BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic cross-sectional view of a remote control device applied to a ball valve according to an embodiment of the present utility model.

[0017] Figure 2 is an enlarged schematic view of part A in an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Refer to Figure 1-2, what is disclosed in the embodiment of the present utility model is a remote control device applied to a ball valve, including a valve body 1, a valve cover 3 provided on the valve body 1, a water inlet channel 2 and a water outlet channel opened in the valve body 1, a sphere provided between the water inlet channel 2 and the water outlet channel, and a sealing cover 4. A valve rod is provided in the valve body 1. One end of the valve rod is connected to the sphere, and the other end of the valve rod passes through the valve cover 3 and is provided with a servo motor 5. A sealing groove is circumferentially opened on the valve cover 3. The end of the sealing cover 4 is provided in the sealing groove to seal the servo motor 5. An anti-opening and closing device for preventing the sealing cover 4 from being opened is provided on the valve cover 3. A control module 6 for controlling the operation of the servo motor 5 is provided in the sealing cover 4. A wireless transmission module 7 connected to the staff's mobile phone is also provided in the sealing cover 4. The control module 6 is electrically connected to the servo motor 5, and the wireless transmission module 7 is electrically connected to the control module 6.

[0020] Specifically, the anti-opening and closing device includes a limit block 15, a screw rod 16, and an opening and closing rod (not shown in the figure). A sliding channel 14 is opened in the valve cover 3. The sliding channel 14 is communicated with the sealing groove. The limit block 15 is slidably arranged in the sliding channel 14. The sealing cover 4 is provided with a limit channel at the position of the sliding channel 14. The limit block 15 can slide into the limit channel. The screw rod 16 is rotatably inserted into the sliding channel 14. One end of the screw rod 16 is in threaded transmission with the limit block 15 to drive the limit block 15 to slide. The other end of the screw rod 16 is located at the end of the valve cover 3 and is linked to the outside. An opening and closing groove 17 is opened on the screw rod 16. The opening and closing rod is arranged to match the opening and closing groove 17. The opening and closing rod is inserted into the opening and closing groove 17. Among them, when in use, when it is necessary to open or close the ball valve, the staff controls the opening or closing of the ball valve through the mobile phone APP. Then the electrical signal is received by the wireless transmission module 7 and then transmitted to the control module 6. Then the control module 6 controls the operation of the servo motor 5. When the servo motor 5 operates, it drives the valve rod to rotate, and the valve rod drives the sphere to rotate, thereby controlling the opening or closing of the ball valve. Thus, it can realize that the staff remotely controls the opening or closing of the ball valve, so that the staff does not need to run to the ball valve to manually open it, which is beneficial to the operation and management of the staff. The sealing cover 4 can cover the internal parts such as the servo motor 5, the control module 6, the wireless transmission module 7, and the valve rod, thereby preventing them from being exposed to wind, sun, rain, and thus protecting its internal parts and increasing its service life. The anti-opening and closing device can prevent others from opening the sealing cover 4, thereby preventing the sealing cover 4 from being stolen or maliciously opened, which is further beneficial to the management of the staff. Only when the staff inserts the opening and closing rod into the opening and closing groove 17 and then rotates the screw rod 16, the screw rod 16 drives the limit block 15 to slide, so that the limit block 15 disengages from the limit channel and releases the engagement between the limit block 15 and the limit channel, thereby opening the sealing cover 4. This further facilitates the management of the staff and is beneficial to the long-term use of the ball valve.

[0021] To prevent impurities in the water flow from loading on the sphere, which may cause easy wear of the sphere and affect the service life of the ball valve, it further includes a filter screen 8 and a brush 9. The filter screen 8 is arranged in the water inlet passage 2 to filter impurities in the water inlet passage 2. There is a water passing seat 11 in the water inlet passage 2 that allows water flow through. An electric push rod 10 is arranged on the water passing seat 11. A rotating motor (not shown in the figure) is arranged in the extending rod of the electric push rod 10. The brush 9 is arranged on the rotating shaft of the rotating motor. The electric push rod 10 and the rotating motor are respectively electrically connected to the control module 6. Among them, when the ball valve is working, the water flow passes through the filter screen 8, and then the filter screen 8 filters out the impurities, thus preventing the impurities from flowing to the sphere and adhering to the sphere, and wearing the sphere, so as to improve the service life of the sphere and further improve the service life of the ball valve. When the filter screen 8 is filtering, the staff operates the mobile phone APP to control the electric push rod 10 and the rotating motor to work. The electric push rod 10 extends, making the brush 9 resist against the filter screen 8, and the rotating motor rotates, driving the brush 9 to rotate, so as to clean the impurities on the filter screen 8, thus improving the filtering capacity of the filter screen 8. After cleaning, the electric push rod 10 returns to its original position, separating the brush 9 from the filter screen 8, so that the brush 9 will not block the filter screen 8 and affect the water flow rate, which is beneficial to the water flow through.

[0022] To facilitate the discharge of impurities and dirt inside the water inlet passage 2, the valve body 1 is provided with a sewage discharge passage 13 at the position of the water inlet passage 2, and a sewage plug 12 is threadedly connected in the sewage discharge passage 13.

[0023] To facilitate the impurities to fall into the sewage discharge passage 13, the sewage discharge passage 13 is arranged in a conical shape.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and descriptions only illustrates the principles of the present invention.
