Working principle: The pressure water provided by the system drives the turbine to rotate and drives the proportional pump to send a certain amount of foam liquid into the device to mix with the pressure water and then supply it from the liquid outlet to the foam generating device for fire extinguishing. The amount of foam liquid is proportional to the flow rate and has nothing to do with pressure changes, so that a stable mixing ratio can be maintained even under pressure changes. dd d:
dd d: Suitable for all foam fire extinguishing systems and can replace pressure proportional mixing The device and balanced proportional mixing device have accurate mixing ratio
dd. ddd: Easy to install and driven by a hydraulic motor without additional power. Compact and lightweight, no pressure vessel required.
dd . ddd: Simple to use, mechanical mixing, wide flow range, wide pressure range, no correction needed
dd . ddd: cost-effective, simple to maintain, regular testing, simple and low maintenance cost during use
