This creation is a kind of breathing pipeline adjustment valve arrangement,When the oxygen of its supply is imported through air inlet pipe,Turn valve deck makes its interior screw part,Position screw part set by opposite what pressure release valve seat is in locking or unscrews state,The then inner wall of hollow guide post lower section set by valve deck when what locks or unscrews state,The bottom side of the cone column of pressure release set by opposite what pressure release valve seat is in closed abutting or contactless state,Meet oxygen supply demand to control the pressure of gas importing,The adjusting of oxygen supply pressure can be carried out via simply screwing or unscrewing valve deck,Effectivelying prevent oxygen-supplying amount is more than that patient organ bears and generates danger,The effect of to reach ease of use and good safety in utilization.本創作係一種呼吸管路調整閥結構，其供應之氧氣經進氣管導入時，旋動閥蓋使其內螺合部，相對於洩壓閥座所設定位螺合部呈鎖緊或旋鬆狀態，於鎖緊或旋鬆狀態時則閥蓋所設中空導柱下方之內壁，相對於洩壓閥座所設洩壓錐柱之底側呈密閉緊貼或非接觸狀態，以控制氣體導入之壓力符合供氧需求，經由簡易旋緊或旋鬆閥蓋即可進行供氧壓力之調節，有效防止供氧量超過患者器官負擔而產生危險，以達使用便利性及使用安全性佳之功效。
