In other embodiment, the two-stage flow control layer may be replaced by three-level level flow control layer, four
Level flow control layer or Pyatyi or even above level flow key-course, it is cover plate, one-level flow control layer, secondary streams to set gradually
Amount key-course, three-level flow control layer and level Four flow control layer etc..
Further, the sealing of the multistage flow control structure and fixed work are strengthened for the ease of socket and further
With, on the cover board set an annular groove, according to itself and institute on two_stage flow key-course and above level flow key-course
State and be disposed with bulge loop and first annular groove in two planes on the direction of cover plate vertical range increase.Wherein, set
It is used to be socketed the bulge loop being arranged on one-level flow control layer in the annular groove on cover plate;It is arranged on flow control layers at different levels
Annular groove be used to be socketed and be arranged at bulge loop on the next stage flow control layer connected with it.
Further, it is multistage flow control provided by the present invention for being socketed on the flow control layer of container body opening
The flow control layer of the throttle orifice bore maximum on preparative layer, it is first annular groove with the joint of container.Further,
The first annular groove can do internal thread treatment, for strengthening the fixation between flow control layer and the opening of container body and close
Envelope is acted on.
A kind of multistage flow control structure provided by the present invention and container body are socketed, can be as one kind for holding liquid
The container of body material, by switching positioned at the bore of flow control layer upper limit head pieces at different levels, realizes in the when of falling liquid control flow
Purpose, has the advantages that safety, health, saving, practicality and intelligence.
Technical scheme is clearly and completely described below in conjunction with description of the invention accompanying drawing, it is clear that
Described embodiment is the preferred embodiment of the present invention, rather than whole embodiments.It will be appreciated by those skilled in the art that
