Description

Technical Field

[0001] The utility model relates to the technical field of through-pipe joint components, in particular to a multi-way sealing joint for gas quality detection in a gas storage cylinder. Background Art

[0002] Gas quality detection is mainly carried out through gas detectors, which convert the physical or chemical non-electrical signals collected by gas sensors into electrical signals, and then rectify and filter the electrical signals through external circuits. The processed signals are used to control the corresponding modules to achieve gas detection. The gas quality of the gas cylinder is detected by connecting the gas cylinder to the gas detector. Usually, a multi-way sealing connector is used to connect the gas cylinder and the gas detector.

[0003] Patent No. CN202221169398.8 proposes a multi-way pipe sealing joint, which is achieved by buckling the connecting plate on the second connecting pipe onto the connecting head. At this time, the connecting block is inserted into the connecting groove for preliminary installation and connection, and then the screw is driven to rotate by the rotating block, thereby pushing the card block to move out of the telescopic groove and insert it into the inclined groove to strengthen the connection effect. The card block is gradually inserted into the inclined groove to squeeze the connecting plate, which makes it easy to drive the connecting plate to gradually move toward the connecting head, thereby improving the firmness of the overall connection. There are too many steps in the connection process, which is not convenient for quick connection, and it cannot quickly act on the gas quality detection operation. Therefore, the technical personnel in this field provide a multi-way sealing joint for gas quality detection of gas storage cylinders to solve the problem that there are too many steps in the connection process, which is not convenient for quick connection, and it cannot quickly act on the gas quality detection operation.
