Description

selen, i det tilfelle vann skulle renne ut fra maskinen. the seal, in the event that water should flow out of the machine.

En enkel og billig ventil som oppfyller disse krav har de i hovedkravet angitte karakteristiske trekk. A simple and cheap valve that meets these requirements has the characteristic features specified in the main requirement.

Utlosningen av ventilen skjer fortrinnsvis ved at et elektrisk signal tilfores en elektrisk glodestift. Utlosningssignalet til ventilen behover imidlertid ikke å være elektrisk, men kan også være et trykksignal. The release of the valve preferably takes place by an electric signal being supplied to an electric glow plug. However, the release signal for the valve does not need to be electrical, but can also be a pressure signal.

Ytterligere fordeler og egenskaper ved oppfinnelsen fremgår av den efterfolgende beskrivelse av et utforelseseksempel under henvisning til tegningen, som viser et snitt gjennom en kombi-nert sikkerhets-, tilbakeslags- og strupeventil beregnet på å monteres i vanntilforselsledningen for en husholdningsmaskin. Further advantages and characteristics of the invention appear from the following description of an embodiment with reference to the drawing, which shows a section through a combined safety, non-return and throttle valve intended to be mounted in the water supply line for a household machine.

Et ventilhus er forsynt med en forste tilkobling 3 og en annen tilkobling 5,ved hjelp av hvilke ventilen kan innkobles i vann-tilf orselsledningen for en husholdningsmaskin, for eksempel en oppvaskmaskin. Ventilhuset har et sete 7 mot hvilket en ventil-konus 9 i den på tegningen viste stilling tetter ved at en ventilsats 11 er innskrudd i huset 1. En O-ringtetning 13 hindrer væskelekkasje i gjengeforbindelsen mellom innsatsen 11 og ventilhuset 1. Innsatsen 11 låses i justert stilling ved hjelp av en låsemutter 15. A valve housing is provided with a first connection 3 and a second connection 5, by means of which the valve can be connected to the water supply line for a household machine, for example a dishwasher. The valve housing has a seat 7 against which a valve cone 9 in the position shown in the drawing seals by a valve insert 11 being screwed into the housing 1. An O-ring seal 13 prevents liquid leakage in the threaded connection between the insert 11 and the valve housing 1. The insert 11 is locked in adjusted position using a lock nut 15.

Ventilkonusen 9 har en sentral åpning 17 og danner innvendig The valve cone 9 has a central opening 17 and forms an interior

sete 19 for et tallerkenventilelement 21. Dette ventilelement har en ventilspindel 23 som styres i en boring 25 i et sylind-risk stempel 27. Mellom boringens 25 bunn og spindelens 23 seat 19 for a poppet valve element 21. This valve element has a valve spindle 23 which is controlled in a bore 25 in a cylindrical piston 27. Between the bottom of the bore 25 and the spindle 23

ende er innspent en trykkfjær 29. end a compression spring 29 is clamped.

Stempelet 27 er under stor friksjon forskyvbart i ventilkonusens 9 hylseformede forlengelse 31. Eventuelt kan en O-ring 33 være innlagt mellom stempelet og hylsen. Hylsen kan forskyves i en boring 35 i ventilinnsatsen 11. En O-ringtetning 37 kan eventuelt være innlagt mellom hylsen 31 og innsatsen il. Hvis stempelet 27 og hylsen 31 er utfort av passende materiale, for eksempel teflon, oppnås glidbarhet under tetning uten behov for O-ringer. The piston 27 is displaceable under great friction in the sleeve-shaped extension 31 of the valve cone 9. Optionally, an O-ring 33 can be inserted between the piston and the sleeve. The sleeve can be displaced in a bore 35 in the valve insert 11. An O-ring seal 37 can optionally be inserted between the sleeve 31 and the insert 11. If the piston 27 and the sleeve 31 are lined with a suitable material, for example Teflon, sliding is achieved during sealing without the need for O-rings.

Ventilinnsatsens 11 ytre ende er forsynt med en boring 39 hvis ytre parti 41 er gjenget og har storre diameter slik at det dan-nes en avsats 43. Denne avsats 43 danner sete for en eksplosiv ladning, for eksempel en tennhette 45 eller lignende. I det gjengede parti 41 er innskrudd en glodestift 47 som er beregnet for lavspent stromtilforsel. The outer end of the valve insert 11 is provided with a bore 39 whose outer part 41 is threaded and has a larger diameter so that a ledge 43 is formed. This ledge 43 forms a seat for an explosive charge, for example an ignition cap 45 or the like. In the threaded part 41 is screwed a glow plug 47 which is intended for low-voltage power supply.

I foreliggende utforelseseksempel kan glodestiften for eksempel være innkoblet i en strbmkrets som inneholder et batteri og en fuktighetsdetektor som normalt holder kretsen åpen. Fuktighetsdetektoren er anbragt under husholdningsmaskinen og ved feil på denne som medforer at vann strdmmer ut, av-soker detektoren vannet og slutter strdmkretsen hvorved glodestiften opphetes. In the present embodiment example, the glow plug can, for example, be connected to a power circuit that contains a battery and a humidity detector that normally keeps the circuit open. The humidity detector is placed under the household appliance and in the event of a fault with this which causes water to flow out, the detector detects the water and closes the current circuit, whereby the glow plug is heated.

Den viste ventil har to innkoblingsmuligheter. Om tilkoblingen 3 forbindes med vanntilforselen og tilkoblingen 5 forbindes med husholdningsmaskinen, arbeider ventilen som en tilbakeslagsventil. Om derimot tilkoblingen 5 forbindes med vanntilforselen og tilkoblingen 3 forbindes med husholdningsmaskinen, arbeider ventilen som en innstillbar strupeventil. I begge tilfelle kan imidlertid sikkerhetsventilfunksjonen utnyttes. The valve shown has two connection options. If connection 3 is connected to the water supply and connection 5 is connected to the household appliance, the valve works as a non-return valve. If, on the other hand, connection 5 is connected to the water supply and connection 3 is connected to the household appliance, the valve works as an adjustable throttle valve. In both cases, however, the safety valve function can be utilized.

Innkobling som tilbakeslagsventil: Connection as non-return valve:

Vann strommer inn gjennom tilkoblingen 3 og trykker mot fjærens 29 virkning ventilelementet 21 oppover i stempelet 27 slik at åpningene 49, 51 i ventilhylsen 31 resp. innsatsen 11 frilegges og tillater at vann strommer til tilkoblingen 5. Hvis trykket av en eller annen grunn skulle oke ved tilkoblingen 5 og bli hoyere enn ved tilkoblingen 3, vil ventillegemet 21 av fjærens 29 kraft trykkes mot ventilsetet 19 og derpå også av vanntrykket på ventilelementets 21 overside holdes tettende mot setet 19. Tilbakestromning hindres således. Water flows in through the connection 3 and presses against the action of the spring 29 the valve element 21 upwards in the piston 27 so that the openings 49, 51 in the valve sleeve 31 resp. the insert 11 is exposed and allows water to flow to the connection 5. If for some reason the pressure should increase at the connection 5 and become higher than at the connection 3, the valve body 21 will be pressed against the valve seat 19 by the force of the spring 29 and then also by the water pressure on the valve element 21 upper side is kept tightly against the seat 19. Backflow is thus prevented.

Om fuktighetsdetektoren avgir et signal, vil glodestiften 47 oppvarmes og tennhetten 45 detonnerer. I det av boringen 39 dannede detonnasjonskammer oppstår derved et gasstrykk som på-virker stempelets 27 overside og trykker dette nedover. If the humidity detector emits a signal, the glow plug 47 will heat up and the ignition cap 45 will detonate. In the detonation chamber formed by the bore 39, a gas pressure thereby arises which acts on the upper side of the piston 27 and presses it downwards.

Stempelets underside skyver ventilelementet 21 til anlegg mot setet 19. Friksjonskraften mellom stempelet 27 og hylsen 31 skal da være storre enn den maksimale kraft som vanntrykket i tilkoblingen 3 kan utove på ventilelementets 21 underside og som soker å lofte ventilelementet 21 opp igjen fra dets sete. Ventilen forblir således stengt. The underside of the piston pushes the valve element 21 into contact with the seat 19. The frictional force between the piston 27 and the sleeve 31 must then be greater than the maximum force that the water pressure in the connection 3 can exert on the underside of the valve element 21 and which seeks to lift the valve element 21 up again from its seat. The valve thus remains closed.

Efter at feilen på husholdningsmaskinen er utbedret, skrues innsatsen 11 ut ved hjelp av et på dens overside anbragt skruejerns-spor 53. Stempelet 27 presses igjen opp til sin overste stilling og innsatsen 11 innsettes igjen. Derefter loses glodestiften 47 og en ny tennhette 45 anbringes på plass. After the fault on the household appliance has been rectified, the insert 11 is unscrewed using a screwdriver slot 53 placed on its upper side. The piston 27 is again pressed up to its uppermost position and the insert 11 is inserted again. The glow plug 47 is then loosened and a new spark cap 45 is placed in place.

Innkobling som strupeventil; Connection as throttle valve;

Når ventilen skal arbeide som innstillbar strupeventil, forbindes tilkoblingen 5 med vanntilforselen, idet tilkoblingen 3 da forbindes med husholdningsventilen. Tilbakeslagsventilen er nu ute av funksjon da ventilelementet 21 holdes i stengt stilling av det hoyere trykk i tilkoblingen 5. Figuren viser ventilen i stengt stilling og regulering av strupefunksjonen fås ved bnsket oppskruing av innsatsen 11, hvorved ventilkonusen 9 slipper ventilsetet 7 og frilegger en således innstillbar strom-ningsspalte. When the valve is to work as an adjustable throttle valve, connection 5 is connected to the water supply, as connection 3 is then connected to the household valve. The non-return valve is now out of order as the valve element 21 is held in the closed position by the higher pressure in the connection 5. The figure shows the valve in the closed position and regulation of the throttle function is obtained by carefully unscrewing the insert 11, whereby the valve cone 9 releases the valve seat 7 and exposes a thus adjustable flow gap.

Hvis strom tilfores til glodestiften 47, vil som foran nevnt stempelet 27 bli presset nedad under gasstrykkets innvirkning. Derved medbringes hylsen 31 som beveger seg nedad inntil konu-sen 9 stoter mot ventilsetet 7 og ventilen dermed stenges. If current is supplied to the glow plug 47, as mentioned above, the piston 27 will be pressed downwards under the influence of the gas pressure. Thereby, the sleeve 31 is brought along, which moves downwards until the cone 9 hits the valve seat 7 and the valve is thus closed.

Tilbakestilling av ventilen skjer som ovenfor nevnt ved at innsatsen 11 skrus inn og stempelet 27 samt nu også hylsen 31 skyves opp til sine opprinnelige stillinger. Resetting the valve takes place as mentioned above by screwing the insert 11 in and the piston 27 and now also the sleeve 31 are pushed up to their original positions.

Om det onskes, kan en kanal 55 med lite gjennomstrømningsareal fore fra boringen 39 eller boringen 35 til innsatsens 11 ytre. Gasstrykket kan langsomt stromme ut gjennom denne kanal, slik at intet resttrykk blir stående igjen i ventilen, hvilket ville kunne vanskeliggjøre gjeninnstilling til utgangsstilling. Ka-nalens 55 utmunning på innsatsens 11 utside kan være lukket med en farveflekk 57 eller lignende som blåses bort ved gassens ut-stromning. Derved fås en optisk indikasjon for at sikkerhets-ventilen er utlost. If desired, a channel 55 with a small flow area can lead from the bore 39 or the bore 35 to the outside of the insert 11. The gas pressure can slowly flow out through this channel, so that no residual pressure is left in the valve, which could make it difficult to reset to the initial position. The opening of the channel 55 on the outside of the insert 11 can be closed with a color spot 57 or the like which is blown away by the outflow of the gas. This provides an optical indication that the safety valve has been released.

Hvis tilbakeslagsventilfunksjonen ikke fordres kan ventilen ifolge oppfinnelsen utformes enklere ved at tallerkenventil-elementet 21 sloyfes og den ifolge utforelseseksemplet som hylse 31 utforte forlengelse av ventilkonusen 9 i stedet ut-fores massiv. Dette massive legeme er under gasstrykket ved utlosning av ventilen forskyvbart i boringen 35 slik at ventilkonusen 9 lukker mot ventilsetet 7. If the non-return valve function is not required, the valve according to the invention can be designed more simply in that the poppet valve element 21 is flattened and, according to the embodiment example, the sleeve 31 formed as an extension of the valve cone 9 is instead formed solid. This massive body is displaceable under the gas pressure when the valve is released in the bore 35 so that the valve cone 9 closes against the valve seat 7.

En ventil ifolge oppfinnelsen kan også anvendes for ved utlosning å åpne gjennornstromningsveien 3-5, f.eks. til et sprinkleran-legg. Setet er da normalt tillukket med en tetningsskive mens ventilelementets spiss 9 er gjennomboret 17 eller riflet. A valve according to the invention can also be used to open the return flow path 3-5 when released, e.g. to a sprinkler system. The seat is then normally closed with a sealing disc while the tip 9 of the valve element is pierced 17 or knurled.

Ved utlosning slår da ventilelementets konusspiss 9 bort skiven og tillater stromning gjennom setet. When released, the cone tip 9 of the valve element knocks the disc away and allows flow through the seat.

Som alternativ til den eksplosive ladning i det ovenfor beskrev-ne utforelseseksempel er det mulig å anvende to eller flere stoffer, som foranlediger eksplosjonslignende gassutvikling når de kommer i beroring med hverandre. As an alternative to the explosive charge in the embodiment example described above, it is possible to use two or more substances, which cause explosion-like gas development when they come into contact with each other.
