Abstract
The utility model relates to a measuring device for measuring the cross-section uniform static pressure. The device is used for measuring the cross-section uniform static pressure of a pipeline to be measured. A plurality of pressure equalization holes are formed in the sidewall of the pipeline to be measured. The measuring device comprises annular channels and measuring joints. Each annular channel is sleeved onto the outside of the pipeline to be measured (wherein the pipeline are provided with the pressure equalization holes), two ends the annular channel are in sealing connection with the outer wall of the pipeline to be measured, an annular space is formed by the middle portion of the annular channel and the outer wall of the pipeline to be measured, the inner space of the pipeline to be measured and the annular space are communicated through the pressure equalization holes, the measuring joints are arranged on the annular channels, one end of each measuring joint is communicated with the annular space, and the other end of the measuring joint is connected with an external pressure measuring device. Compared with the prior art, the measuring device of the utility model has advantages of simple and compact structure, easy fabrication, wide application range and high measurement accuracy, and is especially suitable for measuring the cross-section uniform static pressure when the distance between pipelines to be measured is small.
Description
Technical field
The utility model relates to measurement mechanism, especially relates to a kind of measurement mechanism for measuring the even static pressure in cross section.
Background technology
The method of measuring at present the even static pressure in cross section is evenly to lay many pipes in the periphery in a cross section, with an end of many pipes and pipeline connection to be measured, and the other end of pipe connected into circulating line, and with laying downhole joint on the circulating line, downhole joint is connected with surveying instrument.The defective of this measuring method is: complex structure, and oversize, in the situation that close together can't be arranged between the measurement inlet manifold pipeline.
