Abstract

Изобретение относится к строительной отрасли. Технический результат: расширение арсенала средств для соединения жесткого, преимущественно из металлического сплава, корпуса элемента трубопроводной арматуры с трубой из полимерного материала, в частности из полипропилена или из полиэтилена, которое отличает высокая надежность обеспечения герметичности, высокая нагрузочная способность, продолжительный срок службы и которое не приводит к значительному увеличению гидравлических потерь по причине зауживания проходного сечения. Узел соединения содержит выполненный на жестком корпусе 1 прямого фитинга патрубок 2, тонкостенную гильзу 3 с отбортовкой 4 наружу на одном из торцов, расположенную внутри подсоединяемого конца трубы 5 из полимерного материала с упором отбортовкой 4 в торец 6 конца трубы 5, накидную гайку 7, обжимную втулку 8 и уплотнительное кольцо 9. Патрубок 2 выполнен с участком 10 наружной резьбы и внутренним отверстием 11 с цилиндрической поверхностью, перпендикулярной оси внутренней ступенькой 12, а также с внутренней конической поверхностью 13, обращенной к свободному торцу 14 патрубка 2 и открытой со стороны свободного торца 14 патрубка 2. Накидная гайка 7 выполнена с внутренним радиальным кольцевым выступом 15 с конической поверхностью 16, обращенной внутрь полости накидной гайки 7 и расположенной вдоль внутреннего края кольцевого выступа 15. Гайка 7 навинчена на патрубок 2 по его участку 10 наружной резьбы. Конец трубы 5 вставлен во внутреннее отверстие 11 патрубка 2 с упором отбортовкой 4 через уплотнительное кольцо 9 во внутреннюю ступеньку 12. Обжимная втулка 8 изготовлена из металлического сплава со сплошной формой по направлению образующихThe invention relates to the construction industry. Technical result: expansion of the arsenal of means for joining a rigid, mainly metal alloy, body of a pipe fitting element with a pipe made of a polymeric material, in particular polypropylene or polyethylene, which is distinguished by high reliability of ensuring tightness, high load capacity, long service life and leads to a significant increase in hydraulic losses due to narrowing of the flow area. The connection node contains a pipe 2, made on a rigid case 1 of a direct fitting, a thin-walled sleeve 3 with flanging 4 at one end, located inside a connecting end of a pipe 5 of polymer material with an emphasis flanging 4 into the end 6 of the end of pipe 5, a cap nut 7, crimping the sleeve 8 and the sealing ring 9. The nozzle 2 is made with a section 10 of the external thread and the internal hole 11 with a cylindrical surface perpendicular to the axis of the internal step 12, and also with an internal conical surface 13 facing the free end 14 of the nozzle 2 and the open end of the free end 14 of the nozzle 2. The cap nut 7 is made with an inner radial annular protrusion 15 with a conical surface 16 facing the cavity of the cap nut 7 and located along the inner edge of the annular protrusion 15. The nut 7 is screwed onto the nozzle 2 in its section 10 external thread. The end of the pipe 5 is inserted into the inner hole 11 of the nozzle 2 with an emphasis flared 4 through the sealing ring 9 into the inner step 12. The compression sleeve 8 is made of a metal alloy with a solid form in the direction of
