[0002] Valves are piping accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow) of the conveyed medium. Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow and pressure relief. Valves are used in fluid control systems.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] according to Figure 1-Figure 3As shown, it includes a valve body 1, a sealing ring 11 is installed at the middle position of the outer surface of the valve body 1, and the inner wall of the valve body 1 is rotatably connected to the middle position of the sealing ring 11. The setting of the sealing ring 11 can perform a corresponding sealing effect on the gap between the inner wall of the valve body 1 and the rotating rod 2. One end of the rotating rod 2 passes through the interior of the sealing ring 11, and one end of the rotating rod 2 passes through the inner wall of the valve body 1 and extends to the interior of the valve body 1. A valve 21 is installed at the bottom end of the rotating rod 2, and a driving gear 23 is installed on the outer surface of the rotating rod 2. When the interior of the valve body 1 is in a closed state, the valve 21 will be placed horizontally in the interior of the valve body 1. The outer diameter of the valve 21 is adapted to the inner diameter of the valve body 1, and the valve 21 is arranged inside the valve body 1. A support rod 22 is installed at the top of the rotating rod 2, and the top of the support rod 22 is installed with the bottom end of the top plate 31 through a bearing.

[0020] The outer surface of the valve body 1 is installed with support plates 3 on both sides of the rotating rod 2, and the top of the support plates 3 is installed with the bottom end of the top plate 31, and the bottom end of the support plate 3 is installed with a mounting rod 32 on one side, and the bottom end of the mounting rod 32 is installed with a mounting ring 33, an electric push rod 34 is installed inside the mounting ring 33, and one end of the electric push rod 34 is installed with a fixing rod 36 through a mounting plate 35, the electric push rod 34 is installed with the top inner wall of the top plate 31 through the mounting ring 33 and the mounting rod 32, so that the setting of the mounting rod 32 and the mounting ring 33 can support the electric push rod 34, and one end of the electric push rod 34 is installed with one side surface of one group of support plates 3.

[0021] A motor 4 is installed on the outer surface of the valve body 1 at a position close to the driving gear 23, and a driving gear 41 is installed on the output end of the motor 4 through a transmission shaft. The driving gear 41 is meshed with the driving gear 23. A limiting rod 42 is installed on the top of the driving gear 41, and the top of the limiting rod 42 is installed with the bottom end of the top plate 31 through a bearing.

The shape of the cross limiting hole 43 is cross-shaped.

[0022] When the interior of the valve body 1 needs to be in an open state, it is only necessary to start the electric push rod 34 first, so that under the operation of the electric push rod 34, the mounting plate 35 can be moved to one side, so that the fixing rod 36 can be moved to one side, so that the fixing rod 36 can be moved out of the interior of the cross limit hole 43. After that, the user can start the motor 4, so that under the operation of the motor 4, the driving gear 41 can be rotated accordingly, so that the limit rod 42 can be rotated accordingly, so that The driving gear 23 can rotate accordingly, so that the rotating rod 2 and the support rod 22 can rotate accordingly, so that the valve 21 can rotate accordingly. When the valve 21 is rotated to 90°, the motor 4 can be closed. At this time, the valve 21 will be vertically located inside the valve body 1. At this time, the interior of the valve body 1 is in an open state. After that, one end of the fixing rod 36 can be extended into the interior of the cross limit hole 43 through the electric push rod 34 and the corresponding limit clamping setting is performed, so that the driving gear 41 and the limit rod 42 cannot rotate at will.
