Water alarm Water alarm is an all-day hydraulic drive mechanical alarm, an alarm can be issued at the time of continuous operation of the sprinkler system. This alarm is easy to install, usually mounted on the facades oil valve, when the water flow through the wet alarm valve, dry pipe valves or deluge valve flow to the hydraulic alarm, bell that is ringing. Light water alarm impeller designed with the latest technology, can emit a high-frequency, high-intensity sound. Alarm, envelopes accessories and casing made of corrosion-resistant alloys by the drive shaft without lubrication. When installing the bell placed in an envelope tightly fitting into the valve specifications, therefore no special cover or special protection. This is suitable for all types of sprinkler systems. Action Description: When the sprinkler system operation, water from the wet alarm valve, dry pipe valves or deluge valve alarm through DN20 pipe into the pump casing, through its internal 3mm nozzle, resulting in high-speed jet turbine impact, so the turbine, Alert crank shaft and rotating parts. When the alarm accessories crank rotation, it hit a sustained alarm bell body. Water through the drain DN25 discharged from the pump. As long as the water continues to flow through the sprinkler system, the water alarm will always sound. Close alarm mounted on the wet alarm valve, dry pipe valve or deluge valve control valve can make a silencer. Water alarm after the operation can be automatically restarted. If the operation by closing the alarm control valve leaving the bell stopped ringing, you need to set it again when the sprinkler system, reset the alarm control valve. Alarm valve, dry pipe valves, hydraulic alarm deluge valve to the pipe diameter should be used ≥20mm total length should not exceed 23m (75ft) knowledge Daquan valve to reduce pressure losses. Water alarm valve should not exceed a height of more than 6.1m (20ft). DV-5 Diaphragm type deluge valve and deluge system DN40 ~ DN200 1.72 Mpa external reset, vertical or horizontal mounting DV-5 Deluge Valves are diaphragm type structure, valve size DN40-DN200, can be mounted vertically or horizontally . Automatic control valve used to supply water systems and other fire protection systems - in the deluge system, pre-action system, foam. Matching the appropriate valve piping components in the system operation, the deluge valve to provide a fire alarm signal. Deluge valve with external reset function, without opening the valve hand hole, simple pressure on the diaphragm valve chamber, you can reset the deluge systems or pre-action system. In addition to the membrane structure, the valve is not connected to the valve and rotating parts. The valve / external anti-corrosion coatings. When the valve is used for the deluge system, internal anti-corrosion coating can be resistant to seawater and salt corrosion. External anti-corrosion coating so that the valve can be used in a corrosive environment, industrial and outdoor installation.
