The utility model has the advantage of simple structure, compensation is not less than original corrugated pipes, and the utility model can accomplish repairing leak corrugated pipes without off production.
Description
The utility model relates to the packoff that leaks gas bellows.
The combustion gas FlexbleJoint is the displacement of expanding with heat and contract with cold that utilizes the corrugated tube extraction duct, and it mainly is welded by stainless steel ripple and carbon steel end Guan Jing.Existing gas bellows compensator has mainly proposed improvement to the structure of corrugated tube; the flexible compensator of a kind of gas piping is disclosed as Chinese patent 96231140.5; it has increased the structure of protective sleeve; protective sleeve is made up of big corrugated tube and loose collar; protective sleeve is enclosed within work ripple tube outside, and loose collar is sleeved in the adapter, and the protective sleeve flexibility is good; bendind rigidity is little, and compensation effect has raising.Another Chinese patent 90227236.5 discloses a kind of tefloncompensator, and it adopts teflon and the composite bed that accompanies glass fibre to replace general stainless steel ripple.In reality production reality, what occur in a large number is the leakage of corrugated tube, the leak position is often on the stainless steel ripple and the inside weld between the carbon steel end pipe of corrugated tube, the remedial measure of taking has two, and the one, stop production to overhaul is changed the corrugated tube of leakage, this method will cause the production line stopping production to bring about great losses, and most of corrugated tubes need be changed on the pipeline, the cost height, and workload is big; Another kind of way is that corrugated tube is repaired or encryption and package is put to leaking.
The purpose of this utility model is to provide a kind of gas bellows reparation non-metal compensator, and this compensator structure is simple, and compensation rate is not less than former corrugated tube compensation rate, and can not implement under the end-of-life state.
The utility model is achieved in that a kind of gas bellows reparation non-metal compensator, be coated on the virgin metal corrugated tube, on the pipeline, it is characterized in that described non-metal compensator comprises ring flat-plate, pressing plate, bolt, composite silicone rubber, packer ring, filler, ring flat-plate is made up of Circular Plate and annular pressing plate, annular pressing plate and Circular Plate are perpendicular and be welded on the Circular Plate, have equally distributed a plurality of bolt hole on the annular pressing plate, pressing plate is annular sheet and has equally distributed a plurality of bolt hole, match with the annular pressing plate of ring flat-plate, composite silicone rubber is a tubular, match with ring flat-plate and pressing plate in the tubular two ends, metallic bellows, pipeline, filler in filling in the space that two ring flat-plates and composite silicone rubber are formed, and bolt passes annular pressing plate, composite silicone rubber, packer ring and pressing plate are fastened into one.
With in the non-metal compensator, have two ducts in above-mentioned gas bellows reparation, have screw thread on the duct, and the sprue that cooperates is with it arranged at the Circular Plate upper and lower side of ring flat-plate.
With in the non-metal compensator, ring flat-plate is divided into two, on the Circular Plate of two semi-ring plates reinforcement plate is housed up and down, and is fastening by pull bar in above-mentioned gas bellows reparation.
Principle of work of the present utility model is to add a device in virgin metal FlexbleJoint outside, and is excessive from leakage point in order to prevent combustion gas.This device covers composite silicone rubber and filler on the corrugated tube leakage point, and the overlap joint mouth of silicon rubber is carried out the scene sulfuration, and it is become one, and with bolt and pressing plate silicon rubber is connected fasteningly with ring flat-plate, guarantees air tight.Because this device can be installed at the scene in factory process, can not finish the reparation of leaking corrugated tube under the end-of-life state.But the pre-allowance of composite silicone rubber layer and the vertical and horizontal displacement of flexibility extraction duct, compensation rate can be satisfied the expand with heat and contract with cold needs of displacement of extraction duct.On the Circular Plate of ring flat-plate, have the duct and can be used as the relief port and the freeing port of device, in order in the installation process to the displacement of combustion gas in the confined space and air with get rid of condensate water.
The utility model is simple in structure, and is easy for installation, and the compensation rate of the vertical and horizontal displacement of pipeline is not less than former corrugated tube, can not implement under the end-of-life state during reparation, can avoid stopping the supple of gas or steam changing the huge stopping production loss that is caused.
Fig. 1 is the utility model structural representation; Fig. 2 is the left view of Fig. 1; Fig. 3 is the local enlarged diagram of the utility model non-metal compensator; Fig. 4 is the relief port structural representation.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, the gas bellows reparation is leaked with the metallic bellows compensator that non-metal compensator is applied on the gas pipeline.It is to add a device in virgin metal corrugated tube outside.Non-metal compensator is made up of ring flat-plate 5, pressing plate 2, bolt 1, composite silicone rubber 3, filler 4, ring flat-plate 5 is made up of Circular Plate 7 and annular pressing plate 8, annular pressing plate 8 and Circular Plate 7 are perpendicular and be welded on the Circular Plate 7, have equally distributed a plurality of bolt hole on the annular pressing plate 8, ring flat-plate 5 by the people for being divided into two, so that on-the-spot the installation; On the Circular Plate 7 of two semi-ring plates 5 reinforcement plate 13 is housed up and down, fastening by pull bar 14 tensions; Pressing plate 2 is an annular sheet, has a plurality of equally distributed a plurality of bolts hole on the plate, matches with the annular pressing plate 8 of ring flat-plate 5, and for easy for installation, pressing plate 2 is divided into 4 by circumference, the back is installed strains fastening with bolt assembly 15; Composite silicone rubber 3 is a tubular, and the tubular two ends thicken, and matches with ring flat-plate 5 and pressing plate 2; Alumina silicate fibre cotton packing 4 in filling in the space that metallic bellows 9, pipeline 10, two ring flat-plates 5 and composite silicone rubber 3 are formed, and bolt 1 passes annular pressing plate 8, composite silicone rubber 3, packer ring 6 and the pressing plate 2 of ring flat-plate 5, and is fastened into one.
