The electric angle control valve is mainly composed of an electric actuator and an angle valve body. The valve core is a single guide structure. It has the characteristics of simple flow path, small resistance, large flow and high adjustment accuracy. The electric angle control valve is suitable for controlling high viscosity. Medium, fluid and mud containing particles, 90-degree elbow joints, flashing fluid, etc., can avoid coking and clogging, and the valve body has no dead angle, which is convenient for self-cleaning and cleaning, and is widely used.
Electric angle control valve performance characteristics:
The electric angle control valve automatically controls the opening of the valve according to the signal of the adjustment part, so as to achieve the adjustment of medium flow, pressure and liquid level.
The working principle of electric angle control valve:
The electric angle control valve usually adopts the flow direction of the open type (that is, the bottom enters and the side exits), and the electric actuator contains the feeding function, which accepts a unified 4-20mA or 1-5V·DC standard signal, and converts the current signal into phase. The corresponding linear displacement automatically controls the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline.
Dynamic diagram of working principle of electric angle control valve:
Electric angle control valve has the advantages of small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. Electric angle control valves are widely used to precisely control gas, liquid and other media, and process parameters such as pressure, flow, temperature, and liquid level are kept at a given value. The electric angle control valve is especially suitable for the adjustment of high viscosity, suspended solids and granular substances with small pressure difference between the front and back of the valve that allows small leakage. It can avoid coking and blockage, and is convenient for self-cleaning and cleaning.
