STEAM TRAP WITH REINFORCED PRESSURE LEAKAGE PREVENTION CHECK VALVE

摘要

The present invention is to provide a steam trap. The present invention accurately discharges condensate using a check valve and accurately prevents a leakage of internal pressure of the steam trap; thereby increasing a reliability of a production facility, a steam pipe facility, a heat exchanger, and others operated by steam in all industrial fields. The steam trap comprises: a connection sleeve (10) connected to a steam pipe; an orifice sleeve (20) coupled to the connection sleeve (10) to be arranged on a condensate discharge passage between the steam pipe and the connection sleeve (10) having orifices (OR) therein; and a check valve (30) arranged in a chamber of the orifice sleeve (20) to prevent leakage of the internal pressure of the steam pipe through the orifices (OR) or the backflow of external pressure through the orifices (OR). The chamber of the orifice sleeve (20) is partitioned into two or more parts by barriers (SW). The orifices (OR) are arranged in the barriers (SW). The check valve (30) is embedded in one among two or more chambers.
