A first through hole is formed in the inner wall of the fixed flange. Two fixing blocks are arranged on the outer wall of the flat valve body near the two fixed flanges. Sealing blocks are arranged between the outer walls of the two fixing blocks on opposite sides and the inner walls of the two fixed flanges on opposite sides. A movable flange is provided on the outer side of the fixed flange. A second through hole is formed in the inner wall of the movable flange, and a fastening bolt is installed inside the second through hole. An outer connecting pipe is fixedly connected to the outer wall of the movable flange.

[0006] Furthermore, the first through holes are distributed at equal angles along the axial centerline of the fixed flange, and the fastening bolts are connected to the fixed flange through the first through holes, which facilitates the connection between the fixed flange and the movable flange.

[0007] Furthermore, the inner wall of the fixing block is provided with several threaded holes at equal angles, and the threaded holes cooperate with the fastening bolts, which facilitates the fastening of the fastening bolts.

[0008] Furthermore, the diameter of the sealing block is larger than the diameter of the fastening bolt, and the sealing block is an elastic rubber structure, which facilitates the sealing of the fastening bolt.

[0009] Furthermore, the second through holes are distributed at equal angles along the axial centerline of the movable flange, and the second through holes cooperate with the first through holes, which facilitates the installation of the movable flange.

[0010] Furthermore, a pad is provided between the inner end of the fastening bolt and the outer wall of the movable flange, which helps to improve the tightness after connection.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] (1) By setting up a flat valve body, a fixed flange, a first through hole, a fixed block, a sealing block, a movable flange, a second through hole, an external pipe and fastening bolts, the function of easy installation is realized, the problem of complicated installation operation is solved, and it is also conducive to sealing work after installation, which improves the sealing effect and solves the problem of leakage caused by poor sealing effect.
