Description
Technical field
The utility model designs medical instruments field, specifically a kind of flow regulator.
Background technology
Traditional flow regulator is externally provided with pulley and limitation track in woven hose, by adjustable pulley on limitation track
The state that is extruded of position adjustments woven hose, so as to realize the control of liquid flowing speed in woven hose.This method accuracy compared with
Difference, can only be observed and be adjusted by the drop frequency of drop in doctor and nurse's observation transfusion funnel, both inaccurate or not
Convenient, for the less more accurate medicine of some consumptions, traditional flow regulator is not applied to more.
The setting of rubber cushion is the critical piece that flow regulator realizes function during flow regulator is adjusted, but is made
During, rubber cushion easily produces slip, so as to cause the through hole on inlet opening and rubber cushion effectively to dock, causes flow to adjust
Save device functional disturbance.
Therefore it provides a kind of precision is higher, indicative flow regulator more preferable, that operability is higher is current medicine instrument
The very active demand of field in the market.
Utility model content
The purpose of this utility model is to provide a kind of flow regulator, and especially its elastic mounting is firm.
The technical solution of the utility model is：A kind of flow regulator, including upper shell, lower house and rubber cushion, upper shell
Coaxially connected by connecting shaft between lower house, the end face of upper shell and the end face of lower house are oppositely arranged, and the rubber cushion is
Annular, rubber cushion is located between upper shell and lower house and around connecting shaft, and the end face of the upper shell is provided with inlet opening, rubber cushion phase
Fixed for upper shell, correspondence inlet opening is provided with through hole on rubber cushion, lower house is provided with the annular groove of width gradual change, the width of groove
End is provided with fluid hole, and through hole is engaged around the rotary motion trace of connecting shaft with annular groove, the end face pair of upper shell and lower house
Connect and form Flow-rate adjustment space, decoction enters inlet opening, the through hole docking of inlet opening and rubber cushion, medicine by the feed tube of upper shell
Liquid enters the end face of lower house by rubber cushion, and the difference of the through hole and the annular groove on lower house end face of rubber cushion is made by rotation
The part docking of width, realizes Flow-rate adjustment, and Flow-rate adjustment maximum position is that through hole is corresponding with the fluid hole of lower house.
The annular rubber cushion circumference is provided with fixed lobe and spacing preiection, and the end face of the upper shell is provided with retainer plate,
The retainer plate is provided with the fixed groove being engaged with fixed lobe and the limited impression being engaged with spacing preiection.Flow
Adjuster rubber cushion during use is relatively fixed with upper shell, coordinates the fixed lobe of rubber cushion using the retainer plate of upper shell
Rubber cushion can be made to keep being synchronized with the movement with upper shell, regulatory function is realized, spacing preiection then ensure that through hole on rubber cushion with entering
Fluid apertures is corresponding all the time, it is to avoid rubber cushion easily installs the deficiency of dislocation.
The line of the spacing preiection and through hole and the axis of connecting shaft intersect vertically.Spacing preiection and the collinear of through hole are set
Meter becomes apparent from the position of through hole, is that the failture evacuations such as through hole blocking are provided convenience.
The line of the limited impression and inlet opening and the axis of connecting shaft intersect vertically.Limited impression and inlet opening it is same
Line design then makes the corresponding relation of inlet opening and through hole definitely.
The width of the spacing preiection and the width ratio of fixed lobe are 2:1-3:1.The width of spacing preiection and fixation are convex
The ratio meaning of the width risen is that spacing demand should be met, and spacing preiection width is limited in into certain limit, is conducive to
Strengthen overall stability and reduce materials'use.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, flow regulator is installed
Stability it is higher.
