Description

Technical Field

[0001] This utility model relates to the field of engine design and manufacturing, and in particular to a tee connector for a dual-channel high-pressure oil pipe. Background Technology

[0002] High-pressure fuel lines in engines are used to transport high-pressure fuel. Marine diesel engines typically have a double-walled fuel line structure. In the event of an internal pipe rupture, fuel leaks into the space between the two walls and is guided through a channel in the double-walled space to a collection tank, preventing high-pressure fuel from spraying out and causing fires or other accidents. Typical high-pressure fuel line tee fittings only have a high-pressure channel and no low-pressure channel.

[0003] Conventional high-pressure fuel line tee fittings only have a high-pressure channel and cannot connect to the low-pressure channel of a double-walled high-pressure fuel line. If the internal tubing of the high-pressure fuel line cracks and fuel leaks between the double-walled layers, the leaked fuel has nowhere to go when it encounters a traditional tee fitting. Over time, this can still lead to high-pressure fuel spraying to the outside, potentially causing fires and other accidents.

[0004] The goal is to design a tee connector that can connect to both the high-pressure and low-pressure channels of three high-pressure oil pipes. This would prevent fuel leakage into the double-walled interlayer in the event of an internal pipe rupture, which could then cause a fire by spraying high-pressure fuel onto the outside. The tee connector should also have holes for easy installation and connection.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
