Abstract
The invention discloses a kind of multilayer net cover bellows, including ontology, ontology includes bellows, catch net and stiffening ring; catch net is sheathed on the outside of bellows; the both ends of bellows are provided with straight flange end, and stiffening ring is sheathed on the outside at straight flange end, with the associated part that is weldingly connected.Solid good heat insulating of the invention, efficiently solves displacement noise, substantially prolongs the multilayer water conservancy diversion compound type corrugated pipe of the service life of metal bellows.
Description
Technical field
The invention belongs to Bellows Technology fields, and in particular to a kind of multilayer net cover bellows.
Background technique
Used bellows is single or double layer pipe, is used in exhaustion system for automobile between engine and other connecting components
Damping and buffering the fracture failure of bellows, Er Qieyou have been resulted in due to the particularity of engine operating environments in a short time
Change in size between the internal wave and wave of bellows, produces corresponding noise, so that the row of six or more states is not achieved
Noise criteria requirement is put, in consideration of it, it is necessary to make improvement to traditional bellows.
Summary of the invention
To solve the deficiencies in the prior art, it the purpose of the present invention is to provide a kind of solid good heat insulating, efficiently solves
Displacement noise substantially prolongs the multilayer water conservancy diversion compound type corrugated pipe of the service life of metal bellows.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of multilayer net cover bellows, including ontology, ontology include bellows, catch net and stiffening ring, and catch net is sheathed on wave
The outside of line pipe, the both ends of bellows are provided with straight flange end, and stiffening ring is sheathed on the outside at straight flange end, with the correlation that is weldingly connected
Part.
Preferably, aforementioned ontology uses the one-pass molding of water expansion process.
More preferably, aforementioned stiffening ring and straight flange end is of same size.
It is highly preferred that previous corrugated pipe uses 4 layers of structure.
The invention has the beneficial effects that:
(1) common bellows is solved because intensity is inadequate and anti-fatigue performance difference leads to bellows initial failure phenomenon of rupture；
(2) more previous bellows increases multilayer in inside, effectively increases product strength and anti-fatigue performance, it is ensured that hose
It can be chronically at the state of free extension, hose early fracture failure phenomenon is avoided, extend the service life of product；
(3) can effectively solve the associated part initial failure being connected with the product brings exceeded alignment request running to show bellows
As the damage with foreign debris to bellows, the normal use of effective protection bellows.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the enlarged drawing in Fig. 1 at A.
The meaning of appended drawing reference in figure: 1. stiffening rings, 2. bellowss, 3. catch nets.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and 2, a kind of multilayer net cover bellows of the invention, including ontology, ontology include bellows, catch net
And stiffening ring, bellows use 4 layers of structure, catch net is sheathed on the outside of bellows, and the both ends of bellows are provided with straight flange end,
Stiffening ring is sheathed on the outside at straight flange end, with the associated part that is weldingly connected, stiffening ring and straight flange end it is of same size, ontology uses water
Expansion process one-pass molding.
The present invention has good antifatigue effect, and manufacture craft is formed using hydraulic pressure, air tight, water-tight, leakproofness
Can be good, separately because the product is four layers, there is certain insulating space between layers, Gu good heat insulating, diversion pipe internal structure
Unanimously, it can make to discharge air-flow even running, efficiently solve displacement noise, be able to satisfy the heat preservation of current six or more discharge standard of state
It is required that and noise requirements；Catch net energy effective protection foreign debris to collision and the other associated part initial failures of bellows and it is right
Bellows brings overproof running to use, and substantially prolongs the service life of metal bellows.
The present invention solves common bellows because intensity is inadequate and anti-fatigue performance difference causes bellows initial failure to be broken
Phenomenon；More previous bellows increases multilayer in inside, effectively increases product strength and anti-fatigue performance, it is ensured that hose energy
It is enough chronically at the state of free extension, hose early fracture failure phenomenon is avoided, extends the service life of product；It can be effective
Solve the phenomenon that associated part initial failure being connected with the product brings exceeded alignment request to operate bellows and foreign debris
Damage to bellows, the normal use of effective protection bellows.
The present invention is achieved by the following technical solutions: then ontology uses water expansion process by four kinds of pipe integrators
One-pass molding, then be made of bellows, catch net, stiffening ring, metal bellows uses 4 layers of structure, and both ends are formed with straight section, wave
Catch net is inserted in outside line pipe, both ends put on stiffening ring and are fixedly connected with therewith, are connected for any associated part weld afterwards.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
