Abstract

The invention discloses flow feature test equipment for a fire extinguishing system pipe network. The equipment comprises a test rack, a fire extinguisher hanging rack, a fire extinguisher, an electromagnetic valve, a conveying pipeline, a tail-end nozzle, a test interface, a pressure sensor, a temperature sensor, a signal conditioning and data collecting module, an industrial control computer, acontrol panel and a flow field visualization chromatographic analysis unit. Compared with the prior art, the equipment has the advantages that the equipment can acquire the flowing and conveying information of a fire extinguishing agent in a pipeline system, confirm the influence of various pipeline parts on a flow field and provide technical support for the pipe network design of a novel fire extinguishing system.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing system pipe network design, in particular to an experimental device for the flow characteristics of the fire extinguishing system pipe network. Background technique [0002] The flow characteristics of the fire extinguishing pipeline are related to the effectiveness of the fire extinguishing system. The current design of the fire extinguishing system is based on relevant fitting formulas measured by previous international experiments, including the calculation of parameters such as flow, pressure, and injection time in the fire extinguishing system pipeline. It should be pointed out that these fitting formulas are only obtained based on the flow parameters of the fire extinguishing agent under specific experimental conditions, and the flow rate and other parameters given are all constant, which cannot accurately reflect the real unsteady injection process of the fire extinguishing agent...
