Abstract
The invention discloses a visual explosion-proof cover of a gas detector. The visual explosion-proof cover comprises a calibration cover, a lower cover, a stainless steel net threaded ring, an upper cover, a glass window, a gland, a threaded plug, a nut and the like, wherein the interior of the calibration cover is connected with the lower cover; the bottom of the inner side of the lower cover is connected with the stainless steel net threaded ring; the top end of the lower cover is connected with the bottom end of the upper cover; the glass window is arranged on the side face of the upper cover; the gland is arranged on the outer side of the glass window; the threaded plug and the nut are arranged at the top end of the upper cover. According to the cover, the glass window is arranged on one side of the upper cover to realize a good visual effect, and can effectively help to detect the situation in a product. An encapsulation explosion-proof joint face is added between the glass window and the upper cover, thereby effectively improving an explosion-proof effect. All parts in the cover are sealed well, so that the detection accuracy of the detector is effectively improved.
Description
Technical field
the present invention relates to a kind of detector anti-explosion cover, particularly relate to a kind of visual gas detector anti-explosion cover.
Background technology
combustible gas probe adopts catalysis element and catalytic combustion type transducer, and inside is made up of detecting element and compensating element.Two elements and standard resistor are connected into resistance bridge, without bridge balancing during fuel gas, when the fuel gas in air diffuses to transducer detecting element, namely oxidation reaction is produced on its surface, detecting element temperature raises, and resistance becomes large, bridge road disequilibrium, through amplifying adjustment, export the ModBus standardized digital signal linear with combustable gas concentration.
detector for poisonous gas adopts electrochemical element and electrochemical transducer[sensor.When the poisonous gas in air diffuses to working sensor electrode, namely produce oxidation or reduction reaction on its surface, work electrode produces reverse current, through amplifying adjustment, exports the ModBus standardized digital signal linear with detecting gas concentration.
at present, mostly the antiknock device of the gas detector on market is to utilize anti-explosion cover structure, adopt the mode of flame proof, prevent from detector inside from producing explode excessive or prevent detector extraneous explosion electuary internal unit, but, its explosion-proof performance is general, and majority can only play the effect preventing device interior explosion caused.
Summary of the invention
the object of this invention is to provide one and there is visual function, can be explosion-proof, the visual gas detector anti-explosion cover of one of available protecting gas detector.
in order to realize object of the present invention, the present invention is achieved by the following technical solutions: a kind of visual gas detector anti-explosion cover, comprise the structures such as calibration mask, lower cover, stainless (steel) wire volution, upper cover, windowpane, gland, screw plug, nut, it is characterized in that: calibration mask inside is connected with lower cover, lower cover inside bottom is connected with stainless (steel) wire volution, lower cover top is connected with upper cover bottom, the side of upper cover is provided with windowpane, the outside of windowpane is provided with gland, and upper cover top is provided with screw plug and nut.
junction between described upper cover, lower cover, stainless (steel) wire volution is equipped with O RunddichtringO.
