Flow restrictor for installation in an underground conduit connected to an underground vault
A flow restrictor for installation in a connection having a terminus opening into an underground vault. The flow restrictor includes an annular restriction device and a concentration member. The annular restriction device is configured to be installed in the annulus near the terminus opening and to restrict a flow of one or more gases through the annulus of the connection. The concentration member is configured to concentrate the flow and includes a through-channel configured to allow the concentrated flow to flow between the underground vault and the annulus.
