Abstract
The utility model belongs to the technical field of ventilation tubes, in particular to a ventilation flexible tube. The ventilation flexible tube comprises flanges which are arranged at the two endsof the flexible tube, an expansion flexible tube is arranged between the flanges at the two ends, and the expansion flexible tube is deformed so as to adapt to the position variation between the flanges. According to the technical scheme, the expansion flexible tube is arranged between the flanges at the two ends of the flexible tube, as the expansion flexible tube has elasticity, when the ventilation flexible tube is installed, the self deformation of the ventilation flexible tube can lead the butt joint between the hole sites of the ventilation tube to be more easier, thus reducing the construction difficulty greatly and increasing the installing speed; and as the expansion flexible tube is flexible connection, the use of the expansion flexible tube reduces the transmission of vibrationand noise greatly, thus stabilizing the running state of the whole pipeline and prolonging the service life of the ventilation tube.
Description
Technical field
The utility model belongs to the ventilation duct technical field, is specifically related to a kind of vent hose.
Background technique
In the ventilation duct technical field, airduct generally is to be made by rigid material at present, and its length dimension is fixed, and can not deflect activity, make airduct consuming time longer when installing and locating, and difficulty of construction is bigger; In addition, owing to be connected to hard connection between the airduct made of rigid material, this hard connecting mode is convenient to transmit vibrations and noise, thereby influences the stable operation of whole pipeline, the working life of having reduced airduct.
Summary of the invention
The purpose of this utility model provides a kind of vent hose, and its simple structure is convenient to install, and the vibrations that produce in the time of can reducing blower fan work help the stable operation of whole pipeline.
For achieving the above object, the utility model has adopted following technological scheme: a kind of vent hose, comprise the flange that is arranged on the flexible pipe two ends, and be provided with bellows between described two end flange, bellows produces deformation to adapt to the shift in position between the flange.
As shown from the above technical solution, be provided with bellows between the flange at flexible pipe two ends in the utility model, because bellows itself has elasticity, therefore when vent hose is installed, can rely on the deformation of vent hose self and make the butt joint between the position, airduct hole become simple, thereby reduced difficulty of construction widely, improved installation rate; Because bellows itself is exactly a kind ofly to be flexible coupling, so the use of bellows significantly reduced the transmission of vibrations and noise, stablized the running state of whole pipeline, prolonged the working life of airduct.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Embodiment
As shown in Figure 1, a kind of vent hose comprises the flange 10 that is arranged on the flexible pipe two ends, is provided with bellows 20 between described two end flange 10, and bellows 20 produces deformation to adapt to the shift in position between the flange 10.
When being split type between flange 10 and the bellows 20, described bellows 20 is set in the end of coupled flange 10, and bellows 20 has clip 30 with the arranged outside of the joint of flange 10 ends, as shown in Figure 1.
Described bellows 20 has the multiple choices scheme, and such as adopting rubber hose, as preferred version of the present utility model, described bellows 20 is formed by stacking by canvas.
The tensile strength of canvas is higher, be difficult for being torn, and its stretchability is bigger, is convenient to install; The cost of canvas is lower, helps reducing engineering cost.
As the further preferred version of the utility model, described canvas is a fire-resistant tarpaulin.
The use of fire-resistant tarpaulin has improved high temperature resistant, the corrosion-resistant and flame retardant property of bellows 20 widely, thereby has guaranteed the working stability of pipe-line system, has prolonged the operating life of pipe-line system.
As the another kind of further preferred version of the utility model, the described canvas that is superimposed with each other together is at least 6 layers.
As shown in Figure 2, when adopting large fan 40 in the pipe-line system, the vibrations that caused by blower fan 40 will be comparatively obvious on the one hand, and will directly bear this vibrations as the bellows 20 of connecting pipeline, therefore bellows 20 structural strengths own be had relatively high expectations; When the wind speed of blower fan 40 was big, blast acted directly on the tube wall of bellows 20 on the other hand, and also the intensity to tube wall has proposed higher requirement.When bellows 20 is formed by stacking by canvas, and the canvas that is superimposed together is when being at least 6 layers, and bellows 20 has just had enough intensity, thereby has guaranteed the stable operation of pipeline.
During use, at first bellows 20 is set in the end of coupled flange 10, then with the external circumferential of the joint of metal crimp edge bellows 20 and flange 10 around fixing, thereby bellows 20 and flange 10 are tightened together.
Described metal flanging is any one in galvanized sheet, steel plate, aluminium sheet, aluminium alloy plate and the copper coin.
The metal flanging can be by being bolted to the end of flange 10.
