Abstract
A kind of production technology of ball valve, comprises the following steps：Cast out the matrix of ball valve core first and the matrix of valve body first；The matrix of valve element first is made using intensity metal high and ensure that overall intensity with the matrix of valve body first.The matrix of valve element first in step 1 and the matrix of valve body first are inserted into press-in metal in mould to be cast, the matrix of valve element second and the matrix of valve body second is formed；The corrosion resistance of valve body and valve element is ensure that by the way of the secondary die casting of good corrosion resistance.Lifting is carried out in the molten metal that the matrix of valve element second and the matrix of valve body second are inserted melting be made the matrix of valve element the 3rd and the matrix of valve body the 3rd；The outer surface of matrix of valve element the 3rd is processed by shot blasting, the base inner surface of valve body the 3rd is processed by shot blasting；By by the matrix of valve element the 3rd of polishing with carry out cooperation grinding by the valve body the 3rd of polishing.This invention ensures that corrosion resistance, bulk strength, the surface compact degree of valve body and valve element.
Description
Technical field
The present invention relates to a kind of production technology of ball valve.
Background technology
Ball valve is very high to metal surface corrosion resistance, bulk strength, the requirement of surface compact degree, and corrosion resistance, bulk strength, surface compact degree can be simultaneously ensured there is presently no a kind of metal for being capable of volume production.
The content of the invention
In order to overcome the metal there is presently no a kind of guarantee corrosion resistance for being capable of volume production, bulk strength, surface compact degree not enough, the present invention provides a kind of production technology of ball valve.
The present invention solve its technical problem technical scheme be：A kind of production technology of ball valve, comprises the following steps：
1st, the matrix of ball valve core first and the matrix of valve body first are cast out；The matrix of valve element first is made using intensity metal high and ensure that overall intensity with the matrix of valve body first
2nd, the matrix of valve element first in step 1 and the matrix of valve body first are inserted into press-in metal in mould to be cast, forms the matrix of valve element second and the matrix of valve body second；The corrosion resistance of valve body and valve element is ensure that by the way of the secondary die casting of good corrosion resistance.
Lifting is carried out in the molten metal that the 3rd, the matrix of valve element second in step 2 and the matrix of valve body second are inserted melting be made the matrix of valve element the 3rd and the matrix of valve body the 3rd；Carry out lifting the surface compact degree that ensure that valve body and valve element using the metal of good compactness.
4th, the outer surface of matrix of valve element the 3rd in step 3 is processed by shot blasting, the base inner surface of valve body the 3rd is processed by shot blasting；
5th, by step 4 by polishing the matrix of valve element the 3rd with carry out cooperation grinding by the valve body the 3rd of polishing.
The beneficial effects of the present invention are：Ensure that corrosion resistance, bulk strength, the surface compact degree of valve body and valve element.
Specific embodiment
A kind of production technology of ball valve, comprises the following steps：
1st, the matrix of ball valve core first and the matrix of valve body first are cast out；The matrix of valve element first is made using intensity metal high and ensure that overall intensity with the matrix of valve body first
2nd, the matrix of valve element first in step 1 and the matrix of valve body first are inserted into press-in metal in mould to be cast, forms the matrix of valve element second and the matrix of valve body second；The corrosion resistance of valve body and valve element is ensure that by the way of the secondary die casting of good corrosion resistance.
Lifting is carried out in the molten metal that the 3rd, the matrix of valve element second in step 2 and the matrix of valve body second are inserted melting be made the matrix of valve element the 3rd and the matrix of valve body the 3rd；Carry out lifting the surface compact degree that ensure that valve body and valve element using the metal of good compactness.
4th, the outer surface of matrix of valve element the 3rd in step 3 is processed by shot blasting, the base inner surface of valve body the 3rd is processed by shot blasting；
5th, by step 4 by polishing the matrix of valve element the 3rd with carry out cooperation grinding by the valve body the 3rd of polishing.
