Abstract
The utility model provides a pressurized plugging clamp of an irregular flange, which comprises a clamp body provided with a sealant injection through hole; sealant injection holes and sealant accommodating slots which are communicated with each other are arranged corresponding the positions of filling chambers, and thus, pressurized sealing can be implemented on a chemical unit without stop. In concrete operations, along with the increase of the sealant injection pressure of the filling chambers, a sealant is injected and accommodated simultaneously and continuously through additionally arranged sealant injection holes in the rear of fillers, and an extrusion force of the clamp on the fillers is enhanced at any time so as to ensure that lateral shear forces borne by the fillers cannot be broken, and thereby, the problem of lower pressurized plugging success rate under the conditions that the flange is irregular and the alignment tolerance is relatively greater is thoroughly solved. By adopting the pressurized plugging clamp, the pressurized plugging success rate can be effectively increased when the flange is irregular or the alignment tolerance of the flange is greater, the stop fault of a continuous chemical production unit is avoided and the safety of plugging operation staff in operations is ensured.
Description
Technical field
The utility model relates to the chemical industry leakage stopping technology, is specifically related to a kind of irregular flange pressure sealing anchor clamps.
Background technique
In the large chemical complex that continuity is produced, the leakage of flange often takes place, and jeopardizes the continuous production run of device.Usually the mode that adopts is a clamping bolt, when fastening inefficacy, has only and adopts traditional fixture type pressure sealing to eliminate leak source, avoids the loss of stopping.But in actual use, paired flange outer rim causes flange outer rim pairing back irregular because of defectives such as casting, installation, measurement error, machining errors, and alignment tolerance is bigger.Can't form effectively between flange and the anchor clamps and fit tightly, cause the shutoff failure, system shutdown.Gently then several ten thousand, the loss of hundreds of thousands unit, heavy then up to a million, up to ten million economic losses, even the life safety that jeopardizes the leak stopping operator sometimes.Traditional flange clamp designs as shown in Figure 1,
Traditional flange clamp design is respectively to increase the defective that an annular flexible filler remedies the flange outer rim by the filling station both sides, is suitable for relatively rule of two flanges, the situation (in the 2mm) that alignment tolerance is less.And when flange outer rim degree of irregularity surpasses 2mm than big or alignment tolerance, anchor clamps and flange rigidity applying degree are relatively poor, and flexible filler does not have enough intensity to seal up sealer from filling station, causes anchor clamps circumferentially to run glue, even flexible filler is extruded the sealing failure.
Referring to Fig. 1, if will prevent that sealer from running out of, what at first need to solve is exactly the applying degree of anchor clamps and flange and the strength problem of flexible filler.In theory, if do not consider that flexible filler only bears the extruding force from anchor clamps from filling station sealer pressure, can guarantee the applying degree of anchor clamps and flange so fully by the distortion of flexible filler.But if will seal firmly effectively, also should be taken into account the pressure of filling station sealer, at this time flexible filler will be subjected to the active forces that cross shear and these two of anchor clamps extruding forces from sealer are mutually 90 degree.And conventional brace is changeless to the extruding force of filler, is that the anchor clamps processing dimension is determined.The sealer pressure of filling station is then different, along with injecting glue pressure raises and raises, (this pressure size is relevant with flange rigidity applying degree along with anchor clamps, and promptly closely related with the alignment tolerance size, alignment tolerance is big more when reaching certain pressure, then the inboard load area of flexible filler is big more, the suffered cross shear of filler is big more, and then this pressure is more little), anchor clamps can't overcome injecting glue pressure from the filling station sealer to the extruding force of filler, sealer is run out of, the sealing failure.
The model utility content
At the prior art above shortcomings, problem to be solved in the utility model is exactly that irregular or alignment tolerance surpasses under the situation of 2mm in the flange outer rim, how to prevent extruding of sealer, guarantees the success of pressure sealing.
The technical solution adopted in the utility model is as follows: irregular flange pressure sealing anchor clamps, comprise the chuck body that is provided with the injecting glue through hole, and it is characterized in that, be provided with the gum-injecting port and the glue groove of connection at the position of corresponding filling station.
The utlity model has following advantage: on original clamp structure,, can realize not lay-by means of press seals of chemical plant installations by a newly-increased gum-injecting port and glue groove at two flexible filler rear portions.During specific operation, raising along with filling station sealer injecting glue pressure, simultaneously constantly by newly-increased filler rear portion gum-injecting port injecting glue, appearance glue, at any time strengthen the extruding force of anchor clamps to filler, all the time guarantee that the cross shear that filler is born can't make breakthroughs, thoroughly solved the lower problem of pressure sealing success rate under the irregular and relatively large situation of alignment tolerance of flange.
Can effectively improve when irregular flange or flange alignment tolerance are big, the probalility of success of flange pressure sealing has been avoided the trouble of shutdown of continuity chemical production device, has guaranteed the Security when the leak stopping operator operate.
Description of drawings
Fig. 1 adopts the structural representation of conventional brace to irregular flange pressure sealing;
Fig. 2 adopts the structural representation of the utility model to irregular flange pressure sealing.
Among the figure: 1 is chuck body, and 2 is the injecting glue through hole, and 3 is gum-injecting port, and 4 is glue groove, and 5 is flange, and 6 is filler, and 7 is glue injecting head.
Embodiment
As shown in Figure 2, irregular flange pressure sealing anchor clamps comprise the chuck body 1 that is provided with injecting glue through hole 2, are provided with the gum-injecting port 3 and the glue groove 4 of connection at the position of corresponding filling station.The utility model comes the extruding force of lifting clamp to filler by an additional forces that can increase at any time is provided above flexible filler, solved sealing problem.During specific operation, raising along with filling station sealer injecting glue pressure, simultaneously constantly by newly-increased filler rear portion gum-injecting port injecting glue, appearance glue, at any time strengthen the extruding force of anchor clamps to filler, all the time guarantee that the cross shear that filler is born can't make breakthroughs, thoroughly solved the lower problem of pressure sealing success rate under the irregular and relatively large situation of alignment tolerance of flange.See Fig. 2.The utility model has effectively improved when irregular flange or flange alignment tolerance are big, and the probalility of success of flange pressure sealing has been avoided the trouble of shutdown of continuity chemical production device, has guaranteed the Security when the leak stopping operator operate.
