    Abstract: A pressure relief valve (50) in a triple offset butterfly valve configuration. It has a body (52), pallet (82), pallet assembly (54) and closure mechanism (56) with a lever arm (70) providing mechanical advantage upon a cam (66) which aids in the closing of the valve. The valve (50) relies upon a shear pin (80) which can be machined to alter the opening pressure of the valve. The pallet (82) is secured to the pallet assembly (54) by a plurality of adjustment fasteners (88) and retainer fasteners (90) which can be adjusted to provide an effective seal on the valve (50). A valve seal (94) has one or more layers of graphite (98) and metal. (100) A pallet seal (102) is captured in a groove (104) in the pallet (82) which restricts radial movement of the pallet seal (102). The valve seal (94) is captured between a retainer and the pallet seal (102).

    Abstract: A floor drain valve (10) in the form of a flapper valve, which includes a pressure relief conduit (34) to equalize pressure across the valve and permit unrestrained draining of fluid through the valve. The pressure relief conduit (34) is equipped with a valve member (30) which opens upon a predetermined pressure on the downstream side of the valve (10), and may further comprise a ball valve (24) to ensure that gas can escape through the conduit but liquids are prevented from it. The valve (10) may be fixed into a drain pipe by means of an expansion ring (80, 82, 84)

The fluid controller includes a rim that defines a fluid passage for a flow of fluid inflation and deflation of an inflatable bladder. A diaphragm is configured to seal the fluid passage, and the self sealing valve also includes at least one extension configured to extend over the diaphragm to limit a deflection of the diaphragm in a direction away from the interior of the inflatable bladder to maintain a substantially fluid-tight seal between the diaphragm and the rim under increased pressure within the inflatable bladder.

    Abstract: A check valve is disclosed that includes a base having a porous first surface, a keeper coupled to the base, and a flexible leaf with a first section that is fixedly coupled between the keeper and the base and a second section that is cantilevered from the first section. The leaf has a first position when the leaf is fully in contact with the base and a second position when the leaf is fully in contact with the keeper. The leaf is configured to sealingly cover the porous first surface when the leaf is in the first position. The leaf is in an unstressed configuration when in the first position, and a maximum stress in the leaf is less than the yield stress when the leaf is in the second position. The check valve is particularly suited for use with cryogenic fluids such as liquid hydrogen and liquid oxygen.

    Abstract: The problem of flappers that will not close due to high velocity gas rushing past and creating a vortex that has zones of high pressure pressing the flapper against the force of the torsion spring is reduced or overcome with modifications in the passage through a subsurface safety valve so as to reduce the intensity of the vortex to allow the torsion spring to pivot the flapper to closed position. Various shapes are inserted adjacent the flapper base to create turbulence to minimize or prevent the vortex and the associated pressure increases that would otherwise prevent flapper closure with the flow tube retracted. Inserts that create turbulence are placed in a recess that in part holds the flapper when it is rotated to the open position.

    Abstract: A backflow-prevention system that substantially prevents contaminant backflow at a treatment site. The system includes a fluid ejector tube for insertion into the patient's mouth and for removal of fluids when a threshold vacuum pressure is applied. A backflow prevention device receives fluid from the fluid ejector tube and includes an internally positioned valve. The valve prevents contaminant backflow upon release of the vacuum pressure or a reduction in the vacuum pressure. Upon application of vacuum pressure, the valve moves into an open position to allow fluid flow away from the treatment site. The system can also include a disposable cover member that extends over at least portions of the fluid ejector tip, the backflow prevention device, and other features such as an ON/OFF valve assembly of a suction system. Similar principles of backflow prevention can be applied to fluid dispensers (e.g., liquid soap dispensers) wherein backflow of the fluid into the fluid storage container is undesirable.
