Abstract
The utility model belongs to a pipe connecting piece, mainly relates to a pressure-balancing type expansion joint with a novel structure for a bent pipe. The expansion joint comprises two groups of operation corrugated pipes 7, a balancing corrugated pipe 14, end connecting pipes 3 at two ends, a spring device, a compound universal hinge plate and a proportion connecting-rod device 8, wherein the spring device is an external hanging type, that is, one end of the spring device is connected with a flatform bracket 10, and the other end thereof device is connected with the end connecting pipe 3 at the inlet of a smoke machine through an end-part annular plate. The expansion joint solves the problems of deformation of the end connecting pipes, incongruous deformation of the corrugated pipes, and vibration of an intermediate pipe of the expansion joint in the prior art, and improves the load-carrying capability of a smoke machine.
Description
Technical field
The utility model belongs to pipe connector, relates generally to a kind of bend pipe pressure balance type expansion joint of new structure.
Background technique
Generally select the pressure-balancing type expansion joint for use on domestic each oil refining enterprise catalytic cracking unit energy-recuperation system key equipment-cigarette machine outlet conduit at present, be used to absorb the length travel of cigarette machine outlet, guarantee the force request and the safe operation of cigarette machine equipment.Existing pressure-balancing type expansion joint has two kinds, and a kind of pressure-balancing type expansion joint is made up of the hinge plate that is symmetrically distributed in the expansion joint both sides, bellows, adapter, threeway etc.Bellows is used to absorb thermal walking, and the two ends of hinge plate link to each other with taking over, and hinge plate bears the pressure thrust that bellows produces, and this power is reached in the adapter.In use there are the following problems for this type expansion joint: 1, local deformation easily takes place in the adapter that links to each other with hinge plate on the expansion joint, influences the safe handling of expansion joint; 2, because this type expansion joint weight is heavier, though be provided with supporting at expansion joint three-way straight pipe place, the expansion joint threeway still can produce additional force to the cigarette machine equipment with the weight of bottom, and is stressed unfavorable to the cigarette machine; 3, two groups of work bellowss are easy to generate the distortion inequality; 4, intervalve is easy to generate vibration.
Another kind of pressure-balancing type expansion joint is made up of adapter, stiffening plate, floor, bellows, guide sleeve, pull bar, adjusting nut, spring, universal joint, middle adapter, ratio connecting rod and threeway etc.Utilize the stiffening plate of taking over two ends to fixedly install four segmented pull bars, every segmented pull bar is in aggregates by the universal joint connection, and every pull bar is provided with guide sleeve.This type expansion joint guarantees that by four pull bars and universal joint are set it can absorb lateral displacement, prevents the local deformation of taking over by stiffening plate and floor are set on pipe nipple; By spring is set the weight of whole expansion joint is delivered on the support by threeway, though this type expansion joint makes moderate progress on structure and performance, in use still need to add spring and hang the vibration problem that solves expansion joint work bellows intervalve.
Summary of the invention
The utility model proposes a kind of bend pipe pressure balance type expansion joint of new structure, its purpose is to solve that the distortion of expansion joint pipe nipple in the prior art, bellows distortion are inharmonious, the intervalve vibration, improve the problem such as stressed of cigarette machine equipment.
The technical solution adopted in the utility model is: a kind of bend pipe pressure balance type expansion joint of new structure, the pipe nipple and the spring assembly that mainly comprise two groups of work bellowss, balance bellows, two ends are provided with universal double-jointed hinge plate, ratio connecting rod means simultaneously; Wherein said universal double-jointed hinge plate is made up of the short hinge plate, the band andgudgeon carrier bar that connect by crosshead, and universal double-jointed hinge plate is fixed by the pipe nipple at expansion joint two ends; Described ratio connecting rod means is arranged between two groups of work bellowss, and the one end links by end ring flat-plate and pipe nipple, and the other end and threeway link; Described spring assembly adopts external hanging type, and promptly one end and platform support link, and the other end connects with the pipe nipple at flue gas turbine inlet place by the end ring flat-plate.
Described two groups of work bellowss, balance bellows adopt the thin-walled double layer construction.
The shared work guide shell of described two groups of work bellowss.
The bend pipe pressure balance type expansion joint of a kind of new structure that the utility model proposes has solved preferably that expansion joint pipe nipple distortion in the prior art, bellows distortion are inharmonious, the intervalve vibration, improve the problem such as stressed of cigarette machine equipment.
Description of drawings
Accompanying drawing 1 is a model utility bend pipe pressure balance type expansion joint tectonic maps.
Among the figure: 1, end ring flat-plate, 2, riser, 3, pipe nipple, 4, spring, 5, the operating wave guide shell, 6, short hinge plate, 7, work bellows, 8, the ratio connecting rod means, 9, intervalve, 10, platform support, 11, crosshead, 12, threeway, 13, band andgudgeon carrier bar, 14, the balance bellows, 15, the balance wave guide shell, 16, dome head, 17, the shipment bar.
Embodiment
The embodiment who provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, a kind of bend pipe pressure balance type expansion joint of new structure mainly comprises the pipe nipple 3 and the spring assembly at two groups of work bellowss 7, balance bellows 14, two ends being provided with universal double-jointed hinge plate and ratio connecting rod means 8 simultaneously; Wherein said universal double-jointed hinge plate connects to form by short hinge plate 6, band andgudgeon carrier bar 13 and by crosshead 11, and universal double-jointed hinge plate is fixing with pipe nipple 3 respectively by the riser 2 at expansion joint two ends; Pipe nipple 3 adopts the dual collar plate reinforced structure, can prevent effectively that pipe nipple from losing the circle distortion; Described ratio connecting rod means 8 is arranged between two groups of work bellowss 7, and the one end links by end ring flat-plate 1 and pipe nipple 3, and the other end and threeway 12 link; The two ends of threeway connect with work bellows 7, balance bellows 14 respectively; When the displacement in the external world acts in pipe nipple 3 and/or the threeway 12, absorb by the compression of two groups of work bellowss 7 and the stretching of deflection and balance bellows 14, compound hinge plate structure guarantees the absorption of displacement and the pressure thrust that the constraint bellows produces, ratio connecting rod means 8 can guarantee that not only two groups of work bellows 7 compatibilities of deformation are synchronous simultaneously, and can bear the weight of intervalve 9 between two groups of work bellowss, it is delivered in pipe nipple 3 and the threeway 12, helps reducing the vibration of intervalve; Described spring assembly adopts external hanging type, be that one end and platform support 10 link, the other end connects with the pipe nipple 3 of flue gas turbine inlet end by end ring flat-plate 1, by spring 4 is carried out suitable pre-stretching, can be with the work bellows of threeway below 12, pipe nipple, hinge plate, the reducing of connecting rod means and the outlet of its underpart cigarette machine is taken over the weight pull-up and is delivered on the platform support 10, because the compressible and tensility of spring 4, it can not influence the function that expansion joint absorbs displacement, has so satisfied the harsh stressed and thermal walking compensation requirement of cigarette machine equipment and outlet conduit thereof.Described work bellows 7, balance bellows 14 adopt the thin-walled double layer construction, two groups of work bellows 7 shared work guide shells 5.
