring 10 is fixedly connected to the inner surface of the side arc frame 5. There are two sets of torsion springs 10, with two springs in each set. The bracket 7 is L-shaped, and the adjusting screw 8 is T-shaped. The top surface of the buckle plate 9 and the bottom end of the second flange 4 are in contact. The pressure rod 11 and the side arc frame 5 are slidably connected up and down. The adjusting screw 8 is T-shaped, which can prevent the adjusting screw 8 from loosening downwards when rotating.

[0023] Workflow: The electrical energy required for the device to start and run in this utility model comes from an external power source. Before using the device, it is necessary to establish a wireless communication connection between the digital display control module 18 and the main control system. Before adjusting and controlling the flow control valve through the main control system, the multi-turn electric actuator needs to be installed. When the operator rotates the manual wheel 17 clockwise, the valve stem is screwed out, which extends outward through the interior of the lower sleeve 2 and the first flange 3. This valve stem screwing out is a publicly disclosed prior art. First, under the connection limitation of the lower sleeve 2, the pressure ring 14 is pressed down to compress the spring 12. The two pressure rods 11 will push the protruding end of the flip block 6 downward into the interior of the side arc frame 5. The two flip blocks 6 will flip outward with the limiting bracket 7, adjusting screw 8 and buckle plate 9. The torsion spring 10 deforms, and the operating gap between the two flip blocks 6 will change. After aligning with the multiple fixing holes on the surface of the second flange 4, the multi-turn electric actuator is placed. When the first flange 3 and the second flange 4 are positioned above the second flange 4, and the upper and lower holes of the first flange 3 and the second flange 4 are aligned and tightly connected, the pressure ring 14 can be released first. The spring 12 will start to reset and release, pulling the pressure rod 11 outward to reset. The push on the flipping block 6 can be removed. Under the connection limitation of the side arc frame 5, the torsion spring 10 will also start to reset and release, so that the two flipping blocks 6 will start to reset and flip along with the limiting bracket 7, the adjusting screw 8 and the buckle plate 9. After flipping into place, the two flipping blocks 6 will be adjusted from the original tilted state to the vertical state. Then, the adjusting screw 8 will be turned upward, and the buckle plate 9 will move upward. After moving into place, the buckle plate 9 will, together with the limiting bracket 7, pre-fix the first flange 3 and the second flange 4 that are connected together from bottom to top, so that the two are pre-positioned before bolt fixing. Afterward, only the bolt fixing parts need to be tightened to fix the first flange 3 and the second flange 4 together. The multi-turn electric actuator can then be installed on the valve sleeve 15.
