Description
technical field [0001] The invention relates to the technical field of an easy-to-operate valve actuator, in particular to an easy-to-operate valve actuator. Background technique [0002] With the rapid development of social economy, people need to use various valves, large and small, in daily life. Valves are used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. Pipeline accessories. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is the control component in the fluid delivery system, with the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief, etc. Function. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. There are various types an...
