Description

Technical Field

[0001] This utility model relates to the field of actuator technology, specifically to an intelligent control signal conversion actuator for a directional valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. They have functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure.

[0003] However, existing directional valve actuators are usually used in sets, making independent disassembly and assembly difficult. They cannot adapt to directional valves of different sizes and specifications, resulting in low adaptability and increased operating costs. To address this, we propose an intelligent control signal conversion actuator for directional valves. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent control signal conversion actuator for a directional valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reversing valve intelligent control signal conversion actuator, comprising a housing, a lower sprocket rotatably connected to the right side inside the housing, blocking blocks slidably connected to both the upper and lower sides inside the lower sprocket, a rear turntable connected to the side of each of the two blocking blocks that are close to each other, a spiral disc connected to the left side inside the rear turntable, a front turntable rotatably connected to the left side of the rear turntable, multiple protrusions connected to the outer perimeter of the front turntable, pressing blocks slidably connected to the inner perimeter of the front turntable, the multiple pressing blocks being arranged in a cross shape, a support block connected to the right side of the pressing blocks, the right ends of the multiple support blocks extending into the interior of the spiral disc, a limit block connected to the rear left side of the front turntable, the limit block being L-shaped, a rotating rod rotatably connected inside the limit block, the rotating rod and the multiple protrusions being correspondingly arranged, and a transmission bar being arranged at the center inside the front turntable, the transmission bar being square.

[0006] As a further embodiment of this utility model: a motor base is connected to the inner top side of the outer shell, a connecting rod is connected to the drive end of the motor, a small gear is connected to the outer right end of the connecting rod, a large gear is meshed with the outer side of the small gear, one end of a connecting rod is connected to the inner center of the large gear, a large gear is connected to the outer side of the other end of the connecting rod, a small gear is meshed with the outer side of the large gear, one end of a connecting rod is connected to the inner center of the small gear, an upper sprocket is connected to the outer side of the other end of the connecting rod, and the upper sprocket and the lower sprocket are connected by a chain.

[0007] As a further embodiment of this utility model: two movable plates are slidably connected to the bottom right side of the outer casing, and both movable plates are connected to one end of the reversing valve housing by bolts.

[0008] As a further embodiment of this utility model: the right end of the transmission bar is connected to an internally threaded sleeve, a reversing valve housing is provided on the outer side of the internally threaded sleeve, a threaded piston is connected to the internal thread of the internally threaded sleeve, and sliders are connected to the upper and lower sides of the right side of the threaded piston, and both sliders slide inside the reversing valve housing.

[0009] As a further embodiment of this utility model: a movable block is connected to the side of the limiting block near the front turntable, and an annular groove adapted to the movable block is opened on the left side of the front turntable, and the movable block moves inside the groove.

[0010] As a further embodiment of this utility model: a slot adapted to the rotating rod is provided on the left rear part of the lower sprocket.

[0011] As a further embodiment of this utility model: handles are connected to both the front and rear sides of the left side of the front turntable, and the handles and the limiting blocks are staggered.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model uses a rotating rod inside a limiting block to rotate a convex strip that drives the front turntable to rotate. This causes multiple pressing blocks on support blocks to move around the transmission bar at the center for pressing and fixing. Then, through the transmission of the upper and lower sprockets, the threaded piston on the transmission bar can move left and right to provide the driving force required by the reversing valve. Due to the adjustability of multiple pressing blocks, it can adapt to reversing valve transmission bars of different sizes, improving the applicability of the device and reducing the cost of use when replacing the whole device.

[0014] 2. This utility model uses a motor to drive the small gear on the first connecting rod to rotate, which in turn drives the large gear on the second connecting rod to rotate. Since the large gear is connected to the small gear, the rotation of the small gear causes the upper sprocket on the third connecting rod to rotate, thus providing power to the lower sprocket. The whole system uses multi-stage gear reduction to improve the torque during driving. Furthermore, the mechanical connection of the multi-stage gears makes the connection structure more compact, improving transmission efficiency and load-bearing capacity.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 6This utility model discloses an intelligent control signal conversion actuator for a reversing valve, comprising a housing 1. A lower sprocket 12 is rotatably connected to the right side of the interior of the housing 1. Blocks 14 are slidably connected to both the upper and lower sides of the interior of the lower sprocket 12. A rear turntable 13 is connected to the side of each of the two block blocks 14 that are close to each other. A spiral disc 15 is connected to the left side of the interior of the rear turntable 13. A front turntable 16 is rotatably connected to the left side of the rear turntable 13. Multiple protrusions 17 are connected around the outer perimeter of the front turntable 16. Extrusion blocks 18 are slidably connected around the inner perimeter of the front turntable 16. The multiple extrusion blocks 18 are arranged in a cross shape. A screw is connected to the right side of each extrusion block 18. Support blocks 19, the right ends of multiple support blocks 19 extend into the interior of the spiral disk 15. The left rear part of the front turntable 16 is connected to a limit block 21, which is L-shaped. A rotating rod 20 is rotatably connected inside the limit block 21. The left rear part of the lower sprocket 12 has a slot 22 that matches the rotating rod 20. The rotating rod 20 and multiple protrusions 17 are correspondingly arranged. A transmission bar 23 is provided at the center of the interior of the front turntable 16. The transmission bar 23 is square. Two movable plates 28 are slidably connected to the bottom right side of the outer casing 1. Both movable plates 28 are connected to one end of the reversing valve housing 27 by bolts.

[0026] In Embodiment 1, the base of motor 2 is connected to the top inside of the outer casing 1. The drive end of motor 2 is connected to connecting rod 3. The outer side of the right end of connecting rod 3 is connected to pinion 4. The outer side of pinion 4 is meshed with large gear 5. The center of the inside of large gear 5 is connected to one end of connecting rod 6. The outer side of the other end of connecting rod 6 is connected to large gear 7. The outer side of large gear 7 is meshed with pinion 8. The center of the inside of pinion 8 is connected to one end of connecting rod 9. The outer side of the other end of connecting rod 9 is connected to upper sprocket 10. Upper sprocket 10 and lower sprocket 12 are connected by chain 11.

[0027] Specifically, starting the motor 2 drives the small gear 4 on the connecting rod 3 to rotate, which in turn drives the large gear 7 on the connecting rod 6 to rotate. Since the large gear 7 is connected to the small gear 8, the rotation of the small gear 8 causes the upper sprocket 10 on the connecting rod 9 to rotate. Through the transmission of the chain 11, the lower sprocket 12 is powered.

[0028] In embodiment 2, the right end of the transmission bar 23 is connected to an internal threaded sleeve 24, and a reversing valve housing 27 is provided on the outside of the internal threaded sleeve 24. The internal threaded sleeve 24 is connected to a threaded piston 25, and the upper and lower right sides of the threaded piston 25 are connected to sliders 26. Both sliders 26 slide inside the reversing valve housing 27.

[0029] Specifically, the rotation of the transmission bar 23 causes the threaded piston 25 inside the internal threaded sleeve 24 to move horizontally. Due to the limiting effect of the two sliders 26, the threaded piston 25 moves laterally horizontally to provide the driving force required by the reversing valve.

[0030] Working principle:

[0031] First, insert the transmission bar 23 into the center of the front turntable 16. Then, by rotating the rotating rod 20 inside the limiting block 21, the protrusion 17 drives the front turntable 16 to rotate. Because the rear turntable 13 is limited inside the lower sprocket 12 by the blocking block 14, the rear turntable 13 cannot rotate. At the same time, the spiral disc 15 on the rear turntable 13 also cannot rotate. This causes multiple support blocks 19 to move laterally along the spiral disc 15, driving the pressing blocks 18 on the multiple support blocks 19 to move around the transmission bar 23 at the center for pressing and fixing. This is to accommodate reversing valves of different sizes. After fixing, the threaded piston 25 on the transmission bar 23 can be driven to move left and right through the transmission of the upper sprocket 10 and the lower sprocket 12 to provide the driving force required by the reversing valve. After fixing, move the front turntable 16 and the limiting block 21 into the lower sprocket 12 for engagement, and then connect them via the magnetic strip on the limiting block 21. The sprocket 12 engages, and then, through the cooperation of bolts and two moving plates 28, one end of the reversing valve housing 27 is fixed, connecting the reversing valve housing 27 to the outer shell 1 for fixation. In use, the controller converts the electrical signal into a mechanical drive action, that is, the starter motor 2 drives the small gear 4 on the connecting rod 3 to rotate, which in turn drives the large gear 7 on the connecting rod 6 to rotate. Since the large gear 7 is connected to the small gear 8, the rotation of the small gear 8 causes the upper sprocket 10 on the connecting rod 9 to rotate. Through the transmission of the chain 11, the power is provided to the lower sprocket 12. Then, through the restriction of the limit block 21, the lower sprocket 12 drives the front turntable 16 and the transmission bar 23 limited by the squeeze block 18 to rotate, thereby causing the threaded piston 25 in the internal threaded sleeve 24 to move horizontally to provide the driving force required by the reversing valve. At this point, the entire working process is completed.
