Abstract
The invention discloses a gas detection device and a spherical gas detection probe structure specially used in a spiral gas chamber. The spherical gas detection probe structure is arranged in the spiral gas chamber; the gas detection device comprises a shell and a gas detection probe arranged in the shell, wherein the shell is a pipe body, arc-shaped reduced neckings are arranged in the pipe body at intervals, and a testing gas chamber with an arc-shaped concave space can be formed between each two reduced neckings; the gas detection probe is arranged in the arc-shaped concave space of the testing gas chamber, and a cleaning hole is formed in a position, opposite to the position of the gas detection probe, on another arc-shaped concave space of the testing gas chamber. The gas detection device overcomes the defect that a detection probe of an existing detection probe structure is not fully contacted with to-be-tested gas.
Description
Technical field
The present invention relates to gas detection technology field, specifically a kind of gas-detecting device for many gas detect and special spiral gas indoor location spherical gas detection probe structure.
Background technology
In recent years, along with country payes attention to aspects such as ecologic environment, production safety, food securities, increasing demand was had to many-sided detections such as toxic and harmful and food freshnesses.The data conversion module that many gas-detecting devices generally comprise detection probe, be electrically connected with detection probe, the PC communicated to connect with data conversion module and respectively with detect the sample gas gas supply mechanism and pure air organization of supply that box fluid is communicated with.Detection probe is as the most crucial parts of pick-up unit, and directly impact detects the accuracy of data.
Summary of the invention
Object of the present invention will provide a kind of gas-detecting device and dedicated test probe exactly, to improve the accuracy detecting data.
The present invention is achieved in that
Spiral gas indoor location spherical gas detection probe structure, the gas detection probe comprising housing and arrange in housing, described housing is body, and this body is arranged at intervals with arcuation necking down, forms the test air chamber with arc concave space between every two necking downs; Described gas detection probe is installed in an arc concave space of described test air chamber, and the position relative with described gas detection probe in another arc concave space of described test air chamber offers clean-out opening.
Described test air chamber is eight, is all provided with spherical detection probe in each air chamber.
Gas-detecting device, include spiral gas indoor location spherical gas detection probe structure, the gas detection probe that this sonde configuration comprises housing and arranges 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 every two necking downs; Described gas detection probe is installed in an arc concave space of described test air chamber, and the position relative with described gas detection probe in another arc concave space of described test air chamber offers clean-out opening.
The present invention adopts this structure, gas detection probe is positioned at the arc concave space of each detection air chamber, different detection probe is positioned at different air chamber, when therefore testing, not only impact is each other attenuated to minimum, and relative to existing detection probe structure, 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 each residual gas tested in rear each air chamber can get effective washing.In addition, this structure being intervally distributed with arcuation contractible neck, can make air-flow by time produce partial pressure differential because of the very fast change of the space size of front and back, alternately complete supercharging, decompression process, thus the inner circulation that formed is spread, increase 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.
Embodiment
The gas detection probe that spiral gas indoor location spherical gas detection probe structure comprises housing and arranges in housing, shown in Fig. 1, housing is body 1, two tube openings, is respectively air intake opening 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 every two necking downs; Described gas detection probe 2 is installed in the concave shaped space 7 of described test air chamber, and the position relative with described gas detection probe in another arc concave space of described test air chamber offers clean-out opening 3.Clean-out opening 3 is provided with the sealing-plug being easy to open, during gas detect, is stoppered sealing-plug, keep the sealing state in body.When detection probe needs to clean, open sealing-plug, can be cleaned probe and particle around thereof conveniently by the mode of gas purging by clean-out opening.In addition, also by clean-out opening installation and checking comparison probe, to check in indexs such as the aging attenuation degrees of measurement performance with probe.Test air chamber is eight, is all provided with spherical detection probe in each air chamber.
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.In addition, there is not dead angle in spiral gas indoor location spherical gas detection probe structure body, not only resistance to flow is little, and, due to noresidue space, previous impurity is detained and reduces, and then avoid the cross influence to testing result.Reserved cleaning sewage draining exit conveniently carries out blowdown, cleaning, probe verification, thus not only guarantees the accuracy of measurement, also maintains easily.
The detection probe of installing in spiral gas indoor location spherical gas detection probe structure of the present invention preferably adopts ball-type detection probe, it matches with the test air chamber in this spiral gas indoor location spherical gas detection probe structure, realizes the accurate detection of many gas.Its periphery is quartz crystal, adopts spheric probe can increase reaction surface of contact as much as possible in relatively narrow and small installing space, does not produce interference mutually again simultaneously.Under onesize erection space, spherical detection probe is larger than the reaction area of planar rondure detection probe, if the plane that same installation radius is r is 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 evenly and stress value is minimum, can make material doses reduce more than 30% ~ 45% simultaneously.In addition, spiral gas indoor location spherical gas detection probe structure floor area of the present invention is relatively little.
Gas-detecting device of the present invention, online test can be carried out, namely tested gas is drained into checkout equipment end and is carried out the test of real-time online formula when continuing to flow, the connecting circuit analysis of related data through being connected with spheric probe produces, and in real-time input database, when reaching threat data, produce the object that electric signal warning exports.
