Abstract
The utility model provides a sealing constructional appliance which can seal the pipeline section in the clogging of a pressure pipeline. The essential technical proposal is that an air inlet at one end of the bag body of the utility model is connected with a metallic core head which vulcanized with the air inlet firmly; a metallic joint is connected with the outside of the metallic core head via screw thread. The metallic joint is connected onto a gas cylinder via a rubber pipe; when the gas cylinder inflates to the utility model, the pressure of the bag body is inflated in the pipeline; the medium of the pipeline is intercepted to be sealed with a baffle plate which has bearing function, and thus the pipeline is clogged. The utility model which is suitable for an oil pipeline and the baffle plate can process the accident of the pipeline in short time.
Description
The utility model belongs to a kind of sealing capsule, and is particularly a kind of when the pressure piping shutoff, is used for tackling or the aerated capsule of isolating pipelines medium.
For oil and gas pipes, no matter be to handle pipeline accident, still carry out the pipeline technology transformation, shutoff construction equipment that must be safe and reliable.Owing to also do not have a corresponding capping tools at present, so the technological transformation of pipeline also can't carry out at present, if pipeline generation minor accident as leakage of oil or let alone trickling, or is patched up the method for not dealing with problems completely in the pipeline outside.If pipeline generation major break down then need be taked vital measure, vital measure involves wide, and the repairing expense is high.
The purpose of this utility model provides one of a kind of reliable shutoff construction equipment---the seal for pipe joints gas-filling bag.
The purpose of this utility model is achieved in that it mainly is made up of utricule, metal core print, metal joint etc., the inlet hole of utricule one end is connected with the metal core print, the two is vulcanized together securely, and the outside at the metal core print is connected with metal joint by screw thread.Metal joint is received on the gas cylinder by sebific duct, when gas cylinder when the utility model is inflated, utricule pressure inflation in pipeline, the utricule two ends are hemisphere, with the interception of the medium of pipeline, sealing, with the baffle plate that plays the pressure-bearing effect, to pipeline enforcement shutoff.
The utility model compared with prior art, it and baffle plate can be implemented shutoff to pipeline together at short notice, in time handle pipeline accident, carry out the pipeline technology transformation, reduce the loss, and reduce and pollute.
Further describe the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of the utility model when blocking pipe.
The inlet hole of utricule 1 and metal core print 2 cure together, for preventing to draw back, the joint of the two, adopt the structure of convex-concave complementation, outside at the metal core print, be connected with metal joint 4 by screw thread, between metal core print and metal joint, accompany a circle seal ring 3, metal joint is received on the gas cylinder by sebific duct 5, inflation medium in the gas cylinder is selected nitrogen for use, when gas cylinder when the utility model is inflated, utricule is inflation in pressure piping 6, the utricule two ends are hemisphere, crude oil interception with pipeline, sealing with the plate washer that plays the pressure-bearing effect, is implemented sealing to pipeline.Utricule is that multilaminar high strength power nylon cloth is a framework material, inside and outside post the oil resistant film and constitute, its thickness is no more than 5cm.
The blank pipe bursting pressure of the sealed bladder of different size pipeline is as follows:
28 " the seal for pipe joints capsule is 1.0Mpa at φ 720 pipeline borehole blasting pressure;
22 " the seal for pipe joints capsule is 1.2Mpa at φ 529 pipeline borehole blasting pressure;
16 " and 14 " seal for pipe joints capsule is 1.5Mpa at φ 426 and φ 377 pipeline borehole blasting pressure.
This shows that the utility model can guarantee quite high safety coefficient in actual use all the time, carries out with the safety of guaranteeing construction operation.
