Abstract
The utility model relates to a ball valve field, and discloses a stainless ball body of a ball valve. The stainless ball body of the ball valve comprises a valve body, a through hole groove is arranged on the valve body, a connecting groove and a rotating groove are arranged on the valve body, stainless steel is welded on the outer ball face and the groove face of the valve body in an overlaying mode, a transitional face is arranged on the connecting portion of the outer ball face of the valve body and the inner wall of the through hole groove, and an included angle b of the transitional face and the outer ball face is between 60 degrees and 80 degrees. Stainless steel layers are welded on the outer surface of a ball body in an overlaying mode to improve overall abrasion resistance and corrosion prevention performance, and meanwhile the complete ball shape structure of the ball body improves the anti-pressure ability of the ball body so that a V-shaped ball valve can be used in a pipeline with high pressure.
Description
Technical field
The utility model belongs to the ball valve field, particularly a kind of stainless spheroid that is welded with stainless ball valve.
Background technique
The present stainless spheroid that the industrial ball valve that abrasion-proof corrosion-proof requires is arranged, if integral material adopts the antifriction metal (AFM) will inevitably too high and its processing trouble of cost, the valve body that has simultaneously adopt the fluoridize technology but also exist wear-resisting rotten layer and spheroid layer in conjunction with insecure unsettled technological deficiency, simultaneously, the stainless spheroid of V-type ball valve in the past is hemisphere, because the restriction of structure can only be applied in the lower pipeline of pressure ratio.
The model utility content
The purpose of this utility model provides a kind of simple in structure, the stainless spheroid of wear-resisting, the corrosion-resistant and ball valve that cost is low.
The purpose of this utility model is achieved through the following technical solutions:
A kind of stainless spheroid of ball valve, comprise valve body, offer a through-hole groove on the described valve body, and offer connecting groove and a swivelling chute of one at valve body, it is characterized in that, described valve body outer spherical surface and the equal built-up welding of groove face have stainless steel weld overlays, and the inwall joint of valve body outer spherical surface and through-hole groove arranges a transitional surface, and the angle b of described transitional surface and outer spherical surface is between the 60-80 degree.
In the stainless spheroid of above-mentioned ball valve, described stainless steel weld overlays thickness is being at least 2mm.
In the stainless spheroid of above-mentioned ball valve, the angle b of described transitional surface and outer spherical surface is being 70 degree.
In the stainless spheroid of above-mentioned ball valve, described stainless steel weld overlays is 316 stainless steel weld overlays.
In the stainless spheroid of above-mentioned ball valve, described connecting groove is reversed convex type.
Compared with prior art, the stainless spheroid of a kind of ball valve of the present utility model, it is by there being stainless steel lining to increase its whole wear resistance and anticorrosive property in the outer surface of spheroid built-up welding, the anti-pressure ability that the full spherical structure of its spheroid of while has improved spheroid also can use the V-type ball valve in the pipeline of high pressure.
Description of drawings:
Fig. 1 is the schematic representation of the stainless spheroid of a kind of ball valve of the utility model.
Fig. 2 is the side view of the stainless spheroid of a kind of ball valve of the utility model.
Mark note among the figure: 100-through-hole groove 200-valve body 300-swivelling chute
The 400-connecting groove
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
With reference to figure 1, Fig. 2: a kind of stainless spheroid of ball valve, comprise valve body 200, offer a through-hole groove 100 on the valve body 200, and offer connecting groove 400 and a swivelling chute 300 of a reversed convex type at valve body 200, wherein, valve body 200 outer spherical surfaces and the equal built-up welding of groove face have thickness to be at least the 316 stainless steel weld overlays (not shown)s of 2mm, the inwall joint of valve body 200 outer spherical surfaces and through-hole groove 100 arranges a transitional surface, the angle b of transitional surface and outer spherical surface is being between the 60-80 degree, and optimum angle b is 70 degree.
The above only is the utility model preferred implementation; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
