GULVAFLØBFLOOR DRAIN
Den foreliggende opfindelse vedrører et gulvafløb, som er sluttet til et vakuumsystem for at suge indholdet ud af gulvafløbet, hvor vakuumsystemet hele tiden er i 5 drift for at udføre nævnte udsugning, og hvor gulvafløbet har en ventilindretning, der omfatter dels et ventilsæde, som er monteret ved gulvafløbets udløb, hvilket ventilsæde forbinder gulvafløbet med vakuumsystemet, og dels et ventillegeme, der er bevægbart anbragt i gulvafløbet, idet ventillegemet samvirker med ventilsædet og lukker udløbet, når gulvafløbet er tomt, samt påvirkes på en sådan 10 måde af væske, som løber ned i gulvafløbet, at udløbet åbnes ved at ventillegemet flyttes i forhold til ventilsædet, gennem hvilket undertrykket i vakuumsystemet kan suge væsken ud af gulvafløbet.The present invention relates to a floor drain connected to a vacuum system for sucking the contents out of the floor drain, the vacuum system being constantly in operation to perform said suction, and wherein the floor drain has a valve device comprising partly a valve seat which is a mounted at the outlet of the floor drain, which valve seat connects the floor drain with the vacuum system, and partly a valve body which is movably arranged in the floor drain, the valve body cooperating with the valve seat and closing the outlet when the floor drain is empty, and is affected in such a manner by liquid running. down into the floor drain, that the outlet is opened by moving the valve body relative to the valve seat, through which the vacuum in the vacuum system can suck the liquid out of the floor drain.
Gulvafløb, som er sluttet til et vakuumsystem, findes for eksempel i jernbane-15 vogne og ombord på skibe og fartøjer, men også andre anvendelser er mulige.Floor drains connected to a vacuum system can be found, for example, in railway carriages and on board ships and vessels, but other applications are also possible.
Formålet med vakuumsystemet er blandt andet at suge indholdet ud af for eksempel toiletter eller vandet fra brusekabiner og lignende for videretransport til opsamling i en beholder. Undertrykket i vakuumsystemer er relativt kraftigt, hvorfor det af flere grunde er belejligt at kunne afbryde gulvafløbets forbindelse med 20 vakuumsystemet, når gulvafløbet er tomt. Lukkeindretninger af flere forskellige typer benyttes til dette formål; ligeledes automatiske ventilindretninger, der styres af vand, som løber ned i gulvafløbet.The purpose of the vacuum system is, among other things, to suck the contents out of, for example, toilets or the water from shower cubicles and the like for further transport for collection in a container. The vacuum in vacuum systems is relatively strong, which is why it is convenient for several reasons to be able to disconnect the floor drain connection with the vacuum system when the floor drain is empty. Closing devices of several different types are used for this purpose; likewise, automatic valve devices, controlled by water, which run into the floor drain.
I US 3397710 vises og beskrives yderligere et afløb omfattende et cirkulært skål-25 formet ventilhus, der er lukket ved hjælp af et aftageligt dæksel med huller, og på hvis underside er anlagt flanger. På siden af ventilhuset er anlagt en åbning, hvortil er tilsluttet et tilledningsrør for væsken, og centralt i ventilhusets bund er anlagt en åbning, hvortil er tilsluttet et fraledningsrør, hvor en del af fralednings-røret rager op i selve ventilhuset og er udformet til at fungere som et ventilsæde.US 3397710 further discloses and discloses a drain comprising a circular bowl-shaped valve housing closed by means of a removable cover with holes and on whose underside flanges are provided. On the side of the valve body is provided an opening to which is connected a fluid conduit, and centrally in the bottom of the valve body is provided an opening, to which is connected a discharge conduit, where a portion of the discharge tube protrudes into the valve body itself and is designed to act as a valve seat.
30 2 DK 174868 B1 I den øverste del af ventilhuset er anbragt en elastisk kappe i form af en buet cirkulær plade med en afrundet periferikant, og hvor der centralt i pladen og orienterende mod ventilhusets bund udgår en stift med en passage, og til hvis ende er anlagt en cirkulær metalplade med en periferisk udformet rende. Grundet den 5 buede udformning af pladen vil det område af pladen, hvorfra stiften udgår, ligge an mod de flanger på dækslet, der befinder sig ovenfor området. ' m I den nedre del af ventilhuset er anbragt et cirkulært pladeformet ventillegeme i form af en membran, hvis periferi er formet efter renden på metalpladen, hvor-10 ved, når ventillegemets periferikant placeres i renden, tilvejebringes en lufttæt forbindelse. På den øvre side af ventillegemet er anbragt en belastning i form af en cirkulær plade med en centralt placeret knop med en endeflange. Ventillegemet bliver således presset mod undersiden af den cirkulære plade. I det tilfælde, hvor der ikke er væske i afløbet, vil belastningen fra den cirkulære plade forårsa-15 ge, at ventillegemet hviler imod ventilsædet, hvorved åbningen på fraledningsrø-ret vil være lukket. Herved forhindres effektivt, at eksempelvis gasser fra kloakvandet i fraledningsrøret flyder ud gennem systemet.30 2 DK 174868 B1 An elastic sheath is arranged in the upper part of the valve body in the form of a curved circular plate with a rounded peripheral edge, and a pin with a passageway extending centrally in the plate and facing the bottom of the valve body is arranged a circular metal plate with a circumferentially formed gutter. Due to the curved configuration of the plate, the area of the plate from which the pin exits will abut the flanges of the cover located above the area. In the lower part of the valve body is arranged a circular plate-shaped valve body in the form of a membrane, the periphery of which is formed after the gutter on the metal plate, whereby, when the peripheral edge of the valve body is placed in the gutter, an airtight connection is provided. On the upper side of the valve body is placed a load in the form of a circular plate with a centrally located knob with an end flange. The valve body is thus pressed against the underside of the circular plate. In the case where there is no liquid in the drain, the load from the circular plate will cause the valve body to rest against the valve seat, thereby closing the opening on the discharge pipe. This effectively prevents, for example, gases from the sewer water in the discharge pipe from flowing through the system.
Afløbet fungerer således, at når der løber væske gennem hullerne på dækslet, vil 20 væskeniveauet stige jævnt under ventillegemet, og som følge deraf vil trykket på ventillegemet forøges. Såfremt dette tryk overstiger en forudbestemt værdi, vil ventillegemet blive løftet fra ventilsædet, og væsken kan strømme gennem fraledningsrøret. Ventillegemet er således ikke excentrisk og bevægbart i forhold til ventilsædet.The drain works so that as fluid flows through the holes on the cover, the liquid level will rise evenly below the valve body, and as a result, the pressure on the valve body will increase. If this pressure exceeds a predetermined value, the valve body will be lifted from the valve seat and the liquid may flow through the discharge pipe. Thus, the valve body is not eccentric and movable relative to the valve seat.
25 I tilfælde af en tilstrækkeligt høj indstrømning af væske vil væskeniveauet stige til et sådant niveau, at hele ventillegemet vil blive løftet, indtil knoppen støder mod stiften og lukker passagen i denne. Hvis indstrømningen overstiger det samtidige udløb gennem fraledningsrøret, vil den yderligere stigning af væskeniveauet for-30 anledige, at den luft, der er fanget under pladen på kappen, bliver komprimeret og vil foranledige, at kappen løftes, således at hele kappens overflade vil ligge 3 DK 174868 B1 an mod flangerne på undersiden af dækslet og dække for hullerne, hvorved indstrømningen af væske afbrydes. Det er således kappen, der lukker indløbet ved for stor vandtilstrømning gennem kappen og ikke selve ventillegemet.In the case of a sufficiently high inflow of fluid, the fluid level will rise to such a level that the entire valve body will be lifted until the knob abuts the pin and closes the passage therein. If the inflow exceeds the simultaneous outlet through the outlet pipe, the further rise of the fluid level will cause the air trapped under the plate of the sheath to be compressed and cause the sheath to be lifted so that the entire sheath surface will lie 3 DK 174868 B1 abut the flanges on the underside of the cover and cover for the holes, thereby interrupting the flow of liquid. It is thus the sheath that closes the inlet by excessive flow of water through the sheath and not the valve body itself.
5 Afløbet vil fungere på samme måde som beskrevet ovenfor i det tilfælde, hvor r væsken i stedet ledes gennem tilledningsrøret, dog med den forskel, at trykket på ventillegemets underside etableres hurtigere, således at kappen også hurtigere dækker for hullerne i dækslet. Det er således ikke muligt at lede væske gennem hullerne i dækslet, samtidig med at der ledes væske gennem tilledningsrø-10 ret. Yderligere kan afløbet ikke anvendes i situationer, hvor afløbsrørsystemet er holdt under vakuum.The drain will operate in the same way as described above in the case where the liquid is instead passed through the supply pipe, with the difference that the pressure on the underside of the valve body is established more quickly, so that the cover also covers the holes in the cover more quickly. Thus, it is not possible to pass liquid through the holes in the cover, while at the same time passing liquid through the supply tube. Further, the drain cannot be used in situations where the drain pipe system is kept under vacuum.
I SE, B, 398 654 vises og beskrives følgelig et gulvafløb af den i indledningen angivne art. Med henblik på at opnå sikker, automatisk åbning og lukning af ven-15 tilindretningen i gulvafløbet er ventilsædets tætningsplan stillet skråt i forhold til vandoverfladen i ventilhuset (gulvafløbet), hvorved det mod ventilsædet anliggende ventillegeme, når vandoverfladen stiger i ventilhuset, frigøres fra ventilsædet gennem en brække- eller rullebevægelse, Den nødvendige kraft til at fjerne ventillegemet bliver hermed væsentligt mindre, end hvis ventillegemet måtte 20 tjernes vinkelret mod vandoverfladen.Accordingly, SE, B, 398 654 discloses and describes a floor drain of the kind specified in the preamble. In order to achieve safe, automatic opening and closing of the valve device in the floor drain, the valve seat sealing plane is inclined with respect to the water surface of the valve housing (the floor drain), whereby the valve body adjacent to the valve seat rises as the water surface rises in the valve housing through a breaking or rolling movement. The force required to remove the valve body is thereby considerably less than if the valve body had to be served perpendicular to the water surface.
Formålet med den foreliggende opfindelse er også at tilvejebringe et gulvafløb, hvori forbindelsen med vakuumsystemet åbnes og lukkes automatisk på en simpel måde, og gulvafløbet ifølge opfindelsen udnytter i hovedsagen også et bræk-25 keprincip for fjernelse af ventillegemet fra ventilsædet, men den konstruktive udførelse hertil er væsentligt anderledes.The object of the present invention is also to provide a floor drain in which the connection to the vacuum system is opened and closed automatically in a simple manner, and the floor drain according to the invention also utilizes in principle a fragile principle for removing the valve body from the valve seat, but the construction thereof is significantly different.
Således karakteriseres gulvafløbet ifølge den foreliggende opfindelse ved, at ventilsædet indtager en vandret stilling i det i indledningen definerede gulvafløb, 30 at ventillegemet er udformet som en plade med en i forhold til ventilsædet excentrisk anbragt del, der flyttes på en sådan måde, når den påvirkes af væske, at 4 DK 174868 B1 den mod kraften fra undertrykket i vakuumsystemet, som medvirker til at holde udløbet lukket, vrider ventillegemet bort fra dets tætnende anlæg mod ventilsædet, og at mindst to afstandsorganer er anbragt i gulvafløbet mod hvilke ud over ventilsædet ventillegemet hviler når gulvafløbet er tomt.Thus, the floor drain according to the present invention is characterized in that the valve seat occupies a horizontal position in the floor drain defined in the preamble, that the valve body is formed as a plate with a member eccentrically disposed relative to the valve seat, which is moved in such a manner when it is affected. of liquid, that it opposes the force of the vacuum in the vacuum system which helps to keep the outlet closed, the valve body is pivoted away from its sealing abutment towards the valve seat, and that at least two spacers are placed in the floor drain against which beyond the valve seat the valve body rests. when the floor drain is empty.

Ifølge opfindelsen opnås herved hurtigt og på en meget simpel måde nødvendig ' kraft til at overvinde undertrykket i vakuumsystemet, så ventilindretningen automatisk åbner for udsugning af væske ud af gulvafløbet. Desuden er det ved hjælp af denne udførelse lettere at tilpasse gulvafløbet til nutidens krav om lav 10 byggehøjde med bevarelse af stor evne til gennemstrømning af væske.According to the invention, force is thereby obtained quickly and in a very simple manner to overcome the vacuum in the vacuum system, so that the valve device automatically opens for the suction of liquid out of the floor drain. In addition, this design makes it easier to adapt the floor drain to today's low 10 building height requirements with high fluid retention capability.
Ventilsædets horisontale arrangement i gulvafløbet medfører nemlig, jf. f. eks.The horizontal arrangement of the valve seat in the floor drain entails, cf.
SE, B, 398 654, en lavere byggehøjde på gulvafløbet, men det kræver en meget stor kraft for at frigøre ventillegemet fra ventilsædet eftersom ventillegemet, til 15 forskel fra anordningen ifølge SE, B, 398 654, må løftes vinkelret mod ventilsædets plan.SE, B, 398 654, a lower building height on the floor drain, but it requires a very large force to release the valve body from the valve seat since, unlike the device according to SE, B, 398 654, the valve body must be lifted perpendicular to the plane of the valve seat.
For med en mindre kraft at tillade frigørelsen af ventillegemet fra ventilsædet og samtidigt yderligere fremhæve bestræbelsen at give gulvafløbet lav byggehøjde 20 er ventillegemet desuden fortrinsvist udformet som en plade med en relativt stor overflade, som kan påvirkes af væske, og er anbragt således, at en del deraf befinder sig excentrisk i forhold til ventilsædet, hvilken del, når ventillegemet påvirkes af væske, først begynder at røre på sig, eftersom denne del ikke påvirkes af undertrykket i vakuumsystemet i samme udstrækning som de dele af ventille-25 gemet der er nærmere eller ligefrem over ventilsædet. Herved opnås den nævn-te brydeeffekt.In addition, in order to allow the release of the valve body from the valve seat with a lesser force and at the same time further emphasize the effort to give the floor drain a low building height 20, the valve body is also preferably formed as a plate with a relatively large surface which can be influenced by liquid, and is arranged so that a part thereof is eccentric to the valve seat, which portion, when the valve body is affected by fluid, does not begin to move, since that portion is not affected by the vacuum in the vacuum system to the same extent as the parts of the valve body which are closer or straight across the valve seat. Hereby the said breaking effect is obtained.
Endelig opnås gennem afstandsorganeme, at ventillegemet holdes horisontalt for optimal tætning mod det horisontalt anbragte ventilsæde.Finally, through the spacers, the valve body is maintained horizontally for optimum sealing against the horizontally disposed valve seat.

Ovennævnte og øvrige træk, som er kendetegnende for opfindelsen, samt formål og fordele derved, fremgår nærmere af den efterfølgende beskrivelse af opfindelsen med henvisning til de ledsagende tegninger, hvor: 5 Fig. 1 er et planbillede af et gulvafløb med en ventilindretning ifølge opfin- ' delsen, og fig. 2-4 er lodrette snit gennem gulvafløbet med ventilindretningen ifølge fig. 1 og viser ventilindretningen i forskellige funktionsstillinger.The foregoing and other features which characterize the invention, as well as objects and advantages thereof, will become more apparent from the following description of the invention with reference to the accompanying drawings, in which: 1 is a plan view of a floor drain with a valve device according to the invention; and FIG. 2-4 are vertical sections through the floor drain with the valve assembly of FIG. 1 and shows the valve assembly in various operating positions.
10 På tegningens figurer vises således et gulvafløb 1, som er sluttet til et (ikke vist) vakuumsystem af konventionel art til at suge indholdet ud af gulvafløbet. Vakuumsystemet er konstant i drift for at frembringe denne udsugning. Gulvafløbet 1 kan være af enhver egnet art for tilslutning til et vakuumsystem og af ethvert eg-15 net materiale.10 thus shows a floor drain 1 connected to a conventional (not shown) vacuum system for sucking the contents out of the floor drain. The vacuum system is constantly operating to produce this suction. The floor drain 1 may be of any suitable type for connection to a vacuum system and of any suitable material.
En ventilindretning 2 er anbragt i gulvafløbet 1. Ventilindretningen 2 tilslutter gulvafløbets 1 forbindelse med vakuumsystemet, det vil sige udløbet 3 fra gulvafløbet, og åbner forbindelsen, når den påvirkes af væske, som løber ned i gulvaf-20 løbet, så undertrykket i vakuumsystemet kan suge væsken ud af gulvafløbet.A valve device 2 is arranged in the floor drain 1. The valve device 2 connects the floor drain 1's connection with the vacuum system, that is, the outlet 3 from the floor drain, and opens the connection when it is influenced by liquid running down the floor drain, so that the vacuum in the vacuum system can suck the liquid out of the floor drain.
Ventilindretningen 2 omfatter et ventilsæde 4, som er monteret ved gulvafløbets 1 udløb 3, og et ventillegeme 5, der er bevægbart anbragt i gulvafløbet. Ventillegemet 5 samvirker derved med ventilsædet 4 og lukker udløbet 3, når gulvaflø-25 bet 1 er tømt for vand. Ventillegemet 5 påvirkes desuden af væske, som løber ned i gulvafløbet 1, så udløbet 3 åbnes ved at ventillegemet flyttes i forhold til ventilsædet 4.The valve assembly 2 comprises a valve seat 4 mounted at the outlet 3 of the floor drain 1 and a valve body 5 movably arranged in the floor drain. The valve body 5 thus cooperates with the valve seat 4 and closes the outlet 3 when the floor drain 1 is emptied of water. The valve body 5 is additionally affected by liquid flowing into the floor drain 1, so that the outlet 3 is opened by moving the valve body relative to the valve seat 4.
Undertrykket i vakuumsystemet medvirker til at holde udløbet 3 lukket og, når 30 ventillegemet 5 af væske, der løber ned i gulvafløbet 1, påvirkes til at åbne udløbet, sker dette mod kraften fra undertrykket i vakuumsystemet. Udløbet 3 og ven- 6 DK 174868 B1 tilindretningen 2 kan anbringes på ethvert egnet sted i gulvafløbet 1, for eksempel i bunden af gulvafløbet, hvor undertrykket i vakuumsystemet henholdsvis væsken, som løber ned i gulvafløbet, tillades at påvirke ventillegemet 5 på den angivne måde. Med henblik på ved hjælp af en enkel, direkte styret og hurtigt 5 reagerende ventilindretning hurtigt og enkelt at lette åbningen af udløbet 3 mod kraften fra undertrykket i vakuumsystemet har ventillegemet 5 ifølge opfindelsen ' en excentrisk i forhold til ventilsædet 4 anbragt del 5a (fortrinsvis mindst 10 cm afstand mellem delen 5a og ventilsædets 4 centrum), som flyttes på en sådan måde, når den påvirkes af væske, at den med en slags brækkevirkning, som for-10 stærkes af excentriciteten, vrider ventillegemet bort fra dets tætnende anlæg mod ventilsædet. I den på tegningerne viste udførelsesform flyttes ventillegemet 5 derved fra stillingen ifølge fig. 2 til stillingen ifølge fig. 3.1 stillingen ifølge fig. 3 er ventillegemet 5 gennem vridningen bragt bort fra dets tætnende anlæg mod ventilsædet 4 ved dettes ene side, så væske nu kan begynde at løbe ud via ud-15 løbet 3. Ventillegemet 5 er anbragt til at løftes helt fra ventilsædet 4 efter den indledende vridning (til stillingen ifølge fig. 3) i forhold til ventilsædet, og så væsken løfter nævnte del 5a af ventillegemet og/eller ventillegemet yderligere. Stillingen, hvor ventillegemet 5 således helt har forladt sit tætnende anlæg mod ventilsædet 4 vises på fig. 4. Væske kan nu frit strømme ned i udløbet 3, som er helt 20 åbent.The vacuum in the vacuum system helps to keep the outlet 3 closed and, when the valve body 5 of liquid flowing into the floor drain 1 is influenced to open the outlet, this is done against the force of the vacuum in the vacuum system. The outlet 3 and the device 2 can be arranged at any suitable location in the floor drain 1, for example at the bottom of the floor drain, where the vacuum in the vacuum system or the liquid flowing into the floor drain, respectively, is allowed to influence the valve body 5 in the manner indicated. . In order to quickly and easily facilitate the opening of the outlet 3 against the force from the vacuum in the vacuum system by means of a simple, directly controlled and rapidly reacting valve device, the valve body 5 according to the invention has an eccentric relative to the valve seat 4 located at part 5a (preferably at least 10 cm distance between the part 5a and the center of the valve seat 4), which is moved in such a way that it is influenced by liquid, that with a kind of breaking action which is enhanced by the eccentricity, the valve body turns away from its sealing abutment towards the valve seat. In the embodiment shown in the drawings, the valve body 5 is thereby moved from the position of FIG. 2 to the position of FIG. 3.1 the position of FIG. 3, the valve body 5 is removed from its sealing abutment through the torsion towards the valve seat 4 on one side thereof, so that liquid can now start to flow out through the outlet 3. The valve body 5 is arranged to be lifted completely from the valve seat 4 after the initial rotation. (to the position of Fig. 3) relative to the valve seat, and then the liquid lifts said portion 5a of the valve body and / or valve body further. The position whereby the valve body 5 has thus completely left its sealing system against the valve seat 4 is shown in FIG. 4. Liquid can now freely flow down into the outlet 3, which is fully open.
I den på tegningerne viste foretrukne udførelsesform består ventillegemet af et hullegeme 5, som på den ene side af en centrumlinie CL danner nævnte del 5a og på den anden side af centrumlinien CL udviser en anden del 5b, der samvir-25 ker med ventilsædet 4. Hullegemet 5 er fortrinsvis, lige som på tegningerne, for-møt som en plade og fortrinsvis anbragt liggende (helst vandret eller i hovedsagen vandret) i gulvafløbet 1. Hullegemet 5 er fortrinsvis desuden cirkelformet, det vil sige at i udførelsen med pladeformet hullegeme 5 er pladen følgelig rund. Hullegemet 5 kan dog ligeledes have anden for funktionen egnet eller efter gulvaflø-30 bet 1 tilpasset form, for eksempel være andet end pladeformet, for eksempel sfærisk, henholdsvis være andet end rund, for eksempel rektangulær eller kva- 7 DK 174868 B1 dratisk. Alternativt er det også muligt, at ventillegemet 5, især hvis dette er udformet som en tynd plade af passende materiale med lav vægt, for eksempel en skumplast, ikke er et hullegeme. Hullegemet 5 er i den viste udførelsesform anbragt i en cirkelformet del 1a af gulvafløbet 1. Hullegemet 5 er fortrinsvis også 5 anbragt centreret med gulvafløbsdelen 1a (centrumlinien CL er fælles for begge r disse dele) og derved passende ligeledes udformet med en noget mindre diame ter end gulvafløbsdelen, så hullegemet 5 under sine løfte- og sænkebevægelser på en vis måde styres af nævnte gulvafløbsdel og altid havner i rette stilling ved tilbagevenden til tætnende anlæg mod ventilsædet 4, uanset hvor i gulvafløbets 10 1 bund 1aa ventilsædet er anbragt. Ventilsædet 4 er derimod, for opnåelse af den ovenfor beskrevne åbning af udløbet 3 i to trin, fortrinsvis excentrisk anbragt i forhold til gulvafløbets 1 cirkulære del 1a og dermed også til ventillege-met/hu I legemet 5. Ventillegemets udformning som et hullegeme er naturligvis foranlediget af, at væske derved lettere kan påvirke samme. Hullegemet 5 flyder 15 i princippet på væskeoverfladen, hvorfor det desuden reagerer hurtigt på væske, der begynder at løbe ned i gulvafløbet 1.In the preferred embodiment shown in the drawings, the valve body consists of a hollow body 5 which forms on one side of a center line CL, said part 5a and on the other side of the center line CL, another part 5b which cooperates with the valve seat 4. The hollow body 5 is preferably, as in the drawings, anchored as a plate and preferably disposed (preferably horizontally or substantially horizontally) in the floor drain 1. The hollow body 5 is preferably also circular, i.e. in the embodiment with plate-shaped hollow body 5 is the plate accordingly round. However, the hollow body 5 may also have other shape suitable for the function or adapted to the floor drain 1, for example, be other than plate-shaped, for example spherical, or be other than round, for example rectangular or quadratic. Alternatively, it is also possible that the valve body 5, especially if formed as a thin sheet of suitable lightweight material, for example a foam plastic, is not a hollow body. The hollow body 5 is in the illustrated embodiment disposed in a circular part 1a of the floor drain 1. The hollow body 5 is also preferably 5 centered with the floor drain part 1a (the center line CL is common to both of these parts) and thus suitably also formed with a somewhat smaller diameter. than the floor drain part, so that the hollow body 5 during its lifting and lowering movements is controlled in a certain way by said floor drain part and always ends in the correct position upon return to sealing systems against the valve seat 4, regardless of where the valve seat of the floor drain 10 1 is located. The valve seat 4, on the other hand, for obtaining the above-described opening of the outlet 3 in two stages, is preferably eccentrically disposed with respect to the circular part 1a of the floor drain 1 and thus also to the valve body / housing in the body 5. The design of the valve body as a hollow body is, of course, caused by the fact that liquid can more easily affect the same. The hollow body 5 flows 15 in principle on the liquid surface, which is why it also responds quickly to liquid that starts to run down into the floor drain 1.
I den foretrukne udførelsesform ifølge tegningerne dannes ventilsædet 4 af en rørdel 6, som skyder ind i gulvafløbet 1 (delen 1a deraf) og er sluttet til vakuum-20 systemet, det vil sige ligeledes danner udløbet 3 fra gulvafløbet. Rørdelen 6 skyder her ind i gulvafløbet 1 fra undersiden, via gulvafløbets bund 1aa. En ende-kant 6a på rørdelen 6 og/eller en på rørdelen anbragt tætningsring 7 danner herved ventilsædet 4. Tætningsringen 7 giver naturligvis en bedre tætning, eftersom denne er elastisk og kan give noget efter, når ventillegemet 5 først og f 25 fremmest af undertrykket i vakuumsystemet holdes i tætnende anlæg mod ventilsædet 4.In the preferred embodiment according to the drawings, the valve seat 4 is formed by a pipe part 6 which projects into the floor drain 1 (part 1a thereof) and is connected to the vacuum system, that is, the outlet 3 also forms from the floor drain. The pipe portion 6 here slides into the floor drain 1 from the underside, via the floor drain bottom 1aa. An end edge 6a of the pipe member 6 and / or a sealing ring 7 arranged on the pipe member thereby forms the valve seat 4. The sealing ring 7 naturally provides a better seal, since it is elastic and can give some when the valve body 5 first and foremost of the negative pressure in the vacuum system are kept in sealing systems against the valve seat 4.
Rørdelen 6 kan være anbragt på en sådan måde, at dens endekant 6a eller tætningsringen 7 i princippet ligger i niveau med gulvafløbets 1 bund 1aa i den viste 30 udførelsesform. Den kan også skyde et stykke ind i gulvafløbet 1 i den cirkelformede del 1a deraf. Eftersom rørdelen 6 gennem sin funktion som ventilsæde i 8 DK 174868 B1 den viste udførelsesform fortrinsvis er anbragt excentrisk i gulvafløbsdelen 1a, skydende opad fra gulvafløbets 1 bund 1aa, og ventillegemet 5 ved anlæg mod ventilsædet 4 derved bør indtage en vandret eller i hovedsagen vandret stilling i gulvafløbet for maksimal tætning mod ventilsædet, er der passende anbragt 5 mindst to afstandsstykker 8 i gulvafløbet. Afstandsstykkeme 8 er anbragt på gulvafløbets 1 bund 1aa og skyder opad fra denne til en højde, der svarer til den ' strækning, som rørdelen 6 skyder ind i gulvafløbet. Ventillegemet 5 har derved mindst tre punkter, på hvilke den hviler vandret eller i hovedsagen vandret, når gulvafløbet 1 er tomt, nemlig de to afstandsstykker 8 og ventilsædet 4, der er 10 dannet af rørdelen 6 (rørdelens 6 endekant 6a og/eller tætningsringen 7 derpå).The pipe portion 6 may be arranged in such a way that its end edge 6a or the sealing ring 7 is in principle aligned with the bottom 1aa of the floor drain 1 in the embodiment shown. It can also slide into the floor drain 1 in the circular portion 1a thereof. Since the pipe part 6, through its function as a valve seat in the illustrated embodiment, is preferably placed eccentrically in the floor drain part 1a, pushing upwards from the bottom 1aa of the floor drain 1, and the valve body 5 in contact with the valve seat 4 should thereby assume a horizontal or substantially horizontal position. in the floor drain for maximum seal against the valve seat, there are suitably placed at least two spacers 8 in the floor drain. The spacers 8 are arranged on the bottom 1aa of the floor drain 1 and shoot upwards from it to a height corresponding to the distance that the pipe part 6 projects into the floor drain. The valve body 5 thus has at least three points on which it rests horizontally or substantially horizontally when the floor drain 1 is empty, namely the two spacers 8 and the valve seat 4 formed by the pipe part 6 (the end edge 6a of the pipe part 6 and / or the sealing ring 7 then).
Flytningen af ventillegemets 5 nævnte ene del 5a for vridning af ventillegemet bort fra dets tætnende anlæg mod ventilsædet samt den efterfølgende løftebevægelse hos ventillegemet begrænses passende af et gulvafløbet 1 anbragt an-15 slagsorgan 9. Anslagsorganet består i den viste udførelsesform af en noget hvælvet og cirkelformet kappelignende del 9, som fra oven dækker hele ventillegemet. Den kappeformede del 9 er fastklemt i den nævnte cirkulære del 1a af gulvafløbet 1. Dette frembringes passende ved at den kappeformede dels 9 kantparti 9a bøjes nedad, og kantpartiet trykkes ned i gulvafløbets nævnte cirku-20 lære del 1 a, hvorved kantpartiet gennem forspændingen deri ligger an med en vis trykkraft mod sidevæggen 1ab til den nævnte cirkulære del af gulvafløbet.The movement of the valve body 5 mentioned part 5a for twisting the valve body away from its sealing abutment towards the valve seat and the subsequent lifting movement of the valve body is suitably limited by a floor drain 1 arranged abutment member 9. The abutment means in the illustrated embodiment consists of a somewhat vaulted and circular shape. sheath-like part 9, which covers the entire valve body from above. The casing portion 9 is clamped in said circular portion 1a of the floor drain 1. This is conveniently provided by the edge portion 9a of the casing portion 9a being bent downwardly and the edge portion being pressed down into said circular portion 1a of the floor drain, the edge portion through the biasing therein. abuts with a certain compressive force against the side wall 1ab to said circular part of the floor drain.
Med udgangspunkt fra det nedadbøjede kantparti 9a har kappedelen 9 således en diameter, der i hovedsagen svarer til diameteren på den nævnte cirkulære del 1a af gulvafløbet 1. Øvrige partier 9b af den kappeformede del 9 forløber i den 25 viste udførelsesform opad og ind i gulvafløbets 1 cirkelformede del 1 b, der udvi- ^ ser en klemring 10 og si 11. Anslagsorganet 9 er kappeformet og dækker hele ventillegemet 5 oppefra fortrinsvis for at beskytte ventillegemet mod tilsmudsning og bibringer nødvendig bevægelse af denne i gulvafløbet 1 (fortrinsvis i den cirkelformede del deraf). For at væske skal kunne løbe forbi anslagsorganet i gulv-30 afløbet 1, er kantpartiet 9a på den kappeformede del 9 ligeledes forsynet med udtagninger 12. Udtagningerne 12 er altså anbragt periferielt og er i en vis ud- g DK 174868 B1 strækning begrænset radialt for om muligt at forhindre tilsmudsning af ventillegemet 5, men naturligvis kan udtagningerne, hvis det ønskes, udformes på anden måde og/eller optages som huller i andre partier 9b af den kappeformede del 9.Thus, starting from the downwardly curved edge portion 9a, the casing portion 9 has a diameter substantially corresponding to the diameter of said circular portion 1a of the floor drain 1. Other portions 9b of the casing portion 9 extend upwardly into the floor drain 1 in the illustrated embodiment. circular portion 1b, extending a clamping ring 10 and s. 11. The abutment member 9 is sheath-shaped and preferably covers the entire valve body 5 from above to protect the valve body from contamination and provides necessary movement thereof in the floor drain 1 (preferably in the circular portion thereof). ). In order for fluid to pass through the abutment member in the floor 30 drain 1, the edge portion 9a of the casing part 9 is also provided with recesses 12. The recesses 12 are thus arranged peripherally and in a certain extent are limited radially for if possible, to prevent fouling of the valve body 5, but of course, the recesses, if desired, can be designed differently and / or received as holes in other portions 9b of the sheath-shaped part 9.
5 f Yderligere kan man, uanset om et anslagsorgan er anbragt eller ej, og uanset om anslagsorganet 9 er udformet som en kappe eller på anden måde, udforme sien 11 med modsvarende periferielle udtagninger eller huller 13 (se fig. 1) og for øvrigt uden spalter eller huller for at forhindre tilsmudsning af ventiliegemet 5.Further, whether or not an impact member is disposed and whether the impact member 9 is formed as a cap or otherwise, the sieve 11 can be formed with corresponding peripheral recesses or holes 13 (see Fig. 1) and otherwise without slots or holes to prevent fouling of the valve body 5.
10 Savnes separate anslagsorganer fungerer sien 11 også som et sådant og begrænser ventillegemets 5 opad rettede bevægelse.10 Missing separate stop means 11 also act as such, limiting the upward movement of the valve body 5.
Det er åbenbart for fagmanden, at den foreliggende opfindelse kan modificeres og ændres inden for rammerne af de efterfølgende patentkrav uden at fravige 15 opfindelsens idé og formål. Således er det klart, at placering og udformning af ventilindretningen i gulvafløbet kan være en anden ende den oven for beskrevne og på tegningerne viste, ligesom naturligvis udformningen af selve gulvafløbet. Ventilindretningens ventillegeme kan være udformet på anden måde, ligesom først og fremmest den del deraf, som påvirkes af væskeniveauet i gulvafløbet.It will be apparent to those skilled in the art that the present invention may be modified and modified within the scope of the appended claims without departing from the spirit and scope of the invention. Thus, it is clear that the location and design of the valve device in the floor drain may be a different end than that described above and in the drawings, as is of course the design of the floor drain itself. The valve body of the valve device may be configured in a different way, as is the portion thereof which is affected by the liquid level in the floor drain.
20 Ventilindretningens ventilsæde kan også udover det, som fremgår oven for, udformes og anbringes på anden måde, og ligeledes i et vist omfang ventillegemets og ventilsædets indbyrdes placering. Gulvafløbets udløb er der også mulighed for at placere og udforme anderledes. Vedrørende materialevalget til gulvafløbet og ventilindretningen findes der også et vist spillerum, det vil sige en egnet 25 plast eller metal.The valve seat of the valve device can also, in addition to what is stated above, be designed and arranged in a different way, and also to a certain extent the position of the valve body and the valve seat. The outlet of the floor drain is also possible to place and design differently. Regarding the choice of material for the floor drain and the valve device, there is also a certain leeway, that is, a suitable plastic or metal.
