Accumulated oil separator for oil-gas recovery system

An accumulated oil separator for an oil-gas recovery system, said oil separator is provided with a main body having an outer screw-connecting end and a rear inner screw hole;

• said main body is provided with a plurality of oil passageways on an inner wall of and extending from a front end to and communicating with a rear end of said main body;
• an oil-gas connecting pipe spaced away from said oil passageways is provided on said front end of said main body, and has an axial central hole with a predetermined diameter;
• and a through hole with a predetermined length is extended inwardly from said rear inner screw hole and is concentric with said axial central hole of said oil-gas connecting pipe;
• a radially extending chamber is extended downwardly a predetermined depth from a top surface of said main body and is communicated on its two lateral sides with said axial central hole of said oil-gas connecting pipe and said through hole with a predetermined length;
• a regulatory controlling means is mounted in said radially extending chamber to control normal oil filling and oil-gas recovery, or is regulated to be in an accumulated oil removing state, an accumulated oil discharging outlet is formed by drilling from outside to communicate transversely with said radially extending chamber;
• said regulatory controlling means has an exposed cap for force exerting for rotating and positioning, and is provided on its shank with a radially-extending hole extending through said shank and is adapted to being optionally communicated with said axial central hole of said oil-gas connecting pipe and said through hole with a predetermined length during rotating, and is provided on said shank with a connecting hole formed by drilling in another angular direction to communicate with said radially-extending hole (but not extend through said shank) and adapted to optionally communicating with said accumulated oil discharging outlet during rotating.
