Abstract
The invention provides a labyrinth type elastomer flow controller which is formed integrally from elastomer material. The labyrinth type elastomer flow controller comprises an elastic adjusting ring and a control gap which can change under the pressure of passing fluid is defined between the elastic adjusting ring and a shell wall. The labyrinth type elastomer flow controller comprises at least one water inlet or a pair of water inlets and also comprises at least one water outlet or a pair of water outlets. At least one labyrinth type bypass channel or a pair of labyrinth type bypass channels is arranged between the water inlet(s) and the water outlet(s). The labyrinth type elastomer flow controller is made of elastomer material; with the rise of the pressure, the adjusting ring deforms because of stress and the control gap narrows, so that the objective of flow control is achieved. The labyrinth type elastomer flow controller has the advantages of more stable flow and smaller noise.
Description
Technical field
The present invention relates to a kind of flow dontroller, particularly a kind of adopt elastic material prepare and bypass passageways adopt mazy type arrange flow dontroller.
Background technique
Inventor is in patent comparatively early: disclose a kind of mazy type flow controller in 2013100268398, labyrinth is adopted to control the fluid flow by this passage as bypass passageways in the above-mentioned mazy type flow controller disclosed, obtain preferably flow curve and less noise, inventor has been noted that, the method is adopted to carry out flow control, along with the rising of pipeline pressure, control gap cannot realize better reducing, and causes flow curve still to have certain increase along with pressure increase.
Summary of the invention
By labyrinth elastic body flow dontroller of the present invention, above-mentioned shortcoming can be solved, thus realize other advantage being about to description.Labyrinth elastic body flow dontroller of the present invention, adopts elastomer material one-body molded, comprises a flexible adjustment ring, limit a control gap changed under the hydrodynamic pressure flow through between this flexible adjustment ring and shell body wall, thus realize the control to flow.
Object of the present invention reaches by following technical solution:
A kind of labyrinth elastic body flow dontroller, adopt elastomer material one-body molded, comprise a flexible adjustment ring, a control gap changed under the hydrodynamic pressure flow through is limited between this flexible adjustment ring and shell body wall, it is characterized in that: described labyrinth elastic body flow dontroller is configured with at least one or a pair water intake, described labyrinth elastic body flow dontroller is also configured with at least one or a pair water outlet, is configured with at least one or a pair mazy type bypass passageways between described water intake and water outlet.
Be the cavity of back-end closure in the middle of described labyrinth elastic body flow dontroller, described flexible adjustment ring arranges cavity end.
Described flexible adjustment ring is thin walled structures.
The described flexible adjustment ring being arranged to thin walled structures can overcome restoring force dilatancy along with the rising of pipeline pressure.
Described mazy type bypass passageways is made up of some sealed muscles to cross setting and the raised tooth be arranged between sealed muscle.
The path clearance formed between described raised tooth is identical.
Described raised tooth can be triangle, trapezoidal, the shape such as rectangular or class triangle.
Described control gap limited by flexible adjustment ring and shell body wall.
The present invention contrasts prior art following remarkable advantage:
1. adopt elastomer material one-body molded, cost is low, and manufacturing efficiency is high;
2. limit a control gap changed under the hydrodynamic pressure flow through between flexible adjustment ring and shell body wall, regulating ring along with pipeline pressure rising expand larger, this is that control gap is less, stability of flow;
3. bypass passageways designs for mazy type, lengthens its channel distance, reduces pressure.

Embodiment
Now the present invention is further described with embodiment by reference to the accompanying drawings.
Basic ideas of the present invention limit a control gap changed under the hydrodynamic pressure flow through between flexible adjustment ring and shell body wall, thus realize the control to flow.
Shown in figure 1,2,3,4,5,6, the labyrinth elastic body flow dontroller 1 of different embodiment, it can be installed in the front position preset of here unshowned sanitary equipment, flow through ducted fluid in this unshowned sanitary equipment first by described labyrinth elastic body flow dontroller 1 after at the miscellaneous part flowing into this sanitary equipment.
Even if the maximum value of labyrinth elastic body flow dontroller 1 for this reason for also the flow control flow through in time per unit being specified one when the pressure of increasing incoming fluid, labyrinth elastic body flow dontroller 1 adopts elastomer material one-body molded for this reason, it comprises a flexible adjustment ring 2, a control gap changed under the hydrodynamic pressure flow through 4 is limited between this flexible adjustment ring 2 and shell body wall 3, Fig. 3, it is the cavity 10 of endcapped in the middle of the body of labyrinth elastic shown in 5 flow dontroller 1, the regulating ring 2 being arranged at its end is deformed to profile under the hydrodynamic pressure flowed into always, and make control gap 4 narrow simultaneously.
For labyrinth elastic body flow dontroller is configured with at least one or a pair water intake 5, described labyrinth elastic body flow dontroller 1 is also configured with at least one or a pair water outlet 6, at least one or a pair mazy type bypass passageways 7 is configured with between described water intake and water outlet, described bypass passageways 7 is made up of some sealed muscles 8 to cross setting and the raised tooth 9 be arranged between sealed muscle, adopts the bypass passageways 7 of mazy type design to extend the runner distance flowing through fluid as far as possible.
In another embodiment shown in Fig. 6, when not being provided with filtration system in the sanitary equipment front end of installing this labyrinth elastic body flow dontroller 1 or pipeline, this labyrinth elastic body flow dontroller 1 front end can arrange a sieves 11 and filter.
The working method of labyrinth elastic body flow dontroller of the present invention is: this labyrinth elastic body flow dontroller 1 is installed in the default front position of sanitary equipment and is sealed by sidewall, flowing through this equipment when there being fluid is, fluid first flows in cavity 10, now flexible adjustment sheet 2 is subject to hydrodynamic pressure and realizes distortion, control gap 4 changes, fluid is by flowing into mazy type bypass passageways 7 after water intake 5 simultaneously, then enters from water outlet 6 outflow the miscellaneous part that bypass passageways 7 finally flows into sanitary equipment.
Therefore, even if labyrinth elastic body flow dontroller of the present invention well can not only guarantee the maximum value that also flow control flow through in time per unit can be specified when the pressure of increasing incoming fluid, and adopt elastomer material one-body molded, the control of noise can well be realized.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
