The invention provides an integrated breather valve and an aircraft fuel tank, and relates to the technical field of aircraft fuel tanks, the integrated breather valve comprises a valve body, a limiting part is arranged in a valve cavity of the valve body, a first air channel and a second air channel are formed in the side wall of the valve cavity, and the first air channel communicates with the upper end and the lower end of the valve cavity through a first branch and a second branch correspondingly; the first valve element and the second valve element are located on the two sides of the limiting part correspondingly, and a third air channel is formed in the second valve element; the first elastic component and the second elastic component are arranged between the first valve element and the limiting part and between the second valve element and the limiting part respectively; when the first valve element moves in the direction of compressing the first elastic component, the first air channel can communicate with the first branch through the valve cavity, and when the second valve element moves in the direction of compressing the second elastic component, the other end of the third air channel can communicate with the second branch. The problem that in the prior art, air pressure inside and outside an aircraft fuel tank is difficult to automatically regulate and control through a valve is solved.
本发明提供一种集成式呼吸阀及飞行器燃油箱,涉及飞行器燃油箱技术领域,包括:阀体,阀体的阀腔内设置有限位部,阀腔的侧壁的内部开设有第一气道和第二气道,第一气道通过第一分支和第二分支分别与阀腔的上端和下端连通;第一阀芯和第二阀芯,分别处于限位部的两侧,第二阀芯内开设有第三气道;第一弹性部件和第二弹性部件,分别设置在第一阀芯与限位部之间和第二阀芯与限位部之间;当第一阀芯向压缩第一弹性部件的方向移动时,第一气道能够通过阀腔与第一分支连通,当第二阀芯向压缩第二弹性部件的方向移动时,第三气道的另一端能够与第二分支连通;解决现有技术中的阀门难以实现自动调控飞行器燃油箱内外气压的问题。
