Novel fire extinguishing pipeline system

Abstract

The invention discloses a novel fire extinguishing pipeline system. The novel fire extinguishing pipeline system comprises a main pipeline and at least two auxiliary pipelines, wherein the main pipeline comprises a main flow pipe and a spherical flow dividing body; the spherical flow dividing body comprises a cavity, a first runner and at least two second runners; the main flow pipe communicates with the first runner; the first runner and the at least two second runners communicate with the cavity; the at least two second runners are evenly distributed in the circumferential direction of the spherical flow dividing body, and the second runners and the first runner are obliquely arranged; and each auxiliary pipeline comprises a connecting pipe and a connector, wherein one end of the connecting pipe is connected with the spherical flow dividing body, the at least two connecting pipes and the at least two second runners are arranged in a one-to-one correspondence manner, and the connectoris arranged at the end, deviating from the spherical flow dividing body, of the connecting pipe. According to the novel fire extinguishing pipeline system disclosed in the embodiment, the spherical flow dividing body is adopted for flow dividing, the second runners on the spherical flow dividing body are distributed in a completely symmetric manner, the pressure drop is consistent, and the purpose of uniform outflow is achieved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a novel fire extinguishing pipeline system. Background technique [0002] In large-scale fires, the design of the fire extinguishing pipe network system is very important. The distribution parts and nozzles are the key components of the entire fire extinguishing pipe network system, and the rationality of their structure is closely related to the fire extinguishing performance of the entire system. [0003] In actual life, the phase state of many fire extinguishing media is easily affected by temperature and pressure. For example, the liquid CO2 stored in the tank after pressurized liquefaction, due to the sudden drop of pipeline pressure when the valve is opened, in Joule- Under the Thomson effect, the liquid CO2 flashes instantaneously, and the CO2 flash expansion and phase change endothermic will cause the temperature of the conveying pipeline to drop sharply, ...
