EVALUATION TESTS OF MOSLER BLAST VALVES.
Abstract
Determinations of closure times, pressure leakage, and structural stability of the valves were primary objectives of the tests. The first valve tested was a blast-actuated, tubular-type valve in which a movable set of steel dowels seals against a stationary set. For the range of pressures tested (3 to 18 psi), the valve closing time was between 4 and 9 msec. Some deformation was observed in the hollow, stainless-steel tubes (dowels) of the valve. The second valve tested was a blast-actuated, disk-type, 16-inch-diameter valve in which the disk seals against a steel seat assembly. This valve was not effective in sealing off the airblasts. The third valve tested was a remote-controlled, pressure -operated cylinder, 36-inch-diameter valve. In a series of 24 opening and closing cycles, the closing time averaged 73.1 msec and the opening time averaged 1.24 seconds; both times are well within the specified range. The valve showed no pressure leakage when subjected to pressures up to 80 psi and no structural damage was observed. Of the three designs tested, this valve gave the best results. (Author)
