Do you know the Performance and Usage of Electric Ball Valve?

What is the basis for the selection of electric ball valve?

First, it is the control element, which is very widely used in the application of fluid pipeline systems, and has many uses. It has very good effects on controlling flow, pressure, backflow, etc. Since the quality of the electric ball valve has a great influence on the safety of the pipeline, when choosing an electric ball valve, it must be selected according to certain steps and basis.

Second, clarify the diameter of the pipeline of your company, know what diameter and connection method you need to choose the electric ball valve.

3. According to the needs of the pipeline, first determine some common parameters of the electric ball valve, such as the discharge capacity, the allowable flow resistance, the diameter of the valve seat hole, etc. If these parameters are not selected correctly, the effect of the electric ball valve to control the flow, will be greatly discounted.

4. According to the working temperature of the pipeline, choose the appropriate material. Of course, the working pressure of the pipeline should also be taken into consideration.

In addition, it should be reminded that do not rush to choose products, you must first understand what are the popular electric ball valve products and how they perform, and the best way to understand these is to contact a number of electric ball valve manufacturers and let them Provide product catalogs, styles, etc., and shop around to choose the most cost-effective products.

In addition to paying attention to the pipeline parameters, the electric valve should also pay special attention to the environmental conditions of its duty. Since the electric device in the electric valve is an electromechanical device, its duty state is greatly affected by its duty environment.

Under normal conditions, special attention should be paid to the use of electric ball valves in the following environments

1. Indoor installations or outdoor applications with protective methods;

2. Outdoor open-air installations, eroded by wind, sand, rain, sunlight, etc.;

3. With flammable, explosive gas or dust environment;

4. Environment in wet tropics and dry tropics;

5. The temperature of the pipeline medium is as high as 450℃ or more;

6. The ambient temperature is below -20℃;

7. Easily flooded or immersed in water;

8. Environment with radioactive substances (nuclear power plants and radioactive substances test equipment);

9. Environment on ships or docks (with salt spray, mold, humidity);

10. Occasions with severe vibration; occasions prone to fire;

For the electric ball valve in the above environment, the electric device structure, material and protection method are all different. Therefore, the corresponding valve electric device should be selected according to the above-mentioned obligation environment.

Functional requirements of electric ball valve

According to the engineering control requirements, for the electric ball valve, its control function is completed by the electric device. The purpose of applying electric ball valve is to complete non-manual electrical control or computer control for the opening, closing and adjustment of the valve. The current application of electric devices is not just for diligent labor. Since the functions and quality of products of different manufacturers are quite different, the selection of electric devices and the selection of valves are equally important to the project.

Electric control of electric ball valve

Due to the continuous improvement of the requirements of industrial automation level, on the one hand, the application of electric valves is increasing, and on the other hand, the control requirements for electric valves are also getting higher and higher and more complicated. Therefore, the design of electric valve in electrical control is always updated. With the continuous improvement of the use requirements and the popularization and application of Shanghai Mingbao valves and computers, new and diverse electrical control methods will always appear.

For the scrutiny of the overall control of the electric valve, attention should be paid to the selection of the control method of the electric valve. For example, according to the needs of the project, whether to use the centralized control method or the single control method, whether to link with other equipment, sequence control or computer sequence control, etc., the control principles are different. The valve electric device manufacturer's sample only gives the standard electrical control principle, so the application department should make technical disclosure with the electric device consumer to clarify the technical requirements.
