Abstract
A pressure relief valve is provided. The pressure relief valve includes a hollow body having an inlet and an outlet, with the hollow body including at least one aperture extending through a surface of the hollow body. An actuator assembly is attached to the hollow body and a sleeve is slideably positioned about the hollow body, with the sleeve moveably attached to the actuator assembly. During operation, the actuator assembly moves the sleeve from a first position that covers the aperture to a second position that un-covers at least a portion of the aperture.
Claims15
A valve apparatus, comprising:
- a hollow body having an inlet and an outlet, the hollow body including at least one aperture extending through a surface of the hollow body;
- an actuator assembly coupled to the hollow body;
- and
- a sleeve slideably positioned about the hollow body, and moveably coupled to the actuator assembly;
- where the actuator assembly is structured to move the sleeve from a first position that covers the at least one aperture to a second position that un-covers at least a portion of the aperture.
A valve apparatus, comprising:
- a hollow body having an inlet and an outlet, the hollow body including at least one aperture extending through a surface of the hollow body;
- an actuator assembly coupled to the hollow body;
- a sleeve slideably positioned about the hollow body, and moveably coupled to the actuator assembly;
- a first pivot plate rotatably coupled to the hollow body at a first pivot point, the pivot plate including a slot that is sized to receive a pivot pin that extends from the sleeve;
- a second pivot plate rotatably coupled to the hollow body at a second pivot point located opposite the first pivot point;
- and
- a first strut coupled to both the first and second pivot plates;
- where the actuator assembly includes a rod that is coupled to the first strut, so that the actuator assembly can move the sleeve from a first position that covers the at least one aperture to a second position that un-covers at least a portion of the aperture.
A method of changing a pressure in a pressurized system, the method comprising the steps of:
- providing a hollow body having an inlet and an outlet, the hollow body including at least one aperture extending through a surface of the hollow body;
- providing an actuator assembly coupled to the hollow body;
- providing a sleeve slideably positioned about the hollow body, and moveably coupled to the actuator assembly;
- and
- moving the sleeve from a first position that covers the at least one aperture to a second position that un-covers at least a portion of the aperture, thereby changing a pressure in the pressurized system.
