Problems solved by technology

However, the existing casing cannot produce the ideal effect, that is, to prevent water from flowing into the sensor to completely eliminate the moisture in the gas to be measured
Moreover, it is difficult for such a casing to meet the test requirements of the industrial waterproof level, that is, it is difficult for the casing to withstand the spray of a certain pressure water column in this type of test, and water will inevitably be brought into the sensor

Embodiment Construction

[0031] In order to help those skilled in the art to accurately understand the subject matter claimed in the present application, the specific implementation manners of the present application will be described in detail below in conjunction with the accompanying drawings.

[0032] figure 1 A schematic diagram of an embodiment of a gas detector to which the present application relates is shown. The gas detector includes a detector body 10 and a cover 20 connected to the detector body 10 . see figure 2 , the probe main body 10 includes a mounting base 12 in which a sensing element (not shown) is disposed, and in the figure, the mounting base 12 is cylindrical in shape. The mounting base 12 also has an inlet 16, where a filter 14 is arranged, and the gas to be measured enters the detector main body 10 through the inlet along the direction of the solid arrow, and then contacts the sensing element. The processing device that works according to the input of the sensing element i...

Abstract

The invention discloses a gas detector having a waterproof grade, which comprises a detector body and a cover, wherein the detector body comprises a mounting base in which a sensing element is disposed, the mounting base is provided an inlet for a gas to be detected, the inlet defines an axis direction; and the cover has a circumferential wall defines an enclosing space inside the cover, the enclosing space has a proximal end and a distal end in the axial direction, the cover is attached to the mounting base such that the proximal end of the enclosing space is located near the inlet, a plurality of shutter elements are attached to the circumferential wall, each of the plurality of shutter elements is configured to form a passage through which a water flow passes between an exterior of thecover and the enclosing space and extends toward the distal end.

Description

technical field [0001] The present application relates to a detector for gas detection. Background technique [0002] Industrial gas detectors are used to detect flammable and explosive gases and toxic and harmful gases. Such gas detectors can be used, for example, in urban underground pipe gallery projects. All kinds of domestic water, urban water, and industrial wastewater are transported through the drainage pipes. In a closed pipeline, there are physical and chemical reactions of organic and inorganic substances, which may produce flammable and explosive gases and toxic and harmful gases, such as nitrogen oxides, including: nitrous oxide, nitrogen monoxide, trioxide Dinitrogen, dinitrogen tetroxide, dinitrogen pentoxide, etc., carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide, oxygen, methane, ammonia and other gases, when the flammable and explosive gases reach a certain concentration, there will be an explosion hazard. When the concentration of toxic ...
