座体と、該弁座体間に嵌入して滑合する平行な面
と本体の流路と同心の貫通孔を有すく板状の弁体
とを備え、上記弁座体が上記弁体の滑合面に対し
垂直方向に滑動するようにした仕切弁において、
流路の上流側の本体の内周側の端面と下流側弁座
体の内周側の端面とに、流路の上流側から下流側
に向かつて、流路の上流側弁座体の内周面と下流
側の本体の内周面の一部を覆う突起を流路と平行
に設けたことを特徴とする仕切弁。 Two valve seat bodies are provided around the flow path of the main body and have surfaces perpendicular to the flow path that are parallel and opposite to each other, and a parallel surface that fits and slides between the valve seat bodies and the main body. A gate valve comprising a plate-shaped valve body having a through hole concentric with a flow path, the valve seat body sliding in a direction perpendicular to a sliding surface of the valve body,
The inner end face of the main body on the upstream side of the flow path and the inner end face of the downstream side valve seat body are provided with an inner side of the valve seat body on the upstream side of the flow path from the upstream side of the flow path toward the downstream side. A gate valve characterized in that a protrusion is provided in parallel with a flow path to cover the peripheral surface and a part of the inner peripheral surface of the main body on the downstream side.
