The switching valve structure 3 has a blocking part that can extend into the simulation part 10. The feeding structure 2 is also provided with a measuring part 11 communicated with the calibration air passage. The gas supply device 1 is communicated with a gas source device.

[0026] It should be noted that, as Figure 3 shown, the valve body 4 is installed on the feeding structure 2. The feeding structure 2 is arranged between the gas supply device 1 and the simulation part 10. The gas supply device 1 sends gas through the calibration air passage to the valve body 4 for ventilation calibration. The simulation part 10 has the same inner cavity structure as the valve body 4, maximizing the simulated gas flow area. By the way that the blocking part of the switching valve structure 3 extends into the simulation part 10, the opening and closing of the valve during the calibration process are carried out. The gas source device provides compressed gas to the gas supply device 1. The gas supply device 1 adjusts the gas. Calibration is carried out when the gas valve is not installed in the valve body 4, and unqualified products can be found in advance, so as to achieve faster and more accurate production.

[0027] In one embodiment, the feeding structure 2 is also provided with a positioning groove for installing the valve body 4 to fix the valve body 4.

[0028] In one embodiment, as Figure 3 shown, it further includes a bottom plate 6. The simulation part 10 is installed on the bottom plate 6. The bottom plate 6 is also provided with a support plate 7. The switching valve structure 3 is installed on the support plate 7 and is located above the simulation part 10. The blocking part in the switching valve structure 3 penetrates through the support plate 7 and extends into the simulation part 10, that is, the provided bottom plate 6 facilitates the installation of the support plate 7, so that the switching valve structure 3 and the simulation part 10 are arranged in the vertical direction.

[0029] Specifically, the blocking part is a piston rod, and its two ends are respectively arranged in the switching valve structure 3 and the simulation part 10, that is, the piston rod is used to move in the vertical direction to block the gas flow in the simulation part 10 and complete the opening and closing actions of the valve body 4 during the calibration process.

[0030] In one embodiment, as Figure 3 shown, it further includes a clamping device 5 connected to the bottom plate 6. The simulation part 10 and the clamping device 5 are respectively connected to two ends of the bottom plate 6.

[0031] Specifically, the clamping device 5 includes a clamping cylinder and a clamping rod.

[0032] In one embodiment, as Figure 1 and Figure 2 shown, it further includes a support platform 8. A plurality of air supply devices 1 are arranged on the support platform 8. Each air supply device 1 is sequentially connected to a plurality of material discharging structures 2 and a switching valve structure 3. A protective cover is also arranged on the support platform 8. The air source equipment is installed at the bottom of the support platform 8, that is, the provided support platform 8 can supply multiple valve bodies 4 for calibration at the same time. As Figure 1 shown, two air supply devices 1 are arranged on the support platform 8. Each air supply device 1 can supply air to multiple valve bodies 4 at the same time. The air source equipment is an air compressor, and the air compressor is arranged in the bottom box of the support platform 8.

[0033] In one embodiment, as Figure 1 shown, an installation platform 9 is further arranged on the outer edge of the support platform 8, and a plurality of material discharging structures 2 are arranged thereon. That is, the material discharging structures 2 arranged on the outer edge of the support platform 8 are convenient for preparation work. That is, when calibrating the previous batch of valve bodies 4, a new batch of valve bodies 4 can be arranged in the positioning grooves of the material discharging structures 2 on the installation platform 9. After the previous batch of valve bodies 4 is calibrated, the material discharging structures 2 between the air supply device 1 and the simulation part 10 are removed, and the positions of the material discharging structures 2 on the installation platform 9 are interchanged with them to improve the calibration efficiency.
