Abstract
The utility model belongs to a sleeve heat compensator, composed of an inner sleeve, an outer sleeve provided with an injection hole and a sealing ring provided with flexible filling materials. The sleeve heat compensator is characterized in that one side of a spacer ring fixed on the inner sleeve is provided with the sealing ring, and the other side is provided with a guide ring; a connecting ring end head which is fixed on an outer cover and forms a sealing ring and the outer surface of the inner sleeve are welded by the circumferential weld. The utility model can ensure not to leak when pipe networks are pre-heated. The construction period is shortened, and the construction investment can be saved.
Description
The utility model belongs to the improvement of disposable directly buried compensation device.In recent years, in heat distribution pipe network, domesticly progressively applied disposable directly buried installation compensation device, such as Chinese patent 92216435.5.This device makes easy construction, and the green grass or young crops that has been subjected to the user narrows.But, this product structure more complicated, cost is higher, and moment of flexure is bigger during work.
The purpose of this utility model is to provide a kind of disposable directly buried installation compensator that has improved, and it is not only simple in structure, and cost is low, the intensity height, and it is more reliable to work.
The purpose of this utility model is to realize like this, promptly comprising interior cover, the overcoat that has injection orifice, the seal ring that contains stuffing box packing is in interior slip-type expansion joint, limited ring one side that puts in being fixed between interior cover and overcoat is provided with seal ring, the sealing ring is by affixed leading and ask limited ring on the coat, connecting ring and the stuffing box packing between them constitute and are positioned at termination one side of overcoat, the limited ring opposite side that puts in being fixed between interior cover and overcoat is provided with guide ring, and this guide ring is fixed on the overcoat internal surface and is arranged in cover termination one side of inserting overcoat: constitute the flexible Filler that the stuffing box packing of above-mentioned seal ring filled out by shaping filler and notes and form; Between connecting ring termination that constitutes above-mentioned seal ring and lining the outer surface of, be connected with fine and close circumferential weld.
Advantage of the present utility model is to inject flexible filler in stuffing box packing, has formed elastomeric seal ring, and the sealing when having guaranteed the displacement to axial of interior overcoat is very reliable.Annotate filler owing to can not shut down once more, thereby not leaking can guarantee the pipe network preheating time, carrying out smoothly of follow-up soldering and sealing guaranteed.In addition, the limited ring at same lining the outer surface of place between the overcoat in sealing ring and keeping at a certain distance away is arranged on, the guide ring acting in conjunction has prevented that effectively crooked the and compensator of piping erection from taking off the generation of disadvantages such as shoulder.The utility model adopts the compensating sleeve structure of injecting material filling type, the bellows structure in the substituting disposable compensator, and tube has been changed structure greatly.Dwindle the overcoat outside dimension, reduced bending moment force effectively, improved the reliability of work.When implementing this patent, only need the preheating temperature of control one-off compensator, make pipe network internal pressure stress and tensile stress all be no more than permitted value, can guarantee the safe and reliable of pipe network operation.The utility model is greatly simplified the pipe network cable laying operation, can bigger saving construction investment, shorten construction period, be particularly useful for laying of hot water, steam and chemical industry pipe network.
See the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
In the accompanying drawings, (1) is interior cover, (2) be overcoat, (3) are for being arranged on the seal ring of overcoat termination one side, (4) limited ring for putting in being welded in, (5) for being welded in the guide and limit ring on the overcoat internal surface, (6) be stuffing box packing, include the flexible filler that asbestos packing and notes are filled out, (7) are connecting ring, (8) for being welded in guide ring on the overcoat internal surface, (9) circumferential weld for connecting ring and interior cover are fixed together.In the accompanying drawings, seal ring (3) is made up of (5), (6) and (7).
