Description
Technical field
The utility model relates to a kind of adpting flange, particularly the thin metallic tubd adpting flange.
Background technique
Aqueduct is a part extremely crucial in the building, very very long process has also been experienced in the development of aqueduct, enforcement along with China's policies of reform and opening to the outside world, national economy obtains to increase fast, cities and towns dwelling house, public building and tourist facilities are built in a large number, and hot water service and domestic water supply have been proposed new requirement.Quality problem is subjected to people's common concern, and requirements in water quality is also improved constantly, and under water factory's water supply quality situation up to standard, real arrival uses the water quality level of water spot very different, and its basic reason is the secondary pollution of aqueduct to transporting water.The aqueduct description of materials is numerous, so the selection problem to the aqueduct material has just become the most important thing, therefore, the superiority of Stainless Steel Tube also more and more significantly embodies, particularly wall thickness only is that the thin-wall stainless steel of 0.6～1.2mm is in the drink water system, water heating system and with safety, the water supply system that health is put in the first place, it is safe and reliable, hygienic environment-protecting, characteristics such as economic and practical are approved by increasing people, and it is best to be proved the water supply system combination property by engineering practice, novel, one of tubing of energy-conservation and environment protection type, also be the most competitive a kind of water-feeding pipes, will be to improving water quality, improve people's quality of life and bring into play unrivaled effect.Therefore, relevant expert's prophesy: building water supply tubing finally will return to the epoch of metal tube.According to external application experience, assert that in metal tube thin-wall stainless steel is one of best tubing of combination property.
At present, in industry using is clamp-press type pipe part and plug-in type pipe part comparatively widely, and thin-wall stainless steel clamp-press type pipe part, tubing must have enough thickness to come support tubes, must limit the wall thickness that can't further reduce tubing; And plug-in type, its pipe fitting complexity, cost height.And neither be applicable to the tubing of Φ more than 40.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, and a kind of thin metallic tubd adpting flange simple and reasonable for structure is provided, and it connects closely, and is easy to install.
The purpose of this utility model is achieved through the following technical solutions: the thin metallic tubd adpting flange, it comprises flange seat, seal ring, metal tube and flanged cap, termination at metal tube is provided with horn mouth, flanged cap is placed in above the horn mouth, the outer installment of flange seat has screw, the flanged cap outer installment has the flanged cap screw, attachment screw passes the flanged cap screw and cooperates with the screw of flange seat outer installment and screw, flanged cap screws with flange seat and is connected, and in the termination of flange seat seal ring is set, and the rear portion is provided with angle in the flanged cap that mates with horn mouth in the flanged cap.
The termination of flange seat is angle or straight mouth.
The angle of the termination of flange seat or straight mouth close by side compression seal buckle in the horn mouth of the termination setting of seal ring and metal tube.
Screw and flanged cap screw are not threaded mounting hole or tapped hole.
Seal ring is the seal ring of band gradient.
By top narration as can be seen, the utlity model has following advantage: rational in infrastructure, ingenious, with low cost, connect closely, be applicable to that mainly diameter connects more than or equal to the tubing of Φ more than 50, pipe fitting can be made the link of all size, shape., threeway straight-through, threeway as all size become connect, straight-through become connect, the elbow of various angles, various inside and outside tooth joints etc.
