进口软密封三偏心蝶阀characteristic:

Soft sealing tri eccentric butterfly valve, including valve stem, support, valve plate pressing plate and both ends of the valve body with sealing surface, is provided with inlet and outlet, the top of the valve body is provided with a support through bolts, the inside of the valve body is provided with a valve stem, the top of the valve stem runs through the top and support of the valve body and extends out of the support, the middle bottom of the valve body is provided with a lower gland through bolts, the inside of the lower gland is provided with a groove, and the bottom of the valve stem is provided with a valve stem base through screws, The lower part of the center of the valve stem base is provided with a bulge, the bottom of the valve stem penetrates the bottom of the valve body, and the bulge contacts the groove. The valve plate is installed on the surface of the valve stem set in the internal cavity of the valve body through bolts. A sealing ring is installed on the edge of the surface of one side of the valve plate. The upper and lower ends of the pressure plate are provided with screw grooves. The pressure plate is installed on the surface of the valve plate through screws, and the internal side of the valve body is provided with a sealing surface, In addition, the inner side of the sealing surface contacts with the sealing ring, and the sealing ring is fixed by pressing the pressing plate. By setting the sealing ring between the pressing plate and the valve plate, the wear of the sealing ring can be effectively reduced, thus extending the service life of the valve. When the valve plate is closed, the sealing ring contacts the inner side of the sealing surface, which can effectively improve the sealing performance of the valve, and also reduce the wear of multiple sealing rings.

进口软密封三偏心蝶阀Principle:

The working principle is: the pressing plate squeezes the sealing ring to fix the sealing ring. By setting the sealing ring between the pressing plate and the valve plate, the wear of the sealing ring can be effectively reduced, thus extending the service life of the valve. When the valve plate is closed, the sealing ring contacts the inner side of the sealing surface, which can effectively improve the sealing performance of the valve, and also reduce the wear of multiple sealing rings, The position where the lower surface of the valve stem contacts the bottom of the valve body is sleeved with a lower shaft sleeve, which is conducive to reducing the friction between the valve stem surface and the valve body. The inner part of the sealing surface is provided with a rubber pad, which contacts with the sealing ring, which is conducive to improving the sealing effect of the valve. The inner part of the screw groove is sealed with waterproof glue, which is conducive to preventing the screw from contacting with water for a long time and causing the screw corrosion and damage.
