Abstract
The utility model discloses an adjustable through-wall sealing sleeve for prefabricated directly-buried heat-preserving pipes, comprising a steel main body, a sealing rubber ring, a movable check ring and a bolt barge piece, wherein the steel main body comprises a center steel pipe and two steel rings; the two steel rings are respectively fixed at two ends of the steel pipe; a plurality of pin holes are arranged on one steel ring; the sealing rubber ring is arranged in the steel main body; the movable check ring is sleeved on a heat-preserving pipe and arranged in the steel main body; a screw hole is arranged on the bolt lapel piece; the bolt lapel piece is inserted in the pin hole; and a bolt is in bolt connection in the screw hole. The adjustable through-wall sealing sleeve for the prefabricated directly-buried heat-preserving pipes has the advantages that the situation that water seeps from the pipeline to a small chamber no longer happens in the small chamber after the adjustable through-wall sleeve is used; the phenomenon of gas rising is reduced at the utmost; and equipment, valves and the like in the small chamber are effectively protected.
Description
Technical field
The utility model relates to a kind of sealing oversleeve, especially, relates to a kind of prefabricated direct-buried thermal insulation pipe with adjustable sealing to through the wall oversleeve.
Background technique
Central heat supply is the public utilities that public character is very strong, and winter heating is the basal needs of the northern area of China people's lives.In the winter of severe cold, see sometimes to occur " steaming " phenomenon on the road.After particularly entering freeze-up, underground water can penetrate into the phenomenon that the cell of some poor sealing occurs by service pipe, and this is because cold water runs into equipment, the pipeline of little Indoor Thermal becomes due to the steam.This situation to the walking of citizen, vehicle in the urban district, travel and bring very large inconvenience, and very easily cause the generation of traffic accident because affecting sight line.
The model utility content
The utility model overcomes the defective of prior art, a kind of prefabricated direct-buried thermal insulation pipe is disclosed with adjustable sealing to through the wall oversleeve, comprise: the steel part main body, it comprises a center steel pipe and two steel loops, described two steel loops are separately fixed at the two ends of described steel pipe, and are provided with several pin-and-holes on one of them steel loop; O-ring seal, it is arranged on described steel part body interior; Movable back-up ring, it is nested with on described thermal insulation pipe and is arranged on described steel part body interior; Bolt is refuted sheet, has screw on it, and described bolt is refuted sheet and is inserted into described pin-and-hole inside, is bolted with bolt in the described screw.
Preferably, a kind of prefabricated direct-buried thermal insulation pipe of the present utility model can be changed after the long-time use of described O-ring seal is aging with adjustable sealing to through the wall oversleeve, has prolonged the working life of oversleeve through walls.
Preferably, a kind of prefabricated direct-buried thermal insulation pipe of the present utility model uses the bolton bolt to refute sheet and plays fastening effect with adjustable sealing to through the wall oversleeve, described steel part main body, has realized the adjustability function.
Prefabricated direct-buried thermal insulation pipe of the present utility model is with adjustable sealing to through the wall oversleeve; used behind the adjustable oversleeve through walls and no longer occured to seep water to cell from pipeline in the cell; maximum possible reduces " steaming " phenomenon, and the equipment in the cell, valve etc. have been played effective protection.
Description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION schematic representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As depicted in figs. 1 and 2, steel part main body 1 is placed on the pipeline, push in the steel part main body 1 after the O-ring seal 2 internal surface coating lubricating oil, steel part main body 1 should be filled up overwood chock (uniform) with pipeline enclosure, make and keep between the two with one heart, offset is controlled in the 2mm, notes: the construction bolt of steel part main body 1 is refuted the one side of sheet 4 and bolt 5 should be towards the body of wall inwall; Movable back-up ring 3 is placed on the pipeline.
With the welding of the reinforcing bar in steel part main body 1 and the body of wall, then carry out cement casting, must guarantee that cement and steel part main body 1 are in conjunction with closely, to reach good water tightness.Cement contact conduit enclosure is avoided in the measure that should properly protect, and prevents that the cement after pipeline is cured when operation from scratching.
Compress in movable back-up ring 3 pushed in the steel part main body 1, bolt is refuted in the pin-and-hole that sheet 4 inserts on the steel part main bodys 1, and be screwed into bolt 5, tight a bolt gradually 5 until bolt is refuted sheet 4 just is fixed in the pin-and-hole.Evenly tighten all bolts 5, it is partially sealed not tight to prevent that the degree of tightness inequality from causing.
Annual heat supply need check and tight a bolt 5 once when beginning and finishing after the operation, the discovery seepage enhanced leaktightness that tights a bolt at any time.O-ring seal 2 can recharge replacing in case lose efficacy.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
