CONNECTION STRUCTURE FOR HOLDING LEAKPROOF IN A HIGH TEMPERATURE AND HIGH PRESSURE CONDITION BY USING CONNECTORS AND A COVER

摘要

PURPOSE: A connection structure for holding leakproof in a high temperature and high pressure condition is provided to secure primary airtight effect by equalizing a contact area between a head unit and an insertion groove and to obtain secondary airtight effect by an airtight block. CONSTITUTION: A connection structure(10) for holding leakproof in a high temperature and high pressure condition is composed of a first connector(11) having a hemispheric head unit(11a); a second connector(13) having an equilateral trapezoid insertion groove(13a) into which the head unit is fitted to hold a uniform contact area; and a cover(12) joined to a combining portion between the connectors to fix and protect the combining portion. A stopper(11b) is protruded at the outer periphery under the head unit. A hanging protrusion(12a) is projected at the inner periphery of the cover to correspond to the stop protrusion.
