Abstract
A safety head is disclosed. More particularly, a safety head comprising a circular flange portion and at least one protrusion is disclosed, wherein the at least one protrusion has a face exhibiting a blended radius of curvature. The circular flange portion may be thicker than the at least one protrusion. A safety head assembly is also disclosed, wherein the safety head assembly comprises an inlet safety head and an outlet safety head. Additionally, a safety head assembly is disclosed wherein the inlet safety head comprises a peripheral protrusion, the outlet safety head comprises a peripheral protrusion, and a clamp ring is configured to engage with the peripheral protrusions.
Claims28
A safety head, comprising:
- a circular flange portion having an inner bore defining a fluid flow path, the circular flange portion having an upper flat flange surface and a lower flat flange surface,
- at least one protrusion extending outwardly from the circular flange portion and defining at least one bolt hole, wherein the at least one protrusion has a face exhibiting a blended radius of curvature, wherein the at least one protrusion is a wave, and wherein the at least one protrusion has an upper protrusion surface and a lower protrusion surface;
- wherein the distance between the upper flat flange surface and lower flat flange surface defines a first thickness;
- wherein the distance between the upper protrusion surface and the lower protrusion surface defines a second thickness;
- and
- wherein the second thickness is less than the first thickness.

A safety head assembly, comprising:
- an inlet safety head comprising:
- a circular flange portion having an inner bore defining a fluid flow path, the circular flange portion having an upper flat flange surface and a lower flat flange surface,
- at least one protrusion extending outwardly from the circular flange portion and defining at least one bolt hole, wherein the at least one protrusion has a face exhibiting a blended radius of curvature, wherein the at least one protrusion is a wave, and wherein the at least one protrusion has an upper protrusion surface and a lower protrusion surface;
- wherein the circular flange portion is thicker than the at least one protrusion;
- an outlet safety head comprising:
- a circular flange portion having an inner bore defining a fluid flow path, the circular flange portion having an upper flat flange surface and a lower flat flange surface,
- at least one protrusion extending outwardly from the circular flange portion and defining at least one bolt hole, wherein the at least one protrusion has a face exhibiting a blended radius of curvature, wherein the at least one protrusion is a wave, and wherein the at least one protrusion has an upper protrusion surface and a lower protrusion surface;
- wherein the circular flange portion is thicker than the at least one protrusion;
- and
- at least one bolt having a head and a threaded portion, the at least one bolt extending between the at least one bolt hole of the inlet safety head and the at least one bolt hole of the outlet safety head to join the inlet safety head to the outlet safety head;
- wherein
- the head projects above the at least one protrusion of the outlet safety head;
- and
- at least a portion of the threaded portion is exposed between the at least one protrusion of the inlet safety head and the at least one protrusion of the outlet safety head.
11 more elements
A safety head assembly, comprising:
- an inlet safety head comprising:
- a body having an inner bore defining a fluid flow path, the body also having a flange portion;
- and
- at least one inlet safety head projection projecting outwardly from the body of the inlet safety head, the at least one inlet safety head projection having a face exhibiting a blended radius of curvature, wherein the at least one inlet safety head projection is a wave;
- an outlet safety head comprising:
- a body having an inner bore defining a fluid flow path, the body also having a flange portion;
- and
- at least one outlet safety head projection projecting outwardly from the body of the outlet safety head, the at least one outlet safety head projection having a face exhibiting a blended radius of curvature, wherein the at least one outlet safety head projection is a wave;
- wherein the flange portion of the inlet safety head and the flange portion of the outlet safety head are configured to receive an insert device placed between them.
