Abstract
The invention belongs to the technical field of high-pressure conduit systems of airplanes and particularly relates to a bellows joint. The bellows joint overcomes the problems that a metal bellow expansion joint is heavy in weight and short in service life and has great leakage hidden dangers, and a bellows generates a push force when compressed to influence pipeline mounting in the prior art. The bellows joint is characterized in that two connecting pipes are welded at the two ends of a bellows respectively; two hinge rings are fixed on the two connecting pipes respectively; a universal ring is arranged between the two hinge rings; and the two hinge rings and the universal ring form a universal joint via a pin shaft. The joint has the characteristics of light weight and long service life, and can reduce the hidden dangers of pipeline leakage, the reliability and maintainability are improved, the push force generated by the bellows due to compression can be further eliminated, so that the joint has better practicability, is easy to popularize and apply and has a higher practical value.
Description
Technical field
The invention belongs to the technical field of airplane high-pressure guide pipe system, be specifically related to a kind of corrugated pipe connector.
Background technique
In airplane high-pressure guide pipe system, need to use compensator to compensate the Stress and displacement because temperature variation, alignment error and mechanical vibration etc. cause to high-pressure conduit, ensure reliability and the Security of high-pressure conduit system.Traditional corrugated compensation of pipeline device (corrugated expanding metal joint) does not generally possess self bears the function that bellows pressure produces thrust, exist and bring larger pressure thrust by after interior pressure to pipeline, the excessive weak link of extending inefficacy of bellows easily occurs in addition.Pressure-balancing type corrugated expanding metal joint possesses the thrust function of self bearing bellows pressure and producing, but needs to use drag link mechanism or straight tube mechanism and multiple bellows to carry out balancing the thrust of ripple pipe pressure generation; Easily there is the defect ruptured in drag link mechanism pull bar in vibration environment; Straight tube organization volume is large, and Heavy Weight, airplane high-pressure guide pipe system should not adopt.
In addition, corrugated expanding metal joint is applied on high-pressure conduit, mainly there is flange and the firm joint of Quick Release Hoop is many, has leakage hidden danger; Jointing and conventional metals corrugated expansion joint heavier-weight; Conventional metals corrugated expansion joint working life lower can not the longevity same with aircraft, add maintenance and the maintenance cost of aircraft; Need field sampling to manufacture conduit in pipeline manufacture process more, manufacturability is poor, increases manufacture cost.
Summary of the invention
The present invention in order to overcome prior art corrugated expanding metal joint Heavy Weight, life-span low, leak that hidden danger is large, bellows pressurized produces the problem that thrust affect pipeline installation, provide a kind of corrugated pipe connector, effectively can reduce the hidden danger of pipeline leakage, weight reduction, improve the life-span; And bellows pressurized generation thrust can also be eliminated.
The present invention adopts following technological scheme to realize:
A kind of corrugated pipe connector, two connecting tubes are welded at bellows two ends respectively, and two connecting tubes fix two swivel hooks respectively, arrange cardo ring between two swivel hooks, and two swivel hooks and cardo ring form universal joint by pinned connection.
Described bellows realizes sealing and compensate function.
Described bearing pin, swivel hook and cardo ring composition universal joint, realizes radially rotating, and angle compensation and elimination bellows pressure produce the function of thrust.
The present invention is used for airplane high-pressure guide pipe system and carries out the Stress and displacement that temperature variation, alignment error and mechanical vibration etc. cause and compensate, there is lightweight, that the life-span is long feature, the hidden danger of pipeline leakage can be reduced, improve reliability and maintenance, and bellows pressurized generation thrust can also be eliminated, therefore practicability is better, is easy to apply, has larger use value.This product can be widely used in the High Temperature High Pressure conduit of large aircraft, space flight, field of petrochemical industry, and marketing has a extensive future.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-connecting tube, 2-swivel hook, 3-cardo ring, 4-bearing pin, 5-bellows.
Embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
A kind of corrugated pipe connector, bellows 5 two ends are welded respectively two connecting tube 1, two connecting tubes 1 fix between two swivel hook 2, two swivel hooks 2 respectively and are arranged cardo ring 3, and two swivel hooks 2 and cardo ring 3 connect to form universal joint by bearing pin 4.
Advanced configuration form of the present invention, namely realizes radial angle compensate function, effectively reduces product weight again, in addition because bellows only bears angle displacement, reaches the requirement of life-span length.
Between swivel hook and bearing pin, carry out wear-resisting lubricated, reduce angle compensation moment, enhance the compensation ability of product, reduce the working stress of high-pressure conduit system.
Bearing pin, swivel hook and cardo ring composition universal joint, reduces the sudden change shearing stress compensated bellows, increases the fatigue life of product, and protection thin-wall corrugated tube should not cause mechanical deterioration in use and installation process.
Bearing pin, swivel hook and cardo ring composition universal joint, also possesses and self bears the function that bellows pressure produces thrust, eliminate the impact on high-pressure conduit.
