Description

Technical Field

[0001] The utility model relates to the field of logistics supply and guarantee of oil transportation, and particularly relates to a multi-functional pipeline system. Background Art

[0002] According to the actual situation of oil transportation, it is usually necessary to integrate a large number of process functions in a pumping station to effectively control oil transportation. However, the more functions there are, the more complex the process becomes. Especially, it is more difficult to realize the integration of multiple functions and multiple processes in a limited mobile space or a fixed space. The larger the space is, the more complex the process is. If a set of pipeline systems cannot be shared for multiple processes, the space occupied by the pipeline systems will be extremely bloated. Operators will switch among relatively independent pipeline processes, and the timeliness of operation and the mobility of the pumping station will be greatly affected. At this time, either the functions need to be reduced to ensure the mobility and operability of the carrier, or the size of the carrier needs to be increased to reduce the mobility and operability. It is difficult to achieve both.

[0003] Therefore, there is an urgent need for a set of pipeline systems that can realize the sharing of multiple functional processes. Summary of the Invention

[0004] The purpose of the utility model is to provide a multi-functional pipeline system in view of the corresponding deficiencies of the prior art. This multi-functional pipeline system can concentrate multiple operation processes together, reducing the space occupied by redundant pipelines.

[0005] The object of the utility model is achieved by the following solution: A multi-functional pipeline system includes an oil pump, and the oil pump is connected to a power system and a transmission system. The front end of the oil pump is respectively connected to the pipelines of a first coarse filter and a second coarse filter through a three-way joint. A seventh valve and a sixth valve are respectively arranged at the front and rear ends of the pipeline of the first coarse filter. A fifth valve and a fourth valve are respectively arranged at the front and rear ends of the pipeline of the second coarse filter. The pipelines of the first coarse filter and the second coarse filter are connected to an oil inlet pipeline through a three-way joint. Between the oil inlet of the oil inlet pipeline and the coarse filter pipeline, a fourteenth valve, a tenth valve, a pig receiver, and an eleventh valve are sequentially arranged. Two three-way joints are arranged between the eleventh valve and the coarse filter pipeline. The three-way joint at the rear end is connected to an external oil addition pipeline. A pressure reducing valve and a thirteenth valve are sequentially arranged at the rear end of the external oil addition port of the external oil addition pipeline. The three-way joint at the front end is connected to one end of a pig launcher. The other end of the pig launcher is connected to an oil outlet pipeline. The rear end of the oil pump is connected to a metering oil transmission pipeline and a non-metering oil transmission pipeline through a three-way joint. A third valve is arranged on the non-metering oil transmission pipeline. A flowmeter is arranged on the metering oil transmission pipeline. A first valve and a second valve are respectively arranged at both ends of the flowmeter. The metering oil transmission pipeline and the non-metering oil transmission pipeline are connected to the oil outlet pipeline through a three-way joint. A bypass oil transmission pipeline is connected between the fourteenth valve and the tenth valve on the oil inlet pipeline through a three-way joint. One end of the pig launcher connected to the oil inlet pipeline is respectively connected to the bypass oil transmission pipeline and an oil leakage simulation pipeline through a four-way joint. A ninth valve is arranged between the pig launcher and the oil outlet pipeline. A twelfth valve and a check valve are sequentially arranged on the bypass oil transmission pipeline. An eighth valve is arranged on the oil leakage simulation pipeline. The oil leakage simulation pipeline is connected to the metering oil transmission pipeline and the non-metering oil transmission pipeline through a three-way joint. The oil outlet pipeline is connected to the bypass oil transmission pipeline, the pig receiver, the oil leakage simulation pipeline, the non-metering oil transmission pipeline, and the metering oil transmission pipeline through a four-way joint.

[0007] The fifteenth valve is a manual gate valve.

[0008] The power system is a diesel engine.

[0009] The transmission system is an electromagnetic clutch speed increaser.

[0010] The advantages of the utility model are that various pipeline processes can all be carried out using existing pipelines, achieving the purpose of integrating multiple process functions in a set of pipeline system, minimizing the space occupied by redundant pipelines as much as possible, improving the space utilization rate. The small-sized pipeline system also has a relatively small size of its carrier, which is more conducive to the flexible transfer of pump stations, the establishment of pump stations in limited spaces, and the reduction of the labor intensity of maintenance personnel.
