APPARATUS FOR EXHAUSTING GAS

摘要

PURPOSE: An apparatus for exhausting gas is provided to easily and stably exhaust toxic gas existing in a chamber by forming a Venturi tube at an exhaust line. CONSTITUTION: The gas exhaust apparatus comprises a chamber(14), a vacuum line(22) formed between the chamber(14) and a pumping part(18), and an exhaust line(20) formed at other end of the chamber(14). The exhaust line(20) further includes a Venturi tube(10) and a solenoid valve(12). The Venturi tube(10) is inhaled toxic gas remaining in the chamber(14) and transferred the toxic gas. The solenoid valve(12) is injected air to the Venturi tube(10).
