Description

Water jet

Technical field

The present invention relates to a kind of water jet according to claim 1 preamble and a kind of be preferably applied on such water jet, according to the check-valves of claim 8.

Background technology

By US-PS4,852,801 known a kind of water jets, the delivery port that this water jet has nozzle-like and the water inlet can closed by check-valves, tank is supplied by cistern by this water inlet.In order to launch very brief, very high fountain, water receiver also has compressed air supply port.When the compressed air of impulse form is through the conveying of this supply port, the water being arranged in tank be fountain shape penetrate from delivery port.When compressed air delivery is interrupted again, the pressure drop of tank inside, the check-valves of closed water inlet opens and tank fills water again.The profile of the current ejected can the impact of the only unlatching duration of air entrainment valve by compression under such layout.

Summary of the invention

Therefore, task of the present invention is, completes a kind of water jet, and this water jet achieves the more changeability of architectural fountain.

In addition, the valve that in known water jet before, check-valves is configured to simply on water inlet, can arrange with moving pivotally.Due to strong pressure oscillation, the material of valve bears extreme load, to such an extent as to it is very high to be subject to abrasiveness.To this, the present invention also seeks new solution.

The present invention based on task and problem solved by a kind of water jet with the feature of claim 1, and relate to check-valves at this point and just solved by the check-valves of the feature with claim 8.By tank according to the present invention have at least two energy by can independent operation valve open and close compressed air supply port, then can affect the current ejected speed and height.When only opening a valve and only by an opening supply compressed air, the speed of the current ejected when the velocity ratio of the current ejected particularly opens multiple valve is simultaneously low.In addition, the air pressure impacts that opening time and being subject to that the shape of water spray can be subject to valve acts on valve.

In the another kind of scheme of water jet, the delivery port of nozzle-like is not directly be arranged near the water surface, but is being arranged on lower area termination that is on delivery port and that attach troops to a unit in the pond of each water jet.First it is very high that the structure illustrated causes water flow jet to obtain, and the structure mentioned below defines one " extreme misery mountain " effect of breaking out seemingly.

Below use such as when claim 8 and check-valves illustrated afterwards, often need maintainability, service life and the precise function of water jet can be improved widely.The special feature of such check-valves is to form the percolation element of structure and the connection of flexible membrane seal.Percolation element has can by the structure playing maintenance effect of type body of the formation percolation element of the opening of percolation and the form in framework.Membrane seal designs as follows, that is, this membrane seal to abut from compression-side when pressurizeing percolation element and sealed by all openings.Membrane seal is preferably permanently connected with percolation element, and this such as can realize with pressure casting method by using when different materials, this is because percolation element must be rigidity substantially, and membrane seal must be flexible.But in particularly preferred embodiments, membrane seal is arranged at it and is enough inherently stables in shape, thus just can close when the opening in percolation element only exists obvious pressure differential between outside and inner side.Like this just allow percolation completely according to check-valves of the present invention only having under very little pressure differential, and to close under unexpected and very large pressure differential.

Detailed description of the invention

Water jet shown in Figure 1 is made up of the tank 1 with bottom side flange 2, and water jet such as can be fixed on the bottom of fountain equipment by this flange 2.Water jet has delivery port 3 in upside, and has multiple water inlet 4 in bottom side in described embodiment.Water inlet 4 has check-valves 12.At upper area, two compressed air supply ports 5 pass in tank 1.Compressed air supply port 5 is connected with the air conveyor structure do not drawn in detail.

Fig. 2 illustrates the water jet from Fig. 1 be installed in fountain or man-made lake, and fountain or man-made lake represent cistern 6 simultaneously, supplies water jet by cistern 6.At this, delivery port 3 is disposed on the water surface 7, thus the current ejected that will produce can spray in the clear.But delivery port 3 layout be in a little below the water surface 7 is also feasible, and very seriously can not change effect.

When installing tank 8 as shown in Figure 3 on tank 1, a kind of diverse water spray effect will be formed.In this arrangement form, delivery port 3 is obviously positioned at the water surface less than 7 of tank 8.When current spray from delivery port 3, current are not vertically rise from tank 8 and rise to very high height, but are attracted to by water wherein from tank 8 on a very wide face.Which results in the water spray of boiling shape, the outburst of " extreme misery mountain " sample ground is the same seemingly.

Fig. 4 and Fig. 5 with section illustrate from above accompanying drawing, the water jet with functions.At this, filled arrows 9 represents current, and only represents air flowing with the arrow 10 shown in gabarit.In the diagram, compressed air 10 enters tank 1 through compressed air supply port 5.Compressed air 10 pushes the water 9 being arranged in tank 1 downwards with impulse form, and water 9 enters ejectisome 11 in a tubular form there and upwards flows through ejectisome 11 again and spray from delivery port 3.At this, the ejectisome 11 of tubulose is tapered multistagely and constructs in the mode being shaped to nozzle at upper area, and this is conducive to forming point and spraying water fast.Pass through the pressure pulse of carried compressed air 10, the check-valves 12 on water inlet 4 close and be arranged on upside check-valves 13 close, thus from tank 1 pressure uniquely by ejection water 9 and delivery port 3 dissipation.The function of check-valves 12 and 13 is further described below by means of Fig. 7 and 8.

Fig. 5 illustrates the situation when the compressed air supply on compressed air supply port 5 is closed again.So the hydraulic pressure acted on around tank 1 is greater than the pressure of internal tank.Therefore, the check-valves 12 on water inlet 4 is opened again, and water 9 flows into container 1 inside by water inlet 4.At this, the air in container 1 can by the check-valves 13 at this moment opened and through annulus 14 dissipation around delivery port 3.

Fig. 6 is principle schematic, by Fig. 6, described function should be described again.Be positioned at the container 1 of below the water surface by water inlet 4 water-filling.The water-filling of container 1 can also be accelerated, and method is: water pumps in container 1 through water inlet 4 by pump 15.At this, be preferably also connected with unshowned compensation vessel, to avoid the compression shock in pump.In container 1 is in water or arranges in cistern 6, water pump 15 need not be there is as described.But, also can complete whole system by means of this water pump 15 and be positioned at layout outside cistern 6.

In order to produce water spray, tank 1 is by can the valve 17 of independent operation be connected with the air vessel 16 be under pressure.In order to realize accurately and fast controlling especially, these valves 17 are preferably magnetic valve.Valve 17 also can be connected with compressed air container in the mode of separating, and thus, can be supplied the air of different pressures by compressed air supply port 5.Thus, can also more to be sprayed water effect.

Once one or more valve 17 is opened, compressed air promptly flows in container 1.At this, check-valves 12 and 13 to prevent in air and water from container 1 out.By very fast leaked-in air, water is outwards extruded through at a gallop the jet hole on delivery port 3.Therefore, the effect of water cannon is defined.Valve 17 can preferably be closed again within moment, thus again independently or with pump can support ground water-filling by the water inlet 4 of container 1.This is that the top check-valves 13 equally again opened is responsible for allowing air again be overflowed by annulus 14.

Fig. 7 and Fig. 8 illustrates check-valves 12 with details.This check-valves 12 has percolation element 20, and percolation element 20 is with opening 21 and bar 22,23.The periphery of percolation element 20 has the FX 24 constructed ringwise in described embodiment.The percolation element 20 with its FX 24 is previously determined stable structure and the shape of check-valves, and is therefore rigidity substantially.Be fixed with membrane seal 25 at the compression-side D of percolation element 20, this membrane seal 25 and percolation element 20 are flexible and resilient on the contrary.But membrane seal 25 has certain inherent stability, thus membrane seal 25 is less at flow velocity and pressure differential between compression-side D and outside A is less time, be level substantially as described in Fig. 8 a.This achieve as same can see in Fig. 8 a, water 9 percolation by check-valves 12, but also can be found out as in Figure 5, the outflow of air 10.

But when acting on the pressure on compression-side D and being obviously greater than the pressure acted on the A of outside, membrane seal 25 to be close on percolation element 20 and the opening 21 of therefore percolation element 20 as described in sealing as described in figure 8b, thus does not reflux.In order to clearly illustrate, membrane seal 25 describes in the mode of cutting in figure 8b.

When percolation element 20 constructs in basket shape as described, check-valves 13 is stable especially.Check-valves 13 preferably has many horizontal stays 23 and longitudinal stay 22, and wherein, longitudinal stay 22 remotely extends from center diametrically, and horizontal stay 23 extends around center concentrically.When percolation element from its FX 24 or from stationary plane or outside A raised to compression-side D time, the stability of check-valves and very good by the sealing of diaphragm 25.Percolation element 20 can be preferably the shape of spherical crown or truncated cone shape.

Check-valves 13 on the upside of water jet is not shown specifically.But check-valves 13 is substantially corresponding to the embodiment of the check-valves 12 in Fig. 7 and Fig. 8.Check-valves 13 only medially has recess, and the ejectisome 11 for the formation of water spray extends through this recess.Thus, placed in the middle the fixing of membrane seal 25 also can be understood to fixing around center, fixing namely around ejectisome 11.

Equally self-evidently, be not only suitable for water according to device of the present invention and check-valves, but also be provided for other liquid.In this case, " water " one word can by " liquid " substitute.

Water moulding different very is flexibly achieved according to water jet of the present invention.The check-valves 12,13 utilizing it special, water jet reliably can run and seldom need to safeguard.But check-valves 12,13 is also suitable for other the application target except the water jet described.
