Title:
FLOW CONTROL THREE-WAY VALVE AND TEMPERATURE CONTROL DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/037589
Kind Code:
A1
Abstract:
Provided are: a flow control three-way valve capable of controlling the mixing ratio of two kinds of fluids more precisely than three-way valves provided with an inflow port into which a high temperature circulating heat medium liquid flows, an inflow port into which a low temperature circulating heat medium liquid flows, an outflow port out of which a constant temperature circulating heat medium liquid flows, and a control valve for controlling the flow ratio between the high temperature circulating heat medium liquid and the low temperature circulating heat medium liquid; and a temperature control device using same. The flow control three-way valve is provided with: a valve body in which are formed a first valve port with a rectangular cross-section into which a first fluid flows and a second valve port with a rectangular cross-section into which a second fluid flows, and which has a valve seat that is configured from a cylindrical space; a valve element, which is disposed to rotate freely in the valve seat of the valve body so as to switch the first valve port from a closed state to an open state while simultaneously switching the second valve port from an open state to a closed state, which is formed in a semicircular cylinder shape with a previously determined central angle, and in which the two end surfaces in the circumferential direction are formed as curved surfaces; and a driving means for rotating the valve element.
