Title: Moisture extractors for gas lines
IPC: F16T1/38
Filed: 1961-03-13
Abstract: 907,607. Moisture or oil extractors for compressed-gas lines. WOODMANSEE, J. B. March 13, 1961 [Sept. 6, 1960], No. 9075/61. Class 64 (2). [Also in Group XXIX] A moisture or oil extractor for separating and automatically ejecting entrained liquid from compressed gas flowing through a pipe line has within it a cylinder in which slides a piston to which is connected a valve controlling a discharge opening from a sump within the casing of the extractor. The piston has one or more passages to allow gas to pass from a gas inlet to a gas outlet, and these passages can be closed by a float which rises as liquid is collected in the sump so that incoming gas pressure operates on the piston to move it and hence open the discharge valve. Gas enters at an inlet 11 and is deflected downwardly by an arcuate baffle 15, passes up through a piston 27 through passages formed by downwardly projecting tubes 32, and passes out of the extractor at an outlet 12. Any moisture removed from the gas drains into a sump 19 which has a discharge opening 22 closed by a valve 24 connected directly to the piston 27 by a rod 26. The position of a float 33, slidably mounted on the rod 26 is determined by the amount of liquid collected in the sump 19, and at a certain level a ring 35 of sealing material, loosely carried on the float 33 engages the tubes 32 thus closing the gas flow from the inlet 11 to the outlet 12. A pressure differential is then set up so that the piston moves upwardly opening the valve 24. The liquid in the sump 19 is quickly discharged under pressure, and the pressure differential is terminated as soon as the piston 27 moves across the outlet 12 to allow a free passage of gas from the inlet 11 to the outlet 12. At this point the float 33 drops away from the piston due to the influence of gravity and the piston 27 is pushed downwardly under the influence of a spring 29 until the valve 24 once more closes the discharge opening 22. The operation is then repeated.
