Abstract
An auto flow steam trap has a hollow main casing having an inlet channel and an outlet channel, a float assembly mounted in the main casing, and a non-return valve assembly. With the non-return valve assembly mounted in the outlet channel of the main casing, the auto flow steam trap only needs one non-return valve assembly to control allowing the condensate to flow out of the main casing or not. Thus, the auto flow steam trap has advantages such as simple structure and low failure rate, easy assembling, and so on.
Claims16
An auto flow steam trap comprising:
- a main casing being hollow and having
- a peripheral wall;
- a top portion;
- a bottom portion;
- a partition panel securely mounted transversely in the main casing and dividing an interior of the main casing into an upper chamber and a lower chamber;
- an inlet channel formed through the main casing and having
- an exterior inlet communicating with an exterior of the main casing;
- and
- an interior inlet communicating with the upper chamber of the main casing;
- and
- an outlet channel formed through the main casing and having
- an exterior outlet communicating with the exterior of the main casing;
- and
- an interior outlet communicating with the lower chamber of the main casing;
- a float assembly mounted in the upper chamber of the main casing and having
- a tubular strainer securely mounted on the partition panel and having
- a peripheral wall;
- an upper closed end;
- a lower open end corresponding in position to the partition panel;
- and
- multiple through holes separately formed through the peripheral wall of the tubular strainer;
- a float slidably mounted in the tubular strainer;
- and
- an adjusting tube mounted on and protruding down from a bottom of the float, slidably mounted through the partition panel, protruding into the lower chamber of the main casing, and having
- a lower open end;
- a peripheral wall;
- and
- at least one guiding hole formed through the peripheral wall of the adjusting tube, and each of the at least one guiding hole extending longitudinally and tapering off toward an upper end of the at least one guiding hole;
- and
- a non-return valve assembly mounted in the interior outlet of the outlet channel and alternatively sealing or opening the interior outlet;
- wherein the non-return valve assembly seals the interior outlet in a normal status;
- and
- when a pressure in the lower chamber of the main casing is higher than a pressure of the exterior of the main casing, the non-return valve assembly is activated to open the interior outlet.
