AI Technical Summary

Technical Problem

In existing technologies, chromatography columns cannot be continuously pressurized for extended periods during power outages, affecting the stability of pressurization and chromatography efficiency.

Method used

A continuous pressurization device is designed, including an air bladder, an air outlet, an air inlet, a connecting assembly, and a locking assembly. The air bladder stores gas and provides continuous air pressure in the absence of power. The connecting assembly ensures stable gas transmission, and the locking assembly prevents loosening and ensures the stability of pressurization.

Benefits of technology

It enables continuous pressurization for extended periods without power, improving the chromatography efficiency of the column. It is easy to use and inexpensive, avoiding problems such as pressurization interruption and depressurization.

Abstract

The utility model discloses a continuous pressurizing device which comprises a continuous pressurizing assembly which comprises an air bag, an air outlet head communicated with the bottom face of the air bag, an air inlet head communicated with the side face of the air bag and a to-be-tested instrument tube arranged below the air bag. A connecting assembly, the connecting assembly comprises a round pipe arranged below the air outlet head, a threaded pipe communicating with the round pipe, a first groove opening formed in the outer wall of the round pipe, a connecting pipe arranged below the threaded pipe, a first internal thread formed in the connecting pipe, an annular baffle fixed to the outer wall of the connecting pipe and a conical connector communicating with the connecting pipe. The air inlet pipe is arranged at the air inlet head; and the valve is connected with the air inlet pipe. According to the utility model, the continuous pressurizing assembly and the connecting assembly are matched with each other, so that long-time continuous air pressure can be provided under the condition of no power supply, even if air inlet is interrupted, continuous pressurizing can still be ensured, the use is convenient, the cost is low, and the chromatography efficiency of the chromatographic column is improved.
