In cylinder；
End cap is equipped with the upper surface of said base；
Regulating part can be movably set on end cap above-mentioned from outer to inner, and inner end offsets with connecting bracket above-mentioned, outside
End forms adjustable side；
First spring one end and offsets with circuit board on said base and forces circuit board to be held away from pedestal always
Trend；
Nonreturn valve core is located at the lower end of said base, which forms inner cavity, which is equipped with magnet
And it is placed on the outside of aforementioned cylinder and can move back and forth with respect to cylinder；And
Second spring offsets set on the upper surface of the lower end of said base and one end and nonreturn valve core and forces always unidirectional
Spool is held away from the trend of pedestal.
Further, the magnet is arranged in a ring and around cylinder.
Further, the lower end of the pedestal extends downward with sleeve part, and the cylinder is located at sleeve part center, institute
The second spring stated then is located in sleeve part.
The port that the pedestal upper end is located at cylinder is equipped with guide cylinder, and the circuit board and connecting bracket are then located at should
In guide cylinder.Guide cylinder can ensure that connecting bracket stress equalization is stablized.
Preferably, the regulating part is adjusting screw, accordingly, there is interconnecting piece, in the interconnecting piece on the end cap
Side is molded the internal thread with the cooperation of aforementioned adjusting screw.
Compared with prior art, the utility model has the advantage of：Adjustment regulating part makes tongue tube move up and down to reach
It is adjusted at a distance from magnet, and then the uninterrupted of water, compact-sized, operation side is controlled by controlling the distance of nonreturn valve core
Just quick.
Description of the drawings
Fig. 1 is example structure schematic diagram.
Fig. 2 is embodiment sectional view.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As depicted in figs. 1 and 2, the water pump adjustable flow sensor in the present embodiment include pedestal 7, circuit board 6, end cap 9,
Regulating part 10, the first spring 5, nonreturn valve core 1 and second spring 2.
Pedestal 7 extends downwardly the cylinder 72 of Single port upward；6 upper end of circuit board is equipped with a connecting bracket 8, and lower end is downward
Extend and be equipped with tongue tube 4, which is plugged in cylinder 72.
End cap 9 is equipped with the upper surface of pedestal 7；Regulating part 10 can be movably set on end cap 9 from outer to inner, inner end and company
It connects holder 8 to offset, outer end forms adjustable side.
First spring 5 is set to one end on pedestal 7 and offsets with circuit board 6 and circuit board 6 is forced to be held away from pedestal 7 always
Trend；Nonreturn valve core 1 is located at the lower end of pedestal 7, which forms inner cavity, which is equipped with magnet 3 simultaneously
It is placed on 72 outside of cylinder and opposite cylinder 72 can move back and forth；Magnet 3 in the present embodiment is arranged in a ring and around cylinder 72.
Second spring 2 is set to the lower end of pedestal 7 and one end and the upper surface of nonreturn valve core 1 offset and force check valve always
Core 1 is held away from the trend of pedestal 7.
Further, the lower end of pedestal 7 extends downward with sleeve part 71, and cylinder 72 is located at 71 center of sleeve part, and second
Spring 2 is then located in sleeve part 71.The port that 7 upper end of pedestal is located at cylinder 72 is equipped with guide cylinder 73, circuit board 6 and connection branch
Frame 8 is then located in the guide cylinder 73.
Regulating part 10 in the present embodiment is adjusting screw, accordingly, has interconnecting piece 101, the interconnecting piece on end cap 9
