The hydrophobic segment includes: a water collecting pipe, a pipe cap and a tee joint; the outer steel pipe of protecting includes: the outer protective steel pipe of the working pipe and the outer protective steel pipe of the drainage joint are both additionally provided with radial lengthened plates; the sliding heat insulation pipe bracket comprises: the heat insulation tile, the pipe clamp, the base and the support bottom plate; the heat insulating material comprises: one or more of heat-insulating materials such as high-temperature glass wool, aluminum silicate needled blanket, rock wool, nano-pore aerogel, calcium silicate tile and the like.
The drain pipe is arranged on the side surfaces of the working steel pipe and the working elbow and is positioned in the outer steel pipe protecting pipe of the working pipe; one end of the drain pipe is connected with the drain joint, and the other end of the drain pipe and the working elbow are led out of the outer protective steel pipe of the working pipe.
The working pipe outer protection steel pipe is L-shaped, wherein the upright section of the L-shaped working pipe outer protection steel pipe is sleeved on the upright section of the working elbow, and the upright section of the L-shaped working pipe outer protection steel pipe is a long circular pipe. The long circular pipe is a long circle with a cross section, and the long circle is formed by connecting and enclosing two semicircles through two parallel lines; the length of the two parallel lines is determined according to the thermal displacement.
The outer protecting steel pipe of the hydrophobic joint is a long round pipe.
The working steel pipe and the drainage joint are pre-biased in respective long round pipes.
The working steel pipe, the working elbow, the drain pipe and the drain joint are supported by the sliding heat insulation pipe bracket.
The heat conduction between the working pipe, the pipe bracket and the outer protective steel pipe is isolated through the heat insulation tile blocks by the sliding heat insulation pipe bracket, the base and the bracket bottom plate are not welded, and the sliding heat insulation pipe bracket can slide when the working pipe is heated and expanded.
The utility model has the advantages that: the drain pipe is arranged on the side surface of the working steel pipe, the outer protection steel pipe is led out together with the working steel pipe in the outer protection steel pipe, the drain pipe is omitted, the outer protection steel pipe and a heat insulation material are additionally arranged, the moving space of the working steel pipe is not influenced, and meanwhile, the working steel pipe, the drain joint and the heat insulation material are effectively protected; by additionally arranging the radial lengthened plate (namely, adopting the long round pipe) on the outer protection steel pipe and pre-partially installing the working steel pipe and the hydrophobic joint, the problem that the heat-insulating layer and the hydrophobic joint are prevented from being extruded after the pipeline is heated and expanded is better solved by utilizing the smaller outer protection steel pipe. The utility model has the advantages of convenient site construction, safety, reliability and strong applicability.
