Abstract

The invention discloses a device for adjusting the areas of orifices of lubricating oil pipelines, and belongs to the technical field of design of aero-engine lubricating oil systems. The device comprises an adjusting pipeline arranged between the lubricating oil pipelines, and an adjusting valve. A channel is formed in the adjusting valve, a sliding way is arranged on the side portion of the channel, an adjusting plate (12) is slidingly arranged in the sliding way (11), when the adjusting plate (12) slides in the sliding way, the adjusting plate can at least partially block a through hole, athreaded hole (13) penetrating out of the adjusting valve is formed in one end of the sliding way in the sliding direction of the adjusting plate (12), a magnetic threaded rod (15) is screwed into thethreaded hole, a magnetic cylinder (14) is arranged at the end, stretching into the threaded hole (13), of the magnetic threaded rod (15), and the adjusting plate (12) is magnetic, and is attracted on the magnetic cylinder (14). Fluid in the lubricating oil system pipelines can be subjected to throttle control without splitting the lubricating oil pipelines in the test process, , and the purposeof throttling lubricating oil flow ways or air flow ways is achieved.

Description

technical field [0001] The application belongs to the technical field of aero-engine lubricating oil system design, and in particular relates to a device for adjusting the area of ​​an orifice in a lubricating oil pipeline. Background technique [0002] During the test run or test of the engine or tester on the ground bench, the lubricating oil system must ensure stable oil supply, oil return and ventilation, and the lubricating oil consumption should meet the operating requirements. Therefore, according to the test run or test status, it is necessary to install throttling orifice plates in the pipelines (oil supply, oil return, and ventilation), and to constantly replace throttling orifice plates with different throttling areas to achieve smooth oil flow or air flow. The purpose of road throttling is to meet the requirements of the engine or tester. [0003] At present, during the test run or test process, when the throttle orifice is installed, the test run or test needs ...
