WIPO Patent Application WO/2020/052644
Kind Code:
A1
Abstract:
Disclosed is a waterway switching valve, comprising: a valve body (1), a switching operating member (2) and a switching member (3); the valve body (1) has a water inlet (14), a first water outlet (15) and a second water outlet (16); the switching operating member is linked with the switching member; the switching member is provided with a first sealing element (31), a first pressure relief part (32), a second pressure relief part (33) and a second pressure relief part (34) in sequence along the moving direction; the valve body is provided with a first pressure formation cavity (11) and a second pressure formation cavity (12)along the moving direction of the switching member; the valve body is provided with a blocking part (13) between the first pressure formation cavity and the second pressure formation cavity; the blocking part includes a first runner (131) and a second runner (132) isolated from each other; the first runner and the second runner are connected to the first water outlet and the second water outlet, respectively; when the switching operating member drives the switching member to move to a position corresponding to an opening formed by the first sealing cavity and the first pressure formation cavity, the first pressure formation cavity is in a pressure building state and is driven by the water pressure to fit to the upper end surface of the blocking part in a sealing manner; and the first water outlet is isolated from the water inlet. The waterway switching valve is small but can produce high flow rate.
