Abstract
The utility model discloses a pressure-relieving and drainage type sealing fixture, comprising a cylindrical fixture body which is formed by butting two semi-circular arc slabs, wherein the butting edge of the fixture body is set as a folding edge, ring-shaped glue injection grooves are arranged at the inner sides of two ends of the fixture body respectively, a metal sealing ring is arranged at the inner side of each glue injection groove, the fixture body between the two metal sealing rings is provided with a drainage hole, and the drainage hole is communicated with a drainage pipe. According to the pressure-relieving and drainage type sealing fixture, through sealing a pipeline at a leaked part, the metal sealing rings at the two ends and gel inside the glue injection grooves can be used for packaging the leaked part; and the drainage hole is used for drainage, and thus the pressure inside the pipeline is relieved.
Description
Technical field
The utility model relates to the seal for pipe joints technical field, the jig of pressure release drainage type sealing specifically.
Background technique
Continuous development along with modernized oilfield construction, various petroleum pipelines are on the increase, but along with the continuous growth of life time, pipeline corrosion, the pipeline thorn that reasons such as quality cause leaks, fracture often occurs, traditional solution is exactly to stop production comprehensively, and welding leaks outside, and is not only time-consuming but also take a lot of work, and in the oil field gathering and transportation zone, get angry, have major accident hidden danger.If the corrosion leakage position is not protected, cause external pressure that corrosion place is beaten easily and come off, cause bigger leakage, perhaps sealer is squeezed into pipeline inside, can't play seal action.
The model utility content
In order when petroleum pipeline leaks petroleum pipeline to be carried out drainage in the pressure release, the utility model provides a kind of pressure release drainage type sealing jig.
The purpose of this utility model is come specific implementation by the following technical programs:
Pressure release drainage type sealing jig, comprise the columniform jig body that is formed by two semicircular circular arc plate butt joints, and jig body edge fit is made as flanging, be respectively equipped with the injecting glue groove of annular in the inboard, two ends of jig body, be provided with metal o-ring one in the inboard of each injecting glue groove, jig body in the middle of the described metal o-ring of twice has draining hole, and described draining hole is communicated with drainage tube.
Offer several gum-injecting ports at described injecting glue groove, each described gum-injecting port is connected with a rubber injecting valve.
Described gum-injecting port is evenly distributed on the circumference of described injecting glue groove.
Be provided with otic placode in jig body, and have bolt hole at otic placode, connect by clamping bolt.
Pressure release drainage type sealing jig described in the utility model seals by the pipeline to leak, and the gel of the metal o-ring at two ends and injecting glue groove inside can encapsulate leak, and carries out drainage by draining hole, alleviates internal pipe pressure.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing of the quick repairing device of the described elbow of the utility model embodiment.
Fig. 2 is the sectional structure chart of the quick repairing device of the described elbow of the utility model embodiment.
Fig. 3 is the structural drawing of rubber injecting valve.
Embodiment
As Figure 1-3, the described pressure release drainage type sealing of the utility model embodiment jig, comprise the columniform jig body 1 that is formed by two semicircular circular arc plate butt joints, and jig body 1 edge fit is made as flanging 11, be respectively equipped with the injecting glue groove 12 of annular in the inboard, two ends of jig body 1, be provided with one metal o-ring 13 in the inboard of each injecting glue groove 12, the jig body in the middle of the described metal o-ring 13 of twice has draining hole 14, and described draining hole 14 is communicated with drainage tube.
Offer several gum-injecting ports 15 at described injecting glue groove 12, each described gum-injecting port 15 is connected with a rubber injecting valve.
Described gum-injecting port 15 is evenly distributed on the circumference of described injecting glue groove 12.
Be provided with otic placode 16 in jig body, and have bolt hole at otic placode 16, connect by clamping bolt.
Pressure release drainage type sealing jig described in the utility model seals by the pipeline to leak, and the gel of the metal o-ring at two ends and injecting glue groove inside can encapsulate leak, and carries out drainage by draining hole, alleviates internal pipe pressure.
