Description

Technical Field

[0001] This utility model belongs to the technical field of oxygen pressure workshop regulating valves, and in particular relates to an oxygen pressure workshop regulating valve that utilizes linear stroke to angular stroke conversion. Background Technology

[0002] A control valve, also known as a regulating valve, receives control signals from a control unit and uses power to change the flow rate of fluid. A control valve generally consists of an actuator and a valve body. Based on the power source of its actuator, control valves can be classified into three types: pneumatic control valves, electric control valves, and hydraulic control valves. Additionally, based on their function and characteristics, they can be classified into three types: linear characteristic, equal percentage characteristic, and parabolic characteristic.

[0003] Due to the harsh environment in the oxygen pressure workshop, the original regulating valves were linear valves, which often resulted in severe corrosion of the valve core and corrosion and detachment of the valve stem, rendering them unable to perform their regulating function and control the pipeline flow.

[0004] To address these issues, we provide an oxygen pressure control valve that utilizes a linear-to-angular stroke conversion mechanism. Utility Model Content
