Abstract
The utility model relates to a buffer multiple-connection pressure-balancing corrugated expansion joint, comprising three corrugated pipes, wherein, the effective area of a larger corrugated pipe is equal to the sum of the effective areas of two small corrugated pipes; the sizes of two small corrugated pipes are different. Each of two end connecting pipes does not have a nourishing end plate; the extending end of the connecting pipe is connected with the corrugated pipes through a T-shaped ribbed slab. Compared with a prior straight pipe pressure-balancing expansion joint and a straight pipe bypass type pressure-balancing expansion joint, the fabrication process of the utility model is easy to be guaranteed, the utility model is especially suitable for a pipeline system with complex trend, high-altitude laying, large span, large caliber, high flow rate of medium, large required compensation, small flow resistance and high flexural resistance requirement.
Description
The utility model relates to a kind of buffering pressure-balancing type FlexbleJoint in parallel, belongs to the line device technical field.
FlexbleJoint is extensively with the delivery line of gas, liquid medium in the systems such as drystoneization, metallurgy, electric power, heat supply network, to absorb the end thrust that the pipeline thermal distortion that caused by temperature variation and balance are caused by interior pressure.The single corrugated expansion joint of general straight-through type can only absorb thermal distortion and can not balancing axial thrust.Usually adopt straight pipe pressure-equalizing type compensator at present, form with upper connecting rod etc. by two small corrugated pipes and big bellows and three, though can absorb thermal distortion and balance end thrust, but two small corrugated pipes must be big or small just the same, the manufacture process requirement height, and bending resistance and reliability are relatively poor, and volume is big, and the compensation elastic reaction is big.Other has a kind of straight tube bypass type pressure-balancing type compensator, than the former remarkable progress is arranged, but has the cecum plate to exist in the straight tube, and is higher as velocity of medium, then can produce shock and vibration.
The purpose of this utility model is to overcome deficiency of the prior art, carry arch a kind of can absorb thermal distortion also can balancing axial thrust, and easy to manufacture, good reliability is avoided the buffering pressure-balancing type FlexbleJoint in parallel of impact shock.
The technical solution of the utility model is: cushion pressure-balancing type FlexbleJoint in parallel and be made of adapter, overcoat, ring flat-plate, end socket and two less work bellowss, a bigger balance bellows.It is characterized in that balance bellows and the parallel connection of a work bellows, both constitute air cavity between the tube wall, another work bellows one end with take over into sealed type and be connected, the other end becomes sealed type to be connected by ring flat-plate and overcoat, and balance bellows useful area equals two work bellows useful area sums.During work, two work bellowss are subjected to interior pressure, are stretching trend, and the balance bellows is subjected to external pressure, is compression trend.Thrust that both cause and pulling force act on outer putting simultaneously, and equal and opposite in direction, and direction is opposite, is able to balance.Two work bellows sizes can be the same, also can be different, guarantee easily during manufacturing.Overcoat and ring flat-plate intensity height, resistance to bending is strong, good reliability.
Above-mentioned air cavity links to each other with two pipe nipples by T shape gusset, and T shape gusset intensity is good, connects reliably, saves steel pipe, and cost is low.By the no cecum of pipe, be not subjected to MEDIA FLOW to impact friction.Air cavity only communicates with atmosphere by connecting tube, makes the bellows low voltage side remain barometric pressure, does not increase deformation resistance, and is stable and reliable for performance.Between ring flat-plate that links to each other with overcoat one end and the T shape gusset space is arranged, but slide relative helps compensator and absorbs thermal distortion.
Because said structure feature, the utility model are made easily, good reliability, can effectively absorb thermal distortion and balance end thrust, avoid impact shock, be particularly useful for moving towards complicated, high-altitude and lay big span, heavy caliber, the velocity of medium height needs large compensation, and flow resistance is little, flex resistance requires high, should not establish the pipeline system of main anchor.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
As figure, balance bellows 5 and 6 parallel connections of work bellows constitute air cavity 10 between both tube walls, and this air cavity only communicates with atmosphere by connecting tube 9, links to each other with 8 with two pipe nipples 1 by T shape gusset 3.Another work bellows 2 one ends weld with taking over 1 one-tenth sealed type, and the other end is by ring flat-plate 11 and 4 one-tenth sealed types welding of overcoat.Overcoat 4 is by 8 one-tenth sealed types welding of end socket 7 and adapter.Between ring flat-plate 11 and the T shape gusset 3 space 12 is arranged.The latus rectum of balance bellows 5 is 550mm, and workpiece bellows 2 and 6 latus rectum are respectively 400mm and 350mm.
