摘要： An auto-fill type float collar assembly is provided. The float collar assembly of the present invention has at least one curved flapper-style valve, preferably constructed of composite, non-metallic material. Each flapper of the present invention has a substantially 90° range of motion, and is closed via a torsion spring. Each flapper is held in the open (or “auto-fill”), position via an external shifting mechanism passing around, rather than through, the central flow bore of the assembly. A floatable actuation ball can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers when desired.

摘要： A valve assembly for use in an inner tube member of a core barrel head assembly positionable within a drill string of a drilling apparatus. The valve assembly works using two separate surfaces A and B and a biasing element with a force FS. When hydrostatic pressure is present forces are created on these surfaces: FA and FB. These forces have a direct relationship with pressure, as an increase in pressure will increase the force and vice versa. The surface areas are designed such that: FA>FB+FS, which will maintain the valve closed while under a predetermined fluid pressure, indicating to the driller that the inner tube has landed. When the driller relieves the fluid pressure and the pressure decreases, the force difference between FA, FB and FS decreases until FA

摘要： This female quick-coupling element for a quick-connect coupling is able to cooperate with a male coupling element. A control ring is able to move in translation along a longitudinal axis between a first position and a second position. A blocking member prevents translation of the control ring as far as its second position. An element for the elastic return of a piston, integral in transverse movement with the blocking member, to its internal position is mounted in a housing of the first coupling element situated outside the housing of the piston, and fluidically isolated from the fluid-flow conduit. The first coupling element comprises transmission means, disposed between the return element and the piston, to return the piston to its internal position.

摘要： A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. This in turn prevents the opening end of the supply/discharge tube from being closed or the opening area from being reduced. As a result, operation performance of the outlet shutoff valve is enhanced.

摘要： An umbrella valve includes an umbrella-valve body having a stem, a flexible umbrella, and a flange. The umbrella and the flange are each attached to, and extend radially outward from, the stem. The flange has at least one fluid passage. The umbrella valve can be placed in a valve housing having a sealing-surface portion. The umbrella, when the umbrella-valve body is placed in the valve housing, is pushed away from the sealing-surface portion under a forward fluid flow and is pushed against the sealing-surface portion under a reverse fluid flow. An umbrella-valve assembly includes the umbrella valve and the valve housing.

摘要： A telescopic snap valve assembly and method of assembling a snap valve with a liquid holding bag in a box fitting. The valve assembly includes a valve member having a lower protruding telescopic end with a raised exterior lower edge. The telescopic end of the valve member is inserted into the center opening of the fitting so that the raised exterior lower edge snaps outward and protrudes from the bottom of the fitting locking the valve member to the fitting. Tight fitting between the telescopic end of the valve and the fitting, with or without a seal member such as O-ring, and the like further seal the valve member to the fitting so that no liquid becomes trapped and/or leaks from the assembly. The assembly can use a ball check valve, and can dispense all types of liquids and fluids such as but not limited to juice with pulp without clogging the valve.

摘要： A back flow prevention device is shown for use in a plastic pipeline for conveying water, sewage, hydrocarbons or other fluids. A valve body features a flow control mechanism which is formed entirely or primarily of plastic materials. The valve body and its opposing ends are formed of a plastic material which is compatible with the plastic material of the existing pipeline, whereby the valve body can be installed in the pipeline in co-axially fashion by directly joining the opposing ends of the body to the opposing mating pipe ends at a selected location within the pipeline.

摘要： A connector housing of a valve-equipped connector is integrally formed from a tube connection section at a first axial side; a pipe insertion section at a second axial side; and a valve housing section between the tube connection section and the pipe insertion section. The valve housing section is formed with an adequately large inner diameter. A main valve body and a compression coil spring for biasing the main valve body to the first axial side so that it abuts the inner surface of the housing are stored in the valve housing section. A cylindrical bushing is fitted to the first axial side of the pipe insertion section of the connector housing, and a valve cap for receiving a second axial end of the compression coil spring is formed integrally at the first axial end of the cylindrical bushing.
