Title: David James Alexander: Innovator in Valve Technology
Introduction
David James Alexander is a notable inventor based in Banchory, GB. He has made significant contributions to the field of valve technology, holding a total of 3 patents. His innovative designs focus on enhancing the functionality and efficiency of gate valves.
Latest Patents
One of his latest patents is the Split Seat Shear Valve. This invention features a gate valve seat designed to seal a valve body to a gate. The valve seat extends from a flow passage into a cavity of the valve body, which is parallel to the flow passage's axis. The cavity is perpendicular to the flow passage, allowing the gate to be positioned within it. The valve seat includes a tubular body with a face for contact with the gate and an end that is adjacent to the valve body. Additionally, it incorporates a sleeve on the inner diameter of the tubular body, which is designed to receive shear force for shearing a member extending through the flow passage, with an adjustable inner sleeve length.
Another significant invention is the Rotational Shear Valve. This rotating gate valve is capable of shearing cables or tubing as it closes to obstruct flow. The valve body features a flow passage and a lateral bore that is transverse to the flow passage. The gate has a cylindrical shape and rotates about its axis while moving laterally to close the flow passage. This innovative design allows for the shearing of articles such as cables and tubing that extend through the flow passage.
