Sealing device

Abstract

The present invention relates to a sealing device comprising a sealing ( 1 ) which is threaded onto a sleeve ( 7 ), where the sleeve ( 7 ) is located in a base tube ( 11 ) comprising valve ports ( 12 ), and where the sealing device shall seal between the sleeve ( 7 ) and the base tube ( 11 ). The invention is characterized in that the sealing ( 1 ) is held in place by support rings ( 2 ), where the support rings is held in place by locking rings ( 3 ), where the lockings rings ( 3 ) fit into an inner suitable locking groove ( 6 ) in the sleeve ( 7 ), where the sleeve ( 7 ) comprises a threaded portion ( 8 ), where a locking nut ( 5 ) comprising an outer suitable locking groove ( 6 ) is arranged to be screwed over the sleeves ( 7 ) threaded portion ( 8 ) and to be tightened sufficiently to hold the locking rings ( 3 ), support rings ( 2 ) and sealing ( 1 ) in place outside the sleeve ( 7 ).
