A kind of fast quick-detach leggy Corrosion monitoring piece suspension device
Technical field
The utility model relates to petroleum gas engineering fields, specifically design a kind of fast quick-detach leggy Corrosion monitoring extension
Piece device.
Background technique
Currently used piece suspension device uses vertical hanging, and there are following two big technological difficulties:
(1) in air water two-phase pipeline, the corrosion rate of pipeline different direction is different, and conventional vertical lacing film cannot be accurate
Reflect the corrosion rate of upper top (gas phase) in pipeline, bottom (air water two-phase);
(2) conventional lacing film can only at most hang 2 lacing films in same orientation, it is impossible to be used in different time, unlike material
Comparison between corrosion.
Application number CN201320672786.2 nominates " a kind of cleaning type corrosion monitoring piece suspension device " it is characterized by: cylinder
Together with flanged joint, flange is connected by isometric studs with gasket with blind flange;There are three lacing films on blind flange
Column, three lacing film columns are uniformly distributed on a concentric circles of blind flange, and there is hole in lacing film column front end, is connected by screw to lacing film;
The upper and lower part of cylinder respectively with discharge port, feed inlet connection;Cylinder lower part is connect with end socket, end socket and drain connection, then with
Bottom blow valve is connected;It is connected with main valve on main pipeline, inlet valve is sequentially connected with Flow of Goods and Materials direction on bypass duct, is hung
Piece device, outlet valve, jet chimney is connected on the pipeline between outlet valve and discharge port, and jet chimney is equipped with steam valve.It should
Utility model is connected with jet chimney on bypass duct, can carry out steam blowing to piece suspension device, make the object inside piece suspension device
All discharge piece suspension device, piece suspension device become more to clean material, and easy disassembly saves disassembly and assembly time.
The purpose of above-mentioned patent is to clean piece suspension device, easy disassembly using jet chimney.Its major defect is as follows:
(1) three pieces lacing film can only be hung, suspension quantity is few;
(2) lacing film column is connect with lacing film and blind flange, and potential difference easy to form influences monitoring accuracy.
Utility model content
It can the technical problem to be solved by the utility model is to provide one kind in view of the deficiency of the prior art
Realize the fast quick-detach leggy Corrosion monitoring piece suspension device of multi-faceted monitoring corrosion rate.
The technology employed by the present utility model is a kind of fast quick-detach leggy Corrosion monitoring piece suspension device, feature
It is: is detachable connection between the inner cylinder and outer cylinder including outer cylinder and inner cylinder, edge is axially arranged with multilayer extension on the inner cylinder
Section, every layer of section of jurisdiction area include horizontal tube section and vertical scraping section, and the horizontal lacing film area includes multiple water being circumferentially arranged
Flat lacing film hole, the vertical scraping section include the vertical lacing film hole being installed in above or below horizontal lacing film hole.
According to the above technical scheme, the horizontal lacing film area includes four horizontal lacing film holes being circumferentially evenly arranged.
According to the above technical scheme, wiper block is respectively equipped in the upper and lower side of inner cylinder.
According to the above technical scheme, it is equipped with L-type slot in one end of inner cylinder, be used for and outer cylinder detachable connection.
According to the above technical scheme, the inner cylinder is made of isolation material.
According to the above technical scheme, the outer cylinder is connected by mounting flange with main pipeline.
According to the above technical scheme, position of suspension being hung on inner cylinder and being provided with macropore, lacing film upper and lower surface can be made to connect with medium
Touching.
Have the beneficial effect that the utility model more can be accurate compared with other corrosion coupon devices acquired by the utility model
The corrosion rate situation for reflecting different direction in pipeline, is able to achieve corrosion rate of the unlike material under the same orientation of same environment
Comparison is chosen convenient for material.Piece suspension device length can be adjusted according to design simultaneously, and lacing film size can change according to demand, flexibly more
Become.Piece suspension device installation uses flanged joint, is mounted on pipeline or bypass pipe can be in outer cylinder according to pipeline emptying process demand
Upper installation blow valve, oil recovery outer cylinder and inner cylinder separate design, disassembly, replacement lacing film are easy to operate.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the A-A direction view in Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, 2, a kind of fast quick-detach leggy Corrosion monitoring piece suspension device, including outer cylinder 2 are present embodiments provided
With inner cylinder 4, the inner cylinder 4 is made of isolation material, is equipped with L-type slot 7 in one end of inner cylinder 4, inner cylinder can be prevented mobile and
Rotation, is respectively equipped with wiper block in the upper and lower side of inner cylinder 2, it is ensured that inner cylinder is with small vibration.The outer cylinder 2 passes through welded flange piece 1
It is connected with main pipeline.
Along multilayer lacing film area is axially arranged on inner cylinder 4, every layer of section of jurisdiction area includes horizontal tube section and vertical scraping section, institute
Stating horizontal lacing film area includes multiple horizontal lacing film holes 5 being circumferentially arranged, and the vertical scraping section includes being installed in horizontal lacing film hole
Above or below vertical lacing film hole 6.In the present embodiment, the horizontal lacing film area includes four levels being circumferentially evenly arranged
Lacing film hole 5.
Position of suspension is hung in the present embodiment, on inner cylinder and is provided with macropore 8, can make lacing film upper and lower surface and media contact.
4 inner wall of the utility model inner cylinder can hang lacing film up and down, can more accurate reacting pipe inside different parts
Corrosion rate, while can vertical lacing film, the corrosion rate of contrast level lacing film and vertical lacing film;Simultaneously as needed, interior
4 length of cylinder are adjustable, settable multilayer, in the mountable unlike material lacing film in same orientation, realize pair in the same orientation of unlike material
Than property test;There are various sizes of mounting holes for same position, can hang various sizes of lacing film, and can be freely combined flexibly
