Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically to an adjustable valve electric actuator. Background Technology

[0002] An adjustable electric valve actuator receives command signals from a control system or sensor and uses a built-in electric motor drive mechanism to precisely adjust the opening or closing degree of the valve, thereby achieving precise control of key parameters such as fluid medium flow rate, pressure, and temperature. This actuator not only has a high degree of automation and intelligence, but also can flexibly adjust the valve status according to production needs, ensuring the stability and accuracy of the process flow. It plays an indispensable role in improving production efficiency, ensuring product quality, and achieving energy conservation and emission reduction.

[0003] During continuous operation, the coefficient of friction between workpieces increases. Existing electric actuators reduce wear by manually adding lubricating oil in stages, thereby extending the actuator's service life.

[0004] However, in actual use, the above-mentioned device requires frequent manual intervention to add lubricating oil in stages, which increases the inconvenience of operation and leads to low work efficiency. At the same time, the staff cannot accurately understand the actual condition of the lubrication system and find it difficult to formulate an effective maintenance plan, resulting in a decline in the performance of the actuator. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable electric valve actuator, which can effectively solve the problem that the operator cannot accurately understand the actual condition of the lubrication system and is difficult to formulate an effective maintenance plan, resulting in a decline in the performance of the actuator.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an adjustable electric valve actuator, including an electric actuator body. A first drive motor is provided at the top of the electric actuator body, and a rotating handle is provided at the bottom of the electric actuator body. An oiling groove is provided at one end of the electric actuator body near the rotating handle. An oiling pipe body is slidably connected to the oiling groove. A second drive motor is provided inside the oiling pipe body. A lead screw is provided at the output end of the second drive motor. A slider is threadedly connected to the lead screw. A connecting rod is symmetrically provided at the end of the slider away from the second drive motor. A compression plug is fixedly connected to the connecting rod. The end of the oiling pipe body away from the second drive motor is connected to the oiling groove.

[0008] Furthermore, the electric actuator body has a replenishment chamber inside, which is connected to an oil tank and a storage chamber.

[0009] Furthermore, a U-shaped block is provided inside the storage chamber, and a one-way valve is provided on the side of the U-shaped block away from the refueling pipe body.

[0010] Furthermore, a groove is provided on the inner wall of the refueling pipe body, and the groove is slidably connected to the slider.

[0011] Furthermore, the second drive motor is fixedly mounted on the support base, and the outer contour dimensions of the support base perfectly match the inner wall dimensions of the refueling pipe body.

[0012] Furthermore, the squeeze plug is slidably connected to the inner wall of the refueling pipe body, and an oil replenishment port is provided on the surface of the refueling pipe body.

[0013] Furthermore, the refueling pipe body has an oil outlet at the end away from the support base, and the oil outlet is connected to a refueling tank.

[0014] Furthermore, a maintenance cover is threadedly connected to one end of the refueling pipe body near the second drive motor, and a pull ring is movably connected to the maintenance cover.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] I. This utility model drives the lead screw to rotate through the output end of the second drive motor. The lead screw is connected to the slider through a threaded connection, which makes the slider slide stably along the inner wall of the oil filling pipe body. The slider drives the extrusion plug to slide synchronously through the connecting rod, thereby precisely extruding the lubricating oil in the oil filling pipe body and making it enter the oil filling tank through the oil outlet, providing the necessary lubrication for the electric actuator body.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] An adjustable electric valve actuator, see attached diagram. Figures 1-4The actuator includes an electric actuator body 1, a first drive motor 2 at the top of the electric actuator body 1, a rotating handle 18 at the bottom of the electric actuator body 1, an oiling groove 13 at one end of the electric actuator body 1 near the rotating handle 18, an oiling pipe body 14 slidably connected to the oiling groove 13, a replenishment chamber 11 inside the electric actuator body 1, the replenishment chamber 11 connecting the oiling groove 13 and a storage chamber 12, a U-shaped block 10 inside the storage chamber 12, a one-way valve 17 on the side of the U-shaped block 10 away from the oiling pipe body 14, the replenishment chamber 11 as a transfer station for lubricating oil, capable of receiving lubricating oil added from the oiling groove 13, and then the workpiece movement causes the lubricating oil to enter the storage chamber 12 from the top of the U-shaped block 10 away from the oiling pipe body 14, the lubricating oil is stored in the storage chamber 12, and subsequently the lubricating oil flows from the storage chamber 12 to the replenishment chamber 11 through the one-way valve 17 to provide lubricating oil for the workpiece, thereby achieving continuous and efficient operation.

[0028] Furthermore, a second drive motor 30 is installed inside the refueling pipe body 14. A lead screw 28 is installed at the output end of the second drive motor 30. A slider 27 is threadedly connected to the lead screw 28. A connecting rod 26 is symmetrically arranged at the end of the slider 27 away from the second drive motor 30. A compression plug 24 is fixedly connected to the connecting rod 26. A refueling groove 13 is connected to the end of the refueling pipe body 14 away from the second drive motor 30. A sliding groove 25 is formed on the inner wall of the refueling pipe body 14, and the sliding groove 25 is slidably connected to the slider 27. The second drive motor 30 is fixedly mounted on a support base 29. The outer contour dimensions of the support base 29 perfectly match the inner wall dimensions of the refueling pipe body 14. The compression plug 24 is slidably connected to the inner wall of the refueling pipe body 14. An oil filling port 23 is formed on the surface of the refueling pipe body 14. An oil outlet 22 is formed at the end of the refueling pipe body 14 away from the support base 29, and the oil outlet 22 is connected to the refueling groove 13. The second drive motor 30 drives the lead screw 28 to rotate through its output shaft. The threaded connection between the slider 27 and the slide block 25 allows the slider 27 to slide stably along the extension direction of the slide groove 25. The slider 27 drives the connecting rod 26 to slide synchronously, thereby causing the compression plug 24, which is fixedly installed on the 26, to slide on the inner wall of the filling pipe body 14. The compression plug 24 is provided with a sealing strip to further prevent lubricating oil from flowing back into the chamber of the compression plug 24 near the second drive motor 30, thereby squeezing the lubricating oil on the other side of the 24. Finally, under the action of the squeezing force, the lubricating oil enters the filling tank 13 through the oil outlet 22. In addition, the compression plug 24 is reset by controlling the rotation direction of the output shaft of the second drive motor, which is convenient for preparing for the next addition of lubricating oil. When it is necessary to replenish the lubricating oil in the filling pipe body 14, the seal on the oil replenishment port 23 is released and the oil outlet 22 is sealed. The output shaft of the second drive motor 30 is controlled to rotate in the opposite direction, so that the lubricating oil is smoothly drawn into the filling pipe body 14.

[0029] In addition, a maintenance cover 31 is threadedly connected to one end of the refueling pipe body 14 near the second drive motor 30. A pull ring 15 is movably connected to the maintenance cover 31. The maintenance cover 31 allows maintenance personnel to quickly and effortlessly open the cover to inspect and maintain the internal components, thereby extending the service life of the refueling pipe body and improving the user experience. The pull ring 15 is used to pull out the refueling pipe body 14, preventing the electric actuator from burning workers due to high surface temperature during prolonged operation, thus improving safety to a certain extent.

[0030] Working principle: During use, the first drive motor 2 drives the electric actuator body to open or close the valve. At the same time, when lubrication is required for the actuator, the second drive motor 30 drives the lead screw 28 to rotate through the output shaft, causing the slider 27 to slide stably along the slide groove 25. The slider 27 drives the squeeze plug 24 to slide on the inner wall of the oil filling pipe body 14 through the connecting rod 26, thereby squeezing the lubricating oil on one side of the squeeze plug 24, so that the lubricating oil enters the oil filling tank 13 through the oil outlet 22, then passes through the replenishment chamber 11, and finally flows into the storage chamber 12 for storage. The one-way valve 17 realizes the continuous supply of lubricating oil to provide necessary lubrication for the workpiece. When the oil filling pipe body 14 needs to be replenished with lubricating oil, the seal of the oil replenishment port 23 is released and the oil outlet 22 is sealed, and the output shaft of the second drive motor 30 is controlled to rotate in the opposite direction, so that the lubricating oil is smoothly drawn into the oil filling pipe body 14. In addition, the design of the inspection cover 31 and the pull ring 15 facilitates the maintenance personnel to inspect and maintain the internal components, improving the safety and service life of the equipment.
