Problems solved by technology

When the wind plate continues to rotate close to the maximum position, due to the effect of inertia, the wind plate will continue to rotate, causing the drive gear to continue to rotate, which is likely to cause gear slippage, especially for large wind plates, the wear of the gear is more serious, and the maintenance cost higher

Abstract

The invention discloses a ventilation valve with a limiting device. The ventilation valve with the limiting device comprises a housing, wherein a wind guide plate cross shaft for mounting a wind guide plate is arranged in the middle of the housing; a driving pivot is arranged in the housing; a separable driving gear is arranged on the driving pivot; a wind guide plate gear is arranged at the tail end of the wind guide plate cross shaft; the wind guide plate gear is matched with the driving gear. In the ventilation valve with the limiting device, with adoption of a locating shoulder on the wind guide plate gear and an adjusting screw on the housing, a user can adjust a relative position between a locating pin on the adjusting screw and the locating shoulder according to the stroke requirement of the wind guide plate; when the wind guide plate reaches the maximal stroke, the ventilation valve can stop automatically to prevent the ventilation valve from continuously rotating to cause slippage of the gear, so that the reliability and the service life of the ventilation valve are greatly improved and prolonged.

Description

technical field [0001] The invention relates to an industrial ventilator, more precisely, a ventilation valve with a limit device. Background technique [0002] The ventilation valve is a common industrial ventilation device, which is usually set on the main air duct to control the air flow on the main air duct. When the wind plate continues to rotate close to the maximum position, due to the effect of inertia, the wind plate will continue to rotate, causing the drive gear to continue to rotate, which is likely to cause gear slippage, especially for large wind plates, the wear of the gear is more serious, and the maintenance cost higher. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a ventilation valve with a limiting device. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A ventilation valve with a limit devic...
