摘要 |
<p>A high pressure valve for oxygen service comprises a valve body ( 10 ) with a gas passage ( 12 ) and a valve seat ( 18 ) associated with the gas passage ( 12 ). An obturation unit ( 22 ) is movable between a first position, wherein it is spaced from the valve seat ( 18 ), and a second position, wherein it is seated on the valve seat ( 18 ). This obturation unit ( 22 ) has a sealing surface ( 24 ) that is in sealing contact with the seat surface ( 20 ) in said second position of the obturation unit ( 22 ). A metallic sealing element ( 32 ) and a synthetic sealing element ( 34 ) co-operate to form the sealing surface ( 24 ). The metallic sealing element ( 32 ) forms the sealing surface ( 24 ) around said inner border of the seat surface ( 20 ), and the synthetic sealing element ( 34 ) forms the sealing surface ( 24 ) towards the outer border of the seat surface ( 20 ).</p> |
