Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to a replacement structure for a bypass pipeline. Background Art

[0002] When transporting liquids like water and oil, changes in pipeline routing often require the installation of multiple branch lines to modify the delivery route. Traditionally, these modifications involve drilling holes in the main pipeline and installing two-way or three-way fittings. Various devices are also installed along the pipeline. Some are simply for testing and do not hinder the flow of the medium within the pipeline. However, some are directly connected to the pipeline, potentially impacting its operation. Failure of these directly connected devices could affect the normal operation of the pipeline.

[0003] Currently, in a bypass line configuration, such as Figure 4 As shown, the ball valve 30 is closed, and the ball valve 10 and the ball valve 20 are opened. In this way, water passes through the ball valve 20 to the solenoid valve 2 and then to the ball valve 10, and enters the tank through the flow meter 300. When the solenoid valve 2 fails, it can only be closed by the ball valve 10 and the ball valve 20, and the solenoid valve 2 is disassembled for maintenance. At this time, the ball valve 30 is opened, and the incoming water passes through the ball valve 30 and then enters the tank through the flow meter 300, ensuring that the tank can normally enter water. This configuration uses more ball valves, which wastes production costs. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that a large number of ball valves are set in the liquid delivery pipeline in the prior art, resulting in unreasonable pipeline configuration and waste of production costs.

[0005] In order to solve the above technical problems, the utility model provides a replacement structure of a bypass pipeline, including: a first liquid tank, which is used to store liquid; a second liquid tank, which is arranged on the outer wall of the first liquid tank, and the second liquid tank is connected to the first liquid tank; a first flexible joint, which is connected to the pipeline for conveying liquid to the second liquid tank; a solenoid valve, which is arranged on the pipeline for conveying liquid to the second liquid tank; a ball valve, which is arranged on the pipeline for conveying liquid to the second liquid tank, and the ball valve is connected to the liquid inlet pipe, and the solenoid valve is located between the first flexible joint and the ball valve; a spare pipe, when the solenoid valve is damaged, the spare pipe is connected between the first flexible joint and the ball valve to replace the solenoid valve.

[0006] In one embodiment of the present invention, a first pipe is connected to the second liquid tank, one end of the first pipe extends into the second liquid tank, and the other end of the first pipe is connected to the first flexible joint.

[0007] In one embodiment of the present invention, a flow meter is connected to the first pipeline, and the flow meter is used to measure the liquid flow in the first pipeline.

[0008] In one embodiment of the present invention, a second pipe and a third pipe are provided between the first flexible joint and the ball valve, and the solenoid valve is connected between the second pipe and the third pipe.

[0009] In one embodiment of the present invention, two ends of the second pipeline are respectively connected to the first flexible joint and the solenoid valve.

[0010] In one embodiment of the present invention, two ends of the third pipeline are connected to the solenoid valve and the ball valve respectively.

[0011] In one embodiment of the present invention, the other end of the ball valve away from the third pipeline is connected to a liquid inlet pipe.

[0012] In one embodiment of the present invention, two ends of the spare pipe are respectively connected to a second joint and a third joint.

[0013] In one embodiment of the present invention, the first pipe is a U-shaped pipe.

[0014] In one embodiment of the present invention, the first pipe, the second pipe and the third pipe are all PP pipes.

[0015] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

[0016] The replacement structure of the bypass pipeline described in the utility model can remove the solenoid valve and the pipe connected to it when the solenoid valve fails, and then repair the solenoid valve. Then, a spare pipe is installed, the ball valve is opened, and water flows through the ball valve to the first joint and then flows into the tank through the flow meter to ensure that water can flow into the tank normally. This configuration can save the number of ball valves and save production costs. When there are multiple such configurations in a pipeline, the production cost can be greatly reduced.
