ABSTRACT:
A vertically oriented float assisted automatic driptrap mechanism having a float valve chamber defined by a body section and base is disclosed. A float is located for vertical liquid level responsive movement within the float valve chamber and reciprocates within a valve stem float guide. A diffuser is provided at the inlet of the chamber to prevent impingement of incoming fluid on the float. The valve stem guide also serves as a filter support for a filter which filters out contaminants that might interfere with the valving action of the driptrap mechanism. A valve seat having a tapered seat surface and a self-positioning valve plug movably supported by the valve stem and having a differently tapered sealing surface establish line contact sealing to ensure effective valve operation under high pressure conditions.
