Description

[Technical Field] This utility model relates to the field of pressure regulating valve technology, and in particular to a high-precision intelligent pressure regulating valve. [Background Technology] Pressure regulating valves are commonly used industrial devices, primarily used to control the pressure of fluid media and maintain it stable within a certain range. They are widely used in petroleum, chemical, power, metallurgical, and pharmaceutical industries, serving to regulate media flow and protect equipment and pipelines. Specifically, the functions of pressure regulating valves include the following: Pressure regulation: Pressure regulating valves can automatically adjust the pressure in the system as needed to ensure stable operation of the medium within the normal range; Flow control: Pressure regulating valves control the flow rate of the medium by adjusting the valve opening to meet process requirements and equipment operation needs; Safety protection: In equipment and pipelines, excessive pressure of the medium may lead to explosions or other accidents. The presence of pressure regulating valves can prevent such problems from occurring, ensuring the safety of equipment and personnel; Equipment protection: Pressure regulating valves can effectively reduce vibration and impact caused by pressure changes in the system, prevent equipment wear, leakage and other problems, and extend the service life of the equipment.

[0001] Currently, most pressure regulating valves are still manually adjustable, relying mainly on mechanical structures and manual adjustment to regulate and control pressure. Their core drawback is that the adjustment accuracy is limited by the mechanical structure, which cannot meet the high precision requirements. They cannot automatically compensate for pressure fluctuations, lack real-time monitoring functions, and are relatively complex to maintain.

[0002] The main components of a mechanical pressure regulating valve include a valve core, an adjusting spring, and a rotating wheel. The adjustment process involves the rotating wheel pressing down on the adjusting spring, which in turn raises the valve core to achieve pressure regulation. In a manual regulating valve, the rotating wheel has a rotation angle scale position during the adjustment process. It can only be pressed and locked at the scale angle position. Due to the limitation of the precision of the mechanical scale angle, 360° stepless adjustment cannot be achieved, and the adjustment precision cannot meet the precision adjustment required by fields such as tension control systems and pneumatic positioning systems, which require a jump accuracy of 0.1% or higher. Therefore, it is necessary to improve the high-precision control and intelligent adjustment performance of the pressure regulating valve. [Summary of the Invention] This invention addresses the above-mentioned problems by proposing a high-precision intelligent pressure regulating valve. The valve is equipped with a stepper motor and a digital display pressure gauge. It can not only achieve high-precision adjustment by precisely adjusting the rise and fall of the valve core through the stepper motor, but also monitor the adjustment effect in real time through the digital display pressure gauge. The system feedback is intuitive and rapid, providing real-time feedback data for automatic pressure compensation and abnormal situation monitoring at the back end. It is also suitable for integration into an intelligent control system to improve the overall system performance.

[0003] An intelligent pressure regulating valve includes a housing, a compression spring, and a valve core. The valve core is driven by the spring pressing down inside the housing. The valve core is characterized in that a stepper motor is provided inside the housing, which drives a transmission threaded rod to rotate. The transmission threaded rod meshes with a top ball threaded rod, and the rotation of the transmission threaded rod drives the top ball threaded rod. A top plate and a compression spring are provided below the top ball threaded rod. The top plate presses against the compression spring, causing the valve core to move. A digital pressure gauge is provided on the side of the valve core.

[0004] The pressure regulating valve is also equipped with a motor mounting seat, a valve core mounting seat, and a bearing. A valve core mounting seat is provided on the outside of the valve core, and a motor mounting seat is provided outside the valve core mounting seat. A bearing is provided between the motor mounting seat and the transmission threaded rod.

[0005] The upper end of the transmission threaded rod is connected to the drive shaft of the stepper motor, and the lower end engages with the top ball threaded rod.

[0006] The inner wall of the transmission threaded rod has internal threads, while the ball threaded rod has external threads that match the internal threads of the transmission threaded rod.

[0007] The motor is a closed-loop stepper motor.

[0008] The intelligent pressure regulating valve involved in this utility model is equipped with a stepper motor and a digital display pressure gauge.

The system feedback is intuitive and rapid, providing real-time feedback data for automatic pressure compensation and abnormal situation monitoring at the back end. It is suitable for integration into intelligent control system to improve the overall system performance.
