Title:
TWO-WAY VALVE FOR FLOW CONTROL AND TEMPERATURE CONTROLLER USING THE SAME
Document Type and Number:
Japanese Patent JP2018084259
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a two-way valve for flow control capable of controlling a flow rate of fluid linearly with accuracy, compared to a selector valve in which a communication hole configured to match with an outflow part and open a flow passage is bored on a valve body, and a temperature controller using the two-way valve.SOLUTION: A two-way valve for flow control includes: a valve body 6 that has a valve seat 8 comprising a columnar void, and in which a first port 9 through which fluid circulates is formed at one end part along an axial direction of the valve seat 8 and a second valve port 11 with a rectangular cross section through which fluid circulates is formed on a peripheral surface of the valve seat 8; a valve body 12 rotatably arranged in the valve seat 8 of the valve body 6, and formed into a shape that forms a part of a cylindrical shape, a central angle of the cylindrical shape preset so as to linearly change an opening area of the second valve port 11; and driving means 3 of rotationally driving the valve body 12.SELECTED DRAWING: Figure 2
