in this step when being clamped in the pressure release secure component on pipeline, at first according to revealing the corresponding relation of mouth and seal parts on the gas pressure relief slot on the pressure release fastening block that forms the pressure release secure component and press seal groove and pipeline, successively be placed in pipeline outer wall on according to the circular arc resettlement groove on it every pressure release fastening block, and coordinate by the structure that is sealed and matched (as Stamping Steel Ribbon or sealant layer etc.) between adjacent pressure release fastening block and join, thereby make all pressure release fastening blocks along the circumferencial direction setting of pipeline, connect to form the pressure release secure component of parcel pipeline between all pressure release fastening blocks, then, utilize gripping members to step up all pressure release fastening blocks, make all pressure release fastening blocks be clamped on pipeline, make simultaneously between adjacent pressure release fastening block to be sealed and matched.
This step is just stepped up leak stopping bonding between seal parts and pipeline after firmly, the medium of so further avoiding leaking can impact the seal effect of seal glue, greatly improved the effect of seal, even the MEDIA FLOW of leaking under the impact of pressure release secure component is to the seal parts of both sides, seal is firm due to the seal parts, the medium that leaks can not impact the seal effect of seal glue, effectively improves the reliability of leak stopping, the problem of secondary leakage can not occur.
(4) after the pressure release secure component is completed clamping, close the Decompression valves on it, complete leak stopping.In this process, medium in pipeline enters in pressure-releasing chamber from revealing mouth under pressure, but can't discharge in pressure-releasing chamber, along with medium constantly enters, pressure in pressure-releasing chamber constantly increases, there are some media can enter into from the gap between pressure release secure component and pipeline in the press seal chamber of both sides in pressure-releasing chamber, due in the press seal chamber and be sealed and matched fully between the seal parts, and between seal parts and pipeline, time sealing is bonding, enters in the press seal chamber medium and can't discharge outside the pressure release secure component; With constantly entering of medium, the interior pressure of pressure and pipeline that flows into the part of medium in pressure in final pressure-releasing chamber, press seal chamber can form consistent, the medium of pipeline will no longer enter into leakage-baffling device this moment, thereby realize that the medium in pipeline transmits with initial pressure, assurance relevant device or operation are effectively carried out.
After this pipeline finishes corresponding work, can dismantle recycling to the pressure release secure component on it.During dismounting, first open Decompression valves and discharge the interior medium of leakage-baffling device, then unclamp the gripping members on the pressure release secure component, remove at last the pressure release secure component on pipeline, this can realize reusing of pressure release secure component.
