Model No.: cast iron
Flanged soft sealing butterfly valve has novel design structure, small overall size and light weight; the disc adopts double eccentricity, which opens and closes quickly, and the operation is light and labor-saving; there is no sliding friction between the disc and the sealing ring, and the sealing surface is wear-resistant and has a long service life. , The sealing is reliable and easy to adjust.
Vertical plate structure, the valve stem is an integral metal hard sealing valve, the sealing ring is a composite structure of Flexible Graphite Plate and stainless steel plate, installed on the valve body, and the sealing surface of the butterfly plate is surfacing stainless steel. The sealing ring of the soft-sealed valve is made of nitrile rubber/fluorine rubber, etc., and is installed on the butterfly plate. Body and seat surfacing stainless steel.
The design of the metal-sealed valve adopts the principle of triple eccentric structure and utilizes the inherent cam effect, which completely eliminates all friction between the valve seat and the sealing ring during the 90-degree stroke. The design of the rubber soft seal butterfly valve adopts a single eccentric structure, which is different from the centerline soft seal. After the butterfly plate rotates about 20 degrees, the valve seat and the sealing ring are quickly separated, thereby reducing friction.
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.
When the project is used and installed, the flanged butterfly valve is connected between the two pipeline flanges with stud bolts, and the flanges at both ends of the valve are connected to the pipeline flange with bolts.
The wafer butterfly valve has good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, flexibility, safe and reliable use, and has been widely used.
Widely used in cooling water system of petroleum, gas, chemical, water treatment, thermal power station, and SO2, steam, air, gas, ammonia in chemical, petrochemical, smelting, medicine, food and other industries
