VENTURI-SHAPED VARIABLE AIR VOLUME CONTROL UNIT

摘要

The present invention relates to a venturi-shaped variable air volume control unit, comprising: a housing, wherein a venturi part is formed on an inner circumferential face; an opening and closing member which consists of a shaft installed on the center inside the housing through a support, and an opening and closing adjustment cone coupled to the shaft to adjust an opening and closing degree of the venturi part; an actuator fixed and coupled to an outer periphery of the housing such that a rotary axis is installed on and connected to the support in a state of penetrating the housing; and an interworking transfer part installed and connected between the shaft and the rotary axis to transfer rotary force of the rotary axis by converting into rectilinear motion. Accordingly, the opening and closing degree of the venturi part is adjustable by the opening and closing adjustment cone by moving the shaft forward and backward in accordance with normal and reverse rotation operation of the actuator.;COPYRIGHT KIPO 2016
