Description

Technical Field

[0001] The present invention belongs to the technical field of valves, and in particular relates to a valve device with an ultrasonic flow detection function. Background Art

[0002] A valve device with ultrasonic flow detection is an industrial device that integrates flow measurement and process control. Its core lies in the integration of an ultrasonic flow detection module and a valve actuator. This module calculates fluid flow velocity by transmitting and receiving ultrasonic signals based on the time difference method or the Doppler effect. The time difference method is suitable for clean fluids and infers flow velocity by measuring the time difference between upstream and downstream flows. The existing technology uses multiple sets of bolts and nuts to connect the valve to the fixed pipe. Although this can ensure basic stability through multi-point force, it has significant drawbacks in practical applications. First, the multi-bolt structure requires the use of screwdrivers one by one for installation and disassembly. Especially in confined working conditions, the tool operation space is limited and time-consuming, which directly reduces equipment maintenance efficiency. Second, pulsation of the fluid medium or external vibration can easily cause micro-wear of the threaded pair. Metal fatigue can cause deformation of the thread profile, resulting in the risk of thread slippage failure. At the very least, this can cause the connection to become loose, and at worst, it can lead to medium leakage accidents. Summary of the Invention

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. Compared with traditional devices, the present invention realizes convenient installation of the connecting pipe inside the valve through the cooperation of the wedge and the spring. The self-locking characteristics of the wedge and the elastic compensation effect of the spring are combined to quickly achieve precise axial and radial positioning of the pipeline, avoiding sensor deviation caused by mechanical stress during installation and ensuring the stability of the ultrasonic signal transmission path. Secondly, the buffering performance of the spring can absorb fluid pressure fluctuations and pipeline deformation caused by thermal expansion and contraction, preventing signal interference caused by vibration or displacement. It is particularly suitable for scenarios where the time difference method has high precision requirements for propagation time difference.

[0015] 2. Compared with traditional devices, the present invention facilitates shock absorption of the arc support plate and valve through the cooperation between the slider and the shock-absorbing resistor, effectively ensuring measurement accuracy, and ensuring the stability of the ultrasonic signal transmission path by suppressing the influence of fluid pulsation and external mechanical vibration on the sensor, thereby improving the accuracy and repeatability of flow detection; secondly, the shock-absorbing design significantly extends the life of the equipment, can absorb the vibration energy of the connecting pipe and the valve, reduce metal fatigue, looseness of the connector and wear of the sealing surface, and thus reduce the risk of leakage, which is especially suitable for harsh working conditions such as high pressure or frequent opening and closing; in addition, the shock-absorbing structure also optimizes the fluid control performance, and by maintaining the stability of the fluid flow field, avoids the interference of turbulence on the particle / bubble reflection signal in the Doppler measurement, and enhances the reliability of the flow detection of fluid containing impurities.

[0016] 3. Compared with traditional devices, the present invention facilitates the support plate to support the connecting pipe through the cooperation between the sleeve block and the screw, thereby improving measurement stability, reducing structural stress risks, optimizing fluid dynamic conditions, enhancing the system's vibration resistance, and simplifying installation and maintenance processes, achieving multiple advantages. The connecting pipe support effectively reduces the mechanical vibration and pipe deformation caused by fluid flow, ensuring the stability of the ultrasonic signal transmission path, thereby ensuring the accuracy and repeatability of flow detection. At the same time, the rigid support plate disperses the pipe weight and fluid pressure load, preventing fatigue cracks and sealing failure at the connection between the valve and the connecting pipe, and extending the service life of the equipment; in addition, the stable connecting pipe support maintains the laminar state of the fluid flow field, reduces the interference of turbulence on Doppler measurement, and improves the reliability of flow detection of fluid containing impurities; when used near the vibration source, the support structure can also isolate external vibrations to avoid measurement errors caused by increased ultrasonic signal noise.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, an embodiment of the present invention provides a valve device with an ultrasonic flow detection function, including a support seat 1, an arc-shaped support plate 2 is movably installed inside the support seat 1, a valve 3 is fixedly installed on the top of the arc-shaped support plate 2, and a ball valve assembly is provided inside the valve 3;

[0027] A fixing groove 17 is provided inside the valve 3, and a second fixing block 22 is movably installed inside the fixing groove 17. A fixing groove 24 is provided inside the second fixing block 22, and a wedge block 23 is movably installed inside the fixing groove 24. A spring 9 is fixedly installed between the wedge block 23 and the second fixing block 22, and a connecting pipe 4 is fixedly installed at one end of the second fixing block 22.

[0028] Before using the ball valve assembly, the staff needs to install the connecting pipe 4 inside the valve 3, hold the connecting pipe 4 by hand, and slowly push the second fixing block 22 into the inside of the fixing groove 17 through the connecting pipe 4, squeeze the wedge 23 through the valve 3, and squeeze the spring 9 inside the fixing groove 24 through the wedge 23. When the second fixing block 22 completely enters the inside of the fixing groove 17, then, the spring 9 is squeezed inside the fixing groove 24, so that the wedge 23 enters the inside of the valve 3, and the connecting pipe 4 is limited and fixed by the wedge 23, thereby completing the fixed connection between the valve 3 and the connecting pipe 4.

[0029] The wedge 23 is squeezed, causing the wedge 23 to form radial pressure on the spring 9 in the fixing groove 24; when the second fixing block 22 is fully in place, the spring 9 is compressed and deformed, triggering the axial displacement of the wedge 23, so that it is embedded in the inner wall groove of the valve 3, and finally the axial positioning is achieved through the mechanical interlocking of the wedge 23 and the connecting pipe 4. This process converts the manual thrust into the synchronous action of the multi-stage limit mechanism through the cascade transmission of the wedge 23 and the elastic element, and completes the rigid connection between the valve 3 and the connecting pipe 4 without the need for additional tools. Compared with the traditional device, this device The connection pipe 4 is conveniently installed inside the valve 3 by cooperating with the wedge 23 and the spring 9. The self-locking property of the wedge 23 and the elastic compensation effect of the spring 9 are combined to quickly realize accurate axial and radial positioning of the pipeline, avoid sensor deviation caused by mechanical stress during installation, and ensure the stability of the ultrasonic signal transmission path; secondly, the buffering performance of the spring can absorb pipeline deformation caused by fluid pressure fluctuations and thermal expansion and contraction, and prevent signal interference caused by vibration or displacement. It is particularly suitable for scenarios with high precision requirements for propagation time difference in the time difference method.

[0030] Among them, a first fixed block 18 is fixedly installed at the bottom of the arc-shaped support plate 2, a shock-absorbing resistor 21 is fixedly installed inside the support seat 1, a slider 20 is movably installed on the outer surface of the shock-absorbing resistor 21, a second fixed block 22 is fixedly installed on the top of the slider 20, and a connecting rod 19 is hinged between the second fixed block 22 and the first fixed block 18.

[0031] The staff allows water to enter the interior of the valve 3 through the connecting pipe 4. At this time, the gravity of the water inside the valve 3 and the connecting pipe 4 squeezes the arc support plate 2, and then squeezes the first fixed block 18 through the arc support plate 2, and squeezes the connecting rod 19 through the first fixed block 18. Then, the slider 20 and the second fixed block 22 are moved synchronously through the connecting rod 19, and the shock-absorbing resistor 21 is squeezed through the second fixed block 22, thereby completing the shock absorption of the arc support plate 2 and the valve 3.

[0032] When water flows through the component connecting pipe 4 and enters the valve 3, the gravity of the water exerts pressure on the component arc-shaped support plate 2, and the pressure is transmitted to the first fixed block 18 through the arc-shaped support plate 2, and further squeezes the connecting rod 19; then, the displacement of the connecting rod 19 synchronously drives the slider 20 and the second fixed block 22 to move, and finally exerts an extrusion force on the shock-absorbing resistor 21 through the second fixed block 22, thereby forming a shock-absorbing effect on the component arc-shaped support plate 2 and the valve 3. Compared with the traditional device, the device facilitates the shock absorption of the arc-shaped support plate 2 and the valve 3 through the cooperation between the slider 20 and the shock-absorbing resistor 21, effectively ensuring the measurement accuracy, and suppressing The impact of fluid pulsation and external mechanical vibration on the sensor ensures the stability of the ultrasonic signal transmission path, thereby improving the accuracy and repeatability of flow detection; secondly, the shock-absorbing design significantly extends the life of the equipment, can absorb the vibration energy of the connecting pipe 4 and the valve 3, reduce metal fatigue, loosening of connectors and wear of sealing surfaces, and thus reduce the risk of leakage, which is especially suitable for harsh working conditions such as high pressure or frequent opening and closing; in addition, the shock-absorbing structure also optimizes the fluid control performance. By maintaining the stability of the fluid flow field, it avoids the interference of turbulence on the particle / bubble reflection signal in the Doppler measurement, and enhances the reliability of flow detection of fluids containing impurities.

[0033] The support base 1 has a fixed frame 13 fixedly mounted on its exterior. A slot 25 is defined within the fixed frame 13, and a sleeve 26 is movably mounted within the slot 25. A screw 27 is threadedly engaged with the sleeve 26, and one end of the screw 27 extends through the interior of the fixed frame 13. A ball valve 14 is fixedly mounted on one end of the screw 27. A rotating handle 28 is fixedly mounted on the exterior of the ball valve 14. The telescopic rod 12 is fixedly mounted on the top of the sleeve 26, and the support plate 11 is fixedly mounted on the output end of the telescopic rod 12.

[0034] After the staff completes the fixed connection of the connecting pipe 4 inside the valve 3, it is necessary to move the support plate 11 to the middle part to support the connecting pipe 4. By holding the rotating handle 28 and rotating it, the rotating handle 28 drives the screw 27 to rotate, and the screw 27 drives the inside of the sleeve block 26 to rotate, so that the sleeve block 26 moves inside the slide groove 25. The sleeve block 26 drives the telescopic rod 12 and the support plate 11 to move synchronously until the support plate 11 moves to the middle part of the connecting pipe 4, thereby completing the support of the connecting pipe 4 by the support plate 11.

[0035] After completing the fixed connection of the component connecting pipe 4 inside the valve 3, the component support plate 11 needs to be operated with intermediate support: the handheld component rotating handle 28 is rotated, and the component screw 27 is driven to rotate through the transmission structure, thereby driving the component sleeve 26 to make a linear displacement in the component slide 25, and synchronously pulling the component telescopic rod 12 and the support plate 11 to move axially until the support plate 11 accurately reaches the central axis position of the connecting pipe 4 to form a stable support, and finally completes the assembly of the rigid support structure of the key component connecting pipe 4. Compared with the traditional device, the device facilitates the support plate 11 to support the connecting pipe 4 through the cooperation between the sleeve 26 and the screw 27, thereby improving measurement stability, reducing structural stress risks, optimizing fluid dynamics conditions, and enhancing the system. The anti-vibration capability and simplified installation and maintenance process achieve multiple advantages. The support of the connecting pipe 4 effectively reduces the mechanical vibration and pipe deformation caused by fluid flow, ensures the stability of the ultrasonic signal transmission path, and thus guarantees the accuracy and repeatability of flow detection. At the same time, the rigid support plate 11 disperses the pipe weight and fluid pressure load, prevents fatigue cracks and sealing failure at the connection between the valve 3 and the connecting pipe 4, and extends the service life of the equipment; in addition, the stable support of the connecting pipe 4 maintains the laminar state of the fluid flow field, reduces the interference of turbulence on Doppler measurement, and improves the reliability of flow detection of fluid containing impurities; when used near the vibration source, the support structure can also isolate external vibration to avoid measurement errors caused by increased ultrasonic signal noise.

[0036] Among them, the ball valve assembly is movably installed inside the valve 3, and the ball valve assembly includes an internal ball valve 14 movably installed in the valve 3. A rotating shaft 5 is fixedly installed on the top of the ball valve 14, and one end of the rotating shaft 5 passes through the bottom of the valve 3. A fixed bracket 7 is fixedly installed on the outer surface of the valve 3, and a motor 6 is fixedly installed on the top of the fixed bracket 7, and the output end of the motor 6 is fixedly connected to the top of the rotating shaft 5. A sensor rod 15 is fixedly installed on the ball valve 14, and an ultrasonic sensor 16 is fixedly installed on the bottom of the sensor rod 15. A controller 8 is fixedly installed on the front of the fixed bracket 7.

[0037] After the staff has completely fixed the two connecting pipes 4 inside the valve 3, the flow control is then realized through the controller 8 integrating the ultrasonic sensor 16 and the ball valve 14 actuator. During operation, the ultrasonic sensor 16 emits an ultrasonic signal and uses the time difference method or the Doppler effect to detect the fluid flow rate. The sensor rod 15 ensures stable signal transmission. After the controller 8 receives the flow data, it calculates and outputs the control instruction through the PID algorithm to drive the motor 6 to operate. The motor 6 transmits the torque to the ball valve through the rotating shaft to adjust the valve opening, thereby accurately controlling the fluid on-off or flow size, forming a closed-loop control system to ensure that the flow is stable at the set value.

[0038] Among them, the fixing blocks 10 are fixedly installed around the outer side of the support base 1, and the interior of the fixing blocks 10 is provided with positioning holes 29.

[0039] Since the outer surface of the support seat 1 is fixedly installed with a fixing block 10, and a positioning hole 29 is opened inside the fixing block 10, the steel nail is held by hand and then slowly inserted into the positioning hole 29, and then the steel nail is completely hammered into the positioning hole 29 and the ground with a hammer. The fixing block 10 is limited and fixed inside the positioning hole 29 by the steel nail, and the support seat 1 is limited and fixed by the fixing block 10, thereby ensuring the stability of the support seat 1 during use.

[0040] A limiting groove 30 is provided inside the support base 1 , a limiting block 31 is movably installed inside the limiting groove 30 , and the inner side of the limiting block 31 is fixedly connected to the arc-shaped support plate 2 .

[0041] Since the inner side of the limit block 31 is fixedly connected to the arc support plate 2, the limit block 31 is squeezed by the arc support plate 2 to move up and down inside the limit groove 30, thereby ensuring the stability of the sensor rod 15 and the ultrasonic sensor 16 inside the valve 3 during use.

[0042] The sensor rods 15 and the ultrasonic sensors 16 are grouped in pairs, and there are two groups fixedly installed inside the ball valve 14 .

[0043] Since the sensor rods 15 and the ultrasonic sensors 16 are grouped in pairs, there are two groups fixedly installed inside the ball valve 14. Through the cooperation between the sensor rods 15 and the ultrasonic sensors 16, it is convenient to timely detect the internal water of the valve 3 and the connecting pipe 4, thereby improving the detection efficiency of the water flow.

[0044] The inner diameter of the chute 25 is equal to the outer diameter of the sleeve 26 , and the interior of the chute 25 has a smooth surface design.

[0045] Since the interior of the rotating handle 28 has a smooth design and the inner diameter of the slide groove 25 is equal to the outer diameter of the sleeve 26, it is convenient for the sleeve 26 to drive the support plate 11 and the telescopic rod 12 to move synchronously inside the slide groove 25, thereby ensuring the movement efficiency of the support plate 11 and the telescopic rod 12 in the fixed frame 13.

[0046] Working principle and usage process:

[0047] Before using the ball valve assembly, the staff needs to install the connecting pipe 4 inside the valve 3, hold the connecting pipe 4 by hand, and slowly push the second fixing block 22 into the inside of the fixing groove 17 through the connecting pipe 4, squeeze the wedge 23 through the valve 3, and squeeze the spring 9 inside the fixing groove 24 through the wedge 23. When the second fixing block 22 completely enters the inside of the fixing groove 17, then, the spring 9 is squeezed inside the fixing groove 24, so that the wedge 23 enters the inside of the valve 3, and the connecting pipe 4 is limited and fixed by the wedge 23, thereby completing the fixed connection between the valve 3 and the connecting pipe 4.

[0048] The staff allows water to enter the interior of the valve 3 through the connecting pipe 4. At this time, the gravity of the water inside the valve 3 and the connecting pipe 4 squeezes the arc support plate 2, and then squeezes the first fixed block 18 through the arc support plate 2, and squeezes the connecting rod 19 through the first fixed block 18. Then, the slider 20 and the second fixed block 22 are moved synchronously through the connecting rod 19, and the shock-absorbing resistor 21 is squeezed through the second fixed block 22, thereby completing the shock absorption of the arc support plate 2 and the valve 3.

[0049] After the staff completes the fixed connection of the connecting pipe 4 inside the valve 3, it is necessary to move the support plate 11 to the middle part to support the connecting pipe 4. By holding the rotating handle 28 and rotating it, the rotating handle 28 drives the screw 27 to rotate, and the screw 27 drives the inside of the sleeve block 26 to rotate, so that the sleeve block 26 moves inside the slide groove 25. The sleeve block 26 drives the telescopic rod 12 and the support plate 11 to move synchronously until the support plate 11 moves to the middle part of the connecting pipe 4, thereby completing the support of the connecting pipe 4 by the support plate 11.
