摘要： A below grade, spill containment device for connection with the riser pipe of an underground fuel storage tank. The containment device is disposed within and isolated from a manhole, which is mounted in a concrete apron. The containment device comprises a compositely formed container, rigidly mounted on the riser pipe. The container formed of structural synthetic resin material elements held in assembled relation by snap fitted lugs and notches. A lid, for closing the upper, access opening, is mounted on a pivotable arm. A lever pivoted on the arm selectively engage latch means to lock the lid in a closed position. A projection on the lever prevents the manhole cover from seating if the lever is not in its lock position. A valve for draining fuel from the container to the riser pipe is closed when the lid is open and opened when the lid is closed. The manhole and the containment device are packaged in a shipping carton in spaced relation be corrugated paper sheets. These sheets are employed in obtaining a desired relation between the containment device and manhole in the installation of these components, which involve pouring a concrete apron around the upper end of the manhole. An alternative system employs adjusting nuts to obtain this relationship between the manhole and containment device. In one embodiment the manhole is compositely formed to permit relative movement between its upper and lower portions, after installation.
摘要翻译： 以下级别，与地下燃油储罐的提升管连接的泄漏容纳装置。 容纳装置设置在安装在混凝土围裙中的人孔内并与之隔离。 容纳装置包括刚性地安装在提升管上的复合形成的容器。 由结构合成树脂材料元件形成的容器通过卡扣配合的凸耳和凹口保持组装关系。 用于封闭上部进入开口的盖子安装在可枢转的臂上。 枢转在臂上的杠杆选择性地接合闩锁装置，以将盖锁定在关闭位置。 如果杠杆不在其锁定位置，则手柄上的突出部可以防止人孔盖座。 当盖子打开并且当盖子关闭时打开时，用于将燃料从容器排出到提升管道的阀门关闭。 人孔和遏制装置以分隔的形式包装在装运纸箱中，为瓦楞纸。 这些片材用于在安装这些部件时获得容纳装置和人孔之间的期望关系，这涉及将混凝土围裙倒入人孔的上端。 替代系统采用调节螺母来获得井下和密封装置之间的这种关系。 在一个实施例中，在安装之后，人孔被复合形成以允许其上部和下部之间的相对运动。

摘要： A swivel adapter for an inlet conduit to an underground storage includes two relatively rotatable components. The relative rotation between the components prevents sealing loss between the adapter and the inlet conduit when the adapter is subjected to torque.

摘要： A shield positioned on the exterior of a sump to provide an access space for displacement of a portion of an entry fitting into the access space. The shield can allow for the removal of the entry fitting or an entry fitting seal without having to first remove backfill from the exterior of the sump.

摘要： An entry fitting having a cylindrical portion and a conical portion including a seal disposed about the body of the entry fitting. An axial displacement member urges the seal along the conical portion to achieve a relatively wide range of sealing force. The entry fitting can include a shield positioned on the exterior of a sump to provide an access space for displacement of the entry fitting toward the exterior of the sump to allow removal and replacement of the seal without first having to remove backfill from the exterior of the sump.
