Docking pipeline is with sealing anchor earTechnical field
The present invention relates to sealing fastener technical field, especially a kind of docking pipeline is with sealing anchor ear.
Background technology
In the gas extraction system of diesel engine, it is ensured that docking pipeline sealing, the sealing of existing docking anchor earRing material is owing to cannot meet its delivery temperature higher than 500 DEG C, and cannot use.The present invention provides onePlanting hooping structure, outer ring and sealing ring uses common iron can meet requirement.
Summary of the invention
The technical problem to be solved in the present invention is: cannot meet height to solve the sealing ring material of existing anchor earThe problem that temperature requires, it is provided that a kind of outer ring and sealing ring use common iron can meet the docking pipeline of requirementWith sealing anchor ear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of docking pipeline seals anchor ear,Including fastening outer ring and inner sealing ring, described inner sealing ring is arranged in fastening outer ring, and described inside is closeSeal ring disconnects and forms the end face one and end face two mutually coincideing, and on described end face one, the line of existence 2 does not fallsOn end face one, on described end face two, the line of existence 2 does not fall on end face two.Fastening outer ring is appliedFastening force, fastening outer ring is shunk, and makes inner sealing ring shrink, and by the pipeline clamping of docking, end face one is depositedNot falling on end face one at the lines of 2, the line that end face two exists 2 does not fall on end face two, endFace one and end face two are not planes, and end face one and end face two mutually extrude locked, thus are sealed by pipeline.AdoptUse common iron can meet requirement with this kind of hooping structure, fastening outer ring and inner sealing ring.
Concrete, described end face one and end face two are constituted by some continuous print intersecting planes.
Concrete, described end face one and end face two are curved surface, described end face one and the inner circle of inner sealing ringThe intersection of face and periphery is curve.
Concrete, state end face one and end face two is curved surface, described end face one and the front end face of inner sealing ringIt is curve with the intersection of rear end face.
Described fastening outer ring is the annulus with opening, opening annulus be respectively arranged at two ends with the first fastening plate andSecond fastening plate, described first fastening plate is from centre to the second fastening plate bending, and described first fastens the folding of plateHave between turn of bilge and the second fastening plate on gap, described first fastening plate and the second fastening plate and have correspondenceThrough hole, described first fastening plate and the second fastening plate are locked by bolt and nut.Regulation bolts and nuts, rightFastening outer ring applies fastening force, makes the first fastening plate and the second fastening plate close, the bending part of the first fastening plateContact with the second fastening plate, thus by the first fastening plate and the second fastening plate locking, make pipeline connect reliable,Good seal performance.
The invention has the beneficial effects as follows, the present invention relies on the cleaved facet of inner sealing ring mutually to extrude locking, willDocking pipeline seals, and uses this kind of hooping structure, fastening outer ring and inner sealing ring to use common ironMeet requirement.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification,The basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
Embodiment 1
As shown in figs. 1 and 3, a kind of docking pipeline is with sealing anchor ear, including fastening outer ring 1 and inner sealingRing 2, described inner sealing ring 2 is arranged in fastening outer ring 1, and described inner sealing ring 2 disconnects and being formed mutuallyThe end face 1 coincideing and end face 24, described end face 1 and end face 24 are by some continuous print intersecting planesConstitute.Fastening outer ring 1 applies fastening force, and fastening outer ring 1 is shunk, and makes inner sealing ring 2 shrink, willThe pipeline clamping of docking, the line that end face 1 exists 2 does not fall on end face 1, on end face 24The line having at 2 does not fall on end face 24, and end face 1 and end face 24 are not planes, end face 1Locked with end face 24 mutually extruding, thus pipeline is sealed.Use this kind of hooping structure, fasten outer ring 1Use common iron can meet requirement with inner sealing ring 2.
As in figure 2 it is shown, described fastening outer ring 1 is the annulus with opening, the two ends of opening annulus set respectivelyHaving the first fastening plate 5 and the second fastening plate 7, described first fastening plate 5 fastens plate 7 bending from centre to second,There is between bending part 6 and the second fastening plate 7 of described first fastening plate 5 gap, described first fastening plate 5Fasten the through hole having correspondence on plate 7 with second, described first fastening plate 5 and the second fastening plate 7 pass through spiral shellBolt nut check.Regulation bolts and nuts, apply fastening force to fastening outer ring 1, make the first fastening plate 5 HeSecond fastening plate 7 is close, and the bending part 6 of the first fastening plate 5 fastens plate 7 with second and contacts, thus by theOne fastening plate 5 is locked with the second fastening plate 7, makes pipeline connect reliable, good seal performance.
Embodiment 2
As shown in Figure 4, embodiment 2 is with the difference of embodiment 1: described end face 1 and end face 24Being curved surface, described end face 1 is curve with the inner headed face of inner sealing ring 2 and the intersection of periphery.
Embodiment 3
As it is shown in figure 5, embodiment 3 is with the difference of embodiment 1: described end face 1 and end face 24Being curved surface, described end face 1 is curve with the front end face of inner sealing ring 2 and the intersection of rear end face.
Embodiment 4
As shown in Figure 6, embodiment 4 is with the difference of embodiment 2: described end face 1 and end face 24Being curved surface, described end face 1 is curve with the front end face of inner sealing ring 2 and the intersection of rear end face.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, related workPersonnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to according to rightDetermine its technical scope.
