ACC-1 dry-type valve fast opening valve device industry, external reset ACC-1 dry-type valve quick opening device (hereinafter referred to as accelerator) is the DPV-1 Dry Type Valve (2-1 / 2 "3" 4 " 6 ") of supporting devices. ACC-1 Accelerator dry-type valve can be shortened from the nozzle (or only one) action to dry valve operation time. Wet or dry start to start the system by the nozzle boot system to provide a fire alarm signal flow alarm pressure switch action after pre-action system, so no need to design electrical fire detection system. Under normal circumstances cast steel valves, detection elements of the system designer to select a single chain of pre-action fire system response speed faster than the automatic fire sprinklers. Inflation pressure pipe network only 0.69bar, so the system piping system filled with water to wet gas valve, only experience a short delay before the fire sprinkler operation, the system is filled with water to a wet system.
