CONDENSATE REMOVAL APPARATUS

摘要

A condensate removal device which includes two parallel paths for removal of condensate and gases from a fluid system is provided with a thermostatically operated valve in one path and a drain orifice of a preselected size in the other path. The combination is disclosed as it is used in drain lines of a steam system. A bellows or other thermostatically operated valve controls one path to the drain and is in the open position during warmup of the system to permit the passage of the large quantities of air, condensate, particulates and other matter which are present in the system during the warmup stage of operation. The thermostatic element is designed to be closed at operating temperatures. The drain orifice in the other path is designed to continuously pass the condensate and the like which will form in the line when the system is at or near operating temperatures while restricting the passage of working vapor.
