High-pressure container opening nozzle structure suitable for rapid opening and closing

Abstract

The invention discloses a high-pressure container opening nozzle structure suitable for rapid opening and closing. The high-pressure container opening nozzle structure comprises a nozzle, a cover plate, a link mechanism and tensioning mechanisms. The nozzle is arranged in a shell opening of a high-pressure container, the inner end face of the nozzle makes contact with the outer surface of the cover plate in a sealed mode, and two U-shaped plates and a handle are fixed to the middle of the outer surface of the cover plate in parallel. The outer sides of the two U-shaped plates are respectively provided with a guiding plate. The centers of the guiding plates and the centers of the U-shaped plates are connected through screws in a rotating mode. The inner surface of the cover plate is connected with the inner wall of a shell through the link mechanism which is movably hinged. The two U-shaped plates on the outer surface of the cover plate press against the outer end face of the nozzle through the two tensioning mechanisms, so that the cover is tightly connected with the nozzle. The high-pressure container opening nozzle structure is easy to assemble and disassemble and high in opening and closing efficiency, self-tensioning sealing can be achieved when internal pressure is high, the position of the cover plate can be controlled freely by the handle, the cover plate can be controlled to be opened and closed freely, and operation is convenient.

Description

technical field [0001] The invention relates to a high-pressure container opening connection structure, in particular to a high-pressure container opening connection structure suitable for rapid opening and closing. Background technique [0002] In the production process of petroleum, pharmaceutical and traditional chemical industries, frequent opening and closing of open pipes is often involved. On the one hand, due to the special requirements of the process, it is necessary to perform intermittent feeding and discharging operations on the equipment, such as the operation of large-scale mixing equipment; on the other hand, when the container has complex internal components or the material is highly corrosive, it is necessary to set up Manholes or hand holes, regular maintenance of equipment. [0003] The traditional connecting pipe, port and hand hole cover are connected by bolt flange. The bolt flange structure is relatively mature, and the corresponding standard parts ca...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the defects of low opening and closing efficiency and poor sealing effect of the bolted flange connection under the high-pressure working condition of rapid opening and closing, the purpose of the present invention is to provide a high-pressure vessel opening and connecting structure suitable for rapid opening and closing, which has a high Excellent opening and closing efficiency, good sealing effect, and self-tightening sealing characteristics under high pressure
