The utility model relates to a smooth surface tube head pressure testing shutoff is with bloated stopper appurtenance, including double-end pull rod 1, one section bar footpath that is greater than another section bar footpath of double-end pull rod 1 has seted up pipe thread 6 at the terminal surface outside the one end of the small double-end pull rod of bar footpath, installs fastening nut 4 on pipe thread 6, and the lateral wall cover at double-end pull rod 1 is equipped with bloated cover 2, and the pot head that is big in the bar footpath is equipped with smooth surface tube head 7.
And a pressing sleeve 3 is fixedly arranged on the outer side of the expansion sleeve 2.
The outer terminal surface of one end at double-end pull rod 1 has been seted up pipe thread 6, installs fastening nut 4 on pipe thread 6, is equipped with the cover 2 that expands at the lateral wall cover of double-end pull rod 1, and the cover 2 outside fixed mounting that expands has pressure cover 3, and in use inserts the one end that 1 pole footpath is big of double-end pull rod into plain noodles tube head, then uses spanner fastening nut 4, and the cover 3 is pressed in the extrusion, presses the cover 3 extrusion cover 2 that expands, and the cover 2 that expands is extruded deformation, realizes the bloated tight shutoff of tube head.
A central hole 5 is formed in the double-head pull rod 1.
In order to enable fluid media to pass through, a central hole 5 is drilled in the center of the double-end pull rod 1, and the fluid media can be connected and led on pipe threads 6 at the end of the double-end pull rod 1, so that convenience is provided for conveying the fluid media in a pipeline or plugging and pressure testing.
The utility model has the advantages that:
1) When the double-head pull rod is used, one end of the double-head pull rod 1 with the large rod diameter is inserted into the plain tube head, then the nut 4 is fastened by using a wrench, the pressing sleeve 3 is extruded, the pressing sleeve 3 extrudes the expansion sleeve 2, the expansion sleeve 2 is extruded and deformed, and the tube head is expanded and sealed;
2) In order to enable fluid media to pass through, a central hole 5 is drilled in the center of the double-end pull rod 1, and the fluid media can be connected and guided on pipe threads 6 at the end of the double-end pull rod 1, so that convenience is provided for conveying the fluid media in a pipeline or plugging pressure test;
3) The tension force is large, the bearing capacity is strong, and the like, the cable is not easy to be separated after being installed in place, and the use is safe and reliable. And because of the dismouting is simple, can reduce intensity of labour, improve the operating efficiency, the device can improve the work efficiency of pipeline construction welding bead back ventilation protection, welded joint pipeline or equipment pressure testing well.
