Abstract
The utility model discloses a non-metal wave-shaped air duct compensator, which comprises an inner sleeve pipe, one port of which is provided with a connecting flange and an outer sleeve pipe, one port of which is provided with a connecting flange, wherein the other port part of the inner sleeve pipe is sheathed with the other port part of the outer sleeve pipe; an annular groove and a sealing ring which is arranged in the annular groove are arranged on the sheathed part between the inner sleeve pipe and the outer sleeve pipe; in the inner sleeve and the outer sleeve pipe, ring plates are respectively arranged on the periphery surfaces adjacent to the connecting flanges; a corrugated pipe is sheathed between the two ring plates; space among the corrugated pipe and the periphery surfaces of the inner sleeve pipe and the outer sleeve pipe is filled with a heat-insulating layer. The utility model has the advantages that a telescopic cylinder is designed into a waviness shape; because the deformation of pipelines caused by the heat expansion and cold contraction of a ventilation system and a ventilation system can be compensated by the waviness on the telescopic cylinder, the compensation of the compensator is improved and the resistance of negative pressure of the telescopic cylinder is also improved owing to the arrangement of the waviness.
Description
Technical field
The utility model relates to a kind of pipeline compensator, just relates to a kind of nonmetal waveform air channel compensator specifically.
Background technique
In the cold and hot wind conveying and pipelines such as discharging, dust treatment of electric power, iron and steel, chemical industry, interconnecting between the import and export of all kinds of blowers, induced draught fan and the airduct, the nonmetallic air duct compensator is able to extensive use with its quality softness, characteristics corrosion-resistant, that can reduce noise and vibrations, but existing nonmetal straight plate shape air channel compensator is to determine by the straight plate extending amount on the compensator, little and the anti-negative pressure performance of compensation rate a little less than, and the also bad control of angular displacement, caused the sealability in some pipeline connection not satisfactory.
Summary of the invention
The purpose of the utility model is to provide a kind of compensation rate the big and better nonmetal waveform of sealing effect air channel compensator.
For achieving the above object, the utility model can be achieved through the following technical solutions:
Nonmetal waveform described in the utility model air channel compensator comprises that a port has the inside and outside sleeve pipe of mounting flange respectively, and the another port part of described inside and outside sleeve pipe is sleeved on together; Between the inside and outside sleeve pipe of suit part, be provided with annular groove and the seal ring that places in it; Being respectively arranged with ring flat-plate near on the inside and outside sleeve pipe outer circumferential face at mounting flange place, between two ring flat-plates, be set with bellows, the space filling between described bellows and inside and outside sleeve pipe outer circumferential face has thermal-protective coating.
Corresponding uniform being fixed with organized risers more on the mounting flange of described inside and outside sleeve pipe, and described every group of riser is connected with bearing pin by major and minor hinge plate respectively.
Advantage of the present utility model is to have adopted technique scheme, retracting cylinder is set to corrugated, because the amount of deformation that causes pipeline that expands with heat and contract with cold of exhaust and ventilation system can be compensated by the ripple on the retracting cylinder, strengthened the compensation rate of compensator, and the setting of ripple has also strengthened anti-negative pressure, the damping noise reduction function of retracting cylinder greatly, withstand voltage properties is better, helps environmental protection, make this compensator sealability especially on coal gas, power plant desulfurization pipeline effect better.And corresponding uniform being fixed with organized risers more on the mounting flange of described inside and outside sleeve pipe, and described every group of riser is connected with bearing pin by major and minor hinge plate respectively, is more convenient for realizing the compensation of nonmetal waveform air channel compensator angular displacement like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, nonmetal waveform described in the utility model air channel compensator comprises that a port has the inside and outside sleeve pipe 1,2 of mounting flange respectively, and the another port part of described inside and outside sleeve pipe 1,2 is sleeved on together; Between the inside and outside sleeve pipe 1,2 of suit part, be provided with annular groove and place seal ring 3 in it; Being respectively arranged with ring flat-plate 4 near on inside and outside sleeve pipe 1,2 outer circumferential faces at mounting flange place, between two ring flat-plates 4, be set with bellows 5, the space filling between described bellows 5 and inside and outside sleeve pipe 1,2 outer circumferential faces has thermal-protective coating 6.Corresponding uniform many group risers 7 that are fixed with on the mounting flange of inside and outside sleeve pipe 1,2, described every group of riser 7 are connected with bearing pin by major and minor hinge plate 8,9 respectively.
