SELF-CLEANING ELECTROMAGNETIC VALVE OF A CONDENSATE DRAIN

摘要

The subject of the present invention is a self-cleaning electromagnetic valve arranged on a device for an automatic condensate drain from a compressed air system or another tube system or gas storage system, where condensate is produced. The valve is an electromagnetic valve and operates by a longitudinal stroke of the plunger, i.e. it opens and closes the flow by a stroke up and down and is characterised in that the condensate enters above the plunger (34), i.e. the condensate enters at one side of the plunger (34) and exits at another side of the plunger (34), and the plunger (34) is provided with means for the flow of condensate at its upper front and optionally along the lateral surface area. The plunger may have a shape of a cylinder or a truncated cone and may be provided with at least one means for condensate drain on the top, said means being in the shape of a radial or curved groove, and with at least one means for condensate drain on the lateral surface area in the form of a longitudinal groove or a groove in the form of a helix.
