Beschreibung
Zusammenfassung:	quick-detachable articulated joints allowing considerable angular mobility of pipes relative to each other; erection of pipe lines in oil and gas industries. SUBSTANCE: Articulated joint has bell-mouth where slot is made; this slot is used for placing the seal; bell-mouth has additional slot for receiving the elastic gasket made from microporous rubber, for example, and steel shut-off member in form of split ring. Ball member has spherical surface of large radius equal to radius of inner surface of collar made in form of ring with outer curvilinear projection and concentric spherical surface of smaller radius which is engageable with seal made in form of self-sealing rubber ring having dovetail shape. EFFECT: enhanced strength and tightness of joint. 1 dwg
