Abstract

The utility model discloses a leakage protector for the arc drainage soldering of a pipeline, which can be applied to fast soldering constructions in emergency constructions, such as the perforation leakage and the theft leakage of pipelines with various calibers for crude oil supply, water supply, heat supply and the like. The leakage protector disclosed by the utility model comprises an arc column body, a drainage short joint and a multi-purpose connecting pipe, wherein the drainage short joint is sequentially in threaded connection with the multi-purpose connecting pipe and the arc column body, and the arc column body is provided with an arc bottom face. The leakage protector disclosed by the utility model is reasonable in structure, convenient and fast in threaded connection, and flexible in application and operation, and can play double roles in sealing and relieving pressure for the pipelines. By adopting the leakage protector disclosed by the utility model, the difficulties such as incomplete pressure relief and great loss caused by liquid leakage in common liquid emergency leakage protection constructions of various pipelines are solved; simultaneously the construction efficiency is improved, and safe production is ensured; and if the liquid in the pipeline is an oil product, the oil product drained from the leakage protector can be collected in a storage container for recycling, and therefore, the leakage protector facilitates energy conservation and environment protection.

Description

Pipeline arc drainage welding leak-proof device
Technical field
The utility model belongs to pipeline rapid welding leak repairing tool, particularly leak-proof device is welded in the drainage of pipeline arc, can be applicable to the pipeline of various bores, such as the rapid welding construction of the emergent constructions such as the perforation leakage of various crude oil, water supply, hot duct, free call on sb. else's expense through illegal means leakage.It is larger to be particularly useful for the interior liquid pressure release overbottom pressure of pipeline, and welding is used in the longer situation of pressure release time, in conjunction with the online welding technique of pipeline, realizes mending-leakage leak-stopping operation safely and fast.
Background technique
At present, in the perforation of carrying out various pipes, the operation of free call on sb. else's expense through illegal means leak stopping leak-stopping, often experience is larger because of liquid pressure release overbottom pressure in the pipeline, the pressure release time is longer, that have even situation that can't pressure release brings difficulty and challenge for the construction of mending-leakage leak-stopping, brings hidden danger to safety in production simultaneously, cause liquid to leak in a large number, economic loss is serious.Traditional leak stopping leak-stopping method is to squeeze in the Leak hole with " wood chip " or " round steel ", thereby reduce or the interior leaked liquid of prevention pipeline, and then add tubing and carry out weld job, the shortcoming of this method is that wood chip or the round steel squeezed into are poorly sealed, ageing inaccurate, the situation of leak stopping failure often appears changing because of pipeline liquid pressure, its main cause: the one, traditional leak stopping mode does not provide pipeline liquid pressure release channel, do not have the drainage channel build-up of pressure to assemble, thereby cause mending-leakage to construct unsuccessfully.The 2nd, do not take seal approach, cause the part to gush and leak or seepage.
Summary of the invention
The purpose of this utility model is the defective for prior art, and pipeline arc drainage welding leak-proof device is provided, the instantaneous leaking-stopping welding that makes it be applicable to various bore pipelines, various common liquid pipelines.When overbottom pressure is larger in pipe, can the liquid drain in it out, guarantee the success rate of welding procedure.
The utility model is achieved in that pipeline arc drainage welding leak-proof device comprises curved circular cylinder, drainage pipe nipple and multiplex connecting tube, and the drainage pipe nipple is threaded successively with multiplex connecting tube and curved circular cylinder, and the curved circular cylinder is provided with lower arcuate surface.
Multiplex connecting tube is provided with and connects internal thread and be connected outside thread, and its body top is provided with spanner side, can be connected with drainage pipe nipple or plug.In the welding by the drainage pipe nipple to liquid drain in the pipeline, use the multiplex connecting tube of plug shutoff after the welding.
Compared with prior art the utlity model has following useful effect: the utility model is rational in infrastructure, and it is convenient and swift to be threaded, and uses flexible operation, pipeline is had sealing and pressure release dual functions.The difficult problems such as pressure release is clean in the emergency leakage blocking construction of various pipes common liquid, the leaked liquid loss is large have been solved.Simultaneously, has good using effect in raising efficiency of construction, safety in production.If ducted liquid is oil product, drainage oil product out can focus on the reservoir vessel in it, still can processing and utilization, be conducive to energy saving, protection of the environment.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: pipeline arc drainage welding leak-proof device comprises curved circular cylinder 3, drainage pipe nipple 1 and multiplex connecting tube 2, drainage pipe nipple 1 is threaded successively with multiplex connecting tube 2 and curved circular cylinder 3, and curved circular cylinder 3 is provided with lower arcuate surface 9.Multiplex connecting tube 2 is provided with and connects internal thread 5 and be connected outside thread 6, and its body top is provided with spanner side 8, can be connected with drainage pipe nipple 1 or plug, realizes drainage and sealing function.The inner circle of curved circular cylinder 3 is provided with internal thread and connects with the outside thread 6 that is connected of multiplex connecting tube 2, and the radian of its lower arcuate surface 9 and the external diameter of soldered pipeline match.Drainage pipe nipple 1 two ends body is equipped with outside thread, and body lower end outside thread connects with the internal thread 5 that is connected of multiplex connecting tube 2.
During use, the arc sealing effect of curved circular cylinder 3 dependence lower arcuate surface 9, cover is attached on the pipe leakage hole that needs welding, and the utility model is welded on the pipeline.If need drainage, on drainage pipe nipple 1, connect again other pipeline or other flexible pipe of bondage.
The design of the radian of lower arcuate surface 9 is according to the corresponding processing of external diameter radian size of common various pipes, can be according to the outer diameter tube size of reality, the model of processing can be respectively: 2 inch, 3 inch, 4 inch, 6 inch, 8 inch, 10 inch, 12 inch, 16 inch, in view of the of the present utility model lower arcuate surface 9 of the outer diameter tube more than 16 inch surface radian in using than reality relatively level and smooth, so design no longer separately.Drainage short circuit 1 is one section two nipple joint, adopts the common standard screw thread, is convenient to connect and uses.
