Description
Technical field
The invention belongs to plumbing relevant device fields, and in particular to a kind of plumbing equipment valve member preparation work
Skill.
Background technique
In recent years, petroleum, chemical industry deep process technology have developed rapidly, and corrode to high temperature resistant, wear-resisting, resistant to hydrogen, hydrofluoric acid resistant is rotten
The demand of the valves such as erosion further increases, and is widely used in the industries such as chemical industry, light industry, electric power, safety and warp to system
Ji operation plays particularly important effect.
Valve is control unit in pipeline fluid conveying system, it be for changing access section and flow direction of medium,
Have the function of water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release etc..From simplest shut-off valve to extremely complex automatic control
Various valves used in system, kind and specification are quite various.Valve can be used for controlling empty gas and water, steam, various corrosion
The flowing of the various types fluids such as property medium, mud, oil product, liquid metal and radiating medium.Valve can be divided into according to material
Cast iron valve, cast steel valve, stainless valve, chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve etc..
Copper alloy valve is one of valve, and since it is strong with corrosion resistance, copper alloy is in valve and valve
With abundant application has been obtained on part, crucial effect is played in many fields, but copper valve has some defects, such as:
Rub resistance ability is low, and intensity is low, causes the service life of valve shorter.
Existing valve member material simultaneously, construction material performance is general, and generally existing raw material ratio is complicated, using strong
The problems such as degree is general, and anticorrosion effect is undesirable, and resistance to compression is poor, and processing cost is high, does not meet actual production requirement.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of plumbing equipment use
Valve member preparation process.
Technical solution: in order to solve the above-mentioned technical problem, a kind of plumbing equipment valve member system of the present invention

1.5~4.2 parts of manganese, 0.6~1.7 part of titanium be uniformly mixed；
(2) above-mentioned raw materials are mixed in investment smelting furnace, is heated to 1180-1350 DEG C, melting continues 70~110 minutes, cooling
To 890~960 DEG C；
(3) 4~8 parts of graphene, 5~12 parts of nano-carbon powder are added in smelting furnace after cooling, is heated to 1560~1750
DEG C, heating and continuous 155~220 minutes；
(4) material in step (3) is sent into shaping grinding apparatus, the valve of different size, natural cooling is made；
(5) invention after cooling is subjected to acid washing phosphorization processing, stored dry is completed in processing.
Further, the acid washing phosphorization processing in the step (5) carries out in special closed acid washing phosphorization equipment.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: the present invention by rigorous procedure of processing,
Have excellent performance finished-product material, preparation process is simple, stable components, at low cost, and the present invention be added on raw material it is a variety of
