AI Technical Summary
Technical Problem
The cage-type safety valve integrated in the fuel pump of the existing aviation fuel system occupies a large space, has insufficient flow capacity, and is not suitable under special conditions.
Method used
The embedded safety valve structure includes a cage structure, valve seat, valve core, optical shaft, spring, and safety valve plug. Through optical shaft limiting and spring buffering, combined with PTFE gaskets and porous structure, the valve core movement trajectory is optimized to reduce hydraulic shock.
Benefits of technology
It improves the stability and flow capacity of valve core movement, reduces the damage of hydraulic shock to other structures, and extends the service life of the safety valve.

Abstract
The utility model discloses an embedded safety valve structure in aviation fuel system oil pump, including cage type structure, it is located the lower part of safety valve, valve seat, the valve seat is located cage type structure's tail end, valve core, valve core is located the inside of valve seat and along the axial direction of valve seat and slides, optical axis, one end of optical axis is inserted into the inside of valve seat and is fixedly connected with valve core, the other end of optical axis extends to the outside of valve seat and is fixedly connected with safety valve plug, spring, the spring is used for buffering to valve core and it sets up between valve seat and safety valve plug. Embedded safety valve structure in aviation fuel system oil pump provided in the utility model because of the limiting effect of optical axis, the force of spring is stable, and pressure fluctuation is stable and controllable, because safety valve opening means the invasion of high pressure medium, and the increase of flow area can also effectively reduce the damage of hydraulic impact to other structures, and the service life is long.
