Estimating the term…
Quick disconnect devices for high pressure fluid transfer, and associated systems and methods are disclosed. A representative quick disconnect system includes a first connector and a second connector. The second connector can have an opening sized and shaped to receive a first end of the first connector. The second connector can include a poppet positioned to open the first connector when the first connector is connected to the second connector. The second connector can include an inner sleeve moveable between a first position wherein the poppet head forms a fluid-tight seal with the annular seat of the inner sleeve, and a second position wherein the second end portion is open to permit fluid flow through the end portion of the inner sleeve. In some embodiments, the inner sleeve is pressure balanced in every direction.
A quick disconnect (QD) system comprising a poppet having a poppet head to fit within a first cavity of a piston head and having a step on a side surface of the poppet head, the step to seal an engagement between the poppet head and a frustoconical and/or chamfered surface of the piston head, wherein the poppet head is isolated, at least at its mating surface with the piston and at its longitudinal side surface, from fluid when a fluid coupling is established in the QD system.
A poppet for a quick disconnect (QD) system, the poppet comprising a poppet head to fit within a first cavity of a piston head and comprising a step on a side surface of the poppet head, the step to seal an engagement between the poppet head and a frustoconical and/or chamfered surface of the piston head, wherein the poppet head is isolated, at least at its mating surface with the piston and at its longitudinal side surface, from fluid when a fluid coupling is established in the QD system.
A piston for a quick disconnect (QD) system, the piston comprising a piston head and a first cavity of the piston head and comprising a frustoconical and/or chamfered surface of the piston head, wherein the first cavity is to receive a poppet head of a poppet which fits within the first cavity, wherein the frustoconical and/or chamfered surface is to seal an engagement of the piston head with the poppet head at a step on a side surface of the poppet head, and wherein the poppet head in the first cavity is to isolate the poppet head, at least at its mating surface with the piston and at its longitudinal side surface, from fluid when a fluid coupling is established in the QD system.
