REMOVABLE ORIFICE PLATE DEVICE

摘要

The present disclosure relates to a removable orifice plate device which has an orifice plate having a circular portion with an aperture therein, and a graspable end portion extending therefrom. A tee body is included which has oppositely extending first and second tee runs and a tee branch. The tee runs are coupled to gas inflow and outflow pipes. The tee body has internal structure forming a slot which is aligned with an opening formed by the tee branch, and which receives the circular portion of the orifice plate. The orifice plate, when installed in the slot in the tee body, thus allows a flow of fluid only through the aperture. A removable cover encloses the orifice plate within the tee body.

主权项

1. A removable orifice plate device, comprising:
an orifice plate having a circular portion with a precisely dimensioned aperture therein, and an end portion graspable with the fingers of one hand which extends from the circular portion; a tee body having oppositely extending first and second tee runs, and a tee branch extending non-parallel to the first and second tee runs; the first tee run configured to be coupled to a gas inflow pipe; the second tee run configured to be coupled to a gas outflow pipe; the tee body having internal structure forming a slot, the slot being aligned with an opening formed by the tee branch and configured with a dimension for receiving the circular portion of the orifice plate such that the orifice plate, when installed in the slot in the tee body, allows a flow of fluid only through the aperture; and a cover adapted to be removably secured to the tee branch to enclose the orifice plate within the tee body.
