MULTI-AGENT JOINT-USE CENTRAL ROTARY-BODY APPARATUS

摘要

A multi-agent joint-use central rotary-body apparatus. The apparatus comprises: a fixedly arranged turntable frame (5) and a turntable (1) rotatably arranged on the turntable frame (5), where the turntable (1) is actuated by an actuator apparatus (2) into rotation on the turntable frame (5). A rotatable part of a central rotary body (3) is fixedly connected with the turntable (1); a fixed part of the central rotary body (3) is fixedly connected with the turntable frame (5). The rotatable part of the central rotary body (3) comprises an outer output pipe (7), an inner output pipe (6) coaxially arranged within the cavity of the outer output pipe (7), and a rotary valve (10) fixedly connected at the exterior of the outer output pipe (7). The fixed part of the central rotary body (3) comprises an inner input pipe (16) sleeved onto the exterior of the inner output pipe (6), an outer input pipe (15) correspondingly sleeved onto the exterior of the outer output pipe (7), and sealing rings (14) arranged both between the pipe wall of the inner output pipe (6) and that of the inner input pipe (16) and between the pipe wall of the outer output pipe (7) and that of the outer input pipe (15). The apparatus not only is capable of delivering a fire-extinguishing agent, but also is capable of delivering simultaneously a combination of two or more fire-extinguishing agents.
