Abstract

The invention discloses a chlorine-resistant modified graphite sealing material for valves. The chlorine-resistant modified graphite sealing material for the valves comprises, by weight, 50-60% of tetrafluorohydrazine, 30-40% of graphite, 1-2% of chromium powder, 1-2% of molybdenum powder, 0.5-1.5% of aluminum powder, 0.5-1.5% of tantalum powder, 0.5-1.5% of nickel powder and 2.5-3.5% of copper powder. The chlorine-resistant modified graphite sealing material for the valves has the advantages that made of the graphite and the tetrafluorohydrazine, the valves are effectively improved in chlorine resistance, excellent in sealing performance, higher in strength, long in service life and have less maintenance cost.

Description

technical field [0001] The invention relates to the technical field of sealing materials, in particular to a chlorine-resistant modified graphite sealing material for valves. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel ...
