Embodiment
Below in conjunction with description of drawings embodiment of the present utility model
As shown in Figure 1, the utility model makes up airtight sampling thief external structure and comprises handle 1, lock 2, through hole 3, detecting device 4, casing 5, electrostatic prevention joint 6, purge hole 7.Casing 5 is riveted joint or welding, casing 5 tops have through hole 3, through hole 3 can be made Any shape, can be one or more, detecting device 4 also is equipped with on casing 5 tops, detecting device 4 can be the poisonous medium detecting device, also can be the combustible medium detecting device, detecting device 4 be connected with Central Control Room DCS system by electric signal, just can show with the DCS system by detecting device 4 when dielectric leakage, remind the operator to take measures, fall into the main valve that makes up airtight sampling thief such as the pass, purge to purge hole 7, poisonous or combustible medium are driven away with steam or nitrogen, thereby assurance safety is equipped with handle 1 and lock 2 on the door of casing 5.Casing 5, handle 1 and lock 2 materials that the time do not produce spark for friction and make, casing 5 bottoms are provided with electrostatic prevention joint 6, can effectively prevent static.
As shown in Figure 2, the utility model makes up airtight sampling thief to be adopted medium is that the inner structure of gas phase or liquid phase comprises medium inlet 8, filtrator 9, reduction valve 10, refrigeratory 11, goes into bypass valve 12 before the steel cylinder, the inlet/ outlet valve 13 and 14 of steel cylinder 14, branch line 16, blowdown system 17.Being sampled medium is that a plurality of (only drawing three among the figure) can be liquid mediums according to the production actual conditions, also can be gas medium, can also be one or both the combination in them.Refrigeratory 11 is the multiple media that are sampled, the common cooler that enters successively, medium temperature is lower than 60 ℃ can be without refrigeratory 11, the medium of refrigeratory can be water, liquefied ammonia, cold oil etc., in reduction valve 10 back safety valve is housed, open jumping when the pressure superelevation, the inlet/outlet of steel cylinder 14 can be used screwed connection, also can connect with metal or flexible nonmetallic tubing.
The sampling process of the airtight sampling thief of combination as shown in Figure 2 is as follows: medium filters out impurity through filtrator 9 by arrival line 8, again to the reduction valve 10 suitable pressure that reduces pressure.The medium that temperature is high enters refrigeratory 11 makes the temperature of medium less than below 60 ℃, cooled medium removes the residual medium of blowdown system 17 bleeder lines through bypass valve 12 by branch line 16, treat that fresh medium guides to sampled point, then opened steel cylinder 14 inlet/ outlet valves 13 and 15 flushing steel cylinders 14 several minutes, make scouring media go blowdown system 17 to form and be sampled the airtight discharging of medium by valve 15, collected specimens in steel cylinder 14 is finished airtight sampling process then.
