The invention discloses a pressure regulating valve for a high-power diesel engine lubricating oil system, and relates to the technical field of machinery. In particular, the pressure regulating valvefor the high-power diesel engine lubricating oil system comprises a distribution block, a sliding valve piston is movably arranged in the distribution block, and a spring is movably connected to theoutside the sliding valve piston in a sleeving manner; and a flange cover is movably installed at one end of the distribution block, a bolt is movably installed in the flange cover, the bolt is in threaded connection with the distribution block, the exterior of the bolt is movably sleeved with a gasket, and a first oil outlet is formed in the front portion of the distribution block. The pressure regulating valve for the high-power diesel engine lubricating oil system is mechanical, simple in structure, high in reliability and convenient to operate, daily rapid inspection and regulation are met, the working efficiency is improved, the working intensity is relieved, and the lubricating oil pressure regulating requirements of lubricating oil systems of high-power diesel engines of different types can be met.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a pressure regulating valve used in a lubricating oil system of a high-power diesel engine. Background technique [0002] For large marine diesel engines, the lubricating oil pressure of the lubricating oil system affects its power performance, stability and reliability, and is also related to the safety of users. [0003] The lubricating oil system of a diesel engine should provide stable oil inlet pressure to ensure the lubrication and cooling effect of various moving parts and functional parts under different loads and speeds of the diesel engine. Too large or too small lubricating oil pressure will directly affect the normal operation of the parts and damage Important moving mating surfaces, so that the parts fail and the diesel engine cannot work. Due to changes in the external environment, the diesel engine itself needs to be equipped with a corresponding pressure regula...
