Abstract
The utility model provides a fixture are rushed to repair to light -duty fast -assembling of high pressure pipeline, these fixture of include the card body, lower calorie of body, rotation axis, clamp bolt, sealing unit, partial pressure drainage hole, rings, reinforcing ring and coarse pitch compression screw. The beneficial effect of the utility model: the utility model is suitable for a leaking stoppage operation is salvageed to the high strength pipeline of any bore, the less easy operation of equipment dead weight, the installation of being convenient for, seepage, crackle and any emergency appear on the long distance pipeline and under, can accomplish under the shortest condition and salvage the leaking stoppage task, back and pipeline welding are forever accomplished together to the task of salvageing, have solved the hidden danger of initiation that puncture vine accident. And the cost is reduced, the practicality is strong, easily popularizes and applies.
Description
Technical field
The utility model relates to a kind of first-aid clamp, particularly relates to a kind of high pressure pipe line Light-duty Quick-installation first-aid clamp.Be a kind of rapid rush-repair facility of Oil-gas Long-distance Transportation Pipeline, when there is the urgency such as crackle, leakage for long distance pipeline, carry out permanent or temporary pipeline leak stopping fast, pipeline strength rehabilitation.
Background technique
At present, domestic industry generally adopts common many screw clamps compact form long-distance transport pipes rapid rush-repair fixture, structure as shown in Figure 1, namely when conveyance conduit urgency with common many screw clamps compact form long-distance transport pipes rapid rush-repair fixture
1) stud linking number is more, and in the process of fastening nut, the connection of previously having tightened constantly gets loose again, causes the jig repairing operating time long, does not have the object of quick mounting repairing leak stopping.
2) jig material mechanical property is lower, overall blocked up, causes whole fixture structure heavy.
3) employing bar shaped mechanical seal can not play the sealing to high pressure pipe line leakage point, and the full Stamping Steel Ribbon that relies on seals, unreliable, does not have the effective leak stopping effect of long-term safety.
4) even if weld after installing, except hoop fillet welding and junction plane seal weld, stud, nut be necessary seal weld also, otherwise will leak from threaded connection place, and welding capacity is excessive.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of high pressure pipe line Light-duty Quick-installation first-aid clamp.
The utility model is achieved in that this jig comprises card, lower card, running shaft, hold-down bolt, sealing unit, dividing potential drop conduction hole, suspension ring, stiffening ring and large screw pitch clamping screw; Upper card and lower card are semicircular structure, upper card and lower card two ends are linked together by running shaft, hold-down bolt and large screw pitch clamping screw, upper card and lower card circumferential direction are all welded with stiffening ring, sealing unit is arranged on inside card and lower card, upper card and lower card outer wall are all provided with suspension ring, upper card are provided with dividing potential drop conduction hole.
Described sealing unit comprises O RunddichtringO, transverse sealing bar and heat insulation rope, O RunddichtringO is positioned on card and lower card annular inner wall, transverse sealing bar is arranged on the joint between card and lower card, outside O RunddichtringO and transverse sealing bar, be provided with heat insulation rope.
Described large screw pitch clamping screw inserts in running shaft, and is fixed by hold-down bolt.
The beneficial effects of the utility model:
The utility model is applicable to the high strength pipe repairing plugging operations of any bore, equipment self-weight is less simple to operate, be convenient to install, long distance pipeline occurs seepage, crackle and in emergency circumstances any, repairing leak stopping task can be completed in the shortest situation, forever weld together with pipeline after repairing task completes, solve the hidden danger causing your thatch accident.And reduce cost, practical, be easy to apply.
accompanying drawing illustrates:
Fig. 1 is the utility model using state schematic diagram;
Fig. 2 is the utility model structural representation;
In figure: card, 2 times cards, 3 running shafts, 4 hold-down bolts, 5 sealing units, 6 dividing potential drop conduction holes, 7 suspension ring, 8 stiffening rings, 9 large screw pitch clamping screws on 1.
Embodiment
Below in conjunction with accompanying drawing and enforcement, the utility model is further described.
In the present embodiment, upper card 1 and lower card 2 all adopt more than X70 pipeline high-grade alloy steel.
As illustrated in fig. 1 and 2, this jig is split structure, comprise card 1, lower card 2, running shaft 3, hold-down bolt 4, sealing unit 5, dividing potential drop conduction hole 6, suspension ring 7, stiffening ring 8 and large screw pitch clamping screw 9, described sealing unit 5 comprises O RunddichtringO, transverse sealing bar and heat insulation rope, upper card 1 and lower card 2 are semicircular structure, upper card 1 and lower card 2 two ends are by running shaft 3, hold-down bolt 4 and large screw pitch clamping screw 9 link together, large screw pitch clamping screw 9 inserts in running shaft 3, and fixed by hold-down bolt 4, upper card 1 and lower card 2 circumferential direction are all welded with stiffening ring 8, O RunddichtringO is positioned on card 1 and lower card 2 annular inner wall, transverse sealing bar is arranged on the joint between card 1 and lower card 2, heat insulation rope is provided with outside O RunddichtringO and transverse sealing bar, upper card 1 and lower card 2 outer wall are all provided with suspension ring 7, upper card 1 is provided with dividing potential drop conduction hole 6.Adopt large screw pitch hold-down bolt 9 to be fixed on high pressure line, utilize sealing unit 5 to be sealed by leakage point.Finally jig and pipeline welding are integrated.
Working procedure of the present utility model:
1. first dividing potential drop drainage tube is connected with dividing potential drop conduction hole 6;
2. adjust jig folding angle, lift four suspension ring 7 and jig is opened.
3. being sling by jig repairing high pressure long-distance transport pipes put down makes jig encircle long-distance transport pipes.
4. large screw pitch clamping screw 9 is arranged on upper and lower card.
5. lifting rotary fixture makes jig become horizontal dividing potential drop conduction hole 6 upward.
6. jig is lifted into repairing position.
7. utilize the tighter large screw pitch spanner of ratchet wrench to make jig compress long-distance transport pipes, effectively shutoff leak source.
8. finally upper and lower card and long-distance transport pipes are welded as a whole, complete repairing.
