Abstract

The invention relates to a tight connecting device. The tight connecting device comprises a first port piece, a second port piece, a sleeve, an elastic spacing piece, a first sealing element, a second sealing element, a first locking piece and a second locking piece; the sleeve is axially sleeved out of the elastic spacing piece, the first flange and the second flange; the first locking piece is fixedly connected with the sleeve; the first sealing element is axially pressed between a second surface of the first flange of the first port piece and the first locking piece, and butts against the inner ring surface of the sleeve; the second locking piece is fixedly connected with the sleeve; the second sealing element is axially pressed between a fourth surface of the second flange of the second port piece and the second locking piece, and butts against the inner ring surface of the sleeve; and the first port piece and the second port piece are tightly isolated from the external through the sealing elements. The tight connecting device is particularly suitable for the field of tight connection between high-pressure and high-temperature medium and variable-temperature and variable-pressure medium pipes and containers, such as spaceflight and deep sea fields.

Description

technical field [0001] The invention relates to the field of sealing, in particular to a sealing connection device used for connecting high temperature and high pressure, variable temperature and variable pressure fluid medium pipelines and equipment. Background technique [0002] Pipelines and storage containers for fluid media such as gas or liquid often need to be connected tightly by connectors. The detachable flange sealing connection is widely used in the sealing connection of pipelines and containers in the fields of chemical industry, energy and machinery because of its simple structure and easy operation. The traditional flange connection method uses fastening bolts to connect the two ports that need to be connected with flanges. A sealing element is placed on the sealing surface of the flange port. When the fastening bolt connects the two end faces together, it also presses the sealing element tightly on the sealing surface along the axial direction of the flange...
