The present invention provides for an integrated valve regulator assembly that comprises an integral body having a base portion that includes an axis for mounting on and coaxially with the neck portion of a pressurized source vessel and an assembly outlet, a defined internal passage in the integral body that extends through and between the base portion of the integral body and the assembly outlet, a sub-atmospheric pressure regulator assembled within the integral body of the integrated valve regulator assembly, an isolation valve positioned within the defined internal passage of the integral body and located downstream from and in communication with the sub-atmospheric pressure regulator, and a filling port disposed between the axis for mounting on and coaxially with the neck portion of the pressurized source vessel and the sub-atmospheric pressure regulator. The present invention further provides for a system for the controlled storage and dispensing of a hazardous material at sub-atmospheric pressure that comprises a pressurized source vessel and the integrated valve regulator assembly of the present invention. The present invention further provides for an additional integrated valve regulator assembly as described with the exception that the pressure regulator utilized is for super-atmospheric pressure conditions and also a system that comprises a pressurized source vessel and the integrated valve regulator assembly that includes a super-atmospheric pressure regulator.
Abstract:
An ullage tank in a vertical cryogenic storage vessel that can store a liquefied gas is described. The ullage tank includes a hollow member. The ullage tank has at least one opening that allows communication between the ullage tank and an inner vessel of the vertical cryogenic vessel. The hollow member has a first open end and a second open end. The hollow member forms a vertically disposed passage through the ullage tank. The first open end and the second open end are in communication with the inner vessel. Related methods, apparatuses, systems, techniques and articles are also described.
Abstract:
A gas fuel supply apparatus includes: first and second mouthpiece attachment sections capable of detachably attaching thereto mouthpieces of first and second gas containers and provided in communication with each other; and first and second check valves provided in a communication passage, communicating between the mouthpiece attachment sections, in corresponding relation to the first and second gas containers. The first and second check valves prevent a gas fuel, let out from any one of the first and second gas containers, from flowing into the other of the gas containers.
Abstract:
A safety valve device has a safety valve body and is configured to open at a temperature of or over a preset reference temperature. The safety valve device also includes a gas flow path arranged to make a flow of hydrogen flowing out of a hydrogen tank via the safety valve body in a valve open position, and a discharge pipe configured to have a hydrogen discharge opening and arranged to discharge the hydrogen flowing through the gas flow path to the outside. The hydrogen discharge opening of the discharge pipe is formed to discharge the hydrogen in an oblique direction relative to a direction of an axial center of the gas flow path. The discharge pipe also has a groove formed to apply an input rotational force to the discharge pipe and thereby rotate the discharge pipe around the axial center of the gas flow path.
Abstract:
An apparatus and method for constructing a cryogenic storage tank (700) having a welded inner tank (702), an outer shell (704) surrounding the welded inner tank (702), a concrete foundation (728) comprising a raised portion (752), a plurality of cellular glass blocks (734) positioned directly on top of the raised portion (752) of the concrete foundation (728), a leveling course of concrete (736) poured on top of the uppermost layer of the plurality of cellular glass blocks (734), and a mounting apparatus (718) affixed to the concrete foundation (728), where the welded inner tank (702) is positioned on top of the leveling course of concrete (736) and the outer shell (704) is affixed to the mounting apparatus (718) at locations around the periphery of the outer shell (704).
Abstract:
A closure is shown for an equipment sub. A closure door is carried by a sub body and movable thereto between open and closed positions for providing access to a pressure vessel. Various improvements are disclosed including a new mechanism for positioning wedge shaped arcuate segments between the door and the sub body, a retainer mechanism for guiding movement of cross bars, a split hinge adjustment mechanism for adjusting planarity and concentricity between the closure door and the sub body, an increased annular wall body thickness region surrounding the sealing surface for reducing warpage during welding, a pressure lock rod member which also engages a combination of cross bars and a crank for driving the cross bars, and a pry bar that can facilitate better manually operated leveraging of the closure door.
Abstract:
A fuel can adapter has a threaded section for threadly engaging with a fuel device. Particularly, the fuel device has a threaded joint for engagement with the thread section of the fuel can adapter. In addition, this threaded joint can be used to connect a fuel can with a thread head, such that fuel in the fuel can can flow to the fuel device. With the fuel can adapter, a fuel can with a head, which does not have a threaded head but has a flange extending circumferentially thereon, is adapted to connect to the fuel device, such that fuel in the fuel can can flow to the fuel device.
Abstract:
The present invention relates to a pressure vessel (1) for a high pressure press comprising at least a first sub-cylinder (4) and a second sub-cylinder (6), which are axially connected to form a cylinder body (2) for enclosing a high pressure medium, and a sealing arrangement arranged at the inner wall of the cylinder body for sealing the joint (3) between the first and the second sub-cylinder (4, 6) against leakage of the pressure medium. The sealing arrangement is comprising a ring shaped sealing band (18), a first circumferential protruding flange (30), which is arranged on the inner wall of the first sub-cylinder and which axially extends from the joint (3) and away from the second sub-cylinder (6), and a second circumferential protruding flange (32), which is arranged on the inner wall of the second sub cylinder (6) and which axially extends from the joint (3) and away from the first sub-cylinder (4). The sealing band (18), in mounted position, is located concentrically within the first and the second protruding flanges (30, 32) such that it in a radially pre-stressed manner abuts against the first and second protruding flanges (30, 32) and sealingly overlaps the joint (3) between the first and the second sub-cylinder (4, 6). The sealing arrangement further comprises a first circumferential mounting space (51), which is arranged in the inner wall of the first sub-cylinder (4) and which axially extends from the first protruding flange (30) and away from the second sub-cylinder (6), for facilitating exchange of components of the sealing
