Open type electric gate valve adopts floating valve plate. The compression mechanism adopts gear ring, gear, trapezoidal thread, lever screw pair and synchronous bidirectional compression. The advantages of synchronous compression of left and right trapezoidal thread rods are: small starting torque , good self-searching of lever screw pair, reliable sealing. Plate movement adopts pin tooth drive mechanism: ash not easy to accumulated and can satisfy usage under sever working conditions of more dust and worse lubrication.
◆ Explosion-proof control cabinet to realize field control and remote PLC system connection control with distance more than 10 meters.
◆ Reasonable and simple structure, easy manufacture, lower cost and good performance. Enjoying advantages of no blocking, no leakage, convenient repair and maintenance, good accuracy of discharge quantity, high working efficiency, long service life.
