Abstract
The invention discloses an air check valve and a slurry spraying machine using the same. The air check valve and the slurry spraying machine using the same mainly solve the problem that according to an existing slurry spraying machine, when slurry enters the slurry spraying machine from a hopper, a feed inlet is communicated with a discharge outlet, so that resistance is formed on a taper pipe at the front end of a screw cylinder due to the fact that materials are squeezed and a high-pressure feeding rubber pipe is too long, and accordingly high-pressure air flows back into the hopper to cause backward spraying of the slurry. The air check valve is characterized in that a shaft core which is driven by a power source to rotate is arranged in a valve body; material conveying plates which rotate along with the shaft core and are used for conveying materials to a discharge outlet from a feed inlet are arranged in the circumferential direction of the shaft core, the number of the material conveying plates is at least three, and the material conveying plates separate the feed inlet from the discharge outlet all the time when the material conveying plates rotate; the end of each material conveying plate is in sealing fit with the inner wall of the valve body. According to the air check valve and the slurry spraying machine using the same, the at least three material conveying plates which are arranged in the valve body and rotate along with the shaft core separate the feed inlet from the discharge outlet all the time during feeding and rotating, and thus airflow is prevented from flowing backwards; the structure is simple, and the use effect is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described: as shown in the figure, a kind of air back valve, comprise valve body 1, described valve body 1 is provided with charging aperture 11 and discharging opening 12, be provided with in described valve body 1 and drive by power source the axle core 2 rotated, described axle core 2 is circumferentially with the conveying plate 21 for material to be sent to discharging opening 12 from described charging aperture 11 rotated with described axle core 2, described conveying plate 21 is provided with at least three and described charging aperture 11 and discharging opening 12 separate when rotating by all the time, and the end of described conveying plate 21 coordinates with described valve body 1 inner wall sealing.Conveying plate is when rotating with axle core, random time node, charging aperture and discharging opening can separate by any one piece or polylith in three blocks of conveying plates, the invention provides a kind of air back valve, at least three the conveying plates rotated with axle core in its valve body, when charging is rotated, all the time charging aperture and discharging opening are separated, prevent reverse flowing of air flows, structure is simple, result of use is good, and can have the effect controlling mass flow.
In the present invention, as shown in Figure 2,3, 4, described axle core 2 outer wall is located in described conveying plate 21 one end, and the other end coordinates with described valve body 1 inner wall sealing; Adjacent described conveying plate 21 forms the hopper 3 being enough to block described charging aperture 11 or discharging opening 12 between any two.Time visible axle core rotates, the Breadth Maximum of the hopper that two adjacent conveying plates are formed is greater than the Breadth Maximum of charging aperture or discharging opening, and when rotation, charging aperture and discharging opening at least one blocked by hopper, so just achieve and charging aperture and discharging opening are separated, conveying plate one end is herein connected with spool in addition, the other end and valve interior wall are sealed and matched, also at least 3 conveying plates can be designed to axle core for the end to end structure in axle center, the former is preferred version, the space of hopper is comparatively large, and result of use is better.
