144710 - 2 - oven nedad lukkende ventiltallerken udsættes let for til-slamning eller -smudsning, og risikoen for, at ventilen ikke kan lukkes fuldstændig, er derfor stor. Endvidere er aggregatet sammensat af flere kostbare enkeltdele, hvorfor fremstillingsprisen er forholdsvis høj.144710 - 2 - the valve plate closing downwards is easily exposed to sludge or soiling and the risk that the valve cannot be completely closed is therefore high. Furthermore, the unit is composed of several costly individual parts, which is why the manufacturing price is relatively high.
Der kendes også et ventilaggregat, hvor en fra oven nedad lukkende ventil samvirker med en kontraklap, der er svingbart lejret i afløbskanalen. Denne konstruktion gør det vanskeligt at renholde især afløbskanalen, da kontraventilklap-pen er fast monteret i denne og derfor hindrer fri adgang til kanalen, selv om ventilaggregatet i øvrigt fjernes.A valve assembly is also known, in which a downwardly closing valve cooperates with a contract flap which is pivotally mounted in the drain channel. This construction makes it difficult to clean especially the drainage duct, since the non-return valve flap is firmly mounted in it and therefore prevents free access to the duct, although the valve assembly is otherwise removed.
Fra beskrivelsen til dansk patent nr. 64.265 kendes et ventilaggregat af den omhandlede art, som er sammenbygget af et stort antal massive enkeltdele og trykkes ved hjælp af spændeorganer mod brøndvæggen med afløbsåbningen. Dette aggregat er meget kompliceret opbygget og frembyder kroge og under skæringer, hvori partikler i spildevandet kan sætte sig fast og hindre den ønskede funktion. En bøsningspakning, der sikrer ventiltallerkenens aktiveringsmekanisme, er ikke kun dyr og pladskrævende, men vil også have en tendens til at blive hård og utæt, da ventilen sjældent aktiveres. Der er behov for regelmæssige eftersyn og justeringer.From the specification of Danish Patent No. 64,265, a valve assembly of the kind in question is known, which is assembled by a large number of solid individual parts and is pressed by means of clamping means against the well wall with the drain opening. This unit is very complicated in structure and provides hooks and during cuts in which particles in the wastewater can get stuck and hinder the desired function. A bushing gasket that secures the valve plate activation mechanism is not only expensive and space consuming, but will also tend to become hard and leaky as the valve is rarely activated. Regular inspections and adjustments are needed.
På lignende måde er den overdelen mod rørbøjningen sikrende skrue ufordelagtig, fordi spildevandets aggressivitet vil medføre, at den sætter sig fast og vanskeliggør udtagning for rengøring. Fastholdelse af ventilaggregatet ved hjælp af den viste spændemekanisme giver ingen tilfredsstillende tætning mellem brøndens indre og afløbsroret, og den mod brøndvæggen stående punktbelastning er uhensigtsmæssig og kun tilladelig, såfremt brønden er fremstillet af støbejern eller et lignende stift materiale. I en brønd af eksempelvis plastmateriale er det kendte aggregat uanvendeligt.Similarly, the top of the pipe bend securing screw is disadvantageous because the aggressiveness of the wastewater will cause it to become stuck and make it difficult to remove for cleaning. Retaining the valve assembly by means of the clamping mechanism shown does not provide a satisfactory seal between the interior of the well and the drain pipe, and the point load against the well wall is inappropriate and permissible only if the well is made of cast iron or a similar rigid material. In a well of, for example, plastic material, the known assembly is useless.
Endelig har ventiltallerkenen en fremspringende næse, der glider frem og tilbage mellem to føringsribber i rørbøjningen. Den mellemliggende føringsrende vil især i sin neder-ste del let blive tilsmudset, således at en sikker lukning af ventilen ikke kan opnås, da ventiltallerkenen derved vil lukke skævt, altså uden fuldstændigt lukkende anlæg.Finally, the valve plate has a protruding nose that slides back and forth between two guide ribs in the tube bend. In particular, the intermediate guide ring will be easily soiled in its lower part, so that a secure closure of the valve cannot be achieved, as the valve plate will thereby close warped, ie without completely closing the system.
“ 3 - 144710"3 - 144710
Formålet med den foreliggende opfindelse er at anvise et ventilaggregat af den omhandlede art med en håndbetjent afsparringsventil og en selvvirkende kontraklap, der enkelt og billigt og alligevel på tilfredsstillende måde lader sig montere tæt i en brønd. Endvidere skal den anviste konstruktion have ringe byggehøjde og glatte passager, således at en sikker og vedvarende funktionsduelighed er opnået. Endelig skal aggregatet omfatte en vandlås.The object of the present invention is to provide a valve assembly of the present type with a hand operated shut-off valve and a self-acting contract flap which can be easily and inexpensively and yet satisfactorily mounted tightly in a well. Furthermore, the design in question must have low build height and smooth passageways, so that a safe and lasting functionality is achieved. Finally, the unit should include a water trap.
Dette opnås ved den i krav 1 anviste konstruktion.This is achieved by the construction of claim 1.
Ved denne konstruktion er der glatte gennemgange for spildevandet, og aggregatet lader sig let montere tæt mod brøndvæggen med afløbsåbningen. Også tætningen af den ventiltallerkenen aktiverende spindel er yderst simpel og med ringe byggehøjde.In this construction, there are smooth passages for the waste water, and the unit can easily be mounted close to the well wall with the drain opening. Also, the seal of the valve plate activating spindle is extremely simple and of low build height.
Det anviste aggregat består af kun få enkeltdele og kan let demonteres, hvorved også kontraklappen fjernes fra afløbskanalen, således at denne er frit tilgængelig for rengøring. Den nedefra opad mod ventilsædet bevægelige ventiltal-lerken frembyder den fordel, at ventilen er selvrensende, således at forstyrrelse på grund af tilslutning eller -smudsning i det væsentlige er undgået. Det er også en væsentlig fordel, at alle enkeltdele kan fremstilles af formstof, og at ventilspindelen beskyttet er indført i spindelmøtrikken nedefra, således at risiko for korrosion er elimineret.The specified assembly consists of only a few parts and can be easily dismantled, thereby also removing the contract flap from the drain channel, so that it is freely accessible for cleaning. The valve plate movable from the bottom upwards towards the valve seat offers the advantage that the valve is self-cleaning, so that interference due to connection or soiling is substantially avoided. It is also a significant advantage that all individual parts can be made of plastic material and that the valve spindle is protected from the bottom of the spindle nut so that the risk of corrosion is eliminated.
Ved uagtsom drejning af det spindelaktiverende håndhjul er der risiko for, at ventilspindelen drejes ud af indgreb med møtrikken. Dette medfører, at ventiltallerkenen falder ned på bunden af afløbsbrønden eller -beholderen, hvorefter ventilen ikke kan genlukkes. Denne risiko kan ifølge opfindelsen elimineres, ved at aggregatet udformes som anvist i krav 2 eller 4.Negligible rotation of the spindle-actuating handwheel may cause the valve spindle to rotate out of engagement with the nut. This causes the valve plate to fall to the bottom of the drain well or container, after which the valve cannot be closed. This risk can be eliminated according to the invention by designing the assembly as claimed in claims 2 or 4.
Det er ifølge opfindelsen fordelagtigt, at ventilaggregatet udformes som anvist i krav 5· Ved denne konstruktion opnås en sikker styring af ventiltallerkenen under dennes bevægelse, og det kan ikke forekomme, at spindelen arbejder skævt i møtrikken, hvilket kunne vanskeliggøre eller hindre betowning af ventilen. Ventilføringen medfører også, at ventiltallerkenen trykkes ensartet mod ventilsædet.According to the invention, it is advantageous for the valve assembly to be designed as claimed in claim 5. In this construction, a safe control of the valve plate is obtained during its movement, and the spindle does not appear to be distorted in the nut, which could hinder or prevent the valve from being pressurized. The valve guide also causes the valve plate to be pressed uniformly against the valve seat.

Til opnåelse af en upåklagelig tætning, som eksempelvis ved oversvømmelser skal kunne modstå væsentlige kontratryk i længere tid, er det ifølge opfindelsen fordelagtigt, at ventilaggregatet udformes som angivet i krav 6. Den formsluttende pakningsring er i sin ringnot udmærket sikret mod fjernelse.In order to obtain an impeccable seal which, for example, in the event of floods, can withstand significant counter pressure for a long period of time, it is advantageous according to the invention that the valve assembly is designed as stated in claim 6. The form-fitting packing ring is in its ring groove excellent secured against removal.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser en del af en afløbsbrønd med et ventilaggregat ifølge opfindelsen, delvis gennemskåret, og fig. 2 et snit vinkelret på snitfladen i fig. 1.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 is a partial sectional view of a drainage well with a valve assembly according to the invention; and FIG. 2 is a section perpendicular to the sectional surface of FIG. First
På tegningen er vist en del af en afløbsbrønd 10, hvortil der er adgang gennem et aftageligt dæksel 11, og fra hvis side en skråt nedadgående afløbskanal 12 udgår. Under afløbskanalens 12 munding findes i brønden 10 en lomme 13, hvor et ventilaggregat 15 kan ophænges og fastgøres ved hjælp af skruer 16. Ventilaggregatet 15 omfatter en 90° rørbøjning 17 med afløbsrør 18 og indløbsrør 19· I oversiden af afløbsroret 18 findes en boring 20, hvori en spindelmøtrik 21 med håndhjul 25 er lejret tætnende mod rørvæggen. Spindelmøtrikken 21 strækker sig koaksialt med indløbsrørets 19 længdeakse ind i rørbøjningen 17. I møtrikkens 21 nedre del er iskruet en ventilspindel 22, hvis nederste ende bærer en ventiltallerken 23. Over ventiltallerkenen 23 findes i indløbsrøret et ventilsæde 24, mod og fra hvilket ventiltallerkenen kan bevæges ved drejning af håndhjulet 25. Langs kanten har ventiltallerkenen en omløbende ringnot 26, i hvilken en gummipakningsring 27 med rektangulært tværsnit er monteret. Fra ventiltallerkenen 23 strækker sig aksialt et afstandsrør 28 ned mod bunden af brønden 10 til begrænsning af ventiltallerkenens 23 bevægelse. Afløbsrorets 18 munding 30 er omgivet af en flange 31, der er i ét med rørbøjningen. Forneden går flangen 31 over i en indføringsnæse 14, der ligger i et tangentialplan til indløbsrøret 19. Denne indføringsnæse 14 optages i lommen 13, når ventilaggregatet 15 montere« i brønden 10. Ved hjælp af en pakningsring 32 er brøndens 10 indre tætnet mod afløbskanalen 12.The drawing shows a portion of a drain well 10 to which is accessed through a removable cover 11, and from which a sloping downward drain channel 12 is ejected. Under the mouth of the drainage channel 12, in the well 10 is a pocket 13 where a valve assembly 15 can be suspended and secured by screws 16. The valve assembly 15 comprises a 90 ° pipe bend 17 with drainage pipe 18 and inlet pipe 19. In the upper side of the drainage pipe 18 there is a bore 20 , in which a spindle nut 21 with handwheel 25 is sealed tightly against the pipe wall. The spindle nut 21 extends coaxially with the longitudinal axis of the inlet pipe 19 into the tube bend 17. In the lower part of the nut 21 is a valve spindle 22, the lower end of which carries a valve plate 23. Above the valve plate 23 is a valve seat 24, against and from which the valve plate can move. by turning the handwheel 25. Along the edge, the valve plate has a circumferential ring groove 26, in which is mounted a rubber gasket ring 27 of rectangular cross section. From the valve plate 23, a spacer 28 extends axially down to the bottom of the well 10 to limit the movement of the valve plate 23. The mouth 30 of the drain pipe 18 is surrounded by a flange 31 integral with the pipe bend. Below, the flange 31 enters an insertion nose 14, which lies in a tangential plane to the inlet pipe 19. This insertion nose 14 is received in the pocket 13 when the valve assembly 15 is mounted «in the well 10. By means of a packing ring 32, the interior of the well 10 is sealed to the drain channel 12. .

Ved kanten over mundingen 30 på afløbsroret 18 er 1 flangen 31 udformet et hængselleje 33 for en kontraklap 34, der kan bringes til tætnende at dække rørmundingen 30. Klappens 34 kantområde er tilbagebøjet til opnåelse af et sikkert tætnende anlæg ved rørmundingen 30.At the edge over the orifice 30 of the drain pipe 18, the flange 31 is provided with a hinge bearing 33 for a counter flap 34 which can be sealed to cover the pipe mouth 30. The edge area of the flap 34 is bent to provide a secure sealing system at the pipe mouth 30.
Af fig. 2 fremgår det, hvorledes indløbsrørets 19 inderside bærer langsgående føringsribber 35, som griber ind i udskæringer eller næser 36 langs ventiltallerkenens 23 periferi og sikrer, at ventiltallerkenen ikke kan drejes. Afstandsrøret 28 kan naturligvis erstattes af anslag på ribberne 35 eller i indløbsrøret. Det er også tænkeligt, at der aellem spindelen 22 og møtrikken 21 indbygges et ventilbevægelsen begrænsende anslag.In FIG. 2 shows how the inside of the inlet pipe 19 carries longitudinal guide ribs 35 which engage cutouts or noses 36 along the periphery of the valve plate 23 and ensure that the valve plate cannot be rotated. The spacer 28 may, of course, be replaced by abutments on the ribs 35 or in the inlet tube. It is also conceivable that between the spindle 22 and the nut 21 a valve movement limiting stop is incorporated.
Det viste ventilaggregat virker på følgende måde. I normalstilling er ventiltallerkenen 23 ved hjælp af håndhjulet 25 ført så langt fra ventilsædet, som afstandsrøret 28 eller andre anslagsorganer tillader. Der er herved uhindret adgang fra brønden 10 til afløbskanalen 12, fordi gennem-strømmende vand på grund af sit tryk kan åbne klappen 34.The valve assembly shown works as follows. In normal position, the valve plate 23 is guided by the handwheel 25 as far from the valve seat as the spacer 28 or other abutment means allow. Thereby, there is unobstructed access from the well 10 to the drain channel 12, because flowing water can open the flap 34 due to its pressure.
Ved tilbagestrømning fra afløbskanalen 12 lukkes klappen 34, således at vand ikke kan strømme fra kanalen 12 ind i brønden 10.Upon backflow from the drain channel 12, the flap 34 is closed so that water cannot flow from the channel 12 into the well 10.
Ved vedvarende risiko for tilbagestrømning, eksempelvis ved oversvømmelse i afløbssystemet, løftes dækslet 11, og ventiltallerkenen løftes ved hjælp af det derved tilgængelige håndhjul op mod ventilsædet 24.In case of a persistent risk of backflow, for example by flooding in the drainage system, the cover 11 is lifted and the valve plate is lifted up by means of the hand wheel thus accessible against the valve seat 24.
Ved at løsne skruerne 16 kan man frigøre ventilaggregatet 15 og løfte det op fra brønden 10. Herved bliver også afløbskanalen 12 frit tilgængelig for rengøring.By loosening the screws 16, the valve assembly 15 can be released and lifted from the well 10. This also allows the drain channel 12 to be freely accessible for cleaning.
I normalstillingen, dvs. med åben ventil 23,24, tjener det viste ventilaggregat 15 også som vandlås, forudsat at væskeniveauet i brønden 10 når op om indløbsrøret 19.In the normal position, ie. with open valve 23,24, the valve assembly 15 shown also serves as a water lock, provided that the liquid level in the well 10 reaches the inlet pipe 19.
Alle dele af ventilaggregatet kan fremstilles af formstof, der er korrosionsbestandigt og frembyder lille vedhæft-ningstilbøjelighed. Ved sprøjtestøbning eller dybstrækning af formstof opnås endvidere stor fremstillingsnøjagtighed, således at fremstillingsspildprocenten bliver ringe.All parts of the valve assembly can be made of resin which is corrosion resistant and exhibits little adhesion resistance. Furthermore, by injection molding or deep stretching of plastic, great manufacturing accuracy is obtained, so that the production waste percentage becomes low.
