摘要： An automatic drain valve for discharging accumulations of condensables and foreign materials from a pneumatic system. The drain valve (10) comprises a reservoir (14) defining an inlet (30) and an outlet (86) for flowthrough communications with a pneumatic system. A pilot valve (41) is mounted in the reservoir (14) for selectively communicating pressurized air to a valve operator (57), such that the valve operator selectively opens and closes a drainage valve (82) communicating with the outlet (88) of the reservoir (14) for selective draining the reservoir. The pilot valve (41) includes a sensor tube (42) which defines a valve seat (44) and includes a magnetized valve plug (46) for selectively engaging the valve seat (44), the valve plug (46) having a selected magnetic polarity. A level sensing float (52) disposed within the reservoir (15) carries an annular magnet (56) normally having a polarity opposite that of the valve plug (46) such that the annular magnet (56) acts upon the valve plug (46) selectively opening and closing the pilot valve (81) as the float (52) rises and falls from a raised position to a lower position with the level of liquid within the reservoir (14).

摘要： An automatic drain valve system for collecting and draining a liquid and/or contaminants within a reservoir (148) including a level sensing float (68'). The liquid or contaminants are introduced into the reservoir through an inlet (48) and exit the reservoir (148) through an outlet (176). A control valve which is responsive to the liquid level contained within the reservoir (148) includes coupled magnetic members which selectively open and close the control valve in response to the liquid within the reservoir (148) reaching preselected levels. This control valve activates the drain valve (34') for opening and closing the drain outlet such that the system is automatically drained upon when the liquid within the reservoir reaches a preselected level.

摘要： An automatic drain valve system for collecting and draining a liquid and/or contaminants within a reservoir (45A) including a level sensing float (68A). The liquid or contaminants are introduced into the reservoir through an inlet (48A) and exit the reservoir (45A) through an outlet (206). A control valve which is responsive to the liquid level contained within the reservoir (45A) includes coupled magnetic members which selectively open and close the control valve in response to the liquid within the reservoir (45A) reaching preselected levels. This control valve activates the drain valve (34A) for opening and closing the drain outlet such that the system is automatically drained upon when the liquid within the reservoir reaches a preselected level.
