DRAINABLE SIGHT GLASS AND ASSOCIATED METHODS

摘要

Embodiments of the invention are directed to methods of use and a (trainable sight glass assembly for use with a sump pump having a pump housing and being adapted to view the condition of oil disposed, within the pump housing. In some embodiments, the drainable sight glass assembly can comprise a sight glass housing having an upper disk layer with a first diameter and a first threaded receptacle formed therein disposed on a top side of the sight glass housing, a lower disk portion with a second diameter and a second threaded receptacle formed therein and disposed on a bottom side of the sight glass housing, and a substantially transparent wall portion connecting upper disk layer to the lower disk portion so that the sight glass has a hollow, substantially frustoconically shaped interior when oil is not in the sight glass housing.

主权项

1. A drainable sight glass assembly to view the condition of fluid when disposed within a vessel, the drainable sight glass assembly comprising:
a sight glass housing including an upper disk layer having a first diameter and a first receptacle, a lower disk portion having a second diameter and a second receptacle, and a substantially transparent wall portion connecting the upper disk layer to the lower disk portion; an upper valve connected to the first receptacle, the upper valve for controlling fluid flow into the sight glass housing; and a lower valve connected to the second receptacle for controlling fluid flow out of the sight glass housing; the sight glass housing having a frustoconically shaped interior that tapers to a minimum diameter at a lower end substantially equal to the diameter of the lower valve.
