DETACHABLE SEALING YOKE Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: detachable sealing yoke has flexible belt and mechanism for tightening the belt. The mechanism includes, e. g., tightening links coupled with the ends of the belt. Each of the links is pivotally connected with the housing and axle. The axles of the pivots are interconnected through a tightening screw. The sealing belt has the part with rectangular opening provided with sealing member. The closed loop made of the sealing belt immediately encloses the sealing flexible joint and is formed so that one end of the belt passes through the rectangular opening in the direction from internal space of the loop to the outside to define the zone of intersection of one part of the belt with the other. This zone can be positioned at any site on the loop over its periphery with respect to the mechanism for tightening the belt. In particular, the intersection zone can be coincident with one of the links of the mechanism for tightening the belt. In this case the opening and the sealing member are provided on the shank of the link. EFFECT: enhanced reliability. 4 cl, 5 dwg
