Abstract
The utility model relates to a kind of ball valve core.Mainly solve existing stainless steel hollow spherical value spool bearing pressure little, easily deform produce leak problem.It is characterized in that: described spheroid (1) is made up of the Ordinary Steel entity (4) of inside and the stainless steel protecting crust (5) on surface, and stainless steel protecting crust (5) is the airtight outside being wrapped in Ordinary Steel entity (4) evenly.This ball valve core adopts composition metal processing, its inner employing Ordinary Steel, outer surface arranges airtight stainless steel protecting crust, larger pressure can also be carried while meeting wear-resistant, erosion-resisting performance requirement, can not deform, there is the feature of the low and long service life of cost, can meet customer need.
Description
Technical field
The utility model relates to the parts on a kind of valve, is specifically related to a kind of ball valve core.
Background technique
Ball valve is a kind of conventional valve, its open-shut device drives by valve rod the spheroid rotated, spheroid half-twist can control the break-make of pipeline internal medium, be beneficial to and realize Automated condtrol, be mainly used in the fields such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel.Existing ball valve core generally selects single metal material to make, in order to reach wear-resistant, erosion-resisting requirement, in recent years, Stainless Steel Ball valve core is widely applied, and stainless steel material price is higher, particularly for some large-scale ball valves, spool volume is also corresponding very large, full employing stainless steel material processing, processing cost is very high, can not meet customer need.Therefore, there are some hollow spherical value spools, namely stainless steel material is adopted to be processed into the ball valve core of boring, although this stainless steel hollow spherical value spool meets wear-resistant, erosion-resisting performance requirement, also save stainless steel material, reduce processing cost, but its inside is hollow-core construction, the pressure that very difficult carrying is larger, easily deforms and causes poorly sealed, produces and leaks.
Model utility content
In order to overcome existing stainless steel hollow spherical value spool bearing pressure little, easily deform produce leak deficiency, the utility model provides a kind of ball valve core, this ball valve core adopts composition metal processing, its inner employing Ordinary Steel, outer surface arranges airtight stainless steel protecting crust, can also carry larger pressure, can not deform while meeting wear-resistant, erosion-resisting performance requirement, there is the feature of the low and long service life of cost, can meet customer need.
The technical solution of the utility model is: a kind of ball valve core, comprise spheroid, spheroid is provided with through medium through hole, the outer surface of described spheroid is provided with valve rod mounting groove, described spheroid is made up of the Ordinary Steel entity of inside and the stainless steel protecting crust on surface, and stainless steel protecting crust is the airtight outside being wrapped in Ordinary Steel entity evenly.
The thickness of described stainless steel protecting crust is 2 ~ 100mm.
The utility model has following beneficial effect: owing to taking technique scheme, the inside of spheroid is the solid construction of Ordinary Steel entity, there is good non-deformability, can carry larger pressure medium, stainless steel protecting crust can meet wear-resistant, erosion-resisting performance requirement, simultaneously, save the consumption of stainless steel material, reduce cost, long service life, can meet customer need.
Accompanying drawing explanation
Accompanying drawing 1 is structure sectional view of the present utility model.
Accompanying drawing 2 is A-A sectional views of Fig. 1.
1-spheroid in figure, 2-medium through hole, 3-valve rod mounting groove, 4-Ordinary Steel entity, 5-stainless steel protecting crust.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 and Fig. 2, a kind of ball valve core, comprise spheroid 1, spheroid 1 is provided with through medium through hole 2, the outer surface of described spheroid 1 is provided with valve rod mounting groove 3, described spheroid 1 is made up of the Ordinary Steel entity 4 of inside and the stainless steel protecting crust 5 on surface, and stainless steel protecting crust 5 is the airtight outside being wrapped in Ordinary Steel entity 4 evenly.Owing to taking technique scheme, the inside of spheroid 1 is the solid construction of Ordinary Steel entity 4, there is good non-deformability, can carry larger pressure medium, stainless steel protecting crust 5 can meet wear-resistant, erosion-resisting performance requirement, simultaneously, save the consumption of stainless steel material, reduce cost, long service life, can meet customer need.
The thickness of described stainless steel protecting crust 5 is 2 ~ 100mm.The thickness of stainless steel protecting crust 5 is determined according to the diameter of spheroid 1 and the pressure medium of carrying.
Claims (2)
1. a ball valve core, comprise spheroid (1), spheroid (1) is provided with through medium through hole (2), the outer surface of described spheroid (1) is provided with valve rod mounting groove (3), it is characterized in that: described spheroid (1) is made up of the Ordinary Steel entity (4) of inside and the stainless steel protecting crust (5) on surface, and stainless steel protecting crust (5) is the airtight outside being wrapped in Ordinary Steel entity (4) evenly.
2. ball valve core according to claim 1, is characterized in that: the thickness of described stainless steel protecting crust (5) is 2 ~ 100mm.
