Push-to-connect coupler with interlocking three-way valve |
摘要 |
<p>A push-to-connect coupler including an interlocking three-way valve that enables coupling and uncoupling with respect to a mating nipple only when the coupler is in a vent mode. The coupler is characterized by a unique integration of a manually operated three-way ball valve that vents the coupler down to atmospheric or reduced pressure prior to coupling or uncoupling and preferably to a recovery line, a push-to-connect sleeve locking mechanism which interlocks with the manually operated handle of the three-way valve and whose operation is visibly obvious to the user, and an internal valve mechanism that prevents the free flow of media should the coupler become miscocked.</p> |
