Description
Technical field
The present invention relates to mechanical engineering pipeline construction technical field, more particularly to one kind can reduce to for blowing pipeline supplemental equipment requirement method.
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 one kind can reduce to for blowing pipeline supplemental equipment requirement method.
For the problems referred to above, what the present invention was provided reduces to reaching goal of the invention for blowing pipeline supplemental equipment requirement method by following technical essential：Can reduce to for blowing pipeline supplemental equipment requirement method, including the following steps that order is carried out：
1）, be connected with compressed gas source in the arrival end of pipeline to be purged；
2）, pipeline to be purged end arrange rupture disk to seal the end of pipeline；
3）, be passed through compressed gas source in pipeline, when the internal pressure in the pipeline meets or exceeds the burst pressure of rupture disk, rupture disk ruptures, and the gas in pipeline is overflowed by the end of pipeline, completes to treat the purging of purging pipeline；And the vulnerable area of above rupture disk is located at the bottom of the seal face obtained by which.
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 is used for sealing the end of pipeline, so, during compressed gas are passed through, internal pressure in pipeline is gradually increased, when the burst pressure of rupture disk is met or exceeded, rupture disk ruptures, in pipe, gas is overflowed by breach, above procedure can cause gas in pipe 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 above flow for being passed through compressed gas 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.；Further, the vulnerable area of above rupture disk is located at by way of the bottom of its seal face for obtaining, it is heterogeneous texture i.e. using rupture disk, realized such as by thickness different or material difference, after so above rupture disk is installed on the end of pipeline, bottom of the weakest part of rupture disk just to inner bore of pipeline, when so rupture disk ruptures, breach is just right against the bottom of pipeline, this Sample Method applies to the pipeline of non-vertical state to be made, the larger impurity of density will not stop for intact rupture disk part when pipeline is gone out, would be even more beneficial to the cleaning effect to pipeline.
Further technical scheme is：
For the benefit of purging effect and convenient to carry out on long distance line when carry out subsection blowing, in step 1）Employed in the compressed gas source that arrives be portable air compressor.
For ease of anticipation rupture disk rupture time and the security improved using this method, in step 1）Or step 2）In, it is additionally included on pipeline and manometric operation is installed.
As in a kind of mechanical engineering widely used arrive can as the material of rupture disk, simultaneously facilitate burst pressure regulation and control, in step 2）The middle rupture disk that just uses is bakelized paper or the highland barley paper of individual layer multilayer.
The invention has the advantages that：
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 is used for sealing the end of pipeline, so, during compressed gas are passed through, internal pressure in pipeline is gradually increased, when the burst pressure of rupture disk is met or exceeded, rupture disk ruptures, in pipe, gas is overflowed by breach, above procedure can cause gas in pipe 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 above flow for being passed through compressed gas 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.；Further, the vulnerable area of above rupture disk is located at by way of the bottom of its seal face for obtaining, it is heterogeneous texture i.e. using rupture disk, realized such as by thickness different or material difference, after so above rupture disk is installed on the end of pipeline, bottom of the weakest part of rupture disk just to inner bore of pipeline, when so rupture disk ruptures, breach is just right against the bottom of pipeline, this Sample Method applies to the pipeline of non-vertical state to be made, the larger impurity of density will not stop for intact rupture disk part when pipeline is gone out, would be even more beneficial to the cleaning effect to pipeline.
