Ventil til fortrinsvis et affaldssugeanlæg samt fremgangsmåde til anvendelse af en sådan ventilValve for preferably a waste suction system and method for using such a valve

Omfang af opfindelsenScope of the Invention

Den foreliggende opfindelse angår en ventil til regulering af en massestrøm fortrinsvis 5 en affaldsmasse i et affaldssugeanlæg, omfattende et ventilkammer, en forskydelig ventilplade og en bevaegelsesenhed, hvor ventilkammeret i en ende er indrettet til placering imellem to rørender, og hvor nævnte bevægelsesenhed er placeret i en anden ende af ventilkammeret og indrettet til at forskyde nævnte ventilplade i nævnte ventilkammer fra en første lukket position til en anden åben position.The present invention relates to a valve for controlling a mass flow, preferably a waste mass in a waste suction system, comprising a valve chamber, a displaceable valve plate and a moving unit, the valve chamber being arranged at one end for placement between two pipe ends and wherein said moving unit is located in a second end of the valve chamber and adapted to displace said valve plate in said valve chamber from a first closed position to a second open position.

Opfindelsen angår endvidere et affaldssugeanlæg omfattende et rørsystem, et antal affaldsskakte og et antal af ovennævnte ventiler.The invention further relates to a waste suction system comprising a pipe system, a number of waste shafts and a number of the above-mentioned valves.

Den foreliggende opfindelse angår yderligere en fremgangsmåde til anvendelse af en l S ventil i et affaldssugeanlæg.The present invention further relates to a method of using a 1S valve in a waste suction system.

Baggrund for opfindelsen 20 I et moderne affaldsindsamlingssystem foregår indsamlingen af affald fra eksempelvis boligblokke ved hjælp af et fuldautomatisk og lukket system, der efter affaldsindsamling tømmes ved hjælp af vakuum til enten en fælles container eller en lignende fælles beholder.BACKGROUND OF THE INVENTION In a modern waste collection system, waste collection from, for example, residential blocks is carried out by means of a fully automatic and closed system which, after waste collection, is emptied by vacuum to either a common container or a similar common container.

25 Affaldet smides i eksempelvis affaldsskakte eller indkast, hvorunder der er placeret et affaldsmagasin, som kan opbevare affaldet, indtil affaldsmagasinet tømmes.25 The waste is thrown into, for example, trash cans or thrown under which is placed a waste bin which can store the waste until the waste bin is emptied.

For at forhindre at der forekommer lugtgener fra affaldet i affaldsmagasinet ud til brugerne af affaldsindsamlingssystemet er affaldsmagasinet forsynet med ventiler, DK 175979 B1 2 som både lukker affaldet tilnærmelsesvis lufttæt inde i affaldsmagasinet og afspærrer ud til affaldsindsamlingssystemets rørsystem.To prevent odor nuisance from the waste in the waste bin to the users of the waste collection system, the waste bin is provided with valves, DK 175979 B1 2 which both close the waste approximately airtight inside the waste bin and shut off to the waste collection system.

Når affaldet tømmes fra affaldsskakten ved hjælp af vakuum, skal ventilen i 5 afgangsåbningen åbnes, og der skal tilsættes transportluft til affaldsmagasinet for at luftstrømmen kan løsne og transportere affaldet væk.When the waste is emptied from the waste shaft by means of a vacuum, the valve in the outlet opening must be opened and transport air must be added to the waste container in order for the airflow to release and transport the waste away.

I den internationale patentansøgning WO 00/46129 er der beskrevet et system, hvor der anvendes en "refuse discharge valve” (RDV) sammen med et rørsystem for 10 indtagelse af transportluft i affaldsmagasinet, således at affaldet kan løsnes og transporteres bort.International patent application WO 00/46129 discloses a system using a "refuse discharge valve" (RDV) in conjunction with a piping system for the intake of transport air into the waste bin so that the waste can be released and transported away.

En ulempe ved dette system er, at der skal anvendes en del rørføring, ekstra rørsamlinger og teknikker for, at det kan fungere tilfredsstillende og derved bevirke, at 15 affaldet løsnes og transporteres videre.A disadvantage of this system is that some piping, extra pipe joints and techniques have to be used for it to function satisfactorily and thereby cause the waste to be unloaded and transported further.

En anden ulempe ved dette system er, at RDV-ventilen ikke er selvrensende, hvilket betyder, at der er risiko for, at der samler sig affaldsmateriale og væske i bunden af ventilkammeret, som med tiden forårsager nedbrud af ventilpladen, hvilket reducerer 20 effektiviteten af RDV-venti len.Another disadvantage of this system is that the RDV valve is not self-cleaning, which means that there is a risk of waste material and liquid accumulating at the bottom of the valve chamber, which over time causes the valve plate to break, reducing the efficiency of the valve plate. The RDV valve.

Det er specielt i mellemrummet mellem rørender af det tilstødende rørsystem, at affaldsmaterialet kan falde ned i ventilkammeret, og der sker efterfølgende en ophobning af materiale, der kan forhindre ventilpladen i at lukke 100 % tæt, når 25 affaldsmagasinet skal anvendes til opsamling af affald.It is especially in the space between pipe ends of the adjacent pipe system that the waste material can fall into the valve chamber, and subsequently there is an accumulation of material that can prevent the valve plate from closing 100% when the waste bin is to be used for waste collection.

Endvidere vil væske, der trænger ned i mellemrummet mellem rørender og ventil kammeret medføre, at ventilpladen i en lukket position vil befinde sig i et aggressivt miljø, der langsomt tærer ventilpladen og ventilkammeret, hvilket 30 medfører, at levetiden af ventilen reduceres væsentligt.Furthermore, liquid penetrating into the gap between the pipe ends and the valve chamber will cause the valve plate to be in a closed position in an aggressive environment that slowly degrades the valve plate and the valve chamber, which substantially reduces the life of the valve.

Disse ulemper er til dels anerkendt i beskrivelsen i den internationale patentansøgning WO 00/46129, men løsningen med at tilsætte transportluft i en rørsamling lige foran 3 DK 175979 B1 RDV-ventilen ændrer ikke ved, at der skal anvendes en del rørføring, ekstra rørsamlinger og teknikker, og at RDV-ventilen ikke er selvrensende.These disadvantages are partly recognized in the description in the international patent application WO 00/46129, but the solution of adding transport air in a pipe joint directly in front of 3 DK 175979 B1 The RDV valve does not change the use of some pipe routing, extra pipe joints and techniques and that the RDV valve is not self-cleaning.

5 Formål med opfindelsenObjects of the Invention

Det er formålet med den foreliggende opfindelse at angive en ventil til fortrinsvis affaldssugeanlæg, hvor denne ventil er enkelt udformet, selvrensende og automatisk virkende under funktion.SUMMARY OF THE INVENTION It is an object of the present invention to provide a valve for preferably waste suction systems, wherein this valve is simply designed, self-cleaning and automatically operating.

1010

Dette opnås ved hjælp af en ventil, som er beskrevet i den indledende del af krav 1, og hvor nævnte ventilkammer er udformet med et antal lufttilgange, der er indrettet til at lede sekundær transportluft ind igennem nævnte ventil.This is achieved by means of a valve as described in the preamble of claim 1, wherein said valve chamber is provided with a plurality of air inlets arranged to pass secondary conveying air through said valve.

2020

Et yderligere formål med den foreliggende opfindelse er at angive en fremgangsmåde til anvendelse af ventilen ifølge den foreliggende opfindelse i et affaldssugeanlæg.A further object of the present invention is to provide a method for using the valve of the present invention in a waste suction system.

25 Beskrivelse af opfindelsenDescription of the Invention

For at frembringe en enkelt udformet ventil anvendes en ventil i form af en skydeventil, der omfatter et ventilkammer, en forskydelig ventilplade og en bevægelsesenhed, hvor ventilkammeret omslutter den forskydelige ventilplade, som 30 forskydes ved hjælp af bevægelscsenheden.In order to produce a single shaped valve, a valve in the form of a sliding valve comprising a valve chamber, a displaceable valve plate and a moving unit is used, the valve chamber enclosing the displaceable valve plate which is displaced by the moving unit.

Ventilkammeret er endvidere indrettet for tilslutning mellem to rørender, således at rørendernes samling foregår indvendigt i ventilkammeret. For at der skal være plads til 4 DK 175979 B1 ventilpladen samles rørenderne således, at der efterlades et mellemrum imellem rørender, hvorigennem ventilpladen kan forskydes for at lukke for massestrømmen i rørsystemet.The valve chamber is further arranged for connection between two pipe ends, so that the pipe ends assembly takes place inside the valve chamber. To allow space for the valve plate 4, the pipe ends are assembled such that a gap is left between pipe ends, through which the valve plate can be displaced to close the mass flow in the pipe system.

5 Bevægelsesenheden, der forårsager forskydningen af ventilpladen i ventilkammeret kan være en cylinder, et mekanisk arrangement eller lignende, som hurtigt og nemt kan forskyde ventilpladen.The moving unit causing the displacement of the valve plate in the valve chamber may be a cylinder, a mechanical arrangement or the like, which can quickly and easily displace the valve plate.

I en foretrukket udførelsesform af den foreliggende opfindelse er bevægelsesenheden 10 en pneumatisk drevet cylinder, som er monteret på ventilkammeret og forbundet til ventilpladen.In a preferred embodiment of the present invention, the moving unit 10 is a pneumatically driven cylinder mounted on the valve chamber and connected to the valve plate.

Alternativer til en pneumatisk drevet cylinder kan være andre typer cylindere, der eksempelvis er drevet ved hjælp af elektricitet, hydraulik eller lignende, eller et 15 mekanisk arrangement, eksempelvis en tandstang/tandhjulsenhed der er drevet ved hjælp af en motorenhed.Alternatives to a pneumatically driven cylinder may be other types of cylinders driven, for example, by electricity, hydraulics or the like, or a mechanical arrangement, for example, a rack / pinion unit driven by a motor unit.

For at kunne lukke affaldsmagasinet af er ventilen indrettet således, at ventilpladen kan forskydes i ventilkammeret fra en første lukket position til en anden åben position, 20 i enten en variabel kontinuerlig bevægelse eller i trin.In order to be able to close the waste bin, the valve is arranged so that the valve plate can be displaced in the valve chamber from a first closed position to a second open position, in either a variable continuous movement or in steps.

I en foretrukket udførelsesform af den foreliggende opfindelse er ventilen indrettet således, at ventilpladen forskydes i en kontinuerlig bevægelse, hvilket medfører, at det affald, der ligger forrest i affaldsmagasinet i et kontrollabelt tempo løsnes og 25 efterfølgende transporteres væk, uden at der opstår en chokeffekt med en pludselig bevægelse af en stor mængde affald, der kan danne en prop i det efterfølgende rørsystem.In a preferred embodiment of the present invention, the valve is arranged such that the valve plate is displaced in a continuous motion, causing the waste located in the front of the waste bin to be loosened at a controllable rate and subsequently transported away without creating a shock effect. with a sudden movement of a large amount of debris that can form a plug in the subsequent piping system.

Det er vigtigt at kunne kontrollere åbningstiden af ventilpladen, fordi der er ulemper 30 forbundet med både en for hurtig åbning og en for langsom åbning.It is important to be able to control the opening time of the valve plate because there are drawbacks 30 associated with both a too fast opening and a too slow opening.

5 DK 175979 B15 DK 175979 B1

En for hurtig åbning af ventilpladen medfører en chokeffekt, hvor en stor mængde affald pludseligt bliver trukket igennem rørsystemet og derved kan danne en prop i det efterfølgende rørsystem.A too rapid opening of the valve plate results in a shock effect, where a large amount of waste is suddenly drawn through the pipe system and thereby can form a plug in the subsequent pipe system.

5 En for langsom åbning af ventilpladen medfører, at den primære transportluft har nået at bevæge så meget affald frem til ventilen, at den stopper til, og det derved ikke er muligt for den sekundære transportluft at løsne og accelerere affaldet videre i rørsystemet.5 Excessive opening of the valve plate causes the primary transport air to move so much waste to the valve that it stops, and thus it is not possible for the secondary transport air to loosen and accelerate the waste further in the pipe system.

10 En foretrukket åbne tid af ventilpladen er 2-5 sekunder.A preferred open time of the valve plate is 2-5 seconds.

For at undgå mekaniske problemer med ventilen i form af ophobning af affaldsmateriale i ventilkammeret og tæring af ventilpladen og ventilkammer er det vigtigt, at ventilen er selvrensende.In order to avoid mechanical problems with the valve in the form of accumulation of waste material in the valve chamber and corrosion of the valve plate and valve chamber, it is important that the valve is self-cleaning.

1515

Dette opnås ved, at ventilkammeret er udformet med et antal lufttilgange, som tillader, at der suges sekundær transportluft ind igennem ventilen.This is achieved by the valve chamber being designed with a number of air inlets which allow secondary transport air to be drawn in through the valve.

Denne sekundære transportluft har flere funktioner, for eksempel: 20 - når ventilpladen forskydes fra den første lukkede position, vil den sekundære transportlufi medføre en kraftig strømning omkring ventilpladen, således at den medriver affaldsmateriale, der er faldet ned imellem rørenderne og ned i ventilkammerets bund.This secondary transport air has several functions, for example: 20 - when the valve plate is displaced from the first closed position, the secondary transport air will cause a strong flow around the valve plate, so that it enters waste material which has fallen between the pipe ends and down into the bottom of the valve chamber.

25 - den sekundære transportluft vil løsne det affald, der ligger forrest i affaldsmagasinet.25 - the secondary transport air will release the waste that is at the front of the waste bin.

- den sekundære transportluft vil være medvirkende til, at det løse affald bliver 30 centreret i rørsystemet, accelereret og transporteret væk som "perler på en snor”.- the secondary transport air will contribute to the loose waste being centered in the piping system, accelerated and transported away as "beads on a string".

Den sekundære transportluft ledes igennem ventilen fra det øjeblik, hvor ventilpladen løftes og indtil ventilpladen er tilbage i en lukket position.The secondary transport air is passed through the valve from the moment the valve plate is lifted and until the valve plate is left in a closed position.

6 DK 175979 B16 DK 175979 B1

Da ventilen kan placeres på forskellige positioner i et afTaldssugeanlæg, hvor der er forskellige krav til mængden af sekundær transportluft, er det en fordel, hvis ventilens lufttilgang kan justeres. Derfor er nævnte lufttilgange udformet med et justerbart lukkearrangement.Since the valve can be placed in different positions in a Dust Suction System where there are different requirements for the amount of secondary transport air, it is an advantage if the air supply of the valve can be adjusted. Therefore, said air inlets are configured with an adjustable closing arrangement.

55

Dette bevirker, at det er muligt enten at indstille mængden af sekundær transportluft én gang før anvendelse af ventilen eller løbende justere mængden af sekundær transportluft under brugen af ventilen.This means that it is possible to either adjust the amount of secondary transport air once before using the valve or continuously adjust the amount of secondary transport air during use of the valve.

10 Typisk vil det være således, at ventilen bliver kalibreret, hvorved den nøjagtige mængde af sekundær transportluft bestemmes, og lukkearrangementet indstilles.Typically, it will be such that the valve is calibrated, thereby determining the exact amount of secondary conveying air and setting the closing arrangement.

Lukkearrangementet kan være en hvilken som helst form for afspærringsventil, hvor det er muligt at indstille afspærringsventilen i bestemte positioner for derved at tillade 15 forskellige mængder sekundær transportluft at trænge igennem ventilen.The closing arrangement can be any kind of shut-off valve, where it is possible to set the shut-off valve in certain positions, thereby allowing 15 different quantities of secondary transport air to pass through the valve.

I et affaldssugeanlæg med et manuelt betjent iukkearrangementet bestemmes mængden af nødvendig sekundær transportluft én gang og indstilles derefter. Denne metode kan anvendes for afTaldssugeanlæg, hvor der sjældent forekommer justering af 20 lukkearrangementet udover ved vedligehold/eftersyn af ventilen.In a waste suction system with a manually operated closing arrangement, the amount of secondary transport air needed is determined once and then adjusted. This method can be used for Drainage suction systems, where adjustment of the 20 closing arrangement is rare except for maintenance / inspection of the valve.

Anvendes lukkearrangementet i et afTaldssugeanlæg, hvor mængden af nødvendig sekundær transportluft justeres løbende, er nævnte justerbare lukkearrangement tilkoblet en styring, som kan aktivere og styre lukkearrangementet efter de aktuelle 25 forhold.If the closing arrangement is used in a waste suction system where the amount of required secondary transport air is continuously adjusted, said adjustable closing arrangement is connected to a control which can activate and control the closing arrangement according to the current conditions.

Denne styring kan være: - tilkoblet en ventilstyring, som styrer ventilpladen således, at mængden af sekundær 30 transportluft tilpasses ventilpladens åbningstid samt tilsætningstidspunktet, 7 DK 175979 B1 - en separat styring, der eksempelvis er tilkoblet en hovedstyring, hvorved mængden af sekundær transportluft til ventilen kan kontrolleres og eksempelvis tilpasses mængden af primærtransportlufi eller kraften af sugevakuumet, eller 5 - være en kombination af de to ovenstående muligheder.This control can be: - switched on a valve control which controls the valve plate so that the amount of secondary transport air is adjusted to the opening time of the valve plate and the time of addition, a separate control, for example connected to a main control, whereby the amount of secondary transport air to the valve can be controlled and, for example, adjusted to the amount of primary transport air or the power of the suction vacuum, or 5 - be a combination of the two options above.

Styringen kan være centralt placeret i et kontrolrum, hvilket medfører, at det ikke nødvendigt fysik at tilgå lukkearrangementet for at justere mængden af sekundær transportluft.The control can be centrally located in a control room, which means that there is no need for physics to access the closing arrangement to adjust the amount of secondary transport air.

1010

For at få størst nytteeffekt af den sekundære transportluft igennem ventilen er det vigtigt, at den sekundære transportluft ledes igennem ventilen, således at den er i medløb med den primære transportluft.To get the most benefit from the secondary transport air through the valve, it is important that the secondary transport air is passed through the valve so that it coincides with the primary transport air.

15 Det medfører, at nævnte lufttilgange er placeret på en side af nævnte ventilkammer, som i praksis er den side, der vender hen imod affaldsmagasinet.As a result, said air inlets are located on one side of said valve chamber, which is in practice the side facing the waste bin.

Lufttilgangen kan dog være monteret ovenpå eller på siden af ventilkammeret. Hvis nævnte lufttilgange er placeret på en side af nævnte ventilkammer, vil det være 20 umuligt at vende ventilen forkert, da det tydeligt vil fremgå af montagevej ledningen, at den sekundære transportluft skal tilføres den primære transportluft i medløb.However, the air inlet may be mounted on top or side of the valve chamber. If said air inlet is located on one side of said valve chamber, it will be impossible to turn the valve incorrectly, as it will be clear from the mounting path line that the secondary conveying air must be supplied to the primary conveying air in conjunction.

Tidligere er der anvendt ventilplader af rustfrit stål eller andre modstandsdygtige metallegeringer, der eventuelt har været forsynet med en plastforhudning, men 25 erfaringer har vist, at slid på ventilpladen har medført, at forhudningen slides væk, og at det aggressive miljø, som opstår på grund af affaldet, der er en blanding af almindeligt husholdningsaffald, alligevel vil forårsage tæring af en ventilplade af rustfrit stål eller anden metallegering.Previously, stainless steel valve plates or other resistant metal alloys have been used, which may have been fitted with a plastic foreskin, but 25 experiences have shown that wear of the valve plate has caused the foreskin to wear away and the aggressive environment caused by of the waste, which is a mixture of ordinary household waste, will nevertheless cause corrosion of a stainless steel valve plate or other metal alloy.

30 Derfor er nævnte ventiiplade udformet i et plastmateriale, som er hårdt, og som kan modstå det aggressive miljø, eksempelvis polycarbonat. For at opnå en tilstrækkelig styrke af ventilpladen vil det derfor være nødvendigt at fremstille den i en større tykkelse end en ventilplade af metal.Therefore, said valve plate is formed in a hard plastic material which can withstand the aggressive environment, for example polycarbonate. Therefore, in order to obtain a sufficient strength of the valve plate, it will be necessary to produce it in a greater thickness than a metal valve plate.

8 DK 175979 B18 DK 175979 B1

Det medfører, at mellemrummet mellem rørenderne i ventilkammeret skal være større.This means that the space between the pipe ends in the valve chamber must be larger.

Dette er dog ingen ulempe, da der dermed er større sandsynlighed for, at den sekundære transportlufi, der ledes ned omkring ventilpladen, bedre vil kunne medrive eventuelt ophobet affaldsmateriale og væsker, der er kommet ned i ventilkammerets 5 bund.This is not a disadvantage, however, since it is more likely that the secondary conveying air that is led down around the valve plate will be better able to trap any accumulated waste material and liquids that have come down into the bottom of the valve chamber 5.

I en udførelsesform af opfindelsen er nævnte ventil kammer udformet med tilgangsstudser for nævnte rørender, således at rørenderne tilkobles udvendigt på ventilen i stedet for indvendigt i ventilen.In one embodiment of the invention, said valve chamber is configured with access studs for said pipe ends so that the pipe ends are connected externally to the valve instead of internally of the valve.

10 På den måde sikres det, at ventilpladen lukker helt tæt i den første lukkede position, da ventilen indvendigt er opbygget således, at rørenderne passer nøjagtigt med ventilpladens tykkelse.In this way, it is ensured that the valve plate closes completely tightly in the first closed position, since the valve is internally constructed so that the pipe ends fit exactly with the thickness of the valve plate.

15 I et moderne affaldsindsamlingssystem er et affaldssugeanlæg i eksempelvis en boligblok opbygget således, at affaldet smides i affåldsskakte eller indkast, hvorunder der er placeret et affaldsmagasin, som kan opbevare affaldet, indtil affaldsmagasinet tømmes.15 In a modern waste collection system, a waste suction system in, for example, a housing block is constructed such that the waste is thrown into a waste shaft or thrown under which is placed a waste bin which can store the waste until the waste bin is emptied.

20 For at fa ventilerne i affaldssugeanlægget til at fungere optimalt er nævnte ventil placeret i nævnte rørsystem, således at den sekundære transportluft igennem nævnte lufttilgang er i medløb med en primær transportluft igennem nævnte rørsystem.In order to get the valves of the waste suction system to function optimally, said valve is located in said pipe system, so that the secondary transport air through said air supply is in conjunction with a primary transport air through said pipe system.

Det betyder, at den sekundære transportluft medvirker til at løsne affaldet i 25 affaldsmagasinet og accelerere affaldet, og samtidig sørger den for, at ventilen er selvrensende, idet ophobet affaldsmateriale i ventilkammeret medrives væk fra affaldsmagasinet.This means that the secondary transport air helps to loosen the waste in the waste bin and accelerate the waste, while at the same time ensuring that the valve is self-cleaning, as accumulated waste material in the valve chamber is carried away from the waste bin.

Er ventilen selvrensende, vil det betyde lavere omkostninger til vedligeholdelse af 30 ventilen, og affaldssugeanlæggets effektivitet vil øges.If the valve is self-cleaning, it will mean lower maintenance costs for the valve and the efficiency of the waste suction system will increase.

i i 9 DK 175979 B1 I en udførelsesform af opfindelsen er nævnte ventil placeret i nævnte rørsystem umiddelbart efter en affaldsskakt eller et affaldsmagasin, hvor ventilen anvendes som en afspæningsventil, der holder affaldet tilbage i affaldsmagasinet 5 For at løsne, accelerere og transportere affaldet væk fra affaldsmagasinet skal der anvendes en primær transportluft igennem rørsystemet sammen med en mængde sekundær transportluft igennem ventilen.In an embodiment of the invention, said valve is located in said piping system immediately after a waste shaft or waste magazine, wherein the valve is used as a tension valve holding the waste back in the waste bin 5 To loosen, accelerate and transport the waste away from the waste bin. a primary transport air through the pipe system must be used together with a quantity of secondary transport air through the valve.

I en anden udførelsesform af opfindelsen er nævnte ventil placeret i nævnte rørsystem 10 med en afstand til en affaldsskakt eller et affaldsmagasin, hvor ventilen anvendes som en sektionsventil, der holder dele af affaldssugeanlæggets rørsystem afspærret.In another embodiment of the invention, said valve is located in said piping system 10 at a distance from a waste shaft or waste bin, wherein the valve is used as a sectional valve holding parts of the waste suction system's piping system shut off.

Det anvendes typisk, hvis affaldssugeanlægget har en vis størrelse, hvor det ikke er muligt at sætte hele rørsystemet under vakuum på én gang.It is typically used if the waste suction system is of a certain size where it is not possible to put the entire pipe system under vacuum at one time.

1515

For at holde gang i transporteringen af affaldet væk ffa en sektion af rørsystemet skal der anvendes primær transportluft, samt en mængde eller ingen sekundær transportluft igennem ventilen.In order to keep the waste transport away from a section of the piping system, primary transport air must be used, as well as an amount or no secondary transport air through the valve.

20 Da ventilen er udformet således, at åbningen mellem rørenderne svarer til ventilpladens tykkelse, vil ventilen kunne være placeret i nævnte rørsystem i en vinkelposition, hvilket vil medføre, at ventilen kan placeres på lodrette rør, på rør med stigning eller på vandrette rør, uden at det går ud over ventilens funktionalitet.Since the valve is designed such that the opening between the pipe ends corresponds to the thickness of the valve plate, the valve may be located in said pipe system at an angular position, which will allow the valve to be placed on vertical pipes, on pipes with pitch or on horizontal pipes, without that it goes beyond the functionality of the valve.

25 I den foretrukne udførelsesform af opfindelsen anvendes ventilen som en afspærringsventil i et affaldssugeanlæg, og en tømning af et affaldsmagasin foregår efter følgende trin: a) der dannes et vakuum i nævnte rørsystem, som er placeret på en sugeside af 30 nævnte ventil, b) nævnte ventil åbnes ved at nævnte ventilplade løftes i en kontinuerlig bevægelse, 10 DK 175979 B1 c) der ledes sekundær transportluft igennem en sprække ved nævnte ventilplade, d) der ledes umiddelbart derefter primær transportluft igennem en affaldsmasse, således at den bringes frem til ventil og videre ud i nævnte rørsystem, 5 e) nævnte ventil lukkes ved at nævnte ventilplade sænkes, og f) der lukkes først for den primære transportluft, og umiddelbart derefter lukkes der for den sekundære transportluft.In the preferred embodiment of the invention, the valve is used as a shut-off valve in a waste suction system, and an emptying of a waste magazine takes place according to the following steps: a) a vacuum is formed in said pipe system located on a suction side of said valve; b) said valve is opened by said valve plate being lifted in a continuous motion; c) secondary transport air is passed through a crack at said valve plate; d) immediately thereafter primary transport air is passed through a waste mass so that it is brought to the valve and e) said valve is closed by lowering said valve plate, and f) is closed first for the primary transport air, and immediately thereafter for the secondary transport air.

10 1 de øjeblikke, hvor ventilpladen løftes op fra og senere sænkes ned i den lukkede position, er der en kraftig strømning af sekundær transportluft omkring ventilpladen, hvorved eventuel ophobet affaldsmateriale i ventilkammeret medrives og fjernes med blandingen af den primære og sekundære transportluft.In the moments when the valve plate is lifted from and later lowered into the closed position, there is a strong flow of secondary transport air around the valve plate, whereby any accumulated waste material in the valve chamber is entrained and removed with the mixture of the primary and secondary transport air.
