摘要： The invention provides a waterway switch switching valve, which comprises: valve body, main control valve core and waterway control valve core; the valve body comprises a water inlet channel, a first water outlet and a second water outlet, the number of waterway control valve core corresponds to the number of water outlets one by one, and is divided into the first and second waterway control valve core; the first waterway control valve core and the second waterway control valve core are respectively installed in the valve body; The valve body also comprises a first waterway arranged between the water inlet channel and the first waterway control valve core; and a second waterway between the first waterway control valve core and the second waterway control valve core; when the first waterway control valve core is opened, the first waterway control valve core connects the first waterway with the first water outlet; when the first waterway control valve core is closed, the first waterway control valve core connects the first waterway with the second waterway; when the second waterway control valve core is opened, the second waterway communicates with the second water outlet. The above waterway switch switching valve ensures that there is only one waterway discharge water at most.

摘要： A cool water discharging method and a switch valve includes a valve body and a valve spool. The valve body is disposed with a thermosensitive module, an inlet passage, a first outlet passage, and a second outlet passage. The valve body has a cool water discharging passage connected to the inlet passage, a discharging hole connecting the first outlet passage and the cool water discharging passage and an air suction hole connecting the second outlet passage and the cool water discharging passage. When discharging cool water, water flows to the cool water discharging passage rapidly, the air in the second outlet passage is absorbed to the cool water discharging passage. The residual cool water in the second outlet passage is absorbed to the cool water discharging passage through the air suction hole and discharged out with the residual cool water in the first outlet passage.

摘要： An automatically resettable press-type switching valve includes a valve housing, an operating portion, a driven rod, a water blocking member, and a resetting member. The valve housing is formed therein with an inlet and outlet passages. A water blocking seat is provided between the inlet and outlet passages. The operating portion drives the driven rod to move axially so as to form a forward pressure difference or reverse pressure difference between two opposing sides of the water blocking member, by which the water blocking member is pushed to move axially with the driven rod. The resetting member is drivingly connected with the water blocking member, when there is no water pressure at a side of the inlet passage, the resetting member drives the water blocking member to separate from the water blocking seat, and the inlet passage is communicated with the outlet passage.
