ACC-1 dry-type valve fast opening valve means wet rain, 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"), supporting devices. ACC-1 Accelerator dry-type valve can be shortened from the nozzle (or only one) action to dry valve operation time. ACC-1 dry-type valve Accelerator can automatically adjust the system in small, slow pressure changes. And when the system fast and stable pressure drop (eg sprinkler operation), the accelerator operation. Wet after rain Accelerator valve action picture, the intermediate chamber pressurized gas transmission system side to DPV-1 Dry-type valve, the valve will remain closed differential pressure damage and the dry valve is open. ACC-1 dry-type valve Accelerator has a unique, built-in direct action anti-overflow device and float through a combination of both, can block the water and impurities into the accelerator sensitive operating area. Sealing and locking anti-flooding devices depends directly on the ACC-1 Accelerator own motion, after the middle of the dry valve chamber without waiting to accumulate a certain pressure. Performance gear locking pin to make anti-overflow device at the drainage system can remain sealed. When the dry valve malfunction wet rain valve site, such as compressor failure and the pressure gradually decreased due to leaks in the system, the float will seal the control chamber entrance. ACC-1 dry-type valve Accelerator can replace the CentralB type, GemF311 type, StarS430 accelerators. Except when other valves DPV-1 Dry Type valve is fitted ACC-1 Accelerator, please contact the technical service department, to obtain relevant information. QRS type electronic dry quickly turn on the external device reset valve dry valve electronic accelerator uses a unique system air pressure monitoring device (UL and ULC announced, FM certification QRS type fire extinguishing system accessories), 2 times per second continuous sampling system air pressure. When the air pressure decline rate than 0.007bar / sec of continuous falls, confirmed by three consecutive samples, QRS signals wholesale wet rain to the fire control valve box, fire control box emit electromagnetic valve opening signal to open the solenoid valve QRS The system pipe network pressure by QRS dry pipe valve seat into the intermediate chamber, and the dry valve to accelerate open. Wet rain valve quality, Jianghan wet rain valve, a mechanical and electrical Anyuan Anyuan by the Hubei Chong Electrical Equipment Co., Ltd. to provide.
