The utility model is characterized in that a connecting tube us a hollow tube body, both ends are provided with screw thread, and a tube wall is arranged on an inner wall near one end of the connecting tube; the control valve is a hollow tapered body placed in the connecting tube, and both ends of the control valve are respectively provided with an upward-projected ring and a downward-projected ring; the upward-projected ring extends upwards to form a central water outlet and a tapered surface, and the tapered surface corresponds to the tapered tube wall of the connecting tube; a plurality of water outlet holes are arranged on the control valve, and a spring sleeve is placed on the control valve; the tubular cover is connected with the bottom of the connecting tube. No matter how the water flow or the water pressure changes, the total water output of the water which flows through the water flow automatic-control valve is a constant value.
Description
The utility model relates to measuring appliance, refers to a kind of water flow autocontrol valve especially.
In society now, the building stands in great numbers, the shared building water storage box of several hundred families, when using the user more after a little while, inflow is abundant in the conduit pipe in every household, it is sufficient to supply water, otherwise conduit pipe hydraulic pressure and water output successively decrease, and when especially needing hot water using water heater, the user often will constantly adjust the switch of water tap according to the size of water flow, otherwise can scald human body, this to the user brought inconvenient and psychology because of disturbing.
The purpose of this utility model is: provide a kind of size that adapts to flow of inlet water or hydraulic pressure to control the water flow autocontrol valve of water-outlet quantity size.
The purpose of this utility model is achieved in that a kind of water flow autocontrol valve by connecting tube, and control valve and tubulose cover cap are formed, and connecting tube is a hollow tube, and its two ends are provided with screw thread, near being the taper tube wall on the inwall of an end; Control valve places in the connecting tube for the hollow-cone body, the two ends of control valve are respectively equipped with bulge loop and lower convex ring, the external diameter of lower convex ring is slightly larger than the external diameter of bulge loop, and extend a central water outlet and a conical surface on the epirelief hoop, this conical surface is corresponding with the taper tube wall of connecting tube, and is provided with a plurality of osculums on control valve; One spring is nested with on control valve, and a tubulose cover cap is connected the bottom of connecting tube.Above-mentioned a plurality of osculum can encircle and be located at control valve body periphery.Above-mentioned a plurality of osculum also can be distributed on the conical surface of control valve.Central water outlet on the above-mentioned control valve can be a plurality of, and the osculum of its body periphery can be single hole relatively.
Advantage of the present utility model: no matter how current or hydraulic pressure change, this water flow autocontrol valve can be with the variation of current or hydraulic pressure, total the water flow of controlling, making the total water current amount is a steady state value, guarantee user's needs, no longer make people feel puzzlement inconvenient and psychology.
Concrete structure of the present utility model further specifies by following examples and accompanying drawing thereof:
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is a cut-away view of the present utility model;
Fig. 3 is a water flow of the present utility model cut-away view hour;
Fig. 4 is the cut-away view of water flow of the present utility model when big;
Fig. 5 is that of the present utility model another implemented illustration;
Fig. 6 is another embodiment's stereogram of control valve;
Referring to Fig. 1-4, the water flow autocontrol valve is made up of connecting tube 1, control valve 2 and tubulose cover cap 3, wherein connecting tube 1 is a hollow tube, two ends are respectively water intake 14 and water outlet 15, the outer wall 13 of connecting tube 1 is provided with the screw thread 17 that is connected with conduit pipe 4 or conversion adapter, and on the inwall of water intake 14 ends, be provided with internal thread 18, be provided with taper tube wall 19 near on the inwall 12 of water outlet 15 1 ends.Control valve 2 places in the connecting tube 1 for the hollow-cone body, the two ends of control valve 2 are respectively equipped with bulge loop 25 and lower convex ring 26, the external diameter of lower convex ring 26 is slightly larger than the external diameter of bulge loop 25, extend upward a central water outlet 22 and a conical surface 24 and go up bulge loop 25, this conical surface 24 is corresponding with the taper tube wall 19 of connecting tube 1, and the intermediate section of control valve 2 is a body 29, is central tube body, and its appropriate position ring is established a plurality of peripheral effluent holes 23 that allow current pass through.
Other has a spring 27 to be nested with on control valve 2, and its internal diameter is slightly larger than the external diameter of bulge loop 25, less than the external diameter of lower convex ring 26.Tubulose cover cap 3 is a hollow circular cylinder, and its outer surface is provided with the screw thread 33 that matches with connecting tube internal thread 18, and its bottom external diameter is the cover cap ring 31 greater than connecting tube water intake 14.During assembling, tubulose cover cap 3 can be placed in control valve 2 between connecting tube water intake 14 and the taper tube wall 19, control valve 2 can not deviate from, and will guarantee the close fit relation between the taper tube wall 19 and the control valve conical surface 24, no matter cooperate all applicable to the utility model with any curved surface.
Referring to Fig. 3, when water flow hour, taper tube wall 19 is separated with the control valve conical surface 24, current will be delivered in the control valve 2 from connecting tube water intake 14, a current part flows out from control valve central authorities water outlet 22, and as moving-wire A, a part is exported from a plurality of peripheral effluents hole 23 around the control valve body 29, as moving-wire B, total water current enters each family through conduit pipe 4 then.
Referring to Fig. 4, when water flow is cumulative, hydro-flow thrust pressure spring 27, and then 19 distances of taper tube wall of control valve 2 and connecting tube 1 are dwindled, though this moment, current also can transport out from peripheral effluent hole 23, but because of water transmission center gradually little, water-outlet quantity also reduces, but central osculum 22, because of the physical property that the increase of hydraulic pressure is quickened current, it is a certain amount of that total water-outlet quantity is also kept, when water flow and hydraulic pressure increase to certain value, the conical surface 24 on the control valve 2 will be fitted on the taper tube wall 19 of connecting tube 1 fully, water can't be flowed out from the osculum 23 of periphery, can only pass through from central water outlet 22, because hydraulic pressure is enough big, flow velocity is enough fast, so total water-outlet quantity or steady state value in the unit time.
For the utility model, the central water outlet 22 on the control valve 2 also can be designed to a plurality of, and the osculum 23 of body periphery also can be designed to single hole relatively, as long as the position of osculum 23 is suitable.
Referring to Fig. 5, conduit pipe 4 screw threads 17 direct and on the connecting tube outer wall of the present utility model link to each other, reach the unimpeded purpose that supplies water, for conduit pipe 4 or the conversion adapter that cooperates different size of all kinds, the screw thread at its connecting tube water outlet 15 places also can design on inwall 12.
Referring to Fig. 6, the peripheral effluent hole 23 on the utility model control valve also can be distributed on the conical surface 24 of control valve.
