Relief valve assembly with anti-frozen shielding hat |
摘要 |
A relief valve assembly includes a relief valve, a hollow shell disposed on the relief valve so as to form a relieving chamber, and a cap mounted to the hollow shell and closing off a distal end of the relief valve to an external environment. The hollow shell has a distal aperture and a proximal aperture, and the distal end of the relief valve is inserted into the hollow shell through the proximal aperture and protrudes through the distal aperture. The relief valve includes a relief port forming a fluid flow path between a valve chamber of the relief valve and the relieving chamber, and the hollow shell extends past the relief port along a longitudinal axis of the relief valve. The relief valve includes a slide member configured to move in response to an over-pressure condition, and a fluid vents from the valve chamber to the relieving chamber through the relief port. |

1. A relief valve assembly, comprising:
a relief valve including a valve body having a valve chamber and a slide member configured to move inside the valve chamber; a hollow shell disposed to an outer surface of the valve body in order to form a relieving chamber between the relief valve and the hollow shell, wherein the hollow shell has a distal aperture and a proximal aperture, and a distal end of the valve body is inserted into the hollow shell through the proximal aperture and protrudes through the distal aperture; and a cap mounted to the hollow shell and configured to close off the distal end of the valve body to an external environment; wherein the relief valve includes at least one relief port forming a fluid flow path between the valve chamber and the relieving chamber, the hollow shell extends past the at least one relief port along a longitudinal axis of the valve body, and the slide member moves in response to an over-pressure condition, thereby allowing a fluid to vent from the valve chamber to the relieving chamber through the at least one relief port; wherein the hollow shell includes a wide portion, a narrow portion, and a connecting portion connecting the wide portion and the narrow portion; and wherein the connecting portion includes a ring-shaped depression with a ring-shaped sealing member disposed therein. |
