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 ", height 150-180mm, 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 straight section of 20mm and the flange of evagination 1mm;The utility model 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

Pipeline wears case flexible gland
Technical field
The utility model relates to one kind for space division industry in low-temperature fractionation (- 196 DEG C) ice chest device or natural liquid The pipeline changed in vapour pre-cooler wears case flexible gland, belongs to spatial division technology field.
Background technique
In ice chest in air separation unit, it is furnished with low temperature (- 196 DEG C) running equipment and pipeline, and by filling pearl in ice chest Light sand and positive seal nitrogen, play heat insulating function.When pipeline passes in and out ice chest through institute's aperture on ice chest panel, in pipeline and open 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, guarantee pipe There are certain displacement of the lines and angular displacement in road.
Past mostly uses " straight tube shape sealing shroud " just to can satisfy 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 various Jie of conveying Sealing between the pipeline and ice chest panel of matter disengaging ice chest also proposed increasingly higher demands, be in particular in: with The expansion of single set air separation unit production capacity, the capital equipment outer dimension for refrigeration increases with it, quantity increases therewith, causes phase The certain pipelines answered three orientation at cooling box node have biggish 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 The requirement of ice chest.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of for the close of ice chest panel Envelope, prevents the moisture in air from entering, influences the insulation effect of pearlife in ice chest, there is enough intensity, can bear larger pressure Power, the pipeline for being resistant to outdoor severe environmental conditions wear case flexible gland.
The purpose of this utility model is completed by following technical solution, and a kind of pipeline wears case flexible gland, is used It in ice chest sealing, is mounted between ice chest panel and pipeline, for the sealing shroud shaped like " imperial crown ", height 150-180mm is thick 4-6mm is spent, upper and lower ends have the straight section of 16-24mm and evagination 0.6-1.4mm to be used for the fixed flange of clip.
As preferred: the sealing shroud is made of ethylene propylene diene rubber, height 165mm, side wall with a thickness of 5mm, Upper and lower ends have the straight section of 20mm and the flange of evagination 1mm.
The utility model is used for the sealing of ice chest panel, prevents the moisture in air from entering, influences pearlife in ice chest Insulation effect has enough intensity, can bear larger pressure, is resistant to outdoor severe environmental conditions.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1, a kind of pipe described in the utility model Case flexible gland is worn in road, for ice chest sealing, is mounted between ice chest panel and pipeline, the sealing shroud is shaped like " emperor Hat ", height h=150-180mm, side wall thickness s=4-6mm, upper and lower ends have the straight section 1 and evagination 0.6- of 16-24mm 1.4mm is used for the fixed flange 2 of clip.
As preferred embodiment: the sealing shroud is made of ethylene propylene diene rubber, height h=165mm, and side wall is thick S5mm is spent, upper and lower ends have the straight section 1 of 20mm and the flange 2 of evagination 1mm.
The utility model establishes the shape and correlation ruler of " crown shape " flexible gland by research, analysis, comparison It is very little, and pass through the adjustment of caliber (d) value, the pipeline that can also meet different size uses, it is embodied in:
(a) it prevents the moisture in air from entering, influences the insulation effect of pearlife in ice chest;
(b) guarantee pipeline in the case where internal Cryo Equipment is shunk:
First is that 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 is that being avoided that when being mounted on ice chest top and forming pit and ponding because of pipeline commissioning;
(c) in the case where 2 point, not only there is enough intensity, the pressure by 1KPa can be born;It to be also resistant to reveal Its severe environmental conditions, 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, In project for 6 air separation units.
