Abstract
The utility model provides a diameter shrinking ash-discharging ball valve comprising a valve body, a valve cover and a ball body, the valve body and the valve cover are permanently connected through bolts, the channel diameter of the valve cover gradually shrinks from the outer side to the inner side, and the channel diameter of the ball body is equal to the minimum channel diameter of the valve cover. The ball valve has the advantages that the ball body size is reduced, the cost is saved, the inner cavity space of the ball valve is increased, the ash-discharging process is smooth, and the service life is longer.
Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of Unloading ball valve.
Background technique
The metallurgy industry blast furnace is controlled dust-containing airflow, is contained in the Unloading ball valve of media such as particle-liquid and pressed powder at present, the channel diameter of general spheroid equals the valve gap channel diameter, the gap is less between spheroid and the valve body, is unfavorable for unloading ash, easily causes dust or solid powder particle blocking channel.
Summary of the invention
Easily stop up, unload the deficiency that ash has some setbacks in order to overcome existing Unloading ball valve, the utility model provides a kind of undergauge Unloading ball valve.
The technological scheme that its technical problem that solves the utility model adopts is a kind of undergauge Unloading ball valve, comprises valve body, valve gap, spheroid, valve body and valve gap are bolted to connection, and the valve gap channel diameter dwindles from outside to inside successively, and the channel diameter of spheroid equates with the minimum diameter of valve gap passage.
The beneficial effects of the utility model are to reduce sphere size, have saved cost, have increased the ball valve intracavity space, and it is smooth and easy to unload grey process, longer service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment
Among the figure: 1. valve body; 2. valve gap; 3. spheroid; 4. valve gap passage; 5. spheroid passage.
Embodiment
As shown in Figure 1, a kind of undergauge Unloading ball valve comprises valve body 1, valve gap 2, and spheroid 3, valve body 1 is bolted to connection with valve 2 lids, and the diameter of valve gap passage 4 dwindles from outside to inside successively, and the diameter of spheroid passage 5 equates with the minimum diameter of valve gap passage 4.
Claims (1)
1, a kind of undergauge Unloading ball valve comprises valve body, valve gap, spheroid, valve body and valve gap are bolted to connection, and it is characterized in that: dwindle successively from outside to inside at described valve gap channel diameter, the channel diameter of described spheroid equates with the minimum diameter of valve gap passage.
