Abstract
Rýchlouzáver hrdla nádob, najma tlakových pozostáva z válcovitého telesa opatřeného na jednom konci tesniacou přírubou a na druhom konci opěrnou plochou pre excenter spojený s posuvným ťahadlom, usporiadaným súosovo s telesom rýchlouzáveru. Riešeným problémom je skrátenie manipulačných časov a možnost jeho použitia i pre vačšie tlaky v nádobě. To sa dosahuje tým, že ťahadlo (11) je na svojom druhom konci opatřené čapom (15) v podobě zapustenej skrutkovej hlavy, na ktorého kuželová plochu (H6) sú opřete upínacle segmenty (17), opatřené na ich obvode zásuvnou kuželovou plochou (18) a výsuvnou kuželovou plochou (19) ,a na ich priláhlom konci k tesniacej přírubě (5) vnútornou vodiacou plochou (20), vonkajšou vodiacou plochou (21), ako aj čelnou dosadacou plochou, či britom (2:2) k opěrnému krúžku (23), opretému o pružnú vložku (24) vo vybraní (25) vnútorného dielu (4) válcovitého telesa (1).A quick-release closure for the neck of a vessel, especially a pressure vessel, consists of a cylindrical body provided with a sealing flange at one end and a support surface for an eccentric connected to a sliding rod, arranged coaxially with the quick-release closure body, at the other end. The problem solved is to shorten handling times and to enable its use even for higher pressures in the vessel. This is achieved by the fact that the tie rod (11) is provided at its other end with a pin (15) in the form of a recessed screw head, on whose conical surface (H6) the clamping segments (17) are supported, provided on their periphery with a plug-in conical surface (18) and a retractable conical surface (19), and at their end adjacent to the sealing flange (5) with an inner guide surface (20), an outer guide surface (21), as well as a frontal contact surface, or edge (2:2) for the support ring (23), supported by a flexible insert (24) in the recess (25) of the inner part (4) of the cylindrical body (1).
Description
Vynález sa týk-a rýchlouzáveru hrdla nádob, najma tlakových, pozostávajúceho z válcovitého telesa, opatřeného na jednom konci tesniacou přírubou a na druhom konci opěrnou plochou pre excenter spojený s posuvným ťahadlom, súosovo usporiadaným v telese rýchlouzáveru.SUMMARY OF THE INVENTION The present invention relates to a quick-closing cap of containers, in particular pressurized, consisting of a cylindrical body provided with a sealing flange at one end and an eccentric abutment surface connected to a sliding puller coaxially arranged in the fastener body.
Podía súčasného stavu techniky bývajú -hrd-lá nádob, pokial' majú vonkajší či vnútorný závit, u-zatvárané maticovou zátkou. Okrem toho sú známe aj rýchlouzávery vytvořené z excentra, opretého o prítlačnú prírubu, ktorá je -opretá o čelnú plochu příslušného- hrdla. Medzi přítlačnou přírubou a hlavicou ťah-a-dla je ivložená najmenej jedna gumená vložka, ktorá pri uzatv-orení excentra je stláč-a-ná v axiálnom smere, čím vyvíja radiálny tlak na vnútornú stenu hrdla nádoby, s ktorou vytvára třecí spoj. Nevýhodou takéhoto riešenia je, že rýchlouzáver možno použiť len na ipomerne -malé tlaky.According to the state of the art, the containers are closed with a nut plug when they have an external or internal thread. In addition, quick-closing devices made of an eccentric, supported on a pressure flange, are also known, which are supported against the face of the respective neck. At least one rubber liner is inserted between the thrust flange and the thrust head, which is compressed in the axial direction when the eccentric is closed, thereby exerting radial pressure on the inner wall of the throat with which it forms the frictional joint. A disadvantage of such a solution is that the fastener can only be used for moderately low pressures.
Podstata vynálezu spočívá v tom, že ťahadloi je n-a svojom druhom konci opatřené čapom v podobě zapustenej skrutkovej hlavy, na ktorého kuželo-vú plochu sú opreté upínácie segmenty, -opatřené na ich obvode zásuvnou kuželovou plochou a výsuvnou kuželovou ploehou a n-a ich prilahlom konci k tesniacej prírube vnútornou vodiacou plochou, vonkajšou vodiacou plochou, ako -aj čelnou dosa-da-cou plochou, či britom k opernému krúžku, opretému -o pružnú vložku vo vybraní vnútorného dielu válcovitého telesa. Výhodou rýchlouzáveru hrdla nádob podlá -vynálezu, okrem toh-o, že si vyžaduje minimálně manipulačně časy je, že ho možno použit pre vyššie tlaky, pričom možno nastavovat aj prítlačnú silu a rýchlouzávery jednoducho prisposobiť roznym dížkam hrdla nádoby. Příklad vyhotovenia rýchlouzáveru podlá vynálezu je znázorněný na výkrese, na ktorom je tento nakreslený v nárysnom řeze. Rýchlouzáver pozostáva z válcovitého telesa 1, tvořeného prvým vonkajším maticovým dielom 2 a druhým vonkajším maticovým dielom 3, ktoré obklopujú závitovú časť vnútorného dielu 4 válcovitého telesa 1. Na svojom vyčnievajúcom konci je vnútor- ný diel 4 válcovitého telesa 1 opatřený tvarovanou tesniacou přírubou 5 s tesniacim krúžkom 6, zatial čo na druhom konci válcovitého -telesa 1, t. j. na čele jeho vonkajšieho- maticového dielu 2, je opěrná plocha 7 pře excenter 8, spojený pomocou čapu 9 s okom 10 fahadla 11.The essence of the invention is that the drawbar is provided at its second end with a pin in the form of a countersunk screw head, to which the tapered surface is supported by clamping segments, provided at their periphery with a plug-in conical surface and an extendable conical surface. a sealing flange with an inner guide surface, an outer guide surface, such as a front face, or an abutment ring, supported by a resilient insert in a recess of the inner portion of the cylindrical body. The advantage of the container neck fastener according to the invention, except that it requires at least handling times, is that it can be used for higher pressures, while the pressing force can also be adjusted and the fasteners can be easily adjusted to the different parts of the container neck. An example of an embodiment of a quick-closing device according to the invention is shown in the drawing in which it is drawn in a front view. The fastener consists of a cylindrical body 1 formed by a first outer nut part 2 and a second outer nut part 3 which surround the threaded part of the inner part 4 of the cylindrical body 1. At its protruding end the inner part 4 of the cylindrical body 1 is provided with a molded sealing flange 5 s with a sealing ring 6, while at the other end of the cylindrical body 1, ie at the face of its outer nut part 2, the support surface 7 is connected to the eyelet 10 by means of a pin 9 with the eye 10 of the mower 11.
Tahadlo 11 je vložené súosovo do telesa 1 rýchlouzáveru, a to prostrédníctvom vymedzovacieho- puzdra 12 a tlačnej pružiny 13, -opretej o dorazovú maticu 14. Na svojom druhom konci je ťahadlo 11 opatřené čapom 15 v podolbe zapustenej skrutkovej hlavy, na ktorého kuželovú plochu 16 sú opre-té upínácie segmenty 17. Tieto sú na ich -obvode opatřené zásuvnou kuželovou p-lochou 18 a výsuvnou kuželovou plochou 19 a na ich prilahlom konci k tesniacej prírube 5 vnútornou vodiacou plochou 20, vonkajšou vodiacou plochou 21, ak-o aj čelným dosadacím britom 22 k -opěrnému krúžku 23, opretému o pružnú, v danom případe gumovú vložku 24 o vybraní 25 vnútorného dielu 4 válcovitého telesa 1. Tento vnútorný diel 4 je -okrem toho opatřený prstencovou drážkou, v ktorej je umiestnený menší tesniaci krúžok 26.The puller 11 is inserted coaxially into the fastener body 1 by means of a spacer sleeve 12 and a compression spring 13 supported against the stop nut 14. At its other end, there is a puller 11 provided with a pin 15 in the recess of the countersunk head to whose conical surface 16 they are support clamping segments 17. These are provided on their periphery with a plug-in conical p-loch 18 and an extending conical surface 19 and at their adjacent end with a sealing flange 5 with an inner guide surface 20, an outer guide surface 21, both front and rear. with an abutment lip 22 on the abutment ring 23, supported by a resilient, in this case rubber insert 24, a recess 25 of the inner portion 4 of the cylindrical body 1. This inner portion 4 is further provided with an annular groove in which a smaller sealing ring 26 is disposed.
Keď je excenter 8 v uvolne-nej polohe, vysunie sa tah-adlo 11, upínácie segmenty 17 sa pomocou pružného krúžku 27 stiahnu, čo umožní zasunúť činné časti rýchlouzáveru do hrdla tlakovej nádoby 28 až potial, ked sa tesniaci krúžok 6 oprie o čelo hrdla nádoby 28. Potom sa pák-a 29 excentra 8 vychýlí smerom k uzavretej polohe, pričom sa upínácie segmenty 17 roztiahnu a svojimi vysúvacími kuželovými plochami 19, ktoré v roztvorenom stave -majú funk-ciu kotviacich ploch, sa zachytia o vnútornú hranu hrdla nádoby 28.When the eccentric 8 is in the relaxed position, the pull-off member 11 is extended, the clamping segments 17 are retracted by means of the elastic ring 27, allowing the active parts of the quick-closing device to be inserted into the neck of the pressure vessel 28 until the sealing ring 6 rests against the neck of the neck of the container 28. Thereafter, the cams 29 and 29 of the eccentric 8 are deflected towards the closed position, whereby the clamping segments 17 extend and engage the inner edge of the container neck 28 with their extension conical surfaces 19, which in the opened state have anchoring surfaces. .
Po- -dokončení uzatváracieho pohybu pákou 29 sa stlačí aj tesniaci krúžok 6, čím sa utes-ní 'hrdlo nádoby 28 voči tesniacej prírube 5. Menší tesniaci krúžok 26 zabraňuje prenikaniu tlakového- média centrálnym o-tvorom vo vnútornom dieli 4 válcovitého telesa 1. Změnou polohy vonkajších maticových dielov· 2, 3 voči vnútornému dielu 4 teles-a 1 možno nastavovat prítlačnú silu, ako aj meniť, alebo prisposobiť rýchlouzáver roznym dlžkam 30 hrdla nádoby 28.Also, the sealing ring 6 is compressed by the lever 29 to complete the closing movement, thereby sealing the neck of the container 28 relative to the sealing flange 5. The smaller sealing ring 26 prevents penetration of the pressurized medium through the central part in the inner part 4 of the cylindrical body 1. By varying the position of the outer nut parts 2, 3 with respect to the inner part 4 of the bodies 1 and 1, it is possible to adjust the pressing force as well as to change or adapt the quick release means 30 to the container neck 28.
