The oil receiving valve comprises a supporting valve body, a pressing element and a pressing adjusting element, the pressing adjusting element and the supporting valve body are connected, the connecting position of the pressing adjusting element and the supporting valve body can be adjusted, and an elastic piece is arranged between the pressing adjusting element and the pressing element. When fuel oil is injected into the oil tank, acting force is applied to the pressing element and the sealing element, the pressing element compresses the elastic piece to slide in the direction of pressing the adjusting element, the sealing element is separated from the oil injection port, and the fuel oil introduced from the oil injection port passes through the oil passing hole communicated with the oil injection port and is injected into the oil tank. And after oil injection is completed, the acting force applied to the pressing element and the sealing element is removed, and the oil injection opening is plugged again. The connecting position of the pressing adjusting element and the supporting valve body is adjusted, the compression state of the elastic piece can be changed, and therefore the acting force for pushing the pressing element and the sealing element is adjusted, the oil receiving valve can meet the engineering requirements of different aircraft oil tanks, and the adaptability of the oil receiving valve is improved.

    本发明公开一种受油阀,包括支撑阀体、压紧元件和压紧调整元件,压紧调整元件与支撑阀体相连且二者的连接位置能够调整,压紧调整元件与压紧元件之间设置弹性件。向油箱注入燃油时,向压紧元件和密封元件施加作用力,压紧元件压缩弹性件朝向压紧调整元件的方向滑动,密封元件与注油口分离,由注油口通入的燃油,经过与注油口相连通的过油孔,注入油箱;注油完成后,撤去施加在压紧元件和密封元件上的作用力,重新封堵注油口。调整压紧调整元件与支撑阀体的连接位置,能够改变弹性件的压缩状态,从而调节推动压紧元件以及密封元件的作用力大小,以使受油阀满足不同飞行器油箱的工程要求,提高受油阀的适应性。
