Three-way Integrated Joule-Thomson Valve and Liquefied Gas Expander

摘要

A cryogenic turbine expander system which consists essentially of a cryogenic liquid pressure vessel, and the vessel further accommodating a turbine expander, an internal bypass configuration, which are operable in parallel, a three-way valve to direct incoming high pressure liquefied gas flow to the turbine expander, or the internal bypass configuration, which further consists a Joule-Thomson valve, when the turbine expander is not operational.

1. A flat three-way valve in a flat design for use in a cryogenic liquefied gas expansion system, the three-way valve further comprising:
one inlet portion and two outlet portions; and three horizontal flat disc portions rotating at a common center and a plurality of through holes on each disc portion's rim, the middle flat disc portion driven by an external motor and rotated such that the through holes of the three flat disc portions open and close passages between the inlet and the two outlet portions.
