FLOW CONTROL DEVICE

摘要

PURPOSE: A flow control device is provided to precisely and uniformly control the flow of fluid by supplying the measured fluid to a position head control container according to a pulse signal of a vibrator. CONSTITUTION: A flow control device is composed of a fluid storing container(100), a measuring container(10) connected to the fluid storing container by a first pipe and temporarily storing measured fluid, a flow restriction unit(16) restricting the fluid of the measuring container, a position head control container(50) connected to the measuring container by a second pipe, a direction control unit(20) coupled with the first pipe and the second pipe, and a control unit electrically connected to a vibrator and controlling the direction control unit according to a pulse signal of the vibrator. The position head control container receives the fluid from the measuring container, and discharges the fluid through a third pipe at regular flow rates. The direction control unit controls the flow direction of the fluid.
