    • A serviceable multiport conversion system (40) for a conventional butterfly valve includes two fittings (31, 32). A first "T" fitting (32) contains two passageways (81, 82) which join at an internal common bore adjacent a separating wall (84), the wall defining a secondary seat (88) of the multiport valve. Circumscribing the common bore is an annular flange. A second fitting may be a similar "T" fitting or an "L" fitting. The "L" fitting contains a single passageway which terminates at an internal bore circumscribed by an annular flange. In use, the butterfly valve is removably positioned in sealing engagement between two fittings, with the flanges releasably attached and the inner diameters of the flanges co-extensive with the butterfly valve bore.
    • 用于传统蝶阀的可使用的多端口转换系统(40)包括两个配件(31,32)。 第一“T”配件(32)包含两个通道(81,82),该通道连接在与隔离壁(84)相邻的内部公共孔中,该壁限定多端口阀的次级座(88)。 环形通孔是环形法兰。 第二配件可以是类似的“T”配件或“L”配件。 “L”配件包含单个通道,其终止于由环形凸缘限定的内孔。 在使用中,蝶阀可拆卸地定位在两个配件之间的密封接合中,其中凸缘可释放地附接并且凸缘的内径与蝶形阀孔共同扩展。
