The invention relates to the technical field of aircraft testing, in particular to a valve type ventilation device for aircraft testing. The valve type ventilation device for aircraft testing comprises multiple sub-pipelines connected in a full-length welding manner and a valve arranged in one of the sub-pipelines, each of the multiple sub-pipelines comprises a pipeline body, an anti-condensation pad filled in the pipeline body and a reinforcing assembly for reinforcing the pipeline body. The ventilation device is reasonable in design, the problem that condensation dew is generated due to the fact that the temperature difference between the inner side and the outer side of the pipeline is too large can be effectively solved, and the ventilation device can tolerate the extreme environment and severe cold and hot alternation and has good safety performance; and moreover, the sub-pipelines are connected in a full-length welding manner, so that the pipelines have high sealing performance, and meanwhile, the strength and rigidity of the overall structure of the ventilation device are improved through the reinforcing assemblies, and the reliability of the ventilation device is greatly enhanced.

    本发明涉及飞机测试技术领域,具体涉及一种飞机测试用阀门式通风装置,包括多个采用满焊的方式连接而成的子管道以及设置在其中一个所述子管道内部的阀门;多个所述子管道均包括管道本体,填充在所述管道本体内部的防凝露垫以及用于加固所述管道本体的加固组件;本发明设计合理,能够有效地防止管道内、外两侧温差过大产生冷凝露水的问题,使得通风装置能够耐受极端环境及冷热剧烈交替,具备较佳的安全性能;并且,本发明子管道之间采用满焊的方式进行连接使得管道具备较高的密封性能,同时通过加固组件提高了通风装置整体结构的强度和刚度,极大的增强了通风装置的可靠性。
