ABSTRACT:
A drop tube segment includes a conduit with a first end portion and a second end portion. The drop tube segment further comprises a valve assembly with a valve member associated with the first end portion, a float, and a linkage device pivotally connected with respect to the valve member. The linkage device is adapted for communication with the float such that the float may facilitate in adjusting the position of the valve member with respect to the first end portion of the conduit in response to a liquid level in a liquid reservoir. The drop tube segment further includes a fastening section located at the second end portion of the conduit for fluid tight fastening with an end portion of another drop tube segment. The fastening section comprises a sealing surface and a threaded portion adapted for threaded engagement with a threaded portion of another drop tube segment. The drop tube segment still further includes a sealing member that engages the sealing surface of the fastening section and is adapted to engage a sealing surface of another drop tube segment.
