Description
Technical field
The present invention relates to a kind of plugging pipelines devices, and in particular to a kind of plugging pipelines instrument with pressure relief.
Background technology
Needs and the construction in city that China's pipe technology is lived with people are constantly expanded and application.Almost each row is each
Industry can be applied to pipeline, such as the water supply pipe of water service system and waste water conveyance conduit, natural gas supply system
Natural gas transportation pipeline, fresh water delivery pipe, fuel supply pipe and Boiler Steam pipe on ship etc..These pipelines are using
In, it is hit by external force, the aging of pipeline itself or the corrosion of transported medium etc. influence, pipeline fracture, pipe often occurs
There is the failure of the pumped (conveying) mediums such as the water, natural gas, fuel oil that convey leakage, not only creates great peace in the situation of road breakage
Full hidden danger can also cause very big property loss.It therefore, will be disconnected generally by sprue for pipe leakage or fracture defect
Split or the pipeline that leaks be sealed leak stopping after replace broken pipe in real time.
At present, traditional leak stopping mode mainly blocks damaged nozzle using cork and broken rag, traditional leak stopping
Method is complicated for operation, blocking time is long, needs substantial amounts of manpower；In addition, conventional pipelines capping tools is when in use, can directly by
Pipeline internal medium is enclosed in pipeline, since pipeline internal medium build pressure gradually rises, when the pressure build-up in pipeline to one
It can cause the pipeline both sides force unbalance of closure when determining degree, when capping tools is washed open by the medium in pipeline, it will give
Pipeline maintenance and replacement bring very big danger, particularly when pipeline medium is flammable explosive Jie such as natural gas, oil
During matter, it will bring huge harmfulness.
For above-mentioned technical barrier, occur in the prior art it is various it is improved after plugging pipelines instrument, example
As Authorization Notice No. be 203099206U Chinese utility model patent disclose a kind of duct closing type device, include sphere with
Relief tube has relief hole in sphere, and the inner end of relief tube is fixed in relief hole, and valve is installed on relief tube.
The plugging device of this kind of structure in sphere by setting relief hole and under the cooperation of relief tube, will quickly can be situated between in pipeline
Matter emits, and can effectively improve the security of plugging pipelines.But there are still following defects：1) it is used for the sphere of blocking pipe
It can not accomplish seamless closure with inner-walls of duct, plugging effect still needs to improve；2) relief tube as pressure release effect is separated with sphere
Set, if when the interconnection of relief tube and sphere loosens, it will effect when losing closure to pipeline pressure release, pressure release it is steady
It is qualitative low；3) sphere is directly blocked in inner-walls of duct, sphere and pipeline without corresponding connection/fixing device, pipe plugging
Security has much room for improvement with stability.
