Abstract
The utility model relates to a pressure balance type pipeline compensator, in particular to a pressure balance type pipeline compensator for a high-pressure guide pipe system of an air plane and solves the problems that in the prior art, a pull rod of the conventional pull rod type pressure balance type metal bellow expansion joint compensator is high in bending stress during radial mounting and working displacement, and is easy to break in a vibration environment. The pressure balance type pipeline compensator further comprises a spherical nut, a conical gasket, a pull rod, a spherical bearing and a nut, wherein a bottom cover at one end part of a balance bellow component outwards extends to form the spherical bearing; an epitaxial opening is formed in a front-end flange at one end part of a working bellow component; one end the pull rod is fixedly hinged to the spherical bearing through the nut, and the other end of the pull rod penetrates through the front-end flange and is hinged to the spherical nut and the conical gasket. The pressure balance type pipeline compensator has the characteristics of capacity of eliminating thrust generated by a bellow under pressure, large compensation amount and long service life, and is suitable for compensation in various forms such as axial compensation, radial compensation and angle compensation. Therefore, the pressure balance type pipeline compensator is higher in practicability and easy to popularize and apply, and has a higher practicable value.
Description
Technical field
The utility model relates to a kind of pressure-balancing type compensation of pipeline device, especially a kind of pressure-balancing type compensation of pipeline device for aircraft high-pressure conduit system.
Background technique
In aircraft high-pressure conduit system, need to use the compensator Stress and displacement that compensation causes due to temperature variation, alignment error and mechanical vibration etc. to high-pressure conduit, ensure reliability and the Security of high-pressure conduit system.Traditional pressure-balancing type corrugated expanding metal joint possesses the thrust function of self bearing the generation of bellows pressure, need to use drag link mechanism or straight tube mechanism and bellows to carry out the thrust that balance ripple pipe pressure produces, straight tube mechanism volume is large, Heavy Weight, aircraft high-pressure conduit system should not adopt; And drag link mechanism is under larger radial compensation displacement, flexural stress is larger, and in vibration environment, pull bar exists the hidden danger that fracture easily occurs, and is not suitable for radially installation and work shift compensation situation that existence is larger.
Summary of the invention
When the utility model compensates radially installation and work shift in order to overcome prior art pull-rod type pressure-balancing type corrugated expanding metal joint, pull bar flexural stress is large, easily in vibration environment, there is the problem of pull bar fracture, a kind of pressure-balancing type compensation of pipeline device is provided, can effectively improve pull bar stress, increase the radially installation compensation rate of product, improve the life-span; And can also eliminate bellows pressurized generation thrust.
The utility model adopts following technological scheme to realize:
Pressure-balancing type compensation of pipeline device, comprise work bellows component, balance bellows component, elbow, straight connector, work bellows component and straight connector are welded to connect, balance bellows component and elbow are welded to connect, characterized by further comprising Ball faced nut, taper faced washer, pull bar, spherical bearing, nut, balance bellows component end bottom extension mounting spherical bearing, work bellows component end front end flange extension perforate, one end of pull bar is fixed with spherical bearing hinged by nut, it is hinged that the other end passes front end flange and Ball faced nut and taper faced washer.
Described work bellows component is realized compensate function, and balance bellows component and Ball faced nut, taper faced washer, pull bar, spherical bearing, special nut are realized and eliminated pull bar, eliminate the function of bellows pressure generation thrust.The utility model can be realized pull bar and rotate in the time of installation and working state radial compensation, improves the stress phase of installation and the work compensation of drag link mechanism.
The utility model pressure-balancing type compensation of pipeline device carries out for aircraft high-pressure conduit system the Stress and displacement compensation that temperature variation, alignment error and mechanical vibration etc. cause, have and can eliminate bellows pressurized and produce the feature that thrust, compensation rate are large, the life-span is long, and be applicable to axially, radially, the compensation of angle various ways, therefore practicability is better, be easy to apply, there is 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.

Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described further.
Pressure-balancing type compensation of pipeline device, comprise work bellows component 3, balance bellows component 1, elbow 2, straight connector 4, work bellows component 3 is welded to connect with straight connector 4, balance bellows component 1 is welded to connect with elbow 2, also comprise Ball faced nut 5, taper faced washer 6, pull bar 7, spherical bearing 8, nut 9, balance bellows component 1 end bottom extension mounting spherical bearing 8, the 3 end front end flange extension perforates of work bellows component, one end of pull bar 7 is fixing hinged with spherical bearing 8 by nut 9, it is hinged that the other end passes front end flange and Ball faced nut 5 and taper faced washer 6.
Advanced bar jointing structure form of the present utility model, realized large radially with angle compensation function, effectively reduce again the compensation stress of pull bar, can adapt to harsher vibration environment and larger compensation rate, and improve life of product.
Pull bar and spherical bearing are hinged, and the other end and Ball faced nut and taper faced washer are hinged, can in the time of installation and working state radial compensation, realize pull bar and rotate, and improve the stress phase of installation and the work compensation of drag link mechanism.
The combination of balance bellows component and Ball faced nut, taper faced washer, pull bar, spherical bearing, special nut, possesses the function of self bearing bellows pressure generation thrust, has eliminated the impact on high-pressure conduit.
