Abstract
The invention discloses a flange leakage protection device. The flange leakage protection device is characterized by comprising a semi-circular protective cover and a square protective cover, wherein the semi-circular protective cover and the square protective cover are fixedly connected; and semi-circular holes matched with a pipeline are formed on the semi-circular protective cover and the square protective cover. The device disclosed by the invention can be mounted in a connecting part of the pipeline and the flange. A leaking medium can be guided to be discharged to a safety region such as a sea surface as soon as leakage occurs. The device has a fireproof function.
Description
Technical field
The present invention relates to a kind of protection device, particularly relate to a kind of flange leakage protection device.
Background technology
Floating Production storage is unloaded oil carrier FPSO standpipe and is positioned at profile, the flange on standpipe and the joint face of valve
Horizontal level is in outside hull, and once junction occurs leakage accident, and standpipe inner high voltage medium may be direct
Injection hull, causes damage to device on hull and ship；If have fire to occur, then high-pressure injection flame simultaneously
Will likely cut hull, cause a serious accident.
Summary of the invention
The technical problem to be solved in the present invention is: provides a kind of overall construction intensity height, good stability, resistance to let out
The flange leakage protection device that leakage has been impacted, the joint face solving the flange and valve how prevented on standpipe is sent out
Life leaks and causes the medium revealing injection to the hurtful problem of device on hull or ship.
In order to solve above-mentioned technical problem, the technical scheme is that and provide a kind of flange leakage protection dress
Put, it is characterised in that include semicircle protection cap and square protection cap, semicircle protection cap and square protection cap
Fixing connection, semicircle protection cap is equipped with, in square protection cap, the semicircle orifice matched with pipeline.
Preferably, described semicircle protection cap is respectively coated with fire resistant coating with the outside of square protection cap.
Preferably, described semicircle protection cap and the inside of square protection cap are all welded with arc reinforcing plate.
Preferably, strip reinforcing plate is all welded in described semicircle protection cap and the outside of square protection cap.
Preferably, the internal welding of described semicircle protection cap is connected to lock rotary apparatus.
The present invention can be arranged on pipe flange connecting portion, once leaks, and bootable leaking medium discharges
To safety zones such as seas, it has fire-proof function.
It also have the advantage that
1) protection cap uses Welding Structure, and overall construction intensity is high, good stability, and resistant to leakage is impacted, can
Bear the impact that the high pressure gas leakage of intrinsic pressure 550 kilograms of pipeline produces；
2) fire resistant coating keeps its overall construction intensity and function not to be affected by neighbouring fire and high temperature, protects simultaneously
Defending the doctrine blue attachment security, fire-protection rating is up to H60～H120 grade；
3) use arc structure bottom protection cap, can effectively guide leakage medium to flow along circular arc direction, simultaneously
Bottom reinforcement structure has the space of deformation, it is allowed to jet load causes protection cap to deform, and can effectively alleviate injection punching
Hit the impact that load causes, ensure protection cap Stability Analysis of Structures to greatest extent, continue safety and guide leakage injection direction；
4) crevice corrosion that can prevent sea water infiltration from causing is sealed；
5) locking rotary apparatus can keep the opening direction of protection cap, prevents from rotating and losing efficacy；
6) protection device is divided into 2 parts, convenient narrow regions aboard ship to install.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of flange leakage protection device；
Fig. 2 is the use schematic diagram that a kind of flange leakage protection device is arranged on pipeline.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is a kind of flange leakage protection device, as it is shown in figure 1, it include one piece of semicircle protection cap 3,
One piece of square protection cap 1, two parts protection cap is respectively Welding Structure；Semicircle protection cap 3 and square protection
The outside of lid 1 is respectively coated with fire resistant coating, and semicircle protection cap 3 is equipped with and pipeline in square protection cap 1
The semicircle orifice matched, after i.e. semicircle protection cap 3 links together with square protection cap 1, two thereon
The circular hole that semicircle orifice is formed matches with pipeline.The internal welding of semicircle protection cap 3 is connected to lock rotary apparatus 2,
The inside of semicircle protection cap 3 and square protection cap 1 is all welded with arc reinforcing plate, semicircle protection cap 3 He
Strip reinforcing plate is all welded in the outside of square protection cap 1, and the internal welding of semicircle protection cap 3 is connected to locking and rotates
Device 2, for fixed-piping flange 4.
As in figure 2 it is shown, by semicircle protection cap 3 and square protection cap 1 Matching installation on pipe flange 4,
After locking rotary apparatus 2 is enclosed within the clamp nut of pipe flange 4, with bolt, two block protection cover lockings are fixed,
And the gap of coating protection cap and pipeline enclosure is filled up with fluid sealant.
