Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
The utility model provides a kind of micro flow regulating valve, as shown in Figures 1 to 4.The micro flow regulating valve, packet
The two-way valve body 1 for including bottom end setting, the rotation adjusting lever 2 being arranged with two-way valve body 1 and fixed locking turncap 3；Two-way valve body 1 wraps
The vertical connecting hole 12 for including the mainstream hole 11 opened up in the horizontal direction and opening up along the vertical direction, and opened on 11 lower end wall of mainstream hole
Equipped with limiting slot 13 corresponding with vertical connecting hole 12.
The lower end of rotation adjusting lever 2 is symmetrically offered perpendicular to the fluid slot 23 being axially arranged, and non-between fluid slot 23
Connection setting, the upper end of rotation adjusting lever 2 is equipped with positive stop lug boss 21, and the outer diameter of positive stop lug boss 21 is greater than vertical connecting hole 12
Diameter, rotation adjusting lever 2 is vertically inserted into vertical connecting hole 12 and directes reach in limiting slot 13, positive stop lug boss 21 with vertically connect
The upper end in hole 12 abuts, and rotation adjusting lever 2 is free to rotate in vertical connecting hole 12.
Fixed locking turncap 3 covers at the periphery of rotation adjusting lever 2, and passes through the hand-held part 24 of 2 upper end of rotation adjusting lever,
And rotation adjusting lever 2 is limited between fixed locking turncap 3 and two-way valve body 1, and the lower end and two of fixed locking turncap 3
