Extended orifice plug for a fluid system
An assembly is provided for a fluid system. This fluid system assembly includes a fluid conduit and a plug. The fluid conduit has an internal bore. The internal bore is configured as or otherwise includes a smooth-walled internal bore. The plug includes a protrusion and a head. The protrusion is connected to the head. The protrusion projects axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug. The head is seated against the fluid conduit. The head seals an opening in the fluid conduit to the internal bore.
1. An assembly for a fluid system, comprising:
a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and
a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;
wherein at least a portion of the protrusion is twisted about the axial centerline.
2. The assembly of claim 1 , wherein at least a portion of the protrusion has a polygonal cross-sectional geometry.
3. The assembly of claim 1 , wherein the head comprises a wrenching feature.
4. The assembly of claim 3 , further comprising:
a nut securing the plug to the fluid conduit;
the head projecting axially through an aperture in the nut towards the wrenching feature.
5. The assembly of claim 1 , wherein the head is seated against the fluid conduit at a cone seal interface.
6. The assembly of claim 1 , further comprising a nut securing the plug to the fluid conduit.
7. The assembly of claim 6 , wherein
the nut includes a sleeve and an inner rim;
the sleeve is mated with the fluid conduit at a threaded interface; and
the head is sandwiched axially between the inner rim and an end of the fluid conduit.
8. An assembly for a fluid system, comprising:
a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and
a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;
wherein the plug further includes a flexible wire bristle pack arranged within the internal bore and attached to the protrusion.
9. The assembly of claim 8 , wherein the head comprises a wrenching feature.
10. The assembly of claim 9 , further comprising:
a nut securing the plug to the fluid conduit;
the head projecting axially through an aperture in the nut towards the wrenching feature.
11. The assembly of claim 8 , wherein the head is seated against the fluid conduit at a cone seal interface.
12. The assembly of claim 8 , further comprising a nut securing the plug to the fluid conduit.
13. The assembly of claim 12 , wherein
the nut includes a sleeve and an inner rim;
the sleeve is mated with the fluid conduit at a threaded interface; and
the head is sandwiched axially between the inner rim and an end of the fluid conduit.
14. An assembly for a fluid system, comprising:
a fluid conduit with an internal bore, the internal bore comprising a smooth-walled internal bore; and
a plug including a protrusion and a head, the protrusion connected to the head and projecting axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug, and the head seated against the fluid conduit and sealing an opening in the fluid conduit to the internal bore;
wherein at least a portion of the axial centerline is non-straight and the protrusion comprises flexible material.
