Description

Technical Field

[0001] This utility model relates to the field of multi-way valve technology, specifically a multi-way valve electric drive device. Background Technology

[0002] A multi-way valve is a combination valve consisting of two or more directional valves. Through modular design, the valve body can be combined according to different functional requirements to provide a reliable system solution. Multi-way valves can be combined with various auxiliary valves such as safety valves, overload valves, replenishing valves, diverting valves, braking valves, and check valves to control the movement of multiple actuators.

[0003] According to the utility model authorized by announcement number CN220365979U, an electric multi-way switching valve is disclosed, including a valve housing, an inlet and at least two outlets on the valve housing, and a valve cover that is detachably connected to the valve housing, forming an installation cavity between the valve housing and the valve cover.

[0004] Although this device controls the rotation of the valve core through a drive unit, making it easy to operate and allowing for flexible switching of flow direction to meet different process requirements and fluid control needs, it can only control the flow of liquid in a single valve and cannot control the liquid in multiple valves, resulting in low adaptability of the multi-way valve. To address this issue, we provide an electric drive device for multi-way valves. Utility Model Content

[0007] Furthermore, the outer surfaces of the two first fixed housings and the outer surfaces of the second fixed housing are jointly fixedly connected to two limiting frames, and the bottom surface of each limiting frame is fixedly connected to the upper surface of the base.

[0008] Furthermore, each of the limiting frames has two fixing bolts threadedly connected to its inner wall, and the outer surface of each set of fixing bolts is threadedly connected to the inner wall of the base.

[0010] Furthermore, two fixing rods are fixedly connected to the sides of the two limiting frames that are close to each other. Two reinforcing rings are fixedly connected to the outer surface of each fixing rod. The ends of each set of reinforcing rings that are far apart from each other are fixedly connected to the sides of the two limiting frames that are close to each other.

[0011] Furthermore, a protective box is fixedly connected to the outer surface of each stepper motor, and the bottom surface of each protective box is fixedly connected to the upper surface of the base.

[0012] Compared with the prior art, this multi-way valve electric drive device has the following advantages:

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] This embodiment provides a multi-way valve electric drive device, which is used to facilitate the control of liquid flow in drainage pipes and water inlet pipes, to facilitate the opening and closing of each pipe, and to facilitate the use of each pipe by the staff according to actual needs, with the effect of multiple combined use methods.

[0021] See Figure 1 A multi-way valve electric drive device includes a base 1, and a control mechanism 2 is arranged above the base 1. The control mechanism 2 includes two first fixed housings 201 and a second fixed housing 202. The upper surface of each first fixed housing 201 and the upper surface of each second fixed housing 202 are fixedly connected to a water inlet pipe 203. The outer surfaces of the two first fixed housings 201 and the outer surfaces of the second fixed housing 202 are jointly fixedly connected to two limiting frames 4. The bottom surface of each limiting frame 4 is fixedly connected to the upper surface of the base 1. Through the limiting frames 4, the position of the first fixed housings 201 and the second fixed housings 202 can be restricted, thereby playing a fixed and limiting role.

[0022] See Figure 1 and Figure 3 Two bearings 209 are fixedly connected to the inner wall of each first fixed housing 201 and the inner wall of each second fixed housing 202. Three stepper motors 211 are fixedly connected to the upper surface of the base 1. A rotating gear 210 is fixedly connected to the output end of each stepper motor 211. Two fixing bolts 5 are threadedly connected to the inner wall of each limiting frame 4. The outer surface of each set of fixing bolts 5 is threadedly connected to the inner wall of the base 1. The position of the limiting frame 4 can be fixed by the fixing bolts 5 to prevent it from shifting during use.

[0023] See Figure 1 , Figure 3 and Figure 4The outer surface of each rotating gear 210 is fixedly connected to the inner ring of the bearing 209. Two rotating gears 210 have two first racks 208 meshing on their outer surfaces, and the outer surface of the other rotating gear 210 has a second rack 213 meshing on its outer surface. Each water inlet pipe 203 has a fixing ring 3 fixedly connected to its outer surface. The bottom ends of two fixing rings 3 are fixedly connected to the upper surface of the first fixing housing 201, and the bottom end of the other fixing ring 3 is fixedly connected to the upper surface of the second fixing housing 202. The fixing rings 3 can fix the water inlet pipe 203 and prevent it from swaying during operation.

[0024] See Figure 2 , Figure 3 and Figure 4 Each first rack 208 has a first movable plate 205 fixedly connected to its bottom surface, and a second movable plate 212 fixedly connected to its bottom surface. Two fixed rods 7 are fixedly connected to the side of the two limiting frames 4 that are close to each other. Two reinforcing rings 8 are fixedly connected to the outer surface of each fixed rod 7. The ends of each set of reinforcing rings 8 that are far apart from each other are fixedly connected to the side of the two limiting frames 4 that are close to each other. The fixed rods 7 and the reinforcing rings 8 can fix the position of the two limiting frames 4, thereby enhancing the stability of the device.

[0025] See Figure 1 , Figure 3 and Figure 4 Each of the upper surfaces of the first movable plate 205 and the second movable plate 212 is fixedly connected with a rubber plug 206 and a locking block 207. The inner wall of the base 1 is fixedly connected with three drainage pipes 204. Each of the outer surfaces of the stepper motor 211 is fixedly connected with a protective box 6. The bottom surface of each protective box 6 is fixedly connected to the upper surface of the base 1. The protective box 6 can protect the stepper motor 211 and prevent it from being interfered with by external factors during use.

[0026] Working principle: In use, first connect the water inlet pipe 203 to the external water pipe. Control the output end of the stepper motor 211 to rotate according to the actual use requirements. This will drive the rotating gear 210 to rotate in the inner ring of the bearing 209, thereby driving the first movable plate 205 and the second movable plate 212 to move respectively. When the first movable plate 205 and the second movable plate 212 move to the left, the through hole on the locking block 207 corresponds to the water inlet pipe 203. Thus, the liquid in the water inlet pipe 203 can pass through the through hole on the locking block 207, the first movable plate 205 and the second movable plate 212 in sequence, and then be discharged out through the drain pipe 204.

[0027] When the first movable plate 205 and the second movable plate 212 move to the right, the rubber plug 206 can block the water inlet pipe 203 to prevent liquid from flowing out. Furthermore, the three stepper motors 211 can be controlled individually, thereby enabling multiple pipes to be used in various combinations, enhancing the effectiveness of the device. This effectively avoids the problem of low adaptability of multi-way valves, which can only control the flow of liquid in a single valve but cannot control the liquid in multiple valves.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
