Embodiment
The utility model discloses a kind of flow regulator, inhomogeneous to prevent the irrigation that takes place because of hydraulic pressure is excessive, the phenomenon at waste water source.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1-Fig. 4, the structural representation of the flow regulator that Fig. 1 provides for the utility model embodiment, the plan view of the Flow-rate adjustment passage that Fig. 2 the utility model embodiment provides, the polycrystalline substance schematic representation of the Flow-rate adjustment passage that Fig. 3 the utility model embodiment provides, deformation shell fragment that Fig. 4 the utility model embodiment provides and plan view after funnel-shaped passage contacts.
Wherein, 1 is intake tunnel, and 2 are the deformation shell fragment, and 3 is fixing column, and 4 is tank, and 5 is filter screen, and 6 is exhalant canal, and 7 is the tank top; 8 is the tank bottom, and 9 is funnel-shaped passage upper end inwall, and 10 is funnel-shaped passage lower end inwall.
The flow regulator that the utility model provides comprises intake tunnel 1, Flow-rate adjustment passage, deformation shell fragment 2 and exhalant canal 6.Wherein, intake tunnel 1 and exhalant canal 6 are connected to the two ends of Flow-rate adjustment passage.The Flow-rate adjustment passage is connected the lower end of described intake tunnel 1, the tank 4 that this Flow-rate adjustment passage comprises funnel-shaped passage and is positioned at this funnel-shaped passage outside.Deformation shell fragment 2 is arranged on the upper end of described funnel-shaped passage by fixing column 3, has the gap between the top of this deformation shell fragment 2 and described funnel-shaped passage, by enter the pressure difference of water by intake tunnel 1, deformation can take place in deformation shell fragment 2, thereby change the distance on deformation shell fragment 2 and funnel-shaped passage top, thereby change the area of funnel-shaped passage water inlet.Exhalant canal 6 is connected the lower end of described Flow-rate adjustment passage.
The utility model is provided with the Flow-rate adjustment passage between intake tunnel 1 and exhalant canal 6, and this Flow-rate adjustment passage tank 4 of comprising funnel-shaped passage and being positioned at this funnel-shaped passage outside, and in the upper end of funnel-shaped passage deformation shell fragment 2 is set.During irrigation, water enters the Flow-rate adjustment passage by intake tunnel, deformation this moment shell fragment 2 is subjected to hydraulic pressure generation elastic strain in various degree, change the gap of funnel-shaped passage top and deformation shell fragment 2, thereby regulate water flow, when hydraulic pressure increases to a certain degree, deformation shell fragment 2 closely contacts with the funnel-shaped passage top, current can only flow out from tank, have prevented that the irrigation that takes place because of hydraulic pressure is excessive is inhomogeneous, the waste water source.
Deformation shell fragment 2 is preferred (the most handy passable herein, because the material of unqualified deformation shell fragment in the superincumbent description, be the latex shell fragment if say deformation shell fragment 2 herein, if others is with the deformation shell fragment 2 of other materials so, and is passive with regard to some concerning us, if parts can be used unlike material, advise so in specification with can or preferably waiting speech) be the latex shell fragment, elasticity is splendid, and is capable of washing, durable in use.Fixing column 3 can be four, and is evenly distributed on the circumference of described deformation shell fragment 2.Fixing column 3 also is preferably the latex fixing column, makes fixing column 3 have elasticity equally, the sensitivity of the Flow-rate adjustment of raising.
