Background technique
In the oil recovery process of crude oil, oil, need to use various oil transport pipelines, and oil transport pipeline will get rusty or occur certain breakage after the use long period, thereby oil accident occurs.In Oil products or Crude Oil Transportation process, occur that oily leakage may will cause serious harm, this just need to be rapidly to pipeline rush to repair, leak stopping processing.Current way is the valve of closing down on pipeline road, after then the oil in oil transport pipeline being extracted out, then studies for a second time courses one has flunked by the mode of welding there is damaged place; Although the method can be studied for a second time courses one has flunked oil transport pipeline, the time of the required consumption of the method is longer, and for the oil transport pipeline in petroleum recovering, some rush to repair situation promptly, fast, and this studies for a second time courses one has flunked mode and can not reach the requirement of operation.So, just need the short and leakage-baffling device fast of a kind of plugging time, be positioned near oil transport pipeline, can rush to repair in time oil transport pipeline, the impact that allows oil transport pipeline be subject in the time of work peak is less.
Model utility content
The purpose of this utility model is a kind of breakage spot of blocking quickly and efficiently oil transport pipeline of design, recover the leakage-baffling device of the oil transport pipeline repairing of oil transportation prestissimo.
The purpose of this utility model is achieved through the following technical solutions:
A kind of leakage-baffling device for oil transport pipeline repairing, the lock ring sheet II 2 that comprises the lock ring sheet I 1 of semicircular in shape and match with lock ring sheet I 1, described lock ring sheet I 1 and lock ring circle of the common formation of lock ring sheet II 2, this lock ring circle is used for clamping oil transport pipeline and carries out leak stopping processing.Lock ring sheet I 1 is all connected and fixed by clamping bolt 5 with the end, two ends of lock ring sheet II 2.Coordinate elastic sealing layer I 3 is installed in described lock ring sheet I 1 inner side, coordinate elastic sealing layer II 4 is installed in described lock ring sheet II 2 inner sides, the end, two ends of elastic sealing layer I 3, elastic sealing layer II 4 is all connected and fixed by described clamping bolt 5.Elastic sealing layer I 3 and elastic sealing layer II 4 combine and form one and stay close hoop circle clamping contact circle that match, round-shaped.
In order to realize better the utility model, described elastic sealing layer I 3 is gear shape or wavy near the cross section of the side of lock ring sheet I 1 inner side surface, and elastic sealing layer I 3 is semi-circular shape away from the cross section of the side of lock ring sheet I 1 inner side surface; The structure of the structure and elasticity sealing layer I 3 of described elastic sealing layer II 4 is identical.
Described elastic sealing layer I 3 and elastic sealing layer II 4 form by elastic rubber material manufacture.
The utility model is compared compared with prior art, has the following advantages and beneficial effect:
The utility model uses together with being connected by fastening screw select with two elastic sealing layers by two lock ring sheets, the clamping contact circle forming by two elastic sealing layers and the tight Interference contact of breakage spot of oil transport pipeline, make up the breakage spot of oil transport pipeline by elastic sealing layer, and can not occur because of the internal oil pressure of oil transport pipeline little oil accident.The utility model can be blocked the breakage spot of oil transport pipeline quickly and efficiently, and oil leakage accident can be controlled in time, is conducive to the normal conveying of fast quick-recovery oil.

Embodiment
Embodiment. as shown in Figure 1, a kind of leakage-baffling device for oil transport pipeline repairing, the lock ring sheet II 2 that comprises the lock ring sheet I 1 of semicircular in shape and match with lock ring sheet I 1, described lock ring sheet I 1 and lock ring circle of the common formation of lock ring sheet II 2, this lock ring circle is used for clamping oil transport pipeline and carries out leak stopping processing.Lock ring sheet I 1 is all connected and fixed by clamping bolt 5 with the end, two ends of lock ring sheet II 2.Coordinate elastic sealing layer I 3 is installed in described lock ring sheet I 1 inner side, coordinate elastic sealing layer II 4 is installed in described lock ring sheet II 2 inner sides, the end, two ends of elastic sealing layer I 3, elastic sealing layer II 4 is all connected and fixed by described clamping bolt 5.Elastic sealing layer I 3 and elastic sealing layer II 4 combine and form one and stay close hoop circle clamping contact circle that match, round-shaped.
The end, two ends of lock ring sheet I 1 all has round tube hole, and the shape of lock ring sheet II 2 is identical with shape, the structure of lock ring sheet I 1; When after lock ring sheet I 1 and lock ring sheet II 2 upper and lower being symmetrical arranged, lock ring sheet I 1 is just in time interconnected with the round tube hole of lock ring sheet II 2, and then fastening screw select 5 just links together lock ring sheet I 1 and lock ring sheet II 2 through the round tube hole of this connection.
Coordinate elastic sealing layer I 3 is installed in lock ring sheet I 1 inner side, coordinate elastic sealing layer II 4 is installed in lock ring sheet II 2 inner sides.The end, two ends of elastic sealing layer I 3 is equipped with round tube hole, elastic sealing layer II 4 is identical with shape, the structure of elastic sealing layer I 3, and lock ring sheet I 1, elastic sealing layer I 3, elastic sealing layer II 4 and the lock ring sheet II 2 of the present embodiment link together by fastening screw select 5.Leakage-baffling device inside after assembling is round-shaped clamping contact circle, the breakage spot close contact of this clamping contact circle and oil transport pipeline, thus realize the object of leak stopping.
Elastic sealing layer I 3 is gear shape or wavy near the cross section of the side of lock ring sheet I 1 inner side surface, and the gear shape of side and the wavy lock ring sheet I 1 that will more be conducive to closely clamp elastic sealing layer I 3, strengthen its sealing and plugging effect; Elastic sealing layer I 3 is semi-circular shape away from the cross section of the side I 31 of lock ring sheet I 1 inner side surface.The structure of the structure and elasticity sealing layer I 3 of elastic sealing layer II 4 is identical.
Wherein the inside radius of lock ring sheet I 1 and lock ring sheet II 2 is 150mm; The thickness of elastic sealing layer I 3 and elastic sealing layer II 4 is 30mm;
Elastic sealing layer I 3 and elastic sealing layer II 4 form by elastic rubber material manufacture.
When use, first by elastic sealing layer I 3 and damaged leakage of oil place of the corresponding encirclement oil transport pipeline of elastic sealing layer II 4, then in outside cooperation of elastic sealing layer I 3, lock ring sheet I 1 is installed, in outside cooperation of elastic sealing layer II 4, lock ring sheet II 2 is installed, by fastening screw select 5, lock ring sheet I 1, elastic sealing layer I 3, elastic sealing layer II 4 and lock ring sheet II 2 four parts is closely linked together.Elastic sealing layer I 3 and elastic sealing layer II 4 in be formed centrally clamping contact circle, in the process that screws along with fastening screw select 5, the circle of this clamping contact circle will be dwindled, thereby make elastic sealing layer I 3 contact more closely with elastic sealing layer II 4 with the outer tube wall of oil transport pipeline, because elastic sealing layer I 3, elastic sealing layer II 4 are made up of elastic rubber material, there is good sealability, the breakage spot of oil transport pipeline will be by elastic sealing layer I 3 or/and elastic sealing layer II 4 be blocked like this, and the leakage of oil of oil transport pipeline will be blocked fast.In elastic sealing layer I 3, having cross section is gear shape or wavy side, dwindles in process like this at clamping contact circle, and lock ring sheet I 1 will contact with elastic sealing layer I 3 tightr, and overall sealing, leak stopping performance are strengthened greatly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
