Abstract
The present disclosure relates to a dispensing valve and a pumping machine. The dispensing valve is swingably mounted inside the hopper to transport a fluid material. The dispensing valve includes: a petticoat valve including a feed port, a discharge port, and a pumping chamber formed inside the petticoat valve and communicating the feed port with the discharge port; and a swing shaft arranged on an outer side of the petticoat valve and connected to the petticoat valve, configured to be rotatably connected to the hopper and driving the petticoat valve to swing relative to the hopper under drive of a drive system, wherein in a plane perpendicular to the swing shaft, a projection of the swing shaft does not coincide with projections of the feed port and the discharge port, and a product by multiplying an area of the feed port by a distance from a centroid of the feed port to the swing shaft is equal to a product by multiplying an area of the discharge port by a distance from a centroid of the discharge port to the swing shaft. The embodiments of the present disclosure can reduce the phenomenon of concrete accumulation in the dispensing valve.
