Title:
CONNECTABLE CHAMBER FOR PORTHOLE TESTING
Document Type and Number:
WIPO Patent Application WO/2005/047099
Kind Code:
A2
Abstract:
The invention relates to shipbuilding and can be used for strength and leakage tests of the portholes of low-volume submersible vehicles. A connectable chamber is used for increased external pressure testing of the submersible vehicle portholes (1) which are arranged in a cylindrical body (socket welded connection) (2) provided with a supporting flange (11). The body of a chamber (4) is embodied at least partially in the form of a spherical surface and comprises a joining flange (9) which is provided with an internal annular collar (10) embodied in such a way that it encompasses the porthole (1). A device (14) for pressing the body (4) against the socket welded connection (2) is embodied in the form of a banding ring (15) provided with a sectional annular insert (16) arranged thereinside the contact surfaces of the ring and insert being embodied in the form of the surface a truncated cone. The annular insert (16) is provided with an annular slot for simultaneously embracing the supporting (11) and joining (9) flanges. The ring (15) is tightened by bolts (17), whereby the perfect junction thereof to the annular insert (16) and the tight crimping of the spherical body of the chamber (4) through a sealing ring are maintained. A working medium is supplied inside the body (4) by an internal pressure source. The inventive device reduces the test duration, increases the reliability thereof and can be used directly during the submersible vehicle operation.
