Abstract

The invention discloses a ventilation valve. The ventilation valve comprises a ventilation valve shell, wherein an air return opening, a ventilation opening and a connecting air opening are formed in the side face of the ventilation valve shell, a ventilation door covering the ventilation opening is arranged in the ventilation valve shell, one side of the ventilation door is rotationally connected to the inner wall of the ventilation valve shell, and a driven support is fixed to one face of the ventilation door; and a shaft pin is arranged in the driven support, a driving screw supporting frame is arranged on the wall of the air return opening, a driving screw penetrates through the driving screw supporting frame in a screwed manner, one axial end of the driving screw is rotatably connected with a ventilation door shaft pin guide groove, and the interior of the ventilation door shaft pin guide groove is connected with the shaft pin in the driven support through a kidney-shaped through hole. The ventilation valve is good in leakproofness, long in service life, high in reliability and low in cost, and can be applied to a refrigeration air conditioning system and other air conditioning systems of a closed space or a square cabin.

Description

technical field [0001] The invention relates to the field of dampers, in particular to a fresh air damper. Background technique [0002] With the development of modern refrigeration and air-conditioning and other air-conditioning technologies, as well as the improvement of the comfort requirements of personnel in various confined spaces and shelters, traditional refrigeration and air-conditioning systems and other air-conditioning systems cannot solve the problem because they can only achieve indoor air circulation. Indoor air pollution prevents the comfort of indoor occupants from being improved. Refrigeration and air-conditioning systems with fresh air functions and other air-conditioning systems are more and more widely used. Realizing the fresh air function generally needs to be installed in refrigeration and air-conditioning systems and other air-conditioning systems. A fresh air valve is designed in the return air duct system in the cabin, and the fresh air volume is i...
