Description
Technical field
The present invention relates to steel pipe connection aperture technical field of construction with pressure, specifically a kind of pressure pipeline opening
Part flow arrangement and on-line branching method.
Background technique
City gas, water supply, heat supply or factory's chemical pipeline are frequently encountered needs on former pipeline in normal operation
The case where newly connecing branch line.And urban pipe network compares field long-distance transport pipes, complex distribution, it is on the ground to have building or public set more
It applies, work progress needs to destroy road surface more, and with stopping transportation, has some impact on to the production and living of town users；How right
Road surface or user's production and living influence in smaller situation, and the branch line connection with pressure quick to the progress of cities and towns pipeline of safety non-leakage is
Urgent problem to be solved.
At present on pipeline there are two types of outer plus branch pipe construction known technologies:
One kind is that aperture is shorted and is welded to connect with former pipeline, is shorted with permanent valve, is fixed a cutting tool entrance using tapping equipment
Pipe fitting cuts pipeline, after withdraw cutter and close valve, then valve it is suitable for reading again with newly connect branch line upper flange and couple.
Another kind is that two interfaces on pipe fitting are connect with former pipeline and new pipeline welding respectively, between tapping equipment and pipe fitting
Temporary valve is installed, cutter is withdrawn after aperture and closes valve, then another set of lower occluding device is installed again, blocking is filled in
It in pipe fitting and locks, tears equipment installation blind plate after medium is isolated from the outside open.
Above two method introduction is applied from foreign technology in the defeated petroleum of length or gas transmission line, in town gas pipe more
Using not promoted always, it has following problems to main cause in the application at present:
1) compared with the isometric defeated high pressure line of petroleum pipeline for being located at field, although the urban publics such as combustion gas, heating power and water supply are managed
Road pressure rank is low, but most positioned at down town or suburb, these regional roads prosperities, building stands in great numbers, densely populated, benefit
With above-mentioned technology, due to being mounted with valve in Tapping procedures and equipment is huge increases excavation area, and construction period is longer, sternly
Ghost image rings urban transportation and the normal life of people, and the method not had also at present solves；
2) permanent valve has leakage possible in pipeline longtime running on pipe fitting, increases conduit running risk, temporary valve
Although can dismantle after aperture, one of process of lower blocking is increased, the installation of aperture work progress is complicated for operation and makes
Forming apparatus is huge, and construction risk increases；
3) above two technology cutter is respectively positioned in tapping equipment, since its process increases with valve the height of equipment, is caused
At a distance from pipeline farther out, cutter need to move relatively long distance could cut pipeline, and cutting force input point and output to perforating cutter
Point distance is remote, and cutting is unstable, causes aperture to fail when serious.
Since there are above-mentioned drawbacks, pipeline with pressure opening technology with pressure does not adapt to the fast of current urban pipe network construction at present
Fast demand for development.
