The invention discloses a sanding valve and a sanding device. The sanding valve comprises a sand inlet pipe (1), a sand outlet pipe (2) and an elbow pipe (3), wherein an inflation chamber (6) is arranged on the outer surface of the upper side of the elbow pipe (3), a first baffle (4) used for partially blocking sand flow is arranged on the inner surface of the upper side of the elbow pipe (3), a second baffle (5) used for partially blocking the sand flow is arranged on the inner surface of the lower side of the elbow pipe (3), a sand accumulation part is formed by the second baffle and the lower side portion, located in the upstream position of the second baffle (5), of the elbow pipe (3) jointly, and a first air outlet (61) of the inflation chamber (6) is communicated with the interior of the sanding valve and faces the sand accumulation part. Through the combined action of the two baffles arranged in the sanding valve, sand can be blocked, and leakage can be prevented when the sanding valve is in an off-working state; sand in the sanding valve is raised through the inflation chamber, and thus uniform sanding can be achieved.
