摘要： An apparatus, system, and method are disclosed for a gas chromatography (GC) system with a check valve. The check valve is situated downstream from the electronic flow control module and upstream of the injector. When a sample is volatized in the injector, the check valve closes into a checked position and prevents solvent and sample from backing into the gas delivery line. In certain embodiments, the check valve has a conical plug that fits into a seat that has an aperture. When the conical plug is depressed, the conical plug engages the sides of the aperture and seals the check valve, preventing solvent and sample from backing through the check valve. In certain embodiments, the change in pressure caused by over-pressurization in the injector, combined with the force applied by a spring on the conical plug, depresses the plug such that it seals the aperture.

摘要： A connector housing of a valve connector integrally has a tube connecting portion on one axial end thereof, a pipe inserting portion on the other axial end thereof, and a valve housing between the tube connecting portion and the pipe inserting portion. A valve housing houses a valve body and a compression spring that biases the valve body in an axial direction into abutment with a housing inner surface. Anti-rotation ribs are provided integrally on an inner peripheral surface of the valve housing. The anti-rotation ribs abut the valve body so as to restrain the valve body from rotating.

摘要： A fluid flow control valve is disclosed. This valve includes a housing which defines a central passageway having fluid inlet and fluid outlet openings. A pressure responsive element is disposed within the passageway for selectively opening and closing the inlet opening to fluid flow in response to pressure exerted thereon at the inlet opening. A mechanism is provided within the passageway for exerting a bias force against the pressure responsive element sufficient to close the inlet opening to fluid flow absent a pre-established level of pressure exerted on the pressure responsive element in opposition to the bias force. Finally, a retainer device is positioned for removably securing the pressure responsive element and bias force exerting mechanism within the passageway.

摘要： A safety relief valve is provided that comprises a body comprising a chamber therein and an inlet and an outlet, the inlet comprising an inlet valve seat; a disk member closable on the inlet valve seat; and a mechanism in the body biasing the disk member to rest on the inlet valve seat with a set force such that when the pressure in the inlet exceeds a set pressure resulting from the set force, the disk member is lifted from the inlet valve seat, the mechanism comprising a combination of a coil spring and one or more disk springs stacked in series with the coil spring.A method of preparing a coil spring for use in a pressure relief valve comprises measuring the spring rate of the coil spring and; modifying the spring so as to modify its spring rate to be within ±2% of a desired spring rate.
