Abstract
An adaptor assembly includes: an adaptor piece including: a forged outer wall defining a substantially cylindrical shape; a through hole disposed at a top portion of the adaptor piece, the through hole defining an adaptor center cavity; a threaded portion disposed beneath the through hole; and a second hole disposed beneath the threaded portion. The adaptor assembly includes a hex socket including external threading. A diameter of the through hole is smaller than a diameter of the second hole. The hex socket is inserted through the second hole and screwed into the adaptor piece such that the external threading mates with the threaded portion.
Claims20
An adaptor assembly comprising:
- an adaptor, comprising:
- an outer wall;
- a first hole disposed in the outer wall;
- a threaded portion disposed in the outer wall;
- and
- a second hole disposed in the outer wall, wherein the threaded portion is disposed axially between the first and second holes;
- and
- a socket comprising external threading, a tool recess disposed within a first end, and a through bore disposed within a second end opposite from the first end, wherein a first diameter of the through bore is smaller than a second diameter of the second hole, the socket is inserted through the second hole and screwed into the adaptor such that the external threading mates with the threaded portion, and the through bore extends into the tool recess.
A system, comprising:
- an orifice assembly comprising:
- a first portion comprising a first passage;
- an adaptor portion comprising a second passage and internal threads;
- a socket comprising external threads, an orifice, and a tool recess, wherein the socket is disposed in the adaptor portion along the second passage, such that the external threads of the socket are threadingly coupled to the internal threads of the adaptor portion;
- and
- an access portion comprising a third passage, wherein the second and third passages are coaxial with one another, the first passage is crosswise relative to the second and third passages, the first passage intersects the second and third passages axially between the adaptor portion and the access portion, the tool recess of the socket faces toward the access portion, and the tool recess is configured to receive a tool through the access portion to rotate the socket.
A heat recovery steam generator (HRSG) comprising:
- at least one orifice assembly, the at least one orifice assembly comprising:
- an adaptor portion, the adaptor portion configured to receive at least one fluid, the adaptor portion further comprising:
- a through hole comprising a threaded portion;
- and
- a hex socket comprising external threading, the hex socket further comprising:
- a hexagonal recess disposed within a first end of the hex socket;
- and
- a through bore disposed within a second end of the hex socket, the second end at an opposite end of the hex socket from the first end, wherein the through bore extends into the hexagonal recess.
