Description
Opisani izum odnosi se na uređaj za povezivanje elemenata cjevovoda, i to jednog ravnog kraja i jednog proširenja u kome se nalazi brtvilo koja se radijalno sabija. Taj uređaj obuhvaća: The described invention relates to a device for connecting pipeline elements, namely one flat end and one extension in which there is a seal that is compressed radially. This device includes:
- prvu oslonu napravu koja je napravljena tako da čini cjelinu sa prvim elementom cjevovoda, i koja ima najmanje jednu pokretačku ručku, - the first support device which is made so that it forms a whole with the first pipeline element, and which has at least one actuating handle,
- drugu oslonu napravu koja je napravljena tako da čini cjelinu sa drugim elementom cjevovoda, i - another support device that is made so that it forms a whole with another element of the pipeline, i
- najmanje jednu zateznu polugu prilagođenu, s jedne strane da surađuje sa krajem ručke, i s druge strane da se okreće na drugoj oslonoj napravi oko jedne osi, naročito radi suradnje otvora izvedenog na zateznoj poluzi sa rukavcem izrađenim na vanjskoj površini spomenute druge oslone naprave. - at least one tensioning lever adapted, on the one hand, to cooperate with the end of the handle, and on the other hand, to rotate on the second support device around one axis, especially for the cooperation of the opening made on the tension lever with the sleeve made on the outer surface of the mentioned second support device.
Ovi elementi cjevovoda povezuju se na uobičajeni način, umetanjem ravnog cilindričnog kraja, ili ravnog kraja, prvog elementa u odgovarajuće proširenje drugog elementa, pri čemu se u tom proširenju nalazi unutrašnje brtvilo koja se radijalno sabija između ta dva elementa dok se ostvaruje veza. These piping elements are connected in the usual way, by inserting the straight cylindrical end, or flat end, of the first element into the corresponding expansion of the second element, the expansion containing an internal seal that compresses radially between the two elements as the connection is made.
Poznato je da se za jednu takvu operaciju koristi pomoćni uređaj za spajanje, koji ima dvije oslone naprave koje čine cjelinu sa svakim od pripadajućih elemenata cjevovoda. It is known that for one such operation, an auxiliary connection device is used, which has two support devices that form a whole with each of the associated elements of the pipeline.
Kod jednog poznatog uređaja, koji prodaje njemačko poduzeće HALBERGERHÜTTE, prva oslona naprava je naprava za pritezanje koja se sastoji od jednog spojnog steznog prstena, pričvršćenog na vanjskoj površini ravnog kraja. Ova naprava za pritezanje ima dva dijametralno suprotna cilindrična nosača, u vidu radijalnih rukavaca koji se pružaju prema napolje od ravnog kraja. Na tim se nosačima mogu okretati pripadajuće pokretačke naprave od kojih se svaka sastoji od jedne šestostrane matice na kojoj postavljen jedan rukavac. Osi rukavca i šestostrane matice su paralelne ali odvojene, tako da pokretačka naprava zbog svog okretanja oko cilindričnog nosača formira pokretačku polugu, odnosno ručku. In one known device, sold by the German company HALBERGERHÜTTE, the first supporting device is a tightening device consisting of a connecting clamping ring, fixed on the outer surface of the flat end. This tightening device has two diametrically opposite cylindrical supports, in the form of radial sleeves that extend outward from the flat end. The associated drive devices can be rotated on these supports, each of which consists of a six-sided nut on which a sleeve is placed. The axes of the sleeve and the hexagonal nut are parallel but separate, so that the actuating device, due to its rotation around the cylindrical support, forms an actuating lever, i.e. a handle.
Druga oslona naprava sastoji se od jednog poluprstena postavljenog na proširenje, koji se produžuje sa jednim lancem koji se pruža preko ostalog dijela obujma proširenja, tako da učvršćuje oslonu napravu na njenom mjestu. Ova druga oslona naprava ima dva dijametralno suprotna rukavca, koji predstavljaju radijalne ispuste koji se pružaju prema napolje od proširenja. The second support device consists of one half-ring mounted on the extension, which is extended with a single chain that extends over the rest of the circumference of the extension, so as to secure the support device in place. This second support device has two diametrically opposite arms, which represent radial outlets that extend outward from the extension.
Uređaj za spajanje dopunjen je sa dvije zatezne poluge od kojih svaka, s jedne strane surađuje sa rukavcem jedne ručke, dok je s druge strane okretno postavljena na jedan rukavac izveden na drugoj oslonoj napravi. The connecting device is supplemented with two tension levers, each of which, on one side, cooperates with the sleeve of one handle, while on the other side, it is rotatably placed on a sleeve made on another support device.
Radnik, ili dva radnika u slučaju maksimalnog sabijanja brtvila, istovremeno okreću dvije šestostrane matične naprave za pritezanje ravnog kraja. Pod djelovanjem sile povlačenja zateznih poluga, proširenje se privlači ka nepokretnom vanjskom ravnom kraju, sve dok ovaj ne dođe u dodir sa aksijalnim uporom na dnu proširenja. Time su elementi cjevovoda povezani, a brtvilo je radijalno sabijeno. A worker, or two workers in the case of maximum sealant compression, simultaneously turn two six-sided nut devices to tighten the flat end. Under the action of the pulling force of the tension levers, the extension is drawn towards the stationary outer flat end, until it comes into contact with the axial stop at the bottom of the extension. The pipeline elements are thus connected, and the sealant is radially compacted.
Međutim, ovaj uređaj za spajanje nije prilagođen za sve vrste brtvila, a posebno ne odgovara kompozitnim brtvilima sa elementima za učvršćivanje koji omogućuju zatvaranje spoja elemenata cjevovoda. However, this jointing device is not suitable for all types of sealants, and in particular it is not suitable for composite sealants with fastening elements that allow the connection of pipeline elements to be closed.
U stvari, međusobno poravnavanje ova dva elementa cjevovoda prije spajanja jedino određuje radnik, bez pomoći mjernih aparata ili dodatnih uređaja za viziranje. Na taj način može doći do odstupanja između osi ta dva elementa, koje može dostići vrijednost od 6 do 8 °. Tokom početne faze sklapanja, ravni kraj se ne umeće duž uzdužne osi proširenja, tako da djeluje neravnomjerno na brtvilo. Ovo može izazvati oštećenje, i to kidanje tog brtvila, naročito ako je odstupanje između osi veće od 3 °. In fact, the mutual alignment of these two pipeline elements before joining is determined solely by the worker, without the aid of measuring devices or additional sighting devices. In this way, there can be a deviation between the axes of these two elements, which can reach a value of 6 to 8 °. During the initial stage of assembly, the flat end is not inserted along the longitudinal axis of the expansion, so it acts unevenly on the sealant. This can cause damage, namely tearing of that seal, especially if the deviation between the axes is greater than 3 °.
Da bi se ublažili ovi nedostaci, izumom se predviđa ostvarivanje uređaja za povezivanje elemenata cjevovoda koji ima jednostavnu konstrukciju i omogućuje pravilno postavljanje tokom početne faze sklapanja, kao i zadovoljavajuće međusobno vođenje ova dva elementa tokom sklapanja, tako da odstupanje između uzdužnih osi ova dva elementa bude najmanje moguće tokom izvođenja operacije povezivanja. In order to mitigate these disadvantages, the invention envisages the realization of a device for connecting pipeline elements that has a simple construction and enables proper placement during the initial assembly phase, as well as satisfactory mutual guidance of these two elements during assembly, so that the deviation between the longitudinal axes of these two elements is least possible during the connection operation.
U tu svrhu, izum ima za predmet uređaj za povezivanje naprijed spomenute vrste, naznačen time što zatezna poluga i druga oslona naprava imaju pripadajuće graničnike, koji ograničavaju bar u jednom smjeru okretanje zatezne poluge u odnosu na spomenutu drugu oslonu napravu. For this purpose, the subject of the invention is a connection device of the aforementioned type, characterized in that the tension lever and the second support device have associated stops, which limit the rotation of the tension lever in relation to the mentioned second support device at least in one direction.
Izum omogućuje da se ostvare naprijed spomenuti ciljevi. U stvari, postojanje graničnika oslone naprave, izvedene kao jedna cjelina sa proširenjem i zatezna poluga, sprečava da se element cjevovoda sa proširenjem ne savije pod djelovanjem momenta izazvanog njegovom vlastitom masom. Na taj se način može ograničiti odstupanje između uzdužnih osi ova dva elementa tokom njihovog povezivanja. The invention makes it possible to achieve the goals mentioned above. In fact, the existence of the device support limiter, made as a single unit with an extension and a tension lever, prevents the element of the pipeline with an extension from bending under the action of the moment caused by its own mass. In this way, the deviation between the longitudinal axes of these two elements can be limited during their connection.

Kako je ukazano na slici 1, izum omogućuje nastavljanje prvog elementa 2 cjevovoda u drugi element 4 cjevovoda. As shown in Figure 1, the invention enables the continuation of the first element 2 of the pipeline into the second element 4 of the pipeline.
Spoj dvaju elemenata omogućen je umetanjem pravog cilindričnog kraja 6, također nazvanog ravni kraj, elementa 2 u odgovarajuće proširenje 8 elementa 4. The connection of the two elements is made possible by inserting the straight cylindrical end 6, also called the flat end, of the element 2 into the corresponding extension 8 of the element 4.
Proširenje 8 ima promjer veći od tijela 10 elementa 4, i ima aksijalni upor 12 na dnu proširenja na koji se oslanja ravni kraj 6 po završetku operacije povezivanja. The extension 8 has a diameter greater than the body 10 of the element 4, and has an axial abutment 12 at the bottom of the extension against which the flat end 6 rests upon completion of the joining operation.
Proširenje ima, pored ostalog, unutrašnji prstenasti žlijeb 14 u kome je smješteno prstenasto brtvilo 16. To brtvilo, na primjer ono koje je opisano u FR-A-2 679 622, a prodaje ga firma PONT-A-MOUSSON pod oznakom Standard Vi, ima metalne umetke 17 za učvršćivanje, koji omogućuju zabravljivanje sklopa dvaju elementa nakon njihovog povezivanja. The extension has, among other things, an internal annular groove 14 in which an annular seal 16 is placed. This seal, for example the one described in FR-A-2 679 622, sold by PONT-A-MOUSSON under the designation Standard Vi, it has metal inserts 17 for fastening, which allow the assembly of two elements to be locked after their connection.
Proširenje 8 ima, pored ostalog, sa vanjske strane prstenasti upor 18 uz koji je postavljena oslona naprava 20, prikazana shematski, a koja je objašnjena u vezi sa slikom 4. The extension 8 has, among other things, an annular stop 18 on the outside, against which a support device 20 is placed, shown schematically, and which is explained in connection with Figure 4.
Na analogni način oslona naprava 22 pričvršćena je sa vanjske strane na elementu 2, na rastojanju od brida njegovog ravnog kraja 6. In an analogous way, the support device 22 is attached from the outside to the element 2, at a distance from the edge of its flat end 6.
Kako je prikazano na slici 2, oslona naprava 22 je naprava za pritezanje, koja se sastoji od tri dijela 24 koji se mogu zakretati oko spojnice 26, tako da mogu obuhvatiti vanjsku površinu elementa 2. Dijelovi 241, 242, koji nisu povezani nekom spojnicom, mogu biti međusobno povezani pomoću zatezača 28 sa navojem, tako da sklop naprave za pritezanje može sačinjavati cjelinu sa elementom 2. As shown in Figure 2, the support device 22 is a tightening device, which consists of three parts 24 that can be rotated around the coupling 26, so that they can cover the outer surface of the element 2. The parts 241, 242, which are not connected by any coupling, can be connected to each other by means of a threaded tensioner 28, so that the assembly of the tightening device can form a whole with the element 2.
Naprava 22 za pritezanje obuhvaća dva dijametralno suprotna cilindrična nosača, izvedena u vidu rukavaca 30 koji se pružaju prema napolje. Ispusti 36, koji se pružaju prema napolje načinjeni su na rastojanju od cilindričnih nosača. Ovi su ispusti simetrični u odnosu na os YY, okomitu na dijametralnu os XX koja povezuje rukavce 30. The tightening device 22 comprises two diametrically opposite cylindrical supports, made in the form of sleeves 30 that extend outward. Outlets 36, which extend outwards, are made at a distance from the cylindrical supports. These discharges are symmetrical in relation to the axis YY, perpendicular to the diametral axis XX which connects the branches 30.
Slike 3A i 3B predstavljaju ručku 38 koja se treba okretati na rukavcima 30 naprave za pritezanje. Figures 3A and 3B represent the handle 38 to be rotated on the arms 30 of the tightening device.
Ova ručka 38 ima osnovnu ploču 40 koja je načinjena od dva polukružna dijela 42, sa istim središtem ali različitih promjera, međusobno povezana sa dva kosa upora 44 koji formiraju površine nalijeganja. Time je kutna putanja ručke ograničena na jedan poluokret. Ručka 38 ima u stvari dva krajnja položaja okretanja, definirana nalijeganjem upora 44 na ispust 36, kako je prikazano linijama crta-točka na slici 3A (u odnosnim položajima). This handle 38 has a base plate 40 which is made of two semi-circular parts 42, with the same center but different diameters, connected to each other by two oblique abutments 44 that form contact surfaces. This means that the angular trajectory of the handle is limited to one half-turn. The handle 38 actually has two end positions of rotation, defined by the abutment of the abutment 44 on the outlet 36, as shown by the dash-dot lines in Figure 3A (in the respective positions).
Na toj osnovnoj ploči koaksijalno je pričvršćena šestostrana matica 46, sa dva polukruga koji sačinjavaju osnovnu ploču 40. Na matici je postavljen ekscentrični element 48, na kome je načinjen rukavac 52, koji na svom slobodnom kraju ima cilindrični obod 54 promjera većeg od promjera rukavca. Uzdužna os tog rukavca prolazi duž gornjeg brida 56 šestostrane matice 46. A six-sided nut 46 is coaxially attached to that base plate, with two semicircles that make up the base plate 40. An eccentric element 48 is placed on the nut, on which a sleeve 52 is made, which at its free end has a cylindrical rim 54 with a diameter larger than the diameter of the sleeve. The longitudinal axis of this sleeve passes along the upper edge 56 of the hexagonal nut 46.
Osnovna ploča 40, šestostrana matica 46 i ekscentrični element 46, imaju poprečni otvor 57 za prolaz rukavca 30. The base plate 40, the hexagonal nut 46 and the eccentric element 46 have a transverse opening 57 for the passage of the sleeve 30.
Ručka 38 može se okretati oko rukavca 30 pomicanjem šestostrane matice, pomoću odgovarajućeg alata. Kako je naprijed rečeno, to je okretanje ograničeno pomoću dva upora 44 na okretnoj ploči. The handle 38 can be turned around the sleeve 30 by moving the hex nut, using a suitable tool. As previously stated, this rotation is limited by two stops 44 on the turntable.
Između ostalog, mogu se predvidjeti i dodatni elementi koji nisu prikazani, kao na primjer matica koja drži ručku na rukavcu 30 bez ometanja njenog okretanja. Among other things, additional elements that are not shown can be provided, such as a nut that holds the handle on the sleeve 30 without hindering its rotation.
Slika 4 prikazuje oslonu napravu 20 koja se postavlja na element 4. Naprava 20 je jedna obujmica koja obuhvaća oslono tijelo 58 čiji unutrašnji profil obuhvaća, gledano s prednje strane, dio C kruga koji odgovara luku od oko 240 °. Da bi se postavilo tijelo 58, ono se u početku pomiče duž tijela 10 elementa 4, promjera manjeg od promjera proširenja 8, a zatim se pomiče aksijalno sve dok ne nalegne na upor formiran na vanjskoj površini proširenja. Fig. 4 shows the support device 20 which is placed on the element 4. The device 20 is a single clamp that includes a support body 58 whose inner profile includes, seen from the front, part C of a circle corresponding to an arc of about 240 °. In order to place the body 58, it is initially moved along the body 10 of the element 4, with a diameter smaller than the diameter of the extension 8, and then it is moved axially until it rests against the abutment formed on the outer surface of the extension.
U tom cilju (slika 1) uzdužni unutrašnji profil tijela 58 ima upor 59 prilagođen uporu 18 načinjenom na vanjskom profilu proširenja 19, da bi se omogućila optimalna međusobna veza. To this end (Figure 1), the longitudinal internal profile of the body 58 has a stop 59 adapted to the stop 18 made on the external profile of the extension 19, to enable an optimal mutual connection.
Zone Z, koje se pružaju ispod horizontalne dijametralne osi X'X' tijela 58, formiraju graničnike koji ne dozvoljavaju radijalno odvajanje od proširenja 8 prilikom povezivanja dvaju elemenata 2, 4. Zones Z, which extend below the horizontal diametral axis X'X' of the body 58, form stops that do not allow radial separation from the extension 8 when connecting the two elements 2, 4.
Vanjska površina tijela 58 naprave 20 za pritezanje formira u blizini zone graničnika dvije ravnine 60 simetrične u odnosu na vertikalnu os Y'Y'. Dva dijametralna rukavca 62 načinjena su po jedan na svakoj od ravnina 60, a pružaju se radijalno prema napolje od naprave 20 za pritezanje. The outer surface of the body 58 of the tightening device 20 forms near the stop zone two planes 60 symmetrical with respect to the vertical axis Y'Y'. Two diametrical sleeves 62 are made one on each of the planes 60, and they extend radially outward from the device 20 for tightening.
Dva dodatna rukavca 64 postavljena su simetrično u odnosu na os Y'Y'. Ovi dodatni rukavci načinjeni su vertikalno iznad dijametralnih rukavaca 62, a imaju uzdužnu os paralelnu uzdužnoj osi rukavaca 62. Two additional sleeves 64 are placed symmetrically in relation to the axis Y'Y'. These additional sleeves are made vertically above the diametric sleeves 62, and have a longitudinal axis parallel to the longitudinal axis of the sleeves 62.
Gornji dio tijela 58 koje sačinjava napravu 20 za pritezanje sastoji se od obujmice 70, u kojoj su načinjeni otvori za hvatanje. The upper part of the body 58, which makes up the device 20 for tightening, consists of a clamp 70, in which the openings for catching are made.
Ukoliko je potrebno, tijelo 58 može se povezati sa jednim donjim komplementarnim držačem ili sektorom, koji nije prikazan, istog uzdužnog unutrašnjeg profila, naročito u slučaju elemenata cjevovoda velikog promjera. Tijelo i komplementarni sektor mogu se povezati sa bilo kojim elementima za prićvršćivanje, kao na primjer vijcima. If necessary, the body 58 can be connected to a lower complementary bracket or sector, not shown, of the same longitudinal internal profile, especially in the case of large diameter pipeline elements. The body and the complementary sector can be connected with any fastening elements, such as screws.
Oslona naprava 20, koja se sastoji samo od tijela 58, ili je dopunjena spomenutim sektorom, ne dozvoljava oštećenje obloge proširenja. Ovo se naročito odnosi na elemente cjevovoda predviđene za upotrebu u korozivnim sredinama, protiv kojih su ti elementi zaštićeni vanjskom oblogom od epoksidalnih smola ili polietilena. The support device 20, which consists only of the body 58, or is supplemented by the mentioned sector, does not allow damage to the lining of the extension. This especially applies to pipeline elements intended for use in corrosive environments, against which these elements are protected by an outer coating of epoxy resins or polyethylene.
Slika 5 prikazuje zateznu polugu 80 koja treba surađivati istovremeno sa ručkom 38 i sa rukavcima 62 i 64 postavljenim na oslonoj napravi 20. Figure 5 shows the tension lever 80 which should cooperate simultaneously with the handle 38 and with the sleeves 62 and 64 placed on the support device 20.
Zatezna poluga 80 ima oblik slova L, sa velikim horizontalnim krakom 81 i malim vertikalnim krakom 82, usmjerenim naviše. Donji otvor 84 načinjen je na kutu L-a, a gornji otvor 86 većeg promjera načinjen je pri kraju kraka 82. Otvor 86 smješten je približno iznad otvora 84, ali je nešto pomaknut u odnosu na njega prema kraku 81. The tension lever 80 is L-shaped, with a large horizontal arm 81 and a small vertical arm 82, pointing upwards. The lower opening 84 is made at the corner of L, and the upper opening 86 of a larger diameter is made at the end of the arm 82. The opening 86 is located approximately above the opening 84, but it is slightly moved in relation to it towards the arm 81.
Donji otvor 84 treba, kako je prikazano na slici 6, postaviti bez zapora na dijametralni rukavac 62 naprave 20. Gornji otvor 86 sa svoje strane prima dodatni rukavac 64 sa određenim zaporom. Na taj način postoji između zatezne poluge 80 i rukavca 64 ograničeni stupanj slobode okretanja. The lower opening 84 should, as shown in Figure 6, be placed without a stop on the diametric sleeve 62 of the device 20. The upper opening 86, on its part, receives an additional sleeve 64 with a certain stop. In this way, there is a limited degree of freedom of rotation between the tension lever 80 and the sleeve 64.
Na svom drugom kraju 88, zatezna poluga 80 ima dva ureza 90 i 92 koji se postupno spajaju sa rukavcem 52 ručke 38. At its other end 88, the tension lever 80 has two notches 90 and 92 which gradually mate with the sleeve 52 of the handle 38.
Svaki od ureza 90, 92 sastoji se od vertikalnog proreza 94, čiji je brid 96 udaljen od kraja 88 zatezne poluge, i produžuje se tangencijalno u dio 98 oblika četvrtine kruga, a potom u horizontalnu ravninu 100. Ono se produžuje u dio kruga koji formira udubljenje 102 pomaknuto u odnosu na prorez 94 u smjeru kraja 88 zatezne poluge. Na taj će način, tokom operacije povezivanja koja će biti kasnije opisana, rukavac 52 upravljačkog elementa 38 težiti da se osloni na udubljenje 102, tako da se izbjegne nepoželjno odvajanje zatezne poluge od ručke. Each of the notches 90, 92 consists of a vertical slot 94, the edge 96 of which is remote from the end 88 of the tension lever, and extends tangentially into the quarter-circle portion 98, and then into the horizontal plane 100. It extends into the portion of the circle that forms recess 102 offset relative to slot 94 in the direction of the end 88 of the tension lever. In this way, during the connection operation that will be described later, the sleeve 52 of the control element 38 will tend to rest on the recess 102, so as to avoid undesired separation of the tension lever from the handle.
Sa pozivom na slike 1 do 7C, biti će opisano povezivanje dva elementa cjevovoda pomoću naprijed opisanog uređaja. Pretpostavlja se da je element 2 nepokretan, i već povezan sa drugim elementima cjevovoda koji nisu prikazani. With reference to Figures 1 to 7C, the connection of two piping elements using the device described above will be described. It is assumed that element 2 is stationary, and already connected to other pipeline elements that are not shown.
Naprava 22 za pritezanje na početku se pričvrsti oko elementa 2, na unaprijed određenom rastojanju od njegovog kraja. Osnovna ploča 40 ručke 38 oslonjena je na nivou jedne od njenih površina 44, tako da su rukavac 52 ručke 38, i rukavac 30 naprave 22 za pritezanje, poravnati u odnosu na uzdužnu os elementa 2, pri čemu je rukavac 52 postavljen sa strane ravnog kraja. The tightening device 22 is initially attached around the element 2, at a predetermined distance from its end. The base plate 40 of the handle 38 is supported at the level of one of its surfaces 44, so that the sleeve 52 of the handle 38 and the sleeve 30 of the tightening device 22 are aligned with respect to the longitudinal axis of the element 2, whereby the sleeve 52 is placed on the side of the flat end .
Zatim se obje zatezne poluge 80 postavljaju na tijelo 58 oslone naprave 20, koja se postavlja na proširenje 8 elementa 4. U tom se cilju otvori 84 stavljaju na rukavce 62, a otvori 86 na rukavce 64. Na dijametralne rukavce 62 postavljaju se elementi za osiguranje, na primjer matice, koji nisu prikazani. Then both tension levers 80 are placed on the body 58 of the support device 20, which is placed on the extension 8 of the element 4. For this purpose, the openings 84 are placed on the sleeves 62, and the openings 86 on the sleeves 64. The securing elements are placed on the diametrical sleeves 62 , for example nuts, which are not shown.
Do tada je tijelo 58 naprave 20 postavljeno na dio vanjske površine proširenja 8 radi spajanja njihovih upora 18 i 59. U slučaju cjevovoda velikog promjera, kako je naprijed rečeno, na tijelo se pričvršćuje jedan komplementarni sektor, tako da oslona naprava obuhvaća cijeli obujam proširenja. Until then, the body 58 of the device 20 is placed on part of the outer surface of the extension 8 in order to connect their supports 18 and 59. In the case of large-diameter pipelines, as stated above, one complementary sector is attached to the body, so that the support device covers the entire volume of the extension.
Potom se element 4 približava elementu 2 pomoću neke dizalice, ili ručno ukoliko je manjih dimenzija, tako da rukavci 52 nalegnu na udubljenje 102 krajnjih ureza 92 obiju zateznih poluga 80, tako da se ravan kraj 6 centrira u ulaznoj prirubnici 9 proširenja 8 (slika 7A). Then the element 4 is brought closer to the element 2 using a crane, or by hand if it is of smaller dimensions, so that the sleeves 52 rest on the recess 102 of the end notches 92 of both tension levers 80, so that the flat end 6 is centered in the input flange 9 of the expansion 8 (Fig. 7A ).
Početni položaj naprave 22 za pritezanje na elementu 2 omogućuje da se zadovolje ova dva uvjeta. The initial position of the tightening device 22 on the element 2 enables these two conditions to be met.
U ovoj situaciji, obavezno će postojati odstupanje između uzdužnih osi elemenata 2 i 4, tj. između dvije krajnje vrijednosti definirane oslanjanjem rukavaca 64 na poprečne površine 104, 106 gornjih otvora 86 obiju zateznih poluga. In this situation, there will necessarily be a deviation between the longitudinal axes of elements 2 and 4, i.e. between the two end values defined by resting the sleeves 64 on the transverse surfaces 104, 106 of the upper openings 86 of both tension levers.
Opseg odstupanja perfektno je reguliran, a može se modificirati, u funkciji zapora koji postoji između gornjeg otvora 86 i rukavca 64, a time i međusobni položaj tih rukavaca i uvodnih otvora. Izum omogućuje da se tokom početne faze povezivanja utvrdi međusobni položaj između oba elementa cjevovoda približno jednak njihovom unaprijed utvrđenom međusobnom položaju. The extent of the deviation is perfectly regulated, and can be modified, as a function of the barrier that exists between the upper opening 86 and the sleeve 64, and thus the mutual position of these sleeves and the inlet openings. The invention makes it possible to establish, during the initial phase of connection, the mutual position between both pipeline elements approximately equal to their predetermined mutual position.
Posebno, prema slici 7A, tijelo 10 elementa 4 postavljeno je malo niže radi priključivanja zateznih poluga na rukavce, pa element 4 ima težnju da se zakrene pod djelovanjem vlastite mase. Gornji rukavac 64 obujmice 20 nasloniti će se na vertikalni zid 104 otvora 86 zatezne poluge postavljene uz stranu elementa 4. Na taj će način os tijela 10 biti ispod osi elementa 2, pa će između osi ta dva elementa biti kut α jednak, u ovom primjeru 2 °. In particular, according to Figure 7A, the body 10 of the element 4 is placed a little lower in order to connect the tension levers to the sleeves, so the element 4 has a tendency to rotate under the action of its own mass. The upper sleeve 64 of the clamp 20 will rest on the vertical wall 104 of the opening 86 of the tension lever placed next to the element 4. In this way, the axis of the body 10 will be below the axis of the element 2, so the angle α between the axes of these two elements will be equal, in this example 2 °.
Prema slici 7B, radnik zakreće šestostranu maticu za oko 30 ° u smjeru strelice F. Zatezna poluga se naginje u odnosu na horizontalu za kut αʹ, koji u ovom slučaju iznosi 2 °. Da bi se to ostvarilo, gornji otvor 86 zatezne poluge 80 okrene se također za isti kut αʹ oko donjeg otvora 84, a u smjeru elementa 4. According to Figure 7B, the worker rotates the hexagonal nut by about 30 ° in the direction of arrow F. The tension lever is tilted relative to the horizontal by an angle αʹ, which in this case is 2 °. To achieve this, the upper opening 86 of the tension lever 80 is also turned by the same angle αʹ around the lower opening 84, in the direction of element 4.
Moment izazvan masom elementa 4 zakreće taj element tako da gornji rukavac 64 obujmice 20 naliježe na sam zid 104 otvora 86. Element 4 perfektno je poravnat sa elementom 2. U ovom položaju ravni kraj elementa 2 prodro je u brtvilo 16 približno za polovinu njegove dužine. The moment caused by the mass of the element 4 rotates that element so that the upper sleeve 64 of the clamp 20 rests on the very wall 104 of the opening 86. The element 4 is perfectly aligned with the element 2. In this position, the flat end of the element 2 has penetrated the seal 16 for approximately half of its length.
Na slici 7C šestostrana matica 46 načinila je četvrtinu okreta u odnosu na svoj početni položaj. Zatezna poluga 80 odstupa od horizontale za kut α" koji je veći od kuta αʹ, a iznosi na primjer 4 °. Na analogni način se okreće gornji otvor 86 zatezne poluge za kut α" oko donjeg otvora 84, u odnosu na svoj početni položaj. In Figure 7C, hex nut 46 has made a quarter turn from its initial position. The tension lever 80 deviates from the horizontal by an angle α" which is greater than the angle αʹ, and is, for example, 4 °. In an analogous manner, the upper opening 86 of the tension lever rotates by an angle α" around the lower opening 84, in relation to its initial position.
Međutim, nasuprot prethodnim slikama, rukavac 64 naprave 20 za pritezanje više ne naliježe na zid 104. U stvari, brtvilo 16 od sada je u dodiru cjelom svojom unutrašnjom površinom sa ravnim krajem 6 elementa 2. Brtvilo 16 omogućava vođenje elementa 4, i kompenzira moment koji proizvodi njegova masa. Brtvilo 16 je to, a ne bočni zid 104 otvora, što sprečava zakretanje elementa 4 nadolje. However, in contrast to the previous figures, the sleeve 64 of the tightening device 20 no longer rests on the wall 104. In fact, the seal 16 is now in contact with its entire inner surface with the flat end 6 of the element 2. The seal 16 enables the guidance of the element 4, and compensates the torque produced by its mass. It is the seal 16, and not the side wall 104 of the opening, that prevents the element 4 from turning downwards.
U daljem toku operacija sklapanja, koje nisu prikazane, brtvilo nastavlja vršiti funkciju vodilice, tako da se element 4 praktično translacijski pomiče bez komponente zakretanja. In the further course of the assembly operations, which are not shown, the seal continues to perform the function of the guide, so that the element 4 practically moves translationally without the component of rotation.
Može se zaključiti da, u ovom slučaju, zapor izveden između rukavca 64 i gornjeg otvora 86 zatezne poluge omogućuje da se ta dva elementa pomiču bez zaglavljivanja. On omogućuje izjednačavanje njihovih pomaka, i to, dok brtvilo 16 vodi vanjski element 4, približno translacijskog pomaka u slučaju dodatnog rukavca, i translacijskog pomaka sa komponentom okretanja za otvor zatezne poluge. It can be concluded that, in this case, the stop provided between the sleeve 64 and the upper opening 86 of the tension lever allows these two elements to move without jamming. It enables the equalization of their displacements, and that, while the seal 16 guides the outer element 4, approximately the translational displacement in the case of the additional sleeve, and the translational displacement with the turning component for the opening of the tension lever.
Treba napomenuti da u ovom primjeru elementi 2 i 4 imaju neznatno međusobno odstupanje u početnoj fazi njihovog sklapanja (slika 7A). To im omogućuje da budu praktično poravnati, tako da se zakretanje zatezne poluge vrši u slijedećim fazama (slike 7B i 7C) koje su manje kritične u pogledu cjelovitosti brtvila, a posebno onda kada se, prema položaju sa slike 7B, brtvilo počinje jako sabijati, te omogućava funkciju vođenja elementa 4. It should be noted that in this example, elements 2 and 4 have a slight deviation from each other in the initial stage of their assembly (Figure 7A). This allows them to be practically aligned, so that the rotation of the tension lever is carried out in the following stages (Figures 7B and 7C) which are less critical in terms of the integrity of the seal, and especially when, according to the position of Figure 7B, the seal begins to compress strongly, and enables the function of guiding element 4.
Slijedeća faza sklapanja (nije prikazana) obuhvaća zakretanje osnovne ploče 40 upravljačkog elementa 38 do nalijeganja na rukavac 36, tako što će matica napraviti pola okretaja. Potom se rukavac 32 izvadi iz krajnjeg ureza 92 zatezne poluge 80, matica se zakrene za pola kruga u suprotnom smjeru, pa se rukavac umetne u drugi urez 90 zatezne poluge. Potom se matica 46 ponovo zakrene za pola okretaja u smjeru strelice F, tako da dovede do nalijeganja elementa 4 na krajnji dio elementa 2, na nivou upora 12 na dnu proširenja. The next stage of assembly (not shown) involves rotating the base plate 40 of the control element 38 until it abuts the sleeve 36, so that the nut makes a half turn. Then the sleeve 32 is removed from the end notch 92 of the tension lever 80, the nut is turned half a circle in the opposite direction, and the sleeve is inserted into the second notch 90 of the tension lever. Then the nut 46 is turned again by half a revolution in the direction of arrow F, so that it leads to the abutment of the element 4 on the end part of the element 2, at the level of the abutment 12 at the bottom of the extension.
Slika 8 prikazuje jednu varijantu kod koje vanjska površina proširenja 8 nema upor kao na slici 1, već ima približno konusni profil. Veza između takvog proširenja 8 i naprave 20 za pritezanje osigurana je posredstvom adapterskog prstena 108, načinjenog od materijala analognog materijalu naprave za pritezanje, i pričvršćenog na njoj. Ovaj prsten ima konusni unutrašnji profil koji odgovara vanjskom profilu proširenja, a vanjski profil prilagođen unutrašnjem profilu tijela 58. Figure 8 shows one variant where the outer surface of the extension 8 does not have a stop as in Figure 1, but has an approximately conical profile. The connection between such an extension 8 and the tightening device 20 is provided by means of an adapter ring 108, made of a material analogous to the material of the tightening device, and attached to it. This ring has a conical inner profile that corresponds to the outer profile of the extension, and the outer profile adapted to the inner profile of the body 58.
Uređaj za povezivanje prema izumu omogućuje ručno umetanje elemenata cjevovoda čiji nominalni promjer može dostići 300 mm. The connection device according to the invention enables the manual insertion of pipeline elements whose nominal diameter can reach 300 mm.
On naročito omogućuje postavljanje proširenja cijevi ili priključka, na primjer koljena, T-priključka ili L-priključka, na ravan kraj jedne cijevi. In particular, it allows fitting a pipe extension or fitting, for example an elbow, T-fitting or L-fitting, to the flat end of a pipe.
On također omogućuje povezivanje elemenata kanalizacije vrlo velikih dimenzija, kao što su lijevane cijevi dužine od više metara. It also enables the connection of sewerage elements of very large dimensions, such as cast pipes with a length of several meters.
