Zusammenfassung:	To provide a segment ball valve that is excellent in pressure controllability and less likely to clog, and that is suitable for loading and discharging slurry under pressure.SOLUTION: In a segment ball valve, a valve body having a V-shaped cut is rotatably provided via a valve body shaft part in a casing having a flow path communicating with an inlet and outlet. By providing a solvent introduction flow path for removing deposits that communicates with the outside of the casing, in a clearance part between an inner peripheral surface of the casing and an external surface of the valve body with respect to the flow path of the casing, the segment ball valve with a cleaning and discharging function cleans and discharges deposits in the clearance part.SELECTED DRAWING: Figure 1 【課題】圧力制御性に優れる上に閉塞を起こしにくいセグメントボールバルブに関するものであり、圧力下でのスラリーの搬入・排出に適したセグメントボールバルブを提供する。【解決手段】流出入口を連通する流路を有するケーシング内にＶ字型切込みを有する弁体を弁体軸部を介して回転自在に設けたセグメントボールバルブであって、該ケーシングの流路に対して該ケーシングの内周面と該弁体の外表面との間のクリアランス部にケーシング外部と連通する堆積物除去のための溶媒導入流路を設けることにより、該クリアランス部の堆積物を洗浄排出する洗浄排出機能付きセグメントボールバルブ。【選択図】図１
