DK 152451 BDK 152451 B

Opfindelsen angår et luftskrankeelement med et bærelegeme for en stråledyse, der over en kanal i bærelegemet kan sluttes til en fødeledning, samt for en i afstand fra stråledysen anbragt fangdyse, som er indrettet til at opfange den fra stråledysen afgivne luftstråle, 5 der derefter via en anden kanal i bærelegemet føres til en signalledning.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an air counter element having a carrier for a jet nozzle which can be connected to a feed line over a channel in the carrier, and to a catch nozzle located at a distance from the jet nozzle which is adapted to intercept the air jet emitted from the jet nozzle. a second channel in the carrier is routed to a signal line.

Luftskrankeelementer af denne art anvendes f.eks. til detektering af forekomst af forstyrrende fremmedlegemer ved et overvågningssted, f.eks. i et af begrænsningsvægge omgivet rum.Air counter elements of this kind are used e.g. for detecting the occurrence of disruptive foreign matter at a monitoring site, e.g. in a space enclosed by restriction walls.

10 Kendte luftskrankeelementer af denne art har den ulempe, at fastgørelsen af bærelegemet på monteringsstedet er forholdsvis kompliceret og kræver forholdsvis stor plads, idet der til fastgørelsen sædvanligvis anvendes særlige bøjler eller konsoller, der sammen med hele lufts krankeelementet og dettes bærelegeme skal anbringes på 15 overvågningsstedet, der kan være vanskeligt tilgængeligt, og hvor pladsforholdene desuden ofte er stærkt begrænsede. De særlige bøjler eller konsoller fordyrer desuden fremstillingen.Known air counter elements of this kind have the disadvantage that the attachment of the support body to the mounting site is relatively complicated and requires relatively large space, since special attachment brackets or brackets are usually used for the attachment, which together with the entire air counter element and its support body must be placed at the monitoring site. that can be difficult to access and where space conditions are often severely restricted. The special hangers or brackets also make manufacturing more expensive.

Formålet med opfindelsen er at tilvejebringe et luftskrankeelement, som foruden at være af særlig enkel og kompakt konstruktion 20 nemt kan anbringes på en sådan måde, at kun selve dyselegemet optager plads på overvågningsstedet, d.v.s. i rummet, der skal overvåges, og ved hvilket der ikke skal anvendes fordyrende særlige bøjler eller konsoller til fastgørelsen.The object of the invention is to provide an air counter element which, in addition to being of particularly simple and compact construction 20, can easily be arranged in such a way that only the nozzle body itself occupies space at the monitoring site, i.e. in the room to be monitored and at which no costly special hangers or brackets are to be used for fastening.

Denne opgave løses ifølge opfindelsen ved, at bærelegemet 25 består af et dyselegeme, der indeholder stråledysen og fangdysen, samt af en med dyselegemet koaksial monteringsdel, der er fast forbundet med dyselegemet ved dettes mod fødeluftledningen og signalledningen vendende side, og at monteringsdelen har et udvendigt gevind med tilhørende monteringsmøtrikker, der på i og for sig kendt 30 måde kan skrues i retning mod hinanden og bort fra hinanden. Ved denne udformning opnås den fordel, at luftskrankeelementet har en aflang form, hvor dyselegemet danner en yderste endedel af luftskrankeelementet og sidder koaksialt i forlængelse af monteringsdelen, der ved sin modsatte ende er sluttet til henholdsvis fødeluftledningen og 35 signalledningen. Derved kan luftskrankeelement nemt indføres gennem en udsparing i en begrænsningsvæg til et rum, der skal overvåges, og ved hjælp af monteringsdelen og de tilhørende monteringsmøtrikker, der spændes mod væggen fra hver sin side af denne, er det muligt at montere luftskrankeelementet på en sådan mide, at kun 2This object is solved according to the invention in that the support body 25 consists of a nozzle body containing the jet nozzle and the catch nozzle, as well as a coaxial mounting member with the nozzle body, which is firmly connected to the nozzle body at its side facing the feed air line and the signal line, and that the mounting part has an outside threads with associated mounting nuts, which in a manner known per se can be screwed in a direction towards each other and away from each other. In this embodiment, the advantage is obtained that the air counter element has an elongated shape, in which the nozzle body forms an outer end portion of the air counter element and sits coaxially in extension of the mounting part, which at its opposite end is connected to the feed air line and the signal line respectively. In this way, the air counter element can be easily inserted through a recess in a restriction wall to a room to be monitored, and by means of the mounting part and the associated mounting nuts, which are tensioned against the wall from each side thereof, it is possible to mount the air counter element on such a mite , that only 2

dyselegemet, der danner den egentlige detekteringsdel, befinder sig på overvågningsstedet i rummet, der skal overvåges, medens monteringsdelen med tilsluttet fødeluftledning og signalledning befinder sig uden for på den anden side af rummets begrænsningsvæg.the nozzle body which forms the actual detection portion is at the monitoring site in the room to be monitored, while the mounting portion with connected feed air line and signal line is outside of the confining wall of the room.

5 En foretrukken udførelsesform for luftskrankeelementet ifølge opfindelsen er ejendommelig ved, at dyselegemet har form som et C, hvis ene C-gren, der er beliggende ved den sideaf dyselegemet, ved hvilken monteringsdelen er fast forbundet med dyselegemet, indeholder fangdysen, og hvis anden dermed parallelle gren indehol-10 der stråledysen, og at fangdysen og stråledysen er anbragt aksialt flugtende med deres mundinger direkte over for hinanden. Herved opnås den fordel, at dyselegemet på grund af den aksialt flugtende anbringelse af striledysen og fangdysen i modsætning til hidtil kendte luftskrankeelementer kan udformes med så små dimensioner, at det set 15 i radial retning ikke rager ud over monteringsdelen, og således tillader at luftskrankeelementet også kan føres gennem udsparingen i væggen udefra.A preferred embodiment of the air counter element according to the invention is characterized in that the nozzle body is in the form of a C, whose C branch, located at the side of the nozzle body, at which the mounting part is fixedly connected to the nozzle body, contains the nozzle body and the other one parallel branch includes the jet nozzle and the catch nozzle and jet nozzle are axially flush with their orifices directly opposite each other. Hereby the advantage is obtained that the nozzle body, because of the axially flushing arrangement of the spray nozzle and the catch nozzle, unlike previously known air counter elements can be designed with such small dimensions that, seen in radial direction, it does not extend beyond the mounting part, and thus allow the air counter element also can be passed through the recess in the wall from the outside.

Ifølge yderligere en foretrukken udførelsesform for luftskrankeelementet er der på monteringsdelens modsat dyselegemet 20 beliggende endeflade anbragt aksialt rettede tilslutningsstudse for fødeluftledningen og signalledningen. Herved opnås, at luftskrankeelementets pladsbehov i radial retning ikke forøges på grund af disse to ledninger.According to a further preferred embodiment of the air counter element, the end surface of the mounting member opposite to the nozzle body 20 is provided with axially directed connecting studs for the feed air line and the signal line. In this way, the space requirement of the air counter element in the radial direction is not increased because of these two wires.

I det følgende forklares opfindelsen nærmere under henvis-25 ning til tegningen. På tegningen viser:The invention will now be explained in more detail with reference to the drawings. In the drawing:

Fig. 1 et lufts krankeelement ifølge opfindelsen set fra siden, fig. 2 det i fig. 1 viste lufts krankeelement set i pilretningen II i fig. 1, og 30 fig. 3 det i fig. 1 og 2 viste luftskrankeelement set i pilretningen III i fig. 1.FIG. 1 is a side view of an air faucet element according to the invention; FIG. 2 shows the embodiment of FIG. 1 in the direction of arrow II in FIG. 1, and FIG. 3 shows the embodiment of FIG. 1 and 2, seen in the direction of arrow III in FIG. First

Det i fig. 1 viste lufts krankeelement udgøres af et bærelegeme 1 med et dyselegeme 2 og en med dyselegemet 2 koaksial monteringsdel 3. Dyselegemet 2 indeholder en stråledyse 4 og en fangdyse 35 5, der er indrettet til, når der ikke forekommer forstyrrende frem medlegemer mellem denne og stråledysen 4, at opfange en fra stråledysen afgiven luftstråle, der over en kanal 6 i bærelegemet føres til en signalledning 7. Striledysen 4 er over en kanal 10 forbundet med en fødeluftledning 11. Dersom der i rummet 8 mellem striledysen 4 og 3The FIG. 1, the crank element shown in Fig. 1 is constituted by a support body 1 with a nozzle body 2 and a coaxial mounting part 3 with the nozzle body 2. The nozzle body 2 contains a jet nozzle 4 and a nozzle 35 5, which is adapted for when no disturbing forward bodies exist between it and the jet nozzle. 4, to capture an air jet emitted from the jet nozzle which is passed over a channel 6 in the carrier to a signal line 7. The jet nozzle 4 is connected over a channel 10 to a feed air line 11. If in the space 8 between the jet nozzle 4 and 3

DK 152451 BDK 152451 B

fangdysen 5 optræder forstyrrende fremmedlegemer, vil strålen fra stråledysen 4 til fangdysen 5 og dermed som et tegn på forekomsten af sådanne forstyrrende fremmedlegemer også luftstrømmen til signalledningen 7 blive afbrudt. Luftskrankeelementer af denne art anven-5 des til at konstatere tilstedeværelsen af fremmedlegemer i et overvåget rum.when the nozzle 5 occurs, interfering with foreign bodies, the jet from the jet nozzle 4 to the nozzle 5 and thus as a sign of the occurrence of such disturbing foreign bodies, the air flow to the signal line 7 will also be interrupted. Air counter elements of this kind are used to detect the presence of foreign matter in a monitored room.

I den viste udførelsesform har monteringsdelen 3, som det bedst ses i fig. 3, et cirkelrundt tværsnit. Det ud i et stykke med monteringsdelen 3 udformede dyselegeme 2 har to modstående flade 10 sider 16a, 16b og har set fra siden form som et C, hvis ene C-gren 12, der er beliggende ved den side af dyselegemet 2, ved hvilken dette er fast forbundet med monteringsdelen 3, indeholder fangdysen, og hvis anden dermed parallelle C-gren 14 indeholder stråledysen 4. Fangdysen 5 og stråledysen 4 er som vist anbragte aksialt flugtende 15 med deres mundinger direkte over for hinanden. Fangdysen 5 har en større diameter end stråledysen 4. Den fra fangdysen 5 til signalledningen 7 førende kanal 6 strækker sig gennem dyselegemet 2's med monteringsdelen 3 forbundne C-gren 12 og videre gennem monteringsdelen og en tilslutningsstuds 27 til tilslutning af signalledningen 7.In the illustrated embodiment, the mounting member 3, as best seen in FIG. 3, a circular cross section. The nozzle body 2 formed integrally with the mounting member 3 has two opposite faces 10 sides 16a, 16b and has a side view as a C, one C branch 12, located at the side of the nozzle body 2, at which this is fixedly connected to the mounting portion 3, contains the trapping nozzle, and if the other parallel C branch 14 contains the jet nozzle 4. The trapping nozzle 5 and the jet nozzle 4 are disposed axially flush 15 with their mouths directly opposite each other. The nozzle 5 has a larger diameter than the jet nozzle 4. The channel 6 passing from the nozzle 5 to the signal line 7 extends through the nozzle body 2 of the C-branch 12 connected to the mounting member 3 and further through the mounting member and a connecting rod 27 to connect the signal line 7.

20 Kanalen 10, over hvilken stråledysen 4 er sluttet til fødeluftledningen 11, strækker sig gennem en tilslutningsstuds 28 til tilslutning af fødeluftledningen 11 og videre gennem monteringsdelen og det C-formede dyselegeme 2's forbindelsesstykke 15 mellem dets C-grene 12 og 14 og videre gennem dyselegemets C-gren 14, hvor den efter to vinkelbøj-25 ninger 17a,17b på hver ca. 90° ender i stråledysen 4. De to tilslutningsstudse 27 og 28 for henholdsvis signalledningen og fødeluftledningen rager parallelt ud fra den modsat dyselegemet vendende aksi-ale endeflade 26 af monteringsdelen 3 og kan hensigtsmæssigt til en lettere identifikation have forskellig form.The duct 10, over which the jet nozzle 4 is connected to the feed air conduit 11, extends through a connecting nozzle 28 to connect the feed air conduit 11 and further through the mounting member and the connecting piece 15 of the C-shaped nozzle body 2 between its C branches 12 and 14 and further through the nozzle body. C-branch 14, where after two angular bends 17a, 17b, each of approx. 90 ° ends in the jet nozzle 4. The two connecting pins 27 and 28 for the signal line and the feed air line, respectively, project parallel to the opposite end body 26 of the mounting portion 3 of the nozzle body and may conveniently have a different shape for easier identification.

30 I det viste udførelseseksempel er monteringsdelen 3 forsynet med to fastgørelsesmøtrikker 18,19, der på et udvendigt gevind på monteringsdelen 3 kan skrues i retning mod hinanden og bort fra hinanden. Ved monteringen af luftskrankeelementet stikkes dette gennem en åbning 22, f.eks. i en væg 21, der skal tjene som bære-35 væg eller underlag, hvorefter møtrikkerne 18 og 19 spændes mod hver sin side af væggen. Da monteringsdelens udvendige gevind strækker sig over hele længden af monteringsdelen, kan hele elementet uden videre ved indstilling af møtrikkerne 18,19 uden videre forskydes i dobbeltpilretningen 25 til opnåelse af den ønskede position af dyse- 4In the illustrated embodiment, the mounting member 3 is provided with two fastening nuts 18,19, which can be screwed in a direction towards one another and away from one another on an external thread of the mounting member 3. When mounting the air counter element, this is pierced through an opening 22, e.g. in a wall 21 to serve as a carrier or wall or substrate, after which the nuts 18 and 19 are tightened against each side of the wall. Since the external thread of the mounting member extends over the entire length of the mounting member, the entire element can be readily displaced in the double arrow direction 25 by adjusting the nuts 18,19 to obtain the desired position of the nozzle.

legemet 2. Eventuelt kan lufts krankeelementet også fastgøres til en bærevæg, ved at det holdes mod kanten af denne, hvorefter møtrikkerne fra hver sin side spændes mod væggen, således at elementet fastklemmes ved væggens kant. Monteringen af luftskrankeelementet kan således gennemføres på enkel måde, og justeringen kan udføres af ikke-uddannet personale.The body 2. Optionally, the air collar element can also be attached to a supporting wall by holding it against the edge thereof, after which the nuts from each side are clamped against the wall, so that the element is clamped at the edge of the wall. The mounting of the air counter element can thus be carried out in a simple manner and the adjustment can be carried out by unskilled personnel.
