US 12,485,933 B2 · Segment isolating valve for pneumatic transport system

Abstract

Segment isolating valves assembled on the lower back of the elevated guideway (1), the plug base (2) being hinged on a housing (3) fixed to the elevated guideway (1) by a flange (4) for fast connection and disconnection. The housing (3) is equipped with a rainwater runoff tank (5). The segment isolating valve comprises a plug (2) mounted in a housing (3) affixed to the elevated guideway by means of a flange (4) for fast connection and disconnection. The plug (2) is moved by means of a linear actuator (6), whose rod exerts force on an articulation (7), which is pivoted above on the plug (2) and below on a frame (8) affixed to the housing base (3). The assembly is mechanically locked through a closed position locking cam (9), displaced automatically by springs (10). A safety locking pin (11) is actuated by a release solenoid (12).
