Abstract
The utility model relates to a tap water saving pipe fitting, in particular to an external pressurizing water saving device which comprises a water inlet joint, a water and air mixing pipe and a water outlet joint, wherein the water inlet joint is provided with a tapered water inlet and a tapered water outlet; the reducing water outlet is inserted into an air pressure cavity of the water and air mixing pipe; an air inlet A is arranged on the outer wall of the air pressure cavity. The external pressurizing water saving device is characterized in that certain interval is reserved between the tapered water and air mixing pipe and the water outlet joint; an air inlet B is arranged in the pipe wall of the water outlet joint and positioned at the interval between the water outlet joint and the water and air mixing pipe; and a tapered sealing sleeve is arranged on the inner wall of the air pressure cavity and positioned at the air inlet A. When in water introduction, the mixing cavity can realize water and air mixing, so that the water outlet quantity of the water outlet can be reduced so as to achieve the water saving aim; and after the water is disconnected, the returned water can be prevented from seeping from the air inlet, so that the leakage-proof role can be played.
Description
Technical field
The utility model is a kind of water saving pipe fitting, specifically is a kind of external Boosted water-saving device.
Background technology
Our live and work be unable to do without water, but in use also has phenomenons such as water resource waste and pipe leakage.By in hydraulic pipeline, adding gas, make gas-vapor mix can dwindle the current diameter of delivery port, thereby reduce water supply volume, can make the aqueous vapor mixed flow reach the state of injection at output by the diameter that changes pipeline simultaneously.For example the patent No. is ZL02222972.8 disclosed a kind of " an injection type ejector ".This patent provides a kind of pressure that relies on flow channel for liquids self, forms gas-liquid two-phase flow by injection gas, and reaches the purpose of the speedup consumption reduction of liquid injecting type.But this technology still exists deficiency and defective, mainly is: when closing water, because inertia, the water of anti-stream can be flowed out by air inlet, if things go on like this, causes pipe leakage, brings great inconvenience to use; Isometrical passage is adopted in these technology many places, is unfavorable for that the acceleration of water is flowed, and developing result is poor, causes water-saving result undesirable.
Summary of the invention
The utility model is to overcome the deficiencies in the prior art, only depends on the pressure of current self and does trickle change to installing inside and provide a kind of, thereby reach the water saving and the purpose of leakproof.
The technical scheme that adopts is so for achieving the above object, promptly a kind of external Boosted water-saving device.Comprise water supply connector, gas-vapor mix pipe and water out adapter, wherein water supply connector has tapering type water inlet and undergauge delivery port, and described undergauge delivery port inserts the atmospheric pressure cavity in the gas-vapor mix pipe, has air inlet A at the atmospheric pressure cavity outer wall; It is characterized in that: described tapering type gas-vapor mix pipe and water out adapter are possessed certain interval, and the gap location that is positioned on the water out adapter tube wall with the gas-vapor mix pipe has air inlet B, and are positioned at air inlet A place at described atmospheric pressure cavity inwall and are provided with tapering type sealing shroud.
In the said structure device, gas enters and is full of the gap of gas-vapor mix pipe and water out adapter from air inlet B, enter atmospheric pressure cavity in the gas-vapor mix pipe by air inlet A, evenly mix in hybrid chamber with the current of the atmospheric pressure cavity of flowing through, form air-water mixture, thereby reduce water flow, play the effect of water saving; After disconnecting current, the water that refluxes because of inertia is back to the gas-vapor mix pipe, is subjected to the barrier effect of the sealing shroud of air pressure cavity wall, can not outwards be overflowed by pore, thereby reach the purpose of leakproof.This shows that the effect that the utility model produces owing to said structure is conspicuous.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Among the figure: the 1-water inlet; 2-undergauge delivery port; 3-air inlet B; The 4-atmospheric pressure cavity; The 5-hybrid chamber; 6-air inlet A; The 7-water out adapter; 8-screw thread A; 9-screw thread B; The 10-water supply connector; 11-gas-vapor mix pipe; The 12-groove; The 13-sealing shroud; The 14-centring ring; The 15-sealing ring.
The specific embodiment
Structure of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides, referring to accompanying drawing, external Boosted water-saving device among the figure comprises water supply connector 10, gas-vapor mix pipe 11 and water out adapter 7, wherein water supply connector 10 has tapering type water inlet 1 and undergauge delivery port 2, the atmospheric pressure cavity 4 that described undergauge delivery port 2 inserts in the gas-vapor mix pipe 11 has air inlet A6 at atmospheric pressure cavity 4 outer walls; It is characterized in that: described tapering type gas-vapor mix pipe 11 is possessed certain interval with water out adapter 7, the gap location that is positioned on water out adapter 7 tube walls with gas-vapor mix pipe 11 has air inlet B3, and is positioned at air inlet A6 place at described atmospheric pressure cavity 4 inwalls and is provided with tapering type sealing shroud 13; The outer wall of gas-vapor mix pipe 11 lower ends be equipped with and water out adapter 7 between the sealing ring 15 of sealing; Junction at water supply connector 10 and gas-vapor mix pipe 11 is equipped with centring ring 14; Outer wall in described water supply connector 10 has the groove 12 that cooperates with the O RunddichtringO; Has the screw thread A8 that is connected with the valve delivery port on the outer wall of described water out adapter 7 upper ends; Has the screw thread B9 that is connected with outlet conduit on the outer wall of described water out adapter 7 lower ends.
During installation, the groove 12 and the waterpipe jointing of water supply connector 10 outer walls are tightly connected, and the screw thread A8 of gas-vapor mix pipe 11 upper ends is connected with the valve delivery port is airtight, and the screw thread B9 of lower end is connected with the water outlet waterpipe jointing is airtight.
During work, after water enters from water inlet, by undergauge delivery port 2, hydraulic pressure makes current quicken, and move to the delivery port direction fast, because siphonic effect, and the air that drives in the atmospheric pressure cavity 4 flows to equidirectional, at this moment, form negative pressure in the atmospheric pressure cavity 4, and then atmospheric air enters and be full of the gap of gas-vapor mix pipe 11 and water out adapter 7 by air inlet B3, enter atmospheric pressure cavity 4 by air inlet A6 again, air in the atmospheric pressure cavity 4 and hybrid chamber 5, evenly mix and form the aqueous vapor two phase flow from the water that undergauge delivery port 2 flows out at a high speed, and reach the effect of pressurized water-saving; After stopping to supply water, the water that refluxes because of inertia is back in the gas-vapor mix pipe 11, the barrier effect of the sealing shroud 13 in managed, and current can not outwards overflow from air inlet A6, thereby reach the purpose of leakproof.
