Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to a prefabricated elbow of a thermal insulation pipe. Background Art

[0002] Prefabricated direct buried insulated elbow is a kind of insulated pipe fittings. The insulation elbow is composed of a high-density polyethylene outer sleeve, a polyurethane foam insulation layer and an inner working steel pipe tightly combined. The insulation elbow is mainly used for the turning of insulated straight pipes.

[0003] However, in the process of using the existing elbow, since the elbow has a large weight like the insulation pipe, it is often necessary to use lifting equipment to lift it during installation. Since the insulation pipe is mostly a straight pipe, there is no need to pay too much attention to the angle during installation. However, when installing the elbow, both ends of the elbow need to be connected to the insulation pipe, and the two ends of the elbow are not in the same straight line. Therefore, when assembling the elbow, the angle of the elbow needs to be adjusted back and forth to avoid deviation in the installation position of the other insulation pipe, resulting in the existing bracket or groove and the insulation pipe cannot be used in conjunction with each other. At present, when installing the elbow, the elbow is usually lifted by a lifting equipment, and then the work is Personnel adjust the angle of the elbow back and forth, and then align and connect it with another insulated pipe. However, during the implementation of the method, after the elbow pipe fitting is connected to another insulated pipe, the angle of the elbow cannot be adjusted again. As a result, once the installation angle of the elbow deviates, the elbow often needs to be removed or the bracket, groove, etc. need to be adjusted again, resulting in unnecessary waste, increasing the cost of installing the insulated pipe, and extending the construction period of the insulated pipe installation, which is not conducive to the burial of the insulated pipe. Therefore, a prefabricated elbow is proposed, in which the angle of the elbow can be adjusted after one end of the elbow is installed, so as to solve the problem that the angle of the elbow fitting is inconvenient to adjust during installation, thereby increasing the cost and period of installing the insulated pipe.
