Abstract
A poppet coupling comprising a male member comprising a cylindrical body part comprising a first outer diameter, and a cylindrical nose part having a second outer diameter, at an end which is to be inserted into a female member first; and the female member comprising an end opening for receiving the male member first, a primary seal for engaging the cylindrical body part, a cone-shaped opening, and a cylindrical opening, the cylindrical opening having a first inner diameter for receiving the cylindrical nose part.
Claims20
A poppet coupling comprising:
- a male member including a cylindrical body part and a cylindrical nose part, the cylindrical body part having a first outer diameter, the cylindrical nose part having a second outer diameter, the cylindrical nose part disposed at an end of the male member;
- and
- a female member including an end opening, a primary metal seal, a cone-shaped opening, and a cylindrical opening, the end opening configured for receiving the end of the male member, the primary metal seal for engaging the cylindrical body part, the cylindrical opening having a first inner diameter for receiving the cylindrical nose part, the cone-shaped opening opens outward from the cylindrical opening, the cone-shaped opening opens towards the end opening, the primary metal seal arranged between the end opening and the cone-shaped opening,
- wherein the second outer diameter and the first inner diameter are complementary to allow the cylindrical nose part to be slidably inserted into the cylindrical opening, wherein insertion of the cylindrical nose into the cylindrical opening respectively guides and aligns the male member and the female member, wherein the primary metal seal is configured to seal against an outside of the cylindrical body part with the first outer diameter of the male member, wherein at least a part of the cylindrical nose part is inside the cylindrical opening when the primary metal seal initially engages the outside of the cylindrical body part with the first outer diameter of the male member while the male member is inserted into the female member.

A poppet coupling system comprising:
- a plurality of poppet couplings arranged to form a multi-poppet coupling between a first subsea member and a second subsea member, each poppet coupling including:
- a male member including a cylindrical body part and a cylindrical nose part, the cylindrical body part having a first outer diameter, the cylindrical nose part having a second outer diameter, the cylindrical nose part disposed at an end of the male member, and
- a female member including an end opening, a primary metal seal, a cone-shaped opening, and a cylindrical opening, the end opening configured for receiving the end of the male member, the primary metal seal for engaging the cylindrical body part, the cylindrical opening having a first inner diameter for receiving the cylindrical nose part, the cone-shaped opening opens outward from the cylindrical opening, the cone-shaped opening opens towards the end opening, the primary metal seal arranged between the end opening and the cone-shaped opening,
- wherein the second outer diameter and the first inner diameter are complementary to allow the cylindrical nose part to be slidably inserted into the cylindrical opening, wherein insertion of the cylindrical nose into the cylindrical opening respectively guides and aligns the male member and the female member, wherein the primary metal seal is configured to seal against an outside of the cylindrical body part with the first outer diameter of the male member, wherein at least a part of the cylindrical nose part is inside the cylindrical opening when the primary metal seal initially engages the outside of the cylindrical body part with the first outer diameter of the male member while the male member is inserted into the female member.
