Description
Technical field
The present invention relates to a kind of anti-corrosion methods of buried pipeline, specifically, being a kind of bolt anti-corrosion of direct burial valve
Method.
Background technology
The form that valve well is all used when traditional buried pipeline is installed, to avoid buried pipeline valve erosion.With straight
Buried valve uses, and direct burial valve is different from conventional valves anti-corrosion, becomes valve anti-corrosion problem.It is usually required to valve in construction
Body carries out cathodic protection, and the anti-corrosion of valve body bolted on part leads to constructional difficulties, and valve body whole looping is too complicated, waste
Material, heavy workload;Without looping, easily corroded in bolted position.
Therefore the bolt anti-corrosion of known direct burial valve there are problems that it is above-mentioned various inconvenient and.
Invention content
The purpose of the present invention is to propose a kind of bolt anti-corrosion method for the direct burial valve not setting valve well.
To achieve the above object, technical solution of the invention is:
A kind of bolt anti-corrosion method of direct burial valve, it is characterised in that include the following steps:
A, with the connection bolt of the clean direct burial valve of brush cleaning;
B, package one by one is carried out to valve bolts at two ends with soft preserving and sealing clay;
C, the soft preserving and sealing clay uniformly applied is made to form the coating of a smooth-going in valve flanges bolts at two ends;
D, using anticorrosion adhesive tape elder generation winding valve both ends, then among Stagger-wrap valve, finally with anticorrosion adhesive tape by valve bolt
Wrap up it is agglomerating, directly carry out valve landfill.
The bolt anti-corrosion method of the direct burial valve of the present invention can also be further achieved by the following technical measures.
Method above-mentioned, wherein the soft preserving and sealing clay is common commercially available pipeline corrosion protection lute in.
Method above-mentioned, wherein the anticorrosion adhesive tape is common commercial polypropylene fiber anticorrosion adhesive tape or polyethylene fibre
Anticorrosion adhesive tape.
After adopting the above technical scheme, the bolt anti-corrosion method of the direct burial valve of the present invention has the following advantages:
1, anti-corrosion measure is simple and convenient to operate;
2, bolt anti-corrosion quality safety is reliable, antiseptic property is excellent;
3, antiseptic project cost is reduced.

Specific implementation mode
With reference to embodiments and its attached drawing illustrates further the present invention.
Embodiment 1
The bolt anti-corrosion method concrete operations of the direct burial valve of the present invention:
Referring now to Fig. 1, Fig. 1 is the direct burial valve scheme of installation of the embodiment of the present invention, illustrates that direct burial valve 1 installs
Cheng Hou, the direct burial valve state before carrying out anti-corrosion backfill.
Fig. 2 is the bolt connection of the direct burial valve flanges of the embodiment of the present invention.Due to direct burial valve 1 itself
Has certain Anticorrosive Character, in construction bolts anti-corrosion, only in valve flanges 2 and 5 upper flange of pipeline, 3 link position, packet
Include valve body needs corrosion-resistant to be bolted position progress anti-corrosion looping with valve deck.
Fig. 3 is the embodiment of the present invention to bolt coating antiseptic cement gum schematic diagram.It is anti-that package is carried out to connecting flange 2 and 3
When rotten, under the premise of ensuring clean, it should first pick up several soft preserving and sealing clay 6 to all connection bolts 4 with hand
Both sides progress is fully wrapped around, is then filled, is formed certain with position of the soft preserving and sealing clay 6 between bolt 4
Compared with the gradient of smooth-going.Fig. 4 is the embodiment of the present invention to bolt coating antiseptic cement gum completion schematic diagram.
Fig. 5 is the embodiment of the present invention to bolt anti-corrosion clay outer layer winding anticorrosion adhesive tape completion schematic diagram.Side by hand
Method smears flange 2 and the progress of 3 link positions of completion with special anti-corrosion sealant tape 7 to being applied by soft preserving and sealing clay 6 package
Looping first carries out looping to one side companion flange position of bolt 4, then is wrapped to the other end companion flange position of bolt 4
It twines, the marginal position that last looping flange 2 and 3 combines.During looping, it should be noted that looping of interlocking repeatedly is carried out, with true
Guarantor is fully sealed.The embodiment of the present invention is using Liaoning Shenyang aviation rubber and plastic boat star HX5839 series preserving and sealing clay.Dope
Band is common commercial polypropylene fiber anticorrosion adhesive tape.
Preservative treatment is completed with valve deck junction to 1 liang of end flanges of valve, 2 position junction and itself valve body of valve 1
Afterwards, so that it may to be filled to valve 1.
The present invention has substantive distinguishing features and significant technological progress, the bolt anti-corrosion side of direct burial valve of the invention
Method can effectively control the anti-corrosion of direct burial valve, solve the problems, such as that direct burial valve bolted on part is perishable.The present invention
Direct burial valve bolt anti-corrosion method simple practical, convenient for construction.
Above example is used for illustrative purposes only rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent
Technical solution should also belong to scope of the invention, should be limited by each claim.
