Technical Field

[0002] The oil pressure reducing valve is an important hydraulic control component used to control the liquid pressure in the hydraulic system. Traditional oil pressure reducing valves often use mechanical adjustment mechanisms to adjust the valve opening through manual knobs or simple mechanical linkages. This method is difficult to achieve high-precision pressure control. Most of them do not have automated adjustment functions and require manual intervention to adjust the valve. This is not only inefficient, but also prone to human errors. In addition, there is a lack of integrated electronic control systems, and remote monitoring and control are impossible, which limits its application in large-scale automated production systems.

[0003] To this end, we provide a high-precision oil pressure reducing valve to solve the above problems. Utility Model Content

[0025] Further description of the above structure includes: the fine-tuning valve body 11 and the coarse-tuning valve body 12 have different built-in valve core apertures, and the end faces of the fine-tuning valve body 11 and the coarse-tuning valve body 12 are sealed and connected, and the valve stem member is inserted into the valve stem sleeve 14 .

[0026] The output shafts of the motor 1 26 and the motor 2 25 are respectively connected with valve stems, and the valve stems are respectively connected to valve cores. The main bodies of the motor 1 26 and the motor 2 25 are fixed on the top of the motor kit 16, and the output shaft of the motor kit 16 is passed through the inside of the motor kit 16. The signal box 23 has a built-in processor and a wireless communication module. The processor is connected to the control panel 21, and the signal box 23 has a built-in independent power supply module.

[0027] The high-precision oil pressure reducing valve adopts a mechatronics design, which combines a precise mechanical structure with an advanced electronic control system to achieve fast and precise control of oil pressure. In addition, through the wireless communication function, it can be integrated into a larger automation system, supporting remote monitoring and control, and improving the flexibility and efficiency of the system.

[0028] Among them, in the segmented valve body 1, the fine-tuning valve body 11 is used to achieve fine adjustment of the oil pressure, and has a smaller valve core aperture so as to more accurately control the oil flow rate, thereby achieving the required oil pressure value. The coarse-adjusting valve body 12 is used to achieve preliminary adjustment of the oil pressure, and has a larger valve core aperture so as to quickly adjust the oil pressure to a value close to the set value. The connecting end 13 is used to connect the fine-tuning valve body 11 and the coarse-adjusting valve body 12 with the external oil pipe, and under the action of the sealing ring 17, the sealing between the valve bodies is ensured. The valve stem sleeve 14 is used to accommodate the valve stem member passing through it, and the valve stem member is connected to the valve core to control the flow of oil. The connecting plate 15 is fixed to the upper part of the valve stem sleeve 14, and is used as a mechanical interface of the entire device, which is convenient for connection with other components. The motor kit 16 is installed on the top of the connecting plate 15, and is used to fix the motor and guide the motor output shaft.

[0029] In the control component 2, motor 1 26 and motor 2 25 are used in conjunction with the fine-tuning valve body 11 and the coarse-tuning valve body 12 respectively. Motor 1 26 is connected to the valve stem in the fine-tuning valve body 11 through its output shaft, and motor 2 25 is connected to the valve stem in the coarse-tuning valve body 12 through its output shaft, thereby controlling the position of the valve core. A fixed plate 24 is fixed above motor 1 26 and motor 2 25, and is used as a basic platform for installing other electronic components. A signal box 23 is fixed on the fixed plate 24, and has a built-in processor and a wireless communication module. The processor is responsible for processing control logic and data transmission. The wireless communication module enables the device to receive remote commands or send status information. A control panel 21 is installed in front of the signal box 23, and is a human-computer interaction interface through which users can input control commands. A display screen 22 is embedded in the control panel 21, and is used to display the current operating status, setting parameters and other information. An independent power supply module supplies power to the signal box 23 and other electronic components to ensure the normal operation of the system.

[0030] When the oil pressure needs to be adjusted, the user first sets the target pressure value through the control panel 21. The control panel 21 transmits this information to the processor in the signal box 23. The processor calculates the valve core position that needs to be adjusted according to the set target pressure value, and sends a corresponding instruction to motor 1 26 or motor 2 25. Motor 1 26 or motor 2 25 rotates according to the instruction, drives the valve stem to move through the output shaft, and then changes the position of the valve core. The change in the valve core position causes the oil flow to change, thereby adjusting the oil pressure. During the whole process, the signal box 23 continuously monitors the actual oil pressure and compares it with the set value, and automatically adjusts the valve opening through the feedback loop to maintain a stable pressure level.
