Title:
DUCT OPENING/CLOSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/122479
Kind Code:
A1
Abstract:
Disclosed is a duct opening/closing device that can be more compact and can promptly open/close a main valve—which is for starting and stopping water supply—while causing the instantaneous flow rate of water supply to be constant. In a flush valve (CV) as the duct opening/closing device, a fixed flow rate means is incorporated that operates to maintain a constant main flow rate flowing from a primary-side inner duct (20) to a secondary-side inner duct (30); the fixed flow rate means has a fixed flow rate valve body (44) and a fixed flow rate valve seat, and operates so as to adjust the distance between the fixed flow rate valve body (44) and the fixed flow rate valve seat; and a main valve body (42) and the fixed flow rate valve body (44) are formed as an integrated valve member (40).
