It by school flange pressure watch case, then reads by the indicating value of school flange pressure table and is recorded, tapping front and back is by school flange pressure
The difference of table and master gauge indicating value had both been the error of indication of the calibrating point, so successively examine and determine directly in the calibrating point of selection
To the measurement upper limit, cut-out pressure source after pressure-resistant 3min, then successively carries out decompression calibrating until zero-bit point by point, record calibrating data,
Verification finishes.The utility model workmanship is simple, cheap, applied widely, and flange form pressure gauge debugging efforts can be made simple
Listization and standardization, effectively improve working efficiency；Construction cost has been saved while improving debugging efforts efficiency, and has been obtained
Good economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
In figure: 1- pressure meter calibration stand, 11- master gauge, the first jointing of 12-, 2- by school flange pressure table,
3- companion flange, 4- bolt, the second jointing of 5-, 6- conduit, support frame -7.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
The structure of the flange pressure table calibration equipment of the present embodiment is as shown in Figure 1 comprising pressure meter calibration stand 1, pressure
It is equipped with master gauge 11, another side on one side equipped with the first jointing 12, the flange pressure of the present embodiment on table checking table 1
Table calibration equipment further includes the companion flange 3 below the flange that flange pressure table 2 is arranged in, companion flange 3 and flange pressure
The flange size of table 2 is identical, and companion flange 3 is connected by bolt 4 with the flange of flange pressure table 2, under the companion flange 3
Side is equipped with support frame 7.Support frame as described above 7 is formed by stainless steel tube welding production, and the companion flange 3 is placed on support frame 7
Portion.The second jointing 5 is equipped with below the companion flange 3,3 center of companion flange is equipped with nipple orifice, and the second jointing 5 is solid
It is scheduled in nipple orifice, the second jointing 5 is connect by conduit 6 with the first jointing 12.3 center of companion flange connects
Head bore is threaded hole, and the upper end of second jointing 5 is equipped with the external screw thread cooperated with threaded hole.
