Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically a quick shut-off device for heating network valves. Background Technology

[0002] Heating networks may experience various unforeseen events during operation, such as pipe ruptures and leaks. If valves are not shut off promptly in such situations, large amounts of high-temperature hot water or steam will continue to leak, resulting in significant energy waste and posing a substantial threat to the surrounding environment and human safety. Modern heating systems require rapid response capabilities to adapt to different operating conditions. When a fault occurs in a section of the heating system, such as a localized pipe blockage or equipment damage, the corresponding valves must be shut off quickly to prevent the impact of the fault from spreading.

[0003] Existing devices mainly control the opening and closing of heating pipe networks through various valve bodies. This makes it difficult for some devices to stably close the internal channel of the ball through the valve core, resulting in inconvenience in timely closing of the valves in the heating pipe network. At the same time, some devices have difficulty in automatically controlling the size of the flow channel inside the valve body, resulting in inconvenience in accurately controlling the flow rate of the fluid inside the valve body, thus reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a rapid shut-off device for heating pipe network valves is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a quick shut-off device for heating pipeline valves, in order to solve the problem mentioned in the background art that the existing devices mainly control the opening and closing of the heating pipeline through various valve bodies. This makes it difficult for some devices to stably shut off the internal channel of the ball through the valve core, thus making it inconvenient to close the valves of the heating pipeline in a timely manner. At the same time, some devices are difficult to automatically control the size of the flow channel inside the valve body, thus making it inconvenient to accurately control the flow rate of the fluid inside the valve body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick shut-off device for a heating network valve, comprising a valve body, a transmission box fixedly connected to the bottom of the valve body, a ball disposed inside the valve body, a valve core inserted into the lower part of the ball, an adjustment box fixedly connected to the top of the valve body, and a controller fixedly connected to the front side of the adjustment box; The transmission box is equipped with a quick-closing mechanism, which includes an electromagnet. The bottom of the outer wall of the electromagnet is fixedly connected to the bottom of the transmission box. The adjustment box is equipped with an adjustment mechanism, which includes a servo motor. The left side of the servo motor is fixedly connected to the right side of the adjustment box.

[0006] Preferably, a permanent magnet is provided above the electromagnet, and a push rod is fixedly connected to the top center of the permanent magnet, with the top end of the push rod fixedly connected to the bottom center of the valve core.

[0007] Preferably, a retaining plate is fixedly connected to the middle of the outer wall of the push rod, and a spring piece is engaged on the outer wall of the retaining plate. The lower part of the outer wall of the spring piece is fixedly connected to the inner wall of the transmission box, and the upper part of the outer wall of the spring piece is slidably connected to the inner wall of the transmission box.

[0008] Preferably, a spring is fixedly connected to the bottom outer ring of the card plate, and the bottom end of the spring is fixedly connected to the bottom of the inner wall of the transmission box.

[0009] Preferably, a transmission worm gear is fixedly connected to the middle left side of the servo motor, the left end of the transmission worm gear is movably connected to the left side of the inner wall of the regulating box, and a transmission worm wheel is meshed with the rear side of the outer wall of the transmission worm gear.

[0010] Preferably, a rotating shaft is fixedly connected to the inner wall of the transmission worm gear, the top end of the rotating shaft is movably connected to the top of the inner wall of the adjusting box, and the bottom end of the rotating shaft is fixedly connected to the middle of the top of the sphere.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a quick-closing mechanism with an electromagnet, permanent magnet, push rod, locking plate, spring, and other components. The controller activates the electromagnet to repel the permanent magnet, which in turn drives the push rod to slide upwards. The push rod then causes the locking plate to disengage. The compressed spring pushes the locking plate, push rod, and valve core upwards, achieving rapid valve closure. This allows some devices to stably close the internal channel of the valve core, facilitating timely closure of valves in heating networks and improving the device's timeliness and practicality.

[0012] 2. This utility model adjusts the flow rate of the valve body by adjusting the servo motor, transmission worm, transmission worm wheel, and rotating shaft in the mechanism. The controller starts the servo motor to drive the transmission worm to rotate in a limited position. The transmission worm meshes with and drives the transmission worm wheel, rotating shaft, and ball to rotate in a limited position, thereby realizing the flow rate adjustment of the valve body. This allows some devices to automatically control the size of the flow channel inside the valve body, making it easier to accurately control the flow rate of the fluid inside the valve body and improving the adjustability and practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 One embodiment provided by this utility model: A quick shut-off device for a heating network valve includes a valve body 11, a transmission box 12 fixedly connected to the bottom of the valve body 11, a ball 13 disposed inside the valve body 11, a valve core 14 inserted into the lower part of the ball 13, an adjustment box 15 fixedly connected to the top of the valve body 11, and a controller 16 fixedly connected to the front side of the adjustment box 15. The transmission box 12 is equipped with a quick-closing mechanism 2, which includes an electromagnet 21. The bottom of the outer wall of the electromagnet 21 is fixedly connected to the bottom of the transmission box 12. A permanent magnet 22 is located above the electromagnet 21. A push rod 23 is fixedly connected to the top center of the permanent magnet 22. The top of the push rod 23 is fixedly connected to the bottom center of the valve core 14. Through this design, the electromagnet 21 can attract or repel the permanent magnet 22, so that the permanent magnet 22 drives the push rod 23 and the valve core 14 to slide up and down. A retaining plate 24 is fixedly connected to the middle of the outer wall of the push rod 23. A spring is engaged on the outer wall of the retaining plate 24. The outer wall of the spring plate 25 is fixedly connected to the inner wall of the transmission box 12 at its lower part, and the outer wall of the spring plate 25 is slidably connected to the inner wall of the transmission box 12 at its upper part. Through this design, the clamping plate 24 is limited to the position below the spring plate 25, which facilitates the stable placement of the push rod 23 and the valve core 14. The bottom outer ring of the clamping plate 24 is fixedly connected to a spring 26, and the bottom end of the spring 26 is fixedly connected to the bottom of the inner wall of the transmission box 12. Through this design, the spring 26 applies an upward force to the clamping plate 24, the push rod 23 and the valve core 14, which facilitates the valve core 14 to stably close the internal channel of the ball 13.

[0017] The regulating box 15 is equipped with an regulating mechanism 3, which includes a servo motor 31. The left side of the servo motor 31 is fixedly connected to the right side of the regulating box 15. A transmission worm gear 32 is fixedly connected to the middle of the left side of the servo motor 31. The left end of the transmission worm gear 32 is movably connected to the left side of the inner wall of the regulating box 15. A transmission worm wheel 33 is meshed with the rear side of the outer wall of the transmission worm gear 32. Through this design, the servo motor 31 drives the transmission worm gear 32 to rotate in a limited position, so that the transmission worm gear 32 meshes with and drives the transmission worm wheel 33 to rotate. A rotating shaft 34 is fixedly connected to the inner wall of the transmission worm wheel 33. The top end of the rotating shaft 34 is movably connected to the top of the inner wall of the regulating box 15, and the bottom end of the rotating shaft 34 is fixedly connected to the middle of the top of the ball 13. Through this design, the transmission worm wheel 33 drives the rotating shaft 34 and the ball 13 to rotate in a limited position, thereby regulating the flow rate of the fluid inside the valve body 11.

[0018] Working principle: When the valve body 11 needs to be quickly shut off, the controller 16 first activates the electromagnet 21. The electromagnet 21 repels the permanent magnet 22, which in turn drives the push rod 23 to slide upward. The push rod 23 drives the locking plate 24 to disengage from the locking plate 24. The compressed spring 26 pushes the locking plate 24, the push rod 23, and the valve core 14 to slide upward, so that the valve core 14 stably shuts off the internal channel of the ball 13, thus realizing the quick shut-off operation of the valve body 11. Conversely, the controller 16 activates the electromagnet 21 to attract the permanent magnet 22, which drives the push rod 23 and the valve core 14 to slide downward. At the same time, the push rod 23 drives the locking plate 24 to lock under the locking plate 24, thus realizing the quick opening operation of the valve body 11.

[0019] When it is necessary to adjust the flow rate of valve body 11, the servo motor 31 is first started by the controller 16. The servo motor 31 drives the transmission worm gear 32 to rotate in a limited position. The transmission worm gear 32 meshes and drives the transmission worm wheel 33 to rotate. The transmission worm wheel 33 drives the rotating shaft 34 to rotate in a limited position. The rotating shaft 34 drives the ball 13 to rotate synchronously, thus realizing the flow rate adjustment operation of valve body 11. The operation ends here.

[0020] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
