Title:
FLOW-PATH SWITCHING VALVE, AND POWER GENERATING SYSTEM AND UNINTERRUPTIBLE POWER SYSTEM EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2021/117564
Kind Code:
A1
Abstract:
Provided is a flow-path switching valve capable of switching a gas supply source without stopping the motion of a gas engine electricity generator. This valve is provided with a structural component having first and second flow passages, a main body part which includes first and second fluid input passages and one fluid output passage and which encloses the structural component in a hermetic state and in such a way as to be capable of rotating in a flow passage switching direction, and a switching unit which causes the structural component to rotate, wherein: the first flow passage joins the first fluid input passage to the fluid output passage; the second flow passage joins the second fluid input passage to the fluid output passage; and in conjunction with the rotation by the switching unit, the structural component causes an opening surface area generated by an overlap of the first fluid input passage and the first flow passage to decrease, and simultaneously causes an opening surface area generated by an overlap of the second fluid input passage and the second flow passage to increase, such that a uniform amount of fluid is discharged from the fluid output passage per unit time during flow passage switching. Employing a valve having this configuration enables the gas supply source to be switched without stopping the gas engine electricity generator.
