On the basis of the technical scheme, the inner tube 21 is made of stainless steel, and the outer tube 22 and the sealing ring 23 are made of nylon.
On the basis of the above technical solution, the outer tube 22 is formed with a first rotation shaft 221 and a second rotation shaft 222, the first rotation shaft 221 and the second rotation shaft 222 are coaxial, the first rotation shaft 221 and the second rotation shaft 222 are respectively connected with the valve body 1 in a rotation manner, and the output shaft 31 of the driving device 3 is fixedly connected with the second rotation shaft 222.

Working principle:
when the valve is used as a material line valve, the position of the rotary pipe 2 in the initial state is shown in fig. 3 and 5, and the rotary pipe 2 is communicated with the material inlet pipe 4 and the material outlet pipe 5 coaxial with the material inlet pipe. At this point feed enters the rotary tube 2 from the feed tube 4 and exits the valve from the coaxial discharge tube 5 before continuing to move in the feed line feed tube.
When the valve needs to feed, the feed in the feed line stops moving. The driving device 3 drives the rotary pipe 2 to do circular motion by taking the first rotary shaft 221 and the second rotary shaft 222 as shafts until the rotary pipe 2 communicates the feeding pipe 4 with the discharging pipe 5 which is not coaxial with the feeding pipe, as shown in fig. 6. Thereafter, the feed in the stockline starts to move, and the feed is discharged from the inclined downward discharge pipe 5 into the trough of the livestock.
After the blanking is finished, the feed in the feed line stops moving, and the driving device 3 drives the rotary pipe 2 to rotate until the feed line starts rotating. Thereafter, the feed in the stockline may start to move.
It should be noted that the rotating tube 2 may be an integrally formed metal tube or a non-metal tube. When the rotation pipe 2 is an integrally formed metal pipe, the life is long, but the manufacturing cost is high. When the rotation tube 2 is made of an integrally formed nonmetallic tube (such as plastic, nylon and other materials), the manufacturing cost is lower, but compared with a metallic tube, the rotation tube is not wear-resistant, and the service life is shorter. Therefore, it is preferable that the inner tube 21 is made of a metal material and requires a processing treatment to reduce friction during material transfer; the outer tube 22 has a complex shape and structure and is made of metal, so that the outer tube is made of nonmetal such as nylon, and the manufacturing cost is lower than that of metal, so that the cost is saved. The seal ring 23 is removable to facilitate replacement of only the seal ring 23 when the seal ring 23 wears, thereby saving cost.
The present utility model has been described above by way of example, but the present utility model is not limited to the above-described embodiments, and any modifications or variations based on the present utility model fall within the scope of the present utility model.
