Description
Technical field
The present invention relates to a kind of making and use method of blowing pipeline device, particularly a kind of blowing pipeline quick-replaceable
Blasting piece device and method.
Background technology
In order to ensure pipeline cleaning inside, it is to avoid the debris such as dust, iron rust, welding slag inside pipeline are blocked up in the process of running
Plug pipeline, stuck valve even damage equipment, before pipeline construction completes to put into production, are required to carry out pipe-line purging or blow
Sweep operation.
Pipeline for nominal diameter more than or equal to DN600, general use is manually entered inside pipeline and is cleaned；It is right
It is general that pipeline is introduced compressed air into using shutoff valve behind the door in pipeline of the nominal diameter less than or equal to DN100, then open valve
Door release pressure carries out air purging；For nominal diameter in the pipeline of DN150 to DN550, typically use and add rupture disk
Method carries out airblasting purging.
Airblasting purging generally adjusts blowing pipeline flow first, is then installed on by the end flange of purging pipeline
Companion flange, adds asbestos board as rupture disk between two pieces of flanges, will form confined space by purging pipeline；On pipeline
Temperature or the appropriate interface such as manometer be continually fed into compressed air, when pipeline closed space inner air pressure gradually rise to
During the limiting pressure that can bear more than rupture disk, rupture disk will rupture suddenly, and the compressed air in pipeline instantaneously expands rapidly
And sprayed at a high speed from explosion mouthful；Simultaneously the debris such as dust, iron rust, welding slag in pipeline under the purging of high velocity air from explosion mouthful
Discharge.It is repeated several times blow off, you can reach the requirement of pipeline cleaning inside standard.
Above by the method that companion flange adds rupture disk is installed, blow off finishes and is required for removing all each time
Flange fastening bolt, after replacing rupture disk, then installs companion flange and fastens whole connecting bolts, it is necessary to the common work of many people
Make, and because every pipeline needs repeatedly purging to can be only achieved cleanliness standard, change rupture disk need to remove bolt with
The workload of fastening bolt is very big, and accumulating time is very long, and blow off efficiency is very low.
