Abstract
The present invention relates to a kind of nano thermal insulation cover for valve heat insulation, it is characterized in that: comprise silica gel cloth surface layer and glass fibre cloth cover, the edge of silica gel cloth surface layer and glass fibre cloth cover is interconnected, between silica gel cloth surface layer and glass fibre cloth cover, form cavity, fill nano-powder in the cavity.The thickness of described glass fiber mat surface layer is 3 ~ 5mm, and the thickness of nano-powder is 10 ~ 30mm.Nano thermal insulation for valve heat insulation cover of the present invention adopts silica gel cloth surface layer and glass fiber mat surface layer parcel nano-powder, can prevent the seepage of nano-powder, and valve surface of can fitting preferably, ensure that valve and pipeline have equal heat insulation effect; Under same insulation thickness, effect of heat insulation can improve 1/2 ~ 1/3.
Description
Technical field
The present invention relates to a kind of heat-insulating material, especially a kind of nano thermal insulation cover for valve heat insulation, belongs to heat-insulating material technical field.
Background technique
At present, the consciousness that people are energy-conservation in every production, life improves constantly, and thermal insulation coating material is widely used in various industrial pipeline, kiln, building etc.Existing conventional thermal insulating material is as asbestos, glass fiber mat, aluminium silicate wool or glass fiber cloth etc., the means increasing material thickness are mostly adopted in order to improve heat insulation effect, but because the thickness of material own increases when adopting this kind of mode, when thermal insulating material needs to be coated on pipeline, covered effect and the coated number of plies will be affected.Especially for the insulation of valve, because the structure of valve is more complicated; Existing valve heat insulation cover material generally adopts alumina silicate needle punched blanket or fibre glass chopped stand mat, the pipeline thin 1/3 ~ 1/2 that insulation thickness connects than valve two ends, and effect of heat insulation is undesirable, as increased insulation thickness, then processing difficulties, installation difficulty is high, parcel defective tightness, has also had influence on effect of heat insulation.
In prior art, nano-powder has certain application in heat-insulating heat-preserving material, as being by SiO as the eakleite of thermal insulating material
2raw material (as quartz) and CaO raw material (as lime) synthesize through water-heat transfer in autoclave.But because nano-powder exists as powder granule state, be mostly made into the heat-insulation and heat-preservation of warming plate for plane when being applied to thermal insulating material; Need the pipeline, kiln etc. (as valve) of bending winding inapplicable for some.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of nano thermal insulation cover for valve heat insulation is provided, adopt nano-powder to be incubated valve, ensure that the parcel of lagging and valve is tight, good heat-insulation effect; And prevent the leakage of nano-powder.
According to technological scheme provided by the invention, the described nano thermal insulation cover for valve heat insulation, it is characterized in that: comprise silica gel cloth surface layer and glass fibre cloth cover, the edge of silica gel cloth surface layer and glass fibre cloth cover is interconnected, between silica gel cloth surface layer and glass fibre cloth cover, form cavity, fill nano-powder in the cavity.
The thickness of described glass fiber mat surface layer is 3 ~ 5mm, and the thickness of nano-powder is 10 ~ 30mm.
Nano thermal insulation for valve heat insulation cover of the present invention adopts silica gel cloth surface layer and glass fiber mat surface layer parcel nano-powder, can prevent the seepage of nano-powder, and valve surface of can fitting preferably, ensure that valve and pipeline have equal heat insulation effect; Under same insulation thickness, effect of heat insulation can improve 1/2 ~ 1/3.
