How Does A Electric Fluorine-Linead Ball Valve Work?
Overview of Electric Fluorine-lined Ball Valve
The electric fluorine-lined ball valve uses fluorine plastic as the lining and is equipped with a new type of ball structure with a rod. In addition, its unique elastic lip seal seat structure gives it all the advantages of ordinary ball valves. It can have high sealing performance and low operating torque in a large pressure difference and a large temperature difference range. It can be used for switching or regulation. This product is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines and can work well in various strong corrosive media such as acids, alkalis, and salts. The full-bore valve provides the maximum flow and can be used for sweeping, cleaning, or isolating the pipeline for transportation.
What is an electric fluorine-lined ball valve used for?
Product application areas
The product is widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of severely corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia, and other highly corrosive media.
Selection in pipeline engineering
In pipeline engineering, the correct selection of electric fluorine-lined ball valves is one of the guaranteed conditions for meeting application requirements. If the electric fluorine-lined ball valve used is not properly selected, it will not only affect the application but also bring adverse consequences or serious losses. Therefore, the electric fluorine-lined ball valve double-stage worm gearbox should be correctly selected in the design of pipeline engineering.
Duty environment of electric fluorine-lined ball valves
In addition to paying attention to pipeline parameters, electric fluorine-lined ball valves should also pay special attention to their duty environment conditions. Since the electric device in the electric fluorine-lined ball valve is an electromechanical device, its duty state is greatly affected by its duty environment.
- Under normal circumstances, the electric fluorine-lined ball valve is in the following environments:
- Indoor installation or outdoor application with protection
- Outdoor installation is subject to erosion by wind, sand, rain, dew, sunlight, etc.
- Environment with flammable and explosive gas or dust
- Environment in humid tropical and dry tropical areas
- Pipeline medium temperature up to 150℃ or above
- Ambient temperature below -20℃
- Easy to be flooded or immersed in water
- Environment with radioactive materials (nuclear power plants and radioactive material test equipment)
- Environment on ships or docks (with salt spray, mold, humidity)
- Occasions with severe vibration; Occasions prone to fire
For the electric fluorine-lined ball valves in the above environments, the electric device structure, material, and protection methods are different. Therefore, the corresponding fluorine-lined ball valve electric device should be selected according to the above obligation environment.
What are the functional requirements for electric fluorine-lined ball valves?
According to the engineering control requirements, the control function of the electric fluorine-lined ball valve is completed by the electric device. The purpose of using the electric fluorine-lined ball valve is to complete the non-manual electrical control or computer control of the valve opening, closing, and adjustment linkage. The current application of electric devices is not just for saving manpower. Since the functions and quality of products from different manufacturers vary greatly, the selection of electric devices and the selection of the matching fluorine-lined ball valve are equally important to the project.
How to achieve electrical control of an electric fluorine-lined ball valve?
As the requirements for industrial automation levels are constantly increasing, on the one hand, the application of electric fluorine-lined ball valves is increasing, and on the other hand, the control requirements for electric fluorine-lined ball valves are becoming higher and higher and more complex. Therefore, the design of electric fluorine-lined ball valves in electrical control is also constantly updated. With the improvement of science and technology and the popularization and application of computers, new and diverse electrical control methods will continue to appear. When considering the overall control of fluorine-lined electric ball valves, attention should be paid to selecting the control method of electric fluorine-lined ball valves. For example, according to the needs of the project, whether to use centralized control or single-unit control, whether to link with other equipment, sequential control or computer sequential control, etc., the control principles are different. The sample of the electric device manufacturer of the fluorine-lined ball valve only gives the standard electrical control principle, so the application department should conduct a technical briefing with the electric device consumer to clarify the technical requirements.
In addition, when selecting an electric fluorine-lined ball valve, it should be considered whether to purchase an electric fluorine-lined ball valve controller. Due to the general situation, the controller needs to be purchased separately. In most cases, when using single-unit control, it is necessary to purchase a controller, because purchasing a controller is more convenient and cheaper than designing and manufacturing it by the user. When the electrical control performance does not meet the engineering design requirements, modifications or redesigns should be requested from the consumer.
