Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a dust material valve with a buffer structure. Background Art

[0002] Dust material valve is a device specially used to control the flow of dust and granular materials. It is commonly used in various industrial occasions, such as food processing, pharmaceutical, chemical and mining industries. This type of valve can effectively isolate dust in the system, prevent leakage, keep the factory environment clean, and ensure the flow and control of materials.

[0003] However, butterfly valves are often used to control the flow of dust and particulate materials. Dust materials with excessively high flow rates may cause the rapid flow of materials to cause a greater impact on the valve during the transmission of dust materials. At the same time, when the valve is operated, the flow and discharge of materials may cause a large amount of dust to fly.

[0004] Therefore, it is necessary to provide a dust material valve with a buffer structure to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0009] Preferably, the valve body further comprises a butterfly plate and an electric actuator, the butterfly plate is rotatably connected to the interior of the valve body via a shaft column, and the output end of the electric actuator is drivingly connected to one of the shaft columns on the butterfly plate.

[0010] Preferably, the feed pipe includes a tube body, a first flange and a second flange, one end of the tube body is integrally formed with the first flange, and the other end of the tube body is integrally formed with the second flange, the first flange is fixed to the docking flange on the valve body by screws, and the transition part from the tube body to the first flange and the second flange is set as an inner opening, and a circle of the movable disk conflicts with the inner opening between the second flange and the tube body.

[0014] The beneficial effects of this application are:

[0015] By setting a buffer mechanism in the feed pipe, the impact force of dust materials on the valve can be effectively reduced, and the risk of mechanical wear and damage can be reduced. The existence of the buffer structure can effectively slow down the material flow rate and reduce the flying of dust during valve operation. The movable disc and spring system can buffer the impact when the dust material flows in, preventing the dust material from directly acting on the valve body and butterfly plate at an excessively high flow rate. In this way, the safety and reliability of the valve during operation are improved. Through the design of the conical structure and the movable disc, the dust material gradually slows down when passing through the valve, which helps to maintain a stable flow of the material and avoid operational problems caused by sudden changes in flow rate.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0031] See also Figure 1-4 , the embodiment provided by the utility model:

[0032] A dust material valve with a buffer structure includes a valve body 1, the valve body 1 includes a valve body 11 and a docking flange 12, and the docking flanges 12 are integrally formed on both sides of the valve body 11. The valve body 1 also includes a butterfly plate 13 and an electric actuator 14. The butterfly plate 13 is rotatably connected to the interior of the valve body 11 through a shaft column. The output end of the electric actuator 14 is transmission-connected to one of the shaft columns on the butterfly plate 13. The butterfly plate 13 is driven by the electric actuator 14 to rotate in the valve body 11 along the shaft column as the axis, and can open or close the valve body 11, so that dust materials can pass through the opening and closing of the valve, and select dust materials.

[0033] The docking flange 12 on one side of the valve body 11 is docked and installed with the feed pipe 2 by screws, and the docking flange 12 on the other side of the valve body 11 is docked and installed with the discharge pipe 3 by screws. The dust material enters the valve body 11 through the feed pipe 2. If the butterfly plate 13 in the valve body 11 is in the open state, the dust material enters the discharge pipe 3 through the valve body 11 and is discharged.

[0034] In order to prevent the dust material from flowing too fast and causing damage to the valve, a buffer mechanism 4 is installed inside the feed pipe 2. The buffer mechanism 4 includes a movable disk 41, a slide column 42, a spring 43, a support disk 45, a support rod 46 and a nut 47. The inner center of the movable disk 41 is fixedly connected to one end of the slide column 42, and a circle of the support disk 45 is fixedly connected to one end of the support rod 46. The other end of the support rod 46 is fixedly connected to the inner side wall of the feed pipe 2. A sliding hole is provided in the center of the side wall of the support disk 45. The side wall of the slide column 42 is slidably connected in the sliding hole. The other end of the slide column 42 is provided with a threaded groove. The inside of the nut 47 is threadedly connected to the side wall of the other end of the slide column 42. The spring 43 is sleeved on the side wall of the slide column 42. One end of the spring 43 contacts the support disk 45, and the other end contacts the inner side of the movable disk 41.

[0035] The principle is: when the dust material passes through one side of the feed pipe 2 and enters the inside of the feed pipe 2, the movable disc 41 is pushed by the dust material due to the elastic force of the spring 43, which compresses the spring 43 and separates the movable disc 41 from one side of the feed pipe 2.

[0036] Specifically, the feed pipe 2 includes a tube body 21, a first flange 22 and a second flange 24. One end of the tube body 21 is integrally formed with the first flange 22, and the other end of the tube body 21 is integrally formed with the second flange 24. The first flange 22 is fixed to the docking flange 12 on the valve body 11 by screws. The transition part from the tube body 21 to the first flange 22 and the second flange 24 is set as an inner opening 23, and a circle of the movable disk 41 conflicts with the inner opening 23 between the second flange 24 and the tube body 21.

[0037] The movable disc 41 is separated from the inner opening 23 between the second flange 24 and the tube body 21, allowing the dust material to enter the tube body 21 and finally be discharged into the valve body 11 through the first flange 22. In this process, the elastic force of the spring 43 is utilized to reduce the flow rate of the dust material passing through the feed pipe 2 under the reaction force of the elastic force of the spring 43 compressed by the movable disc 41, thereby effectively preventing the dust material with a large flow rate from exerting too much force on the butterfly plate 13 in the valve body 11, thereby damaging the valve, providing protection for the valve, and extending the service life of the valve.

[0038] Among them, the movable disk 41 is located on one side of the second flange 24 and has a conical structure, and a circle of the movable disk 41 is provided with a folded edge, so that when the dust material with a larger flow rate acts on the movable disk 41, the conical structure can provide a guiding effect on the dust material. While pushing the movable disk 41 to move backward, the dust material flows along the conical surface around the movable disk 41, flows from the pipe body 21 to the first flange 22, and finally the dust material with a slowed flow rate passes through the valve body 11 and is discharged from the discharge pipe 3.

[0039] Furthermore, a circle of the support plate 45 is respectively provided with guide holes 48, and a circle of the inner side of the movable plate 41 is respectively fixedly connected with guide rods 44 at equal angles. The guide rods 44 are slidably connected in the corresponding guide holes 48. The guide rods 44 slide in the guide holes 48 on the support plate 45, and the movable plate 41 moves along the axis of the tube body 21, preventing the support plate 45 from offsetting during the sliding process, and at the same time alleviating the force on the sliding column 42, thereby extending the service life of the buffer mechanism 4.

[0040] In order to further alleviate the impact of excessive flow rate on the valve body 11, a plurality of buffer plates 5 are rotatably connected inside the first flange 22. The plurality of buffer plates 5 are disc-shaped as a whole. The buffer plates 5 include fan blades 51 and a rotating shaft 52. The fan blades 51 are fixedly connected to the upper part on both sides. The rotating shaft 52 is rotatably connected in the axial hole opened on the inner wall of the first flange 22. When the dust material passes through the first flange 22, the airflow pushes the plurality of fan blades 51 to rotate along the rotating shaft 52, so that the dust material is discharged into the valve body 11 through the gaps between the opened fan blades 51, further slowing down the flow rate of the dust material.

[0041] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
