Изобретение относитс к трубопрюводной арматуре и может быТь использовано в различных област х техники.The invention relates to pipe and pipe fittings and may be used in various fields of technology.
Известен тройник с концевыми цилиндрическими оболочками и центральной сферической оболочкой с горловиной 1 1Known tee with end cylindrical shells and a central spherical shell with a neck 1 1
Наиболее близким техническим решением вл етс тройник с концевыми цилиндрическими оболочками и центральной выпуклой оболочкой с горловиной . Центральна оболочка образована вращением сегмента вокруг хорды , а ось ее смещена относительно оси цилиндрических оболочек на величину , равную разности высоты сегмента и радиуса цилиндрических оболочек t 2 ЬThe closest technical solution is a tee with end cylindrical shells and a central convex hull with a neck. The central shell is formed by rotating the segment around the chord, and its axis is offset relative to the axis of the cylindrical shells by an amount equal to the difference between the height of the segment and the radius of the cylindrical shells t 2 b
Недостаток известных тройников заключаетс в том, что в зоне сопр жени центральной оболочки с горловиной возникает концентраци напр жении , снижающа прочность конструкции .A disadvantage of the known tees is that a concentration of stress occurs in the interface of the central shell with the neck, which reduces the strength of the structure.
Поставленна цель достигаетс тем, что центральна оболочка выполнена в В1иде огибающей семейства сфер, лини центров которых расположена на экспоненциальной кривой, смещенной относительно оси цилиндрических оболочек к горловине.This goal is achieved by the fact that the central shell is made in B1 of the envelope of a family of spheres, the lines of whose centers are located on an exponential curve that is displaced relative to the axis of the cylindrical shells to the throat.
Предлагаемое выполнение тройни10 ка обеспечивает плавное изменение кривизны центральной оболочки в зоне сопр жени с горловиной.The proposed implementation of a triple-ka ensures a smooth change in the curvature of the central shell in the interface with the throat.
На фиг. 1 изображен тройник, об15 щий вид, разрез; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез . Б-Б на фиг. 1.FIG. 1 shows a tee, general view, section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - cut. BB in FIG. one.
Тройник образован огибающей семейства сфер 1 центральной оболочки 2 The tee is formed by the envelope of the family of spheres 1 of the central shell 2
