Problems solved by technology
[0002] Before the flight, it is necessary to check the quality of various oils inside the aircraft. Different oils will flow out through the fuel selector. Since the fuel selector / oil filter is generally arranged according to the shape of the aircraft, often the oil inlet of the oil drain device After aligning with the fuel selector, the oil outlet will interfere with the shape of the aircraft, making the oil drain device unusable, and there is an oil leakage problem during the oil drain process.
At present, there is no effective oil discharge device for general-purpose aircraft in China, which can flexibly discharge oil to any part of the fuel system, and can effectively seal after oil discharge to prevent oil leakage

The invention relates to a self-sealed valve device for oil draining. The device comprises a shell (1), a connector pipe (2), a valve element (3), a top piece (4), a spring (5) and a valve seat (6). An oil inlet (101) and an oil outlet (102) are formed in the shell, and the angles of the oil inlet (101) and the oil outlet (102) are preset, and therefore an oil draining device can more adapt to the shape of the oil draining position; and on the fuel passing path, a spring (5) is arranged between the valve element (3) and the valve seat (6), and an oil path can be sealed by itself, and the problem of oil leakage in the oil draining process can be solved. The oil draining device has the beneficial effects of being simple in structure, light, high in reliability, convenient to mount and maintain and the like.
Description
technical field [0001] The invention belongs to the field of aviation technology, in particular to an oil discharge self-sealing valve device. Background technique [0002] Before the flight, it is necessary to check the quality of various oils inside the aircraft. Different oils will flow out through the fuel selector. Since the fuel selector / oil filter is generally arranged according to the shape of the aircraft, the oil inlet of the oil discharge device is often After aligning with the fuel selector, the oil outlet will interfere with the shape of the aircraft, making the oil drain device unusable, and there is an oil leakage problem during the fuel drain process. At present, there is no effective oil discharge device for domestic general-purpose aircraft that can flexibly discharge oil to any place in the fuel system, and can effectively seal after the oil discharge to prevent it from leaking. Contents of the invention [0003] The purpose of the present invention is ...
