Problems solved by technology
[0004] The present invention designs an emergency device and emergency method for a high-altitude, high-lift, high-pressure, long-distance water delivery pipeline. The technical problem it solves is that the water in the high-altitude, high-lift, high-pressure, long-distance water delivery pipeline is easy to freeze in a severe cold climate environment. As a result, high-pressure water pipelines cannot continue to operate in severe cold climates

Embodiment Construction
[0019] Combine below figure 1 , To further explain the present invention:
[0020] Unless otherwise noted, the descriptions of the following specific embodiments are all based on high-pressure water pump operation and the flow direction of fluid in the pipeline when the water is delivered to the end of the pipeline through a 10.7km pipeline as the "positive direction" for reference, the arrow direction in the figure.
[0021] Set up two high-pressure water pumps of the same model in parallel at the pumping station. When the two high-pressure water pumps are started at the same time, the fluid in the pipeline will get twice the flow rate of when a high-pressure water pump is started, so that the water in the pipeline is in severe cold weather. It is not easy to freeze in the environment, ensuring that the high-pressure water pipeline can continue to operate in the severe cold climate.
[0022] Emergency methods and devices:
[0023] (1) Install the first check valve 4 and the first ou...

The invention relates to an emergency device and emergency method for a high-altitude, high-lift, high-pressure, long-distance water delivery pipeline. A plug (7) is provided at one end of the outlet pipeline (15), and one end of the first high-pressure water pump (2) is connected to the first high-pressure The water pump inlet pipe (1), the first high-pressure water pump outlet pipe (5) is connected between the other end of the first high-pressure water pump (2) and the outlet pipe (15). The outlet pipe (5) of the high-pressure water pump is provided with a first pressure transmitter (3), a first check valve (4) and a first outlet valve (6) in sequence. The high-pressure water pump water delivery equipment of the water flow rate in the pipeline (15). The present invention enables the fluid in the outlet pipeline to obtain twice the flow rate when starting a high-pressure water pump, so that the water in the pipeline is not easy to freeze in the severe cold climate environment, and ensures that the high-pressure water delivery pipeline can continue to operate in the severe cold climate environment. run.
Description
Technical field [0001] The invention relates to the field of pipeline water delivery, in particular to a high-altitude, high-lift, high-pressure and long-distance water pipeline emergency device and emergency method. Background technique [0002] High-altitude, high-lift, high-pressure, and long-distance water pipelines can effectively solve the problems of industrial water and civilian water in high-altitude and water-poor areas. The operation and maintenance of the pipeline has withstood the test of the harsh geographical environment in high altitude areas. [0003] The high-altitude, high-lift and high-pressure water pipeline attached to this emergency method and device is located in Dongchuan District, Kunming City, Yunnan Province. The highest elevation in its territory is 4344.1 meters, the lowest elevation is 695 meters, and the elevation difference is 3649.1 meters. The deep fault zone, with high mountains and deep valleys, steep terrain, and strong geological erosion, has...
