Abstract

PURPOSE: To facilitate the replacement of the seal ring of a spherical valve, by splitting the ring into a plurality of segments.
CONSTITUTION: The seal ring 10 of a spherical valve comprises a pair of segments 10a of the same form and another pair of segments 10b of the same form. These pairs of segments are coupled with each other by fixation plates 11. The adjacent segments 10a, 10b are secured on each other by bolts inserted into the fixation plate 11. A rubber packing 13 is interposed between the adjacent faces of the ring segments 10a, 10b to make them watertight to each other. To fit the seal ring 10 in a valve casing, packings 7 are attached to two ring segments 10b and these packings and segments are set in the valve casing. The rubber packing 13 is then tentatively bonded on the adjacent faces of the ring segments 10b by a bonding agent. The other ring segments 10a are interposed between the former rings 10b. Finally, all these ring segments are secured on one another by the fixation plates 11 or the like.
