Easy to understand the basic structure of the butterfly valve

When using butterfly valve products, we also need to understand the basic structure of these butterfly valve products, which will play a guiding role in our use. After all, butterfly valve products are not very complicated, but there are still some high-tech products. If you don't know anything about the product, it is generally difficult to use and maintain it reasonably. The basic structure of the butterfly valve is actually very simple, usually composed of a valve body and valve, plus sealing packing. The valve is the operating body that we mainly use to open and close, which can be said to be the most critical area in the whole butterfly valve product, so the requirements for the valve are generally very high.

　　Valve body is a part other than the valve. We generally call the valve body, in fact, is the entire metal shell. For the valve body, we usually use castings in manufacturing. The material is not as high as that of the valve, and generally does not require special treatment. If it is used under some relatively high pressure, it is usually enough to choose the valve body after comparison. There is another key element in the basic structure of a butterfly valve, naturally the sealing material. Soft materials are often used, but the temperature and corrosiveness of the environment in which they are used must be taken into account. If the problem is too high, high temperature resistant products and corrosion resistant materials should be selected.
