Embodiment
The present invention proposes a kind of pair of air slot bandwidth detecting sensor, and it makes simple, and production cost is low, can use in various rugged environments, realizes having very high practical value easily.
The first embodiment of two air slot bandwidth detecting sensors involved in the present invention as shown in Figure 1.Two parts mainly are set on the support 5 to be formed, leave air cleft detection space 9 between these two parts, a part is that the first air cleft forms the unit, comprise by the first inlet plate 6 and the first air cleft generation board 4 and be bolted to connection the first air chamber 11 that consists of, and between the first inlet plate 6 and the first air cleft generation board 4 for being tightly connected, such as Fig. 3, Fig. 4 and shown in Figure 5, wherein, Fig. 3 has shown that the first air cleft forms the inner structure of unit and air cleft detecting unit, one side of the first inlet plate 6 arranges inlet suction port 7 is installed on the first air intake opening 10, the first air intake openings 10.The first slit 12, the first inlet suction ports 7 are set on the first air cleft generation board 4 to link to each other with source of the gas 8 with regulator.
Another part of sensor is to form the air cleft detecting unit that the unit is fixed together by bolt and the first air cleft, this air cleft detecting unit comprises the check-out console 3 that is fixedly connected with the first air cleft generation board 4, test chamber 13 is set on the check-out console 3, test chamber 13 is interior to arrange some gas detecting tubes 2, and the position in the first slit 12 on the position of gas detecting tube 2 and the first air cleft generation board 4 is corresponding.Gas detecting tube 2 with link to each other with the conversion of the signals collecting of gas electric transducer and computer information processing system 1.Test chamber 13 is interior, and that the quantity of gas gas detecting tube 2 is set is more, and the precision of detection is just higher.
During work, to slowly send into steel in the air cleft detection space 9 of this sensor, as shown in Figure 2, open source of the gas 8, gases at high pressure import in the first air chamber 11 by the first inlet suction port 7, form voltage stabilizing gas, and form laminar flow gas by the effect in the first slit 12, be air cleft, width is 0.03mm～0.05mm.When interior through out-of-date from air cleft detection space 9 without the band steel, laminar flow gas will enter gas detecting tube 2, and records signal by signals collecting conversion and the computer information processing system 1 with gas electric transducer.The band steel is interior through out-of-date from air cleft detection space 9 when having, because gas can not penetrate the band steel, be with steel to shelter from by the laminar flow gas that the first air cleft generation board 4 produces, so that corresponding being covered with steel in the gas detecting tube 2 partly do not receive gas signal, do not covered with steel that the gas detecting tube 2 of part is interior can to receive gas signal, will be detected by the computer information processing system 1 with the pneumatic-electric signal Collect conversion that links to each other with gas detecting tube 2 like this parameters such as width with steel.
The second embodiment of the present invention is similar to the first example structure, and difference is that the second air cleft formation unit that is connected with source of the gas 8 with regulator also is set on the support 5, as shown in Figure 6.It is substantially the same with the first air cleft formation cellular construction that this second air cleft forms cellular construction, such as Fig. 8, Fig. 9 and shown in Figure 10, wherein, Fig. 8 has shown that the second air cleft forms the inner structure of unit, be that inside arranges the second air chamber 11, the second inlet suction port 7 of outer setting and the second air chamber 11 ' be connected ' and produce the second slit 12 of the second air cleft '.Need to prove that this second air cleft forms the second slit 12 in unit ' parallel with the first slit 12 of the first air cleft formation unit, it is perpendicular that the second air cleft of the second slit 12 ' generation passes the direction of the first air cleft that air cleft detection space 9 and its direction and described the first slit 12 produce, and in use, do not pass through from the air cleft detection space 9 that the first air cleft forms between unit and the air cleft detecting unit with steel, but in the space between the first air cleft formation unit and the second air cleft formation unit, pass through test-accepting.
The first air cleft forms the working position of unit, the second air cleft formation unit and air cleft detecting unit and puts as shown in Figure 6.The first air cleft formation unit and air cleft detecting unit namely form the laminar flow gas of horizontal direction in upper horizontal positioned.The second air cleft forms the unit in lower vertical placement, and the laminar flow gas direction that namely forms blows to the air cleft detection space 9 of the first air cleft generation board 4 straight up, and two-layer gas body is orthogonal.
During work, as shown in Figure 7, open source of the gas 8, gas will form the first air chamber 11 of unit and the second air chamber 11 that the second air cleft forms the unit ' interior generation voltage stabilizing gas at the first air cleft, and by the first slit 12 and the second slit 12 ' generation the first air cleft and the second air cleft, the first air cleft and the second air cleft interfere at air cleft detection space 9, and result of interference makes two air clefts flow to from different directions atmosphere, and two air cleft width are 0.03mm～0.05mm.Regulate the gaseous tension of the first air cleft and the second air cleft and can control the flow direction that two air clefts are interfered rear gas, regulate regulator in the present embodiment so that the first air cleft forms the gaseous tension of unit greater than the gaseous tension in the second air cleft formation unit.To pass through from the space that the first air cleft forms between unit and the second air cleft formation unit with steel.When not being with steel to pass through, by regulating the gaseous tension of the first air cleft and the second air cleft, so that do not receive gas signal in the gas detecting tube 2, when having the band steel to pass through, because forming unit generation laminar flow gas, the second air cleft is with steel to block, at this moment, the gas signal that only has the first air cleft to form the unit generation can be received by gas detecting tube 2, and in computer system, show, the gas signal of the first air cleft that is not blocked with steel just can't be received by gas detecting tube 2, also just in computer system, can't show, can realize thus the measurement of bandwidth.
This sensor construction is simple, easy to use, by adopting the mode of gas micrometer, to measuring accurately with the bandwidth of steel and the quality of plate face, take full advantage of the character of air cleft, come the wide and plate face quality of check-out console by the variation that detects air cleft gas, production cost is low, can in various rugged environments, use, realize having very high practical value easily.
Obviously; above-described embodiment only is for giving an example of doing clearly is described; and be not limitation of the invention; for the person of ordinary skill of the art; can also make on the basis of the above description other multi-form variations; the form of the composition of air chamber for example; air cleft detecting unit and the first air cleft formation unit can not be fixed together the gas signal that only need make gas detecting tube can receive air cleft and get final product; etc.; here also need not carry out exhaustive for all embodiments; and the apparent variation that proposes thus still is within protection scope of the present invention.
