Avluftingsenhet for trykkavlasting av et trykksatt brönnverktöy |
摘要 |
<p>A bleed valve design for a wireline pressure setting tool is disclosed. The chamber within the setting tool is vented through a bleed valve assembly which features a rupture disk secured over an opening with an O-ring seal. A piercing tool is used and in conjunction with the shape of the rupture disk creates a break in the rupture disk in a manner that will not reseal. Lateral passages are provided to direct the vented gases away from operating personnel. An alternative venting mechanism is provided by having a thin wall segment which can be penetrated by a piercing tool in the event the rupture disk assembly for any reason fails to allow venting of the setting tool.</p> |
