Abstract

The utility model relates to a flow limiting sheet for automatically regulating water flow, which is composed of a whole body connected by a chip and an adjusting ring, wherein the internal surface of the internal chamber bottom surface of the chip is provided with a raised spacing station which is connected with the adjustable adjusting ring. A water flow passage is formed by water through holes which are circularly distributed on the chip, and water flow is ejected in hollow and annular water columns. The utility model which has very strong impact force performs the flow limit action, and the water saving goal is obtained. Simultaneously, when water pressure is high, the adjusting ring is impacted and expanded; the partial water outlet area of water through holes is sheltered; the higher the water pressure is, the larger the adjusting ring expands; the smaller the water flow passage is, the larger the flow limit action is and the more the water is saved. When the water pressure is low, the adjusting ring does not expand; the water flow passage is the largest, and the water outlet flow capacity is ensured to be maximum to make up for the insufficiency of the water pressure. The water flow capacity is automatically adjusted by the positional adjustment of the adjusting ring, and the goal of saving the water and ensuring washing effects is obtained. The utility model is suitable for being installed in a water outlet pipe opening or a spray nozzle of a water faucet and is matched with the water faucet.

Description

Automatically regulate the constrictor of current

Technical field

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

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 in the utility model is: the constrictor that a kind of automatic adjusting current are provided, 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 technical scheme in the invention for solving the above technical problem is: the constrictor of regulating 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, advantage of the present utility model is: 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 embodiment of the present utility model is 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.
