Document Type and Number:
WIPO Patent Application WO/2021/135811
Kind Code:
A1
Abstract:
Disclosed are a distribution valve and a pumping machine. The distribution valve is mounted inside a hopper (11) in a swingable manner, and is capable of transporting a fluid material. The distribution valve comprises: a skirt valve (2), which comprises a feed port (21), a discharge port (22), and a pumping cavity formed inside the skirt valve (2) and in communication with the feed port (21) and the discharge port (22); and a swing shaft (3), which is arranged on an outer side of the skirt valve (2), is connected to the skirt valve (2), and is configured to be rotatably connected to the hopper (11) and to drive the skirt valve (2) to swing relative to the hopper (11) under the drive of a driving system (31), wherein on a plane perpendicular to the swing shaft (3), a projection of the swing shaft (3) does not coincide with projections of the feed port (21) and the discharge port (22); and the product of an area of the feed port (21) and the distance from the centroid of the feed port (21) to the swing shaft (3) is equal to the product of an area of the discharge port (22) and the distance from the centroid of the discharge port (22) to the swing shaft (3), such that the phenomenon of concrete accumulating in the distribution valve can be reduced.
