    Dry Alarm Valve

  Dry alarm valve is an important component of dry automatic sprinkler system, which is mainly composed of dry valve, hydraulic alarm, pressure switch and air pressure maintenance device.Dry automatic sprinkler system is a closed system developed on the basis of wet sprinkler system to meet the need of installing automatic sprinkler system in cold and high temperature places.

  Dry system adopts closed sprinkler head, which is usually filled with pressure gas (compressed air or nitrogen) in the side pipe network of the system.When there is a fire in the protection zone, the temperature will rise and the sprinkler head will feel the temperature, then the pressure gas will be released, which will lead to the decrease of the pressure on the side of the system pipe network. The pressure water on the side of the water supply will open a dry alarm valve and the system will sprinkler the fire.At the same time, a small amount of water flows through the alarm port to the hydraulic alarm and pressure switch to give alarm sound and alarm electrical signals.

  Dry system, inadequate water bar should be in a state of the pipeline, and filled with gas pressure, suitable for frozen dangerous due to environment temperature is too high and the water in the pipe may vaporize place fire protection, often used in ambient temperature below 4 ℃ or higher than 70 ℃.

    Wet Alarm Valve

  Wet alarm valve system is a kind of fixed fire extinguishing system commonly used in automatic sprinkler system. It is composed of wet alarm valve (including valve set, hydraulic alarm, delay device, pressure switch, etc.), water flow indicator, fire signal valve and closed sprinkler.

  The system is in standby state for a long time, full of pressure water in the pipe network, when somewhere there is a fire protection area, the environment temperature, make the temperature sensitive element on the nozzle (ball) action, falls off seal assembly, automatic startup system, the water spray directly to the fire area, and provide an alarm signal alarm, fire control, in order to achieve purpose.

  It is suitable for buildings which can extinguish fire with water, usually installed in production places, warehouses, hotels, shopping malls, hospitals, theatres, office buildings, high-rise buildings and garages, etc.

  Deluge Alarm Valve(ZSFM)

ZSFM series diaphragm deluge valves control the opening of the main valve in three ways.After the main valve is opened, the pressure enters the pressure switch and the hydraulic alarm sound: the pressure switch sends a signal to the control center or opens the fire pump.Diaphragm deluge valve has anti-reset structure, when the main valve through automatic or manual switch on the main valve, it needs to be manually operated before the main valve reposition closed.

    Preaction Device(ZSFY)

  ZSFY preaction device mainly consists of preaction alarm valve set, preaction device control panel, air pressure maintenance device and air supply device.ZSFY type pre-action device is a combination of fire detection and alarm technology and automatic sprinkler system, which plays a dual role in protecting objects.

  When there is no fire, the side pipe of the system is filled with air, so the system has the characteristics of dry system, which can meet the need of automatic sprinkler fire extinguishing under high temperature and cold conditions.
