THREE-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2017/099380
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a three-way valve that separately includes a valve member for supplying heating water and a valve member for performing a bypass function, and allows the valve members to independently operate, thereby enhancing durability. To achieve this, the three-way valve of the present invention comprises: a valve housing having an inlet, a first outlet, and a second outlet integrally formed therewith, wherein heating water is introduced into the valve housing through the inlet, and the heating water introduced through the inlet is supplied to a site to be heated through the first outlet and is supplied to a heat exchanger for hot-water supply through the second outlet; a first valve member configured to be opened/closed to selectively open one of the first and second outlets; a drive unit providing a driving force to open/close the first valve member; and a second valve member operating independently of the first valve member, wherein the second valve member opens a bypass hole in order to allow the heating water to flow toward the second outlet when the pressure of the heating water at the first outlet side exceeds a preset pressure in a state in which the first valve member opens the first outlet and closes the second outlet.
