Abstract

The invention provides a one-way valve and a hydraulic system. The one-way valve comprises a valve body and a plurality of valve balls; the valve body comprises an oil inlet end, an oil outlet end, a central channel and a plurality of peripheral channels, the peripheral channels comprise peripheral oil inlets formed in the oil inlet end and peripheral oil outlets formed in the oil outlet end, the central channel comprises a plurality of central oil inlets communicating with the peripheral channels in a one-to-one correspondence mode and a central oil outlet communicating with the oil outlet end, and the positions, communicating with the central oil inlets, of the peripheral channels are located between the peripheral oil inlets and the peripheral oil outlets. The valve balls are assembled in the peripheral channels in a one-to-one correspondence mode, the valve balls are jacked up and move towards the side close to the peripheral oil outlets when the oil pressure at the peripheral oil inlets is larger than or equal to a threshold value, so that the one-way valve is in an open state, the valve balls are reset under the action of gravity when the oil pressure at the peripheral oil inlets is smaller than the threshold value, the peripheral oil inlets are sealed, and the one-way valve is in a closed state. The conveying flow of the one-way valve can be increased, the large-flow requirement can be met, and the application scene is enlarged.

Description

technical field [0001] The present application relates to the technical field of wind power generation, in particular to a check valve and a hydraulic system. Background technique [0002] The hydraulic system includes a hydraulic transmission system and a hydraulic control system. The hydraulic system mainly refers to the hydraulic transmission system. The hydraulic transmission system includes a signal control part and a hydraulic power part, and the signal control part is used to drive the action of the valve assembly in the hydraulic power part. At present, due to the increase in the scale of petrochemical and chemical industry equipment, higher requirements are placed on the flow delivered by the hydraulic system. At present, the flow rate delivered by the conventional one-way valve is small, which cannot meet the demand for large flow rate, so its use is limited. Contents of the invention [0003] The present application provides a one-way valve and a hydraulic sy...
