Abstract
The utility model relates to an insulating sleeve of a dismountable manhole seal head, which consists of two fan shells. The utility model comprises a shell with flange edge and a heat preservation layer, which is characterized in that a heat preservation layer (2) is stuck on a shell (1), and the two fen shells are connected with a screw (4) through a flange edge (3) on the shell, and fixed on the manhole flange or seal head flange. The utility model has the advantages of convenient installation and dismounting, excellent heat preservation property, stability, beauty, antisepsis, rainproofness, and repeated utilization.
Description
Technical field:
The utility model relates to a kind of novel man-hole cover flange heat insulating device.
Background technique:
Traditional manhole cover flange insulation generally adopts ties up thermal insulating material earlier on the manhole cover flange, spread upon the thermal insulating material outside with clay again.This mode exists construction inconvenience, and profile is not attractive in appearance.Thermal insulating material such as can not reuse at shortcoming.Cause the big construction of waste of material to wait shortcoming slowly as maintenance.These all are the defectives of prior art.
Summary of the invention:
The purpose of this utility model provides a kind of dismountable manhole cover flange lagging.He has the dismounting easy construction, thermal insulating material and housing good integrity, and housing adopts high flame retardant glass fibre reinforced plastics or inorganic glass fiber reinforced plastic material to make, and the high beautiful shape of its intensity has reusable characteristics.
The utility model is realized by following technical characteristics: with being coated with one deck inorganic heat preservation coating in the two fan housings, will be with thermal insulating material to stick in the housing high insulating effect.Two the fan housings have can be fastening flange edge, can lagging be fastened on manhole flange or the cover flange with bolt.There is one deck elasticity pad that discharges water to prevent rainy day housing water inlet in the flange edge.
The utility model has been owing to adopted above technological scheme, only needs manhole flange lagging or cover flange lagging be fastened on the manhole cover flange get final product, so has easy construction, the characteristics of beautiful shape economical with materials.
