Abstract
The utility model relates to an external pressure balance corrosion-proof corrugated compensator, which is characterized in that the sizes of two corrugated pipe are consistent; inner cavities are both communicated with the atmospheric air; a water dredging port is arranged on an outer cover. When in use, two corrugated pipes are both subjected to the external pressure; the columnar unstability can not be generated. The inner cavity can not contact with medium; the harmful raffinate which can cause the stress etching of a corrugated pipe can not be accumulated in the static state; the service life can be lengthened. The water dredging port on the outer cover can in time discharge the accumulative liquid in the cover. The utility model not only can absorb the heat deformation and balance the axial thrust but also has the anticorrosion property, the utility model is especially suitable for the pipeline system for conveying the medium containing much chloridion.
Description
The utility model relates to a kind of external-compression type pressure balance corrosion-proof type FlexbleJoint, belongs to the line device technical field.
Compensator is widely used in the delivery line of gas, liquid medium in the systems such as petrochemical industry, metallurgy, building, 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.General straight-through type corrugated expansion joint can only absorb thermal distortion, and can not balancing axial thrust.The someone has invented a kind of novel bypass type pressure-balancing type compensator at present, during work, and two bellowss, one is subjected to external pressure, and one is subjected to interior pressure, and the internal force that both cause acts on the coat simultaneously, and equal and opposite in direction, and direction is opposite, is able to balance.Thereby can absorb thermal distortion effectively, and end thrust can not passed to pipeline system.But be rich in the pipe-line system of chlorion medium, because the bellows that chlorion is pressed in to stainless affinity interaction, being subjected to for conveying, when static, meeting is accumulated because of chlorion water, causes the stress corrosion cracking (SCC) of corrugated stainless steel tubing, scrap in advance, obvious above-mentioned balance type compensator is no longer suitable.And the bellows of pressing in being subjected to tends to produce the column unstability under certain pressure, also influence product performance.
The purpose of this utility model is to overcome the deficiency of existing compensator, provides a kind of and can effectively absorb thermal distortion, and balancing axial thrust again can etch-proof external-compression type pressure balance corrosion-proof type compensator.
The technical solution of the utility model is: external-compression type pressure balance corrosion-proof type FlexbleJoint is made up of left side adapter, the right bellows of taking over, work, balance bellows, outer cover, ring flat-plate, end socket main member.Two bellows sizes are consistent, and two relative ends of bellows are all taken over into sealed type with a left side and are connected, and their the other end becomes sealed type to be connected with the two ends of outer cover respectively by ring flat-plate or right the adapter with ring flat-plate, and the inner chamber of two bellowss all communicates with atmosphere.Outer cover is provided with drain port.
The inner chamber of work bellows communicates with atmosphere by connecting tube, and the inner chamber of balance bellows communicates with atmosphere with space between ring flat-plate by left side adapter.Drain port is provided with manual plug screw or automatic switch mechanism.
About take over and respectively to have 3-5 windows, during work, a medium left side is taken over and is flowed into, and flows to the outer cover inner chamber through window, two bellowss all are subjected to external pressure, the contractile force of generation acts on outer cover simultaneously, and equal and opposite in direction, direction is opposite, is able to balance.The bellows outer wall contacts with medium, does not have chlorine from having in the bellows inner product in water, for accumulating liquid and then can in time discharge by drain port in the outer cover.
The utility model is the thermal distortion of absorption tube wire system effectively, and balancing axial thrust prevents the corrosion of chlorion water to corrugated stainless steel tubing, and can not produce the column unstability, thereby reliable performance, long service life, applied range.
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.
Consistent with balance bellows 4 sizes by the work bellows 5 that stainless steel is made, the end 13 that two bellowss are relative is all taken over 1 one-tenth sealed type welding with a left side with 14.Their the other end becomes sealing or welding with the two ends of outer cover 3 by ring flat-plate 2 or right adapter 8 respectively with ring flat-plate 7.The inner chamber of two bellowss communicates with atmosphere by connecting tube 6 and space 15 respectively.End socket 10 is dead with the end weldering of left and right adapter.The area sum that respectively has 9,4 windows of 4 windows in the left and right adapter equals the endoporus cross section of left and right adapter.Outer cover is provided with drain port 11 and manual plug screw 12.
