摘要： A pressure relief valve to balance the pressure between a cargo tank and the ambient atmosphere is described. The valve is so arranged that the velocity of the out flowing gas jet at no time is under a preset value when the valve is in open position. The valve comprises a valve body (2) designed to act against a valve seat (1) located in a structural outlet (5a) from the cargo tank, which valve body (2) is connected to a rod (7) extending into the structural outlet (5a) opening (5). The rod (7) is being supported and guided by a frame structure (6) extending into the structural outlet (5a) opening (5) and fixed to the structural outlet (5a).

摘要： A pressure relief valve for pressure equalization between an essentially closed space and the surrounding atmosphere is disclosed. The pressure relief valve includes a valve housing with: a cylindrical wall defining a flow passage, a valve body arranged to cooperate with a valve seat arranged in the outflow of the valve housing, a stem configured for axial guidance of the valve body, a lifting element or plate arranged further down in the flow passage relative to the valve seat, a flow constriction defining an essentially truncated conically shaped interior and arranged to encircle the lifting element such that a radial passage between the lifting element and flow constriction increase when the lifting element and the valve body is moved from a closed state of the pressure relief valve towards an open state of the pressure relief valve.

摘要： The present disclosure provides for an above-ground mobile storage tank that can be used in a variety of different commercial applications. In one embodiment, the storage tank may comprise a tank shell, wherein the tank shell further comprises at least one floor wall, at least one top wall, and at least four side walls. The side walls may each be affixed to the floor wall and the top wall to from an interior tank space. Each of the wall panels may comprise a copolymer polypropylene material. The storage tank may also comprise a plurality of steel reinforcements, wherein each reinforcement is configured to encapsulate the tank shell. Each reinforcement may be affixed to a trailer, which is configured to transport the tank shell. The storage tank may also comprise a plurality of slip plates located on the trailer to enable the tank shell to “float” above the trailer.
