The invention discloses a flexible intercepting device. The flexible intercepting device comprises an elastic sleeve and a housing, wherein the elastic sleeve is provided with a circulating channel, and the housing is arranged outside the elastic sleeve. The two ends of the elastic sleeve are detachably connected with the two ends of the housing in a sealed mode correspondingly, and in addition, agas cavity is formed between the inner wall of the housing and the outer wall of the elastic sleeve. The gas cavity is provided with air holes. When pressurized gas fills the gas cavity, the elasticsleeve deforms, and the section area of the circulating channel becomes smaller, wherein a lining protrusion is arranged on the inner wall of the elastic sleeve, and at least part of the lining protrusion is located in the stop position after the elastic sleeve deforms. The flexible intercepting device has the advantages of safety, reliability and good sealing effect.
本发明公开了一种柔性截流装置，包括：弹性套筒，具有流通通道；外罩，其设于所述弹性套筒外，所述弹性套筒的两端与所述外罩的两端可拆卸的密封连接，且所述外罩内壁与所述弹性套筒外壁之间形成气腔，所述气腔具有气孔，当所述气腔冲入有压气体时，所述弹性套筒变形，所述流通通道的截面积变小；其中，所述弹性套筒的内壁设有一内衬凸起，所述内衬凸起至少部分位于所述弹性套筒变形后的截止位置。本发明具有安全可靠、密封效果好的优点。
