Abstract

Технический результат изобретения заключается в реализации узла соединения металлического фитинга, имеющего внутреннюю коническую посадочную поверхность, с полипропиленовой трубой, который предусматривает одно механическое соединение и возможность соединения контактной сваркой с полипропиленовой трубой, используемой для системы отопления или водоснабжения здания или сооружения. Металлический фитинг 1 соединен с полипропиленовой трубой 2 с использованием штуцера 3 из полипропилена, на который установлена накидная гайка 4. На первом конце 7 штуцера 3 выполнена обращенная к этому концу коническая наружная посадочная поверхность 8 и далее расположен цилиндрический концевой участок 5. Буртик 9 выполнен у большего основания конической наружной посадочной поверхности 8. Штуцер 3 поджат конической наружной посадочной поверхностью 8 к внутренней конической посадочной поверхности 11 фитинга 1 накидной гайкой 4, сопряженной внутренним радиальным кольцевым выступом 12 с поверхностью буртика 9 со стороны второго конца 13 штуцера 3 и навинченной на наружную винтовую поверхность 14 фитинга 1. Цилиндрический концевой участок 5 штуцера 3, на который одет кольцевой уплотнительный элемент 6, располагается в цилиндрическом отверстии 15 фитинга 1 с радиальным зазором 16, причем кольцевой уплотнительный элемент 6 сжат между наружной поверхностью цилиндрического концевого участка 5 штуцера и внутренней поверхностью цилиндрического отверстия 15 фитинга 1, а также сопряжен со ступенькой 18 штуцера 3, расположенной с сопряжением с меньшим основанием конической наружной посадочной поверхности 8 и образованной кольцевой поперечной плоской опорнойThe technical result of the invention consists in the implementation of the connection node of a metal fitting having an internal conical seating surface with a polypropylene pipe, which provides for one mechanical connection and the ability to be welded to contact with a polypropylene pipe used for heating or water supply of a building or structure. The metal fitting 1 is connected to the polypropylene pipe 2 using a polypropylene nipple 3, on which a cap nut 4 is installed. At the first end 7 of the nipple 3, there is a conical outer surface 8 facing this end and then a cylindrical end section 5 is located. a larger base of a conical outer seating surface 8. The fitting 3 is clamped by a conical outer seating surface 8 to the inner conical seating surface 11 of the fitting 1 with a cap nut 4 mated in morning radial annular protrusion 12 with the surface of the flange 9 from the side of the second end 13 of the fitting 3 and screwed onto the outer screw surface 14 of the fitting 1. The cylindrical end section 5 of the fitting 3, which is surrounded by an annular sealing element 6, is located in the cylindrical hole 15 of the fitting 1 with radial the gap 16, and the annular sealing element 6 is compressed between the outer surface of the cylindrical end section 5 of the nozzle and the inner surface of the cylindrical hole 15 of the fitting 1, and also is associated with stu Enko 18 fitting 3 disposed to mate with the smaller base of the conical outer surface of the seat 8 and an annular transverse bearing plane
