Specific implementation method
Now a kind of sample valve is described in the mode more more detailed than above general introduction.
Yet, before describing the present invention in detail, need give statement, the present invention is not limited to for example concrete of the description of doing.Can make various variations to described the present invention and replace not deviating from aim of the present invention and scope with equivalent.Unless otherwise defined, in that these all used technology scientific and technical terms should to do common understanding identical with those of ordinary skill in the technical field of the invention.
Sample valve by a preferred embodiment of the present utility model has been shown among Fig. 1.
This sample valve, it can comprise a body apparatus 20.As shown in the figure, this body apparatus 20 has a body 201, and the cylindrical ends 2011 that extends to a sampling area is arranged on it.And so-called sampling area can be any suitable chemical industry facility, for example is reactor 10 (only schematically showing a part among the figure), can certainly be in the Chemical Manufacture flow process place's pipeline sampled point, or the like.
Body apparatus 20 also includes a back and forth sampling shuttle 202 in this body 201, and the driver 30 that sampling shuttle 202 is back and forth taken a sample by the demand execution, or 31.
On sampling shuttle 202, close on guide part 2022 places of front end, have a concave area 2021.Concave area 2021 can be to form a cylindric ring groove of making on the right cylinder that is slidingly matched with cylindrical ends 2011 inside surfaces.When sample valve be in the sampling ready position, promptly during as shown in Figure 1 position; The through hole 2012 of this concave area 2021 over against body end 2011 along the circumference place; And when sample valve be in the sampling executing location, promptly during as shown in Figure 2 position, sampling shuttle 202 is subjected to the back and forth driver 30 of sampling, or 31 driving is moved to outermost end.Sample tap 2013 on this moment this concave area 2021 and the body 201 just constitutes and communicates, like this by instantaneous acquiring to, the sampling material of transient response state can carry out assay by sample tap 2013 taking-ups in the sign flow process.And the front end guide part 2022 of the shuttle 202 of this moment taking a sample is owing to be a kind of being slidingly matched, it and cylindrical ends 2011 inside surfaces are radially almost very close to each other, and can close and inner passage, and then with, for example still in the possible high heat of high pressure (or differ from normality) reaction zone form and isolate.And the sampling shuttle is exactly according to demand, or according to the manipulation of predefined program by driver in sampling ready position and the reciprocating action between the executing location of taking a sample.
In addition, above-mentioned through hole 2012 can be diversified, and quantity also is not limited to single.For example just represented other a kind of form in Fig. 4, through hole 2012 can be a kind of to be circular-arc through hole with the slotting cutter side edge from what two side direction of cylindrical ends 2011 inwardly milled out.Similar with it, the shape of concave area 2021 also can be to make the ring groove that is circular-arc.
Be exactly after sample tap 2013, to be (figure does not show) that to be arranged to be connected in addition with the robotization experiment device.And the product stream in the reaction is realized online detection and chemical examination by corresponding facility, and by the running of a control system reaction conditions is done adaptive adjustment according to assay, and realize the automatic control of production procedure.For ease of the taking-up that is sampled, also can be equipped with gas hole of may command pressure or the like on the opposite of sample tap 2013.
Body apparatus 20 is with chemical production equipment, for example the junction of the sampling area of a reactor 10 also is provided with packoff 2014 (seeing Fig. 1 for details).Its effect is to form with reaction zone to isolate sealing.
30 of drivers can be a kind of screw devices.As an example, it can comprise a screw rod 301 that is connected to these sampling shuttle 201 rear ends, and is fixedly supported to a rotation nut 302 on the shell 306.At the screw device shown in this, also include rolling bearing 303, be connected to this rolling bearing 303 in ring go up and pass through a kind of rotation nut 302 that handwheel 305 rotates by what flat key 304 was connected.Obvious this configuration is not unique.Any suitable screw mechanism all is fine in the prior art.Such as, for simplicity, rotation nut 302 can be to be supported in (figure does not show) on the axial constrained axle sleeve type bearing.
As a kind of replacement scheme, driver can also be a kind of reciprocator 31 that is driven by cylinder body, as shown in Figure 3.And this set is particularly suitable for on-line automatic control model.It includes a piston rod 312 that is connected with shuttle 201 rear ends of taking a sample, and coupled piston 313; Piston 313 is contained within the cylinder cover 316.Cylinder cover 316 two ends have end cap 311,315 respectively.Dispose and control the pipe adapter 314 that the pipe system (figure do not show) of fluid is joined on the end cap 311,315.The fluid of control fluid piping system both can be a hydraulic pressure, also can be pneumatic.Control fluid drives sampling shuttle according to the preset program of design and carry out sampling, assay or the like.Promptly can be implemented in the automatic control of line as previously mentioned.
Sample valve of the present invention can be used in various suitable Chemical Manufacture equipments.For example can be but not only limit be reactor.
A kind of reactor 10, promptly as schematically showing in the accompanying drawing, its housing 101 is provided with sample valve.Sample valve has comprised a body 201, and body 201 has 2011, one a reciprocal sampling shuttle 202 and the drivers 30,31 that make this sampling shuttle 202 carry out back and forth to take a sample by demand in this body 201 in end that extend to sampling area.Closing on front end guide part 2022 on the sampling shuttle 202 has a concave area 2021, when being in the sampling ready position, and the through hole 2012 of this concave area 2021 over against body end along the circumference place; And communicate with a sample tap 2013 on the body 201 when sampling executing location time sampling shuttle is moved to outermost end, this moment this concave area, this front end guide part 2022 is then sealing the passage with inside.
Though the present invention is described with reference to the various characteristics with single example and selectable combination, the present invention is not limited to for example concrete of the description of doing.Self-evident, for the purpose that realizes invention, many modifications of narration being done for the adaptation actual conditions are included within the scope of these claims of doing.
