Abstract:
The present invention discloses a small sized and high-pressurized container for preventing explosion. According to the preferred embodiment of the present invention, a can body has a shape of cylinder for containing high-pressurized product therein. An upper body, which has a dome-like shape, is connected to the top of the can body by seaming or welding, and comprises a groove around its lower part. A valve is mounted on the top of upper body, and discharges high-pressurized gases or liquids, which exists in the inside of the container. A plurality of scores is configured at the bottom of the groove of the upper body, in order to discharge an overpressurized product and prevent bursting or explosion of the container. The scores weaken the resistance of the upper body, so in the event of that a certain internal overpressure is applied, the upper body firstly deforms outwardly and then one or more scores are fractured, and lastly the overpressurized product is discharged from the scores.
Abstract:
A container for transporting and storing hazardous materials such as Chlorine includes a cylindrical body having end caps. The end caps are welded to the body to form a pressure vessel. The end caps have a peripheral edge that is recessed with respect to the ends of the body to protect the weld against damage from impact. The configuration of the juxtaposed components forms a lap joint that can be affixed together by a fillet weld.
Abstract:
An apparatus for controlling the discharge of pressurized fluids from the outlet of a high pressure cylinder containing toxic hydridic or flammable compounds is provided. The apparatus contains a cylinder for holding a pressurized fluid in an at least partial gas phase; a cylinder port body threaded to the upper part of the cylinder in a sealed position; a dual port head valve assembly disposed within the cylinder port body, wherein a first port is utilized to fill the cylinder with a pressurized fluid, and a second port in fluid communication with an outlet of the cylinder to discharge the pressurized fluid; a gas flow discharge path defined in part by the second port body and the outlet, and further including a restricted flow path and a flow channel disposed upstream of the second port body, but wherein the gas flow discharge path does not include a restrictive element selected from the group of pressure regulators, check valves and restrictive flow orifices; and the restricted flow path limits the flow rate of the gas discharged from the cylinder to 5,000 sccm when the outlet of the cylinder is exposed to an atmospheric condition.
Abstract:
A method and apparatus for plating a threaded portion of a high pressure gas cylinder is provided. The method includes: providing a high pressure gas cylinder having a gas containing portion and a threaded portion being formed on a top of the gas containing portion; locating an anode pipe, in which a plating solution passage is formed, inside the threaded portion; forming a closed chamber containing the threaded portion and the anode pipe; forming a flux of the plating solution inside the closed chamber; and forming a voltage difference between the anode pipe and the threaded portion, and plating the threaded portion.
Abstract:
An apparatus for providing a pressurized gas inline valve assembly incorporating a check valve to maintain pressure above a selectable psi and a ball valve for selectively shutting off gas flow. The apparatus is preferably positioned approximate the gas source in a beverage dispensing system that uses carbon dioxide for carbonation, preservative and propellant. Preferably, the apparatus is designed to maintain the system pressure above the threshold pressure that when below said threshold pressure the carbon dioxide would revert to its inoperative dry ice solid state as opposed to its operative liquid state.
Abstract:
A method of coating an interior of a gas storage container, where the method includes supplying a chemical vapor precursor to the storage container, and forming a metal coating on the interior surface of the container, where the coating is formed from the chemical vapor precursor. Also, a gas storage container that includes a gas storage vessel with an interior surface that has a liner formed on the interior surface of the storage vessel. The liner may include tungsten metal with a purity of about 99%, by weight, or more. Additionally, a system for making a metal lined gas storage container that may include a chemical vapor precursor generator, and a precursor injection assembly for transporting the precursor into a gas storage vessel. The system may also include an exhaust outlet for removing gaseous deposition products from the gas storage vessel.
Abstract:
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container (10) and an inner container (20) situated within the outer container (10). In the outer container (10) a chamber (11) for material (12) to be dispensed is arranged and in the inner container (20) a propellant chamber (21) for propellant (20) is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container (10) is closed by a cover part (15) on which a valve part (16) is arranged for dispensing the material (12) from the chamber (11) outwards. To improve pressurized packages of this type, a pressurized cartridge (30) containing a propellant (22) is arranged in the inner container (20), and the pressurized cartridge is associated with an opening mechanism (31) for at least one-time opening of the pressurized cartridge (30) to the propellant chamber (21) of the inner container (20). The opening mechanism (31) reacts to filling of the chamber (11) with material (12) to be dispensed.
Abstract:
A method of filling and sealing a gas capsule having (i) a hollow body portion and (ii) an elongate hollow neck portion having a free open distal end extending from the body portion is disclosed. The method is accomplished by applying a filling cap to the open end of the neck portion while evacuating the capsule and refilling with helium. Two crimping steps while pressure is maintained finishes the filling and sealing method.
Abstract:
A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.
Abstract:
A liquefiable gas pressure cylinder and method for making the same with the cylinder including a cylindrical shell, and heads fusion welded at opposites ends of the shell. The side ends where the heads are joined to the shell are crimped radially inward to each end to form chimes. The welds are 100% radiographed and heat treated. The heads are dished to have a domed center portion which has a profile and thickness so that the domed center portions will reverse before any other part of the cylinder is stressed beyond a yield limit for such part.
