Problems solved by technology

Some diesel engines are limited by the working space, and the return water pipe of the preheater can only be installed on the cooling water pipe from the fresh water pump to the oil cooler. The cooling water pipe is cast aluminum, and there is only one threaded interface on it, which is used for installation and detection of fresh water pressure. If you want to connect the return water line of the preheater, you must remove the sensor line. At this time, it is impossible to detect the fresh water pressure when the diesel engine is running.

Abstract

The invention belongs to the structural design of diesel engines, and relates to a composite pipeline connector. The composite pipeline connector comprises a pipeline body (4), a connection body (1), a tee joint body (3) and sealing rings (2). A central through hole of the connection body is a preheating water return channel, the connection body is connected with a cooling water pipe of a fresh water pump and the pipeline body (4) through threads, and the pipeline body is connected with a stop valve in a preheater pipeline. Cooling water is led to a sensor pipeline through a small hole formed in the pipeline body (4), the tee joint body (3) is arranged on the connection body (1) and the pipeline body (4) in a sleeved mode, and the middle channel of the tee joint body (3) is connected with the sensor pipeline. The sealing rings (2) are arranged between the connection body (1) and the tee joint body (3) and between the pipeline body (4) and the tee joint body (3) respectively. The composite pipeline connector can meet the requirements for cooling water preheating and fresh water pressure detection of the diesel engine at the same time, the connection body (1) and the pipeline body (4) are connected through threads, and assembling and disassembling are convenient.

Description

technical field [0001] The invention belongs to the structural design of a diesel engine, and in particular relates to a composite pipeline connector. Background technique [0002] When the diesel engine is working in a severe cold area, in order to ensure the smooth start of the diesel engine, it is necessary to install a set of cooling water preheater to preheat the cooling water in the engine before starting the diesel engine. Some diesel engines are limited by the working space, the return water pipe of the preheater can only be installed on the cooling water pipe from the fresh water pump to the oil cooler. If you want to connect the return water line of the preheater, the sensor line must be removed, and the fresh water pressure when the diesel engine is running cannot be detected at this time. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a composite pipeline connector, which not only ensures the i...
