The water-saving tap of water supply installation
Technical field
The utility model relates to a kind of water-saving tap of water supply installation.
Background technology
The patent No. discloses a kind of water saving joint for the Chinese patent of [200620031767.1], and the water saving joint has the circular hole of diameter 2~6mm for the end at the uniform internal diameter joint embeds the round platform that an end is a smooth flat on the smooth flat of round platform; The water inlet of running water valve is tight with the water saving tip side threaded engagement that embeds round platform; Can limit discharge, reach the purpose of water saving.Though this water saving joint is simple in structure, do not have the effect of good water saving, and function of use is single.
Summary of the invention
The purpose of this utility model is to provide a kind of water-saving tap of water supply installation, and not only water-saving result is good for this water saving joint, and diverse in function.
The utility model is achieved through the following technical solutions:
The water-saving tap of the utility model water supply installation, it is characterized in that: comprise the water saving cover that can be connected with the water supply installation outlet pipe, the outer middle side part of described water saving cover is provided with delivery port, be provided with the elasticity dash loose piece that is positioned at the water saving cover body between the delivery port of described delivery port and outlet pipe, described elasticity dash loose piece is descending during the up delivery port of blocking outlet pipe and under water impact greatly under the elastic force effect all the by-pass flow hole when blocking delivery port.
The utility model moves up and down in the water saving cover body by elasticity dash loose piece, thereby can play different regulating actions according to the flow velocity difference of water.At the current that flow out hour, because the effect of elastic force makes elasticity dash loose piece to the motion of delivery port direction, the normal operation of this device does not have tangible pressurized effect; And when current are big, the pressure of current acts directly on the elasticity dash loose piece in this device, makes elasticity dash loose piece to the motion of delivery port place, the delivery port water flow section is amassed reduced, thereby increase the cover body inside water pressure, when water flows out, just improved the flow velocity of water greatly.
This device is economized on water aspect two when big current: on the one hand since the sectional area of delivery port reduced greatly, thereby the flow that makes water has had bigger restriction, when normally being connected to the water tap terminal, maximum amount of water is 30% ~ 40% of an ordinary faucet maximum amount of water, makes the passive water saving of people; On the other hand, because water speed is bigger, spray is splash during use, this will make people feel that psychologically current are very big, will go on one's own initiative current to be turned down to use, and reach the initiatively purpose of water saving.This device can use on water tap or filter outlet pipe, diverse in function, and water-saving result is remarkable.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is an organigram of the present utility model;
Fig. 2 is the B-B sectional view of Fig. 1;
Fig. 3 is the organigram that the utility model is connected with water filter;
Fig. 4 is the organigram that the utility model is connected with water tap;
The specific embodiment
The water-saving tap of the utility model water supply installation, comprise the water saving cover 1 that can be connected with water supply installation outlet pipe 4, water saving cover 1 outer middle side part is provided with delivery port 2, be provided with the elasticity dash loose piece 3 that is positioned at the water saving cover body between the delivery port 7 of delivery port 2 and outlet pipe, elasticity dash loose piece 3 is descending during the up delivery port of blocking outlet pipe and under water impact greatly under the elastic force effect all by-pass flow hole 5 (as shown in Figure 1 and Figure 2) when blocking delivery port.
Above-mentioned water supply installation is a water filter 9, perhaps is water tap 6.
Above-mentioned water saving cover is threaded or socket with the water supply installation outlet pipe.
For the ease of manufacturing, also can be provided with the support cover 8 that is used for support elastic dash loose piece elastic component in the water saving cover body, delivery port 2 is arranged on (as shown in Figure 4) on the support cover 8, and promptly the water saving cover only is to play fixed support cover and the effect that is connected the water supply installation outlet pipe.
The utlity model has simple in structurely, reasonable in design, can on the outlet pipe of water supply installations such as water tap or strainer, use, diverse in function, water-saving result is remarkable.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
