Abstract

An orifice-type condensate removal device where the orifice is contained within an independently removable gas trap insert. The gas trap insert can be removably connectable at an inlet end to a upstream body of the condensate removal device, which includes its other components, e.g. flow inlet connection, debris filter, etc. The gas trap insert may be removably connected at an outlet end directly to a pipeline, i.e. such that an end face of the gas trap insert forms a seal with the pipeline when the condensate removal device is mounted in the pipeline. The gas trap insert comprises a radially protruding insert flange having a downstream-facing surface configured to sealingly abut the downstream portion of pipeline.

Claims (16)

1. A condensate removal device for mounting in a pipeline, the condensate removal device comprising: an upstream body configured to be connectable to an upstream portion of pipeline to receive a flow of condensable gas; and a gas trap insert comprising a condensate drainage channel extending between an inlet side and an outlet side of the gas trap insert, wherein the condensate drainage channel includes a constricted passage that is occludable by condensate flow to restrict condensable gas flow through the condensate drainage channel, wherein the inlet side is removably connectable to the upstream body, wherein the outlet side is configured to be directly connectable to a downstream portion of pipeline, and wherein the outlet side comprises an insert flange having a downstream-facing surface configured to sealingly abut the downstream portion of pipeline.
2. A condensate removal device according to claim 1, wherein the downstream-facing surface of the insert flange includes a groove for receiving a gasket to form a seal with the downstream portion of pipeline.
3. A condensate removal device according to claim 1 or 2, further comprising an annular outlet flange disposed around an outer surface of the gas trap insert, wherein the annular outlet flange is configured to engage an upstream portion of the insert flange, and wherein the annular outlet flange is configured to be connectable to the downstream portion of pipeline to thereby apply a downstream-directed force on gas trap insert.
4. A condensate removal device according to claim 3, wherein the upstream portion of the insert flange comprises a first engagement feature, and a downstream facing portion of the annular outlet flange that is arranged to engage the upstream portion comprises a second engagement feature, the first and second engagement features having complementary shapes .
5. A condensate removal device according to claim 4, wherein the first engagement feature is a radially protruding ridge that joins the insert flange to an upstream portion of the gas trap insert, and the second engagement feature is a lip formed around a downstream edge of a bore through the annular outlet flange.
6. A condensate removal device according to any preceding claim, wherein the upstream body includes a debris filter .
7. A condensate removal device according to claim 6, wherein the upstream body further includes an inlet flange attached to the debris filter, the inlet flange being attachable to the pipeline to connect the upstream body to the upstream portion of pipeline.
8. A condensate removal device according to any preceding claim, wherein the inlet side of the gas trap insert is removably connected to the upstream body by a threaded connection .
9. A condensate removal device according to any preceding claim, wherein the inlet side is sealingly connectable to the upstream body.
10. A condensate removal device according to claim 9, wherein a seal between the gas trap insert and the upstream body is formed by a gasket that is compressible between the gas trap insert and the upstream body.
11. A condensate removal device according to claim 10, wherein one of the gas trap insert and the upstream body includes a protrusion having a threaded surface that forms part of a threaded connection between the inlet side of the gas trap insert and the upstream body, and wherein the gasket is mounted on the protrusion.
12. A condensate removal device according to claim 10 or 11, further comprising a spacer adjacent to the gasket between the gas trap insert and the upstream body.
13. A condensate removal device according to any preceding claim, wherein an outer surface of the gas trap insert includes a flattened region configured to provide an engagement portion for a gripping tool .
14. A condensate removal device according to any preceding claim, wherein the condensate drainage channel increases in cross-sectional area as it extends away from the constricted passage towards the outlet side of the gas trap insert .
15. A condensate removal device according to claim 14, wherein the condensate drainage channel tapers outwardly between the constricted passage and the downstream-facing surface of the insert flange.
16. A gas trap insert for use in a condensate removal device mounted in a pipeline, the gas trap insert comprising a condensate drainage channel extending between an inlet side and an outlet side of the gas trap insert, wherein the condensate drainage channel includes a constricted passage that is occludable by condensate flow to restrict condensable gas flow through the condensate drainage channel, wherein the inlet side is configured to be removably connectable to an upstream body of the condensate removal device, wherein the outlet side is configured to be directly connectable to a downstream portion of pipeline, and wherein the outlet side comprises a radially protruding insert flange having a downstream-facing surface configured to sealingly abut the downstream portion of pipeline.
