Product Description

 Diaphragm  type deluge alarm valve

                  ZSFM model deluge alarm valve adopt the principle of diaphragm and non-return, when the pipeline pressure which around diaphragm reach to balance, diaphragm will be in a closed position, when water supply system pressure exceed pipeline pressure, diaphragm will auto open a one-way check valve, and it can composed with other accessaries and become kinds of deluge alarm fire extinguisher systems.

 

 

Working Principle

               When the diaphragm is closed, the valve body is divided into upper and lower part. The upper part is connected with pipe network of automatic sprinkler system and the lower part is connected with pipe network of water supply system. The sealed cover and diaphragm form a cavity with pressure control. There is pipe connecting water supply pipe of upper valve body. When the cavity pressure and water supply line pressure keep balance, the diaphragm is in a sealing state(for the preparation condition). At this point, the water supply system is unable to supply water to the pipe network. When the cavity pressure drops, the diaphragm will automatically opens and supply water.
