Abstract

Opfindelsen vedrører en skybrudsventil der kan kobles til forkortede nedløbsrør. Den simple mekanik vil kunne anvendes til at reducere nedbør i kloakafledningssystemer, når det regner kraftigt. Skybrudsventilen udløses automatisk under ekstremregn, så de store mængder tag-vand ledes til terræn. Skybrudsventilen består af en reducertragt (1), som modtager nedløbsvand. Når det regner nor-malt løber vandet direkte i kloak som det plejer. Når det regner ekstremt stemmes vandet op i reducertragten, som hindrer vandet i at komme til kloak. Reducertragten (1) kan fungere med eller uden en bundprop (7), som lukker mekanismen ved hjælp af et flydelegeme (5), der løftes når vandet stemmes op i tragten. Skybrudventilen har et selvrensende bladfang (4). Skybrudsventilen kan placeres lige over terræn eller højere oppe på nedløbsrøret og monteres forskellige former for aflederemner (9) (16) (20). Skybrudsventilen anvendes hvor det kan accepteres at oversvømme arealer midlertidigt - eksempelvis på græsplæner og andre permable overflader, eller til "skybrudsveje".The invention relates to a cloud burst valve which can be coupled to shortened drainage pipes. The simple mechanics can be used to reduce rainfall in sewer drainage systems when it rains heavily. The cloudburst valve is automatically released during extreme rain, so the large amounts of roof water are directed to the terrain. The burst valve consists of a reducing funnel (1) which receives runoff water. When it rains normally, the water flows directly into the sewer as it usually does. When it rains extremely, the water is tuned into the reducing funnel, which prevents the water from entering the sewer. The reducing funnel (1) can operate with or without a bottom plug (7) which closes the mechanism by means of a floating body (5) which is lifted when the water is tuned into the hopper. The burst valve has a self-cleaning blade catch (4). The cloudburst valve can be placed just above ground or higher on the downpipe and various types of deflector (9) (16) (20) are mounted. The cloudburst valve is used where it is acceptable to temporarily flood areas - for example on lawns and other permeable surfaces, or for "cloudburst roads".

Skybrudsventilen - BeskrivelseCloud Break Valve - Description

Opfindelsen angår en skybrudsventil, der omfatter en reducertragt, hvor reducertragten er en tragtformet regnvandsbegrænser til vand fra nedløbsrør, hvor reducertragten har en skråt afskåret modtagende åbning opad og en indsnævret begrænsende åbning som bundhul nedad, hvor bundhullets størrelse kan reguleres ved justering af reducertragtens længde.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a cloud burst valve comprising a reducing funnel, wherein the reducing funnel is a funnel-shaped rainwater limiter for drainage water, the reducing funnel having an obliquely cut receiving opening upwardly and a narrowed downward opening as a downhole downward, the size of the bottomhole being adjustable by reducing the length of the bottomhole.

Ved meget voldsomme regnskyl kan kloaksystemer ikke rumme det vand, som tilføres via tage og veje, hvilket medfører, at kloakvand stiger op i kældre og på gader eller udledes urenset fra rensningsanlæg.In very heavy rainfall, sewer systems cannot accommodate the water supplied by roofs and roads, which means that sewer water rises in basements and streets or is discharged uncleaned from treatment plants.

Princippet med at lede vand uden om kloaksystemer, når det regner meget, er tidligere patenteret ved anordninger placeret enten på nedløbsrør eller under jorden i kloaksystemet. I det amerikanske patent US 2930392 aktiveres en sliske monteret på nedløbsrøret af nedløbsvand, som fanges af en hylde på slisken, som vipper ned og åbnes og derved leder vand til terræn. Andre patenter US 3026893 og DE 2746585 viser indvendige klapsystemer oppe i røret, der angiveligt aktiveres af store mængder regn. Ligeledes er problemet søgt løst i BA 2013 00046 med en vifteformet bevægelig tragt og klap.The principle of conducting water outside of sewer systems when it is raining is previously patented by devices located either on drainage pipes or underground in the sewer system. US Patent US 2930392 activates a slide mounted on the drainage pipe of runoff water, which is trapped by a shelf on the slide which tilts down and opens, thereby directing water to the terrain. Other patents US 3026893 and DE 2746585 show internal flap systems up in the pipe which are reportedly activated by large amounts of rain. The problem was also solved in BA 2013 00046 with a fan-shaped movable funnel and flap.

Der kendes en tragt uden bevægelige dele, som, i den simple form, afskærer kun en del af ekstremregnvandet til kloak, men nok til at, hvis reducertragten opsættes i tilstrækkeligt stort antal, reducere presset på det fælles kloaksystem i ekstreme nedbørssituationer. Et eksempel er vist i US 5032264There is known a funnel without moving parts which, in its simple form, cuts off only part of the extreme rainwater for sewage, but enough to reduce the pressure on the common sewage system in extreme rainfall situations, if sufficiently reduced. An example is shown in US 5032264

Der, hvor reducertragten monteres, skal kloakken aldrig håndtere mere tagvand end det, der defineres som ’’normalregn”. Ekstreme regnmængder vil automatisk flyde over og blive ledt direkte til terræn.Where the reducer is installed, the sewer should never handle more roof water than what is defined as '' normal rain ''. Extreme rainfalls will automatically flow over and be directed directly to terrain.

Fra tysk patentskrift DE3526936 kendes regnvandsopsamlere, der er monteret umiddelbart nedenfor tagfladen, og hvori der benyttes bevægelige tragte, der er enten lige eller skråt afskåret.German Patent Specification DE3526936 discloses rainwater collectors mounted immediately below the roof surface and using movable hoppers that are either straight or obliquely cut.

Ved opfindelsen tilvejebringes en alternativ skybrudsventil til den indledningsvis nævnte art. Dette opnås ifølge opfindelsen ved en skybrudsventil af den indledningsvis nævnte art, der er kendetegnet ved, at der er anbragt et ophængt flydelegeme inde i reducertragten, som via en snor er forbundet med en prop, der hænger neden for tragtens begrænsende åbning.The invention provides an alternative cloud burst valve of the kind mentioned above. This is achieved according to the invention by a cloud burst valve of the type mentioned initially, characterized in that a suspended float body is arranged inside the reducing funnel, which is connected via a string to a plug which hangs below the restrictive opening of the hopper.

Reducertragten i skybrudsventilen ifølge opfindelsen fungerer ved hjælp af en flydelukker. Flydelukkeren er af en art, der består af et flydelegeme placeret inde i reducertragten. Flydelegemet er via en snor forbundet med en prop, der hænger neden for det reducerende hul. Når vandet under ekstrem regn stemmes op i reducertragten, løftes flydelegemet og proppen, således at proppen lukker det begrænsende hul. I disse situationer løber alt vand ovenud af reducertragten og ud på terræn. Derved skal kloaksystemet under ekstrem regn/skybrud ikke håndtere regn fra nedløb med skybrudsventiler. Når regnen ophører, siver vandet langsomt ud af ventilen, så proppen igen åbner. Under normal regn lukker proppen ikke. Selve flydelegemet er ophængt i reducertragten, så det ikke uforvarende kommer til at lukke nedløbet permanent.The reducing funnel in the cloud burst valve according to the invention operates by means of a float shutter. The float shutter is of a kind consisting of a float body located inside the reducing funnel. The floating body is connected via a string to a plug which hangs below the reducing hole. When the water is heated in the reducing funnel under extreme rain, the float body and the plug are lifted, so that the plug closes the limiting hole. In these situations, all water flows out of the reducer and onto the terrain. In this way, the sewerage system during extreme rainfall / rainfall should not handle rainfall from downfalls with rainfall valves. When the rain stops, the water slowly leaks out of the valve, opening the plug again. During normal rain the plug does not close. The floating body itself is suspended in the reducing funnel so that it does not inadvertently close the drain.

Skybrudsventilen ifølge opfindelsen kan kobles til nedløbsrør for at reducere mængden af nedbør til kloak ved ekstremregn. Skybrudsventilen vil kunne anvendes som et af flere tiltag til at reducere vandmængden i kloakafledningssystemer, når det regner kraftigt. Skybrudsventilen anvendes, hvor det kan accepteres at oversvømme lokale arealer midlertidigt - eksempelvis på græsplæner og på andre permable overflader eller til gader og veje, der er konstrueret som ’’skybrudskanaler”.The cloud burst valve according to the invention can be coupled to downpipes to reduce the amount of rainfall to sewage in extreme rain. The cloudburst valve can be used as one of several measures to reduce the amount of water in sewer drainage systems when it is raining heavily. The cloudburst valve is used where it is acceptable to temporarily flood local areas - for example, on lawns and other permeable surfaces or to streets and roads constructed as '' cloudburst channels ''.

Skybrudsventilen ifølge opfindelsen omfatter en tragtformet regnvandsbegrænser til vand fra nedløbsrør - kaldet ’’reducertragt”. Reducertragten kan placeres mellem et nedløbsrørs udløb og over en nedløbsbrønd på en måde, så reducertragten dels er over og under terræn. Reducertragten placeres med en skråt afskåren åbning opad og en indsnævret reducerende åbning nedad. Før reducertragten monteres, tilpasses nedløbsrøret oven for reducertragten til en passende længde i forhold til tragtens øverste åbning. Reducertragtens bundhul kan reguleres ved justering af tragtens længde. Derved kan reducertragten tilpasses en given tagflades areal i forhold til en ønsket afskæring af regn til kloak. Reducertragtens øvre åbnings laveste punkt placeres væk fra husmur og fundament, så det vand, der opstemmes, fordi det ikke kan passere det reducerende hul, flyder ud på terræn i stedet for i kloak. Reducertragten kan anvendes i flere forskellige sammenhænge og med andre anordninger alt efter givne situationer og ønsker om at styre vandets afledning. I en yderligere udførelsesform omfatter skybrudsventilen et selvrensende bladfang, som er placeret i en skrå vinkel i tragtens øvre del over flydelegemet. Bladfanget ligger umiddelbart til kant i åbningens laveste punkt. Umiddelbart under nedløbsrørets fikseringspunkt i reducertragtens højeste del fastgøres bladfanget. Blade og andet skidt glider af bladfanget, når det regner. I en yderligere udførelsesform af skybrudsventilen er reducertragten indrettet til placering i en krave til placering over en eksisterende nedløbsbrønd. Denne krave holder reducertragten på plads, og den giver overløbsvand en retning væk fra mur og fundament. I denne udførelsesform er det også muligt at placere bladfang. I en yderligere udførelsesform er reducertragten og kraven udført som en samlet enhed. Denne udførelsesform kan også fungere med bladfanget. I en yderligere udførelsesform er reducertragten indrettet til placering længere oppe i nedløbsrøret, evt. over en regntønde. Reducertragten er indrettet til placering inde i nedløbet gennem et udskåret hul. Skybrudsventilen omfatter en afledersliske til placering længere oppe på nedløbsrøret end reducertragten i forbindelse med en åbning. I denne udførelsesform er det også muligt at placere bladfang. I en yderligere udførelsesform, i forbindelse med den højere oppe placerede skybrudsventil, er den snor, der holder flydeventilen oppe, forlænget udenfor røret. Snoren kan trækkes ud og fæstes i et fæste. Derved holdes brundproppen permanent oppe i en lukket position, så alt regn, uanset intensitet, ledes til terræn eller eksempelvis en regntønde. For eksempel er snoren fæstnet til flydelegemet og forløber gennem et øje fra indersiden til ydersiden af reducertragten til fastgørelse på ydersiden af nedløbsrøret. I en yderligere udførelsesform omfatter skybrudsventilen en bevægelig vippeklap for at lede vandet ud af nedløbsrøret. Denne vippeklap er monteret i et udlederhul, som sidder i en vinkel på røret. Vippeklappen er vægtet, så den nedre del er lidt tungere end den øvre, hvilket bevirker, at vippeklappen hviler på udlederhullet, når den ikke er udløst af ekstrem regn. Vippeklappen udløses ved, at opstemmet vand skubber til den nedre del af vippeklappen. Herved tipper vippeklappen og holdes åben af vand, der falder på vippeklappens øvre del, så længe det regner. Via vippeklappen ledes alt vand nu til terræn eller anden konstruktion. Vippeklappens nedre del er som sagt tungere end den øvre, så når det holder op med at regne, falder trykket på den øvre del af klappen og dermed bliver den nedre del igen tungere og klappen vipper automatisk på plads. Når vippeklappen ikke er udløst, løber vandet til kloak. I en yderligere udførelsesform omfatter den ovennævnte skybrudsventil en manuel betjenelig fjederlås til at holde vippeklappen permanent åben.The cloud burst valve according to the invention comprises a funnel-shaped rainwater limiter for drainage water - called '' reducer ''. The reducer can be placed between the outlet of a downpipe and over a downstream well in a way that the reducer is partly above and below ground. The reducing funnel is placed with an obliquely cut opening upwards and a narrowed reducing opening downwards. Before mounting the funnel, the downpipe above the reducer is adjusted to a suitable length relative to the top opening of the hopper. The bottom hole of the reducer can be adjusted by adjusting the length of the hopper. Thereby the reducer can be adapted to the area of a given roof surface in relation to a desired cut of rain to sewer. The lower point of the upper funnel of the reducer is placed away from the house wall and foundation so that the water that is heated because it cannot pass through the reducing hole flows out onto the terrain rather than into the sewer. The reducer can be used in a variety of contexts and with other devices depending on given situations and wishes to control the discharge of water. In a further embodiment, the cloud burst valve comprises a self-cleaning blade catch located at an inclined angle in the upper portion of the hopper above the float body. The leaf catch is immediately on edge at the lowest point of the opening. Immediately below the downpipe fixing point in the highest part of the reducing funnel, the blade cap is attached. Leaves and other debris slip off the leaf trap when it rains. In a further embodiment of the cloud burst valve, the reducing funnel is arranged for placement in a collar for placement over an existing drain well. This collar holds the reducer funnel in place and it gives overflow water a direction away from the wall and foundation. In this embodiment, it is also possible to place leaf catch. In a further embodiment, the reducing funnel and collar are designed as a single unit. This embodiment can also work with the blade catch. In a further embodiment, the reducing funnel is arranged for placement further up in the downpipe, possibly. over a rain barrel. The reducing funnel is arranged for placement inside the drain through a cut hole. The burst valve includes a diverter slip for placement further up on the downpipe than the reducing funnel in connection with an opening. In this embodiment, it is also possible to place leaf catch. In a further embodiment, in conjunction with the higher-up cloudburst valve, the string holding the float valve up is extended outside the tube. The cord can be pulled out and fastened in a bracket. Thereby, the well plug is permanently held in a closed position so that all rain, regardless of intensity, is directed to the terrain or, for example, a barrel. For example, the string is attached to the float body and extends through an eye from the inside to the outside of the reducing funnel for attachment to the outside of the downpipe. In a further embodiment, the cloud burst valve comprises a movable rocker flap to guide the water out of the drain pipe. This rocker flap is mounted in a discharge hole which sits at an angle to the pipe. The rocker flap is weighted so that the lower part is slightly heavier than the upper, which causes the rocker flap to rest on the discharge hole when it is not triggered by extreme rain. The rocker flap is triggered by the stirred water pushing to the lower part of the rocker flap. In this way, the rocker flap tips and is held open by water that falls on the rocker flap as long as it rains. Through the rocker flap, all water is now directed to terrain or other construction. As mentioned, the lower part of the rocker is heavier than the upper, so when it stops raining, the pressure on the upper part of the flap drops and thus the lower part again becomes heavier and the flap automatically tilts in place. When the rocker flap is not released, the water runs to sewer. In a further embodiment, the aforementioned cloud burst valve includes a manually operable spring lock to keep the rocker flap permanently open.

Fig. 10 Viser snit af en modificeret reducertragt i vejbrønd. I fig. 1 og 2 ses et snit gennem skybruds ventilen. Det længde tilpassede nedløbsrør 2 er placeret over skybrudsventilens modtagende åbning 3, som ses over det selvrensende bladfang 4. Når det regner, vil skidt fra tag og tagrende glide af bladfanget 4 og ud på terræn 12. Inde i reducertragten 1 ses et flydelegeme 5 ophængt i et øje 6. Under flydelegemet 5 og nedenfor det justerbare bundhul 8 hænger kegleproppen 7. Bundhullet 8 kan gøres større ved afskæring af tragtens længde, derved opnås en justeringsmulighed i forhold til den ønskede begrænsning af vand til kloak i forhold til en given tagflades areal. Skybrudsventilen er fikseret i en krave 9, som placeres oven på nedløbsbrønden 10. Kraven 9 sikrer, at det strømmende vand ledes væk fra husets fundament, og at der ikke kommer skidt og vand ned i brønden på ydersiden af reducertragten 1. I fig. 1 ses skybruds ventilen under normal regn - her er flydelegemet 5 ikke båret af vand, og dermed lukker kegleproppen 7 ikke for afløb til kloak. I fig. 2 vises skybrudsventilen under ekstremregn. Her er flydelegemet 5 løftet af det opstemmede vand, som ikke kan nå at passere gennem bundhullet 8. Flydelegemet løfter proppen 7 op i bundhullet 8, hvilket lukker af for afledning af vand til kloak. Vandet løber ud over reducertragtens 1 laveste punkt og ud på terræn 12. Når flydelegemet 5 er aktiveret, vil bundhullet 8 være lukket, så længe det regner. Når regnen ophører, vil det opstemmede vand sive ud via en indbygget utæthed i proppen 7, således at proppen 7 igen kan åbne og tillade normalregn uhindret passage til nedløbsbrønd 10.FIG. 10 Displays a section of a modified reducer in the road well. In FIG. 1 and 2, a section through the cloud burst valve is shown. The length-adapted downpipe 2 is located above the receiving opening 3 of the cloudburst valve, which is seen above the self-cleaning leaf catch 4. When it rains, dirt from the roof and gutter slides off the leaf catch 4 and out onto terrain 12. Inside the reducer funnel 1 a floating body 5 is seen suspended. in the eye 6. Below the float body 5 and below the adjustable bottom hole 8 hangs the cone plug 7. The bottom hole 8 can be enlarged by cutting the length of the funnel, thereby providing an adjustment possibility in relation to the desired limitation of water to sewer relative to the area of a given roof surface. . The burst valve is fixed in a collar 9, which is placed on top of the drain well 10. The collar 9 ensures that the flowing water is led away from the housing foundation and that no dirt and water enters the well on the outside of the reducing funnel 1. In fig. 1, the cloudburst valve is seen during normal rain - here the floating body 5 is not carried by water, and thus the cone plug 7 does not close to drains for sewage. In FIG. 2, the cloud break valve is shown during extreme rain. Here, the floating body 5 is lifted by the suspended water, which cannot pass through the bottom hole 8. The floating body lifts the plug 7 up into the bottom hole 8, which closes for drainage of water to the sewer. The water extends beyond the lowest point of the reducing funnel 1 and onto terrain 12. When the floating body 5 is activated, the bottom hole 8 will be closed for as long as it rains. When the rains cease, the suspended water will seep out via a built-in leakage in the plug 7, so that the plug 7 can again open and allow normal rainfall unhindered passage to drain well 10.

Fig. 3 viser opfindelsen udefra. Her ses et tilpasset nedløbsrør 2 placeret over en reducertragt 1 med bladfang 4. Reducertragten 1 er placeret i en krave 9.FIG. 3 shows the invention from the outside. Here is shown a custom downpipe 2 located above a reducing funnel 1 with leaf catch 4. The reducing funnel 1 is located in a collar 9.

Fig. 4, 5 og 6 viser en reducertragt 1 med bladfang 4 som skybrudsventil indbygget i en indsats 2a til nedløbsrør 2. Denne indsats 2a kan placeres i en passende højde i forhold til afledning til eksempelvis en regntønde. Afledning sker automatisk via et hul 17 på siden af indsatsen 2a og ud af en aflederrende 13, når den indvendige konstruktion med flydelegeme 5 og prop 7, som beskrevet i Fig. 1 og 2, er aktiveret ved ekstremregn. Under aflederrenden 13 hænger ophænget til flydelegemet 5, som også manuelt kan trækkes op og fikseres med en hægte 16 i en låsekrog 15.1 Fig. 4 og 5 ses mekanismen under normal regn, hvor vandet løber i kloak. I Fig. 6 ses mekanismen udløst automatisk af ekstremregn eller manuelt åbnet ved træk og fiksering af proppen 7 ved hjælp af hægten 16 og låsekrogen 15.FIG. 4, 5 and 6 show a reducing funnel 1 with leaf catch 4 as a cloud burst valve built into an insert 2a for downpipes 2. This insert 2a can be placed at an appropriate height in relation to, for example, a rain barrel. Drainage automatically takes place via a hole 17 on the side of the insert 2a and out of a diverter ring 13 when the internal structure with floating body 5 and plug 7, as described in FIG. 1 and 2, is activated by extreme rain. Below the diverter gutter 13 hangs the suspension of the floating body 5, which can also be manually pulled up and fixed with a hook 16 in a locking hook 15.1. 4 and 5, the mechanism is seen during normal rainfall where the water flows into sewers. In FIG. 6, the mechanism is triggered automatically by extreme rain or manually opened by pulling and fixing the plug 7 by means of the hook 16 and the locking hook 15.

Fig. 7 viser en reducertragt 1 placeret i en indsats 2b sammen med en vippeklap 20, der er monteret i et udlederhul 19. Vippeklappens 20 lidt tungere nedre del 21 hviler på udlederhullet 19, når det ikke regner eller kun regner normalt.FIG. 7 shows a reducing funnel 1 located in an insert 2b together with a rocker flap 20 mounted in a discharge hole 19. The slightly heavier lower part 21 of the rocker flap 20 rests on the drain hole 19 when it is not raining or only raining normally.

Fig. 8 og 9 viser samme konstruktion som i Fig. 7 men med en udløst vippeklap 20. Figuren viser situationen efter at reducertragtens 1 opstemmede vand har ’’skubbet” vippeklappens nedre del 21 op på sin vej ud af udlederhullet 19. Dette åbnede vippeklappen 20, der nu holdes åben af vand, der falder ned på vippeklappens øvre del 22. I den åbne situation ledes vand ud på terræn eller i anden konstruktion. I Fig. 9 ses vippeklappen manuelt udløst og holdt åben ved hjælp af en fjerderlås 14.FIG. 8 and 9 show the same construction as in FIG. 7 but with a triggered flip-flop 20. The figure shows the situation after the reduced water of the reducing funnel 1 has '' pushed '' the lower part 21 of the flip-flop up its way out of the discharge hole 19. This opened the flip-flop 20, now held open by falling water. on the upper part of the rocker flap 22. In the open situation, water is discharged onto terrain or other construction. In FIG. 9, the rocker flap is manually released and held open by a fourth lock 14.

Fig. 10 viser en modificeret reducertragt 1 placeret i en under risten 17 i en vejbrønd 18. Reducertragten er forsynet med en krave 11, der kan holde den på plads i vejbrønden 18. Under ekstremregn vil overfladevand ligge længere tid på terræn og løbe til kloaksystemet med forsinkelse.FIG. 10 shows a modified reducing funnel 1 located in one under the grate 17 in a road well 18. The reducing funnel is provided with a collar 11 which can hold it in place in the road well 18. Under extreme rain, surface water will lie longer on the ground and run to the sewer system with delay. .
