    • The present invention relates to chemical delivery systems and methods for delivery of liquid chemicals. In one embodiment, the present invention relates to systems having multi-reservoir load cell assemblies for delivering chemicals used in the semiconductor industry. In one embodiment, the present invention provides a multi-reservoir load cell assembly, including a controller, a buffer reservoir, a main reservoir, one or more load cells, coupled to the assembly and to the controller, operable to weigh the liquid in the reservoir(s), a plurality of supply lines, each supply line having a valve and connecting one of the supply containers to the main reservoir, and a gas and vacuum sources for withdrawing the liquid from the assembly when demanded by the controller and for refilling the assembly from the supply containers.
    • 本发明涉及用于输送液体化学品的化学物质输送系统和方法。 在一个实施例中,本发明涉及具有用于输送半导体工业中使用的化学品的多储存器称重传感器组件的系统。 在一个实施例中,本发明提供一种多储存器称重传感器组件,其包括控制器,缓冲储存器,主储存器,联接到组件和控制器的一个或多个称重传感器,可操作以称重 储存器,多个供应管线,每个供应管线具有阀并将供应容器中的一个连接到主储存器;以及气体和真空源,用于当由控制器要求并且用于重新填充时从组件中抽出液体 从供应容器组装。

    • In a preferred embodiment, a blow molded drum has a port including a neck with exterior buttress threads and a port opening having a shoulder. A snap-in down tube assembly seats with the shoulder and has an upwardly extending nipple. Either a dispense head or a closure seats within and is secured by a threaded retainer nut. The dispense head has a first flow duct extending to a nipple engaging portion to seal with the upwardly extending nipple and a second flow duct leading to an annular space around the nipple for a return fluid line or for providing air or a gas for displacing withdrawn fluid. In a preferred embodiment the threaded nut provides an axial tightening force and also provides an axial removal force that disengages the nipple engaging portion with the nipple as the retainer nut is loosened
    • 在优选实施例中,吹塑成型的滚筒具有包括具有外部支撑螺纹的颈部和具有肩部的端口开口的端口。 卡扣式下管组件与肩部座椅并具有向上延伸的接头。 分配头或封闭件可以安装在螺纹固定螺母内并由螺纹固定螺母固定。 分配头具有延伸到乳头接合部分以与向上延伸的接头密封的第一流动管道,以及通向乳头周围的环形空间的第二流动管道,用于返回流体管线或用于提供空气或用于移出排出流体的气体 。 在优选实施例中,螺纹螺母提供轴向紧固力并且还提供轴向移除力,其在保持螺母松动时使乳头接合部分与乳头脱离
