The temperature sensing element 9 is formed by attaching bimetallic strips with different thermal coefficients, is arranged on the outer side of the cover body 5, and can be of a conventional structure such as a strip type or a coil spring type (in the embodiment, one end of the temperature sensing element 9 is connected with the valve plate shaft 8, and the other end is connected or fixed to the end cover 7). One end of the valve plate shaft 8 is connected to the temperature sensing element 9, and the other end is directed to the driving shaft 1 through the cover 5 (i.e., through the cover 5). The valve plate 7 is propped against the surface of the driven plate 6 and can move relative to the driven plate 6 under the drive of the valve plate shaft 8; in this embodiment, the other end of the valve plate shaft 8 may be square to connect with the valve plate 7 through a square hole, and when the valve plate shaft 8 rotates with its own axis as a rotation axis, the valve plate 7 may be driven to move synchronously with respect to the driven plate 6.
