Such as, lacing film corrosion testing device in the pipeline described in detail in the utility model patent CN202974817U description that on June 5th, 2013 authorizes.This device includes protective cap, hanger, pedestal, film hangers, hydrops cabin; hanger is fixed on above pipeline by pedestal, is cased with protective cap above hanger, is fixed with film hangers below hanger; being hung with least one set test piece on film hangers, the bottom test piece of film hangers is positioned at hydrops cabin.Although this device solves pipeline corrosion test problems, but the direction that the lacing film in this kind of lacing film corrosion testing device is arranged is the most facing one direction, and owing to being different from the pressure medium of different directions for the front scouring effect of lacing film in pipeline, after thus easily causing Corrosion monitoring, the corrosion condition of lacing film does not corresponds with practical situation, affects the accuracy of corrosivity monitor.
Utility model content
The purpose of this utility model is to provide a kind of protection against erosion hanger device, thus ensures that the lacing film in this kind of hanger device can accept in the pipeline pressure medium of different directions and wash away for the front of lacing film.
In order to solve the problems referred to above, this utility model one protection against erosion hanger device by the following technical solutions:
A kind of hanger device for corrosive pipeline detection, including plug, film hangers, film hangers includes the support body that lacing film bar and plug bottom connect, both sides and the installing hole being respectively arranged on the left side and the right side evagination before and after on support body, surrounding becomes.
As a kind of improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described installing hole is used for plug-in mounting lacing film bar.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described installing hole is through hole, and lacing film bar is respectively arranged at two ends with the screw thread for fixing lacing film.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described installing hole is blind hole, and lacing film bar one end is provided with the screw thread of fixing lacing film.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, lacing film bar the most adjacent on support body is the most in one plane.
As the another kind of improvement of a kind of hanger device for corrosive pipeline detection of this utility model, film hangers end connects flexible support member, and elastic supporting member for supporting optical member is after hanger device and Pipe installing are complete and pipe radius radial direction elastic bearing produce interference.
As another kind of further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described elastic supporting member for supporting optical member is annulus.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described support body is made up of corrosion-resistant material.
As the further improvement of a kind of hanger device for corrosive pipeline detection of this utility model, described lacing film bar is made up of insulation corrosion-resistant material.
Beneficial effect is analyzed:
In sum, a kind of hanger device for corrosive pipeline detection that this utility model provides, owing to being provided with the installing hole for fixedly mounting lacing film bar with left and right before and after surrounding becomes on support body, so that lacing film bar is after installing with film hangers, this kind lacing film in the hanger device of corrosive pipeline detection can accept in the pipeline pressure medium of different directions and wash away for the front of lacing film, so that it is guaranteed that the accuracy of corrosivity monitor.
Especially when installing hole is through hole, lacing film bar the most adjacent on support body is the most in one plane, ensure that lacing film bar does not interferes between relevant installing when, also make lacing film be fully contacted with fluid simultaneously, improve the accuracy of corrosivity monitor.
Support body is made up of corrosion-resistant material, it is to avoid lacing film falls into because support body is corroded in pipeline, extends corrosion coupon device service life.
Lacing film bar is made up of insulation corrosion-resistant material, can avoid the absorption to minute impurities during this kind of corrosion coupon device busy, avoids pipeline corrosion material also to the corrosion of the parts of other hanger devices, can improve the accuracy of corrosivity monitor simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of a kind of protection against erosion hanger device in this utility model.
Detailed description of the invention
The embodiment of protection against erosion hanger device is as it is shown in figure 1, this kind includes valve, plug, elastic supporting member for supporting optical member, film hangers for the hanger device of corrosive pipeline detection, and film hangers includes support body and lacing film bar, as shown in Figure 1.The wherein preferred relief valve of valve 1, the preferred plug of plug 2, the preferred steel loop of elastic supporting member for supporting optical member 4, the preferred stainless steel tube of support body 34, film hangers 3 includes stainless steel tube 34 and lacing film bar.Stainless steel tube 34 offers installing hole, and in the present embodiment 1, installing hole is through hole.The preferred needle-like of relief valve 1, model is DN2O-250.
