Technical Field

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Among them, electric hydraulic regulating valves with automatic adjustment functions have been widely used.

[0003] Prior art, such as: CN215371059U, a regulating valve that is easy to adjust the opening size, can limit the flow rate of the liquid by adding a flow limiting frame on the outside of the opening and closing part. First, the valve stem drives the opening and closing part to move so that the flow limiting holes at different heights can be interconnected, so that the liquid can flow out. The sealing slide on the opening and closing part cooperates with the slide groove on the flow limiting frame to limit the number of connected flow limiting holes, and the size of the opening is limited by the number of flow limiting holes. Then, the movement of the flow limiting frame can be driven by the rotation of the limiting screw, thereby reducing the restriction of the flow limiting holes to increase the size of the opening.

[0004] However, the device still has certain shortcomings when in use. The protection and stability of the device are poor. Not only is there no protective component on the outside, but it is also inconvenient to disassemble, which reduces its practicality. When adjusting the device, it is necessary to twist the knob to adjust the valve stem and the screw to control the flow through the opening and closing parts. Manual operation is required, which reduces work efficiency. The device cannot perform automatic detection.

[0005] Therefore, in order to solve the above problems, an electric hydraulic regulating valve with automatic regulating function is proposed. Utility Model Content
