Description
Technical field
The utility model is applicable to aerospace vehicle engine bleed pipe-line system and other pipe-line system that need to compensate.
Background technique
The effect of compensation of pipeline device mainly is owing to expanding with heat and contract with cold and pipeline axial displacement compensation and the radial angle compensation that causes being installed for pipeline.
At present both at home and abroad the compensation of pipeline device that adopts of the High Temperature High Pressure pipeline on the aircraft is generally: 1. with the metal bellows of outside link formula, have axial compression and stretch compensation function, has simultaneously the radial angle compensate function, but the angle compensation ability is less, generally be not more than 5 °, its outside link has 3~4 usually, and its overall sizes is larger, weight is larger, has limited its angle compensation ability; 2. the metal bellows of interior hinge is assembled by 9 kinds of 12 spare parts combinations such as bellows, convex joint, female fitting, joints sleeve, stiffening ring, hinged overcoat, hinged kink, hinged inner sleeve, inner sleeve, its volume less but complex structure, install to cooperate and require height, assembly technology requires high, and its weight and manufacture cost are also high; 3. universal joint, it only has the angle compensation function; 4. have the compensator of tensile and compress compensation, but do not have the angle compensation function;
The model utility content
The purpose of this utility model is: a kind of volume is little, and is simple in structure, and lightweight compensation of pipeline device not only has axial compression and stretch compensation function, also has the angle compensation function, can satisfy simultaneously the multiple compensation requirement of pipe-line system.
The technical solution of the utility model is: the utility model is a kind of compensation of pipeline device, described compensation of pipeline device is comprised of pipe joint I 1, bellows 2, pull bar 3, pipe joint II 4, plug screw 5, support I 6, support II 7 and nut 8, its support I 6 is comprised of axle sleeve and outside support blade, axle sleeve one stomidium directly is slightly larger than the bar footpath of pull bar 3, this end inboard is a ball-and-socket, and the other end of axle sleeve is screw thread; Support II 7 is comprised of axle sleeve and outside support blade, and the aperture of axle sleeve is slightly larger than the bar footpath of pull bar 3; Pull bar 3 one ends are spherical structure, the diameter of spherical structure is greater than the pull bar diameter, spherical structure is fixed in the ball-and-socket of compensation of pipeline device one end support I 6, the other end of pull bar 3 passes behind the center hole of support II 7 axle sleeves fixing with nut 8, pull bar 3 can slide along axis in support II 7 center holes, and plug screw 5 is pressed on spherical structure one end of pull bar 3 in the ball-and-socket of support I 6; Pipe joint I 1, pipe joint II 4 are with the straight-run of pipe section; Bellows 2 is elastic bellows, and two ends are connected with pipe joint I 1, pipe joint II 4 outer surfaces respectively.
The utility model has the advantages that: the utility model adopts draw-in bar formula metal bellows structure, it is large to have abandoned outside link formula compensation of pipeline device overall sizes, the shortcoming of Heavy Weight, interior hinge formula compensation of pipeline device complex structure, machining accuracy and the demanding shortcoming of assembly technology have been abandoned, combine the advantage of Typical Foreign compensation of pipeline device, be a multi-functional formula compensation of pipeline device, not only have little, simple in structure, the lightweight characteristics of overall sizes, and its angle compensation ability can improve significantly.
