Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 In order to achieve the above-mentioned purpose of quickly cutting off the fluid, the utility model provides the following technical solutions: a valve that can quickly cut off the fluid, including a valve body 1, a mounting frame 2 is fixedly connected to the outside of the valve body 1, a screw seat 3 is fixedly connected to the top of the mounting frame 2, a side frame 4 is fixedly connected to the top of the mounting frame 2, an accommodating chamber 5 is fixedly connected to the inner wall of the side frame 4, the valve body 1 is internally movably connected to a threaded valve stem 6 with one end passing through the mounting frame 2, the screw seat 3 and the accommodating chamber 5 in sequence and extending to the inside of the accommodating chamber 5, the top end of the threaded valve stem 6 is fixedly connected to a telescopic shaft 7, the top end of the telescopic shaft 7 is fixedly connected to a clamping sleeve 8 with one end extending to the outside of the accommodating chamber 5, and the outer side of the clamping sleeve 8 is fixedly connected to a driven cone wheel 9.

[0024] In the above embodiment, the valve body 1 is of the prior art, in which a valve core is provided, and the valve core is connected to the threaded valve stem 6 to perform fluid cut-off and blocking processing.

[0025] It should also be noted that in this embodiment, a threaded groove is provided on the inner wall of the threaded seat 3, which is matched with the threaded strip on the outer side of the threaded valve stem 6. Therefore, the threaded seat 3 in a fixed state can engage with the threaded valve stem 6, thereby realizing the up and down displacement process of the threaded valve stem 6.

[0026] In addition, a propulsion drive assembly is fixedly connected to the right side wall of the inner cavity of the accommodating cavity 5 , and the left side of the propulsion drive assembly is meshed with the driven cone wheel 9 .

[0027] The propulsion drive assembly includes an electric push rod 10 , the output end of which is fixedly connected to a servo motor 11 , the output shaft of the servo motor 11 is coaxially connected to a driving bevel wheel 12 , and the left side of the driving bevel wheel 12 is meshed with the driven bevel wheel 9 .

[0028] In addition, a manual cut-off assembly is fixedly connected to the top of the mounting frame 2 for emergency manual cut-off processing.

[0029] Among them, the manual cutting component includes two damping telescopic rods 13 whose bottoms are fixedly connected to the mounting frame 2, the tops of the two damping telescopic rods 13 are fixedly connected to a fixing frame 14, the front of the fixing frame 14 is connected to a rotating shaft 15 through a bearing, and the top of the rotating shaft 15 is fixedly connected to a handwheel 16.

[0030] It can be understood in the above embodiment that a clamping groove is provided on the inner side wall of the clamping sleeve 8, and a clamping block is fixedly connected to the outer side of the rotating shaft 15. The clamping groove is adapted to the clamping block, so that after the rotating shaft 15 moves down into the clamping sleeve 8, it can be clamped, thereby effectively performing manual rotation processing.

[0031] The working principle of this embodiment is as follows:

[0032] When receiving the signal to cut off the fluid, the servo motor 11 will drive the active cone wheel 12 to rotate, and the active cone wheel 12 will mesh with the driven cone wheel 9, driving the driven cone wheel 9, the telescopic shaft 7 and the threaded valve stem 6 to rotate. After the threaded valve stem 6 is threadedly engaged with the screw seat 3, it will cooperate with the telescopic shaft 7 to perform up and down displacement processing, and then operate the valve core to cut off the fluid. When the servo motor 11 fails, the electric push rod 10 can be started to drive the servo motor 11 to move to the right, thereby releasing the meshing relationship between the active cone wheel 12 and the driven cone wheel 9. At this time, the hand wheel 16 is pressed down to drive the rotating shaft 15 to move downward and enter the clamping sleeve 8 to engage with it. Then, the hand wheel 16 is turned to drive the clamping sleeve 8, the telescopic shaft 7 and the threaded valve stem 6 to rotate, so that the threaded valve stem 6 is threadedly engaged again, and the up and down displacement operation is performed to realize the manual fluid cutting process, and the overall purpose of quickly cutting off the fluid is achieved.
