Sealing element 17 is the cylinder of polytetrafluoroethylene (PTFE) material, and the upper-end inner diameter of sealing element 17 is greater than end internal diameter, in sealing element 17 upper ends form sealing element interconnecting piece 1701, the sealing for the taper that the lower end of sealing element 17 reduces between outer diameter from top to bottom 1702, the diameter of 1702 lower end of sealing is less than the diameter of 18 bottleneck of sampling bottle, and the diameter of 1702 upper end of sealing is greater than sampling The diameter of 18 bottlenecks of bottle, it is good with the bottle sealing effect of sampling bottle 18 to guarantee, and can adapt to taking in different bores Sealing when sample bottle 18 samples, the leakage of dielectric gas when preventing from sampling effectively improve gas sampled to sampling personnel's body Pollution of the influence and gas sampled of body health to surrounding air.

Purging module 6 601 lower end of pipe connection portion protrude into sealing element interconnecting piece 1701, and with sealing element interconnecting piece 1701 are tightly connected, and the bottleneck of sampling bottle 18 is protruded into the lower part of sealing 1702, so as to the bottle sealing with sampling bottle 18 Connection.

As shown in Figure 10: sampling bottle mounting rack includes upper protective cover 19, lower protective cover 20 and pedestal 22, upper protective cover 19 The diameter of upper end is less than the diameter of lower end, and the middle part of upper protective cover 19 is the arc that from top to bottom diameter is gradually increased.Upper guarantor The internal diameter of 19 lower part of shield is greater than the outer diameter of 18 lower part of sampling bottle, and the internal diameter on upper 19 top of protective cover is greater than 18 top of sampling bottle Outer diameter and the outer diameter for being less than 18 lower part of sampling bottle.Lower protective cover 20 is the cylinder of lower end closed, and the internal diameter of lower protective cover 20 is greater than The outer diameter of upper 19 lower part of protective cover, the lower end of upper protective cover 19 are protruded into lower protective cover 20 and by articulated shaft 23 and lower protective cover 20 rotation connections.Pedestal 22 includes the disk of the column and column at middle part or more two sides, the closed end setting of lower protective cover 20 There is mounting hole, is slidably arranged in mounting hole in the middle part of column, disk on the upside of column and between the closed end of lower protective cover 20 It is provided with spring 21, so as to make the sampling bottle 18 on the disk being placed on the upside of column compress sealing element 17.

The upper end of upper protective cover 19 is provided with holding portion 1901, and the diameter in holding portion 1901 is equal to or slightly less than sealing element 17 The outer diameter on top, the inner wall in holding portion 1901 are arranged at intervals with multiple annular grooves.

The sampler is mainly used for the sampling of liquid medium, and application method is as follows, rotates upper protective cover 19 first, and will Sampling bottle 18 is placed on the disk on the upside of column, and upper protective cover 19 is then passed through 1901 clamping of holding portion with sealing element 17. Liquid medium forms circulation by input channel 102 and return flow line 103.

When needing to sample, input sampling valve 5 is opened, and by the input terminal of purge passage 603 and empty the defeated of channel 605 Outlet closing, sampling channel 602 of the liquid medium by purging module 6 enter in sampling bottle 18.

After the completion of sampling, input sampling valve 5 is closed, nitrogen is passed through into purge passage 603 by purge passage docking section, Nitrogen enters valve interconnecting piece 604 by purge passage 603 and inputs in the cavity between 5 spool of sampling valve, then leads to again Over sampling channel 602 enters in the cavity on 18 top of sampling bottle, is then blown out again by emptying channel 605, by adsorption tanks It is discharged after 14 absorption, completes sampling operation, avoided in sampling bottle 18 or there are liquid mediums in pipeline.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real Matter any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the guarantor of technical solutions of the utility model Protect range.
