一种转子泵输送管路
摘要：
本发明公开了一种转子泵输送管路，包括：转子泵，转子泵的出口连接有出料管，转子泵的进口端设置有换向阀，换向阀第一阀口、换向阀上阀腔、换向阀第二阀口常通，换向阀开启状态下，换向阀上、下阀腔相互隔断，换向阀底部阀口打开，换向阀第三阀口通过换向阀下阀腔与换向阀底部阀口连通；换向阀关闭状态下，换向阀上、下阀腔相互连通，换向阀底部阀口被关断，换向阀第三阀口与换向阀上阀腔相连通；换向阀第三阀口上连接有进料管，换向阀第一阀口和换向阀底部阀口之间连接有带单向阀和离心泵的回流管，换向阀第二阀口与转子泵的进口相连通。本发明的优点在于：在实现高粘度的、或富含颗粒状果蔬的物料输送的前提下，能对洗涤液进行有效输送。
摘要（英）：

The invention discloses a rotor pump conveying pipeline. The rotor pump conveying pipeline comprises a rotor pump, wherein an outlet of the rotor pump is connected with a discharging pipe, and an inlet end of the rotor pump is provided with a reversing valve, a first valve port of the reversing valve, an upper valve cavity of the reversing valve and a second valve port of the reversing valve are normally opened; the reversing valve is in a open state, an upper valve cavity and a lower valve cavity of the reversing valve are separated from each other, a reversing valve bottom valve port is opened, and a third valve port of the reversing valve communicates with the reversing valve bottom valve port through a lower valve cavity of the reversing valve; the reversing valve is in a close state,the upper valve cavity and the lower valve cavity of the reversing valve communicates from each other, the reversing valve bottom valve port is closed, the third valve port of the reversing valve communicates with the upper valve cavity of the reversing valve, a feeding pipe is connected to the third valve port of the reversing valve, a backflow pipe with a one-way valve and a centrifugal pump isconnected between the first valve port of the reversing valve and the reversing valve bottom valve port, and the second valve port of the reversing valve communicates with the inlet of the rotor pump.The rotor pump conveying pipeline has the advantages that the washing liquid can be effectively conveyed on the premise that high-viscosity materials or materials rich in granular fruits and vegetables are conveyed.
