In the conventional rotary valve shown in FIGS. 3 and 4, the seal vane member 4 is provided by the support member 11 provided at the lower portion thereof, and the side seal member 6 is provided at the lower portion thereof. The support ring 18 is pressed against the inner surface of the casing 3 and is in close contact with the inner surface of the casing 3.
In order to fill in the gaps between the peripheral vane walls of the seal vane material 4 and the side seal material 6,
A resistance force is generated, and eventually, the support forces of the support member 11 and the support ring 18 cannot overcome the resistance force, whereby the seal vane member 4 and the side seal member 6 lose the support force and the inner surface of the casing 3 is lost. Cannot be pressed against. As a result, a large gap is created between the seal vane material 4 and the side seal material 6 and the inner surface of the casing 3, which is a factor that makes it impossible to maintain the airtightness between the pockets. The present invention has been proposed to solve the above conventional problems, and an object of the present invention is to provide a rotary valve capable of maintaining airtightness between pockets for a long period of time.

To explain the operation, the solid raw material charged from the supply port 1 is passed through the opening 20 of the cylindrical sealing material 12 and the pocket 1 between the partition plates 5 of the rotating shaft 7 which rotates.
After being supplied to the nozzle 9, it is rotated by 180 °, and is discharged from the discharge port 2 through the opening 21 of the tubular sealing material 12. In this case, in order to maintain the airtightness of the wear resistant member 27 on the outer peripheral surface of the partition plate 5 and the inner peripheral surface of the tubular sealing material 12, the bolt 14 is rotated to push the push plate 13 inward, and the push plate 13 is pushed inward. Presses the outer surface of the tubular seal material 12, and the cutout portion of the tubular seal material 12,
That is, the packing 17 is contracted to reduce the inner diameter of the sealing material 12 and maintain airtightness with the partition plate 5. On the contrary, when the bolt 14 is rotated in the opposite direction to the above, the pressing force of the pressing plate 13 against the tubular sealing material 12 becomes small, so that the elastic repulsive force of the tubular sealing material 12 causes the sealing material 12 to rotate. The inner diameter of is enlarged.

As described in detail above, according to the present invention, it is not necessary to provide a groove on the outer peripheral surface of the partition plate of the rotor to attach a seal vane material or a side seal material as in the prior art. Since there is nothing at all, it is possible to eliminate the drawbacks such as the fact that the raw material is clogged in the gap between the groove and the sealing material to generate resistance, and the airtightness cannot be maintained so that the pocket cannot be airtightly maintained. Further, the gap between the outer peripheral surface of the partition plate of the rotor and the inner peripheral surface of the tubular seal material can be easily adjusted by pressing the inner diameter of the tubular seal material with a pressing plate, and Since the outer surface is a flat surface, the airtightness between the pockets can be stably maintained for a long period of time, and the number of maintenances is significantly reduced as compared with the conventional rotary valve, and the maintenance cost can be reduced.
