Abstract:
1. A pipe clamp, comprising: a resiliently deformable cylindrical sealing sleeve having a continuous side wall with a slotted opening extending 180 degrees around the circumference of the side wall to receive a gate valve plate, the slotted opening being bordered by clamping wedges which extend radially outwardly from the sealing sleeve and terminate in protruding lips, the lips being resiliently movable between an open position for receiving the gate valve and a closed position pursed together to form a fluid tight seal or pressed against the gate valve to form a fluid tight seal; means for clamping the sealing sleeve to a pipe; pressure members on opposed sides of the slotted opening that overlie the clamping wedges; and means for exerting a clamping force upon the pressure members to force the clamping wedges toward each other thereby urging the lips into the closed position, the lips resiliently returning to the open position when the pressure upon the clamping wedges is released.
