上記片面と密接する摺動面に複数の流通路未満が開口し
ている本体とを、同一軸心にて回転自在に摺動してガス
流通路の切換えを行なうものにおいて、上記本体の摺動
面又は上記摺動板の片面に圧封入溝を穿設して取出孔と
連通し、上記本体と摺動板とが非サンプリング位置にあ
っては上記圧封入溝をどの流通路とも連通せずかつサン

クロマトグラフ装置用切換バルブ。A sliding plate with a plurality of communication grooves bored on one side and a main body having a plurality of flow passages opened on the sliding surface of the sliding plate that is in close contact with the one side of the sliding plate can be rotated about the same axis. In the device that switches the gas flow path by sliding, a pressure sealing groove is bored on the sliding surface of the main body or one side of the sliding plate to communicate with the extraction hole, and the main body and the sliding plate are connected to each other. A process gas chromatograph characterized in that when the pressure sealing groove is in a non-sampling position, the pressure sealing groove does not communicate with any flow passage, and when the pressure sealing groove is in a sampling position, the pressure sealing groove communicates with a flow passage for supplying carrier gas. Switching valve for equipment.
