Description
Technical field
The utility model relates to a kind of valve part, refers to a kind of ball for ball valve especially.
Background technique
Ball valve is a kind of open-shut device of sphere-like, is driven and the valve rotated around the axis of valve rod by valve rod.Existing ball for ball valve is generally cast iron, carbon steel or stainless steel spheroid.Due to the actual conditions bad environments of pipeline performance, the liquid carried, gas or powder are mostly containing acid, the contour corrosive impurity of sulphide and foreign matter, after a period of time, valve ball can be corroded and wear and tear, and causes sealing property of ball valves and Security to decline, must change.
Model utility content
The utility model proposes a kind of ball for ball valve, solve the problem such as corrosion and abrasiveness in prior art.
The technical solution of the utility model is achieved in that
A kind of ball for ball valve, comprises spheroid, through the passage in this spheroid and the groove being located at this spheroid top, described spheroid is silicon nitride ceramics spheroid, and described groove is recessed on spheroid, is provided with the link of one and obturator one in this groove.
Preferred version is, the cross section of described groove is circular.
Preferred version is, described groove comprises the bottom surface of the level of a circle and the periphery upwards vertically extending side by bottom surface, and the bottom surface of this groove and the bottom of side are located on obturator, and the top of the side of this groove is located on spheroid.
Preferred version is, the outer circumferential face of this ball for ball valve is also provided with nickel phosphorous layer, and described nickel phosphorous layer is covered in the whole outer surface of spheroid and groove.
Preferred version is, the thickness of described nickel phosphorous layer is 0.02-0.03mm.
The beneficial effects of the utility model are:
Ball for ball valve in the utility model is silicon nitride spheroid, there is the characteristics such as wear-resisting, corrosion-resistant, high temperature resistant and insulation, the metallic material that alternative traditional valve ball uses and alloy material, overcome the defect of existing valve ball, ensure that the Security of long-term, continuous, the large discharge fed sheet of a media of ball valve, also efficiently solve the large-sized requirement of industrial chemicals conveying environment simultaneously, and extend the working life of ball valve, extend maintenance and the manufacture cycle of pipeline ball-valve, cut operating costs, product cost is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of the utility model ball for ball valve;
Fig. 2 is the sectional view of Fig. 1.
In figure:
100, ball for ball valve; 10, spheroid; 30, passage; 11, groove; 110, bottom surface; 112, side; 13, link.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, this ball for ball valve 100 comprises spheroid 10 and through the passage 30 in this spheroid 10.
Please refer to Fig. 2, described spheroid 10 is silicon nitride ceramics spheroid, is provided with a passage 30 in it.The maximum diameter of this spheroid is 160mm.The top of this spheroid 10 is provided with a groove 11.The cross section of described groove 11 is circular, and it comprises the bottom surface 110 of the level of a circle and the periphery upwards vertically extending side 112 by bottom surface 110.This groove 11 is recessed down by spheroid 10.A connection piece 13 is also provided with in this groove 11, this link 13 is integrally formed with spheroid 10, the warping force that this link 13 can make dwang pass over when ball for ball valve 100 uses is distributed to integrated ball valve spheroid 100 by groove 11 to surrounding extension, the larger warping force of dwang can be born while ball for ball valve 100 is rotated, thus ensure the quality of ball for ball valve 100.
The outer circumferential face of this ball for ball valve 100 also can be provided with nickel phosphorous layer (not shown), and described nickel phosphorous layer is covered in the whole outer surface of spheroid 10 and groove 11, and the thickness of this nickel phosphorous layer is 0.02-0.03mm.
Ball for ball valve 100 of the present utility model is silicon nitride spheroid, there is the characteristics such as wear-resisting, corrosion-resistant, high temperature resistant and insulation, the metallic material that alternative traditional valve ball uses and alloy material, overcome the defect of existing valve ball, ensure that the Security of long-term, continuous, the large discharge fed sheet of a media of ball valve, also efficiently solve the large-sized requirement of industrial chemicals conveying environment simultaneously, and extend the working life of ball valve, extend maintenance and the manufacture cycle of pipeline ball-valve, cut operating costs, product cost is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
