Abstract

1530469 Degassing liquid; sampling device W DOCKHORN 24 Oct 1975 [26 Oct 1974] 43712/75 Headings B1D and B1M [Also in Division B8] An apparatus for separating gas from a gassy liquid comprises a cylinder I with a reciprocating piston 7 formed with one or more transfer passages 47, 48 which are closable by valves 19, 50, the apparatus being used to withdraw liquid, e.g. from a pressurized pipeline, through an inlet 34 by retraction of the piston. The inlet has a spring-biased 21 closed valve 6 which is opened during the initial part of the piston retraction by engagement between the piston and a spring 20. When the piston separates from the spring 20 the valve 6 closes and a liquid sample is trapped in the lower chamber of the cylinder. The further stroke of the piston causes the gas in the liquid to separate out and flow through the passageways 47, 48 in the piston during the downward stroke of the piston which returns the liquid to the pipeline. The valves 19, 50 of the piston are prevented from sticking by pins 22 slidable in passages 48. The gas or liquid removed from the liquid sample is removed from the upper chamber of the cylinder by argon gas. Filter disc 4 has by-pass apertures 36.
