DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] A novel intelligent electric ball valve actuator comprises a housing, a base, a control motor, a control block, a first microswitch, and a second microswitch. The housing and base overlap, forming a sealed cavity between them. The control motor, control block, first microswitch, and second microswitch are disposed within the sealed cavity. The control motor is mounted on the base, and the control block is mounted on the main shaft of the control motor. The first and second microswitches are fixedly mounted to the base. Rotation of the control block triggers the first and second microswitches, respectively. The control block is shaped like a right-angled sector, with a first contact plane and a second contact plane on either side of its curved surface. The first and second microswitches are disposed on the same side of the control block, mirroring each other. The mirror planes of the first and second microswitches are located on the centerline of the curved surface of the control block. The base is also provided with first, second, and third stop posts. The first microswitch is fixed between the first and second stop posts, and the second microswitch is fixed between the second and third stop posts. The second limit post is located on a mirror image of the first and second micro switches. A control circuit board is also provided on the back of the first and second micro switches, and the first and second micro switches are respectively welded and fixed to the control circuit board. A fourth limit post is also provided between the control circuit board and the inner wall of the base, and the control circuit board is clamped and fixed between the fourth limit post and the first, second, and third limit posts. The base is also provided with a first limit post, a second limit post, and a third limit post, and the first micro switch is fixed between the first and second limit posts, and the second micro switch is fixed between the second and third limit posts. A fourth limit post is also provided between the control circuit board and the inner wall of the base, and the control circuit board is clamped and fixed between the fourth limit post and the first, second, and third limit posts. The first and second micro switches are provided with first positioning holes, corresponding to the mounting holes provided on the base. The first and second micro switches are fixed to the base using bolts. The first micro switch and the second micro switch are further provided with a second positioning hole, and a fifth limiting column is provided at the corresponding base, and the second positioning hole is sleeved on the fifth limiting column.

[0037] Example 2:

[0038] The first and second microswitches are electrically connected to a control circuit board, which is fixedly mounted on the back of the housing. This control circuit board houses a data transmission module, which transmits signals to a control terminal, such as a mobile phone. The module then transmits signals to the control terminal, which in turn provides a signal to control the motor's forward or reverse rotation. The control circuit board also features an indicator light that reflects the actuator's status, visible through the housing.

[0039] The actual usage is as follows:

[0040] The operation of the control motor is controlled by an external signal, which is usually provided by a terminal signal or a sensor. The control motor drives the control block and the valve core to rotate. The control block is used to trigger the first micro switch and the second micro switch. The first micro switch and the second micro switch mainly provide a stop signal. Figure 3 As shown, when the control block rotates counterclockwise and triggers the first micro switch, the control motor stops rotating counterclockwise. Conversely, when the control block rotates clockwise and triggers the second micro switch, the control motor stops rotating clockwise.

[0041] During assembly, the control circuit board is clamped and fixed between the fourth limit column and the first limit column, the second limit column and the third limit column, the first micro switch and the second micro switch are mounted on the fifth limit column, and the first micro switch and the second micro switch are fixed to the base using bolts through the second positioning hole.

[0042] When the actuator is connected to the copper valve, a straight positioning column is inserted into the connection positioning hole to achieve rapid positioning. A base is set between the two, and the connection between the two is completed through an internal threaded connecting sleeve and an external threaded column, making the connection between the two tighter.

[0043] Connection between actuator, connecting seat and copper valve:

[0044] The actuator has four mounting holes and four locating holes at the bottom. First, place the outer nut over the bottom of the actuator, then connect the connector to the bottom of the actuator. The mounting bolts pass through the bolt mounting holes on the connector and connect to the four mounting holes of the actuator. The four locating posts at the top of the connector fit into the four locating holes. Once the connector is installed, the outer nut is also held in place at the top of the connector. Next, insert the four locating posts at the bottom of the connector into the four through-holes at the top of the copper valve. Two of the four locating posts are special-shaped, with a circular cross-section on the side where they connect to the valve body. This shape helps determine the direction of the actuator when assembling the copper valve. The top of the control block is connected to the control motor shaft, and the bottom is connected to the copper valve stem. Finally, engage the outer nut with the threaded structure at the top of the valve, completing the assembly of the actuator, connector, and copper valve.

[0045] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
