Description

Technical Field

[0001] This utility model relates to the field of flow control valve technology, and in particular to a flow control valve for a remote mist sprayer. Background Technology

[0002] As a core piece of equipment for modern dust suppression, agricultural irrigation, and firefighting, the performance of remote-controlled fog cannons directly impacts environmental protection, agricultural production, and disaster prevention. In firefighting, spray flow rates in different areas need to be adjusted in real-time based on fire heat maps to achieve precise explosion suppression and cooling. In agriculture, soil moisture data must be used to automatically match crop water requirements, avoiding water hammer. In industrial dust suppression, spray parameters must be dynamically adjusted based on dust concentration feedback to achieve water conservation goals. Flow control valves, as the core actuators of fog cannon systems, directly determine the accuracy and response speed of fluid output. With the widespread adoption of IoT technology in industrial equipment, flow control valves also need to support remote, precise control, enabling intelligent linkage with total dust monitoring systems, video positioning systems, and automated management plans.

[0003] Currently, the flow control valves commonly used in fogging machines on the market have obvious limitations in terms of technology and structure, making it difficult to meet the needs of modern intelligent operations. Traditional manual valves or ordinary electric valves are insufficient in terms of remote control accuracy, especially in scenarios involving small flow rate adjustment. Therefore, further improvements are needed. Utility Model Content

[0008] A double sealing element is provided between the connecting guide rod and the valve body. The double sealing element includes a sealing ring, an elastic bellows, and a packing seal.

[0009] The connecting guide rod is equipped with a displacement monitoring module for real-time detection of valve core displacement;

[0010] The wireless control module has a built-in Bluetooth / Wi-Fi communication chip and microprocessor, which is used to receive remote commands and feed back valve position data.

[0011] Preferably, the adjusting threaded slider is provided with guide blocks and limiting grooves on both sides, the guide blocks are fixed on both sides of the adjusting threaded slider, and are slidably connected to the limiting grooves.

[0012] Preferably, the bottom of the conical seal is provided with a flow guide surface.

[0015] Preferably, the displacement monitoring module is a Hall sensor, which detects changes in magnetic flux and calculates the displacement value.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the remote mist sprayer flow control valve has the advantages of remote adjustment, high flow accuracy control, and good sealing, solving the problem of insufficient remote control accuracy of current flow valves, specifically:

[0017] 1. By setting up a wireless control module, users can send flow commands via mobile phone or console. After the communication chip receives the signal, the microprocessor analyzes the target opening and then controls the stepper motor to rotate to adjust the flow, which is highly flexible.

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

[0026] Please see Figures 1-3This utility model provides an embodiment of a remote mist sprayer flow control valve, comprising a valve body 1, a valve core drive unit 2, a precision valve core 3, a double seal 4, a displacement monitoring module 5, and a wireless control module 6. The valve body 1 includes an inlet 11, an outlet 12, and a regulating valve chamber 13, which is located in the middle of the inlet 11 and the outlet 12. The valve core drive unit 2 includes a stepper motor 21 and a planetary reducer 22. The planetary reducer 22 has a reduction ratio of 30:1 and a lead screw pitch of 0.5 to 5 mm, achieving a valve core displacement accuracy within 0.2 mm. A precision lead screw pair 23 is fixedly connected to the lower end of the planetary reducer 22. An adjusting threaded slider 24 is provided on the precision lead screw pair 23. Guide blocks 241 and limiting grooves 242 are provided on both sides of the adjusting threaded slider 24. The guide blocks 241 fix the adjusting threaded slider 24 on both sides and are slidably connected to the limiting grooves 242. A cone is provided at the head of the precision valve core 3. The valve body 1 has a conical seal 31 with a connecting guide rod 33 at its tail. The bottom of the conical seal 31 is provided with a flow guide surface 32. The conical seal 31 is in contact with the regulating valve cavity 13 to form a seal and isolate the liquid. The flow guide surface 32 allows the liquid to flow quickly through the regulating valve cavity 13. The surface of the conical seal 31 is covered with a polytetrafluoroethylene-ceramic composite coating. The composite coating can reduce the coefficient of friction and prevent particle adhesion. The connecting guide rod 33 is installed at the lower end of the adjusting threaded slider 24. A double seal 4 is provided between the connecting guide rod 33 and the valve body 1. The double seal 4 includes a sealing ring 41, an elastic bellows 42 and a packing seal 43. A displacement monitoring module 5 is provided on the connecting guide rod 33. The displacement monitoring module 5 is a Hall sensor. The sensor detects the change in magnetic flux and converts it into a displacement value for real-time detection of valve core displacement. The wireless control module 6 has a built-in Bluetooth / Wi-Fi communication chip and microprocessor for receiving remote commands and feeding back valve position data.

[0027] Working Principle: In use, this utility model, through the wireless control module 6, allows users to send flow commands via mobile phone or console. After the communication chip receives the signal, the microprocessor analyzes the target opening degree and controls the stepper motor 21 to rotate. After being reduced in speed by the planetary reducer 22, it drives the precision lead screw pair 23 to rotate, causing the adjusting threaded slider 24 to move the connecting guide rod 33 up and down. Finally, the flow is adjusted by adjusting the distance between the conical seal 31 and the regulating valve chamber 13, which is highly flexible. At the same time, the displacement monitoring module 5 monitors the displacement of the precision valve core 3 in a closed loop, achieving micro-compensation and high adjustment accuracy. By setting up double seals 4, the sealing ring 41 and the elastic bellows 42 isolate the liquid without hindering the movement of the connecting guide rod 33. The packing seal 43 provides secondary reinforcement and sealing, resulting in a good sealing effect.
