The steering valve system is one of the subsystems with large dead weight in the aircraft, and plays a crucial role in the direction control and the combat command of the aircraft. The cable assembly and the electrical interface used by the traditional steering valve generally adopt stainless steel pipes in order to meet the stress requirement, and the dead weight and the angle change are unavailable so that the space of a machine body is limited. In addition, the traditional stainless steel welding mode has large heat affected zone, slow welding speed, easy deformation and uneven appearance of the section of the welding line. Therefore, new stainless steel forms and welding techniques are urgently needed on the premise of meeting the aviation installation environment.

The cable component based on the aviation steering valve system can meet various flight environment requirements.
The technical scheme adopted by the invention is as follows: a cable assembly based on an aviation steering valve system, characterized in that: the high-temperature-resistant double-twisted shielding wire comprises two sockets, two stainless steel corrugated pipes, a three-way pipe, an elbow, a connecting flange, a high-temperature wire, a double-twisted shielding wire, a shielding net and a high-temperature-resistant heat-shrinkable tube, wherein two ends of a horizontal pipe of the three-way pipe are respectively connected with the two sockets through the two stainless steel corrugated pipes, a vertical pipe of the three-way pipe is a straight pipe, the straight pipe is connected with the connecting flange at the corresponding position of a steering valve plug inside an airplane through the elbow, the high-temperature wire is coated with the double-twisted shielding wire and penetrates through the three-way pipe, the high-temperature wire and the double-twisted shielding wire are connected with the two sockets.
The three-way pipe, the elbow and the connecting flange are made of 316 stainless steel.
The socket comprises a base body and a tail cover, the base body is externally sleeved with a connecting nut in a limiting and sealing manner through a retainer ring and a sealing ring, a slotted conical section set screw is arranged in the socket end of the connecting nut, the tail end of the connecting nut is connected with the tail cover, and the tail cover is connected with the stainless steel corrugated pipe in a seamless welding manner.
The stainless steel corrugated pipe comprises a joint and a corrugated pipe, and the tail cover is connected with the joint in a seamless welding mode.
The stainless steel corrugated pipe is connected with the three-way pipe in a seamless welding mode.
After the technical scheme is adopted, the invention achieves the beneficial effects that:
1. The dead weight is lightened, and the impact force is resisted. The stainless steel corrugated pipe component adopts a 316L corrugated pipe which is different from a conventional straight-through type corrugated pipe, so that the strength is ensured, the weight of the cable component is obviously reduced, and meanwhile, the impact force generated in flight is reduced.
2. The reliability and the stability are improved. The welding seam section of the stainless steel corrugated pipe assembly adopts a laser welding technology, and 360-degree seamless welding ensures that no intervention of water vapor, sand dust and the like in the flying process influences the reliability and stability of the airplane steering valve system.
3. The installation space is optimized, and the installation is simplified. The corrugated pipe of the stainless steel corrugated pipe adopts a 316L corrugated pipe, the outer diameter phi is 22mm, the inner diameter phi is 16mm, the wall thickness of a single surface reaches 3mm, the bending angle is not less than 60 degrees, the bending in different directions can be realized when the cable assembly is installed, and the requirement of aviation simplification is met.
