Imported electric ball valve
Overview of imported electric ball valve
Electric ball valve is an important actuator in industrial automation control systems. The electric ball valve is a valve that rotates around the axis of the valve stem based on this movement of the valve disc. The change of the valve seat opening is directly proportional to the valve disc stroke. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of fluids. It is a pipeline pressure component for industrial automation process control.
The working principle of the imported electric ball valve
When there is no external opening signal (relay signal), the series electric ball valve remains fully closed and locked under the action of the working power supply. At this time, the indicating plate is fully closed. Indicates the position, and the electric indicating switch signal (relay signal) has no output. When the start electrical signal is added, the internal small relay acts, and the main motor rotates immediately. Under the action of the pinion switch on the rotating shaft, the motor stops rotating and remains electrically locked. At the same time, the electrical signal indicates that the switch is touched, and the switch signal is output. Make the indicator light in the control room have corresponding indication. At this time, the indicator panel is in the fully open indication position. On the contrary, when the opening electrical signal disappears, the motor immediately reverses. After a few seconds, under the action of the reverse limit switch, the motor stops. At this time, the valve position is fully closed and remains fully closed and electrically locked.
Edit Structural Features of Imported Electric Ball Valve
There is a locking hole in the fully open and fully closed position of the valve to prevent misoperation by non-staff members.
Set a step at the lower part of the valve stem to prevent the valve internal pressure from abnormally rising and falling out of the valve stem.
A fire-resistant sealing ring is installed between the ball and the valve seat. After the valve seat is burned, it still has a sealing effect.
The switch opens and closes quickly and flexibly, has a long life, is safe and reliable.
Pneumatic electric ball valves can be controlled remotely and centrally, and can meet the needs of computer program control.
