The output end of the motor drive assembly, located on the upper side of the three-way valve body, is connected to the two sets of ball valve assemblies respectively through the gear mechanism and the incomplete gear mechanism to control the opening and closing of the two sets of ball valve assemblies. This design achieves a compact structure and simple operation. The working position can be switched by controlling the motor drive assembly, and the current working position is maintained even after power failure, saving energy and improving the service life of the device.

[0004] However, this does not solve the problem that existing three-way ball valves are generally not suitable for using a T-shaped flow ball structure to control the flow of each valve port, are not conducive to rapid rotation control of the flow direction by electric control, affect the degree of automation of the equipment, increase the cost and risk of manual intervention, are not convenient for electric drive and manual drive, and are prone to failure to open the electric three-way ball valve when the power is off. Summary of the Invention

[0005] The purpose of this utility model is to provide an electric three-way ball valve to solve the problems mentioned in the background art, such as the inconvenience of using a T-shaped flow ball structure to control the flow of each valve port, the inconvenience of electric control to quickly rotate and control the flow direction, the impact on the automation level of the equipment, the increase in the cost and risk of manual intervention, the inconvenience of electric drive and manual drive, and the easy occurrence of the electric three-way ball valve failing to open when power is cut off.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric three-way ball valve, comprising a valve seat and a second-way pipe, wherein the second-way pipe is installed on the outer wall of the valve seat, a first-way pipe is installed on the outer wall of the valve seat on one side of the second-way pipe, and a third-way pipe is installed on the outer wall of the valve seat on the other side of the second-way pipe. A T-shaped flow ball is provided at the center position inside the valve seat. A support seat is installed at the top of the valve seat, a control box is installed at the top of the support seat, a servo motor is installed at the top of the control box, a valve stem is installed at the top of the T-shaped flow ball, and the valve stem extends into the interior of the control box. A fourth gear is fitted on the surface of the valve stem, a first right-angle gear is fitted on the surface of the valve stem below the fourth gear, and a first gear is installed at the output end of the servo motor.

[0007] Preferably, a second gear is installed inside the control box on one side of the first gear, and a third gear is installed at the bottom of the second gear, and the third gear meshes with the fourth gear.

[0008] Preferably, a power shaft is installed inside the control box on one side of the first right-angle gear, and a positioning sleeve is fitted on the surface of the power shaft.

[0009] Preferably, a protrusion is installed at the end of the power shaft away from the second right-angle gear, and a groove sleeve is slidably fitted on the surface of the protrusion. A positioning seat is installed on the outer wall of the control box on one side of the groove sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this three-way ball valve not only realizes the convenient control of the flow rate of each valve port by adopting a T-shaped flow ball structure, which facilitates the rapid rotation control of the flow direction by electric control, improves the automation level of the equipment, and reduces the cost and risk of manual intervention, but also facilitates both electric drive and manual drive, avoiding the problem that the electric three-way ball valve cannot be opened when the power is off.

[0015] (1) The third, second and first pipes are connected to the external pipes. The T-type flow ball controls the opening and closing of the third, second and first pipes. The T-type flow ball adopts the T-type flow ball structure to be widely used to obtain two inlet flows and merge them to flow out through a common outlet. According to the process requirements, it can also be the opposite, that is, the flow from a common port is divided into two outflow flows. Each flow leaves the valve through a different valve port, realizing the convenient use of the T-type flow ball structure to control the flow of each valve port of the electric three-way ball valve, which facilitates the convenient control of the inflow or outflow of the valve port.

[0016] (2) The first gear is driven to rotate by the servo motor, the second gear drives the third gear to rotate, the third gear drives the fourth gear to rotate, the fourth gear drives the valve stem to rotate, the valve stem drives the T-shaped flow ball to rotate, and the T-shaped flow ball controls the inflow or outflow of the third, second and first pipes, realizing the stable electric control mechanical transmission of the electric three-way ball valve, which facilitates the rapid rotation control of the flow direction by electric control, improves the automation level of the equipment, and reduces the cost and risk of manual intervention;

[0017] (3) The handwheel is driven to move laterally by manual operation. The handwheel drives the rotating shaft to move laterally, and the rotating shaft drives the groove sleeve to move. The groove sleeve moves to the surface of the protrusion. The handwheel is rotated manually. The handwheel drives the groove sleeve, protrusion, power shaft and second right-angle gear to rotate through the rotating shaft. The second right-angle gear drives the first right-angle gear to rotate, so that the first right-angle gear drives the valve stem to rotate, so as to facilitate manual operation and control. This realizes the multi-mode operation and control of the electric three-way ball valve, which facilitates electric drive and manual drive, and avoids the problem that the electric three-way ball valve cannot be opened when the power is off.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Example

[0029] Please see Figure 1-7An embodiment of this utility model provides: an electric three-way ball valve, including a valve seat 1 and a second-way pipe 4. The second-way pipe 4 is installed on the outer wall of the valve seat 1. A first-way pipe 2 is installed on the outer wall of the valve seat 1 on one side of the second-way pipe 4. A third-way pipe 5 is installed on the outer wall of the valve seat 1 on the other side of the second-way pipe 4. A T-shaped flowing ball 3 is provided at the center position inside the valve seat 1. A support seat 6 is installed at the top of the valve seat 1. A control box 7 is installed at the top of the support seat 6. A servo motor 8 is installed at the top of the control box 7.

[0030] The T-type flow ball 3 connects to external pipelines via the third pipe 5, second pipe 4, and first pipe 2. It controls the opening and closing of these pipes. The T-type flow ball 3, with its T-shaped structure, is widely used to capture two inlet flows and merge them to exit through a common outlet. Alternatively, depending on process requirements, it can be used in reverse, splitting the flow from a common port into two outflows, each exiting through a different valve port. T-type flow valves are not limited to flow splitting or diversion; they can also function like L-type flow valves, transferring flow from one outlet to another. Importantly, T-type flow ball valves differ significantly from L-type flow ball valves. Typical T-type flow valves cannot provide shut-off control; they can limit flow to any two of the three valve ports or allow flow through all three ports simultaneously. This allows for convenient control of flow at each valve port using the T-type flow ball structure, facilitating easy control of inflow and outflow.

[0031] The top of the T-shaped ball 3 is equipped with a valve stem 14, which extends into the interior of the control box 7. A fourth gear 13 is fitted on the surface of the valve stem 14, and a first right-angle gear 15 is fitted on the surface of the valve stem 14 below the fourth gear 13. A first gear 9 is installed at the output end of the servo motor 8.

[0032] The control box 7 on one side of the first gear 9 is equipped with the second gear 10. The bottom of the second gear 10 is equipped with the third gear 11, and the third gear 11 meshes with the fourth gear 13. The control box 7 on one side of the first right-angle gear 15 is equipped with the power shaft 12, and the surface of the power shaft 12 is fitted with the positioning sleeve 26.

[0033] The servo motor 8 drives the first gear 9 to rotate, which in turn drives the second gear 10 to rotate under the meshing of the first gear 9 and the second gear 10. The second gear 10 drives the third gear 11 to rotate, the third gear 11 drives the fourth gear 13 to rotate, and the fourth gear 13 drives the valve stem 14 to rotate. The valve stem 14 drives the T-shaped flow ball 3 to rotate. The T-shaped flow ball 3 controls the inflow or outflow of the third pipe 5, the second pipe 4, and the first pipe 2, realizing stable electric control mechanical transmission of the electric three-way ball valve. This facilitates the rapid rotation control of the flow direction by electric control, improves the automation level of the equipment, and reduces the cost and risk of manual intervention.

[0034] A protrusion 23 is installed at the end of the power shaft 12 away from the second right-angle gear 16. A groove sleeve 21 is slidably fitted on the surface of the protrusion 23. A positioning seat 19 is installed on the outer wall of the control box 7 on one side of the groove sleeve 21. A rotating shaft 20 is installed at the end of the groove sleeve 21 near the positioning seat 19, and the rotating shaft 20 extends to the outside of the positioning seat 19.

[0035] The rotating shaft 20 is slidably connected to the positioning seat 19. A handwheel 18 is installed at the end of the rotating shaft 20 away from the positioning seat 19. A slider 17 is fitted on the surface of the groove sleeve 21. Support columns 25 are symmetrically installed on the outer wall of the positioning sleeve 26.

[0036] A spring 24 is installed at the end of the support column 25 away from the positioning sleeve 26, and a slider 22 is installed at the end of the spring 24 away from the support column 25, and the slider 22 is slidably connected to the slider 17.

[0037] When the power is off and the electric three-way ball valve needs to be opened manually, the manual drive handwheel 18 moves laterally. At this time, the manual driving force is greater than the elastic force of spring 24. Handwheel 18 drives the rotating shaft 20 to move laterally, and the rotating shaft 20 drives the groove sleeve 21 to move. The groove sleeve 21 moves to the surface of the protrusion 23. The manual rotation of handwheel 18 drives the groove sleeve 21, protrusion 23, power shaft 12, and second right-angle gear 16 to rotate via the rotating shaft 20. The second right-angle gear 16 drives the first right-angle gear 15 to rotate, so that the first right-angle gear 15 drives the valve stem 14 to rotate, which facilitates manual operation control. When the servo motor 8 is driven, the power shaft 1... The positioning sleeve 26 supports the support column 25, and the spring 24 provides elastic support for the slider 22. The slider 22 elastically drives the slider 17 to move, and the slider 17 drives the groove sleeve 21 to move and disengage from the protrusion 23 to prevent the handwheel 18 from rotating synchronously when the servo motor 8 is driven. When the servo motor 8 controls the power shaft 12 to rotate, the power shaft 12 drives the positioning sleeve 26, support column 25, spring 24, and slider 22 to rotate. The slider 17 provides sliding support for the slider 22, realizing multi-mode operation control of the electric three-way ball valve, facilitating electric drive and manual drive, and avoiding the problem that the electric three-way ball valve cannot be opened when the power is off.

[0038] Work steps

[0039] First, the system connects to external pipes via the third pipe 5, the second pipe 4, and the first pipe 2. The T-shaped flow ball 3 controls the flow of these pipes. The T-shaped flow ball 3 uses a T-shaped flow ball structure. The servo motor 8 drives the first gear 9 to rotate, the second gear 10 drives the third gear 11 to rotate, the third gear 11 drives the fourth gear 13 to rotate, and the fourth gear 13 drives the valve stem 14 to rotate. The valve stem 14 then rotates the T-shaped flow ball 3, which controls the inflow or outflow of the three pipes. When the power is off, manual re-energization is required. When operating the three-way ball valve, the manual drive handwheel 18 moves laterally. At this time, the manual driving force is greater than the elastic force of the spring 24. The handwheel 18 drives the rotating shaft 20 to move laterally, and the rotating shaft 20 drives the groove sleeve 21 to move. The groove sleeve 21 moves to the surface of the protrusion 23. The manual rotation of the handwheel 18 drives the groove sleeve 21, the protrusion 23, the power shaft 12, and the second right-angle gear 16 to rotate via the rotating shaft 20. The second right-angle gear 16 drives the first right-angle gear 15 to rotate, so that the first right-angle gear 15 drives the valve stem 14 to rotate, so as to facilitate manual operation and control to complete the use of the three-way ball valve.

[0040] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
