Description

Technical Field

[0001] This utility model belongs to the field of industrial pipeline valve technology, and in particular relates to a precision positioning eye valve. Background Technology

[0002] Coal preparation mills utilize high-temperature exhaust gas from the kiln tail to dry raw coal. Valves are added at the kiln tail, typically louvered valves. These louvered valves are installed between the kiln tail ID fan outlet and the chimney. On one hand, the valves precisely control the exhaust gas volume, ensuring efficient and stable drying and improving the quality of the dried raw coal. On the other hand, during kiln shutdown and maintenance, the valves can cut off gas flow within the pipeline, and blind flanges are inserted on the upper flanges of the louvered valves to effectively isolate harmful gases such as CO, reducing the risk of poisoning for maintenance personnel. However, installing and removing blind flanges is difficult due to the pressure of the pipeline's own weight and the small gap between the two flanges, posing risks of CO poisoning and falls from heights. If the valves added at the kiln tail are replaced with eye valves, the valve plates may leak CO due to inaccurate positioning, requiring repeated adjustments. Furthermore, impurities easily accumulate on the valve plates, affecting the valve's sealing performance and normal operation. Utility Model Content

[0003] The purpose of this utility model is to provide a precise positioning eye valve to solve the problems of inaccurate valve plate positioning and easy accumulation of impurities in the louver valve during coal preparation mill maintenance due to the downward pressure of the pipeline and the small gap between the two flanges.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A precision-positioning eye valve includes a support platform and a pipe. The eye valve is installed on the pipe. A valve plate is slidably connected to the inner wall of the middle part of the eye valve. Support blocks are fixedly connected to both sides of the valve plate. A cleaning component is provided at the top of the right support block. A support column is fixedly connected to the bottom of the support block. A slide plate is fixedly connected to the bottom of the support column. Rotating shafts are fixedly connected to both the front and rear sides of the slide plate. Rollers are rotatably connected to the outside of the rotating shafts. Slide grooves are opened on both the left and right sides of the top of the support platform. The outer wall of the slide plate is slidably connected to the inner wall of the slide groove. Slide tracks are opened on both the left and right sides of the top of the support platform. The outer wall of the roller is slidably connected to the inner wall of the slide track. A local control box is provided at the bottom of the support platform.

[0006] Preferably, the cleaning component includes a fan, the left side of which is fixedly connected to the right side of the support block, the fan input end is fixedly connected to an air inlet pipe, the fan output end is fixedly connected to an air outlet pipe, the air outlet pipe output end is fixedly connected to a jet nozzle, and the top of the support block is fixedly connected to a housing.

[0007] Preferably, a motor is fixedly connected inside the housing, a disk is fixedly connected to the drive end of the motor, a protruding rod is fixedly connected to the top of the disk, a transmission plate is rotatably connected to the outside of the protruding rod, a concave slider is rotatably connected to the rear end of the transmission plate, and a vertical rod is fixedly connected to the top of the concave slider.

[0008] Preferably, a fixing rod is fixedly connected to the top of the housing, a rotating plate is rotatably connected to the outside of the fixing rod, the rear side of the rotating plate is fixedly connected to the front side of the air outlet pipe, and the outer wall of the vertical rod is slidably connected to the inner wall of the rotating plate.

[0009] Preferably, the inner wall of the bottom of the housing is fixedly connected to an I-shaped plate, and the inner wall of the concave slider is slidably connected to the outer wall of the I-shaped plate.

[0010] Preferably, a guide hole is provided at the top of the housing, and the outer wall of the vertical rod is slidably connected to the inner wall of the guide hole.

[0011] This utility model has the following beneficial effects:

[0012] (1) The eye valve replaces the louvered valve, avoiding the problem of difficulty in installing and removing blind plates due to the small gap between the two flanges. Through the cooperation of the sliding groove and the sliding plate on the top of the support platform, and the cooperation of the sliding track and the roller, when the eye valve is installed or operated during maintenance, the valve plate slides on the inner wall of the eye valve, the roller rolls along the sliding track, and the sliding plate slides in the sliding groove, which transforms the traditional sliding friction into rolling friction, greatly reducing the resistance of the valve plate movement, providing precise guidance for the valve plate, avoiding repeated adjustments due to inaccurate positioning during installation, making the eye valve installation more convenient and quick. In addition, the local control box set on the ground of the support platform can remotely operate the valve plate to loosen, clamp, open and close the valve. The operator does not need to approach the valve, effectively avoiding the danger of poisoning caused by CO leakage, reducing the risk of falling from heights, improving installation efficiency and ensuring the safety of the operators.

[0013] (2) Air is drawn in from the air inlet pipe by a blower and the airflow is sprayed out through the air outlet pipe and the jet nozzle to clean the valve plate. The motor drives the disc to rotate, and the protruding rod on the disc drives the transmission plate to move. The transmission plate then swings around the fixed rod through the concave slider and the vertical rod, which drives the air outlet pipe to swing, thereby realizing the continuous change of the jet nozzle direction. During this process, the airflow can be evenly sprayed to all parts of the valve plate, effectively removing the dust and impurities attached to the valve plate and avoiding the accumulation of impurities that affect the sealing performance and normal opening and closing of the valve.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, a precision-positioning eye valve includes a support platform 1 and a pipeline 2. An eye valve 3 is installed inside the pipeline 2, which is the installation location for conveying the medium. A valve plate 4 is slidably connected to the inner wall of the eye valve 3. As the core control component, the eye valve 3's inner wall is slidably connected to the valve plate 4. The opening and closing of the valve is achieved by the sliding of the valve plate 4, controlling the flow of the medium within the pipeline 2. A local control box is located at the bottom of the support platform 1, which can control the valve plate 4 to loosen, clamp, open, and close, eliminating the need to be near the valve and avoiding the risk of CO spillage and poisoning. Support blocks 5 are fixedly connected to both sides of the valve plate 4, providing additional support and connection points to keep the valve plate 4 stable during sliding, preventing displacement or jamming due to uneven force, and ensuring the eye valve 3's control over the medium flow. To ensure accuracy and reliability, a cleaning component is installed at the top of the right support block 5. The bottom of the support block 5 is fixedly connected to the support column 6, and the bottom of the support column 6 is fixedly connected to the slide plate 7, which transfers the weight of the valve plate 4 downwards. Slide grooves 10 are opened on both the left and right sides of the top of the support platform 1. The outer wall of the slide plate 7 is slidably connected to the inner wall of the slide groove 10. The slide groove 10 cooperates with the slide plate 7 to restrict the lateral movement of the slide plate 7 and ensure that the valve plate 4 slides stably in the horizontal direction. Rotating shafts 8 are fixedly connected to the front and rear sides of the slide plate 7. Rollers 9 are rotatably connected to the outside of the rotating shafts 8. The rotating shafts 8 provide rotational support for the rollers 9. Slide tracks 11 are opened on both the left and right sides of the top of the support platform 1. The outer wall of the rollers 9 is slidably connected to the inner wall of the slide tracks 11. The slide tracks 11 cooperate with the rollers 9 to reduce the frictional resistance when the valve plate 4 slides, and at the same time provide guidance for the movement of the valve plate 4, making the installation and operation of the eye valve 3 more convenient and stable.

[0021] like Figure 1 , 2As shown in Figure 4, the cleaning component includes a blower 12. The left side of the blower 12 is fixedly connected to the right side of the support block 5. The input end of the blower 12 is fixedly connected to the air inlet pipe, and the output end of the blower 12 is fixedly connected to the air outlet pipe 13. The output end of the air outlet pipe 13 is fixedly connected to the jet nozzle. The blower 12 is the core power source of the cleaning component. It draws in air through the air inlet pipe, compresses it, and then ejects a high-speed airflow from the air outlet pipe 13 and the jet nozzle. The airflow generated by the blower 12 can sweep the surface of the valve plate 4, removing the attached dust and impurities. The top of the support block 5 is fixedly connected to the housing 14. The inside of the housing 14 is fixedly connected to the motor 15. The drive end of the motor 15 is fixedly connected to the disc 16. The housing 14 provides installation space and protection for the motor 15, disc 16, and other components of the cleaning component. The motor 15 is the driving device of the cleaning component. It drives the disc 16 to rotate, providing power for the entire cleaning action. The top of the disc 16 is fixedly connected to the protruding rod 17. The outside of the protruding rod 17 is rotatably connected to the transmission plate 18. The rear end of the transmission plate 18 is rotatably connected to the concave slider 19. The disc 16 is in Driven by the motor 15, the disc 16 rotates, and its protruding rod 17 cooperates with the transmission plate 18 to convert the circular motion of the disc 16 into the reciprocating movement of the concave slider 19. The inner wall of the bottom of the housing 14 is fixedly connected to the I-shaped plate 20, and the inner wall of the concave slider 19 is slidably connected to the outer wall of the I-shaped plate 20. The I-shaped plate 20 provides a sliding track for the concave slider 19. The top of the concave slider 19 is fixedly connected to the vertical rod 21, and the top of the housing 14 is fixedly connected to the fixed rod 22. The fixed rod 22 is rotatably connected to the rotating plate 23. The rotating plate 23 is provided with a rotation support point. The rear side of the rotating plate 23 is fixedly connected to the front side of the air outlet pipe 13. The outer wall of the vertical rod 21 is slidably connected to the inner wall of the rotating plate 23. The concave slider 19 slides along the I-shaped plate 20 under the drive of the transmission plate 18, and drives the rotating plate 23 to swing through the vertical rod 21. A guide sliding hole 24 is opened at the top of the housing 14. The outer wall of the vertical rod 21 is slidably connected to the inner wall of the guide sliding hole 24. The guide sliding hole 24 provides sliding guidance for the vertical rod 21, ensuring the accuracy of the movement of the vertical rod 21.

[0022] Working principle: When the eye valve 3 is installed or operated, the valve plate 4 slides on the inner wall of the eye valve 3, the roller 9 rolls along the slide rail 11, and the slide plate 7 slides in the slide groove 10. This not only reduces frictional resistance but also provides precise guidance and stable support for the valve plate 4, making the eye valve 3 easy to install and run smoothly. The fan 12 draws in air through the air inlet pipe and sprays air out through the air outlet pipe 13 and the jet nozzle. The motor 15 drives the disc 16 to rotate, and the protruding rod 17 on the disc 16 drives the transmission plate 18 to move. The transmission plate 18, through the concave slider 19 and the vertical rod 21, causes the rotating plate 23 to swing around the fixed rod 22. The rotating plate 23 is connected to the air outlet pipe 13, causing the air outlet pipe 13 to swing. During this process, the motor 15 continues to run, and the air outlet pipe 13 and the jet nozzle continuously change the jet direction, spraying the airflow evenly onto the valve plate 4, effectively removing dust and impurities attached to the valve plate 4, and ensuring the cleanliness and normal operation of the eye valve 3.
