Abstract
The utility model relates to a nano insulation sleeve for valve insulation. The nano insulation sleeve for the valve insulation is characterized by comprising a silicone cloth cover layer and a glass fiber cloth cover layer; the edges of the silicone cloth cover layer and the glass fiber cloth cover layer are connected with each other; the empty chamber is formed between the silicone cloth cover layer and the glass fiber cloth cover layer and filled with nano powder; the thickness of the glass fiber mat surface layer is 3 to 5 mm; the thickness of the nano powder is 10 to 30 mm. According to the nano insulation sleeve for the valve insulation, the silicone cloth cover layer and the glass fiber mat surface layer wrap the nano powder and accordingly the leakage of the nano powder can be prevented, the nano insulation sleeve can be attached to the surface of a valve well, the same insulation effect on the valve and a pipe can be ensured, and the insulation effect can be improved by one third to one half under the same insulation thickness.
Description
Technical field
The utility model relates to a kind of heat-insulating material, and especially a kind of nano thermal insulation cover for valve heat insulation, belongs to heat-insulating material technical field.
Background technique
At present, in every production, life, the energy-conservation consciousness of people improves constantly, and thermal insulation coating material is used in various industrial pipelines, kiln, building etc. in a large number.Existing conventional thermal insulating material is as asbestos, glass fiber mat, aluminium silicate wool or glass fiber cloth etc., in order to improve heat insulation effect, mostly adopt the means that increase material thickness, but while adopting this kind of mode because the thickness of material own increases, when thermal insulating material need to be coated on pipeline, will affect covered effect and the coated number of plies.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, and pipeline that insulation thickness connects than valve two ends is thin 1/3 ~ 1/2, and effect of heat insulation is undesirable, as increase insulation thickness, 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, if the eakleite as thermal insulating material is by SiO
2raw material (as quartz) and CaO raw material (as lime) are dynamically synthetic through hydro-thermal in autoclave.But because nano-powder exists as powder granule state, when being applied to thermal insulating material, be mostly made into warming plate for the heat-insulation and heat-preservation of plane; For some, need (as valves) such as crooked pipeline of reeling, kilns inapplicable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of nano thermal insulation cover for valve heat insulation is provided, and adopts nano-powder to be incubated valve, guarantees that the parcel of lagging and valve is tight, good heat-insulation effect; And prevent the leakage of nano-powder.
The technological scheme providing according to the utility model, 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 interconnects, between silica gel cloth surface layer and glass fibre cloth cover, form cavity, in this cavity, fill nano-powder.
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 described in the utility model adopts silica gel cloth surface layer and glass fiber mat surface layer parcel nano-powder, can prevent the seepage of nano-powder, and the valve surface of can fitting preferably, guarantees that valve and pipeline have equal heat insulation effect; Under same insulation thickness, effect of heat insulation can improve 1/2 ~ 1/3.
