Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, specifically to a wirelessly controlled valve assembly. Background Technology

[0002] As a core component in fluid control, valve body assemblies are widely used in industrial and civilian applications such as petrochemicals, municipal waterworks, and deep-sea resource extraction. Their core function is to precisely control the flow rate and on / off state of fluids through the coordinated movement of internal components such as the ball and stem, directly determining the operating efficiency and safety performance of the fluid system. With the increasing demands for industrial automation and remote maintenance, traditional valve body assemblies relying on wired transmission of control signals are gradually revealing drawbacks such as complex wiring, high maintenance costs, and susceptibility to damage in harsh environments. Valve body assemblies with wireless control capabilities, due to their advantages of eliminating the need for on-site wiring, flexible deployment, and compatibility with remote monitoring, have become an important direction for technological upgrading in the industry.

[0003] However, existing wireless control valve body components still face insurmountable technical bottlenecks in practical applications: First, signal transmission stability is insufficient. The valve body is mostly made of metal materials such as 304 and 316 stainless steel, which have a strong shielding effect on commonly used wireless frequency bands such as 2.4GHz. Existing components lack targeted signal penetration structure design, resulting in severe attenuation of wireless commands when penetrating the metal wall of the valve body, short communication distance, and high response delay. Furthermore, electromagnetic interference generated by equipment such as motors and frequency converters in industrial scenarios further leads to a wireless command loss rate of over 15%. Second, the protection performance is difficult to adapt to complex working conditions, and the sealing structure design at the component installation interface is simple. The existing components often use a single sealing ring, which is prone to failure due to medium corrosion and pressure fluctuations. This can cause fluid inside the valve body to seep into the wireless control module and cause a short circuit. In addition, the pressure and temperature resistance of the existing components are low, and they cannot withstand high pressure above 12MPa or a wide temperature range of -40℃ to 150℃. In deep-sea and high-temperature chemical environments, their service life is less than one year. Thirdly, there is a lack of control accuracy and safety assurance. The motor drive relies only on basic switch signals and lacks a real-time position feedback mechanism. The valve core opening adjustment error often exceeds ±1%, and there is no jamming fault protection structure. When the valve core is jammed by impurities, causing the motor to overload, it is easy to burn out the motor or damage the transmission components.

[0004] To address the core issues of existing wireless control valve components, namely "unstable signal transmission, weak protection performance, and insufficient control accuracy and safety," this invention proposes a wireless control valve component. This component overcomes the signal shielding limitations of metal valve bodies by creating a stepped annular window in the non-pressure-bearing area of ​​the valve body and embedding a signal transmission window. It employs a double-layer composite pressure-resistant shell with an inner PSS rigid support layer and an outer PEEK pressure-resistant protective layer, along with triangular reinforcements and elastic silicone filling, enhancing pressure resistance, vibration resistance, and sealing protection. Within the annular window, a wireless control component is integrated, comprising a motherboard, mounting plate, and ceramic patch antenna. The motherboard integrates an STM32H743 microprocessor, a DRV8833 motor driver chip, and a Hall position sensor, and is protected by a beryllium copper isolation cover to prevent electromagnetic interference. Stable linkage between the motherboard and the control motor is achieved via a Bluetooth receiver patch, ultimately realizing low-latency wireless command transmission, precise valve core opening and closing control, and long-term stable operation under complex working conditions.

[0006] To achieve the aforementioned objectives, this utility model provides the following technical solution: a wirelessly controlled valve assembly, comprising a valve body, the valve body being entirely made of stainless steel, and having a stepped annular window in its non-pressure-bearing area.

The wireless control component includes a motherboard, a mounting plate, and a ceramic patch antenna.

[0008] Preferably, the pressure-resistant outer shell has a double-layer composite structure, with the inner layer being a rigid support layer made of PSS and the outer layer being a pressure-resistant protective layer made of PEEK.

[0009] Preferably, a number of triangular reinforcing members are fixedly installed at equal intervals between the pressure-resistant protective layer and the rigid support layer, and elastic silicone for reinforcement and cushioning is filled between the rigid support layer and the pressure-resistant protective layer.

[0010] Preferably, the ceramic patch antenna is a rectangular ceramic patch structure adapted to 2.4GHz, and the top of the mounting disk has a rectangular mounting slot.

One end of the connecting wire is soldered to the electrode of the ceramic patch antenna, and the other end of the connecting wire is fixedly connected to the antenna endpoint on the top of the motherboard.

[0011] Preferably, the motherboard integrates an STM32H743 microprocessor, a DRV8833 motor driver chip, a Hall position sensor, and a wireless radio frequency circuit on its surface; the wireless radio frequency circuit area is covered by an isolation cover made of beryllium copper metal; the motherboard is electrically connected to the control motor via a Bluetooth receiver patch; the Bluetooth receiver patch is installed on the top of the control motor and electrically connected to it; and the outer layer of the isolation cover is covered with a copper mesh shielding layer.

[0012] Compared with the prior art, the present invention provides a wirelessly controlled valve assembly, which has the following advantages: 1. This wirelessly controlled valve assembly features a collaborative structure of wireless control and anti-interference to ensure stable and reliable signal transmission.

The response latency is controlled within 30ms, meeting the wireless control needs of conventional industrial scenarios such as petrochemicals and municipal waterworks.

[0013] 2. The wirelessly controlled valve assembly features a motor drive and precise control adaptation structure that ensures valve opening and closing accuracy and operational safety.

Combined with the Hall position sensors on the valve body, ball, and valve stem, it provides real-time feedback on the valve core position, achieving precise control with a valve core opening error of ≤±0.3%. At the same time, the overcurrent protection function of the DRV8833 and the ADC analog-to-digital conversion module of the STM32H743 can promptly identify valve core jamming faults and cut off the power supply to prevent motor burnout.

[0014] 3. The wirelessly controlled valve assembly features a robust protective structure that enhances environmental adaptability. The valve body is made of 304 / 316 stainless steel.

This makes it suitable for harsh working conditions such as high temperature, corrosion, and high pressure, extending the assembly's service life to over 3 years. Attached Figure Description

[0018] Please see Figure 1-4A wirelessly controlled valve assembly includes a valve body 1, which is made entirely of stainless steel. A stepped annular window 2 is provided in the non-pressure-bearing area of ​​the valve body 1.

[0020] Furthermore, the pressure-resistant outer shell 4 has a double-layer composite structure, with the inner layer being a rigid support layer 11 made of PSS and the outer layer being a pressure-resistant protective layer 12 made of PEEK.

[0021] Furthermore, several triangular reinforcing members 13 are fixedly installed at equal intervals between the pressure-resistant protective layer 12 and the rigid support layer 11, and elastic silicone for reinforcing cushioning is also filled between the rigid support layer 11 and the pressure-resistant protective layer 12.

[0022] Furthermore, the ceramic patch antenna 8 is a rectangular ceramic patch structure adapted to 2.4GHz, and a rectangular mounting slot is provided on the top of the mounting plate 7. The ceramic patch antenna 8 is attached to the mounting slot on the mounting plate 7 with thermally conductive adhesive, and the ceramic patch antenna 8 is connected to the motherboard 6 by a connecting wire 14. One end of the connecting wire 14 is soldered to the electrode of the ceramic patch antenna 8, and the other end of the connecting wire 14 is fixedly connected to the antenna endpoint on the top of the motherboard 6.

[0023] Furthermore, the motherboard 6 integrates an STM32H743 microprocessor, a DRV8833 motor driver chip, a Hall position sensor, and a wireless radio frequency circuit. The wireless radio frequency circuit area is covered by an isolation cover 15 made of beryllium copper. The motherboard 6 is electrically connected to the control motor 5 via a Bluetooth receiver patch 16. The Bluetooth receiver patch 16 is installed on the top of the control motor 5 and electrically connected to it. The outer layer of the isolation cover 15 is covered with a copper mesh shielding layer. Example

[0024] Example 1: The valve body 1 is made of 304 stainless steel. A signal transmission window 3 is embedded in the annular window 2 in the non-pressure-bearing area. The signal transmission window 3 and the annular window 2 are interference-fitted. Fluororubber sealing rings 10 are embedded in the two annular sealing grooves 9 on the outer wall. The contact surface is coated with silicone-based sealant to ensure a seal. Several triangular reinforcing members 13 are installed at equal intervals between the inner rigid support layer 11 and the outer pressure-resistant protective layer 12 of the pressure-resistant shell 4. The gaps are filled with elastic silicone to buffer vibration. In the wireless control component, the mounting plate 7 is embedded inside the annular window 2. The motherboard 6 inside it integrates an STM32H743 microprocessor, a DRV8833 motor driver chip, and a 2.4GHz wireless radio frequency chip. The circuitry, including the wireless RF circuit area, is covered with a beryllium copper shield 15 to resist electromagnetic interference. A ceramic patch antenna 8 is attached to the mounting slot at the top of the mounting plate 7 using thermally conductive adhesive. One end of the ceramic patch antenna 8 is soldered to an electrode via a connecting wire 14, and the other end is fixedly connected to the antenna endpoint at the top of the motherboard 6. The motherboard 6 is electrically connected to the control motor 5 via a Bluetooth receiver patch 16. The output shaft of the control motor 5 is connected to the ball valve stem inside the valve body 1 via a spline. The process of this component enabling wireless control of the valve opening and closing is as follows: An external control terminal sends a "valve open" wireless command. The command penetrates the metal wall of the valve body 1 through the signal transmission window 3 and is received by the wireless RF circuit on the motherboard 6. The wireless RF circuit decodes the command and transmits it to the STM32 microcontroller. The H743 microprocessor parses instructions and outputs a PWM control signal to the DRV8833 motor driver chip. The DRV8833 adjusts its output current according to the PWM signal, driving motor 5 to rotate forward. The motor's output shaft drives the ball valve stem inside valve body 1 to rotate synchronously via a spline. When the ball reaches the 90° fully open position, the magnetic mark on the valve stem triggers the Hall position sensor integrated into the main board 6. The sensor sends a stop signal to the STM32H743 microprocessor, which immediately cuts off the PWM output, stops power to the DRV8833 chip, and stops motor 5, completing the valve opening action. To close the valve, an external terminal sends a "close" command. The TM32H743 microprocessor controls the DRV8833 chip to output reverse current, driving the control motor 5 to reverse until the ball rotates back to the 0° fully closed position. The Hall sensor then triggers a stop, achieving the closing control. Through the instruction parsing and precise PWM control of the STM32H743 microprocessor, the stable current drive of the DRV8833 chip, and the low-latency transmission of the 2.4GHz wireless radio frequency circuit, wireless and automated control of valve opening and closing is achieved. The anti-interference design of the signal transmission window 3 and the isolation cover 15 ensures that electromagnetic interference from motors, frequency converters, and other equipment in industrial plants will not cause instruction loss. It is suitable for the fluid control needs of conventional industrial scenarios such as petrochemicals and municipal waterworks.
