US 2017/0204756 A1 · PASSIVE EXHAUST VALVE ASSEMBLY WITH OVERLAPPING SLIP JOINT AND METHOD OF FORMING AND INSTALLATION

Abstract

A passive exhaust valve assembly includes an exhaust conduit that has a first pipe section attached in generally axial alignment with a second pipe section. The end portion of the first pipe section includes a circumferential segment disposed within the end portion of the second pipe section to form an overlapping interface. The end portions of the first and second pipe sections each include a flange protruding radially outward from the respective first or second pipe section, whereby the flanges engage with each other to form an axle seat therebetween. A support shaft extends laterally across an interior volume of the exhaust conduit and rotatably engages the axle seat. A valve plate is coupled to the support shaft within the interior volume of the exhaust conduit for moving relative to the exhaust conduit between open and closed positions.

A method of assembling of a passive exhaust valve assembly, said method comprising:

providing a first pipe section and a second pipe section, wherein an end portion of first pipe section is sized to matably fit within an end portion of the second pipe section;
forming a flange that protrudes radially outward along a portion of the circumference of each end portion of the first and second pipe sections;
forming a first seat portion on the flange of the first pipe section;
forming a second seat portion on the flange of the second pipe section;
engaging a support shaft in one of the first and second seat portions, wherein the support shaft includes a valve plate attached to an intermediate portion of the support shaft;
inserting the first pipe section within the second pipe section to form an overlapping interface between the end portions of the first and second pipe sections;
engaging the first seat portion with the second seat portion to form an axel seat circumferentially around the support shaft, upon inserting the first pipe section within the second pip section;
and
welding the overlapping interface to attach the first pipe section to the second pipe section and form an exhaust conduit.
