WATER-SAVING CHECK VALVE
Document Type and Number:
WIPO Patent Application WO/2022/121990
Kind Code:
A1
Abstract:
Provided in the present invention is a water-saving check valve, comprising: a valve body, a valve core, and a water-saving core. The water-saving core is fixedly arranged in the valve body and provided with a first water outlet channel and a second water outlet channel that are mutually independent. The valve core movably fits the water-saving core and moves between a first position and a second position in the axial direction of the valve body under the effect of water pressure. When the water pressure is high, the valve core is located at the first position and closes the first water outlet channel. When the water pressure is low, the valve core is located at the second position and opens the first water outlet channel. The second water outlet channel is in a normally open state. The water-saving check valve is capable of meeting a demand for a low-pressure large flow.
