Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model.
As shown in Figure 1, the utility model provides a kind of pipeline elbow leak repairing clamp, for blocking wearing in pipeline elbow
Hole, pipeline elbow leak repairing clamp include gasket 1, snap-gauge 2, support frame 3 and pressing plate 4, and gasket 1 is for being placed on pipeline elbow
Perforation on, gasket 1 can cover perforation, for block perforation, such as gasket 1 be rubber sheet gasket, utilize the bullet of gasket 1
Property block perforation；Snap-gauge 2 is placed on gasket 1, and the medial surface of snap-gauge 2 towards gasket 1 is arcwall face, is used for gasket 1
It is located in perforation；Support frame 3 is U-shaped structure, and support frame 3 can be set in outside pipeline elbow；Pressing plate 4 is connected to support frame 3
Between both ends, and it is placed in the side backwards to gasket 1 of snap-gauge 2, that is, is located at the side with perforation of pipeline elbow, i.e.,
Pressing plate 4 and support frame 3 surround pipeline elbow, and gasket 1 is pressed in pipeline elbow by pressing plate 4 by snap-gauge 2, so that gasket
1 blocks perforation.Since snap-gauge 2 has arcwall face, snap-gauge 2 can be such that the abutting of gasket 1 is located at and wear under the pressuring action of pressing plate 4
The arc outer wall face of pipeline elbow around hole, to block perforation.
The pipeline elbow leak repairing clamp of the utility model can quickly be set in outside pipeline elbow and block perforation, without adjusting
Sump oil leakage will not be occurred, environmental pollution is avoided, save sump oil handling without being closed a well in nitrogen vehicle and electrical welding tractor
With mitigation labor intensity of workers.
As shown in Figure 1 and Figure 2, in a specific embodiment, through-hole 41 there are two being opened up on pressing plate 4, the two of support frame 3
End is each passed through two through hole 41, and the both ends of support frame 3 are cylindrical and have external screw thread, and the both ends of support frame 3 are separately connected one
Clamping nut 5,5 clamping platen 4 of clamping nut, in the present embodiment, support frame 3 is alternatively referred to as U bolt.
The present embodiment is connected by screw bolts mode, increases contact area and extruding force between pressing plate 4 and snap-gauge 2, mentions
High closure pressure, it is convenient for disassembly and assembly, quick, quickly leak repairing clamp is mounted in pipeline elbow convenient for operator, mitigates work
People's labor intensity.
But the utility model is not limited to this, and can also be not provided with clamping nut 5, using other way fixation clip 4, example
Such as: the through-hole 41 of pressing plate 4 is interference fitted with support frame 3；Multiple screw holes, screw hole and through-hole 41 can also be opened up on pressing plate 4
Connection, and the central axis of the central axis of screw hole and through-hole 41, after the both ends of support frame 3 are each passed through two through hole 41, in spiral shell
Screw is screwed in hole, holds out against the lateral wall at 3 both ends of support frame.
Further, it is folded with gasket 6 respectively between two clamping nuts 5 and pressing plate 4.
As shown in Figure 1, support frame 3 is U-shaped bar, and support frame 3 is by 31 He of semicircular ring in another specific embodiment
Two straight-bars 32 being parallel to each other for being connected to 31 both ends of semicircular ring are constituted.
By setting rod-like structure for support frame 3, makes to contact between support frame 3 and pipeline elbow for line, overcome pipe
Line elbow surface different parts curved surface changes the defect for causing face contact not easy to manufacture greatly.
Further, the internal diameter of semicircular ring 31 is greater than the outer diameter of pipeline elbow, can smoothly cover outside pipeline elbow.
Again as shown in Figure 1, in a preferred embodiment, the medial surface of snap-gauge 2 can be with the pipeline around perforation
The outside wall surface of elbow is bonded, in other words the curvature of the medial surface (arcwall face) of snap-gauge 2 and the pipeline elbow around perforation
The curvature of outside wall surface (arcwall face) is identical, it may also be said to the outer wall of the medial surface of snap-gauge 2 and the pipeline elbow being located at around perforation
Face is adapted, to realize that snap-gauge 2 compresses gasket 1, and gasket 1 is made to be close to be located at the arc of the pipeline elbow of perforation surrounding
Outside wall surface.
Snap-gauge 2 therein can be obtained by interception, specifically, after corrosion failure occurs for pipeline elbow, according to elbow
Site of perforation corresponding position in the new pipeline elbow of same model intercepts one piece of plank, then by the plank pad in new pipeline elbow
Expansion radian is squeezed, fits closely the medial surface of the plank with pipeline elbow outside wall surface, the plank obtained in this way can be used as
Snap-gauge 2.
Certainly, snap-gauge 2 can also be by prefabricated acquisition, specifically, as shown in figure 3, the pipe that will be easy to happen corrosion failure
Line elbow 7 is divided into four regions, is followed successively by the area Nei Wan 71, the area Jin Neiwan 72, nearly excurvation area 73, excurvation area by inside to outside
74, this corresponding four regions make four pieces of snap-gauges respectively, enable the arc shaped inside face of four pieces of snap-gauges respectively with the area Nei Wan 71, close
The area Nei Wan 72, nearly excurvation area 73, excurvation area 74 arc outer wall face be adapted, fit, when wherein a certain region is corroded
When perforation, blocked using the snap-gauge in the corresponding region.
Further, snap-gauge 2 and pressing plate 4 are split type structure, that is, snap-gauge 2 and pressing plate 4 are two independent components.Specifically
It is that pressing plate 4 is plate, snap-gauge 2 is arc panel, and the side contacted on snap-gauge 2 with pressing plate 4 is arcwall face.Due to snap-gauge 2 and pressing plate
4 be split type structure, can effectively prevent the displacement of snap-gauge 2 or deflection caused by fastening because of two sides clamping nut 5 unevenly, to keep away
Exempt from sealed pressure reduction.
Further, the medial surface of gasket 1 towards perforation is arcwall face, the medial surface of gasket 1 can be located at perforation week
The outside wall surface for the pipeline elbow enclosed fits, so that gasket 1 can effectively block perforation.
It further, is face contact between gasket 1 and snap-gauge 2, so that snap-gauge 2 is to 1 stable position of gasket.
Further, the shapes and sizes of gasket 1 are identical as snap-gauge 2.
The above descriptions are merely exemplary embodiments of the present utility model, the model being not intended to limit the utility model
It encloses.Any those skilled in the art, made equivalent variations under the premise of not departing from the conceptions and principles of the utility model
With modification, the range of the utility model protection should belong to.And it should be noted that each component part of the utility model simultaneously
It is not limited only to above-mentioned overall applicability, each technical characteristic described in the specification of the utility model can select according to actual needs
One individually uses or selects the multinomial use that combines, and therefore, the utility model covers in the nature of things to be invented with this case
The related other combinations of point and concrete application.
