The invention relates to a pressure-adjustable valve assembly for a precision hydraulic system. The pressure-adjustable valve assembly comprises valve elements (1), sleeves (2) and sleeve flanges (3),the sleeve flanges are connected to one ends of the sleeves, and the valve elements are arranged in the sleeves. The valve elements comprise connecting end parts (11), cylinder parts (12), valve plates (13 and 14) and support columns (15), one ends of the connecting end parts are connected with the sleeve flanges, the other ends of the connecting end parts are connected with the cylinder parts, one ends of the supporting columns are connected with the cylinder parts, the other ends of the supporting columns abut against the inner walls of the sleeves, and through-flow gaps are always formed between the valve plates and the inner walls of the sleeves. The pressure-adjustable valve assembly is characterized in that the multiple valve plates (13 and 14) are arranged, the valve elements further comprise springs, one ends of the springs are connected with the valve plates, and the other ends of the springs are connected with the cylinder parts. The pressure-adjustable valve assembly can automatically adjust the opening degree of the valve plates, so that hydraulic flow in a pipeline keeps certain pressure constant, the structure is simple, and installation / disassembly are convenient.
Description
technical field [0001] The invention relates to the technical fields of fluid control and precision hydraulic system, in particular to a pressure-adjustable valve assembly used in a precision hydraulic system, which can be used to control the pressure and flow of hydraulic flow in a precision hydraulic system or a fluid pipeline system. Background technique [0002] The valve structure is widely used in various fluid control systems to control fluid pressure, flow or on-off, etc. However, the existing valve structure has the problems of complex structure, high cost, unstable / unstable pressure control, and inconvenient loading / unloading. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a pressure-adjustable valve assembly for precision hydraulic systems, which can automatically adjust the opening of the valve plate to make the hydraulic flow in the pipeline Keep a certain pressure constant...
