Form preferable sealing effectiveness between the two, make the advantage of antileaking during the closedown of ball valve.
By using the body of said structure, there is simple in construction and the higher advantage of intensity.
In the valve body of above-mentioned a kind of ball valve, the outer rim in the described cross section sealing convex body
At right angles.The cross section sealing convex body is rectangular in shape, and has the preferable advantage of sealing effectiveness.
In the valve body of above-mentioned a kind of ball valve, the lateral wall of described installation portion is provided with convex
The spacing convex body gone out, described spacing convex body is near described water inlet end.By arranging limit
Convex body processed, it is simple to carry out spacing to the rotational angle of valve rod, has simple in construction and spacing
The preferable advantage of effect.
In the valve body of above-mentioned a kind of ball valve, the rectangular in cross-section of described spacing convex body,
And the lateral wall round-corner transition of described spacing convex body.The rectangular in cross-section of spacing convex body and
Fillet is excessive, has and uses safer and be difficult to the advantage scratching operator.
In the valve body of above-mentioned a kind of ball valve, the inner side of described installation portion is provided with screw thread
Hole and bellmouth, described screwed hole is positioned at the upside of described bellmouth.By setting
Put screwed hole and bellmouth, make the assembling conveniently advantage of this valve body.
In the valve body of above-mentioned a kind of ball valve, the inclination angle of described bellmouth is
15°-25°。
Compared with prior art, the valve body of this kind of ball valve has an advantage in that
1, by above-mentioned above-mentioned sealing convex body, when valve seat is resisted against on sealing convex body,
Form preferable sealing effectiveness between the two, make the advantage of antileaking during the closedown of ball valve；
2, the cross section sealing convex body is pointed shape, has the preferable advantage of sealing effectiveness；
3, by arranging restriction convex body, it is simple to the rotational angle of valve rod is carried out spacing, tool
