Abstract
The utility model relates to a medium and large-size irregular flange high-temperature and high-pressure leakage blockage clamp, which mainly consists of two semi-annular clamp bodies through butt joint, wherein the two semi-annular clamp bodies are respectively provided with a plurality of injection passages and two semi-annular grooves and have the same structure, a pair of lug plates are respectively welded and connected onto the two semi-annular clamp bodies, grooves are respectively arranged on the two side surfaces of inner annular lug bosses of the semi-annular clamp bodies, a plurality of glue filling through holes are arranged between the two grooves at intervals, and each glue filling through hole is communicated with corresponding injection passages. The medium and large-size irregular flange high-temperature and high-pressure leakage blockage clamp has the advantage that the problem of low under-pressure leakage blockage success rate of the medium and large-size irregular flange is thoroughly solved.
Description
Technical field
The utility model relates to a kind of leak stopping anchor clamps, when large-scale irregular flange under particularly a kind of high temperature and high pressure condition takes place to leak, reach without the arrestment operation plugging effect in, large-scale irregular flange high temp high pressure leak stopping anchor clamps.
Background technique
In enterprises such as chemical industry that continuity is produced, oil refining, the leakage of flange often takes place, and seriously jeopardizes the continuous production run of device.In order to prevent continue to leak, and don't influence produces, and need under the situation of not stopping, block leakage point, and using the leak stopping anchor clamps in the existing technology is exactly a kind of way.Yet inevitable appearance dislocation, big or small flange, pad are selected problems such as improper for use in the process of flange design and installation; Because anchor clamps are measured and the existence of error; Cause that matching gap between flange and the anchor clamps is excessive can't to form a new sealed cavity, thereby can't reach the purpose that stops fluid to leak, cause the shutoff failure; System shutdown brings tremendous loss to producer.
Traditional flange clamp design is shown in figure one; Be that the bolton of pulling through ear and the extruding of the flexible filler in the half circle groove of filling station both sides form a new sealed cavity, realize plugging operations thereby through introduction valve and injection canal filling station is filled up sealer again.Yet the flange outer rim occurs irregularly shaped through regular meeting; On measuring and designing, also exist error; The fastening force that flexible filler and ear are pulled is not enough to form a new sealed cavity; Also reason causes sizing material excessive (race glue) because the control of the pressure process of injecting glue is bad etc. even formed new sealed cavity, causes the sealing failure.
201020668032.6 patent, announced " a kind of irregular flange pressure sealing anchor clamps ".This anchor clamps are to utilize sealer extruding soft packing to guarantee the applying degree of anchor clamps and flange.Design formula according to anchor clamps thickness:
In the formula: P: the squeeze pressure MPa of system pressure and sealing compound
Φ: weld joint efficiency
C: thickness additional amount
Δ: thermal expansion amount
In jig Design as shown in Figure 2; Because the squeeze pressure that has sealing compound of hole for injecting glue 6 is difficult to judge; In the process of jig design, there is very big problem; This because pressure excessive causes anchor clamps distortion at the injection sealing compound with compressing in the process of soft material with regard to being easy to, thereby makes sizing material excessive, and sealing is failed.
As depicted in figs. 1 and 2, run glue if will prevent sealer, the problem that at first will solve is how to form new sealed cavity, i.e. whether the applying of flange and anchor clamps is tight, secondly also will consider problems such as design of Clamping Apparatus condition.In the reality, because the problems such as overpressure of the dislocation of the error on measuring and processing, flange and abnormity, design of Clamping Apparatus thickness and injection sealing compound cause being difficult between flexible filler and the flange realize the tight of applying degree.Thereby cause sealing compound excessive, the sealing failure.
Summary of the invention
In view of the deficiency that existing technology exists, the utility model provides a kind of pressure that is applicable to that high temperature is high, in, the pressure sealing anchor clamps of large-scale irregular flange, in mainly solving, the large-sized flange outer rim is irregular and the problem of factor affecting plugging effect such as anchor clamps distortion.
The utility model is for realizing above-mentioned purpose; The technological scheme of being taked is: in a kind of, large-scale irregular flange high temp high pressure leak stopping anchor clamps; Mainly constitute by two semi-ring fixture butt joints that are respectively equipped with several injection canals and two half circle groove same structures; On two semi-ring fixturies, weld a pair of otic placode respectively; It is characterized in that: on the bi-side of the interior ring boss of said semi-ring fixture, be respectively equipped with groove, be provided with several injecting glue through holes two groove pitch, each injecting glue through hole communicates with pairing injection canal.
The advantage of the utility model: on original clamp structure basis, on the anchor clamps boss, open two grooves of coming round through injecting glue through hole and injection canal.During specific operation; Two groove the insides tumble in soft packing, along with the lifting of filling station sealing compound pressure, simultaneously constantly through injecting glue through hole extruding soft packing; The pressure of filling station sealing compound is high more; The dynamics of extruding soft packing is also just big more, so just can guarantee the existence because of filler all the time, and sizing material can't be broken through and form the excessive phenomenon of sizing material.Simultaneously filler is because the suffered extruding force of injecting glue through hole is vertical to the power that anchor clamps caused with sealing compound with system, also just need not consider when jig design thickness to cause because of the bad judgement of extruding force of sealing compound the problem of the bad design of anchor clamps thickness.Thereby in thoroughly having solved, the low problem of large-scale irregular flange pressure sealing success rate.

Embodiment
With reference to Fig. 5,6, shown in 7, a kind of in, large-scale irregular flange high temp high pressure leak stopping anchor clamps, mainly constitute by two semi-ring fixture 1 butt joints that are respectively equipped with several injection canals 1-1 and two half circle groove 1-2 same structures, the anchor clamps after the butt joint are ring bodies; On two semi-ring fixturies 1, weld a pair of otic placode 4 respectively; On the bi-side of the interior ring boss of semi-ring fixture 1, be respectively equipped with groove 3, be provided with several injecting glue through holes 2 two groove 3 pitch, each injecting glue through hole 2 communicates with pairing injection canal 1-1.
The utility model is through in the process of injecting glue; Give the flexible filler in the annular groove that forms after two half circle groove 1-2 butt joints in passing; Provide one along with injecting glue pressure increases and the extruding force of increase; Guaranteed to fit tightly between anchor clamps and the flange 5, in thoroughly having solved, the lower problem of pressure sealing success rate of large-scale irregular flange.
