发明名称 Gate valve lid
摘要 An improved gate valve lid for covering an access tube of a service box assembly leading to a gate valve below street level. The lid has a vertical height which is greater than its diameter so that the lid may not be flipped out of the service box assembly. In one embodiment, the lid includes a two-part assembly having an upper portion which is sized to rest in a tapered upper section of the service box located near street level, and a lower portion which may be displaced laterally with respect to the upper portion to allow the lower portion to be centered within a lower section of the service box, which may be out of alignment with the upper section. In this embodiment, the lower adjustable portion of the gate valve lid is preferably a tubular element slidably located on a cross pin passing through holes located at the upper end of the element across a downwardly opening recess in the upper portion. In one embodiment, the lower portion of the lid is defined by a plurality of downwardly depending fingers.
