In above-mentioned technical proposal; aerogel layer is set to by the internal layer of insulation cover, aeroge has the good characteristics such as heat-insulated, high temperature resistant, light weight so that better heat preservation; investing the fluorubber outside aeroge can play protection aeroge, the effect to aeroge integral reinforcing.
Further, the heat-insulation layer outside valve body and valve rod frame includes solid heat-insulation layer and gas heat insulating layer, and the heat-insulation layer is divided into heat-insulation layer and lower heat-insulation layer, and the upper heat-insulation layer passes through screw or bolt connection with lower heat-insulation layer.
In above-mentioned technical proposal, it is divided into solid with gas heat insulating layer by by heat-insulation layer so that better heat preservation, heat-insulation layer is divided into upper heat-insulation layer causes convenient installation with lower heat-insulation layer.
Further, the solid heat-insulation layer material of the heat-insulation layer is set to carbon aerogels, and the solid heat-insulation layer is set to the internal layer of heat-insulation layer, the solid heat-insulation layer directly with the wall contacts of ball valve.
In above-mentioned technical proposal, carbon aerogels are conductive, can eliminate the electrostatic of valve.
Further, located at the outside of solid heat-insulation layer, the gas heat insulating layer is inflated airbag to the gas heat insulating layer of the heat-insulation layer, and the air bag is close to the outer wall of solid heat-insulation layer.
Further, the material of the air bag is fluorubber, and the thickness of air is 3~10mm in the air bag so that the whole volume of valve is not too large.
The beneficial effects of the invention are as follows:
1st, heat-insulation layer is provided with by the outside of valve body and valve rod frame, and insulation cover is provided with valve rod and valve rod frame so that comprehensive insulation is carried out to ball valve so that insulation construction is tight, heat insulation effect is improved；Heat-insulation layer is tightly invested on valve outer wall by frictional force so that heat-insulation layer is brought into close contact with valve body so that heat insulation effect is greatly improved；
2nd, carbon aerogels are set to by by the inner layer material of heat-insulation layer, with this material, enable to the insulating power of valve to greatly improve, the weight of valve will not be increased substantially, the electrostatic on valve can also be eliminated；Insulating gasbag is provided with by the outside in heat-insulation layer so that the effect of insulation can be significantly improved.
