[0002] The oil pressure valve, also known as a process valve, is a fully open and fully closed valve, which requires to be unobstructed when opened and airtight when closed. It is mainly used to switch the flow direction of gas or liquid, realize the conversion connection of stages, and form a cyclic gas-making or liquid-making system. The existing oil pressure valves have been widely used in industrial production, construction equipment and many other fields;

[0003] However, most of these existing oil pressure valves do not have the function of automatic adjustment. Most of the existing oil pressure valves need to be manually adjusted, and the oil pressure cannot be adjusted in real time according to actual needs, resulting in poor control effect and slow response speed. Due to relying on mechanical devices or manual operations, the response speed of the existing oil pressure valves is slow when adjusting the oil pressure, and they cannot meet some working conditions that require rapid response. Therefore, we propose an intelligent control oil pressure valve to solve the above problems. Content of the Utility Model
