Abstract

See full text

A manway assembly features a nozzle featuring a groove. A cover is attached to the nozzle and may be pivoted between open and closed positions. Retainers secure latch segments to the cover so that they may slide with respect to the cover. A latching mechanism moves the latch segments into and out of engagement with the groove of the nozzle sidewall when the cover is in the closed position. The latching mechanism may include a screw rod that is turned to move the latch segments. The nozzle may also include a nozzle rim that is provided with the manway assembly and secured to a remaining portion of the nozzle. The nozzle assembly may also include an outer cover attached to the nozzle in a hinged fashion and adapted to cover the manway cover when in the closed position to protect the latching mechanism from the environment and tampering.
