Изобретение относитс к области машиностроени , а именно, к пластиковым трубам с раструбом.The invention relates to the field of mechanical engineering, namely, plastic pipes with a socket.
Извества пластикова труба с раструбом, во внутренней полостибAnts plastic pipe with a bell, in the internal cavity
которого установлвн уплотнйтельный элемент Ц.which is installed seal element C.
Известна также пластикова труба с раструбом, имею1дам два расшир ющихс участка, один нэ которых удер- Ю живает уплотнитель ый элемент 12.A plastic pipe with a bell is also known, having two expanding sections, one of which is supported by the sealing element 12.
Однако и известные трубы не обеспечивгиот надежного закреплени уплотнительного элемента.However, well-known pipes do not provide reliable fastening of the sealing element.
Цель изобретени - повышение на- Il6 дежности трубы s сборе.The purpose of the invention is to increase the reliability of pipe s on Il6.
Достигаетс она тем, что на трубе выполнен трети расшир ющийс участок с торцовым краем, изогнутым в направ .ггении второго расшир ющегос участка и образующим кольцевою канавку, в которой установлен уплотнйтельный элемент.It is achieved by the fact that on the pipe there is a third extending section with an end edge bent in the direction of the second expansion section and forming an annular groove in which the sealing element is installed.
На фиг. I представлена описываема труба с раструбом, конец которого25FIG. I presents the described pipe with a bell, the end of which 25

Т1ластикова труба 1 изогнута методом выдавливани из термопластичного материала, например из поливинилхлорида , и имеет три расшир ющихс участка 2-4: первый участок 2, внутренний диаметр которого больше диаметра трубы: второй участок 3, переходна наклонна стенка 5 которого переходит в участок 4. Верхний конец 6 пластиковой трубы 1 изгибают так, что он вновь располагаетс вдоль оси трубы. Свободный конец 7 верхнего конца третьего участка 4 при этом располагаетс напротив переходного участка 8 между третьим расшир ющимс участком и наклонной стенкой второго расшир ющегос участка . В пространстве, образованном третьим участком 4 и его изогнутым свободным концом, расположена, верхн часть 9 уплотнительного элемента 10.The plastic pipe 1 is bent by extrusion from a thermoplastic material, such as polyvinyl chloride, and has three expanding sections 2-4: the first section 2, the inner diameter of which is larger than the pipe diameter: the second section 3, the inclined transition wall 5 of which passes into section 4. The upper The end 6 of the plastic pipe 1 is bent so that it is again positioned along the axis of the pipe. The free end 7 of the upper end of the third portion 4 is located opposite the transition portion 8 between the third expanding portion and the inclined wall of the second expanding portion. In the space formed by the third section 4 and its curved free end, is located, the upper part 9 of the sealing element 10.
Рассто ние между свободным концом третьего участка и противоположным участком 11 раструба подбирают так, чтобы верхн часть элемента 10 была надежно зажата в канавке.The distance between the free end of the third section and the opposite section 11 of the socket is selected so that the upper part of the element 10 is securely clamped in the groove.
Изготавливают пластиковую трубку с раструбом следующим образом.Make a plastic tube with a bell as follows.
Пластиковую трубу 1 надевают на оправку, имеющую первый участок 12, переход щий во второй участок, диаметр которого больше диаметра первого участка, и третий участок оправки , в который переходит второй участок .The plastic pipe 1 is put on a mandrel having a first portion 12, passing into a second portion, the diameter of which is larger than the diameter of the first portion, and a third portion of the mandrel, into which the second portion passes.
Так образуют первый 2 и второй 3 расшир ющиес участки пластиковой трубы. Концевой, более широкий, участок оправки образует третий расшир ющийс участок 4 трубы.So form the first 2 and second 3 expanding sections of plastic pipe. The end, wider part of the mandrel forms the third expanding section 4 of the pipe.
Верхний конец 6 пластиковой трубы нагреваетс до температуры, при которой пластик деформируетс (например до температуры 140°с дл поливинилхлорида ) и внешн поверхность трубы 1 первым 2 и вторым 3 участками обкатываетс внешней формующей накладкой 13, котора поддерживаетс стенкой 14 и фиксируетс формующей накладкой 15.The upper end 6 of the plastic pipe is heated to the temperature at which the plastic deforms (for example, to a temperature of 140 ° C for polyvinyl chloride) and the outer surface of the pipe 1 by the first 2 and second 3 sections is rolled by the outer forming lining 13, which is supported by the wall 14 and fixed by the forming lining 15.
При помощи второй накладки 15, содержащей ваемку 16, верхний конец 6 изгибаетс в радиальном направлении после того, как установлена на свое место верхн часть 9 уплотнительного элемента, котора св зана с уплотн юишм звеном.With the help of a second lining 15 containing a wadding 16, the upper end 6 is bent in the radial direction after the upper part 9 of the sealing element, which is connected to the sealing lip, is installed in its place.
При помощи третьей внешней формующей накладки 17, котора также снабжена выемкой 18, верхний конец 6 деформируетс так, что ее конец направлен вдоль оси трубы 1.With the help of the third outer forming lining 17, which is also provided with a recess 18, the upper end 6 is deformed so that its end is directed along the axis of the pipe 1.
Внутренний диаметр трубы в точке, где расположена верхн часть 6 трубы и внутренний диаметр второго расширени заполн ют одинаковыми.The inner diameter of the pipe at the point where the upper part 6 of the pipe is located and the inner diameter of the second expansion are filled with the same.
