The Introduction of Products
Electric Flanged Large Caliber Butterfly Valve
Electric Flanged Large Caliber Butterfly ValveButterfly valve disc is installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, disc disc around the axis of rotation, rotation Angle between 0°-90°, rotation to 90°, the valve is in full open state.
Butterfly valve simple structure, small size, light weight, only by a few parts. And only need to rotate 90° can quickly open and close, simple operation, while the valve has good fluid control characteristics. When butterfly valve is in full open position, butterfly plate thickness is the only resistance when medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has good flow control characteristics. Butterfly valve has two sealing types: spring seal and metal seal. Elastic seal valve, sealing ring can be mounted on the valve body or attached to the disc periphery. The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to achieve complete seal. Metal seal can adapt to higher working temperature, elastic seal is limited by temperature defects. If butterfly valves are required to be used as flow control, it is important to correctly choose the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power stations. Commonly used butterfly valves have wafer butterfly valve and flange butterfly valve two. Wafer butterfly valve is connected between two pipe flanges with double-head bolts, flanged butterfly valve is a valve with flanges, with bolts on both ends of the valve flanges are connected to the pipe flanges.
