Title: Innovations by Pui Yuen Ng
Introduction
Pui Yuen Ng is an accomplished inventor based in Eastvale, CA. She has made significant contributions to the field of engineering, particularly in the design of check valves. With a total of 3 patents to her name, her work showcases her innovative spirit and technical expertise.
Latest Patents
One of her latest patents is a spring stop for a clapper valve. This invention includes a check seat that defines a flow path and a clapper assembly designed to obstruct this flow path. The clapper assembly features a clapper and a seal retainer that is detachably mounted to the clapper. Additionally, a cam arm connected to the check seat includes a stopper, and a torsion spring applies a biasing force to the cam arm against the direction of fluid flow. This design ensures that when the seal retainer is dismounted from the clapper, the stopper contacts the check seat to prevent rotation of the cam arm.
Another notable patent is a clapper with an upstream cam-arm and roller arrangement. This check valve design also includes a check seat defining a flow path and a clapper assembly that obstructs this path. The assembly features a first extension with a roller and a cam arm that is rotatable relative to the clapper assembly. The torsion spring applies a biasing force to the cam arm in the upstream direction, allowing the clapper assembly to effectively obstruct the flow path.
