Anti-drip device for water mist nozzle
Water mist nozzle pressure opening device (nozzle anti-drip device)
Install the constant pressure opening device between the water mist nozzle and the water mist pipeline, in the early stage of fire extinguishing, the pump set has just started, when the high-pressure water in the pipe network has not been fully established, the pressure in the water mist pipeline is lower than the minimum working pressure of the water mist nozzle, the device will not open, the water mist nozzle will not be sprayed out with a fine water flow, and will not cause water flow loss; When the fire extinguishing is completed, after the pump group stops, the residual water pressure in the pipe network is lower than the minimum working pressure of the water mist nozzle, the device will not be opened, and the fine water mist nozzle will not flow out or form water droplets with a fine water flow, which will not cause unnecessary water stain loss to the protection site.
