[0031] Specifically, as Figure 1 shown, the gas-phase delivery path is used to deliver calibration gas. The gas-phase delivery path includes: a gas-phase delivery pipeline 11, a ball valve 12, and a flowmeter 13. The output end of the gas-phase delivery pipeline 11 is connected to the input end of the input path; the ball valve 12 is communicated with the gas-phase delivery pipeline 11; the flowmeter 13 is communicated with the gas-phase delivery pipeline 11.

[0032] Specifically, as Figure 1 shown, the liquid-phase delivery path is used to deliver calibration liquid and convert the calibration liquid into a gaseous state for delivery. The liquid-phase delivery path includes: a liquid-phase delivery pipeline 21, a needle valve 22, and an electric heating vaporization pressure reducing valve 23. The output end of the liquid-phase delivery pipeline 21 is connected to the input end of the input path; the needle valve 22 is communicated with the liquid-phase delivery pipeline 21; the electric heating vaporization pressure reducing valve 23 is communicated with the liquid-phase delivery pipeline 21.

[0033] Specifically, as Figure 1 shown, the input end of the input path is connected to the output end of the gas-phase delivery path and the output end of the liquid-phase delivery path, and is used to deliver calibration gas or gaseous calibration liquid. The input path includes: an input pipeline 31 and a pneumatic valve 32.

[0035] Specifically, as Figure 1 shown, the analyzer 4 is connected to the output end of the input path.

[0036] Furthermore, as Figure 1 shown, an advanced gas-liquid two-phase calibration system according to an embodiment of the present utility model further includes: a first three-way valve 5, and the first three-way valve 5 is connected to the input end of the input path, the output end of the gas-phase delivery path, and the output end of the liquid-phase delivery path. By the first three-way valve 5, the gas-phase delivery path is communicated with the input path, or the liquid-phase delivery path is communicated with the input path, so as to realize the delivery of calibration gas or calibration liquid.

In addition, the system is designed with full consideration of the convenience of maintenance, reducing the workload of daily maintenance, making the maintenance work simpler and faster, and effectively improving the operation efficiency and reliability of the overall system.
