Description
Technical field
The utility model relates to the warehousing and transportation facilities technical field of petroleum and chemical industry industry, particularly the online first-aid clamp of a kind of oil and gas pipes.
Background technique
The oil and gas pipes of current China on-line operation has tens0000 kilometers, and wherein the length of service of some oil and gas pipes has reached more than ten years or twenties years.Owing to being corroded, the reason such as destruction, the situation such as small leakage, seepage causing oil and gas pipes local happens occasionally, and therefore makes the application of first-aid clamp become more and more extensive.
Existing oil and gas pipes first-aid clamp is mainly opposite opened structure, comprises upper shell and lower shell body two-part, utilizes bolted pretightening force, controlled in Seal cage by leakage point by hoop, longitudinal sealing.In use, this kind of structure relies on bolt pretightening to extrude single Stamping Steel Ribbon and realizes sealing, after jig installs, need to carry out online soldering to jig otic placode place, jig and tube contacts hoop place and bolt joint, to prevent when Stamping Steel Ribbon lost efficacy, ensure that oil gas does not leak.But this kind of jig forms the structural type that small size leaks, large size is stressed, and overall greatly stressed, the thickness of jig itself and Bolt sizes are all larger; Simultaneously; in wire bonding, there is higher danger; also pipeline body may be caused owing to welding the damage caused; and weld job is subject to the impact that fixture structure cannot reserve the objective factors such as bevel for welding, detection mode be limited; weldquality is made to be difficult to ensure; often there will be the generation of postwelding crackle, cause new potential safety hazard.
Model utility content
Large in order to solve existing oil and gas pipes first-aid clamp lifting surface area, in problems such as wire bonding danger are large, the utility model provides the online first-aid clamp of a kind of oil and gas pipes, and described jig comprises upper shell, lower shell body, nut, bolt, transverse sealing bar, hoop Stamping Steel Ribbon, injecting glue observation vent and hole for injecting glue; Described upper shell and lower shell body are fastenedly connected by described nuts and bolt; Described upper shell and lower shell body inside are provided with groove, and described transverse sealing bar and hoop Stamping Steel Ribbon are arranged in described groove, and described transverse sealing bar and the multiple independently sealed chamber of the interlaced formation of hoop Stamping Steel Ribbon; Each sealed chamber is provided with described injecting glue and observes vent and hole for injecting glue.
Described hole for injecting glue has internal thread; Described hole for injecting glue is connected with glue filling device by described internal thread.
Described injecting glue is observed vent and is provided with internal thread.
The online first-aid clamp of the oil and gas pipes that the utility model provides, adopt the glue injection structure of multiple sealed chamber, each sealed chamber is independent sealed, leakage point is enclosed in the sealed chamber at center, and injecting glue process is adopted to sealed chamber, leakage point is effectively controlled, enhance first-aid clamp and sealing effect is installed, thus decrease the lifting surface area of first-aid clamp, eliminate the danger in wire bonding, improve the high efficiency of first-aid clamp online assignment, safety reliability.

Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further described.
See Fig. 1 and Fig. 2, the utility model embodiment provides the online first-aid clamp of a kind of oil and gas pipes, comprising: upper shell 1, lower shell body 2, nut 3, bolt 4, transverse sealing bar 5, hoop Stamping Steel Ribbon 6, injecting glue observe vent 7 and hole for injecting glue 8.Wherein, upper shell 1 and lower shell body 2 are fastenedly connected by nut 3 and bolt 4; Upper shell 1 and lower shell body 2 inside are provided with groove (not shown), and transverse sealing bar 5 and hoop Stamping Steel Ribbon 6 are arranged in groove, and transverse sealing bar 5 and the multiple independently sealed chamber of the interlaced formation of hoop Stamping Steel Ribbon 6; Each sealed chamber is provided with injecting glue and observes vent 7 and hole for injecting glue 8.
In actual applications, the material of upper shell and lower shell body is Q345R or 16Mn III forging; The material of nut is 30CrMo; The material of bolt is 35CrMoA; The material of transverse sealing bar and hoop Stamping Steel Ribbon is nitrile rubber; As shown in Figure 3, injecting glue is observed vent and is had internal thread, after injecting glue terminates, adopts bolt tightening sealing; As shown in Figure 4, hole for injecting glue has internal thread, and hole for injecting glue is connected with glue filling device by internal thread; After injecting glue terminates, adopt bolt tightening sealing.
When oil and gas pipes occurs leak or have a crackle, on the leakage point that the first-aid clamp of the utility model embodiment is arranged on oil and gas pipes or crackle, and leakage point or crackle is made to be positioned at the sealed chamber at center; Injecting glue process is carried out to the sealed chamber around the sealed chamber of center, after treating environmental seal chamber injecting glue, the injecting glue of all sealed chamber observation vent and hole for injecting glue is shut by bolt, completes plugging operations.
The online first-aid clamp of the oil and gas pipes that the utility model embodiment provides, adopt the glue injection structure of multiple sealed chamber, each sealed chamber is independent sealed, leakage point is enclosed in the sealed chamber at center, form a little on-line pressure sealant space, its stressed space formed in this space reduces relative to overall jig lifting surface area like this, and its lifting surface area obviously reduces; Injecting glue process is adopted to sealed chamber simultaneously, when sealed chamber's trace at center is revealed, the sealing range that its peripheral seal chamber is formed fully can meet seal request, leakage point is effectively controlled, enhance first-aid clamp and sealing effect is installed, eliminate the danger in wire bonding, improve the high efficiency of first-aid clamp online assignment, safety reliability.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
