Abstract
A kind of pipeline wears case flexible gland, it for ice chest sealing, is mounted between ice chest panel and pipeline, the sealing shroud is shaped like " imperial crown ", 150 180mm of height, 4-6mm of thickness, upper and lower ends have the straight section of about 16-24mm and 0.6-1.4mm of evagination to be used for the fixed flange of clip;The sealing shroud selects ethylene propylene diene monomer (EPDM) material to be made, and height 165mm, side wall thickness 5mm, upper and lower ends have the flange of the straight section and evagination 1mm of 20mm;The present invention is used for the sealing of ice chest panel, prevents the moisture in air from entering, influences the insulation effect of pearlife in ice chest, there is enough intensity, can bear larger pressure, is resistant to outdoor severe environmental conditions.
Description
Technical field
The present invention relates to one kind for space division industry in low-temperature fractionation(-196℃)Ice chest device or natural liquefied gas tank
Pipeline in pre-cooler wears case flexible gland, belongs to spatial division technology field.
Background technology
In ice chest in air separation unit, it is furnished with low temperature(-196℃)Running equipment and pipeline, and by filling pearl in ice chest
Light sand and positive seal nitrogen, play heat insulating function.When pipeline through institute's trepanning on ice chest panel into cooling box when, pipeline and opening
It needs that sealing shroud is installed between the panel in hole, is allowed to inside and outside isolation, while leaking to avoid positive nitrogen in ice chest, ensure pipe
There are certain displacement of the lines and angular displacement in road.
Past mostly uses " straight tube shape sealing shroud " and just disclosure satisfy that device since production capacity is low, equipment is small, displacement is also small
Service requirement.
But with the progress of science and technology, the increase of air separation unit equipment and the raising of production capacity are allowed to conveying various Jie
Matter also proposed increasingly higher demands into the sealing between the pipeline and ice chest panel of cooling box, be in particular in:With
The expansion of single set air separation unit production capacity, the capital equipment appearance and size for refrigeration increases therewith, quantity increases therewith, causes phase
The certain pipelines answered three orientation at cooling box node have larger displacement.
Obviously, original " straight tube shape sealing shroud " has been unable to meet our present space division manufacturing industry and large-scale natural gas liquefaction
Ice chest requires.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and a kind of sealing for ice chest panel is provided,
It prevents the moisture in air from entering, influences the insulation effect of pearlife in ice chest, there is enough intensity, larger pressure can be born,
The pipeline for being resistant to outdoor severe environmental conditions wears case flexible gland.
The purpose of the present invention is by following technical solution to complete, and a kind of pipeline wears case flexible gland, for cold
Case sealing is mounted between ice chest panel and pipeline, and the sealing shroud is shaped like " imperial crown ", height 150-180mm, thickness
4-6mm, upper and lower ends have the straight section of about 16-24mm and 0.6-1.4mm of evagination to be used for the fixed flange of clip.
As preferred:The sealing shroud selects ethylene propylene diene monomer (EPDM) material to be made, height 165mm, side wall thickness
5mm, upper and lower ends have the flange of the straight section and evagination 1mm of 20mm.
The present invention is used for the sealing of ice chest panel, prevents the moisture in air from entering, influences the thermal insulation of pearlife in ice chest
Effect has enough intensity, can bear larger pressure, is resistant to outdoor severe environmental conditions.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be described in detail:Shown in Fig. 1, it is soft that a kind of pipeline of the present invention wears case
Property sealing shroud, for ice chest sealing, be mounted between ice chest panel and pipeline, the sealing shroud is shaped like " imperial crown ", height h
=150-180mm, side wall thickness s=4-6mm, upper and lower ends have the straight section 1 of about 16-24mm and 0.6-1.4mm of evagination to be used for
The fixed flange of clip 2.
As preferred embodiment:The sealing shroud selects ethylene propylene diene monomer (EPDM) material to be made, and height h=
165mm, side wall thickness s5mm, upper and lower ends have the straight section 1 of 20mm and the flange 2 of evagination 1mm.
The present invention establishes the shape and relative dimensions of " crown shape " flexible gland by research, analysis, comparison, and
And pass through caliber(d)The adjustment of value, the pipeline that can also meet different size are used, are embodied in:
(a)It prevents the moisture in air from entering, influences the insulation effect of pearlife in ice chest;
(b)Ensure pipeline in the case where internal Cryo Equipment is shunk:
First, there is sufficiently large displacement:Axial direction ± 50mm;Radial direction ± 50mm,
Second is that there is sufficiently large angular displacement:Small end central point ± 15 °,
Third, when on ice chest top, it is avoided that and forms pit and ponding because of pipeline commissioning;
(c)In the case of the 2nd point, not only there is enough intensity, the pressure by 1KPa can be born;Also to be resistant to outdoor evil
Bad environmental condition, such as sun-resistant+80 DEG C;- 40 DEG C of low-temperature resistance;
(d)Service life reaches 10 years.
Embodiment:
According to pipe diameter, the product of five specifications such as DN80, DN200, DN400, DN600, DN900 is developed, is used for 6
In the project of a air separation unit.
Claims (2)
1. a kind of pipeline wears case flexible gland, for ice chest sealing, it is mounted between ice chest panel and pipeline, feature exists
In:The sealing shroud is shaped like " imperial crown ", height 150-180mm, 4-6mm of thickness, and upper and lower ends have that about 16-24mm's is straight
Side section and 0.6-1.4mm of evagination are used for the fixed flange of clip.
2. pipeline according to claim 1 wears case flexible gland, it is characterised in that:The sealing shroud selects ternary
EP rubbers material is made, height 165mm, side wall thickness 5mm, upper and lower ends have 20mm straight section and evagination 1mm it is convex
