Description
Au torna t-isk trykkutjevningsventil for luftl*edningssystemer Automatic pressure equalization valve for air duct systems
En automatisk trykkutjevningsventil for luftledning?-systemer utgjor en anordning som monteres på et ledningssy stem for å tilveiebringe lufting av systemet ved at forurenset og illeluktende luft hindres i å trenge ut, samtidig som t ryk k u t j e vn i n g s - ventilen ved undertrykk åpnes automatisk og slipper friskluft inn i ledningssysternet. An automatic pressure equalization valve for air line? systems is a device that is mounted on a line system to provide ventilation of the system by preventing contaminated and malodorous air from escaping, while at the same time the pressure equalization valve opens automatically in the event of negative pressure and releases fresh air into the wiring system.
I overensstemmelse med de bestemmelser som gjelder for lufting av sanitære anlegg,er det tidligere fastlagt at lufte-ledninger fra avl bpse ri heter skal forbindes med klosettstolens ovre avlbp og ledes opp gjennom bjelkelag og yttertak, hvor led-ningei normalt avsluttes med et 180° rbrbend eller med et luftavlop so,m har direkte åpning til atmosfæren. In accordance with the regulations that apply to the ventilation of sanitary facilities, it has previously been established that ventilation lines from the avl bpser must be connected to the toilet seat's upper avlbp and led up through joists and the outer ceiling, where the line normally ends with a 180° rbrbend or with an air drain so,m has a direct opening to the atmosphere.
Disse 1 uftesy s terner er beheftet med betydelige ulemper, dels fordi tetningen mellom det ytre takskikt og lufteledningen er kostbar og krever spesielle arrangementer for at tetningen skal bli effektiv, dels fordi det fra et estetisk synspunkt må anses mindre tiltalende med den slags gjennomgående ledninger som rager opp gjennom moderne og pent formede tak, og dels fordi man ikke kan unngå 'en ytre luftforurensning. These 1 ventilation systems are fraught with significant disadvantages, partly because the seal between the outer roof layer and the ventilation pipe is expensive and requires special arrangements for the seal to be effective, partly because from an aesthetic point of view it must be considered less appealing with the kind of continuous pipes that jutting up through modern and nicely shaped roofs, and partly because you cannot avoid external air pollution.
For å eliminere disse ulemper er der kommet nye bestemmelser som innebærer at 1ufteledninger kan avsluttes innendbrs, forutsatt at ledningen er forsynt med en automatisk lufteventil som ikke slipper :ut forurenset luft, men åpner for luftadgang når der under spylingen av klosettet oppstår undertrykk i ledningen. In order to eliminate these disadvantages, new regulations have been introduced which mean that air ducts can be terminated within a short period of time, provided that the duct is equipped with an automatic vent valve that does not release contaminated air, but allows air access when negative pressure occurs in the duct during flushing of the toilet.
Som folge av disse nye bestemmelser er enkelte anord-ninger med tilbakeslagsventiler blitt kjent for på automatisk måte å lose luftingen av sådanne 1 edningssysterner. Disse kjente kon-, struksjoner som bygger på konvensjonelle mekaniske funksjoner, er etter kort tid blitt ubrukelige, da den aggressive atmosfære temmelig hurtig bevirker korrosjon av de mekaniske deler. Ved lave temperaturer har også isdannelse hindret disse ventiler i å virke. Andre allerede kjente konstruksjoner, hvor tilbakeslags-ventilen består av en tynn slange av plast eller elastomert materiale som er traktformet oventil og flattrykt nedentil for at den flattrykte slangedel skal åpnes ved undertrykk og gjennom trakten tilfore systemet luft, men lukkes ved trykkutjevning, således at den forurensede luft ikke trenger ut, vil på kort tid opphore å virke så snart den flattrykte slangedel ved lufttilførsel er blitt belagt innvendig med en fuktig hinne som bevirker at slangen klebes sammen . As a result of these new provisions, certain devices with non-return valves have become known to automatically release the aeration of such 1-line cisterns. These known constructions, which are based on conventional mechanical functions, have become unusable after a short time, as the aggressive atmosphere rather quickly causes corrosion of the mechanical parts. At low temperatures, ice formation has also prevented these valves from working. Other already known constructions, where the non-return valve consists of a thin hose made of plastic or elastomeric material which is funnel-shaped at the top and flattened at the bottom so that the flattened hose part is opened under negative pressure and air is supplied to the system through the funnel, but is closed when the pressure equalises, so that contaminated air does not penetrate, will in a short time cease to work as soon as the flattened hose part during the air supply has been coated inside with a moist film which causes the hose to stick together.
Hensikten med, oppfinnelsen er å eliminere disse ulemper og tilfredsstille de gjeldende bestemmelser. Nærmere bestemt angår oppfinnelsen således en automatisk trykkutjevningsventil for 1uft1edningssysterner, særlig for sanitære a vi bp s 1 edni n ger, for å hindre at forurenset og illeluktende luft skal lekke ut av led-nings sy s t erne t , men som ved undertrykk i dette, f. eks. ved spyling av vannklosetter, slipper ny luft inn i systemet. Det særegne ved oppfinnelsen fremgår av de etterfblgende krav. The purpose of the invention is to eliminate these disadvantages and satisfy the applicable provisions. More specifically, the invention thus relates to an automatic pressure equalization valve for ventilation systems, in particular for sanitary avi bps 1 buildings, to prevent polluted and foul-smelling air from leaking out of the line system, but as in the case of negative pressure in this, e.g. when flushing water toilets, new air is allowed into the system. The peculiarity of the invention appears from the following claims.
Ved den nye trykkutjevningsventil som har en enkel og billig konstruksjon, oppnås en sikker funksjon, således at forurenset luft som måtte være tilbake i 1edningssystemet, ikke har mulighet for å lekke ut fra 1edningssysterne ts utlbp. Anordningen kan dertil monteres i nær tilslutning til 1edningssysternets luftutlbp og på frostfrittnivå eller på luftledningens utlbp når denne befinner seg under yttertaket ved uisolerte rom, idet anordningen i sistnevnte tilfelle må forsynes med et lag av porbst skummateriale for at faren for frostdannelse skal elimineres. With the new pressure equalization valve, which has a simple and inexpensive construction, a safe function is achieved, so that contaminated air that may be left in the piping system does not have the opportunity to leak out from the piping system's outlet. The device can also be mounted in close connection to the air outlet of the piping system and at a frost-free level or on the outlet of the air line when this is located under the outer ceiling in uninsulated rooms, as the device in the latter case must be provided with a layer of porous foam material in order to eliminate the risk of frost formation.
Oppfinnelsen skal beskrives nærmere under henvi sning ..ti 1 et på tegningen i snitt vist u t f br el s e s ek s em.pel . The invention is to be described in more detail under reference ..ti 1 et in the drawing in section shown out f br el s e x e x e m.pel.
Trykkutjevningsven ti lens hus 1 består av et vertikal t ror med et sirkulært uttak 2 i sideveggen. Gjennom dette uttak er der fort et rbrbend 3 som. er festet omkring uttaket 2, således at dets innvendige munning befinner seg horisontal og konsentrisk til huset 1. Oventil er dette hus dekket med et tettende og avtagbart lokk 4 og utvendig ved behov belagt med et porbst skummateriale 5, såsom polyuretanskum. Den indre diameter av trykk-ut j evn i n gs ven ti 1 en s hus 1 er således valgt at det kan tilkobles et lufterbr av standardtypen og er, da det er forsynt med isolerende skummateriale, i sin nedre ende ikke forsynt med sådant materiale for at den lett skal kunne festes til lufterbret." Trykkutjevriingsven ti 1 ens eneste bevegelige del består av en fortrinnsvis hul, halvsfærisk gummitetning 6 som tetter rbrbendets 3 indre åpning og som ved undertrykk i huset 1, f. eks. som folge av spyling, lbftes opp og slipper luft inn i rbrsystemet gjennom be-ndet 3. Ved utjevnet trykk mellom rorene lukkes rbrbendets indre åpning igjen av gummitetngen 6, således at forurenset luft hindres i å trenge ut av trykkutjevningsventilen. Pressure equalization valve housing 1 consists of a vertical tube with a circular outlet 2 in the side wall. Through this outlet there is quickly a rbrbend 3 which. is fixed around the outlet 2, so that its inner mouth is horizontal and concentric to the housing 1. The top of this housing is covered with a sealing and removable lid 4 and externally, if necessary, coated with a porous foam material 5, such as polyurethane foam. The inner diameter of the pressure equalization valve 1 en s housing 1 is chosen so that a standard-type air bridge can be connected and, as it is provided with insulating foam material, is not provided with such material at its lower end for that it should be easily attached to the air board." The only moving part of the pressure relief valve 1 consists of a preferably hollow, hemispherical rubber seal 6 which seals the inner opening of the rubber band 3 and which, in the event of negative pressure in the housing 1, e.g. as a result of flushing, up and lets air into the tube system through the tube 3. When pressure is equalized between the tubes, the tube's inner opening is closed again by the rubber seal 6, so that contaminated air is prevented from escaping through the pressure equalization valve.
