TRANSFER APPARATUS OF DYNAMIC PRESSURE FOR SYSTEM OF STANDARD DYNAMIC PRESSURE

摘要

PURPOSE: A dynamic pressure transferring device for a dynamic pressure stand is provided to transfer constant dynamic pressure when instantly opening a needle valve by removing a gap between a pressing unit and a driving shaft, thereby accurately and precisely measuring dynamic pressure. CONSTITUTION: A dynamic pressure transferring device (100) for a dynamic pressure stand includes a needle valve, a pressing unit (120), a driving unit (130), and an impact unit (140). One end portion of the needle valve opens or closes a connection line. The pressing unit is connected to the other end portion of the needle valve, thereby pressing the needle valve to one direction by the rotation. The driving unit connects the needle valve and the pressing unit and includes one or more hinge joining unit, thereby changing the distance between the needle valve and the pressing unit. The impact unit applies impact to the hinge joining unit, thereby rotating the needle valve in one direction by the rotation of the driving unit.
