[0003] Currently, common dispensing valves consist of a straight channel, an oblique channel connected to the sidewall of the straight channel at its upper end, and a baffle. When the baffle blocks the oblique channel, material is discharged from the straight channel; when the baffle blocks the straight channel, material is discharged from the oblique channel. Dispensing is manually controlled, which is labor-intensive. Therefore, conventional dispensing systems use electric baffles.

[0026] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0027] like Figure 1-Figure 7 As shown, the dispensing valve according to the embodiment of the present application includes:

[0028] The pipeline assembly 100 includes a three-way pipeline 110, on which an inlet valve port 120, a first outlet port 130, and a second outlet port 140 are respectively formed. A partition port 150 is provided between the inlet valve port 120, the first outlet port 130, and the second outlet port 140.

[0029] The split plate assembly 200 includes a driving member 210, a rotating shaft 220, a partition 230, an end seal 240, a pipe wall sealing plate 250 and a rotating indicator 260. The driving member 210 is fixedly connected to the outer wall of the three-way pipe 110, one end of the rotating shaft 220 is fixedly connected to the output end of the driving member 210, and the other end of the rotating shaft 220 passes through the pipe wall of the three-way pipe 110 and is rotatably connected to the inside of the three-way pipe 110. The partition 230 is fixedly connected to the rotating shaft 220. The partition 230 is located at the partition opening 150. The end seal 240 is fixedly connected to the end of the partition 230. The pipe wall sealing plate 250 is arranged at the partition opening 150. The pipe wall sealing plate 250 is used to seal the surrounding side of the partition 230. The rotating indicator 260 is fixedly connected to the rotating shaft 220, and the rotating indicator 260 is located on the outer wall of the three-way pipe 110. When in use, start the driving member 210, drive the rotating shaft 220 to rotate, and then drive the partition 230 to rotate, so that the partition 230 blocks the partition port 150, so that the material enters from the inlet valve port 120 and flows out from the first outlet port 130 or the second outlet port 140. When diverting, the partition 230 is placed on the pipe wall sealing plate 250, and the pipe wall sealing plate 250 seals the side wall and one side of the end of the partition 230. The end seal 240 is used to seal the end of the partition 230, so that when dividing the material, the partition 230 is sealed in place to prevent the occurrence of material cross-contamination, which solves the problem in the prior art that the electric baffle is not sealed in place, the valve is not closed tightly, resulting in material cross-contamination and poor sealing.

[0030] like Figure 3 As shown, a sealing sleeve 270 is fixedly sleeved between the rotating shaft 220 and the pipe wall of the three-way pipe 110. The sealing sleeve 270 is used to seal the gap between the rotating shaft 220 and the pipe wall of the three-way pipe 110.

[0031] like Figure 4 As shown, the drive member 210 includes a telescopic cylinder 211, a crank 212, and a drive shaft 213. The output end of the telescopic cylinder 211 is fixedly connected to a connecting block 214. One end of the crank 212 is hinged to the connecting block 214, and the other end of the crank 212 is fixedly connected to the drive shaft 213, which is fixedly connected to the rotating shaft 220. When the telescopic cylinder 211 is activated, the connecting block 214 moves, which in turn causes the crank 212 to swing, thereby rotating the drive shaft 213, which in turn causes the rotating shaft 220 to rotate, causing the partition 230 to swing, thereby separating the pipe openings. The outer wall of the tee pipe 110 is fixedly connected to a mounting plate 160, on which the telescopic cylinder 211 is mounted. The mounting plate 160 is used to securely mount the telescopic cylinder 211.

[0032] like Figure 5As shown, the end seal 240 includes a connecting rubber plate 241 and a flexible flocculent sealing strip 242. The connecting rubber plate 241 is fixedly connected to the end of the partition 230 by fixing bolts, and the flexible flocculent sealing strip 242 is fixedly connected to the connecting rubber plate 241. The flexible flocculent sealing strip 242 is flexible and deformable. When the flexible flocculent sealing strip 242 contacts the wall of the three-way pipe 110, it deforms and adheres to the wall of the three-way pipe 110, thereby forming a seal.

[0033] like Figure 6 As shown, the pipe wall sealing plate 250 includes a lap seal strip 251 and a sidewall seal strip 252. The lap seal strip 251 and the sidewall seal strip 252 are symmetrically connected at the partition opening 150. The end of the partition 230 rests on the lap seal strip 251, and the side wall of the partition 230 rests on the sidewall seal strip 252. The lap seal strip 251 allows the end of the partition 230 to rest on it, thereby forming a certain seal. At the same time, the side wall of the partition 230 rests on the sidewall seal strip 252, thereby forming a sealed structure between the partition 230 and the pipe wall of the tee pipe 110. A sealing block 253 is fixedly connected below the rotating shaft 220. The sealing block 253 is used to seal the gap between the bottom of the rotating shaft 220 and the pipe wall of the tee pipe 110.

[0034] like Figure 7 As shown, the rotation indicator 260 includes a rotation pointer 261 and a rotation indicator plate 262. One end of the rotation pointer 261 is fixedly connected to the rotation shaft 220, and the rotation indicator plate 262 is fixedly connected to the outer tube wall of the three-way pipe 110. The tip of the rotation pointer 261 is attached to the rotation indicator plate 262. The rotation indicator plate 262 is fixedly connected to the two sides of the rotation indicator plate 263. When the rotation shaft 220 rotates, the rotation pointer 261 is driven to rotate. When the rotation pointer 261 is on the side wall of the block 263, it indicates that the partition 230 has sealed the first outlet 130 or the second outlet 140, which is convenient for personnel to observe and divide the materials. The rotation indicator plate 262 is provided with a rotation angle indicator line 264. The rotation angle indicator line 264 can be used to understand the orientation of the partition 230 in the three-way pipe 110, making it easier to determine the separation.

[0035] In summary, the working principle of the material distribution valve of the embodiment of the present invention is as follows: when in use, the driving member 210 is started to drive the rotating shaft 220 to rotate, and then the partition 230 is driven to rotate, so that the partition 230 blocks the partition port 150, so that the material enters from the inlet valve port 120 and flows out from the first outlet port 130 or the second outlet port 140. When diverting, the partition 230 is placed on the pipe wall sealing plate 250, and the pipe wall sealing plate 250 seals the side wall and one side of the end of the partition 230. The end seal 240 is used to seal the end of the partition 230, so that when dividing the material, the partition 230 is sealed in place to prevent the occurrence of material cross-contamination, which solves the problem in the prior art that the electric baffle is not sealed in place, the valve is not closed tightly, resulting in material cross-contamination, and poor sealing.

[0036] The above are merely examples of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included within the scope of protection of the present application. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
