Известны соединени  трубопроводов, со-т держащие цилиндрический ниппель со сферической головкой и накиднуто гайку.; Предлагаемое соединение отличаетс  тем hiTO упругость сферической головки определена соотношением толщины и наружных ; диаметров цилиндрической и сферической частей ниппел , |-a-s B-t-d-t-s в пределах 0,07-0,13 при гарантированном зазоре между внутренним диаметром гайки к головкой.. Это повышает надежность иупрощает монтаж соединени . На чертеже изображена конструкци  предлагаемого соединени  трубопроводов. Соединение содержит цилиндрический ниппель со сферической головкой 1, накидную гайку 2, прижимающую сферическую голов-: ку к стыкуемому элементу 3 через плавающее кольцо 4. Формула изобретени  Соединение трубопроводов, например, дл  подвода топлива в газотурбинном двигателе, содержащее цилиндрический ниппель со сферической головкой и накидную гайку, о т л и ч а ю щ е е с   тем, что, с целью повышени  надежности и упрощени  монта жа, упругость сферической голопки определена соотношением толщины и наружных диаметров цилиндрической и с4 ер ческ;ой частей . D-d-s ; jB пределах о,07-0,13 при гарантироваи:ном зазоре между внутренним диаметром гайки и головкой.Pipeline connections are known that contain a cylindrical nipple with a spherical head and a nut is fastened .; The proposed compound differs in that the hiTO elasticity of the spherical head is determined by the ratio of the thickness and the outer; diameters of the cylindrical and spherical parts of the nipple, | -a-s B-t-d-t-s within 0.07-0.13 with a guaranteed gap between the internal diameter of the nut to the head. This increases the reliability and simplifies the installation of the connection. The drawing shows the design of the proposed piping connection. The connection contains a cylindrical nipple with a spherical head 1, a cap nut 2, which presses the spherical head to the abutting element 3 via a floating ring 4. The invention Connection of pipelines, for example, for supplying fuel in a gas turbine engine, containing a cylindrical nipple with a spherical head and a cap nut, so that, in order to increase reliability and simplify installation, the elasticity of the spherical golopka is determined by the ratio of the thickness and outer diameters of the cylindrical and c4 ep EQF; the second part. D-d-s; jB limits o, 07–0.13 with a guarantee: the nominal gap between the internal diameter of the nut and the head.
