A separation system for recycling cold water and a separation valve. The separation valve comprises a valve body, left and right ends being sealed by means of end covers. A water passing channel (19) is provided in the middle of the valve body. The left and right ends of the valve body are a separation cavity (16) communicated with a hot water inlet pipe and a backflow cavity (21) communicated with a cold water inlet pipe, respectively. A hot water cavity communicated with a hot water outlet (9) is provided on the left side of the separation cavity (16). A hollow piston (15) is disposed in the separation cavity (16), a water passing hole being provided in the side wall of the piston (15). The left end of the piston (15) is provided with a piston end cover (6) with a water passing hole (5). A temperature sensing element (2) is mounted in a hollow body of the piston (15). A sealing disc (3) is mounted on the temperature sensing element (2). The sealing disc (3) axially seals the water passing hole (5) of the piston end cover (6) by means of a supporting spring (17) mounted at the right end of the temperature sensing element (2). A one-way valve (1) is disposed between the backflow cavity (21) and the water passing channel (19). The temperature sensing element (2) does not drive the piston (15) to slide, a backflow channel of cold water cannot be mistakenly opened so as not to cause that a cycle cannot stop, and the piston (15) will not move back and forth in the separation cavity (16) so as not to generate vibration and noise. |
