Abstract

A ventilation valve, comprising a cylindrical valve body (1), a gear box (2), a plurality of fan-shaped vanes (3) and a drive device (4), the gear box (2) being arranged in the center of the valve body (1), and a geared mechanism being provided inside the gear box (2). The drive device (4), by means of a geared drive mechanism, cause the vanes (3) to rotate in a same direction, each around its own central shaft; the vanes (3) are arranged within the valve body (1) in a uniform distribution; the geared mechanism comprises a first central gear (23) and a second central gear (24) fitted on a same supporting shaft (25); between the first central gear (23) and the second central gear (24) are provided a plurality of gears, one each of which is arranged at the end of one of said central shafts which extends to within the gear box (2), each of said gears engaging with both said first central gear (23) and said second central gear (24). Also arranged within the valve body (1) is one or a plurality of airflow meters (6), the distance between the central axis of each of said one or plurality of airflow meters (6) and the central axis of the valve body (1) is different. The present ventilation valve precisely controls airflow and is safe and reliable, while featuring improved geared mechanism security and reduced wear and tear, thus prolongs the service life of the ventilation valve.
