Latest Patents

One of Xiaofeng Li's notable inventions is a check valve designed for low pressure operating conditions. This check valve comprises a valve cover, a valve body, and an upper diaphragm positioned between the body and the cover. It features a first pressure cavity on the lower surface of the valve cover, which accommodates a backward direction medium. Additionally, a second pressure cavity is machined on the upper surface of the valve body, containing both an inflow passage and an outflow passage. The inflow hole allows the medium to enter the second pressure cavity, applying upward pressure on the upper diaphragm. Furthermore, a backflow channel is integrated into the outflow passage, enhancing the valve's functionality.

Another significant patent involves a heat transfer enhancement pipe, which is crucial in the field of fluid heat transfer. This invention includes a tubular pipe body with an inlet for fluid entry and an outlet for fluid exit. The internal wall of the pipe body is equipped with a fin that protrudes inward, featuring one or more fin sections that extend spirally along the axial direction of the pipe. This design reduces thermal stress, thereby increasing the service life of the heat transfer enhancement pipe.
