Abstract
The utility model discloses a ball valve comprising a valve body, a valve cover, a valve rod, a wrench and a through hole ball body. The ball valve is characterized in that a through hole opening portion of the through hole ball body is provided with a notch. Compared with a traditional ball valve, the ball valve can control flow, especially micro flow, more easily.
Description
Technical field
The utility model relates to a kind of valve, particularly ball valve.
Background technique
Ball valve is widely used in various industries as a kind of traditional valve, in the various pipelines.Because the special character of ball valve, the ball valve switch stroke is very short.The switching path of clear opening ball valve is generally between the 5-85 degree, even little ball valve switch stroke is the 30-60 degree.So short switching path is so that operator are difficult to control by the flow of ball valve fluid.Moreover because general its through hole of ball valve is circle, the phase cross surface between circle and the circle is larger, and the pressure of adding valve body two side liquids is different, is difficult to control out tiny flow quantity by switch.
Summary of the invention
Problem to be solved in the utility model is: design a kind of ball valve that can control small flow.
For addressing the above problem, the scheme that the utility model adopts is:
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.The via openings place of described through hole spheroid comprises the wedge angle mouth.Consider for symmetry, the via openings place of through hole spheroid both sides can comprise the wedge angle mouth.
Technique effect of the present utility model is:
1, because the wedge angle mouth is little with the surface of contact of circle, thereby more easily controls small flow.
2, the utility model is simple in structure, adds the technique of opening together the wedge angle mouth on existing basis just passable.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.As shown in Figure 1, wherein through hole 2 openings of through hole spheroid 1 comprise wedge angle mouth 3.As shown in Figure 2, the opening of through hole both sides all comprises wedge angle mouth 3, and wedge angle mouth 3 is the breach of through hole 2 openings; Through hole 2 is circular, and is straight.
As shown in Figure 3, ball valve of the present utility model is when switching path is little, see Fig. 3-1, the through hole of its through hole spheroid is compared with the through hole of the through hole spheroid of conventional ball valve and the through hole surface of contact of valve body with the through hole surface of contact of valve body, surface of contact of the present utility model is smaller, thereby has less flow.Along with switching path becomes large, see Fig. 3-2,3-3,3-4, ball valve of the present utility model, when initial, flow increases smaller.Its Contrast on effect is seen Fig. 4.As shown in Figure 4, ball valve of the present utility model flow when initial increases smaller.
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.As shown in Figure 5, wherein through hole 2 openings of through hole spheroid 1 comprise wedge angle mouth 3.
Than embodiment 1, the wedge angle of the present embodiment is young.
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.As shown in Figure 6, wherein through hole 2 openings of through hole spheroid 1 comprise wedge angle mouth 3.Wherein wedge angle mouth 3 has two at the via openings place, is symmetric.
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.As shown in Figure 7, wherein through hole 2 openings of through hole spheroid 1 comprise wedge angle mouth 3.Wherein wedge angle mouth 3 enlarges, and the through hole 2 of integral body is done squarely.
Embodiment 5
A kind of ball valve comprises valve body, valve gap, valve rod, spanner, through hole spheroid.As shown in Figure 8, wherein through hole 2 openings of through hole spheroid 1 comprise wedge angle mouth 3.Wherein wedge angle mouth 3 enlarges, and the through hole 2 of integral body is done diamondwise.
Claims (2)
1. a ball valve comprises valve body, valve gap, valve rod, and spanner, through hole spheroid is characterized in that, the via openings place of described through hole spheroid comprises the wedge angle mouth.
2. ball valve as claimed in claim 1 is characterized in that, the via openings place of described through hole spheroid both sides all comprises the wedge angle mouth.
