Chromatographic test gas cylinder integrated device

Abstract

The invention provides a chromatographic test gas cylinder integrated device. The chromatographic test gas cylinder integrated device comprises a gas cylinder storage frame and a gas circuit connecting device, wherein the gas circuit connecting device is arranged on the gas cylinder storage frame; the gas cylinder storage frame comprises a plurality of gas cylinder storage tanks; each gas cylinderstorage tank is provided with a movable supporting plate used for supporting a gas cylinder; and a plurality of supporting plate mounting positions matched with the movable supporting plate are arranged in each gas cylinder storage tank at different heights; and the movable supporting plate is detachably connected with any supporting plate mounting position in the corresponding gas cylinder storage tank. According to the chromatographic test gas cylinder integrated device, the gas cylinder storage frame can store the gas cylinders with different sizes and specifications, the use of the gas cylinders of different types in the same chromatographic test is met, moreover, each gas cylinder with the common size and specification can be well connected to the gas circuit connecting device afterstoring, in addition, the standard gas circuit connecting device is configured, the gas cylinders are convenient to switch, and consequently, the chromatographic test can be smoothly carried out.

Description

technical field [0001] The invention relates to the field of chromatographic test devices, more specifically, to a gas cylinder integrated device for chromatographic tests. Background technique [0002] In the electric power industry, transformer oil and SF6 gas chromatographic analysis test is an important test item. The test personnel often encounter the following problems when performing chromatographic tests: There are many types of gas used in the chromatographic test process, and the types and specifications of gas cylinders are different. Currently, the gas cylinders are placed The device can only place gas cylinders of the same specification. For example, Chinese patent CN209340871U discloses a new type of gas cylinder gas supply rack, which is used for combined gas supply of multiple gas supply cylinders; but when longer or shorter gas cylinders When the cylinder is placed in the gas cylinder rack, the bottle mouth of the gas cylinder cannot be in the correct connec...

AI Technical Summary

Problems solved by technology

[0003] The present invention overcomes the gas types used in the chromatographic test process described in the above-mentioned background technology, and the types and specifications of gas cylinders are different. The current device for placing gas cylinders can only place gas cylinders of the same specification. When longer or shorter gas cylinders When the bottle is placed in the gas cylinder rack, the bottle mouth of the gas cylinder cannot be in the correct connection position, which leads to inconvenient connection of the gas circuit during the chromatographic test and affects the progress of the chromatographic test. An integrated device for chromatographic test gas cylinders is provided.
