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 action Hankou wet rain valve, 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, such as compressor failure and when the air pressure in the system due to leaks slowly lowered, the float will seal the control chamber entrance. DV-5 electric / electrical double interlock pre-action system DN40 ~ DN200 electric / electrical double interlock pre-action system consists of a pre-action valve (DV-5 Deluge valve and check valve composition) and the appropriate piping, fire detection systems, air compressor, automatic pressure maintenance device, closed nozzle, pipe networks and water supply control valve. Electric / electrical double interlock pre-action system designed for applications requiring maximum water level to prevent systematic errors places, such as cold storage. It can also be used for water damage sensitive political and economic spaces, such as computer rooms, storage of valuables, heritage warehouses, libraries, archives, hotels, convention centers and other places. Electric / electrical double interlock pre-action system requires the installation of electrical fire detection system wet deluge valves, Preaction Valve with electric start start device is a solenoid valve pipe. The first electrical signal is an electrical detection systems or manual / electric emergency open valve means. The second electrical signal is a low-pressure warning system pipe network pressure switch Qiaokou wet rain valve, closed nozzle action, the system pipe network pressure drop, low alarm pressure switch. When two independent signals are sent to the fire control box, fire control box issue 24VDC solenoid valve opening signal, pre-action pressure relief valve diaphragm chamber, pre-action valve is opened. If there is only a signal, fire control box only send an alarm signal, pre-action valve will not open.
