Abstract
The invention discloses a kind of water pipe valves of service life that can be improved valve body, using copper as primary raw material, using iron, aluminium, zinc, magnesium, tin, nickel, barium, chromium, titanium, zirconium, niobium and tungsten as auxiliary material, and inovulant is added and nodulizer melting and casting forms, it is characterized in that, using copper as primary raw material, using iron, aluminium, zinc, magnesium, tin, nickel, barium, chromium, titanium, zirconium, niobium and tungsten as auxiliary material, and inovulant being added and nodulizer melting and casting forms, ingredient and each material mass degree are：Cu25-35%, Fe7-28%, Al97-30%, Zn4-25%, Mg2-6%, Sn3-10%, Ni2-17%, Ba1-8%, Cr0.2-2.7%, Ti0.2-4.3%, Zr1-4.4%, Nb0.1-1.9%, W1.3-0.6%, C0.2-0.9%, Si0.2-1.7%, remaining is impurity.
Description
Technical field
The present invention relates to valve fields, more particularly to a kind of water pipe valve of service life that can be improved valve body.
Background technique
Precision casting is a kind of cast product for exempting from processing or machining allowance very little, and quality requirement is higher.Bearing is machine
Important connecting component component in tool component.Bearing is often formed with casting method at present, still, the bearing essence of prior art
There are following points for close casting method：It is unreasonable to be poured formula of liquid setting, and is bred at nodularization process during hot investment casting
It manages bad, to cause the metallographic and hardness of product, intensity and elongation percentage that requirement is not achieved, is not able to satisfy using needing
It asks.Existing valve water flowing is used for a long time, and valve body is influenced to be easy to happen oxidation reaction by water, and valve body is caused to damage.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of water pipe valve of service life that can be improved valve body,
It can be improved the service life of valve body, manufacturing cost is low, securely and reliably.
In order to solve the above technical problems, one technical scheme adopted by the invention is that：
A kind of water pipe valve for the service life can be improved valve body, which is characterized in that using copper as primary raw material, with iron, aluminium,
As auxiliary material inovulant is added and nodulizer melting and casting forms in zinc, magnesium, tin, nickel, barium, chromium, titanium, zirconium, niobium and tungsten,
Its ingredient and each material mass degree are：Cu25-35%,Fe7-28%,Al97-30%,Zn4-25%,Mg2-6%,
Sn3-10%、Ni2-17%、Ba1-8%、Cr0.2-2.7%、Ti0.2-4.3%、Zr1-4.4%、Nb0.1-1.9%、W1.3-0.6%、
C0.2-0.9%, Si0.2-1.7%, remaining is impurity.
The beneficial effects of the invention are as follows：A kind of water pipe valve for the service life that can be improved valve body of the present invention, can
The service life of valve body is improved, manufacturing cost is low, securely and reliably.
Specific embodiment
The present invention is further described combined with specific embodiments below.
A kind of water pipe valve for the service life can be improved valve body, using copper as primary raw material, with iron, aluminium, zinc, magnesium,
As auxiliary material inovulant is added and nodulizer melting and casting forms, ingredient in tin, nickel, barium, chromium, titanium, zirconium, niobium and tungsten
And each material mass degree is：Cu25-35%,Fe7-28%,Al97-30%,Zn4-25%,Mg2-6%,Sn3-10%,
Ni2-17%、Ba1-8%、Cr0.2-2.7%、Ti0.2-4.3%、Zr1-4.4%、Nb0.1-1.9%、W1.3-0.6%、C0.2-0.9%、
Si0.2-1.7%, remaining is impurity.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
