| 【課題】コンクリートポンプ用分配弁、コンクリートポンプ及びその制御方法、ならびにコンクリートポンプ車を提供する。
【解決手段】該コンクリートポンプ用分配弁は、後端がホッパーの流出口と連通されホッパーと搬送シリンダを連通する第１の原料吸込管と、後端がコンクリートポンプの転送管に回転可能と連通され搬送シリンダと転送管を連通する第１の圧送管と、を含むバルブを含み、バルブは駆動機構の駆動で２つの状態の間で変換でき、第１状態である場合、搬送シリンダが第１の原料吸込管を介してセメントスラリーを吸込み、第２状態である場合、搬送シリンダが第１の圧送管を介してセメントスラリーを圧送する。 当該構造の分配弁によると、コンクリートポンプがセメントスラリーの自然流動機能を充分に利用し、コンクリートポンプの原料吸込性能を向上でき、且つ、分配弁が高い耐圧力を有し、搬送シリンダを介してセメントスラリーが大きい圧力を有し、セメントスラリーの高圧圧送の需要を満たすことができる。 【選択図】図３ |
