The utility model discloses a movable fuel gas pressure regulating metering pry, which comprises a movable frame, a movable rod, supporting blocks, a first rectifier and a second rectifier, one side of the first rectifier and one side of the second rectifier are fixedly connected with limiting blocks, two sides of the upper end of the movable frame are fixedly connected with supporting frames, the limiting blocks are connected with the supporting frames in a sliding manner, and the movable rod is fixedly connected with the movable frame. The movable rod is movably connected to the interior of the supporting frame through a bearing, first thread lines are arranged on the outer wall of the movable rod, the limiting block is meshed with the outer wall of the movable rod in a threaded mode, and plastic buckles are arranged in the supporting block in a circumferential array mode. According to the utility model, the first inclined surface and the second inclined surface are mutually rubbed by rotating the fastening bolt, and the plastic buckles are close to each other under the thrust of friction to clamp the movable rod, so that the movable rod is limited and fixed, and the second rectifier and the first rectifier are stably fixed; and the connection between the gas pipeline and the gas pipeline can be ensured.

This invention belongs to the field of liquid chromatography technology, specifically a connector module and a liquid chromatography column. One of the upper and lower connectors of the connector module is fixedly assembled with the liquid chromatography column. Both the upper and lower connectors include a mounting base, a valve core, and a valve sleeve. The valve sleeve is elastically nested outside the valve core. Both the valve core and the valve sleeve have a transition section with a conical mating surface. When the valve sleeve is in an elastic pre-tightened state, the conical surface of the transition section is tightly sealed, ensuring a tight seal, suitable for normal sealing of the liquid chromatography column. During docking, the upper and lower connectors are pressed together, sealing the two valve sleeves and creating a liquid-guiding gap by separating the conical surfaces of the transition section. This allows for convenient and effective sealing and connection of the liquid-guiding channels of the upper and lower connectors. This invention improves the convenience of maintenance and replacement operations of the liquid chromatography column, facilitates automation, and ensures a tight seal, guaranteeing production safety.

The present application belongs to the technical field of gas supply system, especially to the gas container gas supply system and method, the system comprises a plurality of storage cavities, the storage cavity is provided with a clamping mechanism, the mechanism can exert vertical pressure from the bottle shoulder and simultaneously clamp from the side, realize the stable fixation of the gas storage tank, the round groove is provided with a connecting head, the outer wall of the gas storage tank valve handle is provided with a clamping groove, the outer wall of the gas outlet end is provided with a fixing ring with a specific shape insertion hole, the matching mechanism comprises a pin rod which can be inserted into the clamping groove, only when the mounting ring at the bottom of the connecting head and its pressure rod and the insertion hole of the fixing ring are correctly matched and pressed, the pin rod can be driven to rotate and separate from the clamping groove, allowing the valve handle to open, thereby preventing gas connection error, the gas supply system improves the stability of the fixation of the gas storage tank, avoids gas misconnection, and enhances the adaptation ability of the output interface.
