摘要: High-pressure cylinder having an inner core in plastic material and a surface covering of one or more layers of composite material, partially incorporating a nozzle in metal material attached to the upper terminal portion of the neck of the core shaped to receive at least one accessory, such as a tap or a valve. The nozzle is composed of an inner element and an external element screwed one to the other to tighten on the neck of the core. The neck of the core has a slight narrowing of diameter starting from its mouth, such as to determine an internal conical surface suitable for coupling with a corresponding external conical surface of the internal element of the nozzle, and an external conical surface suitable for coupling with a corresponding internal conical surface of the external element of the nozzle.

摘要: A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

摘要: A method for making a cylinder for reactive gas mixtures in the calibration gas segment of the compressed gas market includes cutting a stainless steel tube to a desired length. First and second axial end portions of the cut tube are swaged. A spud is connected to the first swaged axial end portion of the cut tube. A base is connected to the second swaged axial end portion of the cut tube. The cylinder for reactive gas mixtures in the calibration gas segment of the compressed gas market includes a stainless steel tube having first and second swaged axial end portions and a central portion extending between the first and second swaged axial end portions. The spud is connected to the first swaged axial end portion of the tube. The base is connected to the second swaged axial end portion of the tube.

摘要: A high-pressure container having a liner and a composite layer for reinforcing a perimeter of the liner includes: a cylinder part foiled along the axial direction of the high-pressure container; and dome parts fastened to both ends of the cylinder part to enclose the high-pressure container. The composite layer formed on the cylinder part is formed by a plurality of hoop layers and helical layers overlapped alternately. A hoop layer disposed closer to the liner has a thickness greater than that of a hoop layer disposed farther from the liner so that a thickness of the hoop layers decreases as a distance from the linear increases.

摘要: A method of manufacturing a reinforcement layer comprises a preparatory step of preparing to-be-wound fiber, and a formation step of forming an uncured sheet layer including multiple layers of the to-be-wound fiber stacked on an outer circumferential surface. In the formation step, the to-be-wound fiber is wound on the outer circumferential surface in such a manner that, regarding an outer layer of the uncured sheet layer and an inner layer of the uncured sheet layer closer to the outer circumferential surface than the outer layer and adjacent to the outer layer in a stacking direction of the to-be-wound fiber, two end portions of the outer layer are located between two end portions of the inner layer in an axis direction extending along a center axis of a winding target member.

摘要: A structure whereby a piping nozzle can be simply attached to a tank body is disclosed. A cylinder of a nozzle body is inserted through the interior and exterior of the tank body via a nozzle body insertion hole in the tank body. A skirt is provided on an end portion of the cylinder, and expands annularly from the end portion of the cylinder in the interior of the tank body. A sealing member is interposed between an inner surface of the tank body and the skirt around the nozzle body insertion hole. A spacer member is disposed on an outer surface of the tank body around the cylinder. By tightening a nut on a male screw of the cylinder of the nozzle body, a portion of the tank body around the nozzle body insertion hole is sandwiched by the skirt of the nozzle body and the spacer member.
