Metal seal globe
Manual Gas Valves assembly as one of the fluid medium transport and cut in petroleum, chemical, metallurgy, and urban construction has been widely used. Through the use of different materials, metal sealed globe Manual Gas Valvess can be applied to water, steam, oil, nitric acid, urea and coal ash and other media, so the development of new products to ensure product quality and service life is very important.
Sealing surface with a Manual Gas Valves "heart," said one of the most important face in Manual Gas Valvess, Manual Gas Valves opening and closing work undertaken, the sealing surface will have a direct impact on the life of the Manual Gas Valves, globe Manual Gas Valves seal for sealing hard deputy principal the Manual Gas Valves and seat structure, in order to ensure a better sealing surface wear and corrosion resistance, often in the seat and the Manual Gas Valves on the base alloy or corrosion resistant alloy welding electrode. This paper mainly discussed in the base material for welding technology and improvements on ZG1Cr13 the Manual Gas Valves surfacing of cobalt-based alloy.
