Background technology
At present, due to the liquefied petroleum natural gas line under the conditions of extremely cold, to face environment temperature relatively low more, technological requirement
The problem of higher；Therefore, for the flange in this complex condition, its thermal acoustic insulation fire protection design, to liquefied petroleum
Natural gas core process module is particularly important.Because the flange thermal acoustic insulation fire prevention part under the conditions of extremely trembling with fear is not special
Device, therefore, be badly in need of a kind of flange thermal acoustic insulation firebreak device under the conditions of extremely cold.
Utility model content
Main purpose of the present utility model is to overcome disadvantages mentioned above existing for prior art, and provides a kind of extremely cold condition
Under liquefied petroleum natural gas flange thermal acoustic insulation fireproof box, it can be under the conditions of extremely cold, to liquefied petroleum natural gas line
Flange carry out thermal insulation, sound insulation, fire prevention, solve liquefied petroleum natural gas core process module to liquefied petroleum natural gas line
The problem of strict demand of technique, substantially increase the sealing of liquefied petroleum natural gas line.
The purpose of this utility model is realized by following technical scheme：
It is a kind of it is extremely cold under the conditions of liquefied petroleum natural gas flange thermal acoustic insulation fireproof box, it is characterised in that：Including：Cladding
Prevent steam from entering between several layers of foam glass in several layers of foam glass beside liquefied petroleum natural gas flange on pipeline, brushing
Vapour locking layer, wherein, in the joint of flange, use leakage observation tube to draw；The Surface coating of foam glass has rubber slab；
Flange and pipeline surface are equipped with several layers of sound insulation rock wool, and several layers of highdensity sound panel are sealed with sound insulation rock wool, then, then are made
It is fixed with stainless steel binding strap, and forms a foam glass box.
The step of equal in width is reserved between the several layers of foam glass, vapour locking layer brushing is on step end face.
The colligation spacing of the stainless steel binding strap is maximum to be no more than 225mm.
In the space of the foam glass box and flange surface, elastic cotton is inserted, prevents steam from remaining；And superscribe outer shield
Plate, to avoid fold；The fire resistant coating on outer apron outer surface sprays again.
The beneficial effects of the utility model：The utility model is because using above-mentioned technical proposal, it can be in extremely cold condition
Under, thermal insulation, sound insulation, fire prevention are carried out to the flange of liquefied petroleum natural gas line, solve liquefied petroleum natural gas core process
The problem of strict demand of the module to liquefied petroleum natural gas tube Wiring technology, substantially increase the close of liquefied petroleum natural gas line

Embodiment
As shown in figure 1, the utility model includes：It is coated on several layers of foam on pipeline beside liquefied petroleum natural gas flange
(foam glass 1 of the present embodiment is two layers to glass 1, and first layer is bonded using first bonding agents 4；The second layer is using the second bonding
Agent 5 is bonded in the outside of first layer), brush prevented between several layers of foam glass 1 steam enter Foster 90-66 type vapour locking layers
3, wherein, in the joint of flange, drawn using Teflon leakage observation tube 6, to observe whether flange and pipeline have leakage；
The Surface coating of foam glass 1 has rubber slab 7；Several layers of sound insulation rock wool 8 are equipped with flange and pipeline surface, on sound insulation rock wool 8
Use sealant sealing there are several layers of highdensity sound panel 9 (sound panel 9 of the present embodiment is two layers), then, reuse stainless
Steel binding strap 2 is fixed, and forms a foam glass box 11.
The step of equal in width is reserved between above-mentioned several layers of foam glass 1, vapour locking layer 3 is brushed on step end face.
Above-mentioned several layers of sound insulation rock wool 8 is fixed on flange and pipeline using diameter 1mm stainless steel wires.
The colligation spacing of above-mentioned stainless steel binding strap 2 is maximum to be no more than 225mm.
In use, foam glass box 11 is installed on flange, and fixed with stainless steel binding strap 2, wherein, foam glass
Box 11 is with the space of flange surface, inserting elastic cotton 10, preventing steam from remaining.Right in leakage observation tube 6 and foam glass 1
The place of connecing is sealed with sealant 12, after the adiabatic system construction of flange is completed, completes adiabatic, sound insulation flange surface, bag
The outer casing 13 of tack fiberglass is wrapped, to avoid fold；Because the outer casing 13 of tack fiberglass is ultraviolet curing
It material, should be irradiated in the position of without sunlight direct projection using ultraviolet lamp, make its solidification；After hardening, in tack glass
The outer surface of outer casing 13 of glass steel sprays fire resistant coating 14 again, and construction of the present utility model is completed after solidification.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
