Valve sealing arrangement for controlling fluid flow
The patent US12072042B2 presents a novel valve sealing arrangement designed to enhance flow control within a valve body. Central to this arrangement is a valve body featuring a flow passage, a control member that regulates flow, and a rotary shaft that operates the control member between open and closed positions. The valve seat is a critical component, comprising an anchor portion secured to the valve body, which includes a sealing surface that prevents leakage. This anchor portion features a convolution section with at least one bend, allowing for resilient movement of a first seat portion that contacts the control member to create a secondary seal. The design also incorporates a second seat portion that extends axially and contacts the side wall of the flow passage, ensuring a comprehensive sealing mechanism.
Further claims detail the structural and functional aspects of the valve seat, including the absence of a radial sealing element between the second seat portion and the side wall, which facilitates controlled leakage flow. The arrangement allows for the first seat portion to be biased radially inward, enhancing sealing effectiveness. The patent also describes the potential for the valve seat to be formed from various materials, including metallic alloys, and the possibility of utilizing additive manufacturing processes for production. The design's flexibility is underscored by the ability of the convolution section to compress and allow movement of the first seat portion, thereby optimizing the sealing performance under varying operational forces. Overall, this patent outlines a sophisticated valve sealing arrangement that promises improved reliability and efficiency in fluid control applications.
