FIELD: flared tube joints, possibly used in water supply systems of cities and industrial objects.
SUBSTANCE: tube joint includes inner tube with cylindrical surface and female flared tube. In cone gap between said tubes elastomer sealing member is placed. Said sealing member is compressed by means of flange and mounting parts. Sealing is realized by means of cone end flange, yokes joined along cone surface with flange and bolts whose stability is provided by means of annular step of cone lug at outer side of flared portion. Number of yokes (no less than two) is selected depending upon diameters of joined tubes. Size of internal cavity of yokes provides guaranteed gap h between yoke and cylindrical lug of flared portion at maximum diameter of lug. Axes of openings for bolts are normal relative to surfaces of yokes and respectively to joined surfaces of yoke and flange.
EFFECT: simplified design of members of tube joint, enlarged operational possibilities, improved sealing reliability of joint.
