Description

Technical Field

[0001] This utility model belongs to the field of solar water heater valve technology, and in particular relates to a solar electric ball valve. Background Technology

[0002] A ball valve is a type of valve that opens or closes by rotating a ball 90° around the valve stem axis; it belongs to the shut-off valve category. Its core structure is a ball with a central through-hole. The rotation of the ball controls the flow of fluid. It features simple structure, good sealing performance, and convenient operation, and can be used to control the water flow in solar water heaters.

[0003] Because conventional electric ball valves need to be switched between manual and electric modes, the electric mode cannot operate when switched to manual mode, and the electric mode is locked and cannot be operated manually when switched to electric mode. The two operating modes need to be switched, and forcibly integrating the structure that switches between the two modes will cause mutual interference, thus making the manual-electric switching operation of conventional electric ball valves quite troublesome.

[0004] Therefore, we propose a solar-powered electric ball valve to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the cumbersome manual-electric switching operation of conventional electric ball valves, and to propose a solar-powered electric ball valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solar-powered electric ball valve includes a ball valve body and a motor. A frame is fixedly mounted on the upper part of the ball valve body. The upper end of the motor is fixedly connected to the frame. A lifting block is slidably mounted inside the frame. A micro switch is installed inside the frame. A threaded column is rotatably mounted inside the frame. The lower end of the threaded column is engaged with the operating rod of the ball valve body. A gear disk is fixedly connected to the lower part of the threaded column. The motor is located inside the gear disk and does not contact the motor. A gear is fixedly connected to the rotor of the motor, and the gear meshes with the gear disk. The system utilizes a motor to drive a gear, which in turn drives a gear disc to rotate slowly. This gear disc, in turn, drives a threaded rod, which in turn drives the ball valve's operating lever. Simultaneously, this causes the lifting block to rise. When the rising lifting block presses against the upper microswitch, the microswitch sends an electrical signal, indicating that the ball valve is open. Similarly, the reverse drive moves the lifting block back to its original position, causing it to press against the lower microswitch and send an electrical signal, indicating that the ball valve is closed. Manual operation of the threaded rod rotates, causing it to drive the lifting block. When switching back to electric operation, the microswitch provides positioning, preventing manual control from interfering with the electric process and facilitating flexible switching.

[0008] Preferably, it also includes a handle, the lower end of which is fixedly connected to the upper end of the threaded post. The handle provides an operating lever for the threaded post, facilitating manual operation of its rotation.

[0009] Preferably, the frame includes a frame body, guide columns, and bearing seats. The bearing seats are fixedly connected to the lower part of the frame body, and the upper end of the guide columns is fixedly connected to the inside of the frame body. A motor drives a gear to rotate, which in turn drives a gear disc to rotate, which in turn drives a threaded column to rotate, facilitating the electric drive of the threaded column's rotation.

[0010] Preferably, the frame further includes a retaining ring, which is fixedly connected to the outside of the ball valve body. The retaining ring increases the mounting range between the frame and the ball valve body, improving the stability between them.

[0011] Preferably, the threaded column includes a threaded rod body, a rotating rod, and a retaining sleeve. The upper end of the retaining sleeve is fixedly connected to the lower end of the gear disk, the lower end of the threaded rod body is fixedly connected to the center of the gear disk, and the upper end of the threaded rod body is fixedly connected to the lower end of the rotating rod. When the gear disk rotates, it drives the threaded rod body to rotate, and the threaded rod body acts on the retaining sleeve, causing the threaded column to drive the ball valve body operating rod to rotate, facilitating the electric drive of the ball valve body operating rod.

[0012] Preferably, the lifting block includes a nut and a rotation limiting block, with the nut externally fixedly connected to the side of the rotation limiting block. When the threaded rod body rotates, the nut is raised or lowered via the threaded rod body, and the rotation limiting block facilitates the pressing of the micro switch to send a positioning electrical signal.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. The motor drives the gears to rotate, which in turn drives the gear disc to rotate slowly. The gear disc then drives the threaded rod to rotate, which in turn drives the ball valve body's operating lever to rotate. Simultaneously, the lifting block rises. When the lifting block rises and presses the upper micro switch, the micro switch sends an electrical signal, indicating that the ball valve body is open. Similarly, the reverse drive moves the lifting block back to its original position, causing it to press the lower micro switch and send an electrical signal, indicating that the ball valve body is closed. The threaded rod can be manually rotated, causing it to drive the lifting block to rotate. When switching back to electric operation, the micro switch provides positioning, avoiding manual control interference with the electric process and facilitating flexible switching between operations.

[0015] 2. The motor drives the gear to rotate, which in turn drives the gear disc to rotate, which in turn drives the threaded column to rotate, making it convenient to drive the threaded column to rotate electrically.

[0016] 3. When the gear disc rotates, it drives the threaded rod body to rotate. The threaded rod body acts on the snap-fit ​​sleeve, causing the threaded column to drive the ball valve body operating rod to rotate, which facilitates the electric drive of the ball valve body operating rod.

The lower end of the threaded column 3 is engaged with the operating rod of the ball valve body 1. A gear disk 9 is fixedly connected to the lower part of the threaded column 3. The motor 6 is located inside the gear disk 9. The gear disk 9 does not contact the motor 6. A gear 8 is fixedly connected to the rotor of the motor 6. The gear 8 meshes with the gear disk 9.

[0024] like Figure 1 As shown, it also includes a handle 7, the lower end of which is fixedly connected to the upper end of the threaded post 3. The handle 7 is used to increase the operating lever of the threaded post 3.

[0025] like Figure 1 and 2As shown, the frame 2 includes a frame body 21, a guide post 22, and a bearing seat 23. The bearing seat 23 is fixedly connected to the lower part of the frame body 21, and the upper end of the guide post 22 is fixedly connected to the inside of the frame body 21. A micro switch 5 is installed inside the guide post 22. The lower part of the gear disk 9 does not contact the bearing seat 23, and the lower end of the guide post 22 does not contact the gear disk 9. The motor 6 drives the gear 8 to rotate, which in turn drives the gear disk 9 to rotate, which in turn drives the threaded post 3 to rotate.

[0026] like Figure 1 and 2 As shown, the frame 2 also includes a retaining ring 24, which is fixedly connected to the outside of the ball valve body 1. The retaining ring 24 increases the mounting range between the frame 2 and the ball valve body 1.

[0027] like Figure 1 and 3 As shown, the threaded column 3 includes a threaded rod body 31, a rotating rod 32, and a snap-fit ​​sleeve 33. The upper end of the snap-fit ​​sleeve 33 is fixedly connected to the lower end of the gear disk 9, the lower end of the threaded rod body 31 is fixedly connected to the center of the gear disk 9, and the upper end of the threaded rod body 31 is fixedly connected to the lower end of the rotating rod 32. The snap-fit ​​sleeve 33 is rotatably connected inside the bearing seat 23, and the rotating rod 32 is rotatably mounted on the frame 21. The lower end of the handle 7 is fixedly connected to the upper end of the rotating rod 32. When the gear disk 9 rotates, it drives the threaded rod body 31 to rotate, and the threaded rod body 31 acts on the snap-fit ​​sleeve 33, causing the threaded column 3 to drive the operating rod of the ball valve body 1 to rotate.

[0028] like Figure 1 and 4 As shown, the lifting block 4 includes a nut 41 and a rotation limiting block 42. The nut 41 is externally fixedly connected to the side of the rotation limiting block 42. The rotation limiting block 42 is slidably engaged on the guide post 22, and the nut 41 is threadedly mounted on the threaded rod body 31. When the threaded rod body 31 rotates, it drives the nut 41 to rise or fall, and the rotation limiting block 42 presses the micro switch 5 to send a positioning signal.

[0029] Working principle: Motor 6 drives gear 8 to rotate, which in turn drives gear disc 9 to rotate slowly. Gear disc 9 drives threaded column 3 to rotate, which in turn drives the operating rod of ball valve body 1 to rotate. At the same time, lifting block 4 rises. When lifting block 4 rises and presses the upper micro switch 5, the micro switch 5 sends an electrical signal, indicating that ball valve body 1 is open. Similarly, the reverse drive moves lifting block 4 back to its original position, causing it to press the lower micro switch 5, which sends an electrical signal, indicating that ball valve body 1 is closed. Manual operation of threaded column 3 rotates, causing threaded column 3 to drive lifting block 4 to rotate. When switching back to electric operation, micro switch 5 is used for positioning to avoid manual control interfering with the electric process, thus achieving flexible switching operation.
