Abstract
A kind of flange leakage protective device, comprising: the several curved panels being docked on underwater flange, the sealing ring being sleeved on pipeline, wherein be coated with fireproof seal gum at the docking of several curved panels, and dock, be equipped with washer at suit；The one side of several curved panels is Ω shape, and another side is hollow Elliptic Cylinder；And the side of hollow Elliptic Cylinder be equipped with it is several for installation bolts hole: Elliptic Cylinder at the docking of Ω shape curved panel be Ω shape corresponding with Ω shape curved panel.Gas leakage can not only be oriented export by the utility model, solve the problems, such as the accumulation of fuel gas；It can also heat radiation when enough bearing gas leakage external firing influences, play the role of firewall；Operating efficiency is substantially increased, the weight of steel structure base is reduced.
Description
Technical field
The utility model relates to protective devices more particularly to a kind of for deep water Floating Production oil storage, Unloading Device
The flange leakage protective device of portion's chunking and underwater hose junction.Belong to Offshore Engineering field.
Background technique
Currently, fire prevention thermal resistance protective layer is added on the steel structure base of marine facility, to play protection steel construction
Effect.This way is commonly referred to as the firewall of marine facility.But there is also some negative effects for this firewall, it is main
It shows as follows:
(1) since this firewall can hinder gravity-flow ventilation, it is easy to cause the tired of hydrocarbon vapours and fuel gas
Product；
(2) due to the setting of this firewall, escape route can be interfered；
(3) since this firewall can stop releasing for fire explosion energy, lead to expand explosive event flat
The coverage in platform space；
(4) due to the obstruction of this firewall, the fire-fighting ability of external fire boat is influenced whether；
(5) due to the presence of this firewall, the weight of steel structure base is increased, therefore, be easy to cause oil storage facility
Eccentric risk.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of flange leakage
Gas leakage can not only be oriented export in gases did escape by protective device, solve the tired of fuel gas
Product problem, avoids the generation because of serious consequences such as flammable gas explosion, fire, casualties, environmental pollutions；It can also
Heat radiation when enough bearing gas leakage external firing influences, and plays the role of firewall；Meanwhile structure is simple, dismounting dimension
It repairs conveniently, substantially increases operating efficiency, reduce the weight of steel structure base.
The purpose of this utility model is realized by the following technical solutions:
A kind of flange leakage protective device, it is characterised in that: include: the several curved panels being docked on underwater flange,
The sealing ring being sleeved on pipeline, wherein be coated with fireproof seal gum at the docking of several curved panels, and dock, pacify at suit
Equipped with washer；The one side of several curved panels is Ω shape, and another side is hollow Elliptic Cylinder；And hollow Elliptic Cylinder
Side is equipped with several bolts hole for installation: Elliptic Cylinder and the place of docking of Ω shape curved panel for and Ω shape curved panel phase
Corresponding Ω shape.
The material of several curved panels is phenolic resin.
The utility model has the beneficial effects that the utility model is due to the adoption of the above technical scheme, in gases did escape
When, gas leakage can not only be oriented to export, solve the problems, such as the accumulation of fuel gas, avoided because fuel gas is quick-fried
The generation of the serious consequences such as fried, fire, casualties, environmental pollution；It can also when enough bearing gas leakage external firing
Heat radiation influences, and plays the role of firewall；Meanwhile structure is simple, and dismounting is easy to maintenance, operating efficiency is substantially increased,
Reduce the weight of steel structure base.
Detailed description of the invention
Fig. 1 is the utility model structure scheme of installation.
Fig. 2 is the utility model schematic front view.
Fig. 3 be in Fig. 2 A-A to schematic cross-sectional view.
Fig. 4 is the utility model schematic top plan view.
Major Symbol illustrates in figure:
1. the first curved panel, 2. second curved panels, 3. sealing rings, 4. screws, 5. first washers, 6. first bolt spiral shells
Mother to, 7. second packing rings, 8. second bolt and nuts are to, 9. fireproof seal gums.
Specific embodiment
As shown in Figures 1 to 4, the utility model includes: to be docked at pipeline method to 6 connection types using the first bolt and nut
On orchid several curved panels (the present embodiment be two, it may be assumed that the first curved panel 1 and the second curved panel 2), using screw 4
Connection type is sleeved on the sealing ring 3 on pipeline, wherein fireproof seal gum 9, and screw are coated at the docking of several curved panels
4 and first bolt and nut to being separately installed with the first washer 5 and second packing ring 7 at 6.
The one side of above-mentioned several curved panels is Ω shape, and another side is hollow Elliptic Cylinder；And hollow Elliptic Cylinder
Side be equipped with several bolts hole, the second bolt and nut is installed to 8, second bolt and nuts in bolt hole to being equipped with the on 8
Two washers 7；Elliptic Cylinder at the docking of Ω shape curved panel be Ω shape corresponding with Ω shape curved panel.
The material of above-mentioned several curved panels is phenolic resin, has the characteristics that slim and graceful, is bolted, dismounting maintenance side
Just, setting firewall bring installation period can be greatly decreased, improve production efficiency, bring economic benefit.
In use, several curved panels of the utility model are formed a whole by the fastening of bolt washer nut.It will
After several curved panels are stitched together, by the way that bolt is passed through the bolt hole reserved on several curved panels, washer nut is used
Fastening.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
