| 摘要 |
<p>Disclosed is a gas leakage detection apparatus which is installed to be connected to a middle valve body of a main pipe through which gas flows for detecting gas leakage, and comprises an inflow pipe connected to an inflow end of the middle valve body and having an inflow valve for controlling gas inflow from the main pipe, a detection pipe, which is reversely U-shaped and connected to the inflow pipe, an outflow pipe connected between the detection pipe and an outflow end of the middle valve body for controlling gas outflow to the main pipe, and a detection agent filled in the detection pipe and moved back and forth in the detection pipe by a difference between gas pressures of the inflow pipe and the outflow pipe. The gas leakage detection apparatus according to the present invention can sensitively detect even a small amount of leaked gas, thereby preventing gas accidents.</p> |
