Abstract

The utility model relates to a simple water-saving valve which fully uses continuity principle of fluid. The end part of water outlet of a common water valve is matched with a coupling end cover in a bottle cover shape of a baby feeding bottle through threads, the inner bottom part of which is provided with metal circular sheets; the metal circular sheets are provided with minitype small holes (the numbers of the small holes are equal to and more than 1 and equal to and less than 16, the diameter of each hole is equal to and bigger than 0.2 and equal to and smaller than 1). When people open the switches of the water valves, setting numbers of stream current with high speed is sprayed out from the positions of micro holes on the metal circular sheets, and therefore, strong shocking and clear water soil removal can be realized by city water with quite little quantity.

Description

Simple water-saving valve

The utility model relates to a kind of simple water-saving valve that makes full use of the fluid continuity principle.

Under social condition now, the normal domestic water valve only has the effect of water source function, and people can only carry out water and washing mode such as " low speed, low pressure, big flow flushing, rinsing, basin are washed ", but thus, but are water resources profligacy, urban water shortage.

The purpose of this utility model provides a kind of simple water-saving valve, and it is not only simple in structure, special water saving, and can also satisfy people's multiple water easily and wash requirement.

The purpose of this utility model is achieved in that the mode that cooperates by microgroove in the end of common water valve water outlet disposes one " baby bottles bottle cap shape " coupling end cap, and keeps flat a metal garden sheet that is provided with 16 miniature apertures of 1 ∽ (0.2≤φ≤1) in the coupling end cap at the end.Behind the switch of people's one lemon heat water valve, at fluid continuity principle (V ₁S ₁=V ₂S ₂) effect under, tap water will be spouting from the miniature aperture on the sheet of metal garden with very fast speed.Because internal diameter φ 〉=12, the S 〉=113mm of running water pipe and water valve water outlet end ², flow velocity V 〉=2m/s, hydraulic pressure P 〉=1kg/cm ²It is from miniature aperture (1≤n≤16,0.2≤φ≤1) the instantaneous linear velocity V that locates to eject 〉=50m/s, the water demand of the overwhelming majority in the general civilian washing, under the brute force of this high speed jetting stream is impacted, greatly can both be few and need not use under the situation of Cleaning preparations and be met at water.

Since adopt such scheme, water saving not only simple in structure, special, and can also obtain multiple small flow high-speed water jets easily with powerful impact, clear water dirt-removing functions.

The utility model is described in further detail below in conjunction with drawings and Examples.(for the convenience that illustrates, I all only represent common water valve with water tap in accompanying drawing and explanation).

Fig. 1 is a section of structure of the present utility model.

Fig. 2 is the plan view of coupling end cap.

Fig. 3 is the plan view of metal garden sheet.

Among the figure: 1. 3. coupling end caps, 4. metal garden sheets, 5. injection waters 6. of common water valve 2. water valve water outlet ends

Internal diameter 11. Da Yuan holes, O-ring seal 7. miniature aperture 8. switch handle 9. tap water, 10. water valve water outlet end.

In Fig. 1, Fig. 2, coupling end cap (3) shape such as baby bottles bottle cap are provided with a Da Yuan hole (11) being provided with on the inwall of end cap on coupling screw thread, the end face, and big garden bore dia is 12＜d≤13.

In Fig. 1, Fig. 3, metal garden sheet (4) lies at the interior end of coupling end cap (3), and the sheet of metal garden sheet is thick must not be greater than 1mm, and material must satisfy people and carry out the requirement that manual awl is pricked miniature aperture (7) with sharp weapon such as pointed cone, draw point, garden rule temporarily; The center that miniature aperture (7) must be arranged on metal garden sheet (4) is in the track of round spot radius R≤6, and the aperture of miniature aperture (7) with number is set should satisfies following relation.

1) how much the size of aperture φ and hole count n's is inversely proportional to;

2) gross area of miniature aperture should be measured S≤5mm ²

In the embodiment shown in fig. 1, when the metal garden sheet (4) that is provided with little shape aperture (7) is lain in the end in the coupling end cap (3), and press O-ring seal (6) afterwards, outer silk screw thread on coupling end cap and the water valve water outlet end (2) can be screwed and tighten, thereby constitute a complete simple water-saving valve.Behind people's rotating switch handle (8), tap water (9) will water valve water outlet end (2) with and under metal garden sheet (4) go up to form P 〉=1kg/cm ²Hydraulic pressure (in the ordinary course of things, the hydraulic pressure in the city tap-water pipe network is all greater than 1kg/cm ²).Because water valve water outlet end internal diameter (10) is general all greater than 12, i.e. S 〉=113mm ²Flow velocity V 〉=2m/s, and the actual maximum effect area of miniature aperture (7) is definitely less than 4mm ², thereby at fluid continuity principle (V ₁S ₁=V ₂S ₂) effect under, tap water (9) can only gush out from the miniature aperture (7) on the metal garden sheet (4) with speed V 〉=50m/s.When people need the water type, active area of conversion injection water (5) and speed speed, can regulate with rotating switch handle (8) on the one hand, can also screw off coupling end cap (3) on the other hand, the metal garden sheet (4) that takes out of service, changing the metal garden sheet that lastblock is provided with different miniature apertures more in addition regulates, not all right, can also only bore the miniature aperture of bundle temporarily and regulate strictly according to the facts with simple sharp weapon such as general civilian draw point, apicule awl or garden rule awl points.
