Plastic corrugated pipe does not have establishment aramid fiber layer, and the pipe wall is thinner, and it is less to connect load, and the installation is dismantled simpler and more directly, and leakproofness and stability are also higher, and the ripple section with the combination of fluorescent lamp section both can make the arbitrary bending of the plastic corrugated pipe installation of being convenient for, the effective noise in the reduction work again.
Description
Technical field
This utility model belongs to turbocharged engine technical field, is specifically related to a kind of turbine relief tube.
Background technology
Turbocharged engine refers to be equipped with the electromotor of turbocharger.A kind of air of turbocharger
Compressor, increases air inflow by compressed air.It is that the waste gas inertia impulsive force utilizing electromotor to discharge is to promote turbine to increase
The turbine of depressor, turbine drives again coaxial impeller, the air that impeller force feed is sent here by air filter pipeline, is allowed to supercharging and enters
Enter cylinder.When engine speed speeds, the waste gas velocity of discharge and secondary speed the most synchronize speed, and impeller just compresses more air
Entering cylinder, the pressure of air and density and increase the more fuel that can burn, corresponding increase fuel quantity starts with adjusting
The rotating speed of machine, it is possible to increase the output of electromotor.The waste gas of High Temperature High Pressure flows out through pressure release from turbocharger
Being discharged by relief tube after valve, the relief tube that current each main engine plants use is mainly resistant to elevated temperatures HT-AEM rubber tube again.
Owing to rubber itself is softer, crushing resistance is poor, wants to meet the pressure of turbo charge system for improving crushing resistance
Ask, in the tube wall of the relief tube of quality of rubber materials, need to add establishment aramid layers, the extrusion of the relief tube of this band establishment aramid layers
Technics comparing is complicated, in addition it is also necessary to twice sulfuration is shaped, and not only manufacturing cost is higher, and the feature of environmental protection is poor；And this rubber tube tube wall
Thicker, weight is big, is the most generally processed as smooth pipe, can produce bigger stress, be installed between electromotor and vehicle frame during bending
Can occupy larger space, the load that two ends connect is the biggest, and the sealing of junction and stability are easily by high pressure, the environment of vibration
Impact, need the extra devices such as the loaded down with trivial details metal clip of structure that increase to fix, this causes the installation of relief tube loaded down with trivial details, time-consuming
Arduously.
Utility model content
Therefore, this utility model is thicker for the rubber relief tube tube wall of bright finish in prior art, and the load of connection is relatively big,
Sealing and the stability of junction are the most affected by environment, install loaded down with trivial details technical problem, it is therefore intended that provide a kind of tube wall relatively
Thin, connect load less, sealing and stability are higher, turbine relief tube easy for installation.
Turbine relief tube of the present utility model includes that a plastic film capicitor, described plastic film capicitor include some straight bright finish
Section and some bellows segment being connected between described bright finish section.
Described plastic film capicitor is without establishment aramid layers, and tube wall is relatively thin, connects load less, when waste gas is by described plastics ripple
During stricture of vagina pipe, if not having described bright finish section easily to produce noise, and the combination of described bellows segment and described light pipe segment both can make institute
State plastic film capicitor arbitrarily to bend and be easily installed, can effectively reduce again the noise in work.
In a preferred embodiment of the present utility model, it also includes two snap joints, and snap joint described in two is inserted described
Plastic film capicitor two ends port forms interference fit.Sealing, bonding strength and the anti-seismic performance of this attachment structure itself are higher,
Metal clip without using structure loaded down with trivial details is fixed.
Further, described plastic film capicitor two ends port peripheral has been locked an outer reinforcing sleeve respectively, described outer reinforcing sleeve
Simple in construction, easy for installation, can further improve the sealing of connection, bonding strength and anti-seismic performance.
In preferred embodiments more of the present utility model, described plastic film capicitor is resistant to elevated temperatures PPA material extrusion molding
Integrative-structure.
Positive progressive effect of the present utility model is:
In described turbine relief tube assembly of the present utility model, the crushing resistance of described plastic film capicitor own is higher, without establishment
Aramid layers, under identical pressure functional requirement, the tube wall of described plastic film capicitor is thinner, and weight only has the 1/4-1/3 of rubber tube,
It is more conducive to automotive light weight technology design.Described plastic ripple tube wall is relatively thin adds that having ripple struction can arbitrarily bend, during bending
Stress is little, connects load relatively low, higher with the sealing of the interference fit of described snap joint, bonding strength, it is not necessary to structure is numerous
Trivial metal clip is fixed, and this makes the installing/dismounting of described turbine relief tube simpler and more direct, can immediately install, immediately tear open
Unload.And the setting of described outer reinforcing sleeve, sealing, bonding strength and the anti-seismic performance of described turbine relief tube can be made to carry further
Height, long-term high pressure, vibration work in reliability higher.Extrusion process simple nothing when the most described plastic film capicitor manufactures
Need sulfuration, more economically environmental protection.

Detailed description of the invention
Below with reference to specific embodiments and the drawings, turbine relief tube of the present utility model is further described.
Fig. 1 show the turbine relief tube of a preferred embodiment of the present utility model, and it includes plastic film capicitor 101, two
Individual straight type snap joint 102 and two outer reinforcing sleeves 103.
As shown in Figures 2 and 3, plastic film capicitor 101 is the integrative-structure of resistant to elevated temperatures PPA material extrusion molding, including four
Bright finish section 101a of Duan Zhi and three sections of bellows segment 101b that can arbitrarily bend being connected between bright finish section 101a.
Straight type snap joint 102 one end is that the outer wall public access mouth 102a with barb, public access mouth 102a insert plastic ripple
Pipe 101 two ends port forms interference fit, and two outer reinforcing sleeves 103 are locked on outside the port of plastic film capicitor 101 two ends respectively
Enclosing, outer reinforcing sleeve 103 material is macromolecular material or metal, can make public access mouth 102a and plastic film capicitor 101 two ends port
Between sealing, bonding strength and shock resistance be greatly reinforced, even if also will not under long-term high pressure, high temperature and Vibration Condition
There is the risk come off.
The other end of straight type snap joint 102 is maternal interface 102b, for being connected with the joint of relief valve, and maternal interface 102b
Sidewall be provided with horizontal clip slot and be equipped with a metal clip 102c, as shown in Figures 4 and 5, metal clip 102c have
Having two can be inserted into clip slot and lay respectively at the jig arm of maternal interface 102b inner chamber both sides, maternal interface 102b side is additionally provided with anti-rotation
Draw-in groove 102d, inserts maternal interface 102b by the joint of relief valve when installing with this, and being then inserted into metal clip 102c can press from both sides
Fasten, can immediately install, immediately dismantle, facilitate simple and direct, and turbine relief tube assembly can be entered one by anti-rotation draw-in groove 102d
Step is fixed on the adjacent miscellaneous parts such as electromotor, improves the stability of turbine relief tube assembly further.
