Abstract

The two half-shells(11,12) of the sleeve fitted over the oppositely lying pipe ends are braced on both sides by two sealing clamps(31-34) and in their final position a defined gap remains between the two clamps on the lower side and between the two clamps on the upper side. On the inside of the half-shells, on both sides of the inlaid sealing mats, clamping elements(42,44) are installed in a corresponding groove which is closed in relation to the planes of separation of the half-shells.

Description

Izum se sastoji od dvije poluljuske koje tvore spoj steznim naglavkom za pune cijevi, te takve, koje su sastavljene od dviju polucijevi, kao što su kabelske kanalne cijevi, reparaturne cijevi i tome slično, s jednom brtvenom podlogom između brtvene vanjske cijevne stijenke i unutarnje stijenke steznog naglavka, koja je pridržana u svojem krajnjem položaju sa zapornim klinovima. The invention consists of two half-shells that form a connection with a clamping head for full pipes, and such, which are composed of two half-pipes, such as cable channel pipes, repair pipes and the like, with one sealing pad between the sealing outer pipe wall and the inner wall clamping head, which is held in its final position with locking pins.

Ovakvi cijevni naglavci, koji se sastoje od poluljuski, već su poznati. Tako prikazuje DE 78 33 835 U1 jedan cijevni naglavak, koji odgovara glavnom pojmu patentnog zahtjeva 1, kod kojega je unesena viskozna brtvena masa u šupljinu stvorenu vanjskim promjerom cijevi i unutarnjim srednjim dijelom unutarnjeg promjera naglavka, kao i između dodirnih sudarnih mjesta obiju poluljuski. Such tube heads, which consist of half-shells, are already known. Thus, DE 78 33 835 U1 shows a tube cap, which corresponds to the main term of patent claim 1, where a viscous sealing compound is introduced into the cavity created by the outer diameter of the tube and the inner middle part of the inner diameter of the cap, as well as between the contact collision points of both half-shells.

Ovi cijevni naglavci su se pokazali u praksi, te su bili primjenjeni u velikom broju najviše za brtvenje kabelskih kanalnih cijevi. U posljednje vrijeme tehnologija polaganja kabelskih kanala potpuno se promijenila, utoliko da su se primjenjivala klizna ulja za uvlačenje kablova, koja su kemijski napadala brtvenu masu, tako da su je topila, te je stoga često veoma brzo dolazilo do propusnosti. Nadalje, pokazalo se da viskozitet primjenjenih brtvenih masa podliježe jakim kolebanjima kod ekstremnih temperatura, te su zbog toga bile premekane ili pretvrde. These pipe heads have proven themselves in practice, and were used in large numbers, mostly for sealing cable channel pipes. In recent times, the technology of laying cable channels has completely changed, to the extent that sliding oils were used for pulling in cables, which chemically attacked the sealing compound, so that they melted it, and therefore permeability often occurred very quickly. Furthermore, it was shown that the viscosity of the applied sealants was subject to strong fluctuations at extreme temperatures, and as a result they were too soft or too hard.

Iz EP 0650007 B1 postao je poznat jedan slijedeći cijevni naglavak, koji se sastoji od dvije poluljuske, a kojim su ti nedostaci uklonjeni. Prema tome uložena je uzdužno podijeljena brtvena podloga između vanjske cijevne stijenke, koju treba brtviti, i unutarnje stijenke cijevnog naglavka, pri čemu je ista zahvaćena u jednom utoru na obje poluljuske. From EP 0650007 B1, a following tubular head, which consists of two half-shells, has become known, and with which these defects have been removed. Accordingly, a longitudinally divided sealing pad is inserted between the outer pipe wall, which needs to be sealed, and the inner wall of the pipe head, whereby the same is caught in one groove on both half-shells.

Ovi poznati cijevni naglavci ipak trebaju biti poboljšani. Oni su doduše nepropusni, ali samo do jedne granice od oko 3 bara. To više ne zadovoljava u mnogim novim slučajevima primjene. These familiar tube headers still need to be improved. They are admittedly impermeable, but only up to a limit of about 3 bars. This is no longer satisfactory in many new application cases.

Daljnja značajka koju treba poboljšati je uzdužno prenošenje sile takvih naglavnih spojeva. Pokazalo se naime, kod današnjih novih postupaka, da se kablovi unose, pogotovo kablovi sa staklenim vlaknima velikih dužina, pod visokim tlakom u kabelske kanalne cijevi. Kod toga se može dogoditi, da se trebaju izvaditi iz naglavka, primjerice preko reparaturnog komada, stoga što njihova sposobnost uzdužnog prenošenja sile više ne zadovoljava. Ako je brtveno djelovanje nedovoljno, može pad tlaka prilikom unošenja kablova, čak sasvim spriječiti provedbu postupka, a osim toga u pogonskom stanju kod dubljih slojeva ili na vodenim terenima prodire voda u kanalsku cijev, a to ometa propisnu uporabu kabla. A further feature that needs to be improved is the longitudinal force transmission of such butt joints. It has been shown that, with today's new procedures, cables, especially cables with glass fibers of large lengths, are inserted under high pressure into the cable channel pipes. In this case, it may happen that they need to be removed from the head, for example via a repair piece, because their ability to transmit force longitudinally is no longer satisfactory. If the sealing effect is insufficient, a drop in pressure during the insertion of the cables can even completely prevent the procedure from being carried out, and in addition, water penetrates into the channel pipe in operating conditions at deeper layers or in watery areas, and this interferes with the proper use of the cable.

Ovaj izum ima rješenje za spomenuti problem. Izum, prema navedenim patentnim zahtjevima ima zadaću, da načini takav spoj cijevnim naglavkom, koji će imati poboljšanu nepropusnost do oko 10 bara, i da kod unošenja kablova visokim tlakom, ima posebnu mogućnost prenošenja uzdužne sile. This invention has a solution to the mentioned problem. The invention, according to the mentioned patent claims, has the task of making such a connection with a pipe head, which will have an improved impermeability up to about 10 bar, and that when introducing cables at high pressure, it has a special possibility of transmitting longitudinal force.

Postignute prednosti ovim izumom, posebno se očituju u tome, da je moguće, kroz povećan učinak brtvenja, opteretiti kabelsku cijev visokim tlakom, te time omogućiti moderan postupak, odnosno postupak ustrujavanja za kabel velike duljine sa istovremenim djelovanjem prenošenja uzdužne sile u području spoja cijevnim naglavkom, tako da je neželjeno izvlačenje cijevnih krajeva iz naglavka sa sigurnošću spriječeno. The advantages achieved by this invention are particularly evident in the fact that it is possible, through an increased sealing effect, to load the cable tube with high pressure, and thus enable a modern process, i.e. a flow-in process for a long cable with the simultaneous effect of transmitting longitudinal force in the area of the connection with the pipe head , so that the unwanted pulling out of the pipe ends from the nozzle is safely prevented.

Izum se pobliže pojašnjava na temelju jednog izvedbenog primjera, prikazanog na slijedećim slikama, gdje pokazuje: The invention is explained in more detail on the basis of one embodiment, shown in the following figures, where it shows:

Slika 4 perspektivni prikaz poluljuske naglavka, i Figure 4 is a perspective view of the half-shell of the cap, i

Slika 5 perspektivni prikaz zaporne kopče. Figure 5 is a perspective view of the locking clip.

Na slikama predočen cijevni stezni naglavak 1, sastoji se uglavnom od dvije poluljuske 11 i 12, dviju polovina brtvenih podloga 2a i 2b uloženih unutar naglavka, te četiri zaporne kopče 31, 32, 33 i 34, kao i od steznih elemenata 41, 42, 43 i 44. The tubular clamping head 1 shown in the pictures consists mainly of two half-shells 11 and 12, two halves of sealing pads 2a and 2b inserted inside the head, and four locking clips 31, 32, 33 and 34, as well as clamping elements 41, 42, 43 and 44.

Kao što je vidljivo iz Slike 1, obje poluljuske 11 i 12 cijevnog steznog naglavka 1, koje su međusobno pritegnute pomoću po dvije na njihovim gornjim i donjim polovinama nagnute zaporne kopče 31 i 32, odnosno 33 i 34, tako da je brtvena podloga 2 stisnuta između obje poluljuske 11 i 12. Kada su obje zaporne kopče 31, 32 odnosno 33, 34 dovedene u svoj krajnji položaj, tada ostaje između njih jedan aksijalni razmak od oko 25% od njihove odgovarajuće duljine L, kako bi se, u slučaju potrebe, mogle poduzeti korekcije pritisnog tlaka. Stezni elementi 41, 42, 43, 44 za postizanje prenosivosti sile u uzdužnom smjeru spoja steznim naglavkom, smješteni su u gornjem dijelu nasuprot ruba, odnosno razdjelne ravnine 61-62 poluljuski 11, 12, zatvorenog utora 51 odnosno 52. As can be seen from Figure 1, both half-shells 11 and 12 of the tubular clamping head 1, which are mutually tightened by means of two inclined locking clips 31 and 32, respectively 33 and 34 on their upper and lower halves, so that the sealing pad 2 is compressed between both half-shells 11 and 12. When both locking clips 31, 32 and 33, 34 are brought to their end position, then an axial distance of about 25% of their corresponding length L remains between them, so that, in case of need, could take pressure corrections. Clamping elements 41, 42, 43, 44 for achieving force transferability in the longitudinal direction of the joint with a clamping head, are located in the upper part opposite the edge, that is, the dividing plane 61-62 of the half-shells 11, 12, of the closed groove 51 and 52, respectively.

Slika 2 prikazuje cijevni stezni naglavak u djelomičnom presjeku, pri čemu su obje donje zaporne kopče 31 i 32, već dovedene u svoj krajnji položaj, dok se gornje zaporne kopče 33 i 34 naguraju u smjeru strelice na cijevni naglavak 1. Figure 2 shows the tubular clamping head in a partial section, where both lower locking clips 31 and 32 are already brought to their end position, while the upper locking clips 33 and 34 are pushed in the direction of the arrow onto the tubular head 1.

Iz djelomičnog presjeka Slike 3, vidljiv je siguran na tlak i silu prenosiv spoj steznim naglavkom, kod kojega su oba dva cijevna završetka 6 i 7 unutar tijela naglavka 1 međusobno spojeni nepropusno i tako da uzdužno prenose silu. Pri tome brtvenje slijedi preko aksijalno razdijeljenih brtvenih podloga 2a, 2b, koje su, kao što se vidi iz Slike 4, uložene u razdjelnoj ravnini 61, 62 poluljuski u aksijalno smještenom utoru 63 i/ili uložene u udubljenom području 21, 22. Na Slici 3 je sa A označen određeni razmak između zapornih kopči 31 i 32, oko 25% njihove duljine L, u njihovom krajnjem položaju. Zaporne kopče 31 i 32 su prednosno proizvedene od pojačane umjetne tvari, te su predviđene izvana sa osloncima 37. From the partial section of Figure 3, a pressure- and force-transmissible connection with a clamping head can be seen, in which both pipe ends 6 and 7 inside the body of the head 1 are connected to each other tightly and so that they transmit force longitudinally. In this case, the sealing takes place via the axially divided sealing pads 2a, 2b, which, as can be seen from Figure 4, are inserted in the dividing plane 61, 62 of the half-shell in the axially located groove 63 and/or inserted in the recessed area 21, 22. In Fig. 3, a certain distance between the locking clips 31 and 32, about 25% of their length L, in their final position is marked with A. The locking clips 31 and 32 are preferably made of reinforced synthetic material, and are provided externally with supports 37.

Slika 5 prikazuje gornju površinu mosnog područja 35, zapornih kopči 31, 32, 33, 34, koja je okrenuta prema tijelu naglavka 1. Ova gornja površina je opremljena kliznom plohom 36, kako bi se olakšalo polaganje zapornih kopči na tijelo naglavka. Fig. 5 shows the upper surface of the bridge area 35 of the locking clips 31, 32, 33, 34, which faces the head body 1. This upper surface is equipped with a sliding surface 36, to facilitate the laying of the locking clips on the head body.
