Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Please refer to Fig. 1 to Fig. 5, the utility model provides a kind of air duct connecting device, can be used for the connection of engineering airduct and end especially.
This air duct connecting device comprises the vibration isolation portion 2 that two airduct connecting portions 1 and fire resistant flexible explosion-proof lamp are made, and the two ends in vibration isolation portion 2 are connected with an airduct connecting portion 1 respectively.
Preferably, fire resistant flexible explosion-proof lamp is silicotitanium cloth, certainly, also can be that other have the flexible material of explosion-proof performance.Silicotitanium cloth has excellent heat-proof aging, can be used between low temperature-70 DEG C to high temperature 300 DEG C, also there is high insulating property, its dielectric constant is 3 to 3.2, breakdown voltage 20 to 50KV/mm, and heat conductivility is excellent, also there is the performances such as resistance to ozone, oxygen, light and weathering aging, therefore, the utility model it can be used as vibration isolation connected mode in air channel for requiring high place to fire-proof and explosion-proof, to improve security performance.
Visible, adopt silicotitanium cloth can improve resistance to elevated temperatures of the present utility model, insulating properties, weather-resistant performance.Because vibration isolation portion 2 have employed fire resistant flexible explosion-proof lamp, therefore, the vibration of unit can be made not to be delivered to airduct, thus make the utility model have good anti-vibration performance.
Because the air duct connecting device in the utility model have employed the vibration isolation portion 2 that fire resistant flexible explosion-proof lamp makes, therefore, while vibration isolation, there is explosion-proof, fireproof feature, be applicable in the high environment of explosive-proof grade and use, improve safety, have the advantages that structure is simple, cost is low.
Preferably, please refer to Fig. 3 and Fig. 4, air duct connecting device also comprises press strip 3, and two ends in vibration isolation portion 2 are respectively by press strip 3 and corresponding airduct connecting portion 1.Press strip 3 is provided with multiple screw, press strip 3 can be installed on airduct connecting portion 1 by this screw.
Please refer to Fig. 2 to 4, in one embodiment, the number of press strip 3 is two, and described two press strips 3 are arranged abreast.Wherein, Fig. 3 and Fig. 4 respectively illustrates a press strip 3.Owing to being provided with two press strips 3, therefore, vibration isolation portion 2 more reliably can be fixed on airduct connecting portion 1.
In one embodiment, preferably, airduct connecting portion 1 is flange.Preferably, press strip 3 is compressed by securing member 4 and is arranged on the end face of flange.Further preferably, the end clips in vibration isolation portion 2 is held between the end face of flange and securing member 4.Like this, the edge in vibration isolation portion 2 is fixed on the end face of airduct connecting portion 1 by press strip 3 and securing member 4, improves the reliability of connection.Preferably, securing member 4 is tapping screw, can certainly be other securing members of this area routine, all belong to the protection domain of this patent.
Preferably, vibration isolation portion 2 width is the fixed edge of the outside turnover of 200mm, and side-holder for fixing is held between the end face of flange and securing member 4.Owing to have employed the fixed edge of turnover, the utility model has that compact conformation is simple, good airproof performance, easy to operate, be convenient to keep in repair and the advantage changed.
Preferably, flange has the outline of rectangle.Preferably, the length in vibration isolation portion 2 is 300mm.Certainly, also can be other length, all belong to equivalent substitute mode of the present utility model.
Below, for silicotitanium cloth, making of the present utility model and installation process are described.
First, silicotitanium cloth is cut into the shape of flange, and makes the length of silicotitanium cloth be about about 300mm; Then, by folded-out for the edge of silicotitanium cloth about 20mm to form fixed edge.Then, with press strip, the fixed edge of silicotitanium cloth is pressed on the edge of flange, then with tapping screw, press strip 3 is fixed on the edge of flange.By the way, two of silicotitanium cloth ends can be made all to be fixed on two flanges, thus the air duct connecting device in composition the utility model.During installation, an airduct connecting portion 1 is separately fixed at the air outlet of airhandling equipment, another airduct connecting portion 1 is fixed on wind passage mouth, thus airhandling equipment and air supply duct is coupled together.
