Description
Luftledningsventil for beskyttelsesrom. Air line valve for protection room.
Oppfinnelsen vedrører en luftledningsventil for beskyttelsesrom og går i første rekke ut på å oppnå to ting, nemlig å kunne øke lukkehastigheten og lukkesikkerheten ved opptredende eksplosjonstrykk og der-etter følgende sug, samtidig som ventilen skal yde den normale driftsstrømning minst mulig motstand. The invention relates to an air line valve for protective rooms and primarily aims to achieve two things, namely to be able to increase the closing speed and closing safety in the event of explosion pressure and subsequent suction, while at the same time the valve must offer the least possible resistance to the normal operating flow.
Disse to oppgaver løses i henhold til These two tasks are solved according to
oppfinnelsen ved at to ventiltalieirkener for vektutligning og for oppnåelse av særlig lett bevegelighet på samme måte som en vektbjelke, er lagret på en toarmet, svirag-bar bjelke, og at ventilsetene i lufttilløps-og avløpsledningen er således anordnet at den ene ventiltallerkenen lulkker luftledningen ved ytre trykk, mens den annen ventiltallerken lukker luftledningen ved ytre sug. the invention in that two valve plate plates for weight compensation and for achieving particularly easy mobility in the same way as a weight beam are stored on a two-armed, srivag-able beam, and that the valve seats in the air supply and discharge line are arranged in such a way that one valve plate closes the air line at external pressure, while the other valve disc closes the air line in case of external suction.
Den vektbjelkeaktige lagring av to ventiltallerkener har ikke bare den for en vekt karakteristiske, særlig lette bevegelighet, som er en stor fordel når det gjelder å oppnå hurtig lukking i katastrofetilfeller, samt hurtig og lett reaksjon, også når ventilen er utført som overtrykk- eller undert r ykk-ventil for den normale driftsstrømning. Videre har ventilen den fordel at ventiltallerkenene ved sin bevegelse undergår en sterk forandring med hensyn til sin høyde-stllling, dvs. de rager forskjellig langt inn i luftstrømmen, og ved utbalansert vektstilling ydeir luftstrømmen særlig liten motstand. The weight beam-like storage of two valve plates not only has the characteristic of a weight, especially light mobility, which is a great advantage when it comes to achieving rapid closure in disaster cases, as well as quick and easy reaction, also when the valve is designed as overpressure or underpressure r ykk valve for the normal operating flow. Furthermore, the valve has the advantage that during its movement the valve discs undergo a strong change with regard to their height position, i.e. they protrude different distances into the air flow, and with a balanced weight position the air flow offers particularly little resistance.
Dette er energisparende når det gjelder den normale strømning, såvel i lufttil-løps- som i luftavløpsledningene. Ved de hittil kjente beskyttelsesinnretninger mot eksplosjonstrykk- og sug og også ved de ventiler som åpner seg først ved normalt driftsovertrykk, vil der nemlig i luftavløps-ledningen opptre betydelige motstander, ikke bare på grunn. <av tverrsnittisinnisinev-ringene, men særlig også på grunn av de sterke og ofte skarpe ombøyminger av den normale strøm under drift. For å over-vinne disse motstander krever friskluft-tilsugningsinnretninigen et høyere energi-forbruk, hvilket kan ha alvorlige følger, særlig n'år ved svikt av den -elektriske ener-gi, betjeningen må foretas manuelt. This is energy-saving when it comes to the normal flow, both in the air supply and in the air outlet lines. With the previously known protection devices against explosion pressure and suction and also with the valves that open only at normal operating overpressure, considerable resistance will occur in the air discharge line, not only due to <of the cross-sectional innisinev-rings, but especially also due to the strong and often sharp deflections of the normal flow during operation. In order to overcome these resistances, the fresh air intake device requires a higher energy consumption, which can have serious consequences, especially when the electric power supply fails, the operation must be carried out manually.
I henhold til oppfinnelsen kan ventil-tallerknene være således anordnet i sin vektbjelkeaktige lagring at de i åpningsstil-linigen frigjør en del av tverrsnittet av den direkte forbindelse mellom innløps- og ut-løpsåpningen. Denne del kan utgjøre om-trent halvparten eller fortrinnsvis mere enn halvparten av luftledningstverrsnittet. I henhold til et annet forslag kan her ven-tiltallerknene være således utformet at de med sin overkant ikke over luftledningens midtakse rager inn i ledningen. I dette tilfelle bir der bare en meget liten motstand mot driftsstrømningen. Stillingen er imidlertid tilstrekkelig til ved en plutselig trykkstigning å bringe ventilen til å lukke seg. According to the invention, the valve discs can be arranged in their weight beam-like storage in such a way that they release part of the cross-section of the direct connection between the inlet and outlet opening in the opening position. This part can make up approximately half or preferably more than half of the air line cross-section. According to another proposal, the vein plates can be designed in such a way that their upper edge does not protrude above the central axis of the air duct into the duct. In this case, there is only a very small resistance to the operating current. However, the position is sufficient to cause the valve to close in the event of a sudden increase in pressure.
Den lette bevegelighet av den vektbjelkeaktige ventilutførelse gjør det også mulig i henhold til nok et trekk ved oppfinnelsen å forsyne en ventiltallerken med en så liten oveJrvekt, at når ventilen ikke er i virksomhet, lukker den ene ventiltallerken akkurat den ene ledningsåpning, mens allerede et lite overtrykk av den normale driftsstrømning tilveiebringer optimal ap-ningsstillimg. Således' oppfyller den samme innretning også funksjonen av em beskyttelsesrom-overtrykksventil i luftavløpsled- The easy movement of the weight beam-like valve design also makes it possible, according to yet another feature of the invention, to provide a valve plate with such a small excess weight that when the valve is not in operation, one valve plate closes exactly one line opening, while already a small overpressure of the normal operating flow provides optimal opening conditions. Thus, the same device also fulfills the function of a protective room overpressure valve in the air drainage line
