Description
Technical field
The present invention relates to a kind of rotatable corrosion coupon device, belongs to oil gas field pipeline and equipment corrosion monitoring technology neck
Domain.
Background technology
Corrosion coupon monitoring be used as corrosion monitoring system important component, with it is simple to operate, corrosion information is comprehensive, suitable
With the advantages that corrosive environment is wide, data are reliable, always by the important corrosion monitoring process as production equipment and gathering line and
Sorting basis.But many places corrosion coupon in the current defeated corrosion monitoring system of oil gas field collection occurs that come off, bend, be broken etc. and showed
As, and corrosion-monitoring data is inaccurate.
There is the reason for above-mentioned abnormal conditions in the defeated corrosion monitoring system of analytic set, mainly including it is following some：
1) stream pressure, flowed fluctuation impact cause lacing film and support frequently acutely shake cause lacing film fixing bolt loosen
And come off；
2) corrosion coupon is connected on peg, forms cantilever design, and surrender bending occurs under high velocity air impact；
3) fluctuation of stream pressure and flow produces unidirectional torsion in corrosion monitoring system causes corrosion monitoring system
Weak part (corrosion coupon) is broken；
4) deposition of elemental sulfur considerably increases the corrosion rate of lacing film so that the measurement data of corrosion coupon and actual corruption
Differed greatly between erosion data.
The phenomenon that corrosion coupon frequently comes off, corrosion monitoring is exerted a certain influence and endangered with system operation, it is main
To include the following aspects：
1) the key equipment plugging fault such as choke valve is easily caused, influences to produce；
2) corrosion-monitoring data is caused to lack, it is impossible to establish complete corrosion coupon analysis system；
3) when lacing film migrates in pipeline with air-flow, may caused by rubbing or colliding inner-walls of duct mechanical damage.
Therefore, the abnormal conditions such as occur coming off, bend, be broken for collecting corrosion coupon in defeated corrosion monitoring system, improvement
Gathering system corrosion monitor, the safe and stable operation to corrosion monitoring and system operation, improving production economy benefit has
Important meaning.

π shapes drive link 64 recovers normal condition afterwards.
In monitoring cycle, under gas shock, rotating wheel 5 rotates, and is on the one hand acted on by vortex and gravitational settling
So that the elemental sulfur in air-flow settles, on the other hand the first swingle 43 rotates under the drive of rotating wheel 5, passes through first turn
The wheel 61 and engaged transmission of the second runner 62, while the first bull stick 63, drive link 64, the second bull stick 66 are by closely interlocking drive the
Three runners 67 and the engaged transmission of the 4th runner 68, kinetic energy caused by rotating wheel 5 is passed into corrosion monitoring unit, the second swingle
44 rotate under the drive of the 4th runner 68, and corrosion coupon rotates with the second 44 bars of rotation.
Fig. 9 is the 3 dimensional drawing of π shape corrosion coupons, and Figure 10 is the three-view diagram of π shape corrosion coupons, the shape of π shapes lacing film 7
The bar shaped lacing film combined shaped of shape (length is respectively 40~80,14~28,3~7mm) identical with three sizes is identical.Such as
Fig. 9, shown in 10, in the plane of symmetry perforate of π shapes lacing film two, it is bolted and is connected π shapes lacing film 7 with the second swingle 44, make
The connection for obtaining lacing film is more firm.Secondly, π shape lacing films change the bending resistant section of conventional corrosion coupon (bar shaped lacing film), improve
Lacing film anti-bending strength.The corrosion monitor rotatably, is weakened pipeline air-flow and lacing film is rushed by π shapes lacing film
Hit, torsion effect, effectively avoid the lower corrosion coupon of gas shock effect from bending occur, be broken or the abnormal conditions such as come off.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
