Static pressure measuring device special for flue

Abstract

The utility model discloses a special static pressure measuring device for a flue, which comprises a measuring assembly, a lampblack pipeline, a connecting sleeve, a first connecting pipe, a static pressure box, a second connecting pipe, a pressure testing instrument, oil absorption filter paper and a cover plate, the connecting sleeve is positioned on one side of the lampblack pipeline, the first connecting pipe is sleeved outside the connecting sleeve, and the static pressure box is sleeved outside the second connecting pipe. The static pressure box is fixed on one side of the oil smoke pipeline, the second connecting pipe is inserted into the static pressure box, and the pressure testing instrument is arranged on one side of the oil smoke pipeline. The static pressure monitoring device has the advantages that the large-diameter first connecting pipe is adopted, the phenomenon that a static pressure test is affected due to the fact that the pressure sampling holes are blocked can be avoided, oil smoke pollutants entering a static pressure monitoring instrument can be reduced to the maximum extent through the buffering effect of the static pressure box, and the service cycle of a static pressure monitoring control system can be prolonged; and only the first connecting pipe and the oil absorption filter paper in the static pressure box need to be replaced, materials are cheap, replacement is convenient, and the maintenance cost is low.
