[0019] The utility model is further described in detail below based on the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1-5 As shown, a vertical axially opened manual electric valve comprises a valve body 1, an air inlet bracket 4 is installed in the valve body 1, a motor 2 is arranged on the air inlet bracket 4 through a motor mounting plate 3, the motor 2 is connected to a moving plate 9 through a shaft 5, the middle and upper part of the shaft 5 is connected to the air inlet bracket 4 through a first bearing 6, and the top of the shaft 5 is connected to a static plate 11 through a second bearing 7, two proximity switches 8 are arranged on the air inlet bracket 4, a first collision block 23 is arranged on the moving plate 9, and the proximity switch 8 cooperates with the first collision block 23; ventilation holes are provided on the moving plate 9 and the static plate 11, and the size and shape of the ventilation holes are the same;

[0022] Start the motor 2 to drive the moving piece 9 so that the ventilation holes on the moving piece 9 overlap with the ventilation holes on the static piece 11. At this time, the first collision block 23 on the moving piece 9 stops above the proximity switch 8, and the motor 2 stops.

[0023] like Figure 5 As shown, the second collision block 24 is arranged on the moving plate 9, and the limiting block 22 is arranged on the valve body 1, and the second collision block 24 cooperates with the limiting block 22;

[0024] When the first collision block 23 stops above the proximity switch 8, the second collision block 24 collides with the limit block 22 to clamp the movable plate 9 and prevent it from being out of position.

[0025] like Figure 1 , 4 As shown, a handle rod 16 is provided on the side of the static piece 11, and the handle rod 16 is elastically connected to the handle cover 14 through a first spring 15, and the handle cover 14 is snap-fitted to the handle top cover 13; in an emergency, the handle cover 14 is moved to drive the static piece 11 to rotate so that its ventilation hole coincides with the ventilation hole of the moving piece 9.

[0026] like Figure 3 , 4 As shown in 7, the air inlet bracket 4 is provided with a sliding sleeve 18, the sliding sleeve 18 is connected to the sliding cylinder 19, a universal ball bearing 20 is provided in the sliding cylinder 19, the universal ball bearing 20 is slidably connected to the moving piece 9, and a second spring 21 is provided on the outer sleeve of the universal ball bearing 20;

[0027] When the valve is in a closed state and the universal ball bearing 20 fits in with the groove on the moving plate 9 , it indicates that the first collision block 23 is located above the proximity switch 8 .

[0028] like Figure 4 As shown, sealing rings 10 are provided at both upper and lower ends of the periphery of the static plate 11 , and a pressure ring 12 is provided between the static plate 11 and the valve body 1 .

[0029] like Figure 6 As shown, a plug 17 is provided on the valve body 1 .

[0030] The above valve is used in the following process: under normal circumstances, the motor 2 is started, the motor 2 rotates the movable plate 9, and when the first collision block 23 on the movable plate 9 moves from above the horizontal proximity switch 8 to above the vertical proximity switch 8, the proximity switch 8 sends a signal to stop the motor 2, and the motor 2 stops running. At this time, the second collision block 24 is located at the limit block 22, and the ventilation holes of the movable plate 9 and the static plate 11 overlap, and ventilation is performed; when the ventilation holes need to be closed, the motor 2 is started, the motor 2 rotates the movable plate 9, and when the first collision block 23 on the movable plate 9 moves from above the vertical proximity switch 8 to above the horizontal proximity switch 8, the proximity switch 8 sends a signal to stop the motor 2, and the motor 2 stops running. At this time, the ventilation holes on the movable plate 9 and the static plate 11 do not overlap, and the universal ball bearing 20 on the mounting bracket 4 overlaps with the corresponding groove on the movable plate 9, and the ventilation is closed;

[0031] In an emergency, when the motor 2 cannot be started, the static plate 11 is rotated by rotating the handle bar 16 on the static plate 11 so that the ventilation holes of the moving plate 9 and the static plate 11 overlap and ventilation is performed.
