摘要： 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duct leading to an annular space around the nipple for a return fluid line or for providing air or a gas for displacing withdrawn fluid.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
摘要翻译：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

摘要： A fluid dispensing system for use with a drum with a bung, and a drum insert that includes a downtube that inserts into the bung. A dispense head has provision for a return flow line that discharges recirculated fluid into the annular space around the drum insert downtube. A foaming reduction device minimizes foam created from the recirculation. The invention includes a spring-loaded poppet that closes when the dispense head is removed from the bung opening. The poppet is configured such that the engagement member is a ring shaped with support members extending axially. The engagement member seats on and couples with a nipple on the drum insert. The nipple has a seating portion to engage the engagement member of the poppet The invention also includes a seal verification conduit in fluid communication with a space intermediate two seals at a junction between the dispense head and the drum insert.
摘要翻译：一种用于与鼓一起使用的流体分配系统，以及包括插入到所述塞子中的下管的滚筒插入件。分配头具有用于将再循环流体排放到滚筒插入件下管周围的环形空间中的回流管线。减泡装置使从再循环产生的泡沫最小化。本发明包括一个弹簧加载的提升阀，当提升头从开口开口移开时关闭。提升阀构造成使得接合构件是具有轴向延伸的支撑构件的环形。接合构件位于滚筒插入件上并与其连接。该乳头具有与该提升阀的接合构件相接合的座部。本发明还包括密封验证导管，其与位于分配头和滚筒插入件之间的连接处的两个密封件之间的空间流体连通。
