DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a portable flow controller with flow balance, comprising a flow pipe 1 and a flow controller body 2 vertically mounted on the top of the flow pipe 1, a mounting port 3 is opened on the top of the flow pipe 1, a mounting ring 4 is fixed to the mounting port 3, a docking locking assembly is fixed to the middle of the mounting ring 4, the docking locking assembly comprises a cover body 5, a locking ring 6, a reset ring 7, a floating ball 8 and a top cover 9, the cover body 5 is fixed to the middle of the mounting ring 4, the locking ring 6 is rotatably arranged at the upper end of the cover body 5, the locking ring 6 comprises a rotating ring 10, a limiting rod 11 and a stopper 12, the rotating ring 10 is rotatably arranged at the upper end of the cover body 5, the limiting rod 11 is divided into four groups, the outer end of the limiting rod 11 is fixed with a torsion spring 13, the torsion spring 13 is fixed on the rotating ring 10, the surface of the cover body 5 is provided with four groups of adjustment ports 14, the inner end of the limiting rod 11 is inserted into the adjustment port 14, the stopper 12 is fixed on the side wall of the adjustment port 14, the reset ring 7 is fixed to the bottom of the cover body 5, the floating ball 8 is embedded in the lower end of the detection end of the flow controller body 2, the floating ball 8 is built into the cover body 5 and the lower end is in contact with the reset ring 7, the top cover 9 is installed above the floating ball 8 and is used in conjunction with the locking ring 6.

[0018] Further improvement, such as Figure 2 As shown, an inlet 15 is provided at the upper end of the cover body 5 and an outlet 16 is provided at the lower end. The diameter of the inlet 15 is smaller than the diameter of the outlet 16 , so that the top cover 7 is conveniently placed in the cover body 5 .

[0019] Further improvement, such as Figure 3As shown: the reset ring 7 includes a bottom ring 17 and an elastic ring 18 fixed on the bottom ring 17. Several groups of elastic rings 18 are distributed in a stacked manner. The elastic rings 18 are in contact with the floating ball 8. The elastic rings 18 give the floating ball 8 an upward force, which facilitates the disassembly of the flow controller body 2.

[0020] Further improvement, such as Figure 2 As shown, the floating ball 8 is a hollow spherical structure, and the diameter of the floating ball 8 is smaller than the diameter of the introduction port 15 . This design is convenient for cooperating with the reset ring 7 to reset and adjust the floating ball 8 .

[0021] Specifically, the top cover 9 is a disc-shaped structure with a middle portion protruding upward, and the diameter of the top cover 9 is equal to the diameter of the introduction port 15 , so that the top cover 9 is easy to move into the introduction port 15 .

[0022] During use: When the flow controller body 2 needs to be disassembled and repaired, the staff can twist the rotating ring 10 counterclockwise. The rotating ring 10 drives the limit rod 11 to move synchronously during the rotation. When the limit rod 11 conflicts with the stop block 12, the inner end of the limit rod 11 tilts so that the inner end of the limit rod 11 moves into the adjustment port 14. At this time, the limit rod 11 is separated from the limit on the top cover 9. Under the elastic force of the reset ring 7, the floating ball 8 moves up, and the flow controller body 2 moves up and separates from the installation port 3, completing the disassembly. The operation is simple and easy to use.
