Abstract
The utility model relates to an exhaust steam valve float capable of preventing adhesion to an upper cover. The upper surface of the float is a plane. The utility model is characterized in that the upper surface of the float is provided with support points with the same height, which are higher than the float surface. As for the cylindrical float, the support points are distributed on one circumference. By adopting the structure, the upper surface of the float and the inner surface of the upper cover only form point contact, and a slit is formed between the upper surface of the float and the inner surface of the upper cover, thereby effectively preventing the float from adhering to the inner surface of the upper cover. The structure provided by the utility model is especially suitable for a vertical cylindrical exhaust steam valve.
Description
Technical field
The utility model belongs to the exhaust steam valve parts.
Background technique
Exhaust steam valve especially vertical type cylinder shape exhaust steam valve loam cake inner face is a plane, and ball float supporting with it is cylindrical, and the upper surface of ball float also is the plane; Both area of contact are bigger; Because ducted medium particularly contains a large amount of impurity in the water, these impurity can be piled up on the plane of loam cake and ball float, can cause ball float and loam cake to produce adhesion; And the ball float weight of general vertical exhaust steam valve is lighter; Downward pulling force is little, can't ball float be left behind from covering of adhesion, thereby cause opening of valve malfunctioning.
The model utility content
The purpose of the utility model is to provide a kind of exhaust steam valve ball float of anti loam cake, and shown in accompanying drawing 1, the utility model ball float upper surface is the plane, and it is characterized in that has the highly identical fulcrum that exceeds the ball float surface on the upper surface of ball float.For cylindrical ball float, fulcrum is distributed on the same circumference.After adopting said structure, the ball float upper surface is that point contacts with the loam cake inner face, and a slit is arranged between ball float upper surface and the loam cake inner face, can prevent effectively that ball float and loam cake inner face from producing adhesion.The structure of the utility model is particularly suitable for vertical type cylinder shape exhaust steam valve ball float.
Description of drawings
Accompanying drawing 1 is the utility model assembling design sketch.
Accompanying drawing 2 is ball float plan views that four fulcrums are arranged.
Accompanying drawing 3 is ball float plan views that three fulcrums are arranged.
Accompanying drawing 4 is Fig. 2 plan views.
Accompanying drawing 5 is Fig. 3 plan views.
Legend: 1, fulcrum, 2, ball float.
Embodiment
That the ball float that this instance provides is applicable to is high 80 millimeters, the vertical type cylinder shape exhaust steam valve of 30 millimeters of valve pocket diameters.
Instance one, shown in accompanying drawing 2 and accompanying drawing 5,4 fulcrums that distribute on the circumference of ball float upper surface, fulcrum exceeds 1.5 millimeters of ball float upper surfaces.
Instance two, shown in accompanying drawing 3 and accompanying drawing 5,3 fulcrums that distribute on the circumference of ball float upper surface, fulcrum exceeds 1.2 millimeters of ball float upper surfaces.
Claims (2)
1. the exhaust steam valve ball float of anti loam cake, the ball float upper surface is the plane, it is characterized in that has the highly identical fulcrum that exceeds the ball float surface on the upper surface of ball float.
2. according to the exhaust steam valve ball float of the said anti loam cake of claim 1, it is characterized in that fulcrum is distributed on the same circumference.
