进口软密封双偏心蝶阀美国阿卡迪亚品牌

进口软密封双偏心蝶阀Product Description:

In particular to the technical field of eccentric butterfly valves. It includes the valve body. The inner cavity of the valve body is installed with a valve seat sealing ring. The sealing pressure plate is fixed on the valve body. The valve shaft is installed in the valve body. The valve shaft penetrates the valve body up and down. The lower shaft sleeve is installed below the valve shaft. The upper shaft sleeve is installed above the upper shaft sleeve. The packing gland is installed above the packing. It overcomes the problem that the sealing member of the double eccentric soft sealing butterfly valve in the prior art has a short service life due to medium impact, and the sealing property of the valve is easily damaged if the sealing member cannot be replaced in time. The valve seat sealing ring is installed in the inner cavity of the butterfly valve, and the sealing pressure plate cover is fixed on the valve body with the valve seat sealing ring by using the cylindrical head screw and the set screw to achieve the sealing effect. At the same time, it has a good cutting function and can realize the purpose of real-time replacement of seals.

进口软密封双偏心蝶阀characteristic:

Butterfly valve is a valve with simple structure, which can be used as a cut-off valve or a regulating valve. The existing double eccentric soft seal butterfly valve seal is installed on the valve plate, which is seriously impacted by the medium, has a short service life, a large driving torque of the valve, poor regulating performance, and a small reverse pressure bearing capacity. Therefore, we propose a soft seal double eccentric butterfly valve with on-line replaceable seal to solve the above problems.

进口软密封双偏心蝶阀Principle: the sealing pressure plate is fixed on the valve body by the first Hexagon socket head cap screw and the first Hexagon socket set screw. The valve body is equipped with a valve plate, a valve shaft is installed in the valve plate, a first cylindrical pin is installed between the valve plate and the valve shaft, and the mating surface of the first cylindrical pin and the valve plate is equipped with a second hexagon socket set screw to prevent the first cylindrical pin from falling off. The valve shaft penetrates the valve body from top to bottom, and a lower shaft sleeve is installed under the valve shaft, One side of the lower shaft sleeve is fitted with the valve body, the lower part of the lower shaft sleeve is provided with a split ring, and the lower part of the split ring is provided with a bottom end cap matched with the valve body;
