[文章前言]:Victor valve is a manufacturer specializing in R & D and production of valves, especially high-temperature valves. Butterfly valves have high temperature resistance, easy to operate, and there is no friction when opening and closing. When closed, the torque of the transmission mechanism increases to compensate for the seal, thereby improving the butterfly valve. dense
Victor valve is a manufacturer specializing in R & D and production of valves, especially high-temperature valves.

Main features of butterfly valve: it is especially suitable for making large-diameter butterfly valve, and the butterfly plate is installed in the direction of pipeline diameter. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0-DEG; And 90 & deg; between. When the rotation reaches 90 DEG; When, the valve is fully open. The utility model has the advantages of simple structure, low cost and large adjustable range. The sealing of butterfly valve is based on rubber, which is far from the metal hard sealing performance of hemispherical valve, ball valve and gate valve. After long-term use of the hemispherical valve, the valve seat will also produce a small amount of wear. You can continue to use it through adjustment. During opening and closing, the valve stem and packing only need to rotate 90 & deg;. When there are signs of leakage, press the packing gland. Several bolts can ensure that there is no leakage of packing, but other valves are still rarely used to deal with small leakage and replace large leakage. The existing relatively advanced butterfly valve is a three eccentric metal hard seal butterfly valve. The valve body and valve seat are connecting parts. The sealing surface layer of the valve seat is welded with high temperature and corrosion-resistant alloy materials. The multi-layer soft laminated sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve has higher temperature resistance, is easy to operate, and has no friction when opening and closing. When closed, the torque of the transmission mechanism increases to compensate for the seal, thereby improving the butterfly valve. Good sealing performance and long service life.
