REUSABLE TOOL ASSEMBLY FOR PURGING FLUID FROM A FLUID FLOW PIPE SYSTEM OR A PORTION THEREOF

摘要

A reusable tool assembly for purging fluid from a fluid flow pipe system or a portion thereof is presented. The tool assembly includes an input portion configured to accommodate a positively-pressurized flow of air/gas, a flow control portion configured to regulate an amount of pressurized air/gas flow, and a pressure measurement gauge device configured to measure and indicate the amount of pressurized air/gas flow, as regulated by the flow control portion. The tool further includes and an output portion configured to introduce the regulated amount of pressurized air/gas flow into the fluid flow pipe system, the output portion containing a pressure-fitted slip coupling device that temporarily, releasably, and sealably engages an exterior, unthreaded surface of an open pipe portion providing access into the fluid flow pipe system and enabling the air/gas flow to purge fluid from the fluid flow pipe system.

1. A reusable, unitary tool for purging fluid from a fluid flow pipe system or portions thereof, the reusable, unitary tool having an interior channel of substantially uniform diameter and comprising:
an input portion configured with a male connector nozzle for unthreadedly insertively couple to a complementary female connecting end of a source of positively-pressurized flow of air/gas; a flow control portion configured to regulate an amount of the positively-pressurized air/gas flow communicated through the substantially uniform diameter interior channel; a pressure measurement device configured to indicate the amount of pressurized air/gas flow communicated through the substantially uniform diameter interior channel in accordance with the flow control portion; and an output portion for introducing the regulated amount of pressurized air/gas flow communicated through the substantially uniform diameter interior channel into the fluid flow pipe system or portions thereof, the output portion including a pressure-fitted slip coupling portion with an internal unthreaded arrangement that is configured to temporarily, releasably, and sealably slidably engage an exterior, unthreaded surface of a substantially cylindrical open pipe end portion of the fluid flow pipe system to enable the regulated pressurized air/gas flow to purge fluid from the fluid flow pipe system or portions thereof.
