Description

Pronalazak se odnosi na zasun s kugličnim ventilom. Takvi zasuni se između ostalog koriste kod takozvanih kombiniranih kućnih instalacija. Na DE 296 18 605 U1 se upućuje samo kao primjer. The invention relates to a latch with a ball valve. Such latches are used, among other things, in so-called combined home installations. Reference is made to DE 296 18 605 U1 by way of example only.

Zasuni spomenute vrste koriste se posebice u cjevovodima, kojima se gradski plin uvodi u zgradu. Pri tome je sigurnost pravilo broj jedan. Zbog toga su zasuni ove vrste i općenito opremljeni sigurnosnim zaporima, koji jamče brzo zatvaranje, npr. kod nastanka visoke temperature. Valves of the mentioned type are used especially in the pipelines, through which city gas is introduced into the building. Safety is the number one rule. For this reason, latches of this type are generally equipped with safety locks, which guarantee quick closing, e.g. in case of high temperature.

Dakle, sigurnosni uređaj mora ispunjavati najstrože zahtjeve. Tijekom rada ne smije izgubiti svoju sposobnost, da u slučaju nužde brzo i sigurno zatvara. Nadalje, pogonsko stanje zasuna mora odmah i lako biti uočljivo izvana, tj. mora biti prepoznatljivo, da li je sigurnosni uređaj reagirao ili nije. Bez obzira na stanje sigurnosnog uređaja, čunj ventila se mora dati uključivati i isključivati ručnom polugom. Nadalje, sigurnosni se uređaj nakon izvršenja svoje funkcije mora dati ponovo izoštriti, čim je opasnost uklonjenja, dakle primjerice djelovanje privremene visoke temperature. Therefore, the safety device must meet the strictest requirements. During operation, it must not lose its ability to close quickly and safely in case of emergency. Furthermore, the operating state of the bolt must be immediately and easily visible from the outside, i.e. it must be recognizable whether the safety device has reacted or not. Regardless of the state of the safety device, the valve cone must be able to be turned on and off with a manual lever. Furthermore, after the performance of its function, the safety device must be allowed to be sharpened again, as soon as the danger of its removal, i.e. the effect of temporary high temperature, for example.

Poznati zasuni iziskuju izvjesno poboljšanje. Posebice kod zasuna prema DE 296 18 605 U1 postoji nedostatak, što se predviđeni osigurač s rastalnim lemom, nalazi u protočnom kanalu zasuna. Ovdje naime može nastupiti slijedeće: Known latches require some improvement. Especially with the latch according to DE 296 18 605 U1, there is a disadvantage, that the provided fusible link fuse is located in the flow channel of the latch. The following can occur here:

medij koji se nalazi u cjevovodu i koji prolazi kroz zasun je doduše razmjerno hladan, međutim okolina je topla ili vruća. Zbog činjenice, da se osigurač s rastalnim lemom nalazi unutar protočnog kanala, ne dolazi do taljenja rastalnog lema, tako da sigurnosni zapor ne može izvršiti svoju funkciju. Nepovoljno je i to, ako se unutar protočnog kanala nalaze opruge ili ostali inače osjetljivi dijelovi, koji zbog prirode transportiranog medija, mogu naginjati koroziji. the medium that is in the pipeline and that passes through the valve is admittedly relatively cold, but the environment is warm or hot. Due to the fact that the fuse with melting solder is located inside the flow channel, melting of the melting solder does not occur, so the safety lock cannot perform its function. It is also unfavorable if there are springs or other otherwise sensitive parts inside the flow channel, which, due to the nature of the transported medium, may be prone to corrosion.

Pronalazak se dakle temelji na zadaći, da se zasun spomenute vrste izvede tako, da nudi još veću sigurnost, da je otporniji na smetnje, da je lako s njime upravljati i da je stanje sigurnosnog uređaja lako uočljivo izvana, te da se sigurnosni uređaj nakon nastanka slučaja opasnosti, kao i nakon uklanjanja procesa koji ga je izazvao (primjerice djelovanje visoke temperature) ponovo može fino izoštriti. The invention is therefore based on the task of making a latch of the mentioned type in such a way that it offers even greater security, is more resistant to interference, is easy to operate and that the state of the security device is easily visible from the outside, and that the security device after its creation in case of danger, as well as after removing the process that caused it (for example, the effect of high temperature), it can fine-tune again.

Ova se zadaća rješava preko karakteristika iz podatka 1. This task is solved using the characteristics from data 1.

Važna prednost ovdje je ta, što se pridržni uređaj, koji sigurnosni zapor drži u otvorenom stanju, nalazi na mjestu, koje je lako pristupačno izvana. An important advantage here is that the holding device, which holds the safety lock in the open state, is located in a place that is easily accessible from the outside.

Pronalazak se pobliže objašnjava na temelju crteža. U njemu je pojedinačno prikazano slijedeće: The invention is explained in more detail on the basis of the drawings. It shows the following individually:

Slika 6 prikazuje peti izvedbeni oblik zasuna iz pronalaska Figure 6 shows the fifth embodiment of the latch from the invention

Kako je vidljivo sa slika, zasun koji je na njima prikazan, ima kućište 1. Kućište uključuje čunj kugličnog ventila 1.1. On ima priključni nastavak 1.2 i priključni nastavak 1.3, zatim ležajni nastavak 1.4 kao i upravljačku polugu 1.5 As can be seen from the pictures, the latch that is shown in them has a housing 1. The housing includes the cone of the ball valve 1.1. It has a connection extension 1.2 and a connection extension 1.3, then a bearing extension 1.4 as well as a control lever 1.5

Zaporna jedinica 2 obuhvaća poteznu šipku 2.1 i zaporno tijelo 2.2. The locking unit 2 includes the pull rod 2.1 and the locking body 2.2.

Ono radi zajedno sa sjedištem 1.6, koje je sastavni dio priključnog nastavka 1.3. Ležajni nastavak 1.4 uključuje ležajni tuljak 1.7. U ležajnom tuljku 1.7 se nalazi zaporna opruga 3. Ona nastoji, poteznu šipku 2.1 sa zapornim tijelom 2.2 na crtežu pokretati udesno. It works together with the seat 1.6, which is an integral part of the connecting extension 1.3. The bearing extension 1.4 includes the bearing sleeve 1.7. There is a locking spring 3 in the bearing sleeve 1.7. It tries to move the pull rod 2.1 with the locking body 2.2 in the drawing to the right.

U priključni nastavak 1.3 je ugrađen O-prsten. On ima slijedeću zadaću: prilikom zatvaranja zapornog tijela 2.2 stvara se nepropusni spoj metal-metal između zapornog tijela 2.2 i sjedišta 1.6. Ujedno se O-prsten 1.8 potiskuje ustranu. An O-ring is installed in the connection extension 1.3. It has the following task: when closing the locking body 2.2, an airtight metal-to-metal connection is created between the locking body 2.2 and the seat 1.6. At the same time, the O-ring 1.8 is pushed to the side.

Kod postizanja nepropusnog sastavljanja metala djeluje i O-prsten 1.8 i naslanja se pod niskim prednaponom na površinu plašta zapornog tijela 2.2. The O-ring 1.8 is also effective when achieving an airtight assembly of the metal and rests under a low preload on the surface of the casing of the shutter body 2.2.

Razumije se, da zaporno tijelo 2.2 ne mora bezuvjetno imati kuglični oblik, kako je ovdje prikazano, nego može imati i drugačiji. On može primjerice biti izveden kao kružna pločica, kod koje se srednja os slaže sa smjerom zatvaranja. It is understood that the closing body 2.2 does not necessarily have to have a spherical shape, as shown here, but can also have a different one. It can, for example, be made as a circular plate, where the middle axis coincides with the closing direction.

Desni kraj potezne šipke 2.1 je izveden u obliku klipa -klip 2.3. Vidi se čep 4. On se sastoji od lako rastaljivog metala, primjerice wood-metala. Čep 4 je uključen u prostor, koji određuju klip 2.3, ležajni tuljak 1.7, kao i pridržni svornjak 6. The right end of the pull rod 2.1 is made in the form of a piston - piston 2.3. You can see plug 4. It consists of an easily melting metal, for example wood-metal. The plug 4 is included in the space defined by the piston 2.3, the bearing sleeve 1.7, as well as the retaining bolt 6.

Pridržni svornjak 6 ima kanal 6.1. Kod nastanka visoke temperature, tali se čep 4. Rastaljeni metal izlazi kroz kanal 6.1 prema van i ujedno prema van potiskuje indikator u boji 1, tako da je dotično pogonsko stanje lako prepoznatljivo. Klip 2.3 je opremljen s dva O-prstena, koji naliježu u žlijebove 2.3.1 i 2.3.2. Time se stvara nepropustan spoj prema unutrašnjosti kućišta. Retaining bolt 6 has channel 6.1. When a high temperature occurs, the plug 4 melts. The molten metal exits through the channel 6.1 to the outside and at the same time pushes the color indicator 1 to the outside, so that the operating state in question is easily recognizable. Piston 2.3 is equipped with two O-rings, which fit into grooves 2.3.1 and 2.3.2. This creates a leak-proof connection to the inside of the housing.

Navedeni čep 6 ima vanjski navoj kao i unutarnji šesterobrid. Said plug 6 has an external thread as well as an internal hexagon.

Čep od taljivog metala 4 može u potpunosti i izostati. Umjesto njega mogao bi doći primjerice plastični čep, koji se također tali pri nastanku visoke temperature. The fusible metal plug 4 can be completely absent. It could be replaced by, for example, a plastic cap, which also melts when high temperatures occur.

Izvedbeni oblik zasuna iz pronalaska, koji je prikazan na slici 4, ima većinom one elemente, koji su sadržani i u prethodnom izvedbenom obliku. Ležajni tuljak 1.7 je međutim nešto drugačije oblikovan. Ona naime na svom vanjskom završetku ima grijaći element 8. On je uključen u čep 4 od wood-metala i nosi kutni utikač 8.1. Utikač je preko kabela 8.2 priključen na uređaj za daljinsko upravljanje, koji ovdje nije prikazan. Grijaći element, odn. njegov utikač, nosi pridržna matica 9. Ležajni tuljak 1.7 ima ispusni provrt 1.7.1. Kroz njega u određenom slučaju može izlaziti wood-metal. The embodiment of the latch from the invention, which is shown in Figure 4, has mostly those elements that are included in the previous embodiment. The bearing sleeve 1.7, however, is shaped somewhat differently. Namely, it has a heating element 8 on its outer end. It is included in the plug 4 made of wood-metal and carries an angle plug 8.1. The plug is connected via cable 8.2 to the remote control device, which is not shown here. Heating element, or its plug is supported by a retaining nut 9. The bearing sleeve 1.7 has a discharge bore 1.7.1. Wood-metal can come out through it in certain cases.

Ovim izvedbenim oblikom je moguće, daljinski aktivirati grijaći element 8, tako da on wood-metal dovede do taljenja, i da metal može izlaziti kroz provrt 1.7.1 ili drugim putem. Klip 2.3 potisne šipke 2.1 kreće se zatim pod tlakom zaporne opruge 2 udesno, tako da se zaporno tijelo 2.2 oslanja na sjedište 1.6. Čak i ovdje ponovo zajednički djeluju nepropusni spoj metal-metal, formiran od zapornog tijela 2.2 i sjedišta 1.6, kao i nepropusni spoj metal-guma, formiran od zapornog tijela 2.2 i O-prstena 1.8. With this embodiment, it is possible to remotely activate the heating element 8, so that it causes the wood-metal to melt, and the metal can exit through the hole 1.7.1 or another way. The piston 2.3 of the push rod 2.1 then moves under the pressure of the stop spring 2 to the right, so that the stop body 2.2 rests on the seat 1.6. Even here, the metal-to-metal tight joint, formed by the locking body 2.2 and the seat 1.6, as well as the metal-to-rubber tight joint, formed by the locking body 2.2 and the O-ring 1.8, work together.

Izvedbeni oblik prema slici 5 predviđa mogućnost daljinskog upravljanja sigurnosnog zapora. Umjesto grijaćeg elementa 8 na slici 4, sada je predviđeno mehaničko uključivanje. Ponovo se prepoznaje čep 4 od lako taljivog metala. Nadalje, u ležajnom tuljku 1.7 na njegovom vanjskom završetku se nalazi pridržni svornjak 6. The embodiment according to Figure 5 foresees the possibility of remote control of the safety lock. Instead of the heating element 8 in Figure 4, a mechanical switch is now provided. Plug 4 made of easily fusible metal is recognized again. Furthermore, in the bearing sleeve 1.7, there is a retaining bolt 6 at its outer end.

Kako se vidi dalje, na ležajni tuljak 1.7 je navijen regulacijski prsten 10, kao i matica 11. Regulacijski prsten 10 nosi fazonski element 12 za Bowdenovu povlaku. Na njemu je prepoznatljiv zatik 13. Zatik 13 zahvaća preko provrta u ležajni tuljak 1.7 i u žlijeb prstena 6.2 na pridržnom svornjaku 6. Nadalje, vidljiva je kapica 14. Ona se sastoji od plastike i obuhvaća maticu 11. As can be seen below, the regulating ring 10 is wound on the bearing sleeve 1.7, as well as the nut 11. The regulating ring 10 carries the phase element 12 for the Bowden pull. There is a recognizable pin 13 on it. Pin 13 engages through the bore in the bearing sleeve 1.7 and in the groove of the ring 6.2 on the retaining bolt 6. Furthermore, the cap 14 is visible. It consists of plastic and includes the nut 11.

U normalnom stanju, u kojem je sigurnosni zapor otvoren, t.j. u kojem je zaporno tijelo 2.2 podignuto sa sjedišta 1.5, zatik 13 ulazi u žlijeb prstena 6.2. In the normal state, in which the safety lock is open, i.e. in which the locking body 2.2 is raised from the seat 1.5, the pin 13 enters the groove of the ring 6.2.

Ako nastupi sigurnosni slučaj, tada se tali wood-metal čepa 4. Kroz provrt 6.1 dolazi u pridržni svornjak 6, gledajući na slici udesno otkida plastičnu kapicu 14 i izlazi van. Alternativno, plastična bi kapica mogla imati i odgovarajući provrt. If a safety event occurs, then the wood-metal plug 4 melts. Through the hole 6.1 it enters the retaining bolt 6, looking at the picture to the right it tears off the plastic cap 14 and comes out. Alternatively, the plastic cap could also have a corresponding bore.

Ali, sigurnosnim zaporom se može upravljati i pomoću spomenute Bowdenove povlake. U tu svrhu se zatik 13 izvlači iz žlijeba prstena 6.2, tako da sila zaporne opruge 3 potiskuje klip 2.3 potezne šipke 2.1 udesno i time zaporno tijelo 2.2 dovodi do zatvaranja. But the safety lock can also be operated using the mentioned Bowden pull. For this purpose, the pin 13 is pulled out of the groove of the ring 6.2, so that the force of the locking spring 3 pushes the piston 2.3 of the pull rod 2.1 to the right and thus the locking body 2.2 closes.

Prednosti pronalaska su u slijedećem: The advantages of the invention are as follows:

Sigurnosni osjetljivi dijelovi, tj. posebno čep od lako rastaljivog materijala - bila to plastika ili lako taljivi metal - nalaze se izvan puta strujanja medija, koji se može zatvoriti zasunom. On je na taj način zaštićen i reagira samo na onu toplinu, koja se nalazi izvan medija. Safety-sensitive parts, i.e. especially the plug made of easily melting material - be it plastic or easily melting metal - are located outside the medium flow path, which can be closed with a latch. It is thus protected and reacts only to that heat, which is outside the medium.

Osim toga, zasun je vrlo jednostavan u montaži. In addition, the latch is very easy to assemble.

Nadalje, dotično stanje čitavog zasuna može se vrlo brzo i pouzdano prepoznati izvana. Također se nakon nastupanja sigurnosnog slučaja i uklanjanja okolnosti koja ga je izazvala, sigurnosna naprava se ponovo može lako i brzo izoštriti. Za to se naime treba samo umetnuti taljivi čep 4, što se može obaviti bez velike demontaže. Furthermore, the relevant state of the entire latch can be recognized from the outside very quickly and reliably. Also, after the occurrence of a safety event and removal of the circumstances that caused it, the safety device can be easily and quickly sharpened again. For this, you only need to insert the fusible plug 4, which can be done without extensive disassembly.
