The gate pipe 1 is inserted with a driving shaft 2, and the outer side of the driving shaft 2 is sleeved with a gate assembly 3, so that the gate assembly 3 is positioned in the gate pipe 1. Both ends of the driving shaft 2 are rotatably connected with a rotating shaft seat 21, and one end of the driving shaft 2 is provided with a driving mechanism 4 which is responsible for realizing the opening and closing operation of the gate assembly 3.

Referring to fig. 2 to 5, in order to improve sealing performance, two first sealing stoppers 15 are fixedly connected to the inner side of the gate tube 1, and the two first sealing stoppers 15 are centrally symmetrical around the axis of the through hole 14. The gate assembly 3 comprises a sleeve 31, and a gate plate 32 is symmetrically and fixedly connected to the outer side of the sleeve 31. In order to further improve the sealing property, the second sealing stopper 321 is fixedly connected to the outer side of the shutter plate 32, and when the shutter assembly 3 is closed, the second sealing stopper 321 is tightly attached to the first sealing stopper 15.

Referring to fig. 5, in order to enhance structural stability, threaded holes 311 are symmetrically formed through the outer side of the sleeve 31, and reinforcing bars 312 are symmetrically and fixedly connected to the outer side of the sleeve 31.
