Description
Technical field
The present invention relates to gas detection technology field, specifically a kind of gas-detecting device for many gas detecting and special spiral gas indoor location spherical gas detection probe structure.
Background technology
In recent years, along with the aspects such as ecological environment, production safety, food safety are paid attention to by country, many-sided detections such as toxic and harmful and food freshness there is increasing demand.Many gas-detecting devices generally comprise data conversion module that detection probe electrically connects with detection probe and data conversion module communication connection PC and respectively with the sample gas gas supply mechanism of detection box fluid communication and pure air organization of supply.Detection probe, as the most crucial parts of detecting device, directly affects the accuracy of detection data.
Summary of the invention
Present invention aim to provide a kind of gas-detecting device and dedicated test probe, to improve the accuracy of detection data.
The present invention is achieved in that
Spiral gas indoor location spherical gas detection probe structure, including housing and the gas detection probe arranged in housing, described housing is body, and this body is arranged at intervals with arcuation necking down, is formed and have the test air chamber in arc concave space between each two necking down；Described gas detection probe is installed in an arc concave space of described test air chamber, offers clean-out opening on the position relative with described gas detection probe in another arc concave space of described test air chamber.
Described test air chamber is eight, is mounted on spherical detection probe in each air chamber.
Gas-detecting device, include spiral gas indoor location spherical gas detection probe structure, this sonde configuration includes housing and the gas detection probe arranged in housing, described housing is body, this body is arranged at intervals with arcuation necking down, forms the test air chamber with arc concave space between each two necking down；Described gas detection probe is installed in an arc concave space of described test air chamber, offers clean-out opening on the position relative with described gas detection probe in another arc concave space of described test air chamber.
The present invention adopts this structure, gas detection probe is positioned at the arc concave space of each detection air chamber, different detection probe are positioned at different air chamber, when therefore testing, not only impact each other is attenuated to minimum, and, relative to existing detection probe structure, the detection probe structured testing gas gas consumption of the present invention is minimum.The present invention offers clean-out opening on the wall body relative with detection probe installation site, to ensure that the residual gas tested in rear each air chamber can get effective washing every time.Additionally, this structure being intervally distributed with arcuation contractible neck, because the very fast change of the space size of front and back produces partial pressure differential when can cause air flow through, it is alternately accomplished supercharging, decompression process, so that being internally formed circulation diffusion, increasing probe contacts probability, the detection probe solving the existence of existing detection probe structure contacts insufficient shortcoming with gas to be measured.
Accompanying drawing explanation
Fig. 1 is the structural representation of spiral gas indoor location spherical gas detection probe structure of the present invention.
Detailed description of the invention
Spiral gas indoor location spherical gas detection probe structure include housing and in housing arrange gas detection probe, shown in Fig. 1, housing is body 1, both ends open, respectively air inlet 5, gas outlet 4.This body 1 is arranged at intervals with arcuation necking down 6, forms the test air chamber with hemispherical concave shaped space 7 between each two necking down；Described gas detection probe 2 is installed in the concave shaped space 7 of described test air chamber, offers clean-out opening 3 on the position relative with described gas detection probe in another arc concave space of described test air chamber.Clean-out opening 3 is provided with the sealing-plug being prone to open, during gas detecting, is stoppered sealing-plug, keep the sealing state in body.When detection probe needs to clean, open sealing-plug, conveniently by the mode of gas purging, probe and particulate matter about can be carried out by clean-out opening.It addition, pop one's head in also by clean-out opening installation and checking comparison, with inspection in indexs such as the aging attenuation degrees of measurement performance with probe.Test air chamber is eight, is mounted on spherical detection probe in each air chamber.
The spiral gas indoor location spherical gas detection probe structure of the present invention is used for gas-detecting device, and the other parts of gas-detecting device can adopt any attainable structure of the prior art.
Spiral gas indoor location spherical gas detection probe structural capacity designed by the present invention is little, can reduce gas usage, improves detection efficiency.It addition, be absent from dead angle in spiral gas indoor location spherical gas detection probe structural tube body, not only flow resistance is little, is additionally, since noresidue space so that previous impurity is detained minimizing, and then avoids the cross influence to testing result.Reserved cleaning sewage draining exit conveniently carries out blowdown, cleaning, probe verification, thus not only guaranteeing the accuracy measured, also maintains easily.
The detection probe installed in the spiral gas indoor location spherical gas detection probe structure of the present invention is preferably with ball-type detection probe, it matches with the test air chamber in this spiral gas indoor location spherical gas detection probe structure, it is achieved the accurate detection of many gases.Its periphery is quartz crystal, adopts spheric probe can increase reaction contact surface in relatively narrow and small installing space as much as possible, does not produce mutually again interference simultaneously.Under an equal amount of erection space, spherical detection probe is bigger than the response area of planar rondure detection probe, if installing the plane that radius is r to be equally converted into the spheric probe of same area, corresponding volume is little, so, the installation dimension of plane probe is 2 times of spherical installation.Under same installation radius, spherical surface area is original 4 times.Spheric probe is compared with original plate probe, and when volume, pressure are identical, structurally internal stress is uniform and stress value is minimum, and material doses can be made to reduce more than 30% ~ 45% simultaneously.Additionally, the spiral gas indoor location spherical gas detection probe structure floor space of the present invention is relatively small.
The gas-detecting device of the present invention, online test can be carried out, namely tested gas is drained into detection equipment end and is carried out the test of real-time online formula when not stopping, the related data connection circuit analysis through being connected with spheric probe produces, and in real time in input database, produce the signal of telecommunication when reaching threat data and report to the police the purpose of output.
