Abstract

Subject of the invention is a locking element, which provides the possibility of attaching a lateral branch pipe (30) to the main piping without the need for temporary interrupting the media flow through the main piping and thus reliable hydraulic link between the branch pipe (30), while if required such a hydraulic link can also be interrupted. For this purpose, enclosure (2) of the locking element (1) features a hinged sealing panel (4), which can be rotated around the rotating axis (40) with the help of a form-fitting link attached to a control element (5), which is always required as rotatable around the rotation axis (50). The panel (4) features an adequately large sealing area (41) for covering the opening in the wall of the main piping as well as a passage (42), which allows either access to a drilling tool of a drilling device up to the location provided for making a hole in the main piping or to establish a hydraulic link between the main piping and the branch pipe (30) after the application of the opening in the wall of the main piping

Description

Zaporni organ za izvedbo cevnega priključka na cevovoduThe shut-off body for the implementation of the pipe connection on the pipeline

Izum v okviru strojništva spada na področje cevovodov, še zlasti na področje izvedbe priključkov z navrtanjem stene cevi, v kateri se pretaka medij pod pritiskom. Po drugi strani je tovrstne izume v okviru vrtanja in podobnih obdelovalnih procesov mogoče uvrstiti tudi na področje pripomočkov za navrtanje cevovodov, v katerih se pretaka medij pod pritiskom.In the field of mechanical engineering, the invention relates to the field of pipelines, and in particular to the field of making connections by threading the wall of the pipe in which the medium under pressure flows. On the other hand, such inventions in the context of drilling and similar machining processes can also be classified in the field of pipeline drilling aids in which pressure medium flows.

Pri tem izum temelji na problemu, kako realizirati za izvedbo individualnega priključka predviden zaporni organ, še zlasti na cevi vodovoda za oskrbo s pitno vodo, ki naj bi omogočal priključitev individualnega stranskega priključnega voda na glavni cevovod na higieničen način brez vdiranja ostružkov v notranjost zapornega organa oz. cevovoda in še zlasti tudi brez potrebe po začasni prekinitvi pretakanja medija skozi glavni cevovod ter na ta način zanesljivo hidravlično povezavo med priključnim vodom in glavnim cevovodom, po potrebi pa tudi prekinitev te hidravlične povezave.The invention is based on the problem of how to realize the intended closure body for the implementation of the individual connection, especially on the pipes of the drinking water supply line, which is intended to enable the connection of the individual side connection line to the main pipeline in a hygienic manner without breaking the chips into the interior of the closure body. oz. pipeline, and in particular without the need to temporarily interrupt the flow of the medium through the main pipeline, thereby ensuring a reliable hydraulic connection between the connecting line and the main pipeline, and, if necessary, terminating that hydraulic connection.

Tovrstni zaporni organi, bodisi kot ventili ali zasuni, so splošno znani iz komercialne dokumentacije, nekaj tovrstnih rešitev pa je na voljo tudi v patentni literaturi. S problemom navrtanja glavne cevi, v kateri se med vrtanjem pretaka medij pod pritiskom, se ukvarja EP 0 024 741. Vendar pa se omenjena rešitev osredotoča izključno na problem učinkovitega odvajanja ostružkov, kar dosežejo s posebno izvedbo vrtalnega orodja. Prijavitelju so iz komercialne dokumentacije znane tudi druge rešitve (npr. iz prospektov nemškega proizvajalca hidravlične opreme BOPP & REUTHER GmbH). Tovrstni zaporni organi, t.j. zasuni ali ventili, so prirejeni za namestitev na glavni cevovod na mestu izvedbe želenega priključka in obsegajo ustrezno ohišje in pritrdilna sredstva, s pomočjo katerih je mogoče ohišje tesno prilegajoče se pritrditi na obod glavnega cevovoda. Na ohišje je mogoče po eni strani namestiti ustrezno vrtalno pripravo za navrtanje glavnega cevovoda, po drugi strani pa tudi pritrditi priključni vod, ki je predviden za vzpostavitev ustrezne hidravlične povezave med individualnim priključkom in omenjenim glavnim cevovodom. Nadalje je v ohišju na voljo zaporna plošča, ki obsega dovolj obsežno tesnilno območje in prehod za vrtalno orodje, s pomočjo katerega se na želenem mestu navrta steno glavnega cevovoda, v katerem se pretaka medij pod pritiskom, ne da bi bilo pri tem potrebno prekiniti pretoko skozi glavni cevovod. V ta namen je omenjena tesnilna plošča premakljiva v dva končna položaja. V prvem končnem položaju se tesnilno območje tesnilne plošče nahaja izven območja navrtanja glavnega cevovoda, prehod za vrtalno orodje pa se nahaja nad mestom navrtanja na zunanji površini stene glavnega cevovoda. V preostalem končnem položaju tesnilne plošče se tesnilno območje tesnilne plošče nahaja nad mestom navrtanja glavnega cevovoda, tesnilno območje tesnilne plošče pa je pomaknjeno vstran od mesta navrtanja. Premikanje omenjene drsne plošče iz enega v drug končni položaj poteka kot zasuk te drsne plošče okoli vrtišča za določen kot, ki v praksi znaša približno 45°. V ta namen je tesnilna plošča na obodu opremljena z ozobjem, s katerim sodeluje zobnik, kije vrtljivo uležiščen v ohišju. Po namestitvi ohišja na zunanji obod glavnega cevovoda, v katerem se pretaka medij pod pritiskom in katerega stena je še nenavrtana, premaknejo tesnilno ploščo v ustrezen končni položaj, ko se tesnilno območje nahaja vstran od mesta navrtanja glavnega cevovoda, na mestu navrtanja pa se nahaja prehod za vrtalno orodje. Na ohišje namestijo vrtalno pripravo in vrtalno orodje vstavijo skozi omenjeni prehod ter zatem navrtajo steno glavnega cevovoda. Po izvlečenju vrtalnega orodja z zasukom tesnilne plošče v drug končni položaj zaprejo vrtino v glavnem cevovodu, po katerem se lahko tačas vseskozi pretaka medij pod pritiskom. Ko je vrtina zaprta, z ohišja odstranijo vrtalno pripravo z vrtalnim orodjem in zatem na ohišje namestijo individualni priključni vod, ki je predviden za hidravlično povezavo z glavnim cevovodom. Zatem tesnilno ploščo ponovno premaknejo v drug končni položaj, tako da prehod, ki je pred tem služil za dostop vrtalnega orodja do zunanje površine stene glavnega cevovoda, odtlej služi za izstop hidravličnega medija iz glavnega cevovoda v omenjeni priključni vod. Na ta način je torej mogoče vzpostaviti hidravlično povezavo med glavnim cevovodom in omenjenim priključnim vodom, ne da bi bilo pri tem potrebno prekiniti pretok medija v glavnem cevovodu. Po drugi strani je možna tudi prekinitev te hidravlične povezave med glavnim cevovodom in omenjenim priključnim vodom, kar se doseže s opremikom tesnilne plošče v drug končni položaj, v katerem je preko vrtine v steni glavnega cevovoda nameščeno tesnilno območje tesnilne plošče, medtem ko se omenjeni prehod nahaja izven območja vrtine oz. se z vrtino ne prekriva. Kakorkoli je vsaj na prvi pogled tovrstna rešitev povezana s številnimi prednostmi, iz prakse izhajajo tudi določene pomanjkljivosti. Prva pomanjkljivost je ta, da je izdelava ozobja na obodu razmeroma zahtevna operacija, katere izvajanje se odraža v visokih stroških izdelave in temu primernih cenah izdelkov. Nadalje je pri obstoječi izvedbi drsne plošče treba poskrbeti po eni strani za ustrezno uležiščenje tesnilne plošče zaradi potrebnega premikanja iz enega v drug končni položaj, po drugi strani pa tudi za pogon, ki omogoča to premikanje. Kot je bilo omenjeno, je v ta namen predviden dodaten zobnik, ki ga je spet potrebno izdelati s pomočjo zahtevnih in stroškovno intenzivnih tehnočoških operacij, po drugi strani pa ga tudi ustrezno uležiščiti v ohišju, kar spet narekuje potrebo po izvedbi ustreznega ležišča in razen tega tudi po dodatnem prostoru v ohišju. Za nemeček se pogosto dogaja, da po dolgotrajni uporabi zapornega organa premikanje tesnilne plošče lahko postane bistveno bolj oteženo kot pri pravkar vgrajenem izdelku. Kot seje v praksi že večkrat izkazalo, to privede do poškodbe ozobja bodisi na tesnilni plošči ali na zobniku, v obeh primerih pa praktično do onesposobitve celotnega zapornega organa. V tem primeru je potrebno zamenjati celoten zaporni organ, t.j. ventil ali zasun, v katerem je vgrajena tovrstna tesnilna plošča, pri čemer pa za nameček v večini primerov zamenjave preprosto ni mogoče izvesti brez prekinitve tokokroga v glavnem cevovodu.Such shut-off bodies, whether as valves or latches, are widely known from commercial documentation, and some such solutions are also available in the patent literature. EP 0 024 741 deals with the problem of rotation of the main pipe in which the pressurized media flows during drilling. However, the said solution focuses solely on the problem of efficient removal of the chips, which is achieved by the special drilling tool design. The applicant also knows from the commercial documentation other solutions (eg from the prospectuses of the German hydraulic equipment manufacturer BOPP & REUTHER GmbH). Such prison authorities, i.e. valves or valves, adapted to be fitted to the main pipeline at the location of the desired connection, and comprise a suitable housing and mounting means by which the housing can be fitted tightly to the perimeter of the main pipeline. On the one hand, it is possible to install on the one hand a suitable drilling device for drilling the main pipeline, and on the other hand, to attach a connecting line, which is intended to establish a suitable hydraulic connection between the individual connection and said main pipeline. Further, a housing plate is provided in the housing, comprising a sufficiently large sealing area and a passage for drilling tools, by means of which the wall of the main pipeline in which the medium under pressure is flowed at the desired location without having to interrupt the flow through the main pipeline. For this purpose, said sealing plate is movable to two end positions. In the first end position, the sealing area of the sealing plate is located outside of the main pipeline thrust area, and the drill bit passage is located above the thrust location on the outer surface of the main pipeline wall. In the remaining end position of the sealing plate, the sealing area of the sealing plate is located above the pivot point of the main pipeline, and the sealing area of the sealing plate is displaced away from the location of the sealing. The movement of said sliding plate from one final position to another takes place as a rotation of that sliding plate around a pivot by a given angle, which in practice is approximately 45 °. For this purpose, the sealing plate on the circumference is provided with a tooth with which the gearbox is engaged, which is pivoted in the housing. After attaching the housing to the outer perimeter of the main pipeline, in which the pressurized media flows and whose wall is not yet drawn, the sealing plate is moved to the appropriate end position when the sealing zone is away from the pivot point of the main pipeline and a passage is located at the point of drilling. for drilling tools. A drilling device is mounted on the housing and a drilling tool is inserted through said passage and subsequently drilled into the wall of the main pipeline. After extracting the drilling tool by rotating the sealing plate to another end position, it closes the borehole in the main pipeline, through which the pressurized medium can flow continuously. When the borehole is closed, the drilling rig is removed from the housing with a drilling tool and subsequently an individual connecting line is provided on the housing intended for hydraulic connection to the main pipeline. The sealing plate is then repositioned to a different end position so that the passage previously used to access the drilling tool to the outer wall surface of the main pipeline will then serve to exit the hydraulic medium from the main pipeline into said connecting line. In this way, it is possible to establish a hydraulic connection between the main pipeline and said connecting line without interrupting the flow of medium in the main pipeline. On the other hand, it is also possible to break this hydraulic connection between the main pipeline and said connecting line, which is achieved by furnishing the sealing plate to another end position in which a sealing area of the sealing plate is mounted over the bore in the wall of the main pipeline while said passage located outside the well area. it does not overlap with the well. However, at least at first glance, such a solution is linked to a number of advantages. The first disadvantage is that the manufacturing of a perimeter tooth is a relatively demanding operation, the implementation of which is reflected in the high cost of production and the corresponding product prices. Furthermore, in the existing version of the sliding plate, it must be ensured, on the one hand, that the sealing plate is properly secured in order to move from one end to another in the necessary position, and, on the other, to the actuator which enables this movement. As mentioned, an additional sprocket is provided for this purpose, which again needs to be made with the help of demanding and cost-intensive technical operations, and on the other hand it is properly mounted in the housing, which again necessitates the need for a suitable bearing and in addition even after extra space in the case. For a German, it often happens that after prolonged use of the shut-off body, moving the sealing plate can become significantly more difficult than with the product just installed. As has been proven in practice many times, this results in damage to the tooth either on the sealing plate or on the sprocket, and in both cases virtually disabling the entire constipation. In this case, the entire prison authority needs to be replaced, i.e. a valve or valve in which such a sealing plate is installed, but in most cases the replacement cannot simply be carried out without breaking the circuit in the main pipeline.

Pri nadaljnji rešitvi po DE 29 18 555 (Hawle) je predvidena zaporna plošča, ki je translacijsko premakljiva iz enega v drug položaj. Pred vrtanjem se plošča odmakne, zaradi Časar lahko opilki oz. ostružki padajo v prostor za vodenje plošče, od koder jih zatem vodni tok postopoma odplakne naprej po cevovodu, kjer lahko povzročajo motnje v delovanju drugih zapornih organov ali z vodo iz cevovoda dospejo celo do uporabnika ter s tem ogrožajo njegovo zdravje in okvare naprav, ki so priključene na cevovod.A further solution according to DE 29 18 555 (Hawle) provides a closure plate which is translationally movable from one position to another. Before drilling, the plate moves away, which can cause sawing or sawing. the shavings fall into the control room of the panel, from which the water stream gradually flushes further down the pipeline, where they can cause malfunction of other shut-off bodies or, even with the water from the pipeline, reach the user, thereby endangering his health and damage to devices that are connected to the pipeline.

Pričujoči izum se nanaša na zaporni organ, ki je predviden za izvedbo cevnega priključka na takoimenovanem glavnem cevovodu. Tovrsten zaporni organ sestoji iz ohišja, ki je s pomočjo ustreznih pritrdilnih sredstev namestljivo na obod stene vsakokrat razpoložljivega glavnega cevovoda, na katerem se z navrtanjem omenjene stene cevovoda v splošnem brez potrebe po prekinitvi pretakanja medija pod pritiskom po cevovodu izvede individualni priključek. Omenjeno ohišje je prirejeno za sodelovanje z vsakokratnim pritrdilnim sklopom priključnega voda in alternativno z vsakokrat ustrezno vrtalno pripravo za izvedbo vrtine v steni glavnega cevovoda. V ohišju je uležiščena tesnilna plošča, ki je opremljena z dovolj obsežnim tesnilnim območjem za prekrilje vrtine v steni glavnega cevovoda kot tudi s prehodom, ki omogoča bodisi dostop vrtalnega orodja vrtalne priprave do za izvedbo vrtine v steni glavnega cevovoda predvidene lokacije ali tudi vzpostavitev hidravlične povezave med glavnim cevovodom in priključnim vodom po izvedbi vrtine v steni glavnega cevovoda.The present invention relates to a shut-off body which is intended to provide a pipe connection on a so-called main pipeline. Such a shut-off body consists of a housing which, by means of suitable fastening means, is mounted on the periphery of the walls of the main pipeline available at all times, by rotating said pipeline wall without the need to interrupt the flow of pressurized medium through the pipeline. Said housing is adapted to cooperate with the respective attachment assembly of the connecting line and, alternatively, with a suitable drilling device for each borehole in the main pipeline wall. The housing includes a sealing plate equipped with a sufficiently large sealing area to cover the borehole in the main pipeline wall as well as a passage allowing either access of the drilling tool's drilling tool to the borehole in the main pipeline wall of the intended location or also to establish a hydraulic connection. between the main pipeline and the conduit after the hole in the main pipeline wall.

Po izumu je z upravljalnim organom oblikosklepno povezana, k ohišju zapornega organa tesno prilegajoča se tesnilna plošča z zasukom okoli svojega v omenjenem ohišju razpoložljivega vrtišča premakljiva iz enega končnega položaja, ko z lokacijo vrtine v steni glavnega cevovoda sovpada njeno tesnilno območje, v drug končni položaj, ko z lokacijo vrtine v steni glavnega cevovoda sovpada njen prehod in obratno. Pri prednostni izvedbi je ta okoli svojega na/v ohišju razpoložljivega vrtišča za ustrezen kot zasukljiva zaporna plošča opremljena z odprtino, medtem ko okoli svoje osi vrtenja zasukljiv upravljalni organ obsega na sebi glede na omenjeno os vrtenja ekscentrično razporejen somik, ki sega v omenjeno odprtino zaporne plošče, s čimer je med upravljalnim organom in v svojem vrtišču avtonomno uležiščeno zaporno ploščo vzpostavljena oblikosklepna povezava, zahvaljujoč kateri je zaporna plošča okoli vrtišča zasukljiva v odvisnosti od zasuka zapornega organa.According to the invention, it is formally connected to the control body, the sealing plate, which is tightly fitting to the shut-off body, is rotated from one end position in said housing to said pivot, when its sealing area coincides with the location of the hole in the main pipeline wall, to another end position. when the location of the well in the main pipeline wall coincides with its passage and vice versa. In a preferred embodiment, the pivoting control body is provided with an opening around its on / in the housing of the available pivot for a suitable rotatable locking plate, while around its axis of rotation, the rotatable control body comprises eccentrically arranged auger extending into said shut-off opening about said axis of rotation panels, thereby forming a locking connection between the control body and the pivot panel autonomously mounted in its pivot, due to which the closure panel is rotatable around the pivot depending on the rotation of the closure body.

Pri nadaljnji od možnih izvedb je v ohišju zapornega uležiščena, okoli vrtišča, ki pa v tem primeru sovpada z osjo vrtenja zapornega organa, zasukljiva tesnilna plošča nameščena na upravljalnem organu in z njim oblikosklepno povezana, pri čemer je ta upravljalni organ skupaj s tesnilno ploščo za vsakokrat potreben kot zasukljiv okoli omenjene osi vrtenja.In a further embodiment, a rotatable sealing plate is mounted on the control body and connected to it in a locking housing, around the pivot, which in this case coincides with the axis of rotation of the shutter, in which case the control body is coupled with the sealing plate for needed each time as rotating about said axis of rotation.

Na ta način je pri obeh omenjenih izvedbah uležiščenja zaporne plošče zahvaljujoč vzpostavitvi oblikosklepne povezave med upravljalnim organom, ki je v ohišju uležiščen z možnostjo zasuka za vsakokrat potreben kot okoli omenjene osi vrtenja, in tesnilno ploščo poleg možnosti zasuka te tesnilne plošče okoli omenjene osi vrtenja omogočen tudi prenos vrtilnega momenta, ki je potreben za zasuk tesnilne plošče za vsakokrat potreben kot iz enega končnega položaja v preostali končni položaj in obratno.In this way, thanks to the closure connection between the control body, which is rotatable in each case with the possibility of rotation in each case as needed about said axis of rotation, and the sealing plate in addition to the possibility of rotation of this sealing plate around said axis of rotation, also the torque transfer required to rotate the sealing plate for the required angle from one end position to the remaining end position and vice versa.

Pri izvedbi, kjer os vrtenja upravljalnega organa sovpada z vrtiščen zaporne plošče, je nadalje upravljalni organ v ohišju okoli osi vrtenja za vsakokrat potreben kot zasukljivo uležiščen s pomočjo vsaj v bistvu cilindričnega stebla, obris upravljalnega organa na mestu vzpostavitve oblikosklepne povezave s tesnilno ploščo pa je nekrožen oz. necilindričen. Se zlasti je v tem primeru prednostno, če je upravljalni organ na mestu vzpostavitve oblikosklepne povezave s tesnilno ploščo opremljen z vsaj enim posnetjem, še zlasti z vsaj, dvema diametralno nasproti razporejenima posneljema. Razen tega je prosti konec upravljalnega organa posnet, še zlasti štirikotno posnet. Po drugi strani je tesnilna plošča na mestu vzpostavitve oblikosklepne povezave z upravljalnim organom opremljena z nasedom, katerega obris je prirejen obrisu upravljalnega organa, še zlasti z nasedom, ki je v osnovi cilindrično zasnovan, vendar opremljen z vsaj enim kot tetiva potekajočim površinskim odsekom, najbolj prednostno pa z nasedom, kije v osnovi cilindrično zasnovan, vendar opremljen z vsaj dvema diametralno nasproti razporejenima ter v smislu tetiv potekajočima površinskima odsekoma.In an embodiment where the axis of rotation of the control body coincides with the rotation of the locking plate, the control body in the housing around the axis of rotation is in each case required as a pivotably mounted bearing with at least essentially a cylindrical stem, and the outline of the control body at the point of establishing a locking connection with the sealing plate is uncirculated or. non-cylindrical. Particularly in this case, it is advantageous if the control body is provided with at least one recording at the point of connection with the sealing plate, in particular with at least two diametrically opposed recordings. In addition, the free end of the control body is taped, especially four-taped. On the other hand, the sealing plate at the point of making a close connection with the control body is provided with a contour whose contour is adapted to the contour of the control body, in particular a contour fundamentally cylindrical but equipped with at least one tendon running surface section, most and preferably with a support substantially cylindrical in design, but provided with at least two diametrically opposed spaced sections and, in terms of tendons, extending surface sections.

Izum bo v nadaljevanje odrobneje obrazložen na osnovi primera izvedbe, ki je prikazan na priloženi skici, kjer kažejoThe invention will now be explained in more detail on the basis of the embodiment shown in the accompanying drawing showing

Sl. 4 pa nadaljnji primer izvedbe oz. premakljivosti tesnilne plošče v ohišju zapornega organa.FIG. 4 is a further example of implementation or movability of the sealing plate in the housing of the shut-off body.

Zaporni organ 1, ki je v splošnem lahko izveden kot zasun ali tudi kot ventil, je prirejen za namestitev na glavni cevovod, ki na skici sicer ni posebej prikazan. Namestitev zapornega organa 1 se izvrši na mestu izvedbe želenega individualnega priključka na omenjeni cevovod, npr. vodovodnega priključka do posamezne zgradbe. Zaporni organ 1 obsega ustrezno ohišje 2, za njegovo pritrditev na glavni cevovod pa so predvidena ustrezna pritrdilna sredstva. Eno od možnosti za pritrditev predstavljajo kot črka U ukrivljene objemke, ki so strokovnjakom z relevantnega področja tehnike nedvomno znane in s pomočjo katerih je mogoče ohišje 2 tesno prilegajoče se pritrditi na obod stene glavnega cevovoda. Vsakokratna objemka, ki na skici prav tako ni prikazana, je na svojih ravnih prostih koncih opremljena z navojem in vstavljiva skozi vsakokrat razpoložljivo prejemno odprtino 21, 22 na ohišju 2.The shut-off body 1, which can generally be designed as a latch or also as a valve, is adapted for installation on a main pipeline, which is not otherwise shown in the drawing. The installation of the shut-off body 1 is performed at the location of the desired individual connection to said pipeline, e.g. plumbing connection to each building. The closure body 1 comprises a suitable housing 2, and suitable fixing means are provided for its attachment to the main pipeline. One of the mounting options is a U-shaped clamp, which is undoubtedly known to those skilled in the art and by means of which the housing 2 can be fitted tightly to the periphery of the main pipe wall. Each clamp, which is also not shown in the drawing, is threaded at its flat, free ends and can be inserted through the available opening 21, 22 on the housing 2 at each time.

Nadalje je ohišje 2 prirejeno za prejem - alternativno - bodisi pritrdilnega sklopa 3 priključnega voda 30 ali ustrezne vrtalne priprave, ki na skici ni posebej prikazana. Pritrditev je v obeh primerih izvedljiva s pomočjo vijakov 31, ki so priviti v ustrezna gnezda 23 na ohišju 2.Further, the housing 2 is adapted to receive - alternatively - either the mounting assembly 3 of the connecting line 30 or the corresponding drilling device, which is not shown separately in the drawing. In both cases, the fastening is possible by means of screws 31 which are screwed into the corresponding sockets 23 on the housing 2.

Priključni vod 30 je predviden za vzpostavitev ustrezne hidravlične povezave med vsakokratnim individualnim priključkom in omenjenim glavnim cevovodom. V ohišju 2 je na voljo zaporna plošča 4, ki je v danem primeru in prednostno na kar najbolj preprost način izvedena iz enega dela in je po eni strani opremljena z dovolj obsežnim tesnilnim območjem 41, ki zadostuje za prekritje v steni cevovoda izvedene vrtine, in po drugi strani s prehodom 42 za vrtalno orodje oz. alternativno za pretok medija iz glavnega cevovoda v priključni vod 30. Za zaporni organ 1 po izumu je značilno, da je zaporna plošča 4 v ohišju 2 nameščena zasukljivo okoli vrtišča 40, ki v primeru po sl. 1 do 3 sovpada z osjo 50 vrtenja upravljalnega organa 5. V tem primeru (sl. 1 do 3) je plošča 4 s pomočjo oblikosklepne zveze nameščena na upravljalnem organu 5, kar obenem z možnostjo zasuka plošče 4 za vsakokrat potreben kot okoli osi 40, 50 vrtenja zagotavlja tudi prenos momenta, ki je potreben za premik plošče 4 iz enega končnega položaja (Sl. 1) v drug končni položaj (Sl. 2) ali obratno. V prikazanem primeru je oblikosklepna povezava med upravljalnim organom 5 in ploščo 4 dosežena na preprost način s pomočjo diametralno nasproti razporejenih posnetij 51, 52 na cilindričnem steblu 53 upravljalnega organa 5 ter s pomočjo kot tetivi potekajočih, diametralno nasproti razporejenih ravnih ploskovnih odsekov 43, 44 sicer v osnovi cilindrično zasnovanega naseda 45 plošče 4 (Sl. 3). Omenjeni upravljalni organ 5 je v danem primeru opremljen s štirikotno posnetim prostim koncem 54, ki je primeren za prejem ustreznega pripomočka, npr. ustrezne ročice, ključa ali matice, ki omogoča doseganje ustreznega vrtilnega momenta, ki je potreben za zasuk upravljalnega organa 5 okoli osi 50 vrtenja ob sočasnem zasuku tesnilne plošče 4 okoli taiste osi 50 iz enega končnega položaja (Sl. 1) v drug končni položaj (Sl. 2) in obratno.The connection line 30 is provided to establish a suitable hydraulic connection between the respective individual connection and said main pipeline. In the housing 2 there is provided a locking plate 4, which is optionally made in one case and preferably in the simplest possible way, from one part and on the one hand is provided with a sufficiently large sealing area 41 sufficient to cover the borehole wall in the pipework, and on the other hand, with passage 42 for drilling tools or drill bits. alternatively for the flow of medium from the main pipeline into the conduit 30. The closure body 1 according to the invention is characterized by the fact that the closure plate 4 in the housing 2 is pivoted about a pivot 40, which in the case of FIG. 1 to 3 coincide with the axis 50 of the rotation of the control body 5. In this case (Figs. 1 to 3), the panel 4 is mounted on the control body 5 by means of a locking connection, which at the same time is necessary for the angle 4 about the axis 40, 50 rotation also provides the transfer of the torque required to move the plate 4 from one end position (Fig. 1) to another end position (Fig. 2) or vice versa. In the example shown, the shape-locking connection between the control body 5 and the plate 4 is easily achieved by means of diametrically opposite arranged clips 51, 52 on the cylindrical stem 53 of the control body 5 and by means of tendons of straight, diametrically opposite arranged flat plane sections 43, 44 otherwise. at the base of the cylindrically designed seat 45 of plate 4 (Fig. 3). Said control body 5 is optionally provided with a quadrilateral free end 54 which is suitable for receiving a suitable accessory, e.g. a suitable lever, wrench or nut to achieve the appropriate torque required to rotate the control body 5 about the axis of rotation 50 while simultaneously rotating the sealing plate 4 about the same axis 50 from one end position (Fig. 1) to another end position ( Fig. 2) and vice versa.

Nadaljnji primer izvedbe zaporne plošče plošče 4 je prikazan na sl. 4. V tem primeru je plošča 4 zasukljiva okoli vrtišča 4, ki je predvideno v ohišju 2. Oblikosklepna povezava med ploščo 4 in upravljalnim organom 5, ki je vrtljiv okoli osi 50, je realizirana s pomočjo podolgovate odprtine 48 v plošči 4 in somika 55, ki je na upravljalnem organu 5 nameščen ekscentrično glede na os 50 vrtenja upravljalnega organa 5 in sega v omenjeno luknjo 48 v plošči 4. S tem je zaporna plošča 4 v ohišju 2 uležiščena avtonomno, pri čemer je predvideno, da je okoli omenjenega vrtišča 40 zasukljiva za približno 60°. Zahvaljujoč prestavnemu razmerju, ki ga zagotavlja obravnavana izvedba oblikosklepne povezave med ploščo 4 in upravljalnim organom 5 s pomočjo ekscentrično nameščenega somika 55, vstavljenega v odprtino 48 plošče 4, je v obravnavanem primem za zasuk plošče 4 za 60° potreben zasuk zapornega organa za vsaj približno 180°, ki je razmeroma običajen na področju upravljanja tovrstnih zapornih organov in iz tega razloga uporabnike zelo sprejemljiv ter zatorej še zlasti prednosten.A further embodiment of the locking plate of panel 4 is shown in FIG. 4. In this case, the plate 4 is rotatable around the pivot 4 provided in the housing 2. The shape-lock connection between the plate 4 and the control body 5 which is rotatable about the axis 50 is realized by means of an elongated opening 48 in the plate 4 and the snap 55 , which is mounted eccentrically on the control body 5 with respect to the axis 50 of rotation of the control body 5 and extends into said hole 48 in the plate 4. The locking plate 4 in the housing 2 is thus positioned autonomously, and is provided to be around said pivot 40 rotatable by about 60 °. Owing to the gear ratio provided by the present embodiment, the shape-locking connection between the plate 4 and the control body 5 by means of an eccentrically positioned snap 55 inserted into the opening 48 of the plate 4 requires a rotation of the shut-off body for at least about 60 ° in the foregoing. 180 °, which is relatively common in the management of such prisons and therefore very user friendly and therefore particularly preferred.

Pri namestitvi ohišja 1 na obod glavnega cevovoda pred navijanjem le-tega zaradi realizacije individualnega priključka z ustreznim zasukom upravljalnega organa 5 premaknemo tesnilno ploščo v položaj po Sl. 2, ko položaj prehoda 42 v tesnilni plošči 4 sovpada s položajem lokacije navrtanja glavnega cevovoda. Zatem s pomočjo vijakov 31 na ohišje 2 pritrdimo ustrezno vrtalno pripravo, katere vrtalno orodje je vstavljivo skozi prehod 42 tesnilne plošče 4. Pri tem ni izključena možnost tudi drugačnega načina navrtanja glavnega cevovoda, po katerem se med navrtanjem lahko vseskozi pretaka medij pod pritiskom, vsekakor pa je pri tem predvideno, da vrtalno orodje poteka skozi prehod 42 v tesnilni plošči 4. Med vrtanjem se ostružki zadržujejo na površini plošče 4 in/ali ohišja 2 in v nobenem primeru ne morejo prodreti v območja, od koder bi po zasuku plošče 4 lahko vstopili v notranjost cevododa. Po izvršenem navrtanju cevovoda vrtalno orodje umaknemo vsaj toliko, da izstopi iz območja prehoda 42 v tesnilni plošči 4, nakar z zasukom upravljalnega organa 5 okoli osi 50 ter s tem zasukom tesnilne plošče 4 slednjo premaknemo iz enega končnega položaja (Sl. 2) v drug končni položaj (Sl. 1), tako da je lokacija vrtine v steni cevovoda prekrita s tesnilnim območjem 41 tesnilne plošče 4. Na ta način je preprečeno iztekanje medija iz glavnega cevovoda v okolico. Temu sledi namestitev pritrdilnega sklopa 3 priključnega voda 30, kar je v prikazanem primeru izvedljivo s pomočjo vijakov 31.When installing the housing 1 on the perimeter of the main pipeline prior to winding it, in order to realize the individual connection with a suitable rotation of the control body 5, move the sealing plate to the position of FIG. 2, when the position of passage 42 in sealing plate 4 coincides with the position of the pivot location of the main pipeline. Then, by means of screws 31, a suitable drilling device is mounted on the housing 2, the drilling tool of which can be inserted through the passage 42 of the sealing plate 4. This does not exclude the possibility of a different way of rotation of the main pipeline, by which the pressurized medium can flow at all times during drilling. however, it is contemplated that the drilling tool passes through passage 42 in sealing plate 4. During drilling, the chips remain on the surface of the plate 4 and / or the housing 2 and in no case can penetrate the areas from which, after rotation of the plate 4, entered the inside of the pipeline. After the piping is drilled, the drilling tool is removed at least until it exits the passage area 42 in the sealing plate 4, and then by rotating the control body 5 about the axis 50 and thereby rotating the sealing plate 4, the latter is moved from one end position (Fig. 2) to another. end position (Fig. 1) so that the location of the hole in the wall of the pipeline is covered by the sealing area 41 of the sealing plate 4. This prevents the flow of media from the main pipeline into the surrounding area. This is followed by the installation of the mounting assembly 3 of the connection line 30, which in the example shown is feasible by means of screws 31.

Po namestitvi priključnega voda 30 s ponovnim zasukom upravljalnega organa 5 dosežemo zasuk tesnilne plošče 4 iz trenutnega končnega položaja (Sl. 2) v preostali končni položaj (Sl. 2), v katerem prehod 42 sovpada z vrtino, izvedeno v steni glavnega cevovoda. Zahvaljujoč nazadnje omenjenemu zasuku tesnilne plošče 4 je vzpostavljena hidravlična povezava med glavnim cevovodom in priključnim vodom 30, tako da medij iz glavnega cevovoda lahko skozi prehod 42 v tesnilni plošči 4 neovirano izteka v priključni vod 30.After installing the conduit 30 by re-rotating the control body 5, the sealing plate 4 is rotated from the current end position (Fig. 2) to the remaining end position (Fig. 2), in which passage 42 coincides with a bore made in the wall of the main pipeline. Thanks to the aforementioned rotation of the sealing plate 4, a hydraulic connection is established between the main pipeline and the conduit 30, so that the medium from the main duct can flow freely into the conduit 30 through the passage 42 in the sealing plate 4.

To hidravlično povezavo med glavnim cevovodom in priključnim vodom 30 je mogoče s ponovnim zasukom tesnilne plošče 4 iz končnega položaja po sl. 2 v drug končni položaj po sl. 1 po potrebi spet prekiniti, zlasti npr. v primeru popravil posameznih porabnikov ali armatur, ki so hidravlično povezane s priključnim vodom 30.This hydraulic connection between the main pipeline and the conduit 30 is possible by re-rotating the sealing plate 4 from the end position according to FIG. 2 to another end position according to FIG. 1 interrupt again if necessary, in particular e.g. in the case of repairs to individual consumers or fittings that are hydraulically connected to the connection line 30.
