Abstract
A mechanism flange junction device of round air duct, is characterized in that two plug-in flanges are inserted into two round air ducts which need to be connected, then installs a flange connecting part on the two plug-in flanges and fastens the joint of the flange connecting part with a bolt. The level torus of the flange which is inserted with the round air duct is provided with a cycle of sealing strip or sealant thereon. The utility model has advantages of simple structure, convenient installation, good connection sealing with pipeline, firm and durable, can apply to the air duct connection of ducting system and pipeline connection of other similar system.
Description
The utility model relates to a kind of flange apparatus, especially a kind of machine-processed flange connecting apparatus that is used to connect round air duct.
At present in ventiduct system, the Placement of airduct mainly is at the connection end face of pipeline the cutting made from angle steel to be installed, the connection part of transplanting a cutting is bitten the angle sign indicating number of cooperation mutually and is stung bone and connect by making different shape, and pass through screw threads for fastening, collude sign indicating number being equipped with between two connecting tubes of cutting to install then, by the screw that colludes on the sign indicating number that the junction plane of angle steel is fastening.The connection set of existing airduct requires more accurate the cooperation, make manufacturing and installation all comparatively complicated, and the link that connects is many, easily causes leakage.
The purpose of this utility model is: a kind of machine-processed flange connecting apparatus of round air duct is provided, makes it simple in structure, and easy for installation, and make the connection good airproof performance of pipeline enclosure, sturdy and durable.
The technological scheme that realizes the utility model purpose is as follows: a kind of machine-processed flange connecting apparatus of round air duct, comprise plug-in type flange I and plug-in type flange II, these two flanges are all served as reasons and are bent into the ring joint face structure that mutually perpendicular two anchor rings are formed, two round air ducts that need to connect can be inserted in respectively vertical surface back to and on the outer surface of the horizontal loops junction surface of these two plug-in type flanges of putting; Also comprise a flange connector, this flange connector for from the centre to two limits toward the annular ring that has a down dip, the size of this flange connector should with vertical anchor ring back to and the plug-in type flange I and the plug-in type flange II that put place in it simultaneously; Being equipped with in the joint at flange connector two ends can the movable securing means of regulating, with flange connector and place the plug-in type flange I in it to be fastened on two round air ducts that need be connected with plug-in type flange II.
Because adopt technique scheme, the round air duct that the utility model will connect is plugged on respectively on two flanges, by a flange connector that these two flanges connections are also fastening again, thus the connection of realization airduct.Compared with prior art, the utility model flange arrangement does not need the connection of complicated shape to cooperate, thereby make and install all comparatively convenient, and the link that connects is few, only need the adjusting of the securing means on the flange connector and fastening can be fastenedly connected two flanges and round air duct, thereby good airproof performance, be difficult for leaking, sturdy and durable.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the three-dimensional exploded view of the machine-processed flange connecting apparatus of the utility model round air duct
Fig. 2 is the cross section unfolded drawing of the machine-processed flange connecting apparatus of the utility model round air duct
Illustrated in figures 1 and 2 is an embodiment of the machine-processed flange connecting apparatus of the utility model round air duct.This connection set has plug-in type flange I1 and plug-in type flange II2, and these two flanges are all served as reasons and are bent into the ring joint face structure that mutually perpendicular two anchor rings are formed.Two round air ducts 4 that need to connect can be inserted in respectively vertical surface back to and on the outer surface of the horizontal loops junction surface of these two plug-in type flanges of putting.In the utility model structure, also have a flange connector 3, this flange connector 3 for from the centre to two limits toward the annular ring that has a down dip, this flange connector 3 can with vertical anchor ring back to and the plug-in type flange I1 and the plug-in type flange II2 that put place in it simultaneously.In the present embodiment, the perpendicular rings on plug-in type flange I1 and the plug-in type flange II2 is faced horizontal anchor ring be directed downwards and be bent into the summit at last triangle, forming the cross section is leg-of-mutton vertical anchor ring; And horizontal loops bent towards last level, form horizontal anchor ring with flanging.Can play a supportive role so on the one hand, increase the intensity of flange junction surface, but also when round air duct was inserted, surface of contact was smooth, prevents scratch pipe face.Certainly the both sides of these two plug-in type flanges also can be bent into the cross section of other shapes respectively, also can play same effect.
Being equipped with in the joint at flange connector 3 two ends can the movable securing means of regulating, in the present embodiment, this securing means is: respectively rivet a metal circular tube along hoop at the two ends of flange connector 3, behind the overlap joint of flange connector 3 two ends, in two metal circular tubes, wear a clamping bolt 6, and by nut, packing ring with flange connector 3 and place two plug-in type flanges in it to be fastened on two round air ducts 4 that need to connect.
The machine-processed flange connecting apparatus of the utility model round air duct and the installation process of round air duct are as follows:
1, two round air ducts 4 is inserted in respectively on the outer surface of horizontal loops junction surface of plug-in type flange I1 and plug-in type flange II2;
2, carry out the contraposition calibration;
3, pass through fixing bolt 7 with plug-in type flange and round air duct stationary positioned;
4, put flange connector 3;
5, go up Stamping Steel Ribbon or be coated with sealer;
6, two round air ducts 4 and plug-in type flange thereof are healed up;
7, flange connector 3 is positioned on two plug-in type flanges, and tightens clamping bolt 6, promptly finish whole erection.
For the ease of machine shaping, the equal available iron leather of two plug-in type flanges in the utility model and flange connector becomes.
The utility model is applicable to that the airduct of ventiduct system connects, and the pipeline that also can be used for other similar system connects.
