Title: Baohai Liu – Innovator in Liquid Sealing Technologies

Introduction

Baohai Liu, an accomplished inventor based in Carol Stream, IL, has made significant contributions to the field of liquid sealing technologies. With two patents to his name, Liu has focused on developing innovative solutions aimed at minimizing hazardous emissions and enhancing the functionality of pressure and vacuum venting systems.

Latest Patents

Liu's latest patents include a "Gauge Hatch with Liquid Seal" and a "Vent Valve with Liquid Seal." The gauge hatch features a unique cover structure that integrates a pallet and diaphragm combination, working alongside a pressure-responsive liquid seal subassembly. This design includes a vent neck and a circumferentially extending reservoir, which prevents low-level fugitive vapor emissions when the appropriate vent neck pressure is not exceeded. The liquid seal mechanism is designed to open under specific conditions to ensure efficient functionality.

His second patent, the "Vent Valve with Liquid Seal," also leverages a pallet/diaphragm type valve combined with a pressure-responsive liquid seal. This invention addresses the need to inhibit low-level fugitive emissions from tanks associated with the vent valve. The sealed chamber retains emissions until sufficient pressure is attained to displace the sealing liquid, providing reliable performance as a pressure vent, vacuum vent, or a combination of both.
