1、 Overview of integrated explosion-proof switch type for electric actuator of dzwbz90 intelligent explosion-proof valve
According to the protection type, the multi turn electric device can be divided into outdoor type and flameproof type; According to the control mode, there are conventional type, integral type and integral adjustment type; Connection types: torque type, power station type and thrust type.
Dzw valve electric actuator, multi turn valve electric device, referred to as Z-type electric device for short, is the driving equipment for valve opening, closing or adjustment control. Z-type electric installation is applicable to gate valve, globe valve, diaphragm valve, plunger valve, throttle valve, sluice gate, etc. It can be used for rising stem valve and Non rising stem valve.
The performance of the dzw valve electric actuator of this product complies with the provisions of jb/t8528-1997 technical conditions for electric actuators of ordinary valves. The performance of flameproof type shall comply with "electrical equipment for explosive gas atmospheres B part 1: General requirements"), electrical equipment for explosive gas atmospheres B part 2: flameproof type "d") > and jb/t8529-1997 Technical conditions for electric devices of flameproof valves). This series of electric devices has the characteristics of complete functions, reliable performance, advanced control system, small volume, light weight, convenient use and maintenance, etc. it can implement remote control, centralized control and automatic control for valves. It is widely used in electric power, metallurgy, petroleum, chemical industry, papermaking, sewage treatment and other industries.
