Description
Technical field
This utility model relates to a kind of hanger device, particularly to a kind of hanger device for corrosive pipeline detection.
Background technology
In gas exploitation course, owing to natural gas containing corrosive gas, liquid, can corrode and adopt defeated pipeline, it is understood that to corrosive pipeline degree, need that the lacing film identical with pipe material is installed in different pipe sections and detect corrosive pipeline characteristic.
Corrosion coupon is sent out and is also weight loss method, weight loss method is the method for the detection corrosion rate of a kind of classics, this method is that the metal testing plate of known weight and size rule is put in detected etching system, take out after the period of exposure of certain time, weigh after carefully cleaning and processing, calculate average corrosion rate according to the relation of test piece mass change and exposure time.Obtained by weight loss method is the average corrosion rate in a period of time, it can be observed that the surface corrosion pattern of test piece, thus the extent of corrosion of the corrosive goods confrontation pipeline obtained in gas exploitation course in natural gas.
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 owing to manifold pressure is bigger, during this lacing film corrosion testing device works, film hangers is very likely followed pressure medium and is swung, if the time cycle is longer, it is easy to the installation position of lacing film corrosion testing device with pipeline is caused damage, thus affects the carrying out of Corrosion monitoring test.
Utility model content
The purpose of this utility model is to provide a kind of hanger device for corrosive pipeline detection, thus ensures that the film hangers in the hanger device of this kind of corrosive pipeline detection can reliably fixing with inner-walls of duct be connected.
In order to solve the problems referred to above, this utility model a kind of for corrosive pipeline detection 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, it is characterized in that: film hangers end connects flexible support member, 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 a kind of 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 film hangers end connects elastic supporting member for supporting optical member, when hanger device is complete with Pipe installing, at pipe radius in the radial direction, film hangers produces interference and deformation with pipeline, thus ensures that hanger device is during carrying out Corrosion monitoring, can not move with pressure medium, effectively stablize film hangers.
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 a kind of hanger device embodiment 1 for corrosive pipeline detection in this utility model.
Detailed description of the invention
The embodiment 1 of a kind of hanger device for corrosive pipeline detection in this utility model, 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.
Film hangers 3 also includes wing nut 32.The top of stainless steel tube 34 has screw thread, stainless steel tube 34 surrounding to have hole, the position in hole in front and back with left and right cross arrangement, and front and back with left and right perforate not on a plane, stagger up and down.The peg 31 corrosion-resistant polytetrafluoroethylmaterial material that insulate is made.Stainless steel tube center has flow-guiding channel.Lacing film bar 31 is made up of insulation resistant material, and two ends have screw thread, lacing film bar 31 to be connected by the screw thread pair at two ends with wing nut 32.
Plug 2 is made up of steel, top is hexagon 21, lower periphery is screw thread 23, plug 2 has pressure release through hole, pressure release through hole preferred center hole 22 simultaneously, and centre bore 22 upper end is provided with female thread, in order to connect relief valve 1, centre bore 22 lower end is provided with female thread, and in order to the stainless steel tube 34 of connection suspension horse 3, the internal diameter diameter of centre bore 22 is adaptive with the flow-guiding channel internal diameter of stainless steel tube.
Steel loop 4 is circular, has elasticity, and steel loop 4 welds with stainless steel tube 34 bottom outlet 33.When this kind of corrosion coupon device uses, steel loop 4 external diameter coincide with internal diameter of the pipeline, produces micro-strain.
When this kind of corrosion coupon device uses, lacing film is hung on lacing film bar 31, wing nut 32 is selected into lacing film bar 31 and fixes lacing film, with spanner, plug is screwed on test valve in steel loop 4 is lowered into christmas tree, can test.Open relief valve 1 pressure release during taking-up, with spanner plug 2 pulled down and take out film hangers 3.
It addition, other embodiments in this utility model, other kinds of valve, such as electromagnetic valve, switch valve can be selected.Wing nut 32 can carry out equivalent with the nut of phase same-action and substitute, such as hex-head nut.Elastic supporting member for supporting optical member can select other parts waiting same-action having, such as spring, ball, pad.
It addition, other embodiments in this utility model, when support body is entity, it is such as lamellar or strip, when i.e. there is no flow-guiding channel, plug can be offered pressure release through hole as the medium inlet in pipeline during pressure release.
It addition, other embodiments in this utility model, when installing hole is blind hole, lacing film bar one end is provided with the screw thread of fixing lacing film.
