The specific embodiment

Embodiment 1

As shown in Figure 1, main body of the present utility model is a water tank 1, and water tank 1 is fixedly mounted on the wall of kitchen or washroom.In the top board perforate of water tank 1, at the one way valve 2 of a float-ball type of top board installed inside, one way valve 2 is to utilize the water level in the water tank 1 just to control keying, realizes water tank and extraneous break-make.Be connected to outlet pipe 5 in the bottom of water tank 1, in the end of outlet pipe 5 water tap be installed, for the usefulness of washing one's hands or washing dish.Reducing valve 3 is installed on the base plate of water tank 1, is communicated with the upper hose 4 of tap water pipe network and the lower port of reducing valve 3 and connects.Constitute these family expenses water saving fixtures thus.

As shown in Figure 2, the concrete structure of the used reducing valve 3 of present embodiment is to be provided with the secondary channels that open on main channel 305 and top, seal the bottom 306 of up/down perforation in valve body 301; In main channel 305, be provided with up big and down small taper type reducing place, be connected with at this reducing place that the bottom is taper type, top is columniform spool 302, on spool 302 tops spring 303 is set, on spring top gland 304 is arranged, there is screw thread the side of gland 304, be threaded with main channel 305, exert pressure so that spool 302 is carried out elasticity.On the interlayer between main channel 305 and the secondary channels 306, have upper port 307 and lower port 308; Upper port 307 is highly relative with spring 303 in the main channel 305, and lower port 308 is positioned at the bottom of secondary channels 306.On the inclined-plane at the reducing place of main channel 305, have skewed slot 309, the lower end of this skewed slot 309 is communicated with main channel 305, the upper end is communicated with lower port 308 and secondary channels 306, thus, between main channel 305 and secondary channels 306, constitute a thread path that is not subjected to spool control, play to water tank 1 continuous, the slowly effect of water filling.

Its working method is: after the utility model is inserted the tap water pipe network, because the pressure of tap water is greater than the pressure of reducing valve 3 medi-springs 303, promote spool 302 and rise, main channel 305 is opened, and tap water enters in the water tank 1 by upper hose 4 and reducing valve 3.When the water level in the water tank 1 surpassed 1/4 height (can set) of water tank, the hydraulic pressure in the water tank 1 adds the elastic force of upper spring 303 will be greater than to pushing away active force on the spool, and spool 302 is depressed, and closes main channel 305.Because spool 302 can not be sealed skewed slot 309, therefore, tap water in the pipe network can also slowly inject water tanks 1 by the skewed slot 309 in the reducing valve 3, lower port 308 and secondary channels 306 at this moment, rise to the top of water tank 1 up to the water surface, by water surface effect, the one way valve 2 at closed tank top, tap water are full of whole water tank 1 at this point.

Water tap on outlet pipe 5 is opened, and the household washes dish with water or when washing one's hands, the liquid level of water tank 1 descends thereupon, one way valve 2 is at once open-minded, water tank 1 top is communicated with atmosphere, and the water in the water tank 1 promptly becomes under normal pressure and flows out, and has realized that thus current are by the slow purpose of outflow of water tap.

If continuously a large amount of waters, then the water surface in the water tank 1 can continue to reduce.When the water surface was reduced to 1/4 water tank height, ductwork pressure can back down the spool 302 in the reducing valve 3, and the main channel 305 of reducing valve 3 is opened, and to water tank 1 quick moisturizing, kept continuous water.

Embodiment 2

The structure of present embodiment is substantially the same manner as Example 1, the structure of the reducing valve 3 and position is set changes to some extent just, and promptly reducing valve 3 is changed to the end face of water tank 1 by the bottom surface of water tank 1, with the upper hose 4 that is arranged in water tank 1 end face join (dotted portion of Fig. 1).

As shown in Figure 3, the concrete structure of the reducing valve 3 in the present embodiment is, in valve body 301, be provided with the secondary channels that seal on main channel 305 and top, open the bottom 306 of up/down perforation, in main channel 305, be provided with up-small and down-big taper type reducing place, be provided with at this reducing place that top is taper type, the bottom is columniform spool 302, in the bottom of spool 302 spring 303 is set, be provided with gland 304 in the spring bottom, there is screw thread the side of gland 304, be threaded with main channel 305, exert pressure so that spool 302 is carried out elasticity.On the interlayer between main channel 305 and the secondary channels 306, have upper port 307 and lower port 308; Lower port 308 is highly relative with spring 303 in the main channel 305, and upper port 307 is positioned at the top of secondary channels 306.On the inclined-plane at the reducing place of main channel 305, have skewed slot 309, the upper end of this skewed slot 309 is communicated with main channel 305, the lower end is communicated with upper port 307 and secondary channels 306, thus, between main channel 305 and secondary channels 306, constitute a thread path that is not subjected to spool control, play to water tank 1 continuous, the slowly effect of water filling.Be fixed with the connecting rod 310 that passes gland in the bottom surface of spool 302, be hung with ball float 311 in the lower end of connecting rod 310.
