Abstract
The invention discloses a valve pressure resistant sealing ring material, and relates to the technical field of sealing ring manufacturing. The valve pressure resistant sealing ring material is prepared from the following raw materials in parts by weight: basic oil, dimethyl maleate, alkyl polyglucoside, kukui nut oil, sodium formate, carboxymethyl chitosan, poly-polyvinyl pyridine, nano ferroferric oxide microspheres, polyvinyl acetate, silicon dioxide powder, a beeswax matrix, plant extract oil, butyl rubber, modified butyl acrylate, a modified organic silicon phenolic aldehyde epoxy resin, high-pressure low-density PE (Polyethylene), graphene, a polyamide fiber and polytetrafluoroethylene. The valve pressure resistant sealing ring material disclosed by the invention is good in high pressure resistance, high temperature resistance, low temperature resistance and corrosion resistance, not liable to break, long lasting in use and applicable to preparation of sealing rings, and due to adoption of the high-pressure resistance PE and the graphite, the toughness and the tensile strength of the material are improved.
Description
Technical field: [0001] The invention relates to the technical field of sealing ring preparation, in particular to a material of a valve pressure-resistant sealing ring. 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. [0003] 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 s...
