Abstract

The utility model discloses a water-saving water tap in the valve, which adopts the technical proposal that the water-saving tap comprises a valve body provided with a water outlet opening, a valve core arranged in the valve body and a valve rod extending to the outside of the valve body, and the valve core is installed on the valve rod. The water-saving water tap is characterized in that a normally closed non-return valve is formed between the valve body and the valve core; in particular, the valve rod vertically and downwards extends out the valve body, and the valve core is a solid iron spherical body or a cone-shaped body. The water-saving water tap has the advantages that the water tap can be automatically closed, and the water can be saved, and is the water tap suitable for all public occasions.

Description

Save-water faucet

Technical field

The utility model relates to a kind of valve, particularly the water tap that uses in the life.

Background technique

Present water tap comprises valve body, spool and valve rod, spool is installed on the valve rod, valve rod extends valve body, and during use, rotary valve rod makes valve body unimpeded, current come out from water outlet by valve body, and when finishing using, need once more the counterrotating valve rod that valve body is closed, but after many people have used the water tap of public arena, often forget and close water tap, very waste water resource.

The model utility content

Technical problem to be solved in the utility model provides a kind of save-water faucet that can close automatically after use.

The technological scheme that its technical problem that solves the utility model adopts is: save-water faucet, comprise valve body, be arranged on the spool in the valve body and extend valve rod outside the valve body with water outlet, spool is installed on the valve rod, it is characterized in that, form normally closed one-way valve structures between valve body and the spool;

Concrete, described valve rod extends valve body straight down, and spool is the spheroid or the taper of solid irony;

Further, valve rod be arranged near the water outlet or water outlet straight down, valve rod stretches out along water outlet;

The beneficial effects of the utility model are, utilize normally closed one-way valve, make water tap when finishing using, can stop up valve body automatically owing to hydraulic pressure makes spool, finish and close water tap automatically, and valve rod is more convenient for extending valve body straight down, and spool is solid irony spheroid or taper, then not only can utilize hydraulic pressure to close water tap, can also utilize the gravity of spool that water tap is closed; Again valve rod is arranged near the water outlet or water outlet straight down, valve rod stretches out along water outlet, what the part that contacts with valve rod in the time of can allowing the people use this water tap to wash one's hands was not also stopped is washed by current, relatively health.

Description of drawings

Longitudinal section schematic representation when Fig. 1 closes for embodiment's 1 water tap;

Fig. 2 is the longitudinal section schematic representation of embodiment's 1 water tap when unimpeded;

Longitudinal section schematic representation when Fig. 3 closes for embodiment's 2 water taps;

Fig. 4 is the longitudinal section schematic representation of embodiment's 2 water taps when unimpeded;

Wherein 1 is valve body, and 2 is spool, and 3 is valve rod, and 4 is water outlet.

Embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

The utility model is installed in spool on the valve rod, and spool is arranged in the valve body, and valve rod extends outside the valve body, and valve body and spool are formed the save-water faucet that can close current after normally closed one-way valve utilizes hydraulic pressure formation to use automatically.

Embodiment 1

This example is extended valve body 1 straight down with valve rod 3, and spool 2 is solid irony spheroid, conveniently utilizing spool 2 gravity, and valve rod 3 is arranged near the water outlet 4 longitudinal section schematic representation such as Fig. 1 when it is closed, longitudinal section schematic representation such as Fig. 2 when unimpeded.

When needs used this save-water faucet to wash one's hands, only with hand upwards can drive extended valve rod 3 spool 2 and moves up in the top, and then the one-way valve formed of valve body 1 and spool 2 is opened, and makes valve body 1 unimpeded, and then water flows out from water outlet 4 by valve body 1; When not re-using this save-water faucet, decontrol valve rod 3, then spool 2 is because hydraulic pressure and self gravitation fall naturally, and water tap has just been closed in then valve body 1 sealing.And because valve rod 1 is arranged near the water outlet 4, staff and valve rod 3 must be by certain current flushing, relatively health when then using.

Embodiment 2

Compare this example with embodiment 1 water outlet 4 is set to straight down, valve rod 3 stretches out along water outlet 4, longitudinal section schematic representation such as Fig. 3 when it is closed, longitudinal section schematic representation such as Fig. 4 when unimpeded.

Because valve rod 3 stretches out from water outlet 4, valve rod 3 must be washed by water always when then using, more clean hygiene.

More than the solid irony taper of all replaceable one-tenth of spool 2 in 2 embodiments.

Describe according to appeal, can find out that 2 embodiments can close water tap automatically after use, using water wisely, and because valve rod is all washed by current, health is clean.
