The electric actuating mechanism applied to the steam system generally has a severe working environment, for example, high-temperature steam leakage often occurs in the starting and stopping or production adjusting process of the steam system, the steam leaks out from a valve flange or a valve rod, once the steam leaks, the steam is directly sprayed onto the electric actuating mechanism, and the temperature and the humidity of the surrounding environment of the actuating mechanism are rapidly increased. The highest working environment temperature of a common electric actuating mechanism is about 70 ℃, the environmental humidity is less than 95%, the working environment requirement of the intelligent integrated actuating mechanism is higher, and when the steam leakage amount is larger, the leakage time is longer, and the damage probability of the electric actuating mechanism is higher.
The current commonly used heat insulation protection measures mainly comprise the following two schemes: one is to coat high-temperature-resistant heat-insulating coating outside the electric actuator to achieve the heat-insulating effect, and the other is to manufacture a housing by using heat-insulating material to wrap the whole electric actuator, however, either scheme has some defects and shortcomings. Firstly, they all can produce some negative effects to debugging or maintenance of electric actuator, because the debugging or maintenance of electric actuator all need open its shell, consequently scribble high temperature resistant thermal-insulated material again or install high temperature resistant heat insulation housing again after every maintenance or debugging, and secondly, high temperature resistant thermal-insulated coating is with higher costs, is inconvenient for the field implementation. The high-temperature resistant heat insulation cover wraps the whole electric actuating mechanism, and the defects exist in heat dissipation, operation and maintenance.
