Abstract
The utility model discloses a bellow expansion joint with a spiral flow guide inner sleeve. The bellow expansion joint comprises two welding sleeves (1), a corrugated pipe (2) and a flow guide pipe (3). The corrugated pipe (2) is connected between the two welding sleeves (1), the flow guide pipe (3) is arranged in an integral pipeline formed by the corrugated pipe (2) and the welding sleeves (1) and connected with the ends of the welding sleeves (1), and a spiral flow guide piece (4) is arranged in the flow guide pipe (3). By adopting the inner sleeve structure of integrating the corrugated pipe with the flow guide pipe, the flow guide pipe is internally provided with the spiral flow guide pipe and connected to a drying pipeline, hot air flow can sufficiently stay when passing through the bellow expansion joint, functions of damping and noise reduction are further achieved, perturbance of the hot air flow is enhanced to realize complete heat transmission, the corrugated pipe can give full play to expansive action, and accordingly stress concentration after the pipeline is heated can be offset.
Description
technical field
The utility model industrially drying technical field, specifically a kind of corrugated expansion joint with spiral flow deflector water conservancy diversion inner sleeve.
Background technique
In industrially drying process, some drying apparatus, as the air channels such as petrochemical industry, electric power, heat supply, boiler smoke duct, Ferrous Metallurgy, cement, boats and ships, machinery, pipeline etc., because the inside and outside temperature temperature difference is large, cause localized stress inhomogeneous, produce distortion, the equipment that affects when serious is used function.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of corrugated expansion joint with spiral flow deflector water conservancy diversion inner sleeve, adopts the mode of pipeline inner sleeve, realizes and subdues temperature difference stress, thereby temperature deformation is controlled to key position.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of corrugated expansion joint with spiral stream guidance inner sleeve, comprise two sections of soldering sleeves, bellows and honeycomb ducts, described bellows is connected between two sections of soldering sleeves, it is inner and be connected with the end of two sections of soldering sleeves 1 that described honeycomb duct is built in integrated piping that described bellows and soldering sleeve form, and described honeycomb duct inside arranges spiral flow deflector.
The ripple number of described bellows is 5-10.
Described bellows adopts stainless steel to make.
The helix angle angle 15-35 ° of described spiral flow deflector, pitch 30-50mm.
The utility model adopts bellows in conjunction with the inner sleeve structure of honeycomb duct, and in honeycomb duct inside, spiral flow deflector is set, be connected to drying duct, hot air flow, through out-of-date, realized hot air flow is fully stayed, and have shock-absorbing denoising function, hot air flow has strengthened flow perturbation at this, fully conduct heat, bellows is given full play to expansion, thereby offset the stress causing after pipeline is heated, concentrates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, this spiral stream guidance inner sleeve corrugated expansion joint, comprise two sections of soldering sleeves 1, bellows 2 and honeycomb duct 3, described bellows 2 is connected between two sections of soldering sleeves 1, it is inner and be connected with the end of two sections of soldering sleeves 1 that described honeycomb duct 3 is built in integrated piping that described bellows 2 and soldering sleeve 1 form, and described honeycomb duct 3 inside arrange spiral flow deflector 4.
As preferred mode, the ripple number of described bellows 2 is 5-10.
As preferred mode, described bellows 2 adopts stainless steel to make.
As preferred mode, the helix angle angle 15-35 ° of described spiral flow deflector 4, pitch 30-50mm.
The utility model in use, first bellows 2 and two sections of soldering sleeves 1 are connected to form to integral sleeve pipe, honeycomb duct 3 is built in this integral sleeve pipe and is connected with outer sleeve two ends, honeycomb duct 3 inside arrange spiral flow deflector 4, this device is connected between Two stage dryer pipeline, hot air flow is through out-of-date abundant formation flow-disturbing, and has shock-absorbing denoising function.Outside weldings sleeve pipe 1 is welded to connect with bellows 2, stabilized structure.Different from gas flow temperature in pipe according to drying pipeline diameter, different dimension compensation amounts is set, design is applicable to the bellows 2 of size.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
