Abstract
The utility model discloses a ball valve sphere which comprises a valve body. A through hole groove is arranged on the valve body. The ball valve sphere is characterized in that the sphere is an integral sphere, two key grooves are respectively arranged on two sides of the valve body, and the outer spherical surface of the valve body and the groove surface are covered with Ni-P coatings. A joint of the outer spherical surface of the valve body and the inner wall of the through hole groove is a transitional surface. The included angle b between the transitional surface and the outer spherical surface is more than 90 degrees. The Ni-P coating is covered on the outer surface of the ball body to increase the abrasive resistance of the whole, meanwhile the compression resistance of the sphere is improved due to the integral sphere structure of the ball body so that the V-shaped ball valve can be used in a pipe with high compression.
Description
Technical field
The utility model belongs to the ball valve field, and particularly a kind of spheroid is the ball for ball valve of complete spheroid.
Background technique
The present industrial ball for ball valve that has abrasion-proof corrosion-proof to require, 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, V-type ball for 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 ball for ball valve wear-resisting, that cost is low.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ball for ball valve, comprise valve body, offer a through-hole groove on the described valve body, it is characterized in that, described spheroid is a complete spheroid, and respectively has a keyway in the valve body both sides, and described valve body outer spherical surface and groove face all are coated with nickel phosphorus layer, 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 greater than 90 degree.
In above-mentioned ball for ball valve, also be coated with nickel phosphorus layer on the described transitional surface.
In above-mentioned ball for ball valve, described nickel phosphorus layer thickness is between 0.025-0.03mm.
In above-mentioned ball for ball valve, described keyway is a curve bath.
Compared with prior art, a kind of ball for ball valve of the present utility model, it has increased its whole wear resistance by cover nickel phosphorus layer at outer surface of spheroid, and 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 a kind of ball for ball valve of the utility model.
Fig. 2 is the side view of a kind of ball for ball valve of the utility model.
Mark note among the figure: 100-through-hole groove 200-curve bath 300-valve body
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 ball for ball valve, comprise valve body, offer a through-hole groove 100 on the valve body 300, wherein, valve body 300 is a complete spheroid, and respectively have the keyway of a curve bath 200 samples in valve body 300 both sides, valve body 300 outer spherical surfaces and groove face all are coated with thickness nickel phosphorus layer (not shown) between 0.025-0.03mm, the inwall joint of valve body outer spherical surface and through-hole groove 100 arranges a transitional surface, in order to strengthen its wear resistance, its transitional surface also is coated with nickel phosphorus layer, transition layer the above transitional surface and the angle b of outer spherical surface greater than 90 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.
Claims (4)
