Description
Technical field
The utility model belong to the technical field that flange is let out shutoff, specifically relate to a kind of flange covering leaks clamping.
Background technique
In the chemical production device, connect by numerous flanges on the fluid pipe-line.The flange leakage phenomenon happens occasionally, and common solution is a parking maintenance, the excision inner material, and the dismounting flange is changed pad or flange according to leakage situation, solves and leaks.This will greatly influence the device long-term operation; The loss of avoiding unplanned parking accident to be caused; Avoided the energy to lose in a large number; Reduced part material, material, product losses, eliminate inflammable and explosive medium leakage, prevented device fire and explosive accident, guaranteed safety in production, eliminated noise, reduced environmental pollution.Processing leakage in time under the not parking situation need installed like this.Flange gasket on the mesohigh pipeline meets leakage, is not easy to again cut off under the situation of Medium Replacement sealing gasket in the pipe at once, and existing pressure sealing way is; Directly fill in filler or make a circular stirrup with the filler banding of filling in drill rod with band steel; Carry out temporary transient leakage eliminating, when this structure was used at the mesohigh flange leakage, structural strength was poor; Danger is bigger, is prone to leak; A kind of whole jig is that two semi-circlees dock into a circumference, wraps in the flange outside, with enclosed cavity of the common formation of flange crack; And in cavity, fill with the sealer filler, seal leakage point, when the mesohigh flange leakage; Pressure medium is higher; The pressure of glue can't be sealed seal point, and injection zone can't push compacting, and warp repeatedly injecting glue still leaks.
Summary of the invention
In order to address the above problem, the utility model aims to provide a kind of flange covering leaks clamping that is specially adapted to the mesohigh flange leakage.
The flange covering leaks clamping of the utility model is to be made up of bolt and slips, and described slips is that the two ends with two relative semicircle arcuation clamps are connected with in the bolt hole of card ear, card ear through bolt fastening formation.
Further improvement as the utility model; There is protruding rib key the center line position that the connection two of the inner ring surface of described clamp is picked up the ears; Both sides at the rib key are provided with the gel seal groove with corresponding position by two flange plates of shutoff, and the sealing groove is communicated with the overfolw hole that penetrates clamp.
As the further improvement of the utility model, the crest line of on the anchor ring of the root that is distributed with recess, rib key on the bi-side of rib key, arranging has the hole for injecting glue that runs through to clamp in the rib key, and on the hole for injecting glue of clamp, the injecting glue cock is housed.
As the further improvement of the utility model, on inboard two the relative planes of card ear, the tongue-and-groove that agrees with is each other arranged.
The flange covering leaks clamping of the utility model, reasonable in design is applicable to the sealing of mesohigh flange leakage, the rib bond energy is deep in the flange gap, directly glue is injected; It is inner to prevent that glue from getting into chemical pipeline, influences production run; Rib key side is provided with crest line and recess, reduces pressure medium; Reached easy and simple to handle rapidly, shorten engineering time, reduced recondition expense.The beneficial effect that band means of press seals expense can reclaim from eliminate the energy revealed and material in a short time.

Fig. 2 is the structural representation of the flange covering leaks clamping clamp of the utility model;
Fig. 3 is that Figure 1A-A is to plan view.
Embodiment
Flange leakage be since under differential pressure action the leakage and the seepage of generation, the flange leak stopping solves the problem that glue under high pressure can't seal.T type jig solves the bigger scope of pressure reduction.T-shape head stretches in the Flange Plane, has profile of tooth and semicircular one by one honeycomb on the T-shape head side, increase the leaking medium flow resistance method, in fact be exactly to reduce pressure to medium.
The flange covering leaks clamping of the utility model is to be made up of bolt 1 and slips 2, and described slips 2 is that the two ends with two relative semicircle arcuation clamps 5 are connected with card ear 3, block that through bolt 1 handle fastens formation in the bolt hole 4 of ear 3.
There is protruding rib key 6 the center line position that the connection two of the inner ring surface of described clamp 5 is picked up the ears, is provided with gel seal groove 7 in the both sides of rib key 6 with corresponding position by two flange plates of shutoff, and sealing groove 7 is communicated with the overfolw hole that penetrates clamp 58.
Be distributed with the crest line 10 of arranging on the anchor ring of root of recess 9, rib key 6 on the bi-side of rib key 6, the hole for injecting glue 11 that runs through arranged to clamp 5 in the rib key 6, and on the hole for injecting glue 11 of clamp 5, injecting glue cock 12 is housed.
The card ear has the tongue-and-groove 13 that agrees with each other on 3 inboard two relative planes.
Several kinds of design proposals commonly used are following:
