Description

Twin flue parallel connection long distance delivery pipeline

Technical field：

The utility model is related to pipe transportation technology field, more particularly to a kind of twin flue long distance delivery pipeline in parallel.

Background technology：

Pipeline is as the fluid mode of movement commonly used in national product, life, and it is using quite varied, with country's peace Entirely, people's lives are closely bound up.Especially oil transportation, gas transmission, the long range of water delivery, the pipeline of big throughput rate, even more require that it will do To round-the-clock uninterrupted even running completely.And one wire design is used in existing design pipeline, in actual production In, because piping failure leakage or other adapter line need, take stopping production to construct or press and open holes closure repairing, cause great economy Loss and environmental pollution, are particularly related to goods and materials conveying (such as pipeline of transferring natural gas from the west to the east, Sino-Russian petroleum pipeline of national strategy, the people's livelihood Road), convey in a high voltage state, once leaking, existing press and open holes blocking technology can not be realized under high-pressure situations On-line production emergency work construction, its influence caused, loss are difficult to imagine.

Utility model content：

The technical problems to be solved in the utility model is to provide a kind of twin flue long distance delivery pipeline in parallel, and the device is real Branch line can be repaired or be increased to on-line operation pipeline under the conditions of on-line production by having showed, easy to operate, operating efficiency is high, Engineering cost is low, improves the use stationarity and security of long distance pipeline, it is to avoid because connecting road or emergency management by pipeline The stopping transportation caused, reduces the risk that unnecessary plugging holes are brought, it is ensured that conduit running it is steady unobstructed.Overcome existing list Stopping transportation is needed when the leakage of line piping failure or other adapter line, the deficiency of heavy economic losses and environmental pollution is caused.

Technical solution adopted in the utility model is：A kind of twin flue long distance delivery pipeline in parallel, including two pipes Line；Two pipeline be arranged in parallel, the tee ball valve being connected with multiple tee ball valves, two pipelines is spaced on every pipeline mutual It is connected on correspondence, two pipelines between mutual corresponding two tee ball valves by connecting pipeline.

The beneficial effects of the utility model are：The utility model can enter under the conditions of on-line production to on-line operation pipeline Branch line is repaired or increased to row, and easy to operate, operating efficiency is high, engineering cost is low, improves the use stationarity and peace of long distance pipeline Quan Xing, it is to avoid the stopping transportation caused by road or emergency management are connected in pipeline side, reduces the wind that unnecessary plugging holes are brought Danger, it is ensured that conduit running it is steady unobstructed.

Brief description of the drawings：

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Fig. 1 is structural representation of the present utility model.

Embodiment：

As shown in figure 1, a kind of twin flue long distance delivery pipeline in parallel, including two pipelines 1；Two pipelines 1 are parallel to be set Put, interval is connected with tee ball valve 2 mutually correspondence, two pipelines on multiple tee ball valves 2, two pipelines 1 on every pipeline 1 It is connected on 1 between mutual corresponding two tee ball valves 2 by connecting pipeline.

Once somewhere piping failure needs construction, two tee ball valves 2 at the pipeline section two ends are switched into closed mode, Fluid is led naturally into another pipeline 1 and normally conveyed, carry out pipeline purging, construction to problem pipeline section, it is to be onstructed after the completion of, recovering should Pipeline section is run.

It is understood that specifically described above with respect to of the present utility model, be merely to illustrate the utility model and not The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with The utility model is modified or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality Within new protection domain.

Claims (1)

1. a kind of twin flue long distance delivery pipeline in parallel, including two pipelines (1)；It is characterized in that：Two pipeline (1) is parallel Set, the tee ball valve (2) that interval is connected with multiple tee ball valves (2), two pipelines (1) on every pipeline (1) is mutually right Should, it is connected on two pipelines (1) between mutual corresponding two tee ball valves (2) by connecting pipeline.
