Description
Изобретение относитс к заделке гибких трубопроводов в металлические наконечники . Шланги, заделанные в наконечники широко примен ютс во многих отрасл х промышленности , и, в частности, в самолетостроении , когда жидкости или газы подаютс к отклон ющимс силовым цилиндрам механизмов.This invention relates to the sealing of flexible pipelines into metal tips. Hoses embedded in tips are widely used in many industries and, in particular, in aircraft construction, when liquids or gases are fed to deflecting power cylinders of mechanisms.
Известно неразъемное соединение шлангов высокого давлени с муфтой, втулкой и соединительным элементом с кольцевым ножом .The one-piece connection of high-pressure hoses to the sleeve, sleeve and connecting member with a ring knife is known.
Однако в этом соединении возможно нарушение герметичности нри высоких давлени х из-за недостаточно плотного контакта между резиновым слоем и поверхностью.However, in this compound, a leakage at high pressures is possible due to insufficient contact between the rubber layer and the surface.
Известно также неразъемное соединение армированных рукавов высокого давлени , содержащее муфту, втулку с кольцевыми выступами и штуцер с ножевым элементом, образуюш.им с втулкой полость под уплотн ющую среду It is also known that the one-piece connection of reinforced high-pressure hoses, comprising a sleeve, a sleeve with annular projections and a nozzle with a knife element, forms a cavity with the sleeve under the sealing medium.
Известное соединение вл етс недостаточно герметичным при работе на высоких дав тени х.The known compound is not tightly sealed when operating at high pressures of shadow x.
Цель изобретени - повышение работоспособности при высоких давлени х.The purpose of the invention is to increase the performance at high pressures.
Это достигаетс тем, что ножевой элемент выполнен с конусными расточками, а внутренн поверхность муфты снабжена кольцевыми выступами.This is achieved by the fact that the knife element is made with tapered bores, and the inner surface of the coupling is provided with annular projections.
На фиг. изображено неразъемное соединение в продольном разрезе; на фиг. 2 - разрез А-А фиг. I.FIG. shows a permanent connection in longitudinal section; in fig. 2 - section A-A of FIG. I.
Неразъемное соединение состоит из штуцера I с ножевым элементом 2, муфты 3, рукава 4 с армировкой5, втулки 6 с рельефной поверхностью, кольцевой полости 7, конусной расточки 8, выступов 9, режущей кромки 10, кольцевой выточки 11, кольцевого буртика 12, цилиндрической расточки 13 и конфузорной проточки 14. С торца штуцера 1 выполнен ножевой элемент 2, на его конце выполнена режуща кромка 10, отThe permanent connection consists of fitting I with a knife element 2, coupling 3, sleeve 4 with reinforcement 5, sleeve 6 with a relief surface, an annular cavity 7, a conical bore 8, protrusions 9, a cutting edge 10, an annular recess 11, an annular shoulder 12, a cylindrical bore 13 and confused grooves 14. A cutter element 2 is made at the end of fitting 1, the cutting edge 10 is made at its end, from
которой выполнена конусна расточка 8, переход ща в цилиндрическую полость. Резиновый кольцевой слой посредством конусной расточки 8 обжат и располагаетс в полости ножевого элемента, плотно прилегает ко всей охватывающей его поверхности . Изнутри штуцера 1 выполнена выточка II, в которую развальцован кольцевой буртик 12 втулки 6, жестко соедин ющий втулку 6 с штуцером I, при этом образована кольцева полость 7 под уплотнительную среду. Цилиндрическа расточка 13 и конфузорна проточка 14 охватывают ножевой элемент через стенку рукава, чем обеспечивают надежную опору ножевому элементу 2. Выступы 9 сквозь наружную оболочку своими притупленными дугообразными вершинами изгибают металлическую армировку 5 на рельефной поверхности втулки 6, обеспечив надежную металлизацию армировки с соединением и прочно закрепив рукав 4 в соединении.which is made cone bore 8, passing into a cylindrical cavity. The rubber annular layer is compressed by means of a tapered bore 8 and is located in the cavity of the knife element and fits snugly to the entire surface surrounding it. Inside the fitting 1 there is a recess II, into which the annular flange 12 of the sleeve 6 is expanded, rigidly connecting the sleeve 6 with the fitting I, and an annular cavity 7 is formed under the sealing medium. The cylindrical boring 13 and the confused groove 14 enclose the knife element through the sleeve wall, which ensures reliable support for the knife element 2. The protrusions 9 through the outer shell with their blunt arcuate tops bend the metal reinforcement 5 on the relief surface of the sleeve 6, ensuring reliable metallization of the reinforcement with the connection and firmly securing sleeve 4 in connection.
Работает самоуплотн ющеес неразъе.мное соединение шлангов высокого давлени следующим образом.A self-sealing, integral, high pressure hose connection works as follows.
При заделке шланга в соединение и подключении его в действующую систему (пневматическую или гидравлическую) рабоча среда заполн ет кольцевую полость соединени и равномерно передает давление на все детали соединени .When sealing the hose into the joint and connecting it to the operating system (pneumatic or hydraulic), the working medium fills the annular cavity of the joint and uniformly transfers pressure to all parts of the joint.
Герметичность в соединении будет обеспечиватьс в кольцевой полости путем действи эффекта самоуплотнени за счет рабочей среды. При этом резиновый слой, расположенный в кольцевой полости 7, прижимаетс рабочи.м продуктом к ножевому элементу 2 как манжета и не пропускает рабочий продукт за него. Давление среды, восприни .маемое ножевым элементом 2, уравновешиваетс муфтой 3, цилиндрическа The tightness in the joint will be maintained in the annular cavity by the effect of self-sealing due to the working medium. At the same time, the rubber layer, located in the annular cavity 7, is pressed against the working product with the knife element 2 as a cuff and does not allow the working product to pass over it. The pressure of the medium perceived by knife element 2 is balanced by clutch 3, cylindrical
расточка 13 которой охватывает ножевой элемент 2 снаружи. Возникшее осевое усилие в рукаве 4 от действи давлени среды воспринимаетс армировкой 5 и надежно уравновешиваетс в соединении волнообразным ее защемлением между рельефами поверхности втулки 6 и выступами 9 муфты 3. При этом выс упы 9 муфты, име непосредственный кок,акт с металлической армировкой 5, надежно обеспечивают стенание с них статического электричества, предохран от искрообразовани .bore 13 which covers the knife element 2 from the outside. The resulting axial force in the sleeve 4 due to the pressure of the medium is perceived by the reinforcement 5 and is reliably balanced in the connection by its undulating pinching between the reliefs of the surface of the sleeve 6 and the protrusions 9 of the coupling 3. In this case, the heights of the coupling 9, having an immediate kick, act with metal reinforcement 5, reliably provide static moaning from them, protecting against sparking.
