Description
Technical field
The utility model relates to the repairing apparatus of pipeline, particularly a kind of agent injecting type submarine pipeline leak stopping reinforcing device..
Background technique
The for example improvement and the maintenance of submarine oil, natural gas line generation leakage of submarine pipeline at present, no matter method commonly used both at home and abroad is to adopt open caisson and suction anchor technology, exactly the pipeline and the seawater that take place to leak are kept apart, adopt that again the leak-stopping technique of routine for example welds etc. to be repaired and reinforce.The operational method of the conventional leak-stopping technique of described utilization is a kind of numerous and jumbled, costly engineering of equipment of needs, often needs external technical assistance.
Summary of the invention
The technical problem that the utility model exists for the operational method of utilizing conventional leakage-baffling device reparation and reinforcing submarine pipeline in the solution prior art, and the agent injecting type submarine pipeline leak stopping reinforcing device. that a kind of equipment that cooperates with it is less, investment is lower is provided.
The utility model is for solving the above-mentioned technical problem that exists in the prior art by the following technical solutions: the folding housing that is supported in the rigidity of leak both sides pipeline by the end plate at two ends, the inboard of its two ends end plate is respectively equipped with inner end plate, be provided with the water-swellable rubber layer that engages with pipeline between end plate and the inner end plate, the outside of folding housing is provided with the air chamber and the gas/injecting injection valve and the expulsion valve of band charging air inlet, the outlet of air chamber is provided with the elastic membrane that is fixed in the folding inner walls, and the inboard of folding housing is provided with rubber seal curtain sheet and the securing means thereof that wraps leak.
Two-part up and down that described folding housing is hinged by a side, opposite side is provided with clamping bolt constitute, and two-part joint is provided with sealing gasket.
Two-part up and down of described formation folding housing, its each several part two ends are respectively equipped with fan-shaped end plate and the inner end plate that the bottom is a circular arc, be equipped with the fan-shaped water-swellable rubber layer that engages with pipeline between two plates, be provided with pressing plate respective shapes, that act on rubber layer between fan-shaped end plate and the fan-shaped water-swellable rubber layer, fan-shaped end plate is provided with and applies pressure to the adjustment screw of pressing plate.
Two-part up and down of described formation folding housing, its each several part two ends are respectively equipped with the air chamber of band charging air inlet.
Two-part up and down of described formation folding housing, wherein top is provided with gas/injecting injection valve, and the bottom is provided with expulsion valve.
The top of described formation folding housing is provided with viewing window and pressure gauge.
The described securing means that wraps the rubber seal curtain sheet of leak is a wiring.
The beneficial effects of the utility model and advantage are: after this leak stopping reinforcing device. is installed at the pipe leakage place under water, at first the water in the folding housing is discharged from expulsion valve by carrying the body of calming the anger by gas/injecting injection valve, the expansion of water-swellable rubber layer meanwhile makes this device become airtight die cavity.Subsequently again by gas/the injecting injection valve injects coagulable blocking agent to die cavity, and the gas in the die cavity is discharged from expulsion valve along with the progressively injection of blocking agent, and exhaust is finished and closed expulsion valve.In the process of injecting coagulable blocking agent, the air chamber of this device remains certain air pressure, this Pneumatic pipe cleaner is crossed elastic membrane and is filled the space of adjusting the blocking agent solidification shrinkage in the die cavity at any time and make it to enrich tight, and operation process can accurately be implemented each operating procedure by viewing window and pressure gauge.The folding housing of the rigidity of this device and solidify after blocking agent all have the effect of reinforcing pipes, also can be used for the connection of pipeline.Operation is reinforced in the enforcement leak stopping that can be used for underground, hazardous location and poisonous and harmful environment pipeline according to this device of this apparatus features equally.Can find out that by above analysis cooperating the utility model to fulfil assignment only needs small quantities of usual equipment, for example essential siren suit of air pump, blocking agent injection pump and operator and oxygen supply equipment etc. have the outstanding advantage that the equipment that needs usefulness is less, investment is lower compared to the prior art.
