Where is the valve seat of the butterfly valve Detailed explanation of the structure of the butterfly valve

The valve seat of the butterfly valve is a key component of the butterfly valve, located inside the valve body, and is used to control and regulate the flow and pressure of the fluid.

I. The structure of the butterfly valve

The butterfly valve is a fluid control device that can be used to control and regulate the flow and pressure of the fluid. The butterfly valve mainly consists of the valve body, valve, valve shaft, valve stem, and valve seat, etc. Among them, the valve seat is one of the key components of the butterfly valve.

II. The position of the butterfly valve's valve seat

The valve seat of the butterfly valve is a hemispherical structure located inside the valve body, used to control and regulate the flow and pressure of the fluid. The part of the valve seat that contacts the valve surface is called the sealing surface, which can be made of different materials, such as rubber, polytetrafluoroethylene, etc., to adapt to different working environments and media.

III. The working principle of the butterfly valve

The working principle of the butterfly valve is to control the flow and pressure of the fluid by rotating the valve. When the valve is in the closed state, the valve seat is in contact with the valve, and the valve stem is connected to the valve, forming a sealed container; when the valve is in the open state, the valve follows the rotation of the valve stem, allowing the fluid to pass through the gap between the valve and the valve seat, achieving the control and regulation of the flow and pressure.

IV. The application range of the butterfly valve

The butterfly valve is suitable for the flow and pressure control of various media, has the advantages of quick opening and closing, convenient operation, simple structure, small size, and light weight, and is widely used in the fields of petroleum, chemical industry, metallurgy, power, etc.
