Description

Technical Field

[0001] This utility model relates to the field of throttling orifice cover technology, and in particular to a throttling orifice cover with an adjustable flow guiding angle. Background Technology

[0002] In the industrial fields of petroleum, chemical, and energy transportation, throttling orifice covers are key components of fluid control systems, mainly used to achieve the functions of medium flow regulation, pressure control, and flow velocity distribution. Traditional throttling orifice covers typically consist of a cover body, a throttling orifice plate, and a fixed flow guiding structure. Their working principle is to generate resistance to the fluid through the throttling orifice, while using the fixed flow guiding structure to guide the fluid flow direction in order to achieve the purpose of stabilizing the flow field or controlling parameters. However, this type of throttling orifice cover has significant drawbacks. The fixed flow guiding angle leads to poor adaptability to different working conditions, which can easily cause problems such as fluid turbulence, excessive pressure drop, and high energy loss. Especially in complex working conditions that require dynamic adjustment, the limitations of the fixed flow guiding structure are more prominent.

[0003] To address the aforementioned issues, adjustable flow guide angle throttling orifice covers have emerged. The core definition of this type of device is a throttling device that dynamically adjusts the angle of the flow guide structure through mechanical and intelligent control methods. Its basic components typically include a main housing, a rotatable flow guide component, an angle adjustment mechanism, and a positioning assembly. Early adjustable flow guide angle throttling orifice covers used hydraulic cylinders or pneumatic cylinders to drive a linkage mechanism, achieving angle changes in the flow guide component. These devices were characterized by high driving force and fast adjustment speed. However, this technology required a complex power system, making it prone to leakage and difficult to maintain. To overcome these drawbacks, existing technologies utilize gear and rack meshing transmission, using an external drive to rotate the flow guide component and achieve angle adjustment. This technology is simple in structure and provides stable transmission. However, during long-term operation, wear may cause a decrease in adjustment accuracy, and it cannot continuously adjust the angle, resulting in poor practicality. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a throttling orifice cover with an adjustable flow guiding angle, which aims to improve the problems of poor practicality in the prior art, which may lead to a decrease in adjustment accuracy due to wear during long-term operation and cannot continuously adjust the angle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable flow guide angle throttling orifice cover, including a mounting shell, the front side of which is provided with a plurality of grooves, the inner wall of which is provided with a corner mechanism, and the top of the inner wall of the mounting shell is fixedly connected with a disassembly mechanism, the disassembly mechanism being used for disassembly and installation;

[0006] The corner mechanism includes multiple locking blocks, the outer wall of each locking block is slidably connected to the outer wall of the groove, a cover is fixedly connected to an adjacent side of the multiple locking blocks, a support frame is fixedly connected to the top of the cover, a drive assembly is provided on the front side of the support frame, and a flow guide assembly is provided on the inner wall of the cover.

[0007] As a further description of the above technical solution:

[0008] The disassembly mechanism includes a protective cover, the top of which is fixedly connected to the top of the inner wall of the mounting shell. A second motor is fixedly connected to the inner wall of the protective cover, and a gear is fixedly connected to the output end of the second motor. Multiple connecting components are provided on the outer wall of the gear.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a protective shell, the bottom of which is fixedly connected to the top of the support frame, and a motor is fixedly connected to the inner wall of the protective shell. A transmission assembly is provided at the output end of the motor.

[0011] As a further description of the above technical solution:

[0012] The transmission assembly includes a connecting plate. The left inner wall of the connecting plate is fixedly connected to the output end of the motor. A locking post is fixedly connected to the right side of the connecting plate. A lifting assembly is provided on the outer wall of the locking post.

[0013] As a further description of the above technical solution:

[0014] The lifting assembly includes a limiting groove, the inner wall of which is slidably connected to the outer wall of the locking post, and a pushing post is fixedly connected to the bottom of the limiting groove.

[0015] As a further description of the above technical solution:

[0016] The flow guiding component includes a rotating shaft, both the left and right sides of which are rotatably connected to the inner wall of the cover, and a flow guiding plate is rotatably connected to the outer wall of the rotating shaft.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the locking block is slid into the groove. By turning on the motor, the connecting plate drives the locking post to rotate. Since the locking post is slidably connected to the inner wall of the limiting groove, the locking post drives the limiting groove to rise and fall while rotating, which in turn drives the pushing post to rise and fall. The pushing post is fixedly connected to the middle of multiple guide plates, so the multiple guide plates can rotate around multiple rotating shafts, achieving the function of continuously adjusting the guiding angle and enhancing efficiency.

[0023] 2. In this utility model, by turning on the second motor, the gear rotates, which in turn drives the racks on both sides to move closer and further apart. When the two move away from each other, the sliding frames and baffles on both sides move away simultaneously, so that the baffles on both sides move away from the groove, allowing the cover to be installed and removed. When the two move closer together, they can block the groove, preventing the cover from falling off through the groove, thus achieving the function of quick installation and disassembly, which is convenient for maintenance.

The disassembly mechanism 3 is used for disassembly and installation, facilitating maintenance and component replacement of the orifice cover, improving the ease of use and maintainability of the equipment. The corner mechanism 2 includes multiple locking blocks. 202. The outer wall of the locking block 202 is slidably connected to the outer wall of the groove 4. The locking block 202 slides in the groove 4, so that the entire corner mechanism 2 can move relative to the mounting shell 1, providing a basis for subsequent adjustment of the guide angle. The top of the cover 201 is fixedly connected to the support frame 203, which supports the drive component 204 and ensures that the drive component 204 can operate stably. The drive component 204 is set on the front side of the support frame 203. The drive component 204 provides power to the guide component 205. Through the operation of its internal motor, it drives the related components to move, thereby realizing the adjustment of the guide angle.

[0035] Please see the appendix Figure 4 - Appendix Figure 5 The disassembly mechanism 3 includes a protective cover 301. The top of the protective cover 301 is fixedly connected to the top of the inner wall of the mounting shell 1. A second motor 302 is fixedly connected to the inner wall of the protective cover 301.

The function of the baffle 3052 is to block the groove 4 and prevent the cover 201 from falling out of the groove 4, thus ensuring the stability of the throttling orifice cover.

[0036] Specifically, the disassembly mechanism 3 includes a protective cover 301. The main function of the protective cover 301 is to protect the internal motor 302 from external dust, debris, etc., which could affect the normal operation of the motor 302. The top of the protective cover 301 is fixedly connected to the top of the inner wall of the mounting shell 1, ensuring the stability of the protective cover 301. A gear 303 is fixedly connected to the output end of the motor 302. The gear 303 rotates under the drive of the motor 302, thereby driving multiple connecting components 304 to move. Multiple connecting components 304 are provided on the outer wall of the gear 303. The connecting component 304 includes a rack 3041, which meshes with a gear 303. When the gear 303 rotates, the rack 3041 moves accordingly. Sliding components 305 are provided on both the left and right sides of the fixed frame 3042.

The outer wall of the right sliding frame 3051 is slidably connected to the inner wall of the fixed frame 3042. The sliding frame 3051 slides within the fixed frame 3042, ensuring the smoothness of its movement.

[0037] Please see the appendix Figure 2 - Appendix Figure 3 The drive assembly 204 includes a protective shell 2041. The bottom of the protective shell 2041 is fixedly connected to the top of the support frame 203. A motor 2042 is fixedly connected to the inner wall of the protective shell 2041. The motor 2042 is the core component of the drive assembly 204 and provides power for the adjustment of the entire flow guide angle. A transmission assembly 206 is provided at the output end of the motor 2042. The flow guide assembly 205 includes a rotating shaft 2052. The rotating shaft 2052 provides the basis for the rotation of the flow guide plate 2051. The left and right sides of the rotating shaft 2052 are rotatably connected to the inner wall of the cover 201. The outer wall of the rotating shaft 2052 is rotatably connected to the flow guide plate 2051. The flow guide plate 2051 changes its angle by rotating, thereby realizing the adjustment of the fluid flow guide angle.

[0038] Specifically, the drive assembly 204 includes a protective shell 2041, which protects the internal motor 2042 and prevents external factors from damaging it. The bottom of the protective shell 2041 is fixedly connected to the top of the support frame 203 to ensure its stability. The output end of the motor 2042 is equipped with a transmission assembly 206, which transmits the power of the motor 2042 to the guide assembly 205 to adjust the guide angle. The left and right sides of the rotating shaft 2052 are rotatably connected to the inner wall of the cover 201, so that the guide plate 2051 can rotate around the rotating shaft 2052.

[0039] Please see the appendix Figure 3 - Appendix Figure 5The transmission assembly 206 includes a connecting plate 2061. The left inner wall of the connecting plate 2061 is fixedly connected to the output end of the motor 2042. A locking post 2062 is fixedly connected to the right side of the connecting plate 2061. The locking post 2062 rotates under the drive of the connecting plate 2061 and interacts with the limiting groove 2071 to achieve lifting and lowering movement. A lifting assembly 207 is provided on the outer wall of the locking post 2062. The lifting assembly 207 includes a limiting groove 2071. When the limiting groove 2071 rises and falls, the pushing post 2072 moves accordingly, thereby driving the guide plate 2051 to rotate around the rotating shaft 2052. The inner wall of the limiting groove 2071 is slidably connected to the outer wall of the locking post 2062. The bottom of the limiting groove 2071 is fixedly connected to the pushing post 2072.

[0040] Specifically, the transmission assembly 206 includes a connecting plate 2061, which connects the motor 2042 and the locking post 2062, transmitting power from the motor 2042 to the locking post 2062. The inner left wall of the connecting plate 2061 is fixedly connected to the output end of the motor 2042, ensuring that the connecting plate 2061 can rotate with the output end of the motor 2042. A lifting assembly 207 is provided on the outer wall of the locking post 2062. The component 207 converts the rotational motion of the locking post 2062 into a lifting motion, thereby driving the guide plate 2051 to rotate. The lifting component 207 includes a limiting groove 2071. The inner wall of the limiting groove 2071 is slidably connected to the outer wall of the locking post 2062. The limiting groove 2071 restricts the movement trajectory of the locking post 2062, so that the locking post 2062 can slide in the limiting groove 2071 while rotating, driving the limiting groove 2071 to rise and fall, and pushing the post 2072 to be fixedly connected to the middle of the multiple guide plates 2051.

[0041] Working principle: The locking block 202 is slid into the groove 4. By turning on the motor 2042, the connecting plate 2061 drives the locking post 2062 to rotate. Since the locking post 2062 is slidably connected to the inner wall of the limiting groove 2071, the locking post 2062 drives the limiting groove 2071 to rise and fall while rotating, which in turn causes the pushing post 2072 to rise and fall. The pushing post 2072 is fixedly connected to the middle of multiple guide plates 2051, so the multiple guide plates 2051 can rotate around multiple rotating shafts 2052, achieving the function of continuously adjusting the guiding angle and enhancing efficiency.

[0042] By turning on motor 302, gear 303 rotates, which in turn drives racks 3041 on both sides to move closer and further apart. When they move further apart, sliding frames 3051 and baffles 3052 on both sides move away simultaneously, causing baffles 3052 on both sides to move away from groove 4, thus allowing cover 201 to be installed and removed. When they move closer together, they block groove 4, preventing cover 201 from falling off through groove 4, achieving the function of quick installation and disassembly, which is convenient for maintenance.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
