Precautions for using the electric switch butterfly valve

Electric switch butterfly valve is the best valve body used in electrical and chemical pipelines. If unsuitable butterfly valve is selected, it will not only cut off fluids well, but it will also cause bad influence on people's life and even life safety. Therefore, the use of electric valves must be emphasized in the design of pipeline projects.
With the continuous improvement of the level of industrial automation, the demand for electric switch butterfly valves is increasing, and the control requirements for it are also more stringent. Therefore, the design of the electric butterfly valve in the automatic control system is also advancing with the times. For the consideration of this part of the overall control, the control type of the electric valve should be emphasized.
The electric switch butterfly valve has the advantages of convenient and quick opening and closing, time and labor saving, simple design, portable light, good sealing, and good adjustment function, but it can not use the pressure conditions and the working temperature range.
The use of electric butterfly valve must pay attention to the parameters of the pipeline, but also need the external environmental conditions of the pipeline, because the electric valve is installed inside the electric device, which belongs to the mechanical and electrical equipment, the use of equipment is susceptible to the external environment.
In general, electric switch butterfly valves require special attention to use in the following environmental conditions:
1. Outdoor application of devices or protective devices indoors;
2. Outdoor equipment in the outdoor environment, this situation will be eroded by strong wind, dust, rain, and sunlight;
3, near the flammable and explosive gas or dust environment;
4. The geographical location is in a wet, dry and hot environment;
5, the medium temperature is above 450 °C;
6, the ambient temperature is below -20 degrees Celsius;
7, easily flooded or soaked in water;
8, will be affected by the surrounding radioactive material, such as nuclear power plants;
9, at the seaside susceptible to salt spray, moldy fungi, more humid or high humidity environment, such as ships or dock terminals;
10, there is a long time around the vibration of the motor, etc. or is easy to catch fire and fire occasions;
When the electric switch butterfly valve has to be used in these environments, its electric device structure, materials used and protective measures are very different. Therefore, it is necessary to select a corresponding suitable device by referring to the difference in the above working environment. If you choose not to consider it properly, it will not only affect the normal use of the pipeline, but it will even cause economic losses and casualties and other unfavorable consequences.
