2-4, the utility model provides an embodiment: a self-cleaning rotary valve structure suitable for high-viscosity materials, including a valve body 1, a first sealing cover 2 is rotatably connected inside the valve body 1, a second sealing cover 3 is rotatably connected inside the valve body 1, a plurality of hollow columns 7 symmetrical in upper and lower directions are fixedly connected to one side of the second sealing cover 3, a plurality of hollow columns 1 4 symmetrical in upper and lower directions are fixedly connected to one side of the first sealing cover 2, a rotating column 5 is rotatably connected inside the hollow column 1 4, an outer wall of the rotating column 5 is rotatably connected inside the hollow column 2 7, the hollow column 1 4 is connected to the hollow column 2 7 through the rotating column 5, and one end of the rotating column 5 is fixedly connected to the first connecting A connecting column 6, one end of which is a hollow column 2 7, is fixedly connected to a second connecting column 8, a fixing frame 9 is fixedly connected to the outer wall of the valve body 1, an electric push rod 10 is fixedly connected inside the fixing frame 9, and a connecting frame 11 is fixedly connected to the output end of the electric push rod 10, and a connecting component is arranged on the inner wall of the connecting frame 11, and the connecting component includes a fixing block 12, one side of the fixing block 12 is fixedly connected to the inner wall of the connecting frame 11, a slot 13 is provided inside the fixing block 12, the first connecting column 6 and the second connecting column 8 are both rotatably connected inside the slot 13, a slide slot 14 is provided inside the fixing frame 9, and the outer wall of the connecting frame 11 is slidably connected inside the slide slot 14.

Specifically, when the rotary valve is used, the operation starts from the output end of the electric push rod 10, which drives the connecting frame 11 to move. During the movement of the connecting frame 11, its outer wall slides smoothly inside the slide slot 14, and then the connecting frame 11 pushes the fixed block 12 fixed inside to move in coordination. The fixed block 12 effectively pushes the second connecting column 8 and the first connecting column 6 to start rotating through the action of the internal slot 13. During the rotation process, the first connecting column 6 drives the rotating column 5 fixed at one end to rotate inside the hollow column 14. At the same time, under the influence of the force, the hollow column 14 drives the first sealing cover 2 fixed at one side to rotate inside the valve body 1. At the same time, the second connecting column 8 also pulls the hollow column 27 fixed at one end to rotate. At this time, the hollow column 27 acts on the second sealing cover 3 fixed at one side to rotate accordingly, thereby achieving the effect of controlling the first sealing cover 2 and the second sealing cover 3 to open or close for sealing.

1 and 6 , a threaded column 15 is provided on one side of the valve body 1, a connecting ring 16 is threadedly connected to the outer wall of the threaded column 15, a sliding column 17 is slidably connected inside the threaded column 15, a support rod 18 is rotatably connected inside the sliding column 17, a support column 19 is slidably connected inside the sliding column 17, and the outer wall of the support column 19 is slidably connected inside the threaded column 15.

Specifically, when the valve body 1 needs to be installed, the threaded column 15 is cleverly passed through the side wall of the valve body 1 and the side wall of the object to be fixed, and then the sliding column 17 fixedly connected on one side is pulled by the retaining ring 21 to cause movement inside the threaded column 15. This action not only guides the rotating connection support rod 18 inside the sliding column 17 to rotate, but also allows the support rod 18 to extend toward the outside of the threaded column 15 through rotation, and accurately clamped behind the fixed object. Then, the connecting ring 16 is rotated, and the threaded connection between the connecting ring 16 and the threaded column 15 is used to achieve the connection The ring 16 is subjected to force on its outer wall and moves, and finally the connecting ring 16 is moved to the side wall of the valve body 1, and it is cleverly clamped tightly, thereby achieving the effect of quickly installing the rotary valve.

1 and 5 , a spring 20 is sleeved on the outer wall of the support column 19 , a retaining ring 21 is fixedly connected to one end of the sliding column 17 , one end of the spring 20 is fixedly connected to one end of the sliding column 17 , and the other end of the spring 20 is fixedly connected to the inside of the threaded column 15 .

Specifically, when the rotary valve needs to be disassembled, the slide column 17 is driven to move inside the threaded column 15 by pressing the retaining ring 21. At this time, the slide column 17 is forced to drive the spring 20 fixed at one end to contract. At the same time, the support rod 18 is retracted into the slide column 17 through the squeezing of the spring 20. Then the spring 20 unloads the force and rebounds, and the threaded column 15 is removed from the side wall of the valve body 1, thereby achieving the effect of quick disassembly.

Working principle: When using the rotary valve, the output end of the electric push rod 10 is first used to drive the connecting frame 11 to move. At this time, the outer wall of the connecting frame 11 is forced to slide inside the slide groove 14, and then the connecting frame 11 drives the internal fixed block 12 to move. At this time, the fixed block 12 pushes the second connecting column 8 and the first connecting column 6 to rotate through the internal slot 13. The first connecting column 6 drives the rotating column 5 fixed at one end to rotate inside the hollow column 4. Then, the hollow column 4 is forced to drive the first sealing cover 2 fixed at one side to rotate inside the valve body 1. At the same time, the second connecting column 8 drives the hollow column 2 7 fixed at one end to rotate. At this time, the hollow column 2 7 is forced to drive the second sealing cover 3 fixed at one side to rotate, thereby achieving a controllable first sealing cover. A sealing cover 2 and a second sealing cover 3 are opened and closed to achieve a sealing effect. When the valve body 1 needs to be installed on other objects, the threaded column 15 is first passed through the side wall of the valve body 1 and through the object to be fixed. Then, the sliding column 17 fixedly connected on one side is driven to move inside the threaded column 15 by pulling the retaining ring 21. At this time, the sliding column 17 is forced to drive the support rod 18 connected internally to rotate. The support rod 18 extends to the outside of the threaded column 15 through the rotation, so as to be stuck on the side wall of the fixed object. Then, the connecting ring 16 is twisted to rotate on the outer wall of the threaded column 15. Through the threaded connection between the connecting ring 16 and the threaded column 15, the connecting ring 16 is forced to move on the outer wall of the threaded column 15. At this time, the connecting ring 16 moves to the side wall of the valve body 1 and sticks it, thereby achieving the effect that the valve body 1 can be quickly installed.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
