Abstract

The utility model relates to a metal bellow for connecting a stepped pipeline, characterized in comprising a flange to connect a large diameter pipeline, a flange to connect a small diameter pipeline and a tower metal bellow with the diameter gradually varying from large to small. Plural corrugations of the bellow are set in the middle section thereof and the flanges are respectively welded at the big end and the small end of the bellow. The utility model is not only suitable for a stepped pipeline system of large displacement deformation compensation, but also can work under high temperature of the pipeline system transmission and high pressure.

Description

The metal bellows that connects tapered pipeline
Technical field
The utility model relates to a kind of bellows that connects sealed mode bit shift compensation pipeline, is specially adapted to connect the metal bellows of the big displacement deformation compensation of airtight hydraulic pressure tapered pipeline system.
Background technique
At present, in the pipe-line system of sealed mode bit shift compensation, adopt isodiametric cylindrical ripple pipe connected pipe road, two ends system usually.When cylindrical ripple tube and tube road system was connected, its two ends adopted the flange plate of identical latus rectum to be connected with pipeline respectively.But this columniform bellows is only applicable to the identical pipe-line system of caliber, the big bit shift compensation of sealed mode system for the tapered pipeline system, usually adopt flexible pipe or nonmetal (rubber pipe) turriform bellows to be connected with cylindrical ripple pipe, by flexible pipe or the transition of nonmetal (rubber pipe) turriform bellows, connect the pipeline of reducing.Because plastic flexible pipe and nonmetal (rubber pipe) turriform bellows bear high temperature, high pressure ability, can not be used for temperature height, telescoped line system that pressure is big.
Summary of the invention
The purpose of this utility model provides a kind of turriform bellows that connects tapered pipeline, and it is not only applicable to big displacement deformation and compensates the tapered pipeline system, and can bear the high temperature of pipe-line system transmission and the medium of high pressure.
The purpose of this utility model is achieved in that
The metal bellows that connects tapered pipeline, comprise the flange that connects big-diameter pipeline, connect the flange of small-caliber pipeline and the turriform bellows of reducing gradually from big to small, the stage casing of the described bellows of some ripples on the bellows, flange is weldingly fixed on the big end and the small end of bellows respectively.
Adopted such scheme, bellows is the turriform bellows of reducing gradually from big to small, because the caliber at bellows two ends is unequal, therefore can connect the tapered pipeline system.Metal bellows can bear the medium of pipeline transmission high temperature and high pressure, guarantees the reliability of pipe-line system sealing transmission medium.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the I portion enlarged view among Fig. 1;
Fig. 3 is the P portion enlarged view among Fig. 1;
Fig. 4 is the Q portion enlarged view among Fig. 1.
Embodiment
Referring to Fig. 1 to Fig. 4, the metal bellows of connection tapered pipeline of the present utility model comprises the flange 1 that connects big-diameter pipeline, flange 2 and the bellows 3 that connects small-caliber pipeline, and flange 1,2 and bellows all adopt metallic material to make.Bellows 3 is the turriform bellows of reducing gradually from big to small, makes the caliber of bellows 3 one ends greater than the caliber of the other end.Several ripples of bellows are positioned at the stage casing of this bellows, and bellows adopts the hydraulic way moulding, for ease of shaped by fluid pressure ripple is arranged, and adopt the thin pipe of tube wall to make the pressure-bearing body.The tube wall of bellows can be one or more layers, in use, can determine wave number, wall thickness and tube wall layer number, the tapering cone angle size of turriform bellows according to the pressure and the temperature level difference of the reducer pipe medium of flowing through, when tube wall was multilayer, its interlayer was fixing by welding.The number of plies of present embodiment bellows is two-layer.The big end of bellows 3 and flange 1 welding are fixing, and the small end of bellows and flange 2 welding are fixing. Flange 1,2 and bellows 3 all weld fixing by the argon arc welding mode.Flange 1,2 axially connects end face and is respectively equipped with circular groove 1a, 2a, and circular groove 1a, 2a are used to install seal ring, and its degree of depth all has mounting hole 1b, 2b less than the thickness of seal ring on the end face of flange 1,2.
When assembling with bellows described in the utility model and tapered pipeline, seal washer is installed among the circular groove 1a of the flange 1 that connects big-diameter pipeline, the mounting hole that passes flange 1 and big-diameter pipeline by bolt is connected with nut thread, with flange 1 and big-diameter pipeline locking.Seal washer is installed among the circular groove 2a of the flange 2 that connects small-caliber pipeline, the mounting hole that passes flange 2 and small-caliber pipeline by bolt is connected with nut thread, with flange and small-caliber pipeline locking.When the reducing system carries out work, the high temperature of system transmissions, the liquid of high pressure (gas) working medium carry out airtight transmission by the turriform metal bellows, simultaneously, utilize the anticorrosive property and the turriform metal bellows of turriform metal bellows to be subjected to the elongation of influence of temperature change and pressure effect generation and to shorten the self compensation function that changes, with stability and the reliability of guaranteeing system works.

Claims (3)
