Abstract

En indre utblåsningssikring omfatter en kuleventil med en rørformet enhet som har en midtre kanal, med et øvre og nedre sete montert i denne. En kule er roterbart anordnet mellom det øvre og nedre setet og omfatter en ytre overflate og en midtre åpning, idet den midtre åpningen omfatter en underskjæring. Et beskyttende belegg er påført på både den ytre overflaten og underskjæringen i kulen.
