AI Technical Summary
Technical Problem
Traditional O-rings are prone to micro-extrusion under extreme pressure, resulting in insufficient sealing reliability in ultra-high pressure systems.
Method used
It adopts a trapezoidal double-layer sealing structure and spiral reinforcement design, including an outer threaded elastic block, a first sealing ring, a second sealing ring, an inner threaded rubber extrusion ring, a miniature flange, and a positioning boss, which improves the sealing performance through multiple designs.
Benefits of technology
This effectively improves the tightness and sealing of the connection between the hydraulic solenoid valve housing and the solenoid valve body, ensuring reliable sealing under high pressure.
