The heat insulation elbow of above-mentioned employing Flange joint, the bending degree of the body of described heat insulation elbow is 45 °-90 °.
The beneficial effects of the utility model are:
The utility model welds suction flange and outlet(discharge) flange respectively at the two ends of heat insulation elbow, suction flange, the outlet(discharge) flange at heat insulation elbow two ends are connected with entrance point flange with the outlet end flange of prefabricated direct-buried thermal insulation pipe respectively, screw bolt and nut is adopted to complete during connection, do not need welding in construction, improve installation rate.The utility model has the advantage that linkage structure is simple, easy for installation, reliability is high, to install when connecting without the need to special professional skill, effectively can solve the matching connection problem of the prefabricated direct-buried thermal insulation pipe flange that heat insulation elbow and non-rectilinear are laid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is linkage structure schematic diagram of the present utility model.
In figure, mark is as follows: heat insulation elbow 1, tube wall 2, thermal insulation layer 3, outer pillar 4, suction flange 5, outlet(discharge) flange 6, seal washer 7, bolt 8, nut 9, prefabricated direct-buried thermal insulation pipe 10.
Embodiment
Fig. 1 shows, and the body of heat insulation elbow 1 of the present utility model is the body of bending, lays thermal insulation layer 3, be set with outer pillar 4 outside thermal insulation layer 3 outside the tube wall 2 of heat insulation elbow 1.
Fig. 1 shows, and install suction flange 5 in one end of heat insulation elbow 1, the flange sleeve of suction flange 5 and the tube wall 2 of heat insulation elbow 1 are welded to connect.At the other end end installation outlet flange 6 of heat insulation elbow 1, the flange plate of outlet(discharge) flange 6 and the tube wall 2 of heat insulation elbow 1 are welded to connect, and the flange sleeve of outlet(discharge) flange 6 is positioned at the outer end of heat insulation elbow 1.
Fig. 1 shows, and the external diameter of the flange sleeve of the internal diameter of the flange sleeve of heat insulation elbow 1 suction flange 5 and the outlet end flange of prefabricated direct-buried thermal insulation pipe 10 matches, so that the suction flange 5 of heat insulation elbow 1 is connected with the outlet end flange of prefabricated direct-buried thermal insulation pipe 10.
Fig. 1 shows, and the internal diameter of the flange sleeve of the external diameter of the flange sleeve of heat insulation elbow 1 outlet(discharge) flange 6 and the entrance point flange of prefabricated direct-buried thermal insulation pipe 10 matches, so that the outlet(discharge) flange 6 of heat insulation elbow 1 is connected with the entrance point flange of prefabricated direct-buried thermal insulation pipe 10.
