シリンダを接続し、且上記コンクリートポンプ内
に開口を位置させた揺動管を該開口が２本の輸送
シリンダに交互に連通するよう揺動できるように
してあり、輸送シリンダに吸入されたコンクリー
トが揺動管内を圧送されて輸送されるようにして
あるコンクリートポンプにおける上記揺動管とし
て、内面に高周波焼入れを施こした直管同士を屈
曲した形状に溶接接合し、且つ該溶接接近傍のみ
硬化肉盛をしてなる揺動管を用いてなることを特
徴とするコンクリートポンプの流路切換弁。 Two transport cylinders are connected to the lower front surface of the concrete hopper, and a swing pipe having an opening located in the concrete pump is swingable so that the opening communicates alternately with the two transport cylinders. In a concrete pump, the concrete sucked into the transport cylinder is conveyed under pressure through the oscillating tube.The oscillating tube is formed by bending straight tubes with induction hardening on the inner surface. A flow path switching valve for a concrete pump, characterized in that it uses a swinging pipe which is welded together and hard-clad only in the vicinity of the weld.
