SIGHT GLASS FOR FUEL OIL TANK OVERFLOW PIPE AND FUEL OIL TANK OVERFLOW PIPE DEVICE HAVING THE SAME

摘要

Overflow pipe relative to fuel oil tank unit is disclosed including checking the overflow pipe for fuel oil tank and this window. According to the one side of subject innovation, it is arranged to observe the flowing of oil plant stream by inner hollow body part, its overflow pipe for being connected to fuel oil tank, when the observation of oil plant stream, a pair of of peep-hole glass, it is facing with each other for tending to, the inspection of a pair of of glass, and can provide for checking to include multiple light emitting diodes to provide a windowpane of the overflow pipe of the fuel oil tank of illumination. According to the another aspect of subject innovation, it is arranged to observe the flowing of oil plant stream by inner hollow body part, its overflow pipe for being connected to fuel oil tank, and for tending to a pair of of peep-hole glass facing with each other, there is provided to test it in glass and be the pipeline of fuel oil tank, one side overflow check window can be provided containing a flow sensing lighting device, illumination is necessary to the flowing for the oil observed to provide with multiple light emitting diode perceptron oil streams.
