Abstract
Embodiments of a door assembly with a door component that can open and close in response to pressure of fluids that flow in a fluid handling system. These embodiments utilize elements to seat and lock the door in position without the need for manual intervention and/or interaction, e.g., by a technician and/or maintenance personnel. However, these elements do not need to support the weight of the door and, thus, provide a more robust and cost effective design to achieve automated and reliable operation necessary for use in fluid handling systems.
Claims20
A door assembly, comprising:
- a door component with a pivot axis that permits the door component to move between a first position and a second position, the door component having a bottom portion with an engagement feature extending generally downwardly from the door component;
- and
- a reset component comprising a latch component that engages the engagement feature in the first position and a grabber element having at least one orientation that biases the door component toward the first position.
A closure assembly for a blow-in door on a fluid handling system,
- a plurality of actuators comprising a first actuator and a second actuator;
- a grabber element coupled to the first actuator, the grabber element having a first orientation and a second orientation that is radially offset from the first orientation relative to the blow-in door;
- a lever element coupled to the second actuator;
- and
- a latch element engaging the lever element,
- wherein the lever element moves in response to the second actuator to change the position of the latch element from a latched position that engages the blow-in door to an unlatched position that permits the blow-in door to move from a first position to a second position that is different from the first position.
A method of operating a closure assembly for a blow-in door, comprising
- receiving a first signal indicating a position of the blow-in door;
- generating a first output in response to the first signal that contains instructions to move a grabber element from a first orientation to a second orientation,
- wherein the second orientation biases the blow-in door toward a closed position.
