Description
Technical field
The present invention relates to mechanical engineering pipeline construction technical field, more particularly to a kind of pipeline configuration purging effect beneficial to postwelding.
Background technology
After equipment or process pipe install, before leak test pressure testing, all pipeline should be purged, to be clearly retained in equipment, the iron filings in pipeline, rust, welding slag and other debris, 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, also it is beneficial to the quality of product simultaneously.
The means completing the purging of pipeline in prior art are usually washing, air purging, steam blowing and the cleaning of logical ball, above method is respond well when for small-caliber pipeline, when for big-diameter pipeline, conventional fluid device typically up to less than completing to purge the traffic requirement of required fluid media (medium), not only extends blowing pipeline required time, fluid device power consumption is big, often also purge halfway disadvantage simultaneously in such cases.
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), not only extend blowing pipeline required time in such cases, fluid device power consumption is big, often also purge the problem of halfway disadvantage simultaneously, the invention provides a kind of pipeline configuration purging effect beneficial to postwelding.
For the problems referred to above, the pipeline configuration purging effect beneficial to postwelding that the present invention provides reaches goal of the invention by following technical essential：Purge the pipeline configuration of effect beneficial to postwelding, the compressed gas source with pipeline be connected including pipeline and by connecting pipe, described pipeline is in series by multistage pipeline section, and it is connected to pass through adpting flange flange between pipeline section, it is provided with air inlet on each pipeline section, one end of connecting pipe is connected with the port of export of compressed gas source, the other end connects the air inlet on any one pipeline section, and blind plate is set between the adpting flange of this pipeline section side, rupture disk is set between the adpting flange of this pipeline section opposite side, and the vulnerable area of described rupture disk is located at the bottom of the seal face obtaining by it.
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 each section of pipeline section is sealed respectively，So，During compressed gas are passed through the pipeline section being sealed，Intrinsic pressure in this pipeline section is gradually increased，When the strength degree meeting or exceeding rupture disk，When being its burst pressure，Rupture disk ruptures，In this pipeline section, gas is provided with the side of rupture disk and is accused by it and overflows at a high speed，Above procedure can be making gas in this pipeline section spray with high flow velocity，During rupture disk rupture simultaneously and fluid high-speed flowing makes the vibrations of generation also help the attached crop in pipe to be come off by pipeline，Can be more effectively by outside the impurity exhaust conduit in pipeline，The flow of the above compressed gas being passed through this pipeline section is unrestricted simultaneously，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, by way of the vulnerable area of above rupture disk is located at the bottom of seal face obtaining by it, rupture disk is adopted to be heterogeneous texture, realized such as by thickness difference or material difference, after so above rupture disk is installed on corresponding pipeline section, the bottom just to this pipeline section endoporus for the weakest part of rupture disk, when so rupture disk ruptures, breach is just right against the bottom of this pipeline section, the pipeline that this composition of sample applies to non-vertical state makes, the larger impurity of density will not stop for intact rupture disk part when going out pipeline, would be even more beneficial to the cleaning effect to pipeline.
Further technical scheme is：
For ease of pipeline is carried out with subsection blowing, described compressed gas source is portable air compressor.
The for the benefit of rupture time of the Stress control of this device or anticipation rupture disk, described connecting pipe is additionally provided with pressure gauge.
As a kind of be easy to draw materials, burst pressure is easy to adjust, is beneficial to reduce the explosion sheet form of purging low cost simultaneously, described rupture disk is Semen avenae nudae paper or the bakelized paper of single or multiple lift.
The invention has the advantages that：
1、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 each section of pipeline section is sealed respectively，So，During compressed gas are passed through the pipeline section being sealed，Intrinsic pressure in this pipeline section is gradually increased，When the strength degree meeting or exceeding rupture disk，When being its burst pressure，Rupture disk ruptures，In this pipeline section, gas is provided with the side of rupture disk and is accused by it and overflows at a high speed，Above procedure can be making gas in this pipeline section spray with high flow velocity，During rupture disk rupture simultaneously and fluid high-speed flowing makes the vibrations of generation also help the attached crop in pipe to be come off by pipeline，Can be more effectively by outside the impurity exhaust conduit in pipeline，The flow of the above compressed gas being passed through this pipeline section is unrestricted simultaneously，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.
2, by way of the vulnerable area of above rupture disk is located at the bottom of seal face obtaining by it, rupture disk is adopted to be heterogeneous texture, realized such as by thickness difference or material difference, after so above rupture disk is installed on corresponding pipeline section, the bottom just to this pipeline section endoporus for the weakest part of rupture disk, when so rupture disk ruptures, breach is just right against the bottom of this pipeline section, the pipeline that this composition of sample applies to non-vertical state makes, the larger impurity of density will not stop for intact rupture disk part when going out pipeline, would be even more beneficial to the cleaning effect to pipeline.
