<p>PURPOSE: To facilitate sample material take-out operation without being leaked by providing a device with an injection valve which is capable of ejecting a reaction component or the like to a reaction vessel and taking the sample out of the reaction vessel. CONSTITUTION: A liq. is ejected into the reactor 2 through an inlet or a connecting hole 34, an annular groove, a groove and a valve seat 30 in a spindle 21. The pressure required therefor is generated with an injection pump 7. The ejected liq. can be cooled or heated with a temp. regulator. The injection valve 10 is capable of alternately ejecting and taking the sample material out of the reactor 2. These two functions are surely selected with a seal which is adjustable by means of a fastening sleeve 18. The sample flowing within the connecting hole 34 through a connecting pipe 26 in the direction opposite to the ejecting direction is introduced from a pipe 6 to a valve 9, and is taken out through a heatable branch pipe 8. The pipe 6 is connectable to the connecting hole 34 via a quick joint.</p> |
