Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy for operation and do not affect the normal pressurized plugging-up device of producing of power plant.
For achieving the above object, the technical solution used in the present invention is:
A kind of pressurized plugging-up device, comprise guide tube, guide tube is the airtight shutoff valve that is communicated with of an end wherein, it is characterized in that: the airtight welding slips that is communicated with of the guide tube the other end, the welding slips is corresponding with medium pipeline, the welding slips is arc plate, have through hole on the welding slips, guide tube communicates with this through hole, the flexible seal groove of welding slips side opening around this through hole, be provided with elastic seal ring in the elastic packing groove, elastic seal ring and guide tube lay respectively at the both sides of welding slips, are fixedly connected with below hook on the guide tube side of welding slips place side; This pressurized plugging-up device also comprises auxiliary connecting plate, auxiliary connecting plate one side is fixedly connected with tightening nut, the tightening nut internal thread is connected with clamping bolt, also have through hole on auxiliary connecting plate, this through hole communicates with tightening nut, upper being fixedly connected with below of auxiliary connecting plate is fastenedly connected chain, and the free end that is fastenedly connected chain is corresponding with hook.
When using the present invention to carry out shutoff to the leakage point of medium pipeline, at first with polishing machine with the polishing of leakage point place, so that during welding, welding slips and medium pipeline are sturdy, then elastic seal ring is positioned in the elastic packing groove, to weld slips is buckled on medium pipeline, make the mouth of pipe of guide tube aim at leakage point, make the water of leakage or steam can pass through the guide tube drainage.Then securing means is fixed on the medium pipeline opposite side, screws clamping bolt, until welding slips place no longer includes medium and spills, the water of all leakages or steam are all by the fairlead drainage.To weld slip seals with electric welding be welded on outside medium pipeline this moment, weld and close shutoff valve with the guide tube shutoff after completing, and just no longer include water or steam spills, and maintenance is finished dealing with.
Adopt the urgency for the treatment of of Power operational outfit burst dielectric leakage of the present invention; can with pressurely carry out; do not affecting under the normal prerequisite of producing of power plant; to being with temperature, leakage equipment with pressure to carry out shutoff, reparation; the problems such as run, drip, leak of pipeline be can eliminate rapidly, unit load down that conventional repair method may cause, shutdown avoided and the tremendous economic loss that brings.
Compare with traditional leak stopping mode, adopt the present invention to have the following advantages:
1, simple to operate, with low content of technology, do not need special training, common service worker can operate.
2, maintenance cost is low, expense is few, has eliminated the time that system stops transport.
