Abstract
The present invention relates to a kind of Special fixture for pressure leakage blocking in chemical pipe, unitarily formed left clamp and right clamping body are connected into by fastener, have one to receive pipe hole in the unitarily formed axially one side, the receiving pipe hole constitutes first sealing surface with workpiece pipeline anchor ring, unitarily formed axial another side is engaged to form second sealing surface with the outline of vessel flange, an annular seal space is formed between two sealing surfaces, there are some hole for injecting glue in the cavity wall of annular seal space；There is radial convex loop, the internal diameter of the internal diameter less than the annular seal space cavity wall of radial convex loop in the cavity wall.Left clamp and right clamping body are first closed and put on vessel flange by the present invention, and the radial convex loop of fixture is embedded in two gaps of vessel flange, and left clamp and right clamping body then are connected into single piece through connection otic placode securing member is connected.Sealed solid glue is injected to annular seal space through hole for injecting glue with colloid-injecting gun again, enables to be contained in the vessel flange weld leak stopping in annular seal space.
Description
Technical field
The invention belongs to a kind of instrument used in chemical field, more particularly to a kind of special fixture of blocking up under pressure.
Background technology
Chemical engineering process is the continuous process carried out in complex conditions such as high temperature, high pressure, deep coolings, and raw material and product typically all have inflammable, explosive, poisonous and harmful property, therefore, leakage consequence once occurs in chemical industry feeding pipe will be hardly imaginable.In the prior art, the connection of two pipelines typically uses method as shown in Figure 1：After first pipe 1 aligns with the mouth of pipe of second pipe 2, with two vessel flanges 4,5 by equipment fastener 6, be linked together for both under the cooperation of seal, then welded admittedly in the outside of two vessel flanges 4,5 by mouth of pipe joint, forms a sealing pipeline for entirety.Problem is：The weld 3 of vessel flange 4,5 and pipeline usually occurs leakage phenomenon because of factors such as lack of penetration, slag inclusion, chemical medium corrosion.For this problem, the method for the treatment of was first to isolate this pipeline section in the past, then carried out repair welding or the pipeline section for more renewing.This method efficiency that not only wastes time and energy is low, and when running into Key pipe, it is necessary to first parking reprocessing, and this will have a strong impact on normal production, and enterprise is sustained a loss.
The content of the invention
To solve the above mentioned problem that prior art is present, the present invention is intended to provide a kind of Special fixture for pressure leakage blocking in chemical pipe, by the fixture, can be rapidly completed plugging operations, and need not make parking process.
To reach above-mentioned purpose, present invention employs following technical scheme：The structural feature of this Special fixture for pressure leakage blocking in chemical pipe is, including being connected into unitarily formed left clamp and right clamping body by fastener, have one to receive pipe hole in the unitarily formed axially one side, the receiving pipe hole constitutes first sealing surface with workpiece pipeline anchor ring, unitarily formed axial another side is engaged to form second sealing surface with the outline of vessel flange, an annular seal space is formed between two sealing surfaces, there are some hole for injecting glue in the cavity wall of annular seal space；There is radial convex loop, the internal diameter of the internal diameter less than the annular seal space cavity wall of radial convex loop in the cavity wall.
During specific implementation, connection otic placode is respectively equipped with the left clamp and right clamping body, left clamp and right clamping body are connected into single piece by securing member is connected through connection otic placode.
During specific implementation, there are four uniform hole for injecting glue in the cavity wall of the annular seal space.
Beneficial effect：The present invention is not disclosed to be reported and uses.The application can inject sealed solid glue under not parking situation by annular seal space, enable to be contained in the vessel flange weld in annular seal space and form new sealing, so as to solve leakage problem.
Brief description of the drawings
By embodiment, the invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is existing pipe connecting structure schematic diagram.
The main structure diagram of Fig. 2 one embodiment of the invention.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the top view of Fig. 1.
Fig. 5 is the broken section structural representation that this fixture is assembled on existing pipe connecting structure.
Sequence number is represented respectively in figure：First pipe 1, second pipe 2, weld 3, vessel flange 4, vessel flange 5, equipment fastener 6, left clamp 10, securing member is connected 101, connection otic placode 102, right clamping body 103, hole for injecting glue 104, workpiece receiving opening 105, annular seal space 106, bulge loop 107, cavity wall 108.
Specific embodiment
Referring to Fig. 2, and Fig. 3, Fig. 4 are combined, this is the fixture of a vessel flange 5 (referring to Fig. 1) for right side and design, if for the left-side device flange 4 in Fig. 1, the design of fixture is directionality problem, and structure is constant).Left clamp 10 and all semicirculars in shape of right clamping body 103, the radially, axially periphery of joint are provided with connection otic placode 102, and some through holes are provided with connection otic placode 102, and securing member is connected 101 can couple in single piece left clamp 10 and right clamping body 103 through some through holes.Workpiece receiving opening 105 is that the pipeline section periphery of the second pipe 2 in Fig. 1 constitutes first sealing surface under the cooperation of seal, with workpiece.As can be seen from Figure 3, the left side of fixture is a through hole corresponding with the outer contour shape of vessel flange 5, and it forms second sealing surface using the right flank of vessel flange 5, and annular seal space 106 is formed between first sealing surface and second sealing surface.Vessel flange 5 and its weld 3 for easily leakage occur all are contained in the annular seal space 106.
Referring to Fig. 5.As can be known from Fig. 5, after fixture assembling, vessel flange 5 and its weld 3 for easily leakage occur all are contained in the annular seal space 106, also, whole fixture is positioned on the lateral wall of vessel flange 5 by the bulge loop 107 that cavity wall 108 is extended.When carrying out pressure sealing operation operation, through hole for injecting glue 104 (cavity wall 108 is provided with four uniform hole for injecting glue 104, to improve plugging effect), sealed solid glue is injected into annular seal space 106, new sealing is formed using fluid sealant, intercept leakage point.Due to the axially position effect for having bulge loop 107, after fluid sealant is got into annular seal space 106, fixture will not make axial movement because extruding force is acted on and be disengaged with vessel flange 5, therefore, the sealed solid more plugging effects of glue quantity of injection are better.
