A device and method for rapidly replacing bursting discs by purging pipelines

Abstract

The invention discloses a pipe purging device capable of rapidly replacing rupture disks for purging pipelines and a method thereof. The pipe purging device comprises conical-surface flanges, pin shaft seats, pin shafts, a conical-surface clamping ring, a clamping ring connection base, a bolt, a nut, a pipe nipple and a pipe flange, wherein two conical-surface flanges are oppositely arranged on one side of the plane; the pin shaft seats are symmetrically arranged on the peripheries of outer edges of the two conical-surface flanges respectively; the conical-surface clamping ring is arranged on the peripheries of the two conical-surface flanges; one end of the pipe nipple is connected with the conical-surface flanges, and the other end of the pipe nipple is connected with the pipe flange; the other end of the pipe flange is connected with a purged pipe; the pipe flange is connected with a flange on the purged pipe through the bolt and a gasket; a rupture disk is additionally arranged between the planes of the two conical-surface flanges; through the conical-surface clamping ring, the two conical-surface flanges tightly press the rupture disk; compressed air is continuously filled into the pipe for carrying out rupture purging. The pipe purging device has the beneficial effects that the time used for replacing the rupture disks is obviously reduced, the operating efficiency is greatly improved, the device can be reused after the device is manufactured, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for making and using a pipeline purging device, in particular to a pipeline purging device and method for quickly replacing burst discs. Background technique [0002] In order to ensure the internal cleanliness of the pipeline and prevent dust, rust, welding slag and other debris inside the pipeline from clogging the pipeline, blocking the valve or even damaging the equipment during operation, it is necessary to carry out pipeline cleaning or blowing procedures before the pipeline construction is completed and put into production. . [0003] For pipelines with a nominal diameter greater than or equal to DN600, generally manually enter the interior of the pipeline for cleaning; for pipelines with a nominal diameter less than or equal to DN100, generally use compressed air to introduce into the pipeline after closing the valve, and then open the valve to release the pressure for air purge; For pipelines with nominal dia...

AI Technical Summary

Problems solved by technology

[0005] In the above method of installing a matching flange and adding a bursting disc, all the flange fastening bolts need to be removed after each blasting and purging. work, and because each pipe needs to be purged multiple times to meet the cleaning standard, the replacement of the burst disc requires a lot of work to remove the bolts and fasten the bolts, the cumulative time is very long, and the efficiency of blasting and purging is very low
