Description
Technical field
The utility model relates to a kind of thermal insulation apparatus, particularly a kind of detachable heat-insulation device of the insulation of the Subzero valve for fluid storage and course of conveying.
Background technique
In the production process of the industries such as oil-gas mining, petroleum processing, chemical industry, pharmacy, power plant, fluid storage and course of conveying are mostly with the loss of heat and cold, and the insulation of pipeline, valve, flange, heat exchanger and other special-shaped equipment just becomes energy-saving and cost-reducing key point.Traditional heat preserving method is to adopt inside to swathe heat preserving and insulating material, and appearance swathes the glass cloth method of swabbing again, this method outward appearance ugliness, and glass cloth is short working life, need to often change.Some unit starts shell to make into the metal materials such as galvanized iron sheet or thin aluminum sheet in recent years, extended working life, increased insulation aesthetic appearance, but still deposit some problems, as heat insulating work must on-the-spotly be processed, course of working complicated and time consumption, product casing intensity is low, run into and trample easy distortion etc., especially valve, flange etc. often need the position of maintenance, maintenance or replacing, can not restore, again processing and fabricating as long as just open, not only cause waste, and affect the normal production run of device.
CN200910024563.3 discloses a kind of incubation chamber of high temperature resistant soft outsourcing material, although solved fast assembling-disassembling problem, product appearance is too fat to move, and aesthetic property is poor, can not bear external force, and interface connects employing nylon buckles, connects complexity, and intensity is low.CN201110061206.1 discloses the valve insulating sleeve that a kind of central body is rigidity coating, guaranteed combining closely between thermal insulating soft layer and valve in chamber, but valve insulating sleeve and handwheel position, top are still soft structure, although there has been the zipper structure at two ends and top to guarantee to open soon performance, but incubation chamber entirety can not pressure-bearing, zipper seal easily damages, and working life is short.CN200620027399 provides a kind of upper and lower asymmetric incubation chamber, though have wire gaze between thermal insulation layer and protective coating, wire gaze, outside thermal insulation layer, can not combine closely by protective coating thermal insulation layer.CN200920099616 and CN201220140361 provide a kind of upper and lower asymmetric glass steel material incubation chamber shell mechanism, its course of working complexity, two screws described in its technological scheme are not enough to support the tension force that the incubation chamber after installing need to be born, especially large size valve incubation chamber often needs tens screws, dismounting is very complicated, wastes time and energy; Meanwhile, what in technological scheme, use is that glass fibre reinforced plastic material flame retardant property is lower, at petrochemical industry, uses and is subject to certain restrictions.
In prior art, common deficiency is to be: external protection is not integral rigidity structure, bears external force poor performance, at pressurized or trample be easily cause cracking or distortion; Thermal insulation layer and protective layer are not combined closely, and during dismounting, easily come off; Thermal insulation layer or directly contact valve or contact with valve with glass fibre cloth parcel again, causes occurring heat conduction, reduction effect of heat insulation; Thermal insulation layer adopt be all the soft thermal insulating materials such as alumina silicate, Magnesiumaluminumsilicate, composition silicate, glass wool, rock wool, produce and using process in, the powder of above-mentioned material easily waft to it or suction lung in, operator are caused and are had a strong impact on.
In addition, after the valve installation thermal insulation apparatus of cryogenic freezing medium, in thermal insulation apparatus, have the condensed water that steam condensation becomes, especially in long-term use in summer, can make to accumulate in thermal insulation apparatus large quantity of moisture, not only because thermal-protective coating makes moist and affects effect of heat insulation, also can corrode valve, this just needs to discharge in time the ponding forming.
