Explosion-proof Electric Ball Valve Wiring Diagram Description And Control Method

Explosion-proof electric ball valve is a device that can prevent explosions in pipelines. That is, the electrical components comply with explosion-proof standards and can be used in situations requiring explosion-proof. It can not only be used in general oil, natural gas, environmental protection, water treatment, etc., including chemical industry In places with harsh working conditions such as industries and petroleum, the explosion-proof levels are such as common ExdIIBT4, ExdIICT5, ExdIICT6, etc. The explosion-proof electric ball valve uses 380V/220V/DC24V and other power sources as the driving power supply, and uses the switching signal or analog signal (4-20mA, 1-10V DC, 1-5V DC) as the control signal to move the valve to the required position. , to realize its automatic control. Different voltages and control forms have different wiring methods. Users need to understand and understand them in detail! The explosion-proof electric ball valve can withstand the explosion pressure of the internal explosive mixture and prevent the explosion of the surrounding explosive mixture. The shell is made of hard aluminum alloy, has strong corrosion resistance, and the protection level is IP67. The motor is a fully enclosed squirrel-cage motor with large torque, small inertia force, and an insulation level of F. It has a built-in overheating protection switch to prevent damage to the motor when the electric actuator is blocked and the motor overheats. It is also equipped with a handwheel design that can be used Operates during power outage to ensure safety and reliability.
