Description
Technical field
The present invention relates to mechanical engineering pipeline construction technical field, more particularly to a kind of pipeline configuration for facilitating implementation postwelding purging.
Background technology
After equipment or process pipe are installed, before leak test pressure testing, all pipeline should be purged, so as to the iron filings, iron rust, welding slag and other debris that are clearly retained in equipment, pipeline, in order to avoid above debris blocking pipeline, damage valve and instrument with fluid during the use of pipeline, to ensure the safe handling of the equipment such as special installation, instrument, regulating valve, pump, filter, while the also quality beneficial to product.
The means for completing the purging of pipeline in prior art are usually washing, air purging, steam blowing and the cleaning of logical ball, above method is worked well when for small-caliber pipeline, when for big-diameter pipeline,, typically up to less than completing to purge the traffic requirement of required fluid media (medium), the time required to not only extending blowing pipeline in such cases, fluid device power consumption is big purges halfway disadvantage while often also having for conventional fluid device.
Content of the invention
For above-mentioned when for big-diameter pipeline, conventional fluid device is typically up to less than completing to purge the traffic requirement of required fluid media (medium), the time required to not only extending blowing pipeline in such cases, fluid device power consumption big while often there is the problem for purging halfway disadvantage, the invention provides a kind of pipeline configuration for facilitating implementation postwelding purging.
For the problems referred to above, the pipeline configuration for facilitating implementation postwelding purging of present invention offer reaches goal of the invention by following technical essential：Facilitate implementation the pipeline configuration of postwelding purging, including pipeline and by connecting pipe compressed gas source connected with pipeline, the pipeline is in series by multistage pipeline section, and be connected by adpting flange flange between pipeline section, air inlet is provided with each pipeline section, and one end of connecting pipe is connected with the port of export of compressed gas source, and the other end connects the air inlet on any one pipeline section, and blind plate is set between the adpting flange of the pipeline section side, rupture disk is set between the adpting flange of the pipeline section opposite side.
Specifically，In this programme，The compressed gas source of setting is used for being passed through compressed gas into pipeline to be purged，The rupture disk of setting and blind plate are used for sealing each section of pipeline section respectively，So，During compressed gas are passed through the pipeline section for being sealed，Internal pressure in the pipeline section is gradually increased，When the strength degree for meeting or exceeding rupture disk，When being its burst pressure，Rupture disk ruptures，In the pipeline section, gas is accused by its side for being provided with rupture disk and is overflowed at a high speed，Above procedure can cause gas in the pipeline section to spray with high flow velocity，While when rupture disk ruptures and fluid high-speed flowing makes the attached crop that the vibrations of generation are also helped in pipe by coming off on pipeline，Can be more effectively by outside the impurity exhaust conduit in pipeline，While the flow of the above compressed gas for being passed through the pipeline section is unrestricted，Existing more compressed gas source is satisfied by the requirement of this method，As centrifugal air compressor、Piston type air compressor、Root's blower、Gas cylinder etc..Be this structure provide pipeline can in any one section of pipeline section two sections be respectively provided with blind plate and rupture disk, to realize the subsection blowing of pipeline.
Further technical scheme is：
For ease of carrying out subsection blowing to pipeline, the compressed gas source is portable air compressor.
For the benefit of the rupture time of the Stress control of this device or anticipation rupture disk, is additionally provided with pressure gauge on the connecting pipe.
As a kind of be easy to draw materials, burst pressure is easy to adjust while beneficial to the explosion sheet form for reducing purging low cost, the rupture disk is highland barley paper or the bakelized paper of single or multiple lift.
The invention has the advantages that：
This apparatus structure is simple，The compressed gas source of setting is used for being passed through compressed gas into pipeline to be purged，The rupture disk of setting and blind plate are used for sealing each section of pipeline section respectively，So，During compressed gas are passed through the pipeline section for being sealed，Internal pressure in the pipeline section is gradually increased，When the strength degree for meeting or exceeding rupture disk，When being its burst pressure，Rupture disk ruptures，In the pipeline section, gas is accused by its side for being provided with rupture disk and is overflowed at a high speed，Above procedure can cause gas in the pipeline section to spray with high flow velocity，While when rupture disk ruptures and fluid high-speed flowing makes the attached crop that the vibrations of generation are also helped in pipe by coming off on pipeline，Can be more effectively by outside the impurity exhaust conduit in pipeline，While the flow of the above compressed gas for being passed through the pipeline section is unrestricted，Existing more compressed gas source is satisfied by the requirement of this method，As centrifugal air compressor、Piston type air compressor、Root's blower、Gas cylinder etc..I.e. above structure is particularly well-suited to be relatively large in diameter the pipeline longer with pipeline.
