Abstract

A positive-pressure automatic spume proportionality mixer systems includes pressure water pipeline, spume pipeline and mixer pipeline. There are at least spume tank, spume purification apparatus, ram-type pump, spume application valve ball and back valve setup at the spume pipeline with spume tank at the beginning, the out spout pipeline of back valve joins with pressure water pipeline to mixer pipeline. A flow rate sensor is set at the aforementioned mixer pipeline and connects to control module with wires, the control module connects with parameter input and display module and machine controller connecting with electric motor drive ram-type pump. The system can implement whole automatic control spume mixing proportion with simple operation, accurate adjustment, stabilizing and reliable operation activity.

Description

Technical field [0001] The invention relates to the technical field of fire safety facilities, in particular to a positive pressure type automatic foam ratio mixing system. Background technique [0002] The foam fire truck mixes water and foam in a certain proportion through a fire pump and a foam ratio mixing device, and then sprays it out through a foam fire monitor or foam fire gun, quickly covering the burning material, and extinguishing the fire through isolation and cooling. In order to achieve the best fire extinguishing effect, the mixing of water and foam must meet a certain proportional relationship. The proportional mixing device equipped with foam fire trucks is used to ensure that the foam mixing meets the above proportional relationship. [0003] At present, the commonly used foam ratio mixing devices are: [0004] 1) Ring pump type proportional mixer. [0005] Because the ring pump type proportional mixer uses the Venturi effect, the pressure water generated by the wat...
