Abstract

Et apparat for å drenere væske fra en tank omfatter et utløpsrør (20) med en første ende som kan plasseres nær bunnen (5) av en tank (3) og en annen ende som rager ut av tanken (3). Røret omfatter en tilbakeslagsventil (22) for å forhindre strøm av væske tilbake til tanken (3). En første stengeanordning (24) er plassert nedstrøms tilbakeslagsventilen (22) og kan anta en stilling som åpner eller lukker utløpsrøret (20). Et betjeningsrør (26) er i en første ende forbundet til utløpsrøret (20) og i en annen ende til trykkontrollanordninger (32, 34). Trykkontrollanordningene (32, 34) kan styres til å frembringe vekslende tilstander av undertrykk eller overtrykk i betjeningsrøret (26) på en slik måte at væsken i tanken (3) trekkes inn i betjeningsrøret (26) eller presses ut av tanken (3) gjennom utløpsrøret (20) inntil tanken (3) er drenert.An apparatus for draining liquid from a tank comprises an outlet pipe (20) having a first end which can be placed near the bottom (5) of a tank (3) and a second end projecting from the tank (3). The pipe comprises a check valve (22) to prevent flow of liquid back to the tank (3). A first closing device (24) is located downstream of the check valve (22) and may assume a position that opens or closes the outlet tube (20). A control tube (26) is connected at the first end to the outlet tube (20) and at a second end to pressure control devices (32, 34). The pressure control means (32, 34) can be controlled to produce alternating states of underpressure or overpressure in the control tube (26) in such a way that the liquid in the tank (3) is drawn into the control tube (26) or is pushed out of the tank (3) through the outlet tube. (20) until the tank (3) is drained.
