Abstract

The utility model discloses a mechanical type pipeline under-pressure fluid blocking tool and belongs to the technical field of blocking devices. The mechanical type pipeline under-pressure fluid blocking tool solves the problem that in the prior art, base clamping and base sealing can lose effect easily and blocking cannot be effectively achieved. Inner threads are formed in a connection base of the mechanical type pipeline under-pressure fluid blocking tool and form a spiral pair with outer threads in a draw bar, a clamping base is fixedly connected with the lower portion of the connection base, slip teeth penetrate the clamping base to be fixedly connected with the connection base, a conical angle of the outer conical surface of the outer portion of an upper base is larger than a conical angle on the inner conical surface arranged under the inside of the slip teeth, a base plate is fixedly connected with the draw bar, a lower base is in clearance fit with a rubber tube and the draw bar, and the connection base is connected with an outer transmission mechanism. The draw bar rotates to move upwards or downwards, so that the rubber tube is compressed or can recover to a normal state, and base clamping, base sealing, base unclamping and base unsealing can be achieved. Plane bearings are installed on the lower portions of the rubber tube and the slip teeth, and friction resistance caused by contact of all parts can be reduced. Blocking on pressure fluid in a pipeline can be achieved under any work condition in a mechanical mode, and the mechanical type pipeline under-pressure fluid blocking tool is simple in structure and safe and effective.
