Abstract
A condensate removal device for capturing, measuring and removing condensate from a fluid system having air or gas under pressure. The device purges only condensate on demand without loss of relative pressure inherent within the system. A differential pressure sensor senses the low and high level of condensate in a condensate collection reservoir activating a diaphragm type discharge valve venting condensate from the reservoir. Once condensate levels fall below a pre-determined level within the reservoir the valve is closed awaiting accumulation of additional condensate before cycling again.
Claims4
A condensate trap and drain apparatus for systems under pressure, wherein said apparatus comprises:
- a. a condensate collection reservoir, the collection reservoir being formed within a housing, the housing being connected to an inlet port;
- b. a purge outlet port extending from said reservoir, a passageway connects the reservoir with the purge outlet port, the purge outlet port having a diaphragm normally closing the passageway, the diaphragm being controlled by a purge valve;
- c. a first sensing probe projecting within said collection reservoir, the sensing probe detecting the pressure within said reservoir;
- d. a second sensing probe detecting the pressure within said reservoir, the first sensing probe being in vertical spaced relation with the second sensing probe;
- and
- e. a solenoid being connected to the purge valve, the solenoid responding to a solenoid drive.
