Description

Water-saving valve

Affiliated technical field

The utility model relates to a kind of valving of washbasin water system, especially can utilize tap water pressure to adjust the water-saving valve of the water yield automatically.

Background technique

At present, known washbasin water valve, the flow velocity of its water outlet, flow change with the size of pipe water supply pressure, and the user is not suitable for and wastes in a large number the water source very much, if it is more loaded down with trivial details again to adopt the water valve of knob mode to adjust water pressure.

Summary of the invention

In order to overcome the technical deficiency that existing water valve can not be economized on water and the regulating water-quantity operation is loaded down with trivial details, the utility model provides a kind of water-saving valve, this water-saving valve can not only adjust the size of the water yield automatically by hydraulic pressure, reach the water outlet constant flow, thereby realize the purpose of water saving, provide more comfortable using effect to the user.

The technological scheme that its technical problem that solves the utility model adopts is: be provided with valve body, switch knob, stop valve, switch knob and stop valve are hinged, be provided with the vortex chamber in the valve body, its technical characteristics is to be provided with the guiding valve mantle cavity that is connected with the vortex chamber in the valve body, be provided with the slide valve buckle of cylindrical in the guiding valve mantle cavity, have throttle orifice on the barrel of slide valve buckle upper end one side, have the osculum that communicates with the vortex chamber on the barrel of a relative side, the slide valve buckle inner chamber is provided with the throttle valve that is slidingly matched with slide valve buckle inner chamber chamber wall, throttle valve is provided with the metering hole that matches with throttle orifice, is provided with spring between the epicoele wall of throttle valve upper end and guiding valve mantle cavity.Throttle orifice is a triangle, and metering hole is a rectangular, and the throttle valve lower end is fixed with seal ring, and the inner chamber chamber wall of seal ring and slide valve buckle closely is slidingly matched.Have regulator hole on the barrel of slide valve buckle downside, regulator hole is connected with the cavity of stop valve downside.When lifting switch knob and opening stop valve, tap water enters the vortex chamber by pipeline through the throttle orifice on the slide valve buckle and the metering hole on the throttle valve throttling latus rectum that is produced that coincides, behind vortex chamber's current stabilization, flow out from water outlet, in this process, keeping the function of flow of water constant is to be realized by the throttling latus rectum that metering hole on the throttle valve and the throttle orifice lap fit on the slide valve buckle are produced, when tap water pressure is higher than setting pressure, tap water in the pipeline enters the seal ring that the slide valve buckle lower reaction is provided with in the throttle valve bottom surface by regulator hole, because seal ring forms enclosed space at this, throttle valve overcomes spring under effect of water pressure pressure moves in slide valve buckle, regulate the throttling latus rectum, throttling this moment latus rectum diminishes, water-outlet quantity reduces thereupon, when hydraulic pressure and spring pressure reached balance, the throttling latus rectum flow of generation was the setting flow.Like this when pressure of supply water in the pipeline is greater than or less than the pressure of spring, throttle valve just is moved, thereby change the throttling latus rectum of throttle orifice and generation that metering hole overlaps, so just can make water-outlet quantity remain the setting flow, the effect of economizing on water when realizing high pressure, when being lower than setting pressure as pressure of supply water, throttling latus rectum maximum, water nozzle is normal water supply under former pipeline pressure.When the needs big water quantity supplied water, available hand pressed the button and makes the throttling defective valve, realized that former pipeline pressure flow supplies water.

The beneficial effects of the utility model are, adjust the mode of water aperture size in the time of can be by high pressure automatically, reach the water outlet constant flow, thereby realize the purpose of water saving, and are simple in structure.
