Detailed description of the invention

Below, in conjunction with accompanying drawing, the technical solution of the utility model is further described again:

As Figure 1-4, the missing inspection investigation cap that a kind of elemental analyser and solid automatic sampler on-line joining process use, containing solid automatic sampler 1 and elemental analyser 2, solid automatic sampler 1 includes the sample purge hole 7 on automatic sampler sliding bar 3, He gas-carrier pipeline 4, many positions in storehouse specimen disc 5, purge gas pipeline 6 and sliding bar；Elemental analyser 2 package includes elemental analyser export pipeline 8, reaction tube outlet nut 9, elemental analyser entrance nut 10, looks into cap gland 11, sample feeding hole 14, elemental analyser exit seal nut 15 and the detector 16 investigated on cap carrier gas mouth 12, investigation cap pressure pad nut 13, sliding bar.Connect by elemental analyser entrance nut 10 spiral on reaction tube is fixing between elemental analyser 2 and solid automatic sampler 1, in solid automatic sampler 1, purging gas is entered the space in the sample purge hole 7 purged on sample bag and sliding bar by purge gas pipeline 6, ensure space and the cleaning of sample bag, avoid outside air to be carried along into reaction tube, have air to enter during precession in order to avoid automatic sampler sliding bar 3 simultaneously.Driven by motor automatic sampler sliding bar 3 precession, automatic sampler sliding bar 3 precession driven gear rotates, and pinion rotation drives many positions in storehouse specimen disc 5 to rotate, automatic sampler sliding bar 3OnThe rubber seal of an opening is had respectively between sample purge hole 7 and the position, 14 two holes, sample feeding hole on sliding bar on sliding bar, ensure space and the cleaning of sample bag, outside air is avoided to be carried along into reaction tube, meanwhile, for avoiding the sample sliding bar 3 on sliding bar to have air to enter the sample feeding hole 14 on sliding bar during precession.Sample feeding hole 14 on sliding bar connects with He gas-carrier pipeline 4；Enter on elemental analyser outlet reaction pipeline 8 at solid automatic sampler 1, investigation cap gland 11 and missing inspection are quickly investigated cap pressure pad nut 13 and are connected, He gas-carrier pipeline 4 on solid automatic sampler 1 is tightly connected with investigation cap carrier gas mouth 12, on elemental analyser export pipeline 8, reaction tube outlet nut 9 and elemental analyser exit seal nut 15 coordinate spiral to connect, elemental analyser export pipeline 8 connects elemental analyser 2 and detector 16, is the passage of the gas entrance detector generated after reaction is carried in He carrier gas.

nullWhen elemental analyser 2 and solid automatic sampler 1 state of leaking air cannot judge air leakage point，Missing inspection is used quickly to investigate cap: to unclamp elemental analyser entrance nut 10，Disconnect solid automatic sampler 1 and the connection of elemental analyser 2，Investigation cap gland 11 and missing inspection are quickly investigated cap pressure pad nut 13 connect，Then missing inspection is quickly investigated cap pressure pad nut 13 and the fixing connection of elemental analyser 2 spiral，He gas-carrier pipeline 4 on elemental analyser is tightly connected with investigation cap carrier gas mouth 12 simultaneously，At this moment He carrier gas enters elemental analyser 2 by pipeline gas-carrier pipeline 4，Three-way cock before being then shut off on connection element analyser entrance He air pipe 4 and connection element analyser export pipeline three-way cock below，Observe the He atmospheric pressure scale number on elemental analyser 2，If the gauge outfit number of degrees decline quickly in ten minutes，Show that reaction tube outlet nut 9 and the elemental analyser exit seal nut 15 of elemental analyser are problematic，Spiral is needed again to connect，Can also suds or argon detection observation，If this is intact the most problematic at two，Illustrate that reaction tube has to split，Reaction tube must be changed.Otherwise, the He atmospheric pressure scale number on elemental analyser 2 is constant, shows that the reaction tube of elemental analyser exports connection and reaction tube at nut 9 and 15 liang of elemental analyser exit seal nut the most intact；If elemental analyser does not has leak source, illustrate that air leak position is from solid automatic sampler 1, at this moment need to take the baffle plate before solid automatic sampler 1 apart, take out automatic sampler sliding bar 3, the rubber seal of three openings between position, 14 two holes, sample feeding hole above and on sliding bar, the sample purge hole 7 checked on automatic sampler sliding bar 3 on sliding bar, (these materials are often the sample bag bonding and residual when crushing to remove sample remnant in rubber seal, as infrequently cleared up, sticky object can scratch automatic sampler automatic sampler sliding bar, sliding bar has cut can affect sealing), if finding, rubber seal has abrasion omission, also need to the rubber seal more renewed.Such process, it is possible to be rapidly completed the quick investigation of leak source during elemental analyser uses, while providing conveniently for instrument operator, save time and testing cost.
