An automatic diverting valve for vacuum pipelines

Abstract

This utility model discloses an automatic diverting valve for vacuum pipelines, relating to the field of fluid control technology. The utility model includes a main pipeline with a flow-direction changing mechanism and a disassembly mechanism on its outer wall. By incorporating a valve plate, when the fluid direction needs to be changed, a controller starts a motor, which rotates a threaded rod. The rotation of the threaded rod moves a fixed frame, which in turn moves an internal rack, causing a bidirectional rack to move. This movement of the rack moves the valve plate, which, when it reaches another branch pipeline, compresses a pressure plate, thereby compressing the telescopic rod and spring. This mechanism, through the threaded rod driving the valve plate, closes the branch pipeline, changing the fluid flow direction. Simultaneously, the pressure plate enhances the seal between the valve plate and the branch pipeline.

Description

Technical Field

[0001] This utility model belongs to the field of fluid control technology, and in particular relates to an automatic diverting valve for vacuum pipelines. Background Technology

[0002] As industrial production moves towards intelligence and automation, vacuum technology is widely used in many fields, such as semiconductor manufacturing, vacuum packaging, food processing, materials handling, and many research laboratories. In these systems, airflow needs to be precisely controlled between different pipes, especially to ensure that the system can switch the direction of airflow as needed without disrupting the vacuum environment.

[0003] When airflow needs to flow between different pipes, the pipes that do not require gas flow need to be sealed. If the sealing is not complete, airflow may partially pass through the pipes that should not be flowing, resulting in gas leakage, affecting the vacuum level or pressure stability of the system, and causing a decline in the performance of the entire system. Therefore, we propose an automatic diverting valve for vacuum pneumatic pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum pneumatic pipeline automatic diverting valve. Through the reaction force of the spring, the extrusion plate is squeezed, thereby squeezing the valve plate, which enhances the sealing performance of the valve plate for the pipeline and solves the problem that airflow may partially pass through the pipeline that should not be flowing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic diverting valve for vacuum pipelines, including a main pipeline, a flow direction changing mechanism provided on the outer wall of the main pipeline, and a disassembly mechanism provided on the outer wall of the main pipeline.

[0007] The flow-changing mechanism includes a transfer pipe fixedly connected to the outer wall of the main pipe, a branch pipe fixedly connected to the outer wall of the transfer pipe, a groove opened inside the transfer pipe, a valve plate slidably connected to the inner wall of the groove, a fixing frame snapped onto the outer wall of the valve plate, a fixing plate fixedly connected to the inner wall of the transfer pipe, a telescopic rod fixedly connected to the outer wall of the fixing plate, a pressing plate fixedly connected to the side of the telescopic rod away from the fixing plate, a spring fixedly connected to the side of the pressing plate near the telescopic rod, a clamping plate snapped onto the outer wall of the transfer pipe, a motor fixedly connected to the outer wall of the clamping plate, a threaded rod fixedly connected to the output shaft of the motor via a coupling, and a controller fixedly connected to the outer wall of the transfer pipe.

[0008] Furthermore, the end of the spring away from the extrusion plate is fixedly connected to the outer wall of the fixed plate, the telescopic rod is located inside the spring, the outer wall of the threaded rod is rotatably connected to the inner wall of the clamping plate, and the outer wall of the threaded rod is threadedly connected to the outer wall of the fixed frame.

[0009] Furthermore, the disassembly mechanism includes a bidirectional rack fixedly connected to the outer wall of the valve plate, the outer wall of the bidirectional rack being engaged with a rack, the outer wall of the rack being slidably connected to the inner wall of the fixed frame, and a sliding rod being fixedly connected to the outer wall of the rack.

[0010] Furthermore, the outer wall of the sliding rod is slidably connected to the inner wall of the fixed frame, and a second spring is fixedly connected to the side of the rack near the sliding rod, and the end of the second spring away from the rack is fixedly connected to the inner wall of the fixed frame.

[0011] Furthermore, a positioning block is fixedly connected to the outer wall of the transfer pipe, a positioning rod is inserted into the inner wall of the positioning block, the outer wall of the positioning rod is fixedly connected to the outer wall of the card plate, and a card block is fixedly connected to the outer wall of the card plate.

[0012] Furthermore, a second fixing frame is fixedly connected to the outer wall of the transfer pipeline, a second telescopic rod is fixedly connected to the outer wall of the second fixing frame, and a second locking block is fixedly connected to the outer wall of the second telescopic rod.

[0013] Furthermore, a spring three is fixedly connected to the side of the second locking block near the second telescopic rod, and the end of the spring three away from the second locking block is fixedly connected to the inner wall of the second fixed frame.

[0014] Furthermore, the telescopic rod two is located inside the spring three, and the outer wall of the locking block two is engaged with the outer wall of the locking block one.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a valve plate. When the fluid direction needs to be changed, the controller starts the motor, which drives the threaded rod to rotate. Simultaneously, the rotating threaded rod moves the fixed frame, which in turn moves the internal rack, causing the bidirectional rack to move. This movement of the bidirectional rack, in turn, moves the valve plate within the slide groove. When the valve plate reaches the location of another branch pipe, it compresses the extrusion plate, which in turn compresses the telescopic rod and spring. This mechanism uses the threaded rod to drive the valve plate, thus closing the branch pipe and changing the fluid flow direction. Simultaneously, the extrusion plate compresses the valve plate, enhancing the seal between the valve plate and the branch pipe.

[0017] 2. This utility model incorporates a positioning rod. When disassembly is required, the second locking block is moved in the opposite direction, thus compressing the second telescopic rod and the third spring. When the second locking block moves away from the first locking block, the locking plate is removed from the transfer pipe, causing the positioning rod to move away from the positioning block, and consequently, causing the first locking block to move away from the second fixed frame. After removal, the sliding rod is pulled in the opposite direction, causing the rack to move in the opposite direction. During this movement, the second spring is compressed, allowing the bidirectional rack to be removed from the two racks, thereby removing the valve plate. A new valve plate can then be replaced. This mechanism allows the valve plate to be disassembled and replaced, preventing wear and tear on the valve plate over time, which could damage the overall functionality of the device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The disassembly mechanism 3 includes a bidirectional rack 301 fixedly connected to the outer wall of the valve plate 204. The outer wall of the bidirectional rack 301 is engaged with a rack 302.

The outer wall of the rack 302 is fixedly connected to a sliding rod 303.

[0029] The outer wall of the sliding rod 303 is slidably connected to the inner wall of the fixed frame 205. A second spring 304 is fixedly connected to the side of the rack 302 near the sliding rod 303.

[0031] One specific application of this embodiment is:

[0032] When the fluid direction needs to be changed, the motor 211 is started by the controller 213, which drives the threaded rod 212 to rotate. As the threaded rod 212 rotates, it moves the fixed frame 205. This movement of the fixed frame 205, in turn, moves the internal rack 302, which in turn moves the bidirectional rack 301. This movement of the bidirectional rack 301, in turn, moves the valve plate 204 within the slide groove 203. When it reaches the position of another branch pipe 202, it compresses the extrusion plate 209, which in turn compresses the telescopic rod 207 and the spring 208. When the other branch pipe 202 is completely blocked, the reaction force of the spring 208 compresses the extrusion plate 209, which in turn compresses the valve plate 204, strengthening the valve plate 204's sealing performance. This mechanism, through the threaded rod 212 driving the valve plate 204, closes the branch pipe 202, changing the fluid flow direction. Simultaneously, the compression... Plate 209 presses against valve plate 204, thereby strengthening the seal between valve plate 204 and branch pipe 202. When disassembly is required, first move the second locking block 311 in the opposite direction to press the second telescopic rod 309 and the third spring 310. When the second locking block 311 moves away from the first locking block 307, the locking plate 210 is removed from the transfer pipe 201, driving the positioning rod 306 away from the positioning block 305, and then driving the first locking block 307 away from the second fixing frame 308. After removal, pull the sliding rod 303 in the opposite direction to drive the rack 302 to move in the opposite direction. During the movement, the second spring 304 is pressed, and then the bidirectional rack 301 can be removed from the two racks 302, thereby driving the valve plate 204 to be removed, and then a new valve plate 204 is replaced. This mechanism can remove and replace the valve plate 204 to prevent the valve plate 204 from wearing out due to prolonged use, which would damage the function of the entire device.
