The first valve rod 114 penetrates gear case 13 wall portions and the first driven wheel of differential 15 is connected and fixed, and the second valve rod 124 penetrates gear case 13 wall portions and the second driven wheel of differential 16 is fixed by mode one-body molded or that internal and external threads screws;
The first interface 111 of the first T-valve 11, the second interface 112, the 3rd interface 113 connect respectively nitrogen pipeline 42, fluid reservoir 3, sample export pipeline 43; The 4th interface 121 of the second T-valve 12, the 5th interface 122, the 6th interface 123 connect respectively described sample inlet pipeline 41, fluid reservoir 3, sampling line 44.One end that sampling line 44 is not connected with the second T-valve 12 is connected with sampling jar 6; Between entrance to the first T-valve 11 of nitrogen pipeline 42, be also provided with successively pressure regulator valve 421 and non-return valve 422.Above-mentioned connected mode all can internal and external threads screw connection.It should be noted that fluid reservoir 3 is connected between the first T-valve 11 and the second T-valve 12.
One end that sampling line 44 is not connected with the second T-valve 12 is connected with sampling needle 51 by one-body molded or tube socket or the internal and external threads mode such as spin; Sampling jar 6 bottleneck envelopes have barrier film pad 71.Barrier film pad 71 is composited by teflon and silica gel.One end that sampling line 44 connects sampling needle 51 is fixedly connected with fixed mount 6, and the connected mode here can be one-body molded, can be also the connection that screws of internal and external threads.Fixed mount 6 is comprised of sheath 61 and clasp 62, and the top of sheath 61 is fixedly connected with sampling line 44, and the lower end of sheath 61 is flexibly connected with clasp 62, removably connects.That mentions here removably connects, and refers to that clasp 62 can be fixing by bolt or bearing pin etc. and sheath 61 realizations more easily.One end of sampling needle 51 is connected with sampling line 44, and the other end, through the connecting portion of sampling line 44 and sampling needle 51, is placed in fixed mount 6.
Under conventional state, the first T-valve 11 and the second T-valve 12 are in the state shown in Fig. 8.Now, the first interface 111 of the first T-valve 11 and the second interface 112 and the 3rd interface 113 are not all communicated with each other; The 4th interface 121 of the second T-valve 12 and the 5th interface 122 and the 6th interface 123 are not communicated with each other.Therefore, sample inlet pipeline 41, sample export pipeline 43, nitrogen pipeline 42, fluid reservoir 3 and sampling line 44 are not all communicated with each other.
As shown in Figure 3, while using the enclosed sampling device collected specimens of the utility model description, change new barrier film pad 71 first to sampling jar 6; Unload clasp 62, sampling jar 6 is put into fixed mount 6 from the lower end of lower jacket 61, and firmly the connection of sampling line 44 and sampling jar 6, to sampling needle 51, until sampling needle 51 punctures barrier film pad 71, is realized in top; Clasp 62 is fixed on sheath 61, realizes fixing sampling jar 6.
As shown in Figure 4, after completing above-mentioned preliminary work, rotating operation bar 19, by the transmission of drive bevel gear 14, drive the first cone follower gear 15 and the second driven wheel of differential 16 to rotate, and then the position of the first T-valve 11 and the second T-valve 12 inner spools is adjusted to state shown in Fig. 9.Now, only the second interface 112 and the 3rd interface 113 connections in the first T-valve 11, first interface 111 is by spool shutoff; Only the 4th interface 121 and the 5th interface 122 connections in the second T-valve 12, the 6th interface 123 is by spool shutoff.Therefore, sample enters from sample inlet pipeline 41, through fluid reservoir 3, flows to sample export pipeline 43.In this process, allow liquid continuous stream through fluid reservoir 3, and postpone a period of time, to guarantee to get representative sample.
As shown in Figure 5, until fluid reservoir 3, be full of after sample, rotary manipulation bar 19, by the transmission of drive bevel gear 14, drive the first cone follower gear 15 and the second driven wheel of differential 16 to rotate, and then the position of the first T-valve 11 and the second T-valve 12 inner spools is adjusted to the state shown in Figure 10.Now, only first interface 111 and the second interface 112 connections in the first T-valve 11, the 3rd interface 113 is by spool shutoff; Only the 5th interface 122 and the 6th interface 123 connections in the second T-valve 12, the 4th interface is by spool shutoff.Therefore, sample export pipeline 43 disconnects and being communicated with fluid reservoir 3, and nitrogen pipeline 42 is communicated with fluid reservoir 3 by the first T-valve 11; Liquid in fluid reservoir 3 enters sampling jar 6 under the promotion of nitrogen, until all samples enters sampling jar 6, and sampler is removed.In this process, can according to actual conditions, regulate the pressure of nitrogen, guarantee carrying out smoothly of sampling.
As shown in Figure 6, after sampling, unload clasp 62, sampling jar 6 is pulled up from sampling needle 51.
In this process, consider that sealing in the sampling jar 6 that has barrier film pad 71 is an airtight space, when sample is when sampling needle 51 splashes into sample thief, air pressure in bottle can hinder splashing into of sample, and then the process of impact sampling, can use the saturating barrier film pad 71 of evacuation needle 52 thorn, the air of sampling jar 6 is discharged outside bottle by evacuation needle 52, guarantee carrying out smoothly of sampling.
Meanwhile, in order to be clear that the variation of liquid level in sampling process, prevent that sample from overflowing contaminated environment, sampling jar 6 is made into transparent vial.In order to make sampling jar 6 reduce the risk of explosion, at sampling jar 6 outer walls, post blow-out disc.
In addition, for handled easily personnel operation, in the outside of gear case 13, by modes such as bolt, bonding or fixings, be fixed with guidance panel 17, the opposing one side of guidance panel 17 and gear case 13 is fixed with state direction board 18 by modes such as bolt, bonding or fixings, and control lever 19 is through guidance panel 17 and state direction board 18.The one end that is exposed at gear case 13 outsides at control lever 19 is fixed with operating grip 10 by welding, the mode such as one-body molded, can drive the rotation of control lever 19 when rotating operation handle 10.As shown in figure 11, under normal conditions, the index line of operating grip 10 points to A point; During to the interior conveying sample of fluid reservoir 3, rotating operation handle 10 to B points; While carrying sample from fluid reservoir 3 is interior to sampling jar 7, rotating operation handle 10 to C points.So, operating personnel, in the process of whole sampling, only need go to relevant position by operating grip 10 by step, can complete whole operation.Whole process is convenient, fast, safety, needn't spend large cost training special messenger to sample, and has also greatly improved sampling efficiency on cost-saving basis.
Embodiment 2:
As shown in Figure 2, when collected sample, during high-temp liquid, need on the basis of embodiment 1, increase refrigeratory 8, this refrigeratory 8 is arranged on sample inlet pipeline 41.When high temp samples enters before fluid reservoir 3 through the second T-valve 12, need elder generation is cooling through subcooler.
More than statement is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, within these also should be considered as protection domain of the present utility model.
