Basic Knowledge of Butterfly Valve
Butterfly valve is a commonly used valve, widely used in water treatment, petrochemical and other fields. Its main structure is a butterfly-shaped valve plate, which controls the flow of fluid by rotating. For many people may not know much about this kind of valve, today we will talk about the common problems of butterfly valve.

1. What is the working principle of the butterfly valve?
The working principle of Butterfly Valve is actually very simple. The gap between the valve plate and the valve seat is cleverly designed so that when the valve stem is rotated, the valve plate opens or closes accordingly, thus regulating the flow of fluid. For fluid control, it is simply handy!

2. For which applications are Butterfly Valves suitable?
When it comes to applications, they are really varied. Butterfly valves are generally suitable for medium and low pressure fluid media, such as water, air and so on. They are especially widely used in water treatment systems and HVAC. However, it is worth noting that if they are used in high temperature and high pressure environments, it is necessary to consider other types of valves.

3. How to choose the right Butterfly Valve?
When choosing butt-pinch butterfly valve, first of all, we should clarify what medium is used, and secondly, we should pay attention to the material, size and pressure level of the valve. Don't forget, quality is also the key, choose the brand, look at the reputation, in order to buy at ease. In the end, choose the right valve, the later maintenance is also less trouble.

4. Maintenance precautions for butterfly valves
Maintenance of butterfly valve is not complicated, but should not be taken lightly. Regularly check the sealing performance of the valve to ensure that there is no leakage; at the same time, clean the valve body to avoid clogging of impurities. Every once in a while, add some lubricant to the valve stem to ensure its flexibility. Hey, if the maintenance work is done well, the valve life is naturally long.

5. Common failures and solutions
Even the best valves, but also inevitably encounter some small problems. For example, the valve can not be opened or closed properly, this may be due to stem damage or aging seals. The solution is to replace these damaged parts in a timely manner, do not let small problems evolve into big trouble!

Summarize
Clamp butterfly valve is more and more widely used, understand its working principle, purchase skills and maintenance methods, for our future use are very beneficial. We hope that through this article, we can help you to better understand the butterfly valve, solve common problems, and do a good job!
