一种管路用两级密封法兰
摘要：
一种管路用两级密封法兰，属铁路车辆配件，主要适用于车辆制动管的连接及密封。它包括接头体和法兰体，接头体和法兰体通过密封圈密封。其关键技术是在接头体和法兰体之间设置E形密封圈和菱形密封圈对法兰实施两级密封。本实用新型法兰中的密封圈包括E形密封圈及菱形密封圈，两种密封圈在法兰中进行两级层叠式密封，密封可靠，在密封功能上互补，对法兰实施联合防护，两级防护可有效防止雨雪、风沙及腐蚀介质对法兰的损坏。
摘要（英）：

The utility model belongs to a railway vehicle fitting, and discloses a two-level sealing flange for pipelines. The two-level sealing flange for the pipelines is mainly suitable for connection and sealing of vehicle brake pipes and comprises a connector body and a flange body, and the connector body and the flange body are sealed through sealing rings. According to the key technology of the two-level sealing flange for the pipelines, an E-shaped sealing ring and a diamond sealing ring are arranged between the connector body and the flange body to achieve two-level sealing of a flange. The sealing rings in two-level sealing flange for the pipelines comprise the E-shaped sealing ring and the diamond sealing ring, the two sealing rings achieve the two-level stack-up type sealing, are reliable in the sealing, are complementary in sealing functions, and carry out joint protection on the flange. The two-level sealing can effectively prevent rain with snow, sand wind and corrosive medium from damaging the flange.
