Abstract

The utility model discloses a current-limiting water-saving device used on public occasions, comprising a body and an O-shaped rubber ring, the body is a shape of a disc, the middle of the water contacting surface of which is provided with a hoop cover that is higher than a surface and is concaved to form a convex over-current cap on a water yielding surface, the middle of the over-current cap is provided with a central button used for fixing the O-shaped rubber ring, the surrounding area of the O-shaped rubber ring and the central button is provided with a plurality of water flowing holes, the total area of the water flowing holes determines the unit interval flow rate of tap water, when the hydraulic pressure of tap water is increased, the flowing speed of water is expedited, but the O-shaped rubber ring arranged in the middle is pressed to be deformed, so that part of the area of the water flowing holes can be covered to lead the flowing water current to become thin, so the unit interval total flow rate of tap water is not changed. If the utility model can be arranged in front of the taps on public occasions, the water can be saved even the thin water current is kept lasting.

Description

The current-limiting type water economizer

Technical field

The utility model relates to the water saving fixtures field, specifically refers to a kind of current-limiting type water economizer that is arranged in the water supply pipe.

Background technique

In modern society, along with economic development with to the excessive exploitation of resource, energy shortage, environmental pollution problem are outstanding day by day.Therefore people are to energy-conservation, and water saving is reached common understanding substantially, so there is the people to fall over each other to study various energy-conservation, water saving equipment.Aspect water saving, what generally developing is middle water recycling device, and water-saving toilet water tank and so on is also arranged certainly.It is bigger to develop this series products input, and for the moment can not very fast popularization.In some public arenas, as public's water tap that station, harbour etc. is located, flowing water is opened to such an extent that gurgle with gurgling and to ring, and also nobody is distressed.Though what have is equipped with infrared induction control or foot switch, this class water tap cost height, trouble is installed, fragile, and when opening time-consuming, the effort of current size adjustment.Therefore the applicant assert in the water outlet front of this class water tap a current-limiting apparatus to be set through research in a few years, is a good method that reaches mandatory water saving purpose.

The model utility content

The purpose of this utility model is: for the water tap of public situation provides a kind of front end current-limiting apparatus, make water tap when opening, the flow restriction in the unit time reaches water-saving purpose in a suitable scope.

The technological scheme of the utility model technical solution problem is: rabbeting to go into a current-limiting apparatus in the pipe coupling of water tap front is the current-limiting type water economizer.This current-limiting type water economizer comprises body and rubber o-ring, and described body is in the form of annular discs, in the middle of the plane of its side that meets water, is provided with the ring set of high out-of-plane, and the inside recessed overcurrent cap that forms water one side direction outer lug.In the middle of described overcurrent cap bottom, be provided with the center button that is used for fixing rubber o-ring, around rubber o-ring and center button, be provided with some water passage holes, the water flow of the gross area decision unit time of described water passage hole.

The utility model can keep the constant flow of water outlet constant, its principle is when tap water hydraulic increases, though the speed of current is accelerated, but middle rubber o-ring is crushed and is out of shape, a part of area of the water passage hole around covering, the current of process are attenuated, so the total discharge of water does not still change in the unit time.It is installed in the front end of some public arena water taps, even nobody closes water tap and water tap " is done little by little without a break ", the water of its waste also is limited.

Description of drawings

Fig. 1 is a plan view of the present utility model;

Fig. 2 is a worm's eye view of the present utility model;

Each title and mark among the figure: 1. body, 2. ring set, 3. the overcurrent cap, 4. water passage hole, 5. the center buckle, 6. rubber o-ring.

Embodiment

As depicted in figs. 1 and 2: the current-limiting type water economizer comprises body 1 and rubber o-ring 6, body 1 is in the form of annular discs, in the middle of meeting water a side plane, it is provided with the ring set 2 of high out-of-plane, and the inside recessed overcurrent cap 3 that forms water one side direction outer lug, buckle 5 in described overcurrent cap 3 bottoms around rubber o-ring 6 and center and be provided with some water passage holes 4 on every side, the water flow of the gross area decision unit time of described water passage hole 4, it is installed between the joint of water valve and running water pipe, when water valve was opened, the water flow of the overcurrent cap 3 of process current-limiting type water economizer was subjected to the control of water passage hole 4 gross areas.According to the flow of design in advance, the flow of its water is not subjected to just the influence of the unlatching size of outlet valve and hydraulic pressure and invariable.

Claims

1. current-limiting type water economizer, comprise body and rubber o-ring, it is characterized in that: described body (1) is in the form of annular discs, in the middle of the plane of its side that meets water, be provided with the ring set (2) of high out-of-plane, and the inside recessed overcurrent cap (3) that forms water one side plane to outer lug, in the middle of described overcurrent cap (3) bottom, be provided with the center that is used for fixing rubber o-ring (6) and buckle (5), be provided with some water passage holes (4) on every side around rubber o-ring (6) and center button (5), the water flow of the gross area sum decision unit time of described water passage hole (4).
