Abstract
The utility model discloses a multilayer metal corrugated pipe, which comprises a fixed flange, a reinforced pipe, a corrugated pipe, a universal flange, a check ring and an asbestos pad; the method is characterized in that: the metal corrugated pipe adopts a 4-layer structure, straight edge sections are arranged at two ends of the metal corrugated pipe, the reinforcing pipe is inserted into the corrugated pipe and fixedly connected with the corrugated pipe, the fixed flange is welded with a port at one end of the corrugated pipe, the universal flange is sleeved at the other end of the corrugated pipe, and the check ring is welded with the port of the corrugated pipe; the asbestos pad is adhered to the end face of the retainer ring and connected with the retainer ring. The advantages are that: compared with the traditional corrugated pipe, the corrugated pipe has the advantages that multiple layers are added inside the corrugated pipe, the product strength and the fatigue resistance are effectively improved, the flexible pipe can be ensured to be in a freely telescopic state for a long time, the phenomenon of early fracture and failure of the flexible pipe is avoided, and the service life of equipment is prolonged.
Description
Technical field
The utility model relates to a kind of bellows, and especially a kind of multiple layer metal bellows belongs to the water conservancy diversion energy saving device in the vent systems.
Background technique
At present, used bellows is individual layer or bilayer, is used for damping and buffering between vent systems motor and other connected elements.Owing to the particularity of engine operation environment, just caused the fracture failure of bellows in a short time.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, a kind of multiple layer metal bellows is provided, this multiple layer metal bellows has good antifatigue effect, good seal performance, this product is one does not have the connecting part, middle gapless whole bellows, and carbon distribution and external dust can't retain, guarantee that this product normally uses, and has prolonged the working life of metal bellows greatly.
The utility model is achieved through the following technical solutions: a kind of multiple layer metal bellows, form by fastening flange, reinforcement tube, bellows, universal flange, back-up ring.It is characterized in that: metal bellows adopts 4 layers of structure, two ends are shaped on straight section, and reinforcement tube is inserted in the bellows and is connected mutually with it, the port welding of fastening flange and bellows one end, the other end at bellows is set with universal flange, the port welding of back-up ring and bellows.
Advantage of the present invention is:
1. solve bellows and cause bellows early failue phenomenon of rupture because of insufficient strength and anti-fatigue performance difference.
2. bellows has increased multilayer in inside more in the past, has increased product strength and anti-fatigue performance effectively, guarantees that flexible pipe can be in the state that freely stretches for a long time, avoids flexible pipe early fracture failure phenomenon, has prolonged the working life of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged view of A.
Among the figure, 1. fastening flange, 2. bellows, 3. universal flange, 4. back-up ring, 5. asbestos packing, 6. reinforcement tube.
Embodiment
As shown in Figure 1 and Figure 2, multiple layer metal bellows of the present utility model is made up of fastening flange 1, reinforcement tube 6, bellows 2, universal flange 3, back-up ring 4, asbestos packing 5.Metal bellows 2 adopts 4 layers of structure, two ends are shaped on straight section, and reinforcement tube 6 is inserted in the bellows 2 and is connected mutually with it, and fastening flange 1 welds with the port of bellows 2 one ends, the other end at bellows 2 is set with universal flange 3, and back-up ring 4 welds with the port of bellows 3.Asbestos packing 5 sticks on the end face of back-up ring 4, and is attached thereto and connects.
