Description
Technical Field
[0001] This utility model relates to the technical field of adjustable flow channel connecting pipe fittings, and in particular to an adjustable tee connector. Background Technology
[0002] In the field of adjustable flow channel connection pipe fittings, tee fittings are widely used in the transmission systems of various media such as liquids and gases as key components for material diversion and conveying. However, existing tee fittings have significant defects in terms of flow channel control and ease of operation, making it difficult to meet the needs of practical applications. Most existing T-joints have rudimentary adjustment structures that cannot achieve independent and precise control of the two discharge ends. They either only control the overall flow channel, failing to differentiate the flow rate at different discharge ends, or their adjustment mechanisms have poor linkage, leading to frequent jamming during operation and difficulty in quickly responding to material distribution needs, making them unsuitable for diversion requirements in various scenarios. Furthermore, existing T-joints with adjustment functions generally lack intuitive feedback mechanisms for adjustment status. Operators cannot directly obtain information about the rotation angle of internal flow-blocking components and the corresponding flow channel's on / off status and flow rate during adjustment, requiring additional flow detection tools for confirmation. This not only increases operational steps and time costs but also easily leads to inaccurate control due to judgment errors, severely impacting operational efficiency and potentially causing abnormal material conveying due to improper adjustment. Therefore, these problems need to be addressed. Utility Model Content

[0016] Working principle: When using this utility model, the operator connects the external connecting pipe with raw rubber tape to the three-way pipe 1 through the feed end 2, the first discharge end 3, and the second discharge end 4 respectively. After the connection is completed, the external connecting pipe connected to the feed end 2 is opened, and the first discharge end 3 and the second discharge end 4 are checked for liquid leakage. The time should be controlled within five minutes. The sliding groove 6 is observed for liquid leakage. The above steps are to check the sealing performance of the first sealing ring 8 and the second sealing ring 9 connected to the butterfly plate 7. Then, the operator can turn the knob 11 according to different scenario requirements. Turning the knob 11 will drive the screw 12 connected to the positioning plate 10 to rotate. The rotation of the screw 12 will drive the moving plate 13 to move. The movable plate 13 is hinged to the first hinge rod 14, and the first hinge rod 14 is hinged to the connecting rod 15. The connecting rod 15 is fixed to the butterfly plate 7 and to the second hinge rod 16. The second hinge rod 16 is slidably connected to the third hinge rod 18 through a spring in the built-in drive chamber. The third hinge rod 18 is hinged to the display block 17. Therefore, the movement of the movable plate 13 will drive the movable plate 13 to move, thereby driving the first hinge rod 14 to move. As the movement increases, it will drive the butterfly plate 7 to rotate through the connecting rod 15. During the rotation of the connecting rod 15, it will drive the second hinge rod 16 to rotate, thereby driving the third hinge rod 18 to rotate, causing the display block 17 to move in the sliding groove 6, so that the external operator can observe the rotation angle of the butterfly plate 7 with the arc groove opened at the lower front end of the protective cover 5.
