Description
Technical field
The invention belongs to sampler technical field, and in particular to a kind of online Fast active sampling valve.
Background technology
In sample detection apparatus, generally sampled, analyzed using mass spectrograph and chromatograph.Due to mass spectrograph and chromatogram
It is few that instrument is respectively provided with amount of samples, the advantages of separation and identification are carried out simultaneously, therefore, mass spectrograph and being widely used in of chromatograph
Learn, chemical industry, environment, the energy, medicine, sports medical science, science and technology concerning criminal matters, life science, the every field such as material science.But
In vigorous reaction experiment, mass spectrograph and chromatograph also have respective shortcoming, and because vigorous reaction speed is fast, product is in a short time
Change, chromatograph can not moment complete analyze, although but mass spectrograph can realize quick analysis, its price hold high
It is expensive so that experimental cost is improved.
The content of the invention
It is an object of the invention to overcome disadvantages mentioned above present in prior art, there is provided a kind of reasonable in design, structure is simple
Single online Fast active sampling valve, the sampling valve can during Quick Acquisition vigorous reaction different periods product, experimenter can be first
It is sampled using the sampling valve, sample is slowly then analyzed by chromatograph again, so as to reduces experimental cost.
To achieve these goals, the technical solution adopted by the present invention is as follows：A kind of online Fast active sampling valve, including valve body
With the rotary spool above valve body, outer tunnel and internal channel, outer tunnel are respectively equipped with the outward flange of valve body and inward flange
With internal channel in approximately the same plane, sample holes and stock layout hole are respectively equipped with outer tunnel and internal channel；Along one week on valve body
Several quantitative loop injection ports and several quantitative loop nesting ports are evenly provided with, quantitative loop injection port is in quantitative loop nesting port
Periphery, and quantitative loop injection port and quantitative loop nesting port one-to-one corresponding, one-to-one quantitative loop injection port and quantitative loop stock layout
Quantitative loop is provided between mouthful；Position corresponding with any one quantitative loop injection port and a quantitative loop nesting port on rotary spool
On the exit orifice that is respectively equipped with exit orifice and endoporus, rotary spool and endoporus be connected respectively with the outer tunnel and internal channel on valve body
It is logical；Rotary spool rotates corresponding with any one quantitative loop injection port and quantitative loop nesting port on valve body to exit orifice and endoporus
When, the quantitative loop on the position is connected with outer tunnel and internal channel, and quantitative loop is sampled.
In the present invention, it is preferred to, valve body and rotary spool are in the form of annular discs.
The beneficial effects of the invention are as follows：The sampling valve of the present invention is simple in construction, can gather reaction in vigorous reaction experiment
During product, experimenter can first with the sampling valve gather sample, then by chromatograph etc., other analytical equipments are slow again
Slowly sample is analyzed, without using expensive spectrometer analysis sample, reduces experimental cost.

Embodiment
For a further understanding of the present invention, with reference to the accompanying drawing in the embodiment of the present invention, in the embodiment of the present invention
Scheme is clearly and completely described.
Referring to shown in Fig. 1 and 2, the online Fast active sampling valve of the embodiment of the present invention, including valve body 1 in the form of annular discs and be located at
Outer tunnel 3 and internal channel 4 are respectively equipped with the discoid rotary spool 2 of the top of valve body 1, the outward flange of valve body 1 and inward flange, and
Outer tunnel 3 and internal channel 4 are respectively provided with the sample holes 5 into sample in approximately the same plane on outer tunnel 3 and internal channel 4
With the stock layout hole 6 of stock layout product；Along being evenly provided with 16 quantitative loop injection ports 7 and 16 quantitative loops one week on valve body 1
Nesting port 8, quantitative loop injection port 7 is in the periphery of quantitative loop nesting port 8, and quantitative loop injection port 7 and quantitative loop nesting port 8 are one by one
Correspondence, is provided with the quantitative loop 9 for being used for collecting sample between one-to-one quantitative loop injection port 7 and quantitative loop nesting port 8；Rotation
On valve element 2 be respectively equipped with any one quantitative loop injection port 7 and a corresponding position of quantitative loop nesting port 8 exit orifice 10 and
Exit orifice 10 and endoporus 11 on endoporus 11, rotary spool 2 are connected with the outer tunnel 3 and internal channel 4 on valve body 1 respectively.
It is shown in Figure 3, when rotary spool 2 is rotated to exit orifice 10 and endoporus 11 and any one quantitative loop on valve body 1
Quantitative loop 9 during 8 pairs of correspondences of injection port 7 and quantitative loop nesting port on the position is connected with outer tunnel 3 and internal channel 4, quantitative
Ring 9 is sampled, and specific sampling process is：Sample enters from sample holes 5, sequentially passes through outer tunnel 3, exit orifice 10 and quantitative loop and enters
Sample mouthful 7, is entered in quantitative loop 9, and after sample collection in quantitative loop 9 is full, unnecessary sample passes through the row of quantitative loop nesting port 8
Go out, then sequentially pass through endoporus 11, internal channel 4, discharged from steam vent 6, now, the quantitative loop 9 completes sampling.
If desired sample next quantitative loop, rotary spool 2 continues to rotate, to making next He of quantitative loop injection port 7
Quantitative loop nesting port 8 is corresponding with exit orifice 10 and endoporus 11, now, and the quantitative loop 9 on the position is sampled；Repeat as above
The step, you can make all quantitative loops complete sampling.
It should be pointed out that embodiments of the invention are described above.However, art technology it is to be understood by the skilled artisans that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment, is not departing from this
