Liquid transfer device in an installation, bituminous binder spreading apparatus with a transfer device and process for operating the spreader

转移设备(1)包括泵(9)，该泵具有借助安装板(3)被安装到储存罐(5)壁上的泵体。在泵体内和穿过安装板(3)的用于液体的通道开口容许液体在储存罐(5)与部件(6a，6b)(例如沥青撒布轨)和用于储存罐(5)的补充液罐(7)的至少一个之间的转移。控制阀门(21，22，23，24，25，26，27)各包括一个闸板，该闸板被安装以便在泵体内可移动，并且该闸板通过致动器作平移运动，容许控制液体的转移。本发明还特别涉及用于液体沥青粘合剂的撒布机。 The transfer system for a bituminous liquid from a storage tank (5) to one or more user components (6a, 6b) such as spray bars and a refill tank (7) consists of a pump with its body on a mounting plate fixed to an internal wall of the storage tank. The pump body has ports (11 - 18) that are opened and closed by control valves (21 - 27), each having a shutter (21a) that is moved in the pump body by a control element (21b) fixed to a mounting plate on the outside of the storage tank and made e.g. in the form of a pneumatic cylinder with its mobile component moving perpendicular to the mounting plate.
