Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and automation, and in particular to an overpressure valve plate angle measuring device. Background Technology

[0002] Overpressure valves are critical safety devices widely used in aerospace, petrochemical, and industrial automation. Their primary function is to automatically open or close when system pressure exceeds a set range, maintaining system pressure stability and preventing equipment damage or accidents. The opening and closing status of the overpressure valve directly affects the safe operation of the system; therefore, measuring and monitoring its valve plate angle is crucial. To ensure accurate valve plate angle measurement, a high-precision angle measuring device is required. This device must not only accurately reflect the real-time position of the valve plate but also meet the requirements of convenient installation, easy operation, and stable reliability to adapt to complex industrial application environments.

[0003] In existing technologies, valve plate angle measurement mainly relies on mechanical angle indicators or traditional low-precision rotary encoders. These measurement methods typically employ mechanical transmission mechanisms such as gear drives, cam structures, or wire sensors to convert the valve plate's rotation angle into a readable value, which is then displayed via a pointer or electronic display. Gear drives utilize gear meshing to transmit angles, but are susceptible to backlash and wear, affecting measurement accuracy. Cam structures rely on mechanical contact for angle conversion, which is prone to mechanical fatigue after prolonged use, leading to measurement errors. While wire sensors offer a certain level of measurement accuracy, they are easily affected by external factors under high temperature and high pressure environments, resulting in unstable measurement data. Furthermore, these traditional measurement methods usually require complex debugging during installation, increasing installation time and maintenance costs. Additionally, accuracy degradation due to mechanical wear is unavoidable during long-term use.

[0004] Existing valve plate angle measuring devices often employ complex fixing methods, requiring multiple parts to work together. This not only increases installation time but also increases the risk of measurement errors due to loose parts. Furthermore, some devices have limited structural adaptability, necessitating additional adjustments or modifications when installed on valve bodies of different models or specifications, thus affecting the device's versatility and flexibility. Especially in high-precision measurement applications, installation errors can lead to measurement data deviations, impacting the safety and stability of the entire system. Therefore, optimizing the installation structure of angle measuring devices to improve installation efficiency and stability has become a pressing technological challenge. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an overpressure valve plate angle measuring device, which aims to improve the problem that the fixing method of some measuring devices in the existing valve plate angle measuring device is relatively complicated, requiring multiple parts to work together, which not only increases the installation time, but also easily leads to measurement errors due to loose parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an overpressure valve plate angle measuring device, including an angle indicator box.

The installation component is used to install the encoder. A coupling is provided below the encoder. A valve plate shaft is fixedly connected to the bottom of the coupling.

[0007] The mounting assembly includes an encoder mounting plate, the outer wall of which is fixedly connected to the lower surface of the encoder. A column is provided inside the encoder mounting plate, and upper and lower clamping plates are provided at the bottom of the column.

[0008] Furthermore, the upper and lower clamping plates are provided with clearance holes, and the upper and lower clamping plates are slidably connected with wing nuts. The lower surfaces of the upper and lower clamping plates are provided with knurled screws.

[0009] Furthermore, the switch, fuse, aviation plug socket, power supply, and reset button are all located on one side of the outer wall of the angle indicator box.

[0010] Furthermore, the columns are disposed on both sides of the outer wall of the encoder, and the columns are used to support the encoder.

[0011] Furthermore, the lower surface of the coupling is fixedly connected to the upper surface of the upper and lower clamping plates.

[0012] Furthermore, the columns are disposed on both sides of the outer wall of the coupling, and the columns are used to support the coupling.

[0013] Furthermore, the valve plate shaft is located below the upper and lower clamping plates.

[0014] Furthermore, the upper and lower clamping plates are disposed on the encoder, and the upper and lower clamping plates are used to support the column.

[0015] Furthermore, the wing nut is located in front of the encoder, and the wing nut is used to install the upper and lower clamping plates.

[0016] Furthermore, the knurled screw is disposed on one side of the wing nut.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the combined structure of the bracket assembly, upper and lower clamping plates, encoder mounting plate, and column enables the encoder to be stably installed and withstand the force generated by the rotation of the valve plate. During installation, only wing nuts and knurled screws are needed to fix the upper and lower clamping plates, which can quickly and firmly secure the device to the valve body. The design of the clearance hole improves the structural adaptability and makes the installation more flexible. The application of the coupling simplifies the connection between the encoder shaft and the valve plate shaft, ensuring precise synchronization between the two, reducing adjustment steps, improving installation accuracy, shortening installation time, and reducing human error.

[0019] 2. In this utility model, a high-precision rotary encoder with 36,000 pulses and a measurement accuracy of up to 0.01° is used. Combined with an angle display, the valve plate angle can be displayed in real time to ensure accurate measurement. The angle indicator box integrates functions such as switch, fuse, aviation plug socket, and power supply, which simplifies system operation, facilitates real-time status monitoring, reduces the occurrence of faults, and improves testing efficiency. Operators do not need to manually measure or estimate the angle; they can directly read the data from the angle indicator box to complete the monitoring, which greatly improves work efficiency and measurement accuracy, and ensures the safe and stable operation of the overpressure valve.

[0028] Reference Figure 1 - Figure 5 An embodiment of this utility model provides an overpressure valve plate angle measuring device, including an angle indicator box 1. The operation panel of the angle indicator box 1 is provided with an angle display instrument 2. A switch 3, a fuse 4, a flight plug socket 5, a power supply 6 and a reset button 7 are arranged around the angle display instrument 2 in sequence. The flight plug socket 5 is matched with a connecting cable 8. One end of the connecting cable 8 is fixedly connected to an encoder 9. The lower surface of the encoder 9 is provided with a mounting component for mounting the encoder 9. A coupling 11 is provided below the encoder 9. The bottom of the coupling 11 is fixedly connected to a valve plate shaft 12.

[0029] The mounting assembly includes an encoder mounting plate 13, the outer wall of which is fixedly connected to the lower surface of the encoder 9. An internal column 14 is provided in the encoder mounting plate 13, and upper and lower clamping plates 15 are provided at the bottom of the column 14.

[0030] Specifically, the installation process is simple and quick, mainly relying on the bracket assembly, upper and lower clamping plates 15, encoder mounting plate 13, column 14, and coupling 11 for a stable connection, ensuring that the equipment can be firmly fixed to the valve body, reducing human error and improving installation efficiency. First, the rotary encoder 9 is installed onto the column 14 through the encoder mounting plate 13. The column 14 is located on both sides of the encoder 9 to provide stable support and prevent displacement caused by vibration or external force. Next, the upper and lower clamping plates 15 are fixed to the valve body by wing nuts 10 and knurled screws 17. The wing nuts 10 are located in front of the encoder 9 and serve to fix the clamping plates, while the knurled screws 17... To further enhance the tightness of the clamping plates and ensure that the equipment does not loosen, the upper and lower clamping plates 15 are also equipped with clearance holes 16 to adapt to the installation requirements of different valve bodies, thereby improving the compatibility and installation flexibility of the equipment. After installation, the encoder 9 is connected to the valve plate shaft 12 through the coupling 11 to ensure synchronous rotation of the two and ensure the accuracy of the measurement data. During the installation process, the coupling 11 is tightened first to ensure that the encoder shaft and the valve plate shaft 12 are aligned, and then the upper and lower clamping plates 15 are tightened to fix the entire support system. Finally, the connecting cable 8 is connected to the angle indicator box 1, and the power supply and signal transmission configuration is completed. The entire installation process is simple, efficient and stable.

[0031] Reference Figure 1 , Figure 2 and Figure 5 The upper and lower clamping plates 15 have clearance holes 16 inside, and wing nuts 10 are slidably connected inside the upper and lower clamping plates 15. Knurled screws 17 are provided on the lower surface of the upper and lower clamping plates 15. Switches 3, fuses 4, aviation connectors 5, power supplies 6, and reset buttons 7 are all located on the operation panel of the angle indicator box 1. Columns 14 are located on both sides of the outer wall of the encoder 9, and are used to support the encoder 9. The lower surface of the coupling 11 is fixedly connected to the upper surface of the upper and lower clamping plates 15. Columns 14 are located on both sides of the outer wall of the coupling 11, and are used to support the coupling 11. Valve plate shaft 12 is located below the upper and lower clamping plates 15. The upper and lower clamping plates 15 are located on the encoder 9 and are used to support the columns 14. Wing nuts 10 are located in front of the encoder 9 and are used to install the upper and lower clamping plates 15. Knurled screws 17 are located on one side of the wing nuts 10.

[0032] Specifically, the rotary encoder 9 boasts a high resolution of 36,000 pulses, enabling it to measure with an accuracy of up to 0.01°. This allows for precise capture of valve plate angle changes, avoiding errors inherent in traditional measurement methods. The encoder 9 transmits measurement data to the angle display 2 via the connecting cable 8. This display has a resolution of "0.000", ensuring that operators can directly read accurate valve plate angle data without additional calculations, thus improving the intuitiveness and accuracy of the measurement. The angle indicator box 1's control panel includes a switch 3, a fuse 4, a power connector 5, a power supply 6, and a reset button 7, allowing operators to easily control the device's status. The system monitors the equipment's operation during testing to prevent measurement errors caused by malfunctions or abnormal signals. During testing, the operator first adjusts the valve plate to the fully closed position (0°) and presses the reset button 7 to zero the angle display 2, displaying "0.00". As the valve plate rotates, the encoder 9 accurately tracks its angle changes and updates the displayed data in real time, ensuring that the operator can always monitor the valve plate's opening status. This design greatly improves the convenience and accuracy of testing, eliminating the need for manual measurement or angle estimation, reducing human error, improving overall work efficiency, and ensuring the safety and reliability of the overpressure valve system.

[0033] Working principle: First, the rotary encoder 9 has 36,000 pulses and a resolution of up to 0.01°. It is connected to the valve plate shaft 12 through the coupling 11 to ensure that the encoder 9 rotates synchronously when the valve plate rotates. The angle signal collected by the encoder 9 is transmitted to the angle display instrument 2 through the connecting cable 8. The display instrument has a resolution of "0.000" and can display the current angle in real time when the valve plate rotates. The angle indicator box 1 has a switch 3, a fuse 4, a flight plug socket 5, a power supply 6, and a reset button 7 on its operation panel to facilitate the operation and status monitoring of the system.

[0034] In addition, during installation, the encoder 9 is first fixed to the bracket via the encoder mounting plate 13 and the column 14. The column 14 is located on both sides of the encoder 9 to provide stable support. The upper and lower clamping plates 15 are fixed to the valve body via wing nuts 10 and knurled screws 17. The wing nuts 10 are located in front of the encoder 9 for clamping, and the knurled screws 17 are used to further tighten the upper and lower clamping plates 15. The clamping plates are also provided with clearance holes 16 to meet structural clearance requirements. After the bracket is fixed, the encoder 9 shaft and the valve plate shaft 12 are connected using the coupling 11. First, the coupling 11 is tightened to ensure the synchronization of the encoder and the valve shaft, and then the upper and lower clamping plates 15 are tightened to ensure that the bracket is firmly installed. Finally, the connecting cable 8 is connected to the angle indicator box 1, and the valve plate is adjusted to the fully closed position of 0°. The reset button 7 is pressed to zero the angle display 2, and the indicator box displays "0.00". During the operation of the valve plate, the system will display the valve plate angle in real time and accurately to ensure the safe and efficient operation of the overpressure valve.
