BRelation.And V
BBe again to be directly proportional with the flow velocity of the liquid of input duct.So the flow of the liquid medicine that is come out by the drug through hole at cover plate center is to be directly proportional with the flow of the liquid of input duct.That is to say that when the changing of the flow of the liquid that flows through trunk line, the flow of the influent stream pipeline of this device also changes thereupon, and the flow of drug through hole is also changed thereupon, thus the ratiometric substantially constant of the medicament that has added in having guaranteed to be responsible for.
Described eddy current forms structure and can be made of the baffle plate that a radial line with the column drug reservoir that is fixedly arranged on input duct liquid outlet place is an angle.This baffle plate can be fixed on the inwall of column drug reservoir, also can be fixed on the exit end face of input duct, even by the exit end of input duct establish one the bending fritter constitute baffle plate.
Also can constitute eddy current and form structure by a fluid pipeline section of laying at an angle with the radial line of column drug reservoir.More simple directly way is directly the radial line of input duct and column drug reservoir to be an angle to be connected to the column drug reservoir.
Influence that the fluidised form of bottom medicament chamber is produced for the vortex motion that alleviates whirl chamber and the medicament that makes the bottom be not by the very fast dissolving of the liquid on top, can do the medicament cover plate thicker, experimental results show that the thick more diffusion motion that can stop the bottom medicament more that cover plate is done toward top.Enter in the medicament chamber of bottom through this guide groove and enter whirl chamber from the drug through hole behind the pharmaceutical dissolution offering liquid that some uniform axially directed grooves also are of value to vortex edge, top on the sidewall of cover plate.
Consider and when stopping using, avoid containing certain density liquid medicine because of flowing in the trunk line in the column shape container top, one section " U " type bending tube section can all be set on the liquid inlet and outlet pipeline than great.
The utility model compared with prior art has following advantage: 1, and dosing dosage is automatically with flowrate variation.At flow, when pharmaceutical quantities changes, adding consistency kept stable, the pressure independent of liquid in adding consistency and the trunk line.
2, the adjusting of adding consistency is very convenient.The medicament cover plate in hyperphoric different apertures, valve forms structure with the eddy current between ratio, input duct and the column shape container of regulating shunting adjustment is set on feed tube is logical all can realizes regulating adding consistency with the formation situation that changes eddy current.
3, the setting of medicament cover plate has alleviated medicament diffusion influence degree greatly, provides assurance for adding medicament in proportion.
