进口高压球阀美国阿卡迪亚品牌

进口高压球阀Product Description: The sealing packing of the pressure ball valve comprises two metal wire pressing rings arranged up and down, and a graphite layer is arranged between the two metal wire pressing rings; The ratio of the thickness of each wire pressing ring to the thickness of graphite layer is 1:1.5 ~ 1:2; The clearance of each wire pressing ring is 300 ? 500 mesh. The sealing packing of high-pressure ball valve is composed of metal wire pressing ring and middle graphite layer. The gap of metal wire pressing ring is very small, which can prevent small particle impurities from entering the packing. At the same time, due to the gap, it has certain elasticity. 进口高压球阀After being pressed, it can closely fit with the valve stem, so as to avoid the problem of medium leakage at the valve stem and improve the safety of high-pressure ball valve. The service life and safety of high-pressure ball valve are high. characteristic: The sealing packing of high-pressure ball valve is composed of metal wire pressing ring and middle graphite layer. The gap of metal wire pressing ring is very small, which can prevent small particle impurities from entering the packing. At the same time, it has certain elasticity because of the gap.进口高压球阀 After being pressed, it can closely fit with the valve stem, so as to avoid the problem of medium leakage at the valve stem and improve the safety of high-pressure ball valve. Principle: The wire pressing ring can effectively prevent the graphite layer in the middle from being extruded due to extrusion pressure. Because a small part of graphite is embedded into the gap of the wire pressing ring after the graphite layer is extruded, the wire pressing ring has a certain sealing effect. The metal wire pressing ring greatly reduces the direct impact of medium pressure P on the packing, protects the packing and improves the service life of the packing.
