Description

Water jet

Technical field

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

Background technology

By US-PS 4,852,801 known a kind of water jets, this water jet have nozzle-like delivery port and can be by the water inlet of check-valves sealing, tank is supplied with by cistern by this water inlet.In order to launch very brief, very high fountain, water receiver also has the compressed air supply port.When the compressed air of impulse form was carried through this supply port, the water that is arranged in tank was fountain shape ground and penetrates from delivery port.When compressed air delivery was interrupted once more, the tank pressure inside descended, and the check-valves of sealing water inlet opens and tank is filled water again.The profile of the current that eject deposits the only influence of the unlatching duration of air entrainment valve by compression at such cloth.

Summary of the invention

Therefore, task of the present invention is, finishes a kind of water jet, and this water jet has been realized the more changeability of architectural fountain.

In addition, in known water jet before, the valve that check-valves is constituted as on water inlet simply, can arranges with moving pivotally.Because strong pressure oscillation, the material of valve has born 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 feature of claim 1, and relate at this point check-valves just the check-valves of the feature by having claim 8 solved.But have at least two energy by the opening of valves of independent operation and the compressed air supply port of closing by tank according to the present invention, then can influence the speed and the height of the current that eject.When only opening a valve and only supplying with compressed air by an opening, the speed of the current that the velocity ratio of the current that eject ejects when particularly opening a plurality of valve simultaneously is low.In addition, the shape of water spray can be subjected to the opening time of valve and be subjected to acting on air pressure influence on the valve.

In the another kind of scheme of water jet, the delivery port of nozzle-like is not directly to be arranged near the water surface, but be installed on the delivery port and attach troops to a unit in the lower area termination in the pond of each water jet.At first to cause water flow jet to get very high for Shuo Ming structure, and the structure of mentioning has later formed the effect of a kind of " extreme misery mountain " seemingly outburst.

When use for example following claim 8 and after during illustrated check-valves, normal 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 being connected of flexible membrane seal.The percolation element has can be by the opening of percolation and the structure that plays the maintenance effect of type body of formation percolation element that is the form of framework.Membrane seal designs as follows, that is, this membrane seal abuts on the percolation element also with all openings sealings from compression-side when pressurization.Membrane seal preferably is permanently connected with the percolation element, and this for example can realize that with pressure casting method this must be a rigidity because of the percolation element basically under the situation by the use different materials, and membrane seal must be flexible.But in particularly preferred embodiments, membrane seal is arranged and is enough inherently stables in shape at it, thereby the opening in the percolation element just can seal when only having tangible pressure differential between the outside and inboard.Such foundation check-valves of the present invention just allows percolation fully having only under the very little pressure differential, and seals under unexpected and very big pressure differential.

The specific embodiment

Water jet shown in Figure 1 is made up of the tank 1 with bottom side flange 2, and water jet can for example be fixed on the bottom of fountain equipment by this flange 2.Water jet has delivery port 3 at upside, and has a plurality of water inlets 4 in described embodiment in the bottom side.Water inlet 4 has check-valves 12.At upper area, two compressed air supply ports 5 feed in the tank 1.Be connected with the air conveyor structure of not drawing in detail on the compressed air supply port 5.

Fig. 2 illustrates the water jet from Fig. 1 that is installed in fountain or the man-made lake, and fountain or man-made lake are represented cistern 6 simultaneously, supplies with water jet by cistern 6.At this, delivery port 3 is disposed on the water surface 7, thereby the current that eject that will produce can spray in the clear.It also is feasible that yet delivery port 3 is in the layout of the water surface 7 belows a little, and can very seriously not change effect.

When as shown in Figure 3, on tank 1, installing tank 8, will form a kind of diverse water spray effect.In this arrangement form, delivery port 3 obviously is positioned at the water surface of tank 8 below 7.When current during from delivery port 3 ejection, current are not from tank 8 vertical lifting and rise to very high height, but from tank 8 water wherein are attracted on the very wide face.This has caused the water spray of boiling shape, and the outburst of " extreme misery mountain " sample ground is the same seemingly.

Fig. 4 and Fig. 5 with section illustrate from above accompanying drawing, have a water jet of functions.At this, filled arrows 9 is represented current, and only represents air to flow with the arrow shown in the gabarit 10.In Fig. 4, compressed air 10 enters tank 1 through compressed air supply port 5.Compressed air 10 is arranged in the water 9 of tank 1 with impulse form pushing downwards, and water 9 enters ejectisome 11 in a tubular form there and passes that ejectisome 11 upwards flows and from delivery port 3 ejections again.At this, the ejectisome 11 of tubulose is tapered multistagely and constructs in the mode that is shaped to nozzle at upper area, and this helps forming point and sprays water fast.By the pressure pulse of conveying compressed air 10, the check-valves 12 on the water inlet 4 cuts out and is installed in the check-valves 13 of upside and cuts out, thereby passes through the water 9 and delivery port 3 dissipations of ejection from the pressure uniqueness ground of tank 1.Further describe the function of check-

valves

12 and 13 below by means of Fig. 7 and 8.

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

Fig. 6 is a principle schematic, should described function be described once more by Fig. 6.Be positioned at the water surface following container 1 by water inlet 4 water-fillings.The water-filling of container 1 can also be accelerated, and method is: pump 15 pumps into water in the container 1 through water inlet 4.At this, preferably also be connected with unshowned compensation vessel, so that avoid the compression shock in the pump.Container 1 be in water or cistern 6 in arrange, needn't have water pump 15 like that as described.Yet, rely on this water pump 15 also can finish whole system and be positioned at cistern 6 layout outward.

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

In case one or more valves 17 are opened, compressed air promptly flows in the container 1.At this, check-

valves

12 and 13 prevents that the sky G﹠W from coming out in container 1.By very fast leaked-in air, water is outwards pushed the jet hole that passes on the delivery port 3 at a gallop.Therefore, formed the effect of water cannon.Valve 17 can preferably be sealed in moment once more, thereby can independently or with pump support the ground water-filling once more by the water inlet 4 of container 1.This is that the top check-valves 13 opened equally once more is responsible for allowing air pass through annulus 14 overflowing once more.

Fig. 7 and Fig. 8 illustrate check-valves 12 with details.This check-valves 12 has percolation element 20, and percolation element 20 has opening 21 and bar 22,23.The periphery of percolation element 20 has the FX 24 of constructing ringwise in described embodiment.Percolation element 20 with its FX 24 has pre-determined the stable structure and the shape of check-valves, and is rigidity basically therefore.Compression-side D at percolation element 20 is fixed with membrane seal 25, and this membrane seal 25 is flexibility and resilient with percolation element 20 on the contrary.But membrane seal 25 has certain inherent stability, and the pressure differential between less and compression-side D and the outside A is a level as described in Fig. 8 a basically hour thereby membrane seal 25 is at flow velocity.This has realized that as same water 9 percolations pass through check-valves 12 can seeing among Fig. 8 a, but also as can be seen as among Fig. 5, the outflow of air 10.

Yet, the pressure on acting on compression-side D obviously when acting on the pressure of the outside on the A, membrane seal 25 as be close on the percolation element 20 as described in Fig. 8 b and therefore seal as described in the opening 21 of percolation element 20, thereby do not reflux.For clearly explanation, membrane seal 25 is described in the mode of dissecing in Fig. 8 b.

When percolation element 20 was basket shape structure as described, check-valves 13 was stable especially.Check-valves 13 preferably has many horizontal stays 23 and vertical stay 22, and wherein, vertically stay 22 remotely extends from the center diametrically, and laterally stay 23 extends around the center concentrically.When the percolation element from its FX 24 or from stationary plane or outside A during to compression-side D projection, 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.

The check-valves 13 of water jet upside is not shown specifically.Yet check-valves 13 is basically corresponding to the embodiment of the check-valves among Fig. 7 and Fig. 8 12.Check-valves 13 only medially has recess, and the ejectisome 11 that is used to form water spray extends through this recess.Thus, placed in the middle fixing of membrane seal 25 also can be understood that fixing around the center, just fixing around ejectisome 11.

Same self-evident is not only to be suitable for water according to device of the present invention and check-valves, but also to be provided for other liquid.In this case, " water " speech can be substituted by " liquid ".

Realized different very flexibly water moulding according to water jet of the present invention.Utilize its special check-

valves

12,13, water jet can move and seldom need to safeguard reliably.Yet check-

valves

12,13 also is suitable for other the application target except the water jet of having described.
