Zusammenfassung:PROBLEM TO BE SOLVED: To provide a rotary valve that allows particulate bodies to be extracted from an inclined transportation container without forming an underground pit by adopting a structure which does not require piping below a casing.SOLUTION: A rotary valve 1 is formed by supporting a rotor 4 comprising a plurality of radiating blades 41 on a periphery of a shaft thereof inside a tubular casing 2, an opening part of an upper surface of which is blocked with a cover 3, so that the rotor can be turned with a shaft 40 set in a vertical direction. In the cover 3, at different angular positions around the shaft 40 are provided a receiving port 33 for particular bodies and an introducing port 34 for air for pneumatic transportation. In a peripheral wall part 21 of the casing 2, at an angular position identical to the angular position of the introducing port 34 is provided an exhaust port 26 for particular bodies.SELECTED DRAWING: Figure 3 【課題】ケーシングの下方に配管を必要としない構造を採用することにより、地下ピットを形成することなく、傾けた輸送用コンテナからの粉粒体の抜出が可能なロータリーバルブを提供する。【解決手段】ロータリーバルブ1は、上面の開口部がカバー3により塞がれた筒状のケーシング2の内部に、軸周に放射状をなす複数の羽根板41を備えたローター4が軸40を鉛直方向にして回動可能に支持されてなるもので、カバー3には、軸40の周囲の異なる角度位置に、粉粒体の受入口33と圧送用空気の導入口34とが設けられ、ケーシング2の周壁部21には、導入口34の角度位置と同じ角度位置に、粉粒体の排出口26が設けられている。【選択図】図3
