Description

Technical Field

[0001] This utility model relates to material valves, particularly stem-type side-opening rotary valves. Background Technology

[0002] The material valve drives the impeller to rotate via a rotating shaft, enabling precise metering and feeding of various materials such as fruits, grains, and medicines. It is widely applicable to batching scenarios in multiple industries.

[0003] In scenarios involving switching between multiple ingredient batches, the material valves must be thoroughly cleaned to avoid cross-contamination caused by residues from previous batches. The core cleaning targets are the impeller and the valve body cavity, as these areas are prone to accumulating material debris, which directly affects the purity of subsequent batches.

[0004] Conventional cleaning methods require completely disassembling the impeller and valve body, and carrying out the cleaning operation by detaching them as a whole. Although this method can ensure the cleaning effect, the disassembly process is cumbersome and requires a lot of time. After cleaning, the reassembly requires precise alignment of the installation position, which further increases the operation time. Overall efficiency is low and it is difficult to meet the needs of high-efficiency production.

[0005] In summary, how to clean the valve body cavity and impeller, and facilitate rapid assembly after cleaning, has become an urgent problem for researchers in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to conveniently clean the valve body cavity and impeller, and how to achieve rapid assembly after cleaning.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a stem-type side-opening rotary valve, including a valve body with an inlet and an outlet formed vertically. A left end cover is detachably connected to the left side of the valve body, and a right end cover is connected to the right side of the valve body. A rotating shaft is disposed within the valve body. The left end of the rotating shaft is connected to the left end cover via a bearing assembly, and the right end of the rotating shaft passes through the right end cover and is connected to the motor output end on the right side of the valve body. An impeller is fixed on the rotating shaft. A sliding seat is fixedly disposed on the front side of the valve body, and a horizontal valve stem passes through the sliding seat. A hinge assembly is disposed on the left end of the valve stem, and the hinge assembly is connected to the left end cover. After the rotating shaft is pulled away from the valve body along the length of the valve stem, the hinge assembly is used to rotate the rotating shaft along the horizontal plane.

[0008] Furthermore, the valve stems are configured as two parallel stems running vertically.

[0009] Furthermore, the hinge assembly includes: a connecting rod seat disposed at the left end of the valve stem, with connecting rods disposed above and below the connecting rod seat, and a fixing seat disposed on the left end cover, the fixing seat being hinged to the end of the connecting rod.

[0010] Furthermore, the fixing base has an L-shaped structure.

[0011] Furthermore, the left end cover is provided with a handle to facilitate pulling and rotating the left end cover.

[0012] Furthermore, a stop is provided at the right end of the valve stem.

[0013] The beneficial effects of this utility model are as follows: This utility model is a stem-type side-opening rotary valve. The left end cover, along with the rotating shaft, is pulled out of the valve body to the left along the length of the valve stem. Then, the hinge assembly is used to rotate the rotating shaft and the left end cover along the horizontal plane. That is, after the rotating shaft and the left end cover are pulled out of the valve body, they are rotated 90° clockwise. At this time, the left end cover and the rotating shaft are in a vertical state. At this time, a large space is formed between the rotating shaft and the valve body. Personnel can then enter this space to thoroughly clean the inner wall of the valve body and the impeller on the rotating shaft. After cleaning, the left end cover and the rotating shaft can be quickly installed. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] See Figure 1-3This embodiment is a stem-type side-opening rotary valve, including a valve body 1. The valve body 1 is vertically connected and has an inlet 11 and an outlet 12. Material enters through the inlet 11, and the rotation of the rotating shaft 3 and impeller 4 driven by the motor 2 discharges the material from the outlet 12 in a certain metered manner. A left end cover 5 is detachably connected to the left side of the valve body 1. The left end cover 5 is detachably connected to the left side shell of the valve body 1 by screws 51. A right end cover 6 is connected to the right side of the valve body 1. The valve body 1 contains... A rotating shaft 3 is provided. The left end of the rotating shaft 3 is connected to the left end cover 5 through a bearing assembly. The left end of the rotating shaft 3 and the left end cover 5 are axially limited relative to the left end cover 5 by a component such as a snap ring. The right end of the rotating shaft 3 passes through the right end cover 6 and is connected to the output end of the motor 2 on the right side of the valve body 1. The right side of the rotating shaft 3 is also connected to the right end cover 6 through a bearing. The right end cover 6 is not axially limited relative to the right end of the rotating shaft 3. An impeller 4 is fixed on the rotating shaft 3. A sliding seat 7 is fixedly installed on the front side of the valve body 1. A horizontal valve stem 8 passes through the sliding seat 7. A hinge assembly 9 is provided at the left end of the valve stem 8. The hinge assembly 9 is connected to the left end cover 5. After disassembling the left end cover 5 from the left side of the valve body 1, see... Figure 4 Along the length of the valve stem 8, pull the left end cap 5, along with the rotating shaft 3, to the left away from the valve body 8. (See below) Figure 5 Subsequently, the hinge assembly 9 is used to rotate the rotating shaft 3 and the left end cover 5 along the horizontal plane, that is, after the rotating shaft 3 and the left end cover 5 are pulled away from the valve body 1, they rotate 90° clockwise. At this time, the left end cover 5 and the rotating shaft 3 are in a vertical state, and a large space is formed between the rotating shaft 3 and the valve body 5. Personnel can then enter this space to thoroughly clean the inner wall of the valve body 1 and the impeller 4 on the rotating shaft 3. After cleaning, the left end cover 5 and the rotating shaft 3 can also be quickly installed. Compared with the method of cleaning the left end cover 5 horizontally away from the valve body 1, this solution can provide a larger cleaning space.

[0018] See Figure 1 In some possible embodiments, the valve stems 8 are configured as two parallel vertically. In this embodiment, in order to prevent the left end cover 5 from rotating during the movement of the valve stem 8 to the right, two valve stems 8 are provided. This arrangement can prevent the left end cover 5 from rotating during the movement to the left.

[0019] See Figure 1 , 4 In some possible embodiments, the hinge assembly 9 includes: a connecting rod seat 91 disposed at the left end of the valve stem 8, connecting rods 92 disposed above and below the connecting rod seat 91, a fixing seat 93 disposed on the left end cover 5, the fixing seat 93 being hinged to the end of the connecting rod 92, and the fixing seat 93 having an L-shaped structure.

[0020] In this embodiment, the left end of the valve stem 3 is fixedly mounted on the connecting rod seat 91, and the connecting rod 92 is fixed on the connecting rod seat 91. The connecting rod 92 is hinged to the fixed seat 93, and the fixed seat 93 is fixedly connected to the left end cover 5. In this way, after the rotating shaft 3 is pulled out of the valve body 1 laterally, the fixed seat 93 rotates relative to the connecting rod 92, and the left end cover 5 and the rotating shaft 3 can rotate 90° clockwise.

[0021] See Figure 1 In some possible embodiments, the left end cover 5 is provided with a handle 52 to facilitate the pulling and rotating of the left end cover 5; In this embodiment, the operator holds the handle 52 and can pull the left end cover 5 to the left and rotate the left end cover 5 clockwise.

[0022] See Figure 1 In some possible embodiments, a stop 81 is provided at the right end of the valve stem 8; In this embodiment, by setting a stop 81, the maximum distance the valve stem 8 can move to the left is limited, thus preventing the valve stem 8 from disengaging from the sliding seat 7.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
