Figure 2 and Figure 4 In a specific embodiment, threaded through holes 531 are provided at both ends of the mounting block 530, and threaded holes 191 are provided at both sides of the end of the first slide groove 190. By screwing bolts into the threaded through holes 531 and the threaded holes 191 in sequence, the mounting block 530 can be fixed to the mounting table 110. This not only ensures the stability of the installation, but also facilitates the installation and removal of the pressing structure 500.

[0036] Please refer to Figure 4 The first electric telescopic rod 510 is arranged on the mounting block 530, the bottom of the vertical rod 550 has a first slider 551, the first electric telescopic rod 510 can drive the first slider 551 to move horizontally in the first slide groove 190, the vertical rod 550 has a second slide groove 553 along the length direction, the second electric telescopic rod 570 is fixed to the vertical rod 550, one end of the pressing plate 590 has a second slider 591, the second electric telescopic rod 570 can drive the second slider 591 to move vertically in the second slide groove 553, and the end of the pressing plate 590 away from the second slide groove 553 has a pressing portion 593.

[0037] In a specific embodiment, please continue to refer to Figure 4 The first slide groove 190 and the second slide groove 553 are both set as T-shaped slide grooves, and the first slider 551 and the second slider 591 are both set as corresponding T-shaped sliders, which can make the movement of the first slider 551 in the first slide groove 190 and the second slider 591 in the second slide groove 553 more stable.

[0038] See also Figure 4 A specific implementation method is to stick a second anti-slip pad 595 on the side of the pressing portion 593 close to the flange base 300, so that the pressing portion 593 can press the flange of the flange pressure gauge more stably.

[0039] The specific working principle of the flange pressure gauge downward pressure calibration table 10 provided by the utility model is as follows: when the flange pressure gauge needs to be calibrated, first, the mounting base 100 is stably placed on the work surface, and then the internal threaded connecting pipe 310 on the flange base 300 is inserted into the through hole 170 in the center of the mounting surface 110, and the flange base 300 is embedded in the circular groove 150 of the mounting surface 110; two pressing structures 500 are taken out from the storage container, and the two first sliding blocks 551 and the mounting block 530 are respectively inserted into the two first sliding grooves 190 arranged diagonally, and the vertical rod 550 can be fixed to the mounting surface 110 by screwing the bolts into the threaded through holes 531 on the mounting block 530 and the corresponding threaded holes 191 on the mounting surface 110 in turn and tightening them.

[0040] Then, place the flange of the flange pressure gauge to be tested on the flange base 300 so that the vent hole of the flange pressure gauge corresponds to the internal threaded connecting pipe 310. At the same time, adjust the two corresponding pressing structures 500, and according to the diameter of the flange pressure gauge to be tested, start the first electric telescopic rod 510 to drive the first slider 551 to move horizontally in the first slide groove 190, so that the vertical rod 550 drives the pressing plate 590 to move horizontally until the pressing plate 590 is located above the edge of the flange. Start the second electric telescopic rod 570 to drive the second slider 591 to move vertically in the second slide groove 553, thereby driving the pressing plate 590 to move toward the flange until the pressing part 593 is pressed tightly against the flange.

[0041] After the gas supply pipe of the calibration equipment is tightly connected to the internal threaded connecting pipe 310, ventilation calibration is performed, and the indication of the standard pressure gauge is compared with the indication of the flange pressure gauge to be inspected. After the inspection is completed, the flange pressure gauge to be inspected is removed to complete the inspection process. Start the second electric telescopic rod 570 to drive the pressing plate 590 to move away from the flange until the pressing part 593 is away from the flange, and the flange pressure gauge is removed. By removing the bolts, the pressing structure 500 can be removed from the mounting table 110 for storage.

[0042] It should be noted that the specific models and specifications of the first electric telescopic rod 510 and the second electric telescopic rod 570 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
