Abstract
The utility model relates to a flange self-aligning type tube connecting structure, which consists of two tubes and two flange sleeves, wherein sleeve tubes of the flange sleeves are provided with limiting tables which are sleeved into to-be-connected ends of the tubes and sealed by elastic seal rings; and ring flanges of the flange sleeves are sealed by gaskets and locked by bolts. By using the elasticity and the hydraulic self-locking principle of the seal ring and the sealing lock of the two ring flanges, the tubes can be sealed and stably connected together; and meanwhile, since each seal ring has one side free when being sleeved on the sleeve tube, the seal ring can deform along with the shift of the two connecting tubes when certain flexibility generates to adapt to the allowance change for keeping the sealing performance for connection. Therefore, the tube connecting structure not only can adapt to the connection of the tubes with to-be-connected ends having different space sizes, but also can keep the sealing performance of the tubes when a certain allowance changes during the connection of the tubes, has the advantages of simple structure, sample and rapid assembly and disassembly, high pressure resistance and long service life, and is suitable for the connection of various tubes, in particular to the connection of metal-plastic composite compound tubes.
Description
Technical field: the utility model relates to a kind of pipe connecting structure, and particularly a kind of flange that utilizes carries out the firm pipe connecting structure that connects of self-locking.
Background technique: in daily life or the production process, the tubing of usefulness such as water delivery, oil transportation all needs certain connected element that they are interconnected to seal, at present tubing such as plastic cement, metal, aluminium-plastic composite pipe or steel-plastic composite pipe there is various linkage structure, wherein, the disclosed ZL200720150267.4 patent of Patent Office of the People's Republic of China provides a kind of flange type pipeline connector structure, has solved the connectivity problem of tubing such as steel-plastic composite pipe preferably.Its seal ring but still has certain deficiency: owing to need position by default screens, connect tubing and in use have certain when scratching displacement when two, to cause the seal ring can not random deformation and influence its sealing, and can not adapt to when certain surplus change is arranged when tubing connects and use.
Summary of the invention: the purpose of this utility model is to provide a kind of hydraulic pressure that can utilize to carry out the self-regualting type sealing for overcoming above-mentioned shortcoming, and can satisfying again has a surplus when tubing connects also keeps the pipe connecting structure of sealing when quantitative change is moved.
The purpose of this utility model can be achieved as follows: this flange self-regulation type pipe connecting structure mainly is made up of two tubing and connecting sleeve, described connecting sleeve is two flange covers, one end of flange cover is a flange plate and the other end is a sleeve pipe, and what sleeve pipe was with respectively that at least 1 seal ring places described two tubing respectively waits to connect in the end; Described seal ring has elasticity, lays respectively at two tubing and waits to connect between the outer surface of the internal surface of end and sleeve pipe, and wherein the external diameter of seal ring and tubing are waited to connect between the internal diameter of end and is interference fit, and the internal diameter of seal ring and the external diameter of sleeve pipe also are interference fit simultaneously; Between seal ring and flange plate, also be provided with on the described sleeve pipe and can guarantee that seal ring is positioned at the limit dais of waiting to connect end of two tubing; Seal and use locked with bolts through sealing gasket between described two flange plate.
As further improvement of the utility model: the sleeve pipe of this flange self-regulation type pipe connecting structure is provided with in 1 circle scrobicular ring or outer bulge loop at least between flange plate and limit dais.
The utility model cooperates with tubing by sleeve pipe, elastic seal ring, seal ring positions by limit dais, utilizing seal ring to have elasticity and hydraulic pressure self-lock mechanism has realized being connected sealing between the sleeve pipe of tubing and flange cover, simultaneously by between two flange plate with the sealing gasket sealing and with locked with bolts realize between the flange cover sealing with firmly be connected, can seal, firmly link together thereby make between the tubing.Meanwhile, opposite side is freely because seal ring is enclosed within on the siphunculus that the one side leans against on the limit dais, connects tubing and has when necessarily scratching displacement when two, and seal ring can be followed distortion at random, keeps the sealing that connects to adapt to all the other quantitative changeizations.Therefore, the utility model linkage structure both can adapt to wait to connect to connect between the tubing of holding spacing to vary in size maybe need refute the connection that connects when angle occurring between three-way pipe connection and tubing, can adapt to the sealing that still keeps when having certain surplus to change when tubing connects between tubing again, can tolerate any high pressure, long service life, be not subjected to the restriction of installation environment, be suitable for using in the various tubing connections, use during particularly the composite metal-plastic pipe material connects.
Description of drawings:
Fig. 1 is the schematic representation of the utility model flange self-regulation type pipe connecting structure;
Fig. 2 is another schematic representation of flange self-regulation type pipe connecting structure of the present invention.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1 and Fig. 2, show flange self-regulation type pipe connecting structure, the waiting to connect of two tubing 11,12 is inserted in two flanges covers 31,32 respectively in the end a end is a sleeve pipe 51,52, the waiting to connect of two sleeve pipes 51,52 and two tubing 11,12 respectively has 1 elastic seal ring 6 between the end, seal ring 6 is enclosed within on sleeve pipe 51,52 outer surfaces, and seal ring 6 also can be established 2,3 even more a plurality of to increase sealing.The other end of two flange covers 31,32 is promptly fastening with bolt 9 lockings between two flange plate 41,42, also has a sealing gasket 8 to seal between two flange plate 41,42.On two sleeve pipes 51,52, be provided with limit dais 2 between two flange plate 41,42 and the seal ring 6, limit dais 2 can be and 3 one-tenth disjunctor shapes of siphunculus, also can be fixedly mounted on the siphunculus 3.Can also be provided with scrobicular ring 7 at least 1 circle on the sleeve pipe 51,52, as shown in Figure 2,, play the effect of stiffening rib to strengthen the rigidity and the intensity of siphunculus.Interior scrobicular ring 7 also can be arranged to outer bulge loop 7, and just its rigidity and intensity are poorer slightly.
By after the above-mentioned connection, when water flowing or oil, the frictional force that the hydraulic pressure that produces will make seal ring overcome between itself and siphunculus and the tubing is pressed to limit dais, seal ring is owing to be subjected to the compressing of left and right sides pressure, add that seal ring has elasticity, seal ring can only be along its radial direction distortion, make the outer rim of seal ring get tighter tighter to the interior wall pressure of tubing, the inner edge of seal ring is also pressed tighter tightlyer to the periphery of siphunculus simultaneously, realized being connected sealing between the sleeve pipe of tubing and flange cover, and realize the sealing between the flange cover by sealing gasket and bolt between two flange plate and firmly is connected, thereby two tubing have been played extraordinary connection sealing and firmly acted on.Simultaneously, when having between the tubing when necessarily scratching dynamic deformation,, can adapt to distortion automatically, to keep the sealing between seal ring and siphunculus and the tubing because seal ring one side can the change of surplus position.Can make the elbow of several angle between the flange plate of flange cover and the sleeve pipe, angle changes when connecting to adapt to tubing.
