HIGH CAPACITY BLAST VALVE DEVELOPMENT.
Abstract
A series of experimental valves varying in capacity from 700 cfm to 10,000 cfm with 1.0 inch of water flow resistance were developed and tested. A 2500 cfm valve evolved after a series of tests. Experimental work with the 2500 CFM valve module indicated that a pressure balance across the piston caused the shock catcher to be ineffectual, particularly at low overpressures. Remedial measures included decreasing piston clearance, installing an 0-ring seal, and venting the downstream end of the shock catcher barrel. Following a series of tests, a 10,000 cfm high capacity valve, which consisted of four 2500 cfm valves in a parallel arrangement within the same housing, was designed and fabricated. The valve was field tested at operation PRAIRIE FLAT. (Author)
