[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a hydraulic engineering control valve device. Figure 1-4 As shown, it includes a control valve body 1, a connecting flange 2 is integrally formed on the outer wall of one side of the control valve body 1, and there are two connecting flanges 2, and the two connecting flanges 2 are symmetrically arranged on the outer wall of the control valve body 1. An outer fixing sleeve 3 is welded at the top center position of the control valve body 1, and an inner rotating sleeve 4 is screwed together at the top center position of the outer fixing sleeve 3. The internal spaces of the control valve body 1, the outer fixing sleeve 3 and the inner rotating sleeve 4 are all connected, and an outer wheel disc 5 is welded on the outer wall of the inner rotating sleeve 4. 4 is screwed with a valve stem 6 at the top center position through a thread, a fixing platform 8 is welded to the top of the inner rotating sleeve 4 near the outer side position of the valve stem 6, a latch 9 is passed through the outer side wall of the fixing platform 8 and the valve stem 6, an inner wheel 7 is welded to the outer side wall of the valve stem 6, and the bottom end of the valve stem 6 is rotatably connected to the valve seat 10, and the bottom of the valve seat 10 is integrally formed with a valve plate 11, and a valve seat limiting groove 12 is opened inside the control valve body 1 near the outer side position of the valve seat 10, and the valve seat 10 and the valve seat limiting groove 12 are slidably connected.

[0023] It should be noted that, since the existing water conservancy project control valve needs to rotate the valve stem for a long time to close the valve in the event of an emergency flood, this is very time-consuming and inconvenient for rapid closing. This embodiment uses two ways of opening and closing the valve, which can be selected according to needs. After the inner rotating sleeve 4 and the valve stem 6 are connected and fixed by the pin 9, the valve can be closed by simply rotating the outer wheel 5 one circle. The valve control speed is fast and the time is short. The valve can be closed in time in the event of an emergency flood. The valve plate 11 can also be raised and lowered by rotating the inner wheel 7. The inner wheel 7 needs to be rotated multiple times, but it is also more labor-saving.

[0024] Specifically, in this embodiment, this solution mainly includes an inner rotating sleeve 4 and a valve stem 6. When in use, the control valve body 1 is installed and fixed to one end of the pipeline using the connecting flange 2. When encountering an emergency water conservancy message and needing to quickly close the valve, the latch 9 is inserted through the pin holes on the fixing platform 8 and the valve stem 6 to achieve fixation between the fixing platform 8 and the valve stem 6, and then achieve fixation between the valve stem 6 and the inner rotating sleeve 4. The water conservancy engineering personnel hold the outer wheel 5 and rotate the outer wheel 5. Through the screw connection of the inner rotating sleeve 4 on the outer fixed sleeve 3, the inner rotating sleeve 4 drives the valve stem 6 to rotate. Since the valve seat 10 is on the valve seat The limiting groove 12 is slidingly connected, and the valve stem 6 and the valve seat 10 are rotationally connected. When the valve stem 6 is threadedly rotated and descended, the valve seat 10 and the valve plate 11 at the bottom of the valve stem 6 are synchronously descended, and the valve plate 11 is inserted into the channel in the control valve body 1 to realize the interception of the control valve body 1. Since the outer diameter of the inner rotating sleeve 4 is large and the outer diameter of the outer wheel 5 is large, the valve can be closed by rotating the outer wheel 5 one circle, and the control speed of the valve is fast. When the interception information is not urgent, the valve plate 11 can be raised and lowered by rotating the inner wheel 7. Since the outer diameter of the valve stem 6 is small, the inner wheel 7 needs to be rotated multiple circles, but it is also more labor-saving.

[0025] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer diameter of the outer wheel disc 5 is larger than the outer diameter of the inner wheel disc 7 .

[0026] In this embodiment, the outer wheel disc 5 can be rotated more conveniently, which facilitates the rotation of the outer wheel disc 5 .

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, there are two fixing platforms 8, and the two fixing platforms 8 are symmetrically arranged on the top of the inner rotating sleeve 4. Pin holes for the insertion of the plug 9 are opened on the outer wall of one side of the valve stem 6 and the fixing platform 8.

[0028] In this embodiment, by providing two fixing platforms 8 and inserting the latch 9, the valve stem 6 and the inner rotating sleeve 4 are fixed to each other, thereby preventing the valve stem 6 from rotating when the inner rotating sleeve 4 rotates.
