Fig. 2 is that the utility model Anti-caking dome valve is opened and without structural representation during material.
Fig. 3 is the structural representation of the utility model Anti-caking dome valve when opening and have material.
Embodiment
Below only with the enforcement aspect that implementation the utility model is possible, but and be not used to limit the utility model institute for protect category, first give chat bright.
As shown in Figure 1-Figure 3, the utility model provides a kind of Anti-caking dome valve, be arranged between two docking conveyance conduits, it is applicable to the conveying of metallurgy, coloured, the industry bulk granular such as chemical industry, electric power, granular material, is transferred the material that material can be the high or easy moisture absorption of water content.As shown in the figure, the utility model Anti-caking dome valve comprises valve body 1 and pneumatic actuating device 2, and these valve body 1 two ends are respectively equipped with material feeding mouth 11 and discharge port 12, and material flows into from material feeding mouth 11 by the direction of arrow in figure, flows out from discharge port 12.This valve body 1 inside be provided with can around the shaft 3 rotate ball tops 4.This rotating shaft 3 is connected with the output terminal of this pneumatic actuating device 2 through this valve body 1 sidewall.This material feeding mouth 11 place is provided with top board 5, is provided with circular hole in the middle part of this top board 5, and this circular hole is provided with the material scraping plate 51 for scraping material on this ball top 4 to downward-extension.Gas-flow closure circle 6 is provided with, when inflating with this ball top 4 close contact and this material feeding mouth 11 closed inside this top board 5.
The concrete fixed structure of gas-flow closure circle 6 of the present utility model is: inside this top board 5, be installed with pressed on ring 7, and this gas-flow closure circle 6 is fastened on the inner side surface of this pressed on ring 7, below this pressed on ring 7, be installed with lower ring 8, and this gas-flow closure circle 6 is supported on this lower ring 8.In addition, this gas-flow closure circle 6 between this material scraping plate 51 and this lower ring 8, make dome valve unlatching and in Flow of Goods and Materials process, material does not contact with this gas-flow closure circle 6, to protect seal ring.
The Anti-caking dome valve that the utility model provides, the ball surface on its ball top 4 is carried out hard plating and is formed solid chromium 41, and do polishing treatment, with the adhesion between the ball surface reducing possible harden material and ball top 4, in addition, gap between material scraping plate 51 and ball top 4 is 0.4mm, or less, so that the ball surface of material from ball top 4 of hardening scrapes by material scraping plate 51.
Gas-flow closure circle 6 of the present utility model inflate time and this ball top 4 close contact, and the gap when exitting and between this ball top 4 is 2.0mm or larger, to avoid a small amount of material that ball top 4 exists to damage gas-flow closure circle 6, the working life of seal ring obtains very large prolongation.
As shown in Figure 1, Anti-caking dome valve is in closed condition, and the high or easy moisture absorption material 9 of water content to contact with ball top 4 at Anti-caking dome valve top and top board 5 and cut off by ball top 4, and gas-flow closure circle 6 is inflated and contacted with ball top 4 and plays seal action.The surface, ball top 4 that high with water content with gas-flow closure circle 6 or easy moisture absorption material 9 contacts is solid chromium 41, polishing mirror process is done on hard plating surface, thus water content is high or the material 9 of the easy moisture absorption not easily hardens on ball top 4, ensure that the mobility of the high or easy moisture absorption material of water content.
As shown in Figure 2, during valve opening, gas-flow closure circle 6 is vented, gap between seal ring and ball top 4 becomes 2.0mm or larger, ball top 4 drives half-twist by pneumatic actuating device 2, Anti-caking dome valve is in opening state, rotate in opening process on ball top 4, material on ball top 4 likely hardens on the sphere on ball top 4, because hard plating process is done on the ball surface on ball top 4, the ball surface adhesion force on material and ball top 4 of hardening is very little, in addition, gap between the material scraping plate 51 of top board 5 and ball top 4 is 0.4mm or less, drive in the process of half-twist on ball top 4 by pneumatic actuating device 2, the material may hardened in ball top 4 is wiped off by material scraping plate 51, gas-flow closure circle 6 is protected, even if there is a small amount of material on ball top 4, because the gap between gas-flow closure circle 6 and ball top 4 is very large, for 2.0mm or larger, also gas-flow closure circle 6 can not be damaged, the working life of seal ring obtains very large prolongation.
As shown in Figure 3, Anti-caking dome valve open after material through valve, gas-flow closure circle 6 is in material 9 both sides and have certain distance from material 9, and material 9 pairs of gas-flow closure circles 6 are without any wearing and tearing.
Find that advantage of the present utility model is as follows by above-mentioned being not difficult:
1, gas-flow closure circle of the present utility model ball top in valve commutation process does not contact with seal ring, gap is large, without wearing and tearing.
The material scraping plate of 2 the utility model top boards is more much smaller than the gap on seal ring and ball top with gap, ball top, and ball top surface hard plating, reduces the adhesion of material and ball top surface, is convenient to the material scraping plate material that will harden and scrapes.
3 gas-flow closure circles of the present utility model in Flow of Goods and Materials process not with material contact wear, substantially prolongs its working life.
The utility model limited with claim.But based on this, those of ordinary skill in the art can make all obvious changes or change, all should within main spirits of the present utility model and protection domain.
