Title:
TWO-WAY VALVE FOR FLOW RATE CONTROL AND TEMPERATURE CONTROL DEVICE IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2018/096712
Kind Code:
A1
Abstract:
Provided are: a two-way valve for flow rate control that is capable of controlling the flow rate of a fluid in a linear fashion with better precision than a switching valve in which a communication hole that opens a flow path in conformity with an outflow part is simply opened in a valve body; and a temperature control device in which this two-way valve is used. This two-way valve for flow rate control is provided with: a valve main body (6) which has a valve seat (8) comprising a columnar empty space, and in which a first valve port (9) through which fluid a flows is formed in one axial-direction end of the valve seat (8) and a rectangular-cross-sectioned second valve port (11) through which the fluid flows is formed in the peripheral surface of the valve seat (8); a valve body (12) rotatably disposed inside the valve seat (8) of the valve main body (6) and formed in a shape that creates a cylindrical part having a predetermined central angle α so as to linearly change the opening area of the second valve port (11); and a drive means (3) that rotatably drives the valve body (12).
