Abstract
The utility model relates to a tee bend is strideed across to polyurethane direct -burried, including trunk line and small transfer line, the trunk line includes first steel pipe and first sleeve pipe, outwards is equipped with thermoelectric net zone of heating between first steel pipe and the first sleeve pipe in proper order, the aluminium foil layer, and a rigid polyurethane foam blanket, small transfer line include second steel pipe and second sleeve pipe, are equipped with the 2nd rigid polyurethane foam blanket between second steel pipe and the second sleeve pipe. The utility model discloses an advantage embodies: can guarantee to stride across heat preservation three -way temperature through thermal electricity net zone of heating, the aluminium foil layer can be radiated the three -way temperature that keeps warm, guarantees inside temperature to low temperature anti -radiation that can be external reduces external low temperature affected, reaches nearly 70% reflection effect, has guaranteed the temperature of insulating tube.
Description
Technical field
This utility model relates to transmission pipeline field, is specifically related to a kind of direct burried polyurethane spanning tee.
Background technology
Insulating tube is a kind of heat distribution pipeline device with good thermal insulation property, is mainly used in transmission high temperature air, steam, water, heat conduction wet goods fluid media (medium). Insulating tube is widely used, and has extensive application in industries such as chemical industry, petrochemical industry, heating power, solar thermal energies, and in the such as field such as deep-sea oil, solar energy thermal-power-generating, also outstanding aobvious key, produces a very large impact the Cost And Performance of whole system.
Current spanning tee pipe heat insulation effect is bad, by having the situation of heat loss.
Utility model content
The purpose of this utility model is for deficiency of the prior art, it is provided that the direct burried polyurethane spanning tee of a kind of high insulating effect.
For achieving the above object, the utility model discloses following technical scheme:
A kind of direct burried polyurethane spanning tee, including main pipeline and branch pipe(tube), main pipeline includes the first steel pipe and first sleeve, successively to being externally provided with thermoelectricity net zone of heating between first steel pipe and first sleeve, aluminium foil layer, first hard polyurethane foams layer, branch pipe(tube) includes the second steel pipe and the second sleeve pipe, is provided with the second hard polyurethane foams layer between the second steel pipe and the second sleeve pipe.
Further, the density of described hard polyurethane foams layer is 60kg/m3-80kg/m3.
Further, described thermoelectricity net zone of heating realizes electrified regulation by the wire guide connection external power source on main pipeline tube wall.
Further, described wire guide place is provided with sealing ring.
The disclosed a kind of direct burried polyurethane spanning tee of this utility model, has the advantages that
Can ensure to cross over the temperature of insulation threeway by thermoelectricity net zone of heating; The temperature of insulation threeway can be radiated by aluminium foil layer, it is ensured that internal temperature, and low temperature antiradiation that can be extraneous, reduces extraneous low temperature effect, reaches the reflecting effect of nearly 70%, it is ensured that the temperature of insulating tube.
