Embodiment

[0022] refer to Figure 1-6 , a relief valve mechanism with self-cleaning function, including a casing 1, an oil inlet 2 is opened through the bottom of the casing 1, the inner wall of the casing 1 is sealed and slidably connected with a valve core 3, and the end of the valve core 3 is opened through There is an oil passage hole 4, a release groove 13 is formed through the side wall of the oil passage hole 4, an oil return port 14 corresponding to the release groove 13 is formed through the side wall of the casing 1, and an outlet is formed through the side wall of the casing 1. The oil port 12, the inner top of the housing 1 is provided with a pressure regulating groove 5, the inner wall of the pressure regulating groove 5 is sealed and slidingly connected with the top plate 6, the bottom of the top plate 6 is fixed with a top rod 7, and the end of the top rod 7 is connected to the valve core 3. The upper end of the top plate 6 is connected with the pressure plate 9 through t...

Abstract

The overflow valve mechanism with the self-cleaning function comprises a shell, an oil inlet is formed in the bottom of the shell in a penetrating mode, a valve element is connected to the inner wall of the shell in a sealed and sliding mode, an oil passing hole is formed in the end of the valve element in a penetrating mode, and a release groove is formed in the side wall of the oil passing hole in a penetrating mode; an oil return opening corresponding to the release groove is formed in the side wall of the shell in a penetrating mode, an oil outlet is formed in the side wall of the shell in a penetrating mode, a pressure adjusting groove is formed in the inner top of the shell, a top plate is connected to the inner wall of the pressure adjusting groove in a sealed and sliding mode, and an ejector rod is fixed to the bottom of the top plate. The self-cleaning valve element has the advantages that the fan blades are impacted by oil liquid to rotate, then the scraping rod is driven to continuously rotate, the scraping rod can continuously clean the inner wall of the shell, impurities cannot stay on the inner wall of the shell, self-cleaning of the shell is achieved, the interior of the shell is kept clean, and normal use of the valve element is not affected; and manual regular cleaning is not needed, so that the use is more convenient.

Description

technical field [0001] The invention relates to the technical field of hydraulic parts manufacturing, in particular to a relief valve mechanism with self-cleaning function. Background technique [0002] The overflow valve is a kind of pressure control element in the hydraulic system. Its function is to overflow the excess pressure oil in the overflow system, so that the pressure of the system is always maintained within the setting range, and it plays a role in protecting the system and preventing the system Overload, also known as safety valve; [0003] When the contamination level in the oil is high, the contaminants may remain in the valve body, and the long-term accumulation will affect the normal movement of the valve core or cause the valve core to not move sufficiently, resulting in a reduction in the pressure control effect, resulting in equipment damage, and When the existing equipment is faced with an instantaneous high oil pressure shock, it is very easy to cause...
