In addition to paying attention to the pipeline parameters, the explosion-proof electric butterfly valve also needs to pay attention to its use environment. Since the valve electric device in the explosion-proof electric butterfly valve is an electromechanical device, its use state is very important in the environment.
Under normal conditions, explosion-proof electric butterfly valves should pay special attention to the following environments.
Explosion-proof electric butterfly valve wiring
1 indoor unit or protected outdoor application;
2 outdoor open-air installations, with wind, sand, rain, sun and other erosion;
3 has a flammable, explosive gas or dust environment;
4 wet tropical, dry tropical environment;
5 pipe medium temperature up to 450 ° C or more;
6 ambient temperature is below -20 ° C;
7 vulnerable to flooding or immersion in water; 8 environment with radioactive materials (nuclear power stations and radioactive material testing devices);
9 on board or dock dock (with salt spray, mold, moisture);
10 occasions with severe vibration; occasions prone to fire;
For the explosion-proof electric actuated butterfly valve in the above environment, the structure, materials and protection methods of the electric device are different. Therefore, the corresponding explosion-proof electric butterfly valve products should be selected according to the corresponding environment.
