| Abstract: | A new type of thermostatic steam trap is developed by exploiting the property of shape memory alloy (SMA). Its structure, operation principle, and actuation feature are discussed, and the design method of SMA spring is described also. Comparing the SMA steam trap with the bimetallic strip actuator, it can be found that the development of SMA steam trap have favorable prospects. |
