Pressure online detection auxiliary device and detection method thereof

Abstract

The invention relates to a pressure online detection auxiliary device and a detection method thereof, which can solve the problems that pressure instruments and meters on large-scale equipment can not be detached and the detection can not be performed at present. The device comprises a pipeline detection cavity, wherein the outside of the pipeline detection cavity is of the shape of a hexagonal prism, the inside of the pipeline detection cavity is of a hollow cylindrical cavity, a control knob I and a control knob II are respectively mounted on the two bottom surfaces of the external hexagonal prism of the pipeline detection cavity, and a calibration port, a pressure gauge direction interface and a pipeline direction interface are respectively arranged on the three adjacent side surfaces of the external hexagonal prism of the pipeline detection cavity; and when detection is performed, the pressure output end of a pressure checker is connected with the calibration port, the control knobs I and II are adjusted to communicate the calibration port with the pressure gauge direction interface, the direction of the pipeline direction interface is cut off, and a hand pump of the pressure checker is utilized for pressurizing a checked pressure gauge so as to realize full-range verification of the pressure gauge. The device has the advantages of compact structure, convenience in use, simplicity in maintenance, capability of performing online verification without detaching the instrument and great popularization value.

Description

technical field [0001] The invention relates to an auxiliary device for on-line detection of pressure instruments and meters in the machining industry and a detection method thereof, which solves the problem of pressure instruments and meters on large-scale equipment at present. [0002] Impossible to disassemble without detecting the problem. Background technique [0003] In the machining industry, whether it is a high-temperature furnace of imported equipment or a domestic CNC machine tool, there are often some pressure instruments and meters that need to be disassembled, which will cause pressure leakage and continuous operation, resulting in shutdown. If the pressure instruments on the equipment are not detected, it will directly lead to product failure. Failure to do so will result in unimaginable consequences. Contents of the invention [0004] The invention provides an auxiliary device for online pressure detection and a detection method thereof. Using the auxiliar...
