摘要： A valve housing has butt pipes for connection to a pipeline for defining therewith a passage for a flow of a fluid being conveyed, preferably of a slurry. A plurality of ribs are provided along the passage on the lower portion of the wall thereof, each rib extending transversely of the passage. Each rib is of a tear-shaped configuration in its section taken along the longitudinal centerline of the passage, the enlarged portion of the rib facing toward the incoming flow of a fluid being conveyed.
