Housing with intersecting passages for high pressure fluid applications

摘要

A housing for use in high pressure fluid applications comprises a first drilling having a region of enlarged diameter bounded by an upper boundary in a first plane and a lower boundary in a second plane; and a second drilling intersecting with the first drilling via an intersection region. The intersection region includes a first substantially flat surface which defines a ceiling of the intersection region and which intersects the upper boundary of the region of enlarged diameter, and a second substantially flat surface which is opposed to the first substantially flat surface and which defines a floor of the intersection region and intersects the lower boundary of the region of enlarged diameter. As the flat surfaces are in alignment with a region of maximum hoop stress they do not act as a significant stress raiser at the intersection.

1. A housing (30) for use in high pressure fluid applications, the housing comprising:
a first drilling (32a, 32b), defining a first axis, and having a region of enlarged diameter (32b) bounded by an upper boundary (36) in a first plane and a lower boundary (38) in a second plane; and a second drilling (42), defining a second axis, and intersecting with the first drilling (32a, 32b) via an intersection region (44); wherein the intersection region (44) includes, a first substantially flat surface (54) which defines a ceiling of the intersection region (44) and which intersects the upper boundary (36) with no blend radius, and a second substantially flat surface (56) which is opposed to the first substantially flat surface (56) and which defines a floor of the intersection region (44) and intersects the lower boundary (38) with no blend radius, wherein the first and second substantially flat surfaces (54, 56) are substantially perpendicular to the first axis so as to align with the plane of a respective one of the upper and lower boundaries (36, 38), wherein the first and second axes intersect with one another.
