wafer type butterfly valve is widely used in industrial pipelines such as petroleum, chemical, electric power, steel and metallurgy for cutting or regulating medium flow. The valve is easy to install. The valve is sealed by a three-dimensional eccentric oblique cone seat. The butterfly plate is made of a new metal sheet and an elastic material. It is embedded in the butterfly plate and matched with the valve seat.
The butterfly plate is pressed and pressed tightly, so the frictional resistance of the sealing surface is small, and the function of closing the tighter when closing is closed, so that the sealing property is reliable, and the opening ensures that the sealing surface is completely out of contact, thereby ensuring that the sealing surface is not damaged.
The structure of the api wafer type butterfly valve eliminates the shortcomings of other types of butterfly valves that can not be sealed. The butterfly plate seal adopts new metal sheets and elastic materials, and can be used normally under high temperature, overcoming other types of valves. The disadvantage of easy leakage due to thermal expansion when used at high temperatures. The butterfly valve uses different sealing surface materials according to the requirements of the medium to ensure that the sealing surface is resistant to abrasion, corrosion and long service life.
