Description
Vynález se týká konstrukčního provedení koncovky hadic, které umožňuje opakovaně její montážní a demontážní práce.The invention relates to a construction of a hose fitting which permits repeated assembly and disassembly work.
Pneumatické a hydraulické systémy zařízení jsou kromě jiných prostředků opatřeny hadicemi, které dopravuji tlakové medium do jeho jednotlivých částí. Konce hadic napojených na tyto části jsou opatřeny koncovkami, zaručujícími jednak vlastní spojení, jednak nepropustnost tlakového media v místech spojů. Koncovky jsou s hadicemi pevně spojeny a nelze, je z jejich konců bez zničení sejmout. V případech, je-li nutno hadici vyměnit za novou a není-li náhradní s příslušnou koncovkou k dispozici, jsou zařízení vyřazena z provozu.The pneumatic and hydraulic systems of the device are, among other means, provided with hoses which convey the pressure medium to its individual parts. The ends of the hoses connected to these parts are provided with terminals guaranteeing both the actual connection and the impermeability of the pressure medium at the joints. The terminals are firmly connected to the hoses and cannot be removed from their ends without destroying them. If the hose needs to be replaced with a new hose and a replacement with the corresponding fitting is not available, the devices are taken out of service.
Dosavadní konstrukce koncovek, kterých se používá jak pro nízké, tak i vysoké tlaky, sestávají z tělesa, převlečné matice a plechového pláště. Těleso je v podstatě válcovitého tvaru, opatřené v ose průběžným otvorem. Jedním koncem je uloženo v otvoru hadice, zatímco na druhém protilehlém konci, přesahujícím hadici, je opatřeno těsnícím kuželem. Těsnící kužel je uložen v převlečné matici, sloužící pro připojení k příslušné části zařízení. Plechový plášt je navlečen na povrchu hadice v místech vloženého tělesa. Po navlečení se v plechovém plášti provedou prolisy, jimiž se celé uspořádání koncovky na hadici zpevní ne- . rozebíratelným spojením.Existing terminal designs, which are used for both low and high pressures, consist of a body, a cap nut and a sheet metal sheath. The body is substantially cylindrical in shape, provided with an axial through hole. One end is received in the opening of the hose, while at the other opposite end, overhanging the hose, is provided with a sealing cone. The sealing cone is housed in a union nut for connection to the respective part of the device. The sheet metal sheath is threaded on the surface of the hose at the points of the intermediate body. After threading, embossments are made in the sheet metal sheath to reinforce the entire arrangement of the end piece on the hose. removable connection.
I když koncovky uvedeného provedení a v podstatě jemu podobných alternativ se běžně používají, stává se při běžné praxi, že v případě nutné výměny hadice není připravena náhradní, kterou by bylo možno použít· namísto původní. Tím je zařízení vyřazeno z provozu až do té doby, než je obstarána nová. Poškozená hadice se již neopravuje a vyhazuje se včetně koncovek. Taková výměna je však velmi neekonomická, poněvadž ve většině případechAlthough the terminals of the embodiment and the substantially similar alternatives are commonly used, it is common practice that, in the event of a need to replace the hose, a replacement is not prepared to be used instead of the original one. This puts the device out of service until a new one is acquired. Damaged hose is no longer repaired and is discarded including the fittings. However, such an exchange is very uneconomical, as in most cases
232 894 je jedna koncovka dobrá a po příslušné opravě v místech druhé koncovky bý bylo možné ještě hadici dále použít.232 894 is one ending good and after proper repair at the other end it was possible to use the hose again.
Nedostatky dosavadních provedení koncovek odstraňuje koncovka hadic podle tohoto vynálezu, jehož podstata spočívá v tom, že těsnící kuželka je druhým koncem uložená v tělese koncovky, například v její hlavě spojené se stopkou, opatřené jednak závitovou částí přecházející v kužel pro uložení hadice, rozšiřující se směrtom k čelu stopky, jednak průchozím otvorem navazujícím na průchozí otvor těsnicí kuželky, kde na závitové části stopky je uložena objímka, v níž je vytvořeno kuželové vybrání se sklonem ve stejném směru jako sklon kužele stopky a které je opatřeno závitem. Závit kuželového vybrání má shodné stoupání se závitovou částí tělesa. Na části kužele ve směru od čela stopky j® vytvořena závitová část, shodná se závitovou částí tělesa. Úhel sklonu kuželového vybrání objímky je větší než úhel sklonu kužele tělesa.The hoses of the prior art are eliminated by the hose end according to the invention, which is characterized in that the sealing plug is the other end housed in the end body, for example in its head connected to the shank, provided with a threaded portion extending into the hose cone to the shank face, on the one hand through a through hole adjacent to the through-hole of the sealing plug, where a threaded portion of the shank is fitted with a sleeve in which a conical recess is formed with a slope in the same direction as the shank cone and threaded. The thread of the conical recess has the same pitch with the threaded part of the body. A threaded portion identical to the threaded portion of the body is formed on the cone portion in the direction away from the shank face. The taper angle of the tapered recess of the sleeve is greater than the taper angle of the body cone.
Výhoda tohoto nového konstrukčního provedení koncovky spočívá v možnosti nasazení na kterýkoliv volný konec hadice a kdykoliv ji sejmout a znovu použít. To znamená, že v případě poškození hadice v místech koncovky se její patřičný kus odřízne, načež se koncovky předělá na nový konec hadice. Je-li hadice jinak poškozená, demontují se obě její koncovky a umístí se na novou hadici. Uvedené výhody se projeví zejména v těch případech, kdy nejsou hadice potřebných délek na skladě. Pro svoji jednoduchou a pohotovou montáž je použití zvláště výhodné v havarijních případech.The advantage of this new design is that it can be attached to any free end of the hose and removed and reused at any time. This means that in case of damage to the hose at the end of the fitting, the corresponding piece is cut off, then the fitting is redesigned to the new end of the hose. If the hose is otherwise damaged, both ends are removed and placed on the new hose. These advantages will be particularly noticeable in cases where hoses of the required length are not in stock. Because of its simple and quick assembly, use is particularly advantageous in emergency situations.
