Abstract
An anticorrosion diaphragm valve of cock valve made up of Al-Mg alloy instead of cast iron or stainless steel features that it is made up of Al, Mg, Ti and Ni through proportioning, smelting, degassing, refining, removing slags, regulating temp, casting with sand mould, removing sand and quenching. Its advantage is long service life elongated by 2-16 times compared with the ones made of cast iron or stainless steel.
Description
The present invention relates to a kind of chemical industry equipment accessory, particularly a kind of aluminium matter barrier film valve and plug valve.
Up to the present, traditional chemical industry equipment valve all adopts cast iron or stainless material to make.Corrosion resistant performance of both materials and attrition resistant performance are all poor, thereby influence its work-ing life.Because often scrapping of replacing stopping production that valve caused and old valve makes application units suffer very big financial loss.
The objective of the invention is to provide a kind of to the public and mainly make of aluminum magnesium alloy, corrosion resistance nature and attrition resistant performance are than cylinder iron or the anticorrosion valve of aluminium matter of the strong manyfold of valve made of stainless steel.
Technical scheme of the present invention is:
Realize goal of the invention with the method for changing material, adopt hydronalium, to replace present cast iron or stainless material.The metal of valve partly adopts aluminium ingot, magnesium ingot, and titanium and nickel is by the prescription charging, and its technological process is through dissolving, the degasification refining, skim, temperature adjustment, cast, sand mold casting, knockout and quench treatment etc. are made into diaphragm valve and stopcock.
With diaphragm valve and the stopcock that the aluminum magnesium alloy material is made, be applied in the metalwork of the various structures of subordinate of two kinds of valves: the ridge type of diaphragm valve, cut-off type, flashboard type; The filling-material structure through type of stopcock, filling-material structure T type three way type, filling-material structure four-way formula, oil enveloping structure through type, oil enveloping structure T type three way type.
In diaphragm valve of the present invention and stopcock finished parts metal material, main aluminium (Al) accounts for 60-90%, magnesium (Mg) 3-15%, and surplus is nickel (Ni) 3-15%, titanium (Ti) 3-15%.
This material mainly should be used for casting diaphragm valve and two kinds of valves of stopcock of all size.As Dg15, the Dg25 of Dg50, the Dg65 of diaphragm valve, DG80, Dg100, Dg150 etc. and stopcock, Dg40, Dg50, Dg60, Dg80, Dg100, Dg125, Dg150 or the like.
The invention has the advantages that:
Valve with aluminum alloy material is made as stopcock, diaphragm valve, all has stronger corrosion resistance nature, and greatly prolong its work-ing life.Stopcock of the present invention surpasses stainless 2-4 doubly work-ing life, surpasses 8-16 times of cast iron quality; Diaphragm valve of the present invention surpasses 3-5 times of cast iron quality work-ing life, and diaphragm pad also improves life-span 4-6 doubly.
The invention will be described further below in conjunction with embodiment.
Embodiment 1
Of the present inventionly mainly form by valve gap, valve body and the blocking-up mechanism that can cut off valve flowing channel, hardware in the above-mentioned formation part is all made moulding according to conventional aluminium alloy smelting, casting process, in the metal material of the diaphragm valve of all size and stopcock finished parts, aluminum alloy materials requires to contain aluminium (Al) and accounts for 75%, magnesium (Mg) 8%, surplus is nickel (Ni) 8%, titanium (Ti) 9%.
Ready-made aluminium alloy smelting, the casting process aluminium alloy of this routine is to adopt aluminium ingot, magnesium ingot, titanium (being mixed with aluminium one titanium master alloy) and metallic nickel to be made by cooperating through traditional dissolving → degasification refining → skim, temperature adjustment, cast → sand mold casting → technologies such as knockout → quench treatment.Form the blocking-up mechanism of valve of the present invention, because of valve types difference concrete structure, the specification of sand mold mould, core box is also inequality.
Embodiment 2
Of the present inventionly mainly form by valve gap, valve body and the blocking-up mechanism that can cut off valve flowing channel, hardware in the above-mentioned formation part is all made moulding according to conventional aluminium alloy smelting, casting process, in the metal material of the diaphragm valve of all size and stopcock finished parts, aluminum alloy materials requires to contain aluminium (Al) 90%, magnesium (Mg) 4%, surplus is nickel (Ni) 3%, titanium (Ti) 3%.
Surplus with embodiment 1.
Embodiment 3
Of the present inventionly mainly form by valve gap, valve body and the blocking-up mechanism that can cut off valve flowing channel, hardware in the above-mentioned formation part is all made moulding according to conventional aluminium alloy smelting, casting process, in the metal material of the diaphragm valve of all size and stopcock finished parts, aluminum alloy materials requires to contain aluminium (Al) and accounts for 60%, magnesium (Mg) 14%, surplus is nickel (Ni) 13%, titanium (Ti) 13%.
Surplus with embodiment 1.
