Example one
Referring to fig. 1-8, an embodiment of the present disclosure provides a flow stop device, including: outer barrel 1, drive assembly 2 and seal receptacle 3. Wherein, the outer cylinder body 1 is provided with a first opening 111 for externally connecting a water outlet pipeline at a first part 11, and is provided with a second opening 121 for intercepting flow at a second part 12; the outer cylinder 1 is also provided with a closure seal 14 at said second portion 12; the driving assembly 2 is fixed at a third part 13 of the outer cylinder 1 and is in sealing connection with the third part 13, and the third part 13 and the first part 11 are oppositely distributed on the outer cylinder 1; the sealing seat 3 is fixedly connected with the driving assembly 2, and the first part 11 is positioned between the second part 12 and the third part 13.

That is to say, the setting position of the sealing seat 3 is not limited in the embodiment of the present application, and the present invention is applicable as long as the driving assembly 2 can drive the sealing seat 3 to move so as to attach or detach the closure sealing member 14.
Further, in the four embodiments of the driving assembly 2, the connection between the upper region 231 and the lower region may be formed by connecting bolts 1 to form the second cover 23; the second cover 23 may be formed integrally. Meanwhile, in order to facilitate the connection between the driving assembly 2 and the outer cylinder 1, a cover connecting portion 2322 is further disposed at the lower region 232, the cover connecting portion 2322 is of a hollow cylindrical structure, the lower region 232 is hermetically connected (for example, bolted) with the third portion 13 of the outer cylinder 1 through the cover connecting portion 2322, and at this time, the other end of the connecting rod 25 sequentially penetrates through the internal space of the cover connecting portion 2322, the internal space of the outer cylinder 1, and the sealing seat 3 to be fixedly connected.
