Abstract
The utility model discloses a corrugation airway compensator which comprises an inner steel pipe and an outer steel pipe which are partly sheathed with each other and connecting flange disks which are respectively fixedly connected with the other port position of the inner steel pipe and the outer steel pipe, wherein the periphery faces of the inner steel pipe and the outer steel pipe are respectively fixedly connected with ring-shaped baffle plates and vertical plates at intervals in sequence from the interface position towards the direction of the flange disks on both sides. The vertical plates are distributed uniformly along the periphery faces of the inner steel pipe and the outer steel pipe; a non-metal corrugated pipe is fixedly sheathed on each of the two ring-shaped baffle plates to form a sealing ring cavity; a heat-insulating sealing layer is arranged in each of the sealing ring cavities; the vertical plates are connected with each other through a telescopic connecting rod; the heat-insulating sealing layer is sheathed in a flexible net cover; the outer ring faces of the ring-shaped baffle plates are respectively fixedly connected with a pressure ring which extends to the inner side of the sealing ring cavity. The corrugation airway compensator with the structure can ensure the compensation of the compensator, and simultaneously though the heat-insulating sealing layer is crushed, the heat-insulating sealing layer can not be absorbed into a pipeline. The service life of the corrugation airway compensator is prolonged.
Description
Technical field
The utility model relates to and is used to send, the compensator on the exhaust duct, especially relates to ripple air channel compensator.
Background technique
At electric power, iron and steel, the cold and hot wind of chemical industry is carried and discharging, in the pipelines such as dust treatment, all kinds of blowers, interconnecting between the import and export of induced draught fan and the airduct, ripple air channel compensator is with its quality softness, corrosion-resistant, the characteristics that can reduce noise and vibrations are able to extensive use, but compensator existing deficiency in existing ripple air channel mainly shows: one, the air channel compensator easily causes the sealed insulation layer that is positioned at the sealing ring cavity radially outwards to be subjected to displacement in telescopic process and is extruded to the ripple chamber of nonmetal bellows, has directly influenced the compensation rate of compensator; Its two, the air channel compensator causes the fragmentation of sealed insulation layer in easily and influences the heat-insulating and sealing effect at telescopic process, and when negative pressure occurs in the pipeline, it is interior and lose the sealing heat-blocking action that broken sealed insulation layer will be inhaled into pipeline.
The model utility content
The purpose of this utility model is to provide a kind of ripple air channel compensator at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be taked following technical proposals:
Ripple described in the utility model air channel compensator, it comprises the mounting flange that partly is sleeved on inside and outside steel pipe together and is connected in described inside and outside steel pipe other port respectively; Be fixed with ring baffle and riser at interval successively from jointing respectively to both sides flange plate direction on inside and outside steel pipe outer circumferential face, described riser is along the uniform setting of the outer circumferential face of inside and outside steel pipe; Thereby fixed cover is equipped with nonmetal bellows and forms a sealing ring cavity on described two ring baffles, is provided with sealed insulation layer in described sealing ring cavity; Described riser is connected by shrinking connecting-rod, it is characterized in that: described sealed insulation layer is sleeved in the flexible guard; Be fixed with a pressure ring that in the sealing ring cavity, extends on the outer ring surface of two ring baffles respectively.
Advantage of the present utility model is described sealed insulation layer is set in the flexible guard, and is being fixed with a pressure ring that extends in the sealing ring cavity on the outer ring surface of two ring baffles respectively.Since the existence of pressure ring, thereby just stoped sealed insulation layer to be extruded in the ripple chamber of nonmetal bellows, guaranteed the compensation rate of compensator; Simultaneously because sealed insulation layer is sleeved in the flexible guard, though sealed insulation layer broken can not be inhaled in the pipeline yet, improved the effect of sealed insulation layer, prolonged the working life of ripple air channel compensator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, ripple described in the utility model air channel compensator, it comprises the mounting flange 3,4 that partly is sleeved on inside and outside steel pipe 1,2 together and is connected in described inside and outside steel pipe 1,2 other ports respectively; Be fixed with ring baffle 5,6 and riser 7,8 at interval successively from jointing respectively to both sides flange plate 3,4 directions on inside and outside steel pipe 1,2 outer circumferential faces, described riser 7,8 is along the uniform setting of outer circumferential face of inside and outside steel pipe 1,2; Thereby fixed cover is equipped with nonmetal bellows 9 and forms a sealing ring cavity 10 on described two ring baffles 5,6, is provided with sealed insulation layer 11 in described sealing ring cavity 10; Described riser 7,8 is connected by shrinking connecting-rod 12, and described sealed insulation layer 11 is sleeved in the flexible guard 13; Be fixed with a pressure ring 14,15 that in sealing ring cavity 10, extends on the outer ring surface of two ring baffles 5,6 respectively.
