Description
Technical field
The present invention relates to gas sampling, particularly multi-channel sampling device.
Background technology
Multi-channel sampling device can utilize a plurality of sampling channels to realize and a plurality of species be sampled simultaneously, each sampling channel is joined a sample can, in each sample can, place multi-disc sampling membrane and denuder, then sample can is linked on sampling thief main frame and starts to sample, after having sampled, take off sample can and change filter membrane and denuder, again sample can access host is started subsequently to the next sampling period.Here sample can will often remove and install as the carrier of filter membrane and denuder, require disassembly and assembly structure fast, reliably, and installation rear port place will guarantee impermeability.
There is following defect in common sample can structure at present:
1. because sample can is dismounting manually, in order to prevent omitting, before starting to sample, whether software can be installed on sampling thief main frame by automatic decision sample can, generally to judge by the electronic components such as hall device, approach switch, contact switch are set, not only can bring extra cost, and because sample can is in outdoor environment, thereby the failure probability initiating system erroneous judgement of this type of electronic component of increase greatly.Each sample can wants cabling in sampling thief main frame in addition, has strengthened the difficulty of main frame water proof and dust proof and the complicacy of cabling layout;
2. the hermetically-sealed construction at sample can and host interface place is simple, after sample can takes off, host interface is completely unlimited, easily by steam, dust, raise the foreign matters such as wadding, winged insect and invade in main frame gas circuit, affect the life-span of each device in air-channel system, cause not clear sampling fault.
Summary of the invention
In order to solve the deficiency in above-mentioned prior art scheme, the invention provides a kind of simple in structure, prevent allotrylic multi-channel sampling device.
The object of the invention is to be achieved through the following technical solutions:
A multi-channel sampling device, described multi-channel sampling device comprises:
At least two sampling containers, described sampling container has import and outlet, and described outlet is arranged on the fabricated section of sampling container one end hollow;
The sample lines corresponding with sampling container quantity, arranges flow metering device in described sample lines, sample lines has and is suitable for the deep entrance point of described fabricated section; Seal is arranged in described entrance point, and elastomeric element connects described seal, makes seal seal the import of sample lines; The inflow point of sample lines is provided with O-ring seal, and described O-ring seal mates with described fabricated section;
Sampling pump, described sampling pump is communicated with described sample lines.
According to above-mentioned sampling apparatus, alternatively, described sampling apparatus further comprises:
Gas compartment, the input end of described gas compartment is communicated with the output terminal of described corresponding with sampling container quantity sample lines, and sampling pump is communicated with the output terminal of gas compartment.
Compared with prior art, the beneficial effect that the present invention has is:
1, sampling gas circuit can self sealss, without human intervention, automatically protect each important devices in gas circuit not encroached on by foreign matter;
2, without increasing extra cost, whether the sample can that directly utilizes the existing flow sensor of system to get final product each sampling channel of automatic decision is installed;
3, self sealing structure integrated level is high, and not containing electronic component, can not increase the complicacy of system.
Accompanying drawing explanation
With reference to accompanying drawing, disclosure of the present invention will be easier to understand.Those skilled in the art hold intelligible: these accompanying drawings are only for illustrating technical scheme of the present invention, and are not intended to protection scope of the present invention to be construed as limiting.In figure:
Fig. 1 is according to the structure diagram of the multi-channel sampling device of the embodiment of the present invention 1;
Structure diagram when Fig. 2 is separated according to fabricated section in Fig. 1, sample lines;
Structure diagram when Fig. 3 inserts sample lines according to fabricated section in Fig. 1.
Embodiment
The following declarative description in Fig. 1-3 optional embodiment of the present invention with instruction those skilled in the art, how to implement and to reproduce the present invention.In order to instruct technical solution of the present invention, simplified or omitted some conventional aspects.Those skilled in the art should understand that be derived from the modification of these embodiments or replace will be within the scope of the invention.Those skilled in the art should understand that following characteristics can combine to form a plurality of modification of the present invention in every way.Thus, the present invention is not limited to following optional embodiment, and only by claim and their equivalent, is limited.
Embodiment:
Fig. 1 has schematically provided the structure diagram of the multi-channel sampling device of the embodiment of the present invention, and as shown in Figure 1, described multi-channel sampling device comprises:
At least two sampling containers 11, described sampling container 11 has import and outlet 14, and described outlet 14 is arranged on the fabricated section 13 of sampling container 11 one end hollows, as shown in Figure 2,3;
The sample lines corresponding with sampling container quantity, arranges flow metering device 31 in described sample lines, as flow sensor, sample lines has and is suitable for the deep entrance point 21 of described fabricated section 13; Seal 22 is arranged in described entrance point 21, and elastomeric element 23, as spring, connects described seal 22, makes seal 22 seal the import of sample lines; The inflow point of sample lines is provided with O-ring seal 24, and described O-ring seal 24 mates with described fabricated section 13;
Sampling pump 41, described sampling pump 41 is communicated with described sample lines;
Gas compartment 51, the input end of described gas compartment 51 is communicated with the output terminal of described corresponding with sampling container quantity sample lines, and sampling pump 41 is communicated with the output terminal of gas compartment 51;
Valve 61, described valve 61 is in described sample lines, for regulating the gas flow of pipeline.
The course of work of above-mentioned multi-channel sampling device is:
When certain sample lines does not need sampling container is installed, this pipeline is self-packing: under the effect of elastomeric element 23, seal 22 is blocking up the import of sample lines, thereby prevents foreign matter intrusion, as shown in Figure 2;
When needs are installed sample can, the fabricated section 13 of sampling container backs down described seal 22, elastomeric element 23 is compressed, sample lines is connected with outside gas circuit, O-ring seal 24 has guaranteed the sealing between the entrance point 21 of sampling container and sample lines, as shown in Figure 3, now opens sampling pump 51, the numerical value of flow sensor can reach preset value afterwards, can judge accordingly whether sampling container is in place.
