Description
Technical field
The present invention relates to a kind of medicine equipment, and in particular to a kind of delicate flow adjusting means.
Background technology
US5234413 describes a kind of equipment for carrying out rate of flow of fluid regulation in medical line.The equipment includes two
Individual coupling component, is provided with annular seal element between two coupling components.One component has dispenser, and dispenser is provided with
The groove of the section-variable of through hole is connected to, dispenser is connected with the original paper for making it be couple to fluid line in itself.Annular
Potted component has aperture, and the aperture makes can between the groove and the aperture being arranged in another component of the equipment
Connect, and the aperture in another component is connected thereto the connector for another pipeline for being connected with medical line.
Potted component has very flat opposed surface, and potted component only inserts into a structure for being arranged at the equipment
In recess on part.Therefore, if the component axially with respect to withdrawing from each other, or on the region that they contact with each other
Fulcrum it is pivotably movable with respect each other, then containment member can not then provide suitable Fluid Sealing.Because potted component is inserted completely
Enter into its seat, thus the component it is any withdraw from or misplace can all enable fluid present in groove from the part
Coupled zone side leakage.
The equipment is by making two coupling components around its common axis of rotation line realization regulation fluid pivotably movable with respect each other
Flow, and potted component is between two coupling components, due to play sealing function to the fluid in groove, therefore close
Envelope element is necessarily close to the contact surface of component, thus in two coupling components regulation flow pivotably movable with respect each other, sealing
Element can produce larger frictional resistance to the rotation of component, so when in use, can be in potted component and the contact surface of groove
It is upper to add lubricant to reduce frictional resistance during rotation so that more laborsaving during regulation flow, but when fluid stream is sealed
After element surface, it is possible to lubricant is produced convergence, or be also possible in component rotation process potted component surface
Lubricant spreads to convergent manner, thus causes trench cross section to change, and then produces very big shadow to the precision of equipment regulation flow
Ring.
