Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
Embodiment 1
The present embodiment pipeline compensator includes being set on telescopic pipes 4 and interconnective first sleeve and
Two sleeve pipes, the fixing connection of housing 8 that one end of described first sleeve is connected with described telescopic pipes 4, described
The other end of first sleeve is sheathed with one end of described second casing pipe sleeve to be tightly connected, described second sleeve pipe away from
One end of described first sleeve is fixing with described telescopic tube 4 to be connected；Described telescopic pipes 4 is flexible drives institute
Stating the second sleeve pipe to slide axially, described first sleeve is at least with the length of the sheathed part of described second sleeve pipe
The stroke of described telescopic pipes.
Wherein, the wherein said first sleeve of the present embodiment pipeline compensator is stainless steel tube 1, described second set
Pipe is seamless steel pipe 2, and the concrete fixed form of each parts is: described second sleeve pipe is away from described first sleeve one
The described telescopic pipes that end is corresponding is welded with the first flange 3, is sealed by weld seam；Seamless steel pipe 2 and the first method
Blue 3 welding, are sealed by weld seam；Stainless steel tube 1 one end is welded on fixing housing 8, passes through weld joint close
Envelope, the other end stretches in seamless steel pipe 2, and its sheathed inner length L is compensation dosage during pipeline extension.
Described first sleeve and the described second sheathed link position of sleeve pipe are provided with the second flange 6, the second flange 6 and institute
State the first flange 3 to fix by the way of bolt 7 attaching nut, and by the extruding of bolt 7 attaching nut
Power is connected fixing near one end of first sleeve to the second flange 6 and described second sleeve pipe；Described second flange 6
Medial surface on be disposed an outwardly facing the groove with inclination angle in described second sleeve pipe direction, described groove in arrange
The compound fluorine rubber seal element 5 having cross section to be trapezoidal double inclined plane shape, being combined of the most trapezoidal double inclined plane shape
5 one hypotenuses of fluorine rubber seal element are adaptive with the inclination angle of described groove；Described compound fluorine rubber seal element 5 with
The lateral wall of described first sleeve seals and arranges, thus the slipper seal realizing first sleeve and the second sleeve pipe sets
Put.
It is 45 ° as the bevel angle of groove described in a kind of alternative embodiment, being combined of trapezoidal double inclined plane shape
The bevel angle in fluorine rubber seal element 5 cross section is 45 °.
One of principal character of the present embodiment pipeline compensator is that the first flange 3 is mounting flange and telescoping tube
Road 4 welds, and is sealed by weld seam；Seamless steel pipe 2 welds with the first flange 3, is sealed by weld seam；No
Rust steel pipe 1 one end is welded on fixing housing 8, is sealed by weld seam, and the other end stretches in seamless steel pipe,
Its inner length L is compensation dosage during pipeline extension；Diameter of phi b of stainless steel tube 1 is more than telescopic steel pipe 4
Diameter of phi a, less than seamless steel pipe 2 diameter of phi c；Second flange 6 is slip flange, and Φ d is big for its opening diameter
In stainless steel tube 1 diameter of phi b, it can move freely at stainless steel tube 1；First flange 3 and the second flange 6
Connected by bolt 7 and nut.Wherein Φ e is the diameter of opening in shell.
The two of the principal character of the present embodiment pipeline compensator are the second flange 6 and compound fluorine rubber seal element 5
Design, the second flange 6 is containing carrying bevelled groove, and bevel angle is 45 °；Compound fluorine rubber seal element
5 cross sections are trapezoidal double inclined plane shape, and its bevel angle is 45 °.The purpose of inclined design is to realize power
The conversion in direction.
The three of the principal character of the present embodiment pipeline compensator are that fastening force is converted into the design of sealing force.Logical
The nut overregulating pipeline two panels flange provides fastening force, and the inclined-plane utilizing flange and trapezoidal fluorubber part will be tight
Gu power is decomposed into sealing force radially.In particular by clamp nut thus compress the first flange 3 and second
Flange 6, two inclined-planes of compound fluorine rubber seal element 5 are respectively by from seamless steel pipe 2 and the second flange 6
Extruding force, under the effect on inclined-plane, axial force is converted to radial force, thus by compound fluorine rubber seal element 5
Compress with stainless steel tube 1, it is achieved seal.
The four of the principal character of the present embodiment pipeline compensator are to pass through adjusting nut, in that context it may be convenient to realize
Mounting flange and slip flange disengage；In operating mode, badly or after the longer working time, compound fluorubber is close
Sealing likely ageing failure, now outwards winding nut, disengages two panels flange, the compound fluorubber more renewed
Sealing member.
The installation process of the present embodiment pipeline compensator is, as it is shown in figure 1, according to the workability of telescopic steel pipe
Matter, as pipeline predominantly extends, first sleeve takes large values, such as pipeline with the sheathed length " L " of the second sleeve pipe
Mainly compression, " L " the most then first sleeve gets the small value with the sheathed length of the second sleeve pipe.Judge according to operating mode
After specifying the length of compensation dosage " L " of stainless steel tube, installing each parts by Fig. 1, heat examination screws spiral shell after terminating
Bolt 7, by seamless steel pipe 2 and the extruding force of the first flange 6, realizes pipeline compensator under the effect on inclined-plane
And the sealing between telescopic steel pipe.When telescopic steel pipe 4 extends or compresses, pipeline compensator will be driven at rustless steel
Slide on pipe 1, thus play the effect of compensation of pipeline.
The major advantage that the present embodiment pipeline compensator is embodied is:
1) simple in construction.Seal by the combination of common pipe fitting flange, steel pipe, caulking gum is realized and
Compensate；
2) maintenance is convenient.By the operation to nut, caulking gum can be changed online, do not affect production；
3) nose balance amount is big.Extending into the stainless steel tube between two panels flange is compensation of pipeline amount, this length
Adjustable space is big.
Above, only presently preferred embodiments of the present invention, but protection scope of the present invention is not limited thereto, and appoints
How those familiar with the art is in the technical scope that the invention discloses, the change that can readily occur in
Or replace, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with
The protection domain that claim is defined is as the criterion.
