Foderventil med indbygget lækagefoler.Feed valve with built-in leakage foils.

Frembringelsens anvendelsesområdeScope of production

Denne frembringelse angår cn foderventil med indbygget lækagefoler til anvendelse i automatiske fodringsanlæg indenfor landbrugssektoren.This production relates to a feed valve with built-in leakage foils for use in automatic feeding plants in the agricultural sector.

Kendt teknikPrior art

De i dag anvendte fodervenliler er næsten alle af typen membranventil. (Se fig. 1) hvor en gummimembran holder ventilen lukket ved hjælp aftrykluft.The feed valve lilies used today are almost all of the membrane valve type. (See Fig. 1) where a rubber diaphragm holds the valve closed by compressed air.

De har alle den ulempe at efterhånden som membranen slides vil denne på et tidspunkt revne, således at den til lukningen anvendte trykluft kan forplante sig ind i foderrorene, med deraf folgendc driftsforstyrrelser.They all have the disadvantage that as the diaphragm wears, it will tear at some point, so that the compressed air used for the closure can propagate into the feed tubes, with consequent operational interruptions.

Det tekniske problem tier skal losesThe technical problem should be solved

Det er et kendt problem, al når membranen i en niembranventil bliver utæt begynder det med et meget lille hul, og da hullet befinder sig inde i ventilen, kan den defekte ventil ikke lokaliseres på normal vis f.eks. ved anvendelse af akustisk lytteudstyr. For at tinde frem til den defekte ventil, skal disse imdersoges enkeltvis, hvilket sker ved at afbryde trykluftforsyningen til den enkelte ventil, og herefler kontrollere om forbruget af trykluft falder. Da et foderanlæg kan indeholde tiere hundrede ventiler er dette en meget lidskrævende procedure.It is a known problem, even when the diaphragm of a non-diaphragm valve becomes leaky, it begins with a very small hole, and since the hole is inside the valve, the defective valve cannot be located in a normal way e.g. using acoustic listening equipment. In order to detect the defective valve, these must be inspected individually, which is done by disconnecting the compressed air supply to the individual valve, and then checking whether the consumption of compressed air falls. Since a feed plant can contain tens of hundreds of valves, this is a very demanding procedure.

Med frembringelsen onskes en metode til automatisk detektering af defekte ventiler.With the generation, a method for automatically detecting defective valves is desired.

Den nye teknikThe new technique

Det nye ved frembringelsen hestår i at indhygge en automatisk lækagefoler i foderveulilen. Den tekniske virkningThe new thing about the production is that of an automatic leakage foil in the feed veil. The technical impact

Ved at indbygge en passende foler i foderventilen. vil denne i det tilfælde at en lækage konstateres sende et signal til foderanlæggets styreenhed. Da hver foderventil har sig eget entydige nummer, vil signalet indeholde information om hvilken ventil der er blevet utæt. og dette betyder at der spares megen tid på udbedring af fejlen.By incorporating a suitable leaflet into the feed valve. in the event of a leak being detected, this will send a signal to the feed unit control unit. Since each feed valve has its own unique number, the signal will contain information about which valve has been leaked. and this means saving a lot of time on fixing the error.

I fig. 2 er vist en metode hvor der anvendes en flowmåler (5) lil måling af den luftmængde der strømmer ind til membranen (!) gennem luftkanalen (6). Signalet fra flowmåleren (5) sendes til den indbyggede elektroniske forstærker (7). og i det tilfælde der konstateres el unormalt luftforbrug sendes signalet videre til foderanlæggets slyreenhed (10) via ledningen (9). samtidig indikeres fejlen med indikatorlainpen (8). Hver gang foderventilen åbner eller lukker opstår der en kortvarig luftstrøm i-luftkanalen (6) og ved at måle denne er det muligt at konstatere om foderventilen reagerer korrekt på styresignalet fra foderanlæggets styreenhed (10). Hvis der måles en konstant luftstrøm, er det tegn på en utæt membran.In FIG. 2 is a method of using a flow meter (5) for measuring the amount of air flowing into the diaphragm (!) Through the air duct (6). The signal from the flow meter (5) is sent to the built-in electronic amplifier (7). and in the case of abnormal air consumption, the signal is transmitted to the slurry unit (10) of the feed system via the line (9). at the same time, the error is indicated by the indicator lamp (8). Each time the feed valve opens or closes, a short-term air flow occurs in the in-air duct (6) and by measuring it it is possible to ascertain whether the feed valve responds correctly to the control signal from the feed unit control unit (10). If a constant flow of air is measured, it is a sign of a leaking membrane.

I t’ig. 3 er vist en metode hvor den elektriske ledningsevne inde i membranen måles. I det tilfælde der opstår en utæthed i membranen (1). vil der på grund af hårrorsvirkning kunne trænge fugt fra foderet i roret (3) ind (il et i membranen indlejret lag (II) der vil blive elektrisk ledende. Når dette sker lober signalet via forbindelsen (12) til den elektroniske forstærker (7) og herfra sendes signalet videre til styreenheden (10) samtidig med at fejlen indikeres på indikatorlampen (8).I did. 3 is a method of measuring the electrical conductivity inside the membrane. In the event of a leakage in the membrane (1). For example, due to hair shaking action, moisture from the feed may enter the tube (3) (into a layer (II) embedded in the membrane which will become electrically conductive. When this occurs, the signal runs through the connection (12) to the electronic amplifier (7) and from here the signal is passed to the control unit (10) while the error is indicated on the indicator lamp (8).

DK 2005 00119U3 I fig. 4 er vist en metode hvor der anvendes en trykl'oler. Når der skal laves en måling, afspærrer magnetventilen (I4) lufttilforslen til membranen (I). Hvis lufttrykket i kanalen (6) ændres når lufttilforslen afspærres. er del tegn på en utæt membran, og det ændrede lufttryk delekteres at trykfoleren (13) og den elektroniske forstærker (7) som sender signalet videre til toderanlæggets styreenhed (10) samtidig med at fejlen indikeres på indikatnrlampen (8).DK 2005 00119U3 In fig. 4 shows a method using a pressure gauge. When making a measurement, the solenoid valve (I4) shuts off the air supply to the diaphragm (I). If the air pressure in the duct (6) changes when the air supply is blocked. are part signs of a leaking membrane, and the altered air pressure is detected by the pressure sensor (13) and the electronic amplifier (7) which transmits the signal to the control unit (10) of the toddler system at the same time as the error is indicated on the indicator lamp (8).

I tig. 5 er vist en metode hvor der anvendes en mikrofon. Når luft passerer gennem en lille åbning under hojt tryk vil der genereres stoj i form af ultralyd. Ved at placere en mikrofon (16) i luftkanalen (6) er det muligt at detektere den fremkaldte stoj. Signalet fra mikrofonen (16) sendes til en elektronisk forstærker (7) som i tilfælde af en lækage sender signalet videre til foderanlæggets styreenhed (10) samtidig med at fejlen indikeres på indikatorlampen (8).I beg. 5 shows a method using a microphone. When air passes through a small orifice under high pressure, noise will be generated in the form of ultrasound. By placing a microphone (16) in the air duct (6) it is possible to detect the induced noise. The signal from the microphone (16) is sent to an electronic amplifier (7) which, in the event of a leak, transmits the signal to the control unit (10) of the feed system at the same time as the error is indicated on the indicator lamp (8).
