Abstract

Sealing plug device with pneumatic controls for momentary closing of hollow bodies, especially hollow bodies, that must be subjected to a test operation, characterized by an elastically deformable lining against which the wall of a branch pipe is brought of a hollow body to be sealed, a piston displaceable against the action of a spring, which is attached to said lining and normally maintained by said spring in a position, for which the same seals an orifice for the arrival of fluid under pressure, being provided manual control means to move the piston against the action of the spring by a measure, by which it discovers said pressure fluid arrival hole, the fluid of which then causes a subsequent displacement of said piston, to deform said elastic seal, thus sealing the duct of the hollow body.
