Thermal insulation device for steam system with information transmission function

Abstract

The invention discloses a thermal insulation device for a steam system with an information transmission function. The thermal insulation device is arranged between an electric execution mechanism anda valve body, and comprises a cover body, a temperature sensing unit, a temperature transducing unit, a DCS unit and a short message sending unit; the cover body is arranged between the electric execution unit and the valve body; and the temperature sensing unit is arranged on the cover body, and is connected with the temperature transducing unit, the DCS unit and the short message sending unit insequence. The thermal insulation protection can be provided to the electric execution mechanism on the steam system; and the operation condition of the steam system can be mastered in real time through temperature information acquisition, so that the energy is stably supplied for transmission of the steam system.

Description

technical field [0001] The invention relates to a safe operation system of an electric actuator in steam transmission, and more specifically relates to a thermal insulation device with information transmission function used in a steam system. Background technique [0002] Steam transmission pipelines are usually equipped with electric shut-off valves and electric regulating valves. One is to realize steam energy transmission, and the other is to control the flow, pressure and temperature of supplied steam. The advantages of using electric actuators are simple, flexible operation, labor-saving and time-saving , can also be operated and monitored remotely, which is widely used in the field of steam transmission, but the electric actuator also has its own weaknesses, whether it is an ordinary switch type actuator or an electric actuator supporting an integrated control unit device, its protection performance and There are certain requirements for the ambient temperature. Under ...

AI Technical Summary

Problems solved by technology

First, they will all have some negative effects on the commissioning or maintenance of the electric actuator. Since the commissioning or maintenance of the electric actuator needs to open its shell, it is necessary to reapply high-temperature heat-resistant insulation materials or Re-install the high-temperature-resistant heat-insulating shell. Second, the cost of high-temperature-resistant heat-insulating coating is relatively high, which is not convenient for on-site implementation

The high-temperature heat-insulating casing wraps the entire electric actuator, so there are defects in heat dissipation, operation and maintenance.
