Gas chromatography gas sample injector for analysis and assay of oil refinery

The utility model provides a gas chromatography gas sample injector for analysis and test in an oil refinery, which comprises a sample injection box, a sample feeding mechanism is arranged in the sample injection box, and a gas inlet is formed in the sample feeding box. The sample feeding mechanism comprises a chromatographic detector, an integrated box, a first driving motor, a first rotating wheel, a first fixing block, a first connecting block, a first transmission block, a fixing frame and a sampling needle head, one side of the integrated box is fixedly connected with one side of the first driving motor, and the bottom of the first transmission block is fixedly connected with the top of the fixing frame. The gas chromatograph gas sample injector for analysis and test in the oil refinery solves the problems that a medical needle cylinder and a manual sample injection mode are used in gas sample extraction and sample injection links, so that a test result has large fluctuation, the objectivity of an analys
