| 摘要 |
<p>The invention relates to a thermostatic mixing valve (10) comprising a hollow body (11) having a first inlet (12), a second inlet (13), and an outlet (14) in fluid communication with the first inlet (12) and/or the second inlet (13) via a mixing chamber (15). The flow through the valve is controlled by an axially extending thermostatic actuator (16) comprising a stem (17), an enlarged portion (18) and a heat sensitive bulb (19), said bulb extending into the mixing chamber (15). Te thermostatic actuator (16) is arranged to be axially displaced between a first end position in which only the first inlet is connected to the outlet (14) and a second end position in which only the second inlet is connected to the outlet (14). The thermostatic actuator (16) is displaced in a sleeve member (23) arranged to restrict the flow of water from the second inlet (13) past the enlarged portion of the thermostatic actuator (16) during its axial displacement until the thermostatic actuator (16) reaches the second end position.</p> |
