Abstract
The utility model discloses an online calibration device used for a pressure gauge for petroleum drilling operation and relates to the technical field of pressure gauge calibration in petroleum drilling operation. The online calibration device is mainly composed of a pressure pipeline, a to-be-calibrated gauge, a tee joint and a pressure gauge calibrating table. The tee joint includes a first hole end, a second hole end and a third hole end. The first hole end is communicated with the pressure pipeline through a valve I. The second hole end is communicated with a standard pressure source of the pressure gauge calibrating table through a valve II. The third hole end is communicated with the to-be-calibrated gauge directly. A standard pressure gauge is arranged on the pressure gauge calibrating table. The standard pressure gauge is connected with a computer. By using the online calibration device used for the pressure gauge for petroleum drilling operation, pressure gauge regular calibration service can be provided in petroleum drilling operation fields and online calibration of the pressure gauge can also be realized conveniently and quickly. And calibration time is shortened.
