Abstract
The utility model discloses a chain-type pipeline leaking stoppage fixture, which is a pipy leaking stoppage fixture capable of being sleeved with the outer side of a pipeline, a sealing piece is arranged between the pipy leaking blockage fixture and the pipeline, and the wall of the pipy leaking stoppage fixture is formed by connecting a plurality of coaxial arc-shaped linking battens through chains. The wall of the pipy leaking stoppage fixture is divided into a plurality of coaxial arc-shaped linking battens which are connected in series through chains, and the quantity of the serially connected arc-shaped linking battens can be adjusted according to the size of the external diameter of the pipeline, so that the sealing piece and the outer wall of the pipeline are always clung to each other and the leaking stoppage effect is good.
Description
Technical field
The utility model relates to a kind of pipework accessory, is specifically related to a kind of chain pipe plugging chucking tools.
Background technique
When the equipment in process units, oil pipeline and storage, often a variety of causes such as congeal because of burn into and cause pipe perforation, crackle, pipeline internal medium is leaked, untimely because of leak stopping, the thing that leaks directly jeopardizes production safety, destroys surrounding environment, causes economic loss.
For realizing the stopping transportation pressure leak stopping, Chinese invention patent CN101354104B discloses a kind of chain pipe plugging chucking tools, comprise locking chain, leak stopping sheath, sealing gasket, fastening screw, described leak stopping sheath is locked the chain constraint and is positioned on the locking chain, sealing gasket sticks on the leak stopping sheath, locking chain one end is provided with the chain hook, and the chain hook is connected by fastening screw with the locking chain, and described leak stopping sheath is provided with the seal that passes sealing gasket.The present invention so not only be fit to the less pipeline of outside dimension, also is fit to the bigger pipeline of outside dimension owing to be provided with the locking chain, also is applicable to the pipeline section that has certain taper and the leak stopping of irregular pipeline or container simultaneously; The leak stopping sheath is provided with location, seal cones, the effect that can play location, hole, fixing seal pad and assist to seal, and compared with prior art, leak stopping is convenient to operation, and plugging effect is good.But this invention needs to guarantee the locking chain and is in tensioning state constantly, so that the leak stopping sheath is pressed in sealing gasket in the outside of pipeline, this just depends on the coupling mechanism force of locking chain, operator's difference, the locking degree of locking chain also can change, occur the situation that sealing gasket and the pipeline outside is not adjacent to easily, lose the leak stopping effect.
Summary of the invention
The utility model purpose provides a kind of chain pipe plugging chucking tools, and this structure is applicable to the pipeline of various outer diameter size, and is convenient to operation, and leak stopping is quick.
For achieving the above object, the technical solution adopted in the utility model is: a kind of chain pipe plugging chucking tools, for being sheathed on the tubulose covering leaks clamping in the pipeline outside, be provided with Sealing between described tubulose covering leaks clamping and the pipeline, the tube wall of this tubulose covering leaks clamping utilizes the chain serial connection to form by the coaxial arc link lath of complex root.By said structure, can adjust the quantity of the arc link lath of serial connection, thereby make Sealing and pipeline outer wall be adjacent to constantly according to the size of outer diameter tube, plugging effect is good.
In the technique scheme, the tube wall inboard of described tubulose covering leaks clamping is provided with the injecting glue groove, and the position corresponding to described injecting glue groove at least one described link lath is provided with gum-injecting port, the sealing joint strip of described Sealing for forming in gum-injecting port injects described injecting glue groove.Wherein, the quantity of injecting glue groove can be according to the leak case increase and decrease of reality.
Further technological scheme, described link lath is provided with the positioning through hole that at least two branches occupy described injecting glue groove both sides, and described positioning through hole runs through the both sides of described link lath, is equipped with described chain in the described positioning through hole.
In the technique scheme, be provided with regulating block in the gap between the two adjacent described link laths, if can not form full circle after the complex root link lath serial connection, then the available adjustment piece is mended the gap between the two adjacent chain connecting plate bars, assists sealing, and plugging effect is good.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model is divided into the tube wall of tubulose covering leaks clamping the coaxial arc link lath of complex root and utilizes chain to be connected in series, can be according to the size of outer diameter tube, adjust the quantity of the arc link lath of serial connection, thereby make Sealing and pipeline outer wall be adjacent to constantly, plugging effect is good.
2. the utility model can link the radical of lath according to the external diameter increase and decrease arc of pipeline, is applicable to the leak stopping of the pipeline of various outer diameter.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the structural representation of chain connecting plate bar among the embodiment one;
Wherein: 11, chain; 12, injecting glue groove; 13, link lath; 14, positioning through hole; 16, gum-injecting port; 17, regulating block.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to Fig. 1, shown in Figure 2, and a kind of chain pipe plugging chucking tools, for being sheathed on the tubulose covering leaks clamping in the pipeline outside, its cross section can be annulus, also can be elliptical ring.
Be provided with Sealing between described tubulose covering leaks clamping and the pipeline, the tube wall of this tubulose covering leaks clamping utilizes chain 11 serial connections to form by the coaxial arc link lath 13 of complex root.By said structure, can adjust the quantity of the arc link lath of serial connection, thereby make Sealing and pipeline outer wall be adjacent to constantly according to the size of outer diameter tube, plugging effect is good.
In the present embodiment, the tube wall inboard of described tubulose covering leaks clamping is provided with injecting glue groove 12, position corresponding to described injecting glue groove 12 at least one described link lath 13 is provided with gum-injecting port 16, and described Sealing is for injecting the sealing joint strip that forms in the described injecting glue groove 12 from gum-injecting port 16.
Described link lath 13 is provided with the positioning through hole 14 that two branches occupy described injecting glue groove 12 both sides, and described positioning through hole 14 runs through the both sides of described link lath 13, is equipped with described chain 11 in the described positioning through hole 14.
If can not form full circle after the complex root link lath serial connection, then available adjustment piece 17 benefits are gone into the gap between the two adjacent chain connecting plate bars 13, assist sealing, and plugging effect is good.
The utility model is divided into the tube wall of tubulose covering leaks clamping the coaxial arc link lath of complex root and utilizes chain to be connected in series, can be according to the size of outer diameter tube, adjust the quantity of the arc link lath of serial connection, thereby make Sealing and pipeline outer wall be adjacent to constantly, plugging effect is good.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
