Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
In description of the present utility model, it is to be understood that the orientation of the instruction such as term " on ", " under ", "left", "right"
Or position relationship is based on orientation shown in the drawings or position relationship, is for only for ease of description the utility model and simplification is retouched
State, rather than instruction or imply signified device or element there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not intended that to limitation of the present utility model.
Referring to Fig. 1 to Fig. 3, water flow regulating device described in this preferred embodiment includes hollow fixes sleeve 2 and embedding
Elastic inner core 1 inside the fixes sleeve 2, one end of the fixes sleeve 2 are water inlet 26, the fixes sleeve 2
The other end be delivery port 27, the elastic inner core 1 is provided with several and is used for the first passage 11 that stream passes through that supplies water, described the
The both ends of one passage 11 are connected with the water inlet 26 and delivery port 27 of the fixes sleeve 2 respectively.
Based on above structure, when carrying out current regulation using the device, the device is installed on inside water pipe, water flows into
After in oral siphon, flow through fixes sleeve 2 and enter in elastic inner core 1, water-carrying capacity is carried out by elastic inner core 1 defeated after effectively adjusting
Go out, so that for users to use, when the water flow pressure in water pipe is larger, elastic inner core 1 is located at the water inlet 26 of fixes sleeve 2
Acted on end face by the pressure, make elastic inner core 1 that certain deformation occur, the elastic inner core 1 after deforming upon can be to two
Side is stretched, and due to constraining for the inwall by both sides fixes sleeve 2, elastic inner core 1 can not continue to expand to both sides, in pressure
Under effect, elastic inner core 1, which is forced internally to shrink, to be extruded first passage 11, causes the cross-sectional area in first passage 11
Diminish, so as to which water-carrying capacity is reduced, the phenomenon of user's unexpected current increase when with water is avoided the occurrence of, when the current in water pipe
When pressure progressively reduces, elastic inner core 1 is located at the pressure effect being subject on the end face at the water inlet 26 of fixes sleeve 2 also progressively
Reduce, elastic inner core 1 is no longer progressively recovered by external force effect shape, the cross-sectional area reduction in first passage 11, and water-carrying capacity is extensive
It is multiple normal, by the deformation quantity of elastic inner core 1, realize under different water flow pressures, the stable effect for exporting water-carrying capacity.
It should be noted that in the present embodiment, the material of elastic inner core 1 is preferably quality of rubber materials, elasticity preferably, is realized
The effect of regulating water flow is very reliable, but in other embodiments, the material of elastic inner core 1 is selected not by the present embodiment
Limitation, when can according to reality needs, select suitable material.The overall structure of the device is very simple, and principle is reliable,
It need not manually adjust, realize the regulation of water-carrying capacity automatically, it is convenient and applied widely to manufacture.
