The invention discloses a one-way throttle valve based on effect of eliminating hydraulic fluctuations. The one-way throttle valve comprises a valve body and a one-way valve set arranged in a valve cavity of the valve body, wherein an oil port A, which is communicated with the valve cavity in a radial direction, is processed in a position, relatively close to the front end, of the valve body; the valve cavity is a through hole which penetrates through front and rear end surfaces of the valve body; an oil port B is formed in the front orifice of the valve cavity; the rear orifice of the valve cavity is an assembly opening with inner threads; the one-way valve set is mounted in the valve cavity in a one-way opening mode from the oil port B to the oil port A; a detachable damper, which is communicated with the oil port A and the oil port B, is arranged in the one-way valve set in a replaceable mode; and the one-way valve set comprises a pressure-regulating nut, a pressure-regulating spring and a one-way valve element, which are mounted in an assembly opening in a sealed mode. According to the one-way throttle valve, the detachable damper which can be replaced according to damping size needs is mounted in an axial oil path of the one-way valve element by adopting a spiral assembly mode, so that the whole one-way throttle valve is concise and compact in structure, and therefore, miniaturization of the one-way throttle valve can be realized, and the one-way throttle valve has the characteristics of a small size, and stable performance.
Description
technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a one-way throttle valve based on eliminating hydraulic fluctuations. Background technique [0002] One-way throttle valve is a valve that controls fluid flow by changing the throttle section or throttle length. In the prior art, due to the design structure of some of these valves, the volume of the valve body is relatively large. When this happens, the volume of the entire integrated valve will be relatively large, so the miniaturization of the one-way throttle valve is also the key to the miniaturization of the integrated valve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a one-way throttle valve based on the elimination of hydraulic fluctuations, which has simple structure, stable performance, small volume, and is suitable for the installation of highly integrated valve groups. [0004] The technical...
