Patent number: 11959557Abstract: An evacuation unit is configured to remove entrapped fluid from a flow control. These configurations may incorporate devices that can passively discharge fluid in response to loss of system pressure. These devices may use gravity or spring-assist as mechanisms to move fluid out of spaces in the device. This feature mitigates risks that the entrapped fluid freezes and expands, which can cause damage to metal components and lead to extensive downtime of process lines. As an added benefit, the features can reduce product costs or complexity because the proposed designs avoid the need for additional, peripheral “accessories,” like pumps or heating elements, resident at the location of the flow control.Type: GrantFiled: August 31, 2022Date of Patent: April 16, 2024Assignee: Dresser, LLCInventors: Rajesh Krithivasan, Richard John Klimas, Jr., Jason Glen Knudson
