Abstract:
1. A removable pressure testing device for use in testing the pressure in a pipe line having an interior diameter and having a fitting with a flow path through the fitting along a longitudinal axis of the flow path, the fitting having a port and a recess encircling a portion of the flow path opposite the port and into which the testing device is inserted to block fluid flow through the fitting for testing, the pressure testing device sized to removably fit through the port during use, the pressure testing device comprising: a top configured to mate with the port, a continuous sidewall extending between opposing sides of the top and depending from the top a distance sufficient to block the flow path when the device is inserted into the fitting; two opposing faces joined to the sidewall and to the top to form an enclosed structure, each face joined to one of the surfaces on the top, one face being an upstream face and the other a downstream face, the faces and sidewall configured to form a fluid tight seal with the recess in the fitting during use; a first opening in the upstream face, the first opening being located to be placed within the fluid flow path through the fitting when the testing device blocks flow through the fitting; a second opening in the downstream face, the second opening being located to be placed within the fluid flow path through the fitting when the testing device blocks flow through the fitting; a first fluid passage placing the first and second openings in fluid communication; a dual valve assembly having first and second independent, manually actuatable valves in fluid communication through a second fluid passage in the pressure testing device, the first valve having a first closed position that blocks flow through the first fluid passage and having a second open position that allows flow through the first fluid passage, the second valve having a fluid outlet that is accessible externally of the testing device and having a first closed position blocking flow through the second valve outlet and further having a second open position allowing fluid flow through the first valve and the second valve outlet.
