Abstract
The utility model relates to a branch-compensation lower drain nozzle seat of a prefabricated directly-buried steam heat-insulating pipe, and the branch-compensation lower drain nozzle seat comprises a working steel pipe, a rolling support, an outer protecting steel pipe and heat-insulating glass cotton, wherein a branched end of the working steel pipe is a water collection pipe, and a drain pipe is installed on the water collection pipe. The water collection pipe is connected with the outer protecting steel pipe through a corrugated compensation device. The water collection pipe on the branched end of the working steel pipe is connected with the outer protecting steel pipe through the corrugated compensation device, the corrugated compensation device can compensate 10mm both in the transverse direction and in the axial direction, so that weld seams can be protected against cracking caused by the fatigue stress, and the safe running of a directly-buried steam pipe network can be ensured. Meanwhile, the lower end of the water collection pipe is provided with a flange plate connecting port, so that if necessary, the sewage can be discharged in time and water scale in the pipeline can be cleared.
Description
Technical field:
The utility model belongs to a kind of heat-net-pipeline connected element, and the spy relates to the following drain nozzle seat of a kind of prefabricated direct-buried steam insulation pipe racks branch's compensation fully.
Background technique:
The application of prefabricated direct-buried thermal insulation pipe is a multi-disciplinary systems engineering; And its technology content of steam insulation pipe direct-burried is bigger; A node surplus direct-buried steam pipe has ten comprises heat insulation fixed bearing, compensation elbow, strengthens threeway, steam trap connection, moisture discharge device, reducer and compensator etc.Direct-buried steam pipeline belongs to pressure piping, and each node must be handled well, otherwise may cause engineering accident, and hidden danger property is very big.
Steam pipes due to load changes or because of other reasons steam parameters, steam pipes often run in a state of wet steam, steam condensate pipeline will produce more water, if not removed, water hammer occurs frequently, causing pipe vibration , resulting compensator and weaknesses duct damage, therefore, in order to ensure safe operation inside the pipe, generally at low steam pipes Dian, fixed support or at the site may have a hydrophobic condensation devices.And at present, it is that collector pipe and outer pillar are welded together that the steam trap connection of in steam line, installing adopts direct coupled structure (as shown in Figure 1), this structure, and it is very dangerous to be in operation, and the long-time running weld seam can produce fatigue damage, causes pipe leakage.In addition, ducted incrustation scale also is not easy to remove.
Summary of the invention:
The purpose of the utility model just is to overcome the deficiency that exists in the above-mentioned existing technology, and provides a kind of prefabricated direct-buried steam insulation pipe racks branch's compensation simple in structure, safe in utilization, reliable following drain nozzle seat.
As above design; The technological scheme of the utility model is: the following drain nozzle seat of a kind of prefabricated direct-buried steam insulation pipe racks branch's compensation; Comprise working steel tube, rolling support, external protective steel tube, insulation glass wool, the branch end on the working steel tube is a collector pipe, and drain pipe is housed on the collector pipe; It is characterized in that: be connected through ripple compensation apparatus between collector pipe and the external protective steel tube.
The lower end mounting flange interface of above-mentioned collector pipe.
The utility model is owing to be connected through ripple compensation apparatus between the branch end-collector pipe on the working steel tube and the external protective steel tube; This ripple compensation apparatus can be laterally and nose balance 10mm; Therefore can guarantee that weld seam can not ftracture because of fatigue stress, thereby can guarantee the safe operation of direct-burried steam pipe system.Simultaneously, owing to the mounting flange interface in the collector pipe lower end, ducted incrustation scale is removed in blowdown in time when needing.
Description of drawings:
Fig. 1 is the schematic representation of existing prefabricated direct buried steam pipeline drain nozzle seat.
Fig. 2 is the structural representation of the utility model.
Embodiment:
As shown in the figure: the compensation of a kind of prefabricated direct-buried steam insulation pipe racks branch is the drain nozzle seat down, by working steel tube 1., rolling support 2., external protective steel tube 3., 8. the insulation glass wool form.Branch end on the working steel tube be collector pipe 7., drain pipe is housed 6. on the collector pipe, 4. be connected through ripple compensation apparatus between collector pipe and the external protective steel tube.The lower end mounting flange of above-mentioned collector pipe is interface 5..
The utility model is that collector pipe is connected with FlexbleJoint with external protective steel tube, and it can be laterally and nose balance 10mm, can guarantee that like this weld seam does not ftracture because of fatigue stress.And collector pipe lower end mounting flange interface, but ducted incrustation scale is removed in blowdown when needing.The utility model structure proves through engineering practice, and is safe and reliable, easy to use, can guarantee the safe operation of direct-burried steam pipe system.
