Problems solved by technology
[0002] At present, in the field of hydraulic transmission technology, hydraulic valves as hydraulic control components or actuators are components with independent functions. The installation of independent hydraulic components is not only troublesome, especially because of the large space occupied It is not suitable for special places with limited space. At the same time, due to the long distance of hydraulic flow, the energy consumed by independent hydraulic components is relatively high. In addition, a single independent hydraulic valve also has the disadvantage of high cost. limit

Embodiment Construction
[0008] The valve core is cylindrical, with a deep large hole in the middle, and a small hole at the other end. The large hole and the small hole are on the same axis and communicate with each other. There is a thin spring, and a spherical valve is installed in the large hole of the valve core at the outer end of the thin spring. There is a tapered hole in the middle of the valve core seat, and the valve core seat is installed and fixed on the large opening of the valve core by threaded connection. One end in the middle of the valve body has a deep large hole, and the other end has a small hole, that is, an oil inlet, and the large hole communicates with the small hole. The valve seat at the inner end of the large hole is provided with the same overflow hole inside and outside. After the valve core is integrated with the above components, the valve core seat is turned inward, and the valve core seat is installed at the inner end of the large hole of the valve body. A thick spri...

Description
technical field [0001] The invention relates to an overflow valve, in particular to a one-way overflow valve, which belongs to the technical field of hydraulic components. Background technique [0002] At present, in the field of hydraulic transmission technology, hydraulic valves as hydraulic control components or actuators are components with independent functions. The installation of independent hydraulic components is not only troublesome, especially because of the large space occupied It is not suitable for special places with limited space. At the same time, due to the long distance of hydraulic flow, the energy consumed by independent hydraulic components is relatively high. In addition, a single independent hydraulic valve also has the disadvantage of high cost. limit. In addition, among all hydraulic components, one-way valves and relief valves are frequently used components, especially in hydraulic control systems, the functions of the one-way valve and the relief...
