Abstract

This invention discloses a water flow limiting chip that can auto adjust water flow. It is composed of the integer of chip connected to adjusting ring. Protuberant location limiting stage is on inner surface of cave bottom surface of the chip, adjusting ring is connected to the stage said. Water flow path is formed by limber holes annular distributed on the chip, the water flow sprayed out as hollow annular water column with very strong impact force to realize metering function and the goal of save water. When water pressure is high, adjusting ring is impacted to open to shelter part water out area of limber hole, the more high of water pressure, the bigger the ring open, the smaller of the water flow path, so the metering function is bigger, and water saving is large. When water pressure is low, the adjusting ring doesn't open, water flow path reaches the largest, so the largest water flow quantity is ensured to cover the shortage of water pressure. Water flow quantity is adjusted by adjust the ring position to reach the goal of saving water and ensuring scrubbing effect, it is fit to be fixed at drainage pipe mouth of water faucet or in flower sprinkle.

Description

Automatically regulate the constrictor of current

Technical field

The present invention relates to a kind of constrictor, particularly a kind ofly be installed in use supporting in water nozzle, the gondola water faucet, and can regulate, limit the flow of current automatically, reach the constrictor of the automatic adjusting current of using water wisely purpose with it.

Background technology

China ground is big, the people is many, water resource is few, and the extremely imbalance that distributes, and a lot of local serious water shortages have lighted red light, and using water wisely has been the task of top priority, is a great and difficult task.

But now a lot of public places, as places such as hospital, school, dining room, station, restaurant, bathrooms, the user is for making things convenient for water, always water tap is opened very big, current are big column and flow out, in fact in so big current, also only have the flowing water about 20% to play cleaning function, and 80% most valuable water resource is poured off, is slatterned in vain.For reaching water-saving purpose, must adopt effective water saving measures, need use the water saving water nozzle instead, gondola water faucet is forced to limit current, but can not be influenced clean result.

Patent No. 03210989.X " ring-type current water-saving valve " just provides a kind of water-saving valve that is installed on the water tap, water is the hollow and annular water column and flows out behind valve, though can reach the remarkable result of water saving 30～60%, but it only has the effect of current limliting also not have the function of regulating current automatically, desirable not enough in the regional result of use that hydraulic pressure is less, there is significant limitation.

Summary of the invention

Technical problem to be solved by this invention is: a kind of constrictor of automatic adjusting current is provided, and its simple in structure, easy making, cost of production are low, with supporting uses such as water nozzle, gondola water faucets, can regulate streamflow automatically, thereby reach both using water wisely, and the good purpose of clean result is economical and practical.

The present invention addresses the above problem the technical scheme that is adopted: regulate the constrictor of current automatically, comprise the chip that has the limbers, the high limiting stand that rises is arranged on the inner surface of the inner chamber bottom surface of described chip, also connect adjustable adjusting ring on the described limiting stand.

Compared with prior art, the invention has the advantages that: this constrictor is made of chip and adjusting ring, and chip is directly by the injection machine injection mo(u)lding, adjusting ring is a rubber seal, it is simple in structure, easily makes, and cost is low, just can assemble without instrument, water stream channel is an annular water flow, ejects from the limbers, has increased hydraulic pressure, have very big impact force, play the water-saving purpose of current limliting.

It also has the function of regulating current automatically in addition, can be according to the height of hydraulic pressure, sealing ring is dashed automatically to rise or does not rise, remedy the influence that hydraulic pressure causes with the size that changes water stream channel, make its size that can limit current reach using water wisely, guarantee that again clean result is good, no limitation is economical and practical, suitable especially in public places, install and use on the water nozzle located such as family or highrise building, gondola water faucet.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Chip 1 is a lamellar body, it in the middle of the lamellar body cavity 2 that has bottom surface 4, uniform ring-shaped distributed 6～12 special-shaped limberss 3 are arranged on the bottom surface, on cavity 2 inwalls on limit, limbers, the rib 7 that corresponding 6～12 circular arcs are arranged has a height to rise in the middle of the inner surface of cavity 2 bottom surfaces and the edge is petal limiting stand 5.

Adjusting ring is rubber seal 6 or elastic ring, nylon ring, and the O-ring seals 6 of circular cross-section slides on the external surface of limiting stand 5 bottoms, and petal edge diameter is greater than limiting stand 5 lower diameter, avoids sealing ring 6 to skid off from limiting stand.

Constrictor is made of the integral body that chip 1 and sealing ring 6 connect into.

This constrictor is installed in the effluent pipe mouth place of water nozzle 8, water outlet trim ring 9 is fixed on the effluent pipe mouth of water nozzle, constrictor is fastened, as shown in Figure 4 with screw thread.

During use, as long as open water nozzle, water just flows out the limbers 3 from constrictor cavity 2 bottom surfaces 4, and the current that jet power is big are for washing, use in the form of a ring.

When if hydraulic pressure is high, water flows through constrictor, current rush at sealing ring 6, make sealing ring spreading outside limiting stand 5, have just blocked the part water-outlet area of limbers 3 outward when sealing ring rises, hydraulic pressure is high more, sealing ring increases and opens more, and limbers 3 water-outlet area are blocked manyly more, and water stream channel is just more little, then metering function is big more, and using water wisely is many more.Do not turn off water nozzle 8 during water, sealing ring 6 sets back under the elastic force effect.

If hydraulic pressure is low, current dash not dynamic seal ring, and then sealing ring can spreading, can not block the limbers, and the water stream channel maximum remedy the deficiency of hydraulic pressure with the water flow maximum, thereby the assurance clean result is good.If there is not adjusting ring, just can not automatically adjust, water stream channel just can not change, and the local clean result that hydraulic pressure is high is good like this, and the low local clean result of hydraulic pressure is just poor, the very big difference of existence has limitation.But this constrictor can be regulated current automatically, and the scope of application is wide, practicality good, can have the place of tap water to use any.
