<p>PROBLEM TO BE SOLVED: To prevent unexpected bounding and flying of a hose occurring during separation of a rapid disconnect release coupling with which high compressed air is connected is prevented from occurring by arranging an exhaust process in a semilocked state. SOLUTION: A ventilation valve hole 42 for main ventilation and an exhaust valve hole 44 for exhaust are formed in a spool valve body 4 slid in a socket body 2. Three of six-ball group arranged at the tip of the socket body 2 serving as an engaging means with a plug 9 are released from engagement through regulation of movement of a lock ring 7 contained and mounted in an annular state. Coupling of the plug is brought into a semi-lock state and exhausted through an exhaust valve hole 44. Further, the exhaust valve hole is eliminated, a ventilation passage communicated with the ventilation valve hole is formed in a valve seat ring 5, and this constitution may perform exhaust in a semilocked state.</p> |
