The beneficial effects of the utility model: water-saving valve of the present utility model is resisted against plug by stage clip the inner side surface of baffle ring, thereby block water intake, in the situation that feed-water end hydraulic pressure is very little or not water inlet, can avoids outlet terminal the people to occur and be the water phenomenon steathily of dripping; In addition, in cavity of the present utility model, spool is installed, spool is formed with the osculum that keeps spool both sides cavity to communicate corresponding to the position of guide rod, and osculum is stepped, its large end is towards positioning body one side, under the effect of external force, guide rod can extend in osculum, like this, when the hydraulic pressure of water intake larger, the degree of depth that the end of guide rod extend in osculum is darker, and the area that goes out water space between guide rod and osculum is less, and the water amount of the water-saving valve of flowing through is just less; Otherwise, when the hydraulic pressure of water intake more hour, the degree of depth that the end of guide rod extend in osculum is more shallow, the area that goes out water space between guide rod and osculum is larger, the water amount of water-saving valve of flowing through is just larger, realizes automatically regulating water amount according to hydraulic pressure, to reach the purpose of water saving.
Description of drawings
Fig. 1 is the structural representation (analysing and observe) of non-return water-saving valve of the present utility model;
Fig. 2 is the structural representation (overlooking direction) of spool of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further set forth, wherein, direction of the present utility model is take Fig. 1 as standard.
as depicted in figs. 1 and 2, non-return water-saving valve of the present utility model comprises valve body 1, positioning body 2, baffle ring 3, plug 4, elastic force apparatus 5 and sealing gasket 6, the two ends of valve body 1 are respectively arranged with water intake 11(upper end) and water outlet 12, the centre of valve body 1 is formed with the cavity 13 that keeps water intake 11 to communicate with water outlet 12, positioning body 2 is arranged on the cavity 13 interior (stage casing) of valve body 1, being formed with at least one on positioning body 2 keeps the water port 21(Vertical direction that positioning body 2 both sides cavitys communicate to connect), baffle ring 3 is arranged on water intake 11 1 ends of valve body 1, the inner side surface that is specially the cavity 13 of valve body 1 extends to form above-mentioned baffle ring 3 along circumferential center, plug 4 is arranged in cavity 13 between positioning body 2 and baffle ring 3, plug 4 can slide (up and down) along cavity 13, elastic force apparatus 5 is arranged in cavity 13 between positioning body 2 and plug 4, sealing gasket 6 covers the position that plug 4 contacts with baffle ring 3, elastic force apparatus 5 forces plug 4 against living baffle ring 3 internal surfaces, and seal up simultaneously water intake 11.Like this, in the situation that feed-water end (water intake 11 1 sides) hydraulic pressure is very little or not water inlet, can avoids outlet terminal the people to occur and be the water phenomenon steathily of dripping.
Further, in order to guarantee the directivity of plug 4 motions, avoid occurring between the water port of plug 4 and baffle ring 3 dislocation, the utility model arranges a guide rod 41 that vertically arranges in the lower end of plug 4, corresponding to the position of guide rod 41, a pilot hole 22 that is mated action is set at positioning body 2.
Further, in cavity 13 of the present utility model, spool 7 is installed also, spool 7 is positioned at a side (lower end) of the close water outlet 12 of positioning body 2, spool 7 is formed with corresponding to the position of guide rod 41 osculum 71 that keeps spool 7 both sides cavitys to communicate, osculum 71 is stepped, its large end is towards positioning body 2 one sides, and under the effect of external force, guide rod 41 can extend in osculum 71.Like this, when the hydraulic pressure of water intake 11 is larger, the degree of depth that the end of guide rod 41 extend in osculum 71 is darker, and the area that goes out water space between guide rod 41 and osculum 71 sidewalls is less, and the water amount of the water-saving valve of flowing through is just less; Otherwise, when the hydraulic pressure of water intake 11 more hour, the degree of depth that the end of guide rod 41 extend in osculum 71 is more shallow, the area that goes out water space between guide rod 41 and osculum 71 sidewalls is larger, the water amount of water-saving valve of flowing through is just larger, realization is regulated water amount automatically according to hydraulic pressure, to reach the purpose of water saving.
In order to prevent that guide rod 41 from blocking osculum 71, an end of the close guide rod 41 of osculum 71 is provided with restraining groove, when guide rod 41 arrives the deep-seated of osculum 71 and puts, times so is formed with the water space that of side direction between the sidewall of guide rod 41 and osculum 71.
Wherein, elastic force apparatus 5 is for being squeezed in the stage clip between plug 4 and positioning body 2, and the small end of osculum 71 is cylindrical body, and its large end is the groove that is arranged on the small end both sides, the internal surface of described groove is smooth inclined-plane (part of spheroid), can reduce like this high-velocity fluid and produce noise.
