Description of the working principle and structure description of the electric ball valve

1, the working principle of electric ball valve Electric ball valve, as the name suggests: is to use the power to drive the ball valve. The electric ball valve is mainly made up of a high-precision electric actuator and a high-quality ball valve body connected to the bracket through a coupling. The voltage of the actuator is mainly 220V, 380V, 24V, and the control mode is switch type and regulation type. The electric switch ball valve is a valve with a switch quantity control, and the switch signal of the actuator receiving system directly controls the opening and closing action of the valve. The electric regulating ball valve is an analog-controlled valve. The actuator receives the 4-20 mA analog signal from the system and controls the 0-90 degree of the electric ball valve through 4-20 mA.
2. Structure of electric ball valve Electric ball valve is mainly divided into electric adjustment ball valve and electric switch ball valve. The components of the ball valve are: valve body, valve seat, sealing ring, valve stem, sphere and other components. The main materials are carbon steel and stainless steel. Special steel material such as chrome molybdenum steel. The main pressure is divided into 1.6-32 MPa.
