Abstract

The invention belongs to the field of anti-explosion electrical facilities. The anti-explosion touch screen comprises a box body [11], a box cover [2], a resistance touch screen [4], a touch screen control plate [7], window glass [5], wherein the box body [11] and the box cover [2] are fastened to form a sealing space. A hole larger than the resistance touch screen is formed in the box cover welded with a fixing column which is matched with a screw to fix a window pressure plate and to press a window rubber mat and the window glass on the box cover. The window glass and the fixing column are sealed by epoxy resin glue. The resistance touch screen is stuck on the window glass. The anti-explosion touch screen is characterized by further comprising a polyvinyl chloride (PVC) film [3] covered on the resistance touch screen [4] and guard grating [19] fixed on the inner side of the box body, an audio speaker device [27] welded inside the box body, and fire net [16] arranged inside the audio speaker device [27].

Description

technical field [0001] The invention belongs to the field of explosion-proof explosion-proof electrical equipment, and specifically relates to an explosion-proof touch screen used in an environment where the explosive gas environment is zone 1 and zone 2, has levels IIA and IIB, and explosive gas or steam mixtures in groups T1-T6. Background technique [0002] At present, more and more explosion-proof electrical appliances are used in hazardous places with explosive gas atmospheres, especially in hazardous places in Zone 1 and Zone 2 and places with relatively humid and dusty gas environments; real-time parameter setting and operation of field devices are required , and timely alarm the failure of the field equipment, so it is necessary to set the touch screen. [0003] For example, the mining touch screen designed and produced by Xuzhou Baodi Electric Co., Ltd. mainly includes an explosion-proof box, an intrinsically safe box installed together with the explosion-proof box,...
