The invention relates to the field of pneumatic ash conveying, and discloses a flap valve and pneumatic ash conveying device.The flap valve comprises a shell (7), a flap (5) and an air lifting cap (4), the shell (7) is provided with an inlet (3) located at the upper end and an outlet (8) located at the lower end, the flap (5) is arranged in the shell (7) in a turnover mode, and a through hole is formed in the flap (5); and the gas lifting cap (4) is arranged at the through hole so as to be communicated with two sides of the turning plate (5) through fluid. According to the technical scheme, the through hole and the air lifting cap are arranged on the turning plate, so that the pressure on the two sides can be balanced, and the problem that the turning plate cannot be turned over and opened under the gravity action of materials due to unbalanced pressure is solved. 本发明涉及气力输灰领域，公开了一种翻板阀及气力输灰设备，其中，所述翻板阀包括具有位于上端的入口(3)和位于下端的出口(8)的壳体(7)、可翻转地设置在所述壳体(7)中的翻板(5)以及升气帽(4)，所述翻板(5)形成有通孔，所述升气帽(4)设置在所述通孔处以流体连通所述翻板(5)的两侧。通过上述
