Abstract

The swirl-flow injection washing water-saving device is formed from swirl-nozzle, swirler and multi-stage injector. Said swirler is mounted in ismetric channel after negative throat nozzle so as to produce rotary jet flow. The injector can be connected after swirl-nozzle, and can inject air into the injector, and can mix the air with rotary water flow so as to form air-water two-phase flow to increase volume flow quantity of fluid and form lots of discontinuous dispersion phase, and said above-mentioned air-water two-phase flow can be jetted from water-saving device for washing car body and other equipment to be cleaned, and can attain the goals of saving water and raising washing effect.

Description

Vortex lead jetting type washing water-saving device

Technical field:

Patent of the present invention relates to vortex lead jetting type washing water-saving device, is mainly used in carwash, flushes the toilet, environmental sanitation field such as road, track, bridge, river shoal, seabeach, external wall of house.

Background technology:

Existing sanitaryware flushing or carwash have dual mode, and the one, direct water flushing is washed away sanitary equipment at a high speed with a large amount of water dirt is taken away with water, and this will consume a large amount of water, but also has increased time water treatment amount.Recently employing compressed air also occurred and sprayed into and form biphase gas and liquid flow in the water pipe, its volume flow is higher than the flow of pure water, though can conserve water in order to wash away sanitary equipment, will increase by a cover compression air system simultaneously, and flushing brings extra trouble to sanitary equipment.

Summary of the invention:

For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of spiral-flow type injection washing water-saving device, this water economizer can not only be economized on water, and only depends on the rotating jet of the pressure generation of water channel self, form gas---water two phase flow, realize washing away, the purpose of carwash, scale removal.

The present invention installs a kind of swirl nozzle behind feed water valve with pressure particularly, press water quickens and flows through the cyclone that is fixed on its underpart and become rotating jet at a high speed through swirl nozzle, and enter in the injection rifle that connects mutually with it, perforation injection from atmosphere by injection rifle top is gone into air, and, from the isometrical passage of injection rifle end, eject at the mixed chamber on injection rifle top and mixed gas----the water two phase flow that forms of current.This bundle two phase flow also can quicken in the convergent jet pipe again, enters the secondary injection rifle that joins with it, also has perforation on this injection rifle, and the injection air makes after further increase of void content of two phase flow once more, flows out at a high speed from the outlet of isometrical passage again.So repeat just to have formed the two phase flow of high voidage for several times, have than single current bigger wash away, washing, scale removal effect, and the water yield that consumes is far fewer than pure current.

Description of drawings:

Fig. 1 is the vortex lead jetting type washing water-saving device general assembly drawing.Fig. 2 is swirl nozzle figure.Fig. 3 is an injection rifle structure chart.Fig. 4 is hydrocyclone structure figure.

Wherein: the 1-swirl nozzle; The 2-cyclone; The 3-perforation; 4-injection rifle; 5-mixes the chamber; 6-connects screw thread; The 7-negative throat noz(zle); The isometrical passage of 8-; The 9-stator; The 10-runner.

Valve export on screw thread 6 and the penstocks connects, 6 inside is conical negative throat noz(zle) 7,7 end communicates with cylindrical isometrical passage 8, cyclone 2 is equipped with in the place ahead of 8, for prevent that 2 skid off from 8,2 and 8 is to be interference fits and its end to have slightly and dwindle, and 6,7,8,2 have constituted swirl nozzle 1.Below swirl nozzle 1,4 top is the mixed chamber 5 of the heap of falling garden shape by spiral marking connection for injection rifle 4, and its top has been by having opened several perforations that communicate with atmosphere 3 garden week, and it leans on circumferential weld and mixed chamber UNICOM.The below of mixed chamber is isometrical passage 8.4 the outside is reserved with screw thread, so that connect second level injection rifle again.The injection rifle also can repeatedly be connected in series.

The specific embodiment:

Fig. 1 also is the vortex lead jetting type washing water-saving device figure that is used to wash the lavatory closet.After unlatching is bound up on feed water valve on the cyclone nozzle, press water enters swirl nozzle 1, enter isometrical passage 8 after in negative throat noz(zle) 7, quickening, here flow to the injection rifle and spray to mixed chamber 5 with regard to having formed rotating jet at a high speed by cyclone 2, because high-speed and high curl, caused the vacuum of mixed chamber, air just flows into mixed chamber and mixed with rotary water current through perforation 3, form gas----water two phase flow, because mixed chamber itself also is a negative throat noz(zle), this strand two phase flow flows through within it, is accelerated once more, enters the isometrical passage of injection rifle bottom, and with injection to enter the air of mixed chamber mixed, the void fraction of gas----water two phase flow is further improved, and the isometrical passage from the injection rifle flows out at a high speed at last, rushes at sanitaryware.

Claims

1, a kind of vortex lead jetting type washing water-saving device, it is characterized in that isometrical passage top behind the circular cone negative throat noz(zle) cyclone of packing into has constituted swirl nozzle, thereafter be connected to the injection rifle, injection rifle front end is the mixed chamber of taper shape that has perforation, and its end communicates with isometrical passage; Injection rifle front and back ends respectively with swirl nozzle and second level injection rifle fixed connection.

2, the cyclone in the vortex lead jetting type washing water-saving device as claimed in claim 1 is characterized in that having the threaded column of spiral channel, and this post places close-fitting with it isometrical passage, makes fluid become rotating jet.
