Abstract: A fluid system component is provided that includes first and second elements configured to be removably engaged with each other and defining a fluid passageway when engaged. The first element defines three grooves, each of which includes a terminal portion. Correspondingly, the second element includes three engagement members each of which is configured and arranged to be received in, and travel along, a corresponding groove. The presence of a predetermined line pressure in the fluid passageway forces each engagement member into the terminal portion of the corresponding groove, so as to substantially foreclose disengagement of the first and second elements until the fluid pressure in the fluid passageway has reached a predetermined magnitude.

Abstract: This disclosure is concerned with fluid system components. In one example, a quick disconnect valve assembly includes first and second valve elements configured to releasably engage each other. Each valve element includes a housing that defines a valve seat and a fluid passageway. A plunger is disposed within each housing and arranged for selective engagement with a corresponding valve seat. Each plunger is biased into a sealing engagement with the valve seat by a resilient element disposed within the housing. Consequently, the fluid passageway of each valve element is closed off when the first and second valve elements are separated from each other. When the valve elements are engaged, the respective biases associated with the plungers counteract each other to the extent that each plunger is lifted off the corresponding valve seat and fluid communication is established between the respective fluid passageways of the first and second valve elements.

Abstract: A gear operated coupler is provided for coupling and uncoupling mating first and second coupling portions of a piping system component. A sleeve with an attached spur gear includes threads that engage the first coupling portion, and the sleeve slidingly receives the second coupling portion. The coupling portions are maintained in a metal-to-metal seal arrangement by a compensation ring in the sleeve. A pinion plate, carrying an associated pinion gear, is attached to the second coupling portion so that the pinion gear engages the spur gear. A torque applied to an operating nut connected to the pinion gear shaft causes the pinion gear and spur gear to rotate. Depending on the direction of rotation of the pinion gear, the threads of the sleeve advance the first coupling portion toward the second coupling portion until the two are coupled, or the first coupling portion is retracted from the second coupling portion.

Abstract: A product transfer device is provided that includes telescoping tubular arm sections that collectively define a fluid passageway and are arranged so that a terminal arm section has the smallest diameter, while the diameters of the succeeding arm sections are increasingly larger. Piston seals in adjacent arm sections cooperate to define a chamber. A product transfer valve and isolation valve control the flow of product through the product transfer device. Pressurization of the passageway extends the arm sections and an actuator device opens the product transfer valve when the transfer arm contacts a container bottom. Pressurization of the chamber causes retraction of the arm sections so that the exterior of each arm section is wiped clean by the piston seal of the arm section into which that arm section is retracted. Retraction of the arm sections also operates a securing device that automatically shuts the product transfer valve.

Abstract: A fluid system component is provided that is implemented as a section of metal pipe having a predetermined wall thickness and including a sacrificial element intended to preferentially fail upon the occurrence of certain predefined conditions. The sacrificial element takes the form of a window of predetermined geometry that covers an opening defined in the wall of the pipe. The window is configured to have a thickness substantially less than the wall thickness of the pipe, but nonetheless sufficiently great that the window remains materially unaffected by normal system operating conditions to which it is exposed. When the window is exposed to a pressure differential of predetermined magnitude, typically much greater than normal system operating pressures, the relatively thin window ruptures and permits the pressurized material, either inside or outside the pipe, to flow through the rupture.

Abstract: A fluid flow management system that includes a feedback system in communication with a fluid system component having discrete elements that, when joined together, define a joint and chamber. The fluid flow management system further includes a feedback fluid source in fluid communication with the chamber and with a pressure transducer. The feedback fluid source, transducer, and chamber collectively define a substantially closed system so that fluid introduced by the feedback fluid source eventually reaches static equilibrium. Separation of, or relative movement between, the discrete elements of the fluid system components permits fluid to escape the chamber, thereby causing a pressure change that is detected by the pressure transducer. The pressure transducer then generates and transmits a signal indicating a loss of joint integrity. The signal may be used to aid in the implementation of various actions concerning the system wherein the fluid system component is employed.

Abstract: A valve assembly with an automatic check valve feature and automatic disassembly feature. The valve assembly includes an actuating mechanism which keeps the valve gates open, establishing fluid communication. The fluid checking feature operates when the valve assembly is disassembled. When the valve assembly disassembles, the check valves automatically close. The valve assembly can be disassembled manually or automatically. The automatic disassembly feature includes a collar and breakable link assembly, which keep the valve assembly in sealing engagement. Upon a predetermined force, the breakable link assembly fails, releasing the collar from the valve assembly and effecting disassembly of the valve assembly.
