液压传动连接 快换接头 第2部分：20 MPa～31.5 MPa平面型
Application Summary AI generated
This standard specifies the dimensions, performance requirements, and test methods for flush-face quick-action couplings used in hydraulic fluid power systems operating at pressures between 20 MPa and 31.5 MPa. It is applied in industrial machinery, mobile equipment, and hydraulic tooling where leak-free connection and disconnection under high pressure are critical, such as in construction, agriculture, and manufacturing. The flush-face design minimizes fluid spillage and air inclusion, making it suitable for applications requiring cleanliness and environmental protection.
