US 9,086,180 B2 · Quick connect fire and dust suppression system

Abstract

A quick connect system for the assembly of underground mining dust and fire suppression systems can eliminate the need for threading pipe with couplings during the installation, reducing installation times approximately 75%. The quick connect system results in the quick and easy coupling and positioning of sprays along the water line. The quick connect system typically uses galvanized, brass and stainless steel components to reduce the need for replacement and to provide for quick adjustment of fittings with sprays using pliers. The system is simple to maintain and reduces high installation and maintenance labor costs. The system uses male and female ported fittings and horseshoe pins. Pendant style or deluge style sprays can be used in the system and can be pre-installed prior to delivery and installation of the system.
