Abstract

The present invention relates to an indicator housing for preventing dew condensation. The indicator housing for preventing dew condensation comprises: an indicator which is connected to an air motor operated valve actuator (AOV) and displays a power situation of the AOV; a box type case into which the indicator is inserted and includes one opened surface; and a circular shaped cover which seals the indicator by being combined with the one opened surface of the case with a bolt. The cover includes an outer cover which is formed in a double circular shape and includes a cross section of an L-shape, and an inner cover which protrudes from an outer circumferential surface of the outer cover and includes a cross section of an L-shape. A window is installed between an O-ring and a snap ring in the outer cover. Since an indicator name plate is installed between the inner cover and the outer cover to be faced to a rectangle ring, a case inner air passage to the window of the outer cover is disconnected. Case inner air to the window of the outer cover is disconnected by forming an inner edge of the inner cover in a round shape. The indicator name plate is combined with the indicator by being processed with a Teflon seal. Therefore, the present invention can prevent the dew condensation which occurs in an indicator window by external temperature change by using the cover having the double circular shape composed of the outer cover and the inner cover. The present invention doubly prevents the dew condensation which occurs in the indicator window by disconnecting air which occurs in the inner AOV.
