Abstract

一种带密封环槽的管路用法兰,属铁路车辆配件,主要适用于车辆制动管的连接及密封。它包括法兰体、接头和密封圈。其关键技术是在接头上开有密封环槽,密封环槽为三面整体密封环槽,密封圈置于三面整体密封环槽内。本实用新型采用三面整体密封环槽接头的法兰,相比密封环槽是由接头与法兰体共同组成的法兰,三面整体密封环槽可为密封圈创造整体密封环境,为法兰提供有利的密封条件,使密封性能更加可靠。

Description

一种带密封环槽的管路用法兰
技术领域:
一种带密封环槽的管路用法兰,属铁路车辆配件,主要适用于车辆制动管的连接及密封。
背景技术:
长期以来,铁路车辆制动管的法兰密封性差,尤其是密封圈的密封环槽是由接头与法兰体共同组成,易导致制动管密封不良,压力空气漏泄,甚至失效,影响着铁路车辆的正常使用。
发明内容:
本实用新型要解决的问题就是针对以上不足而提供一种密封性能可靠的管路用法兰。其技术方案如下:
它包括法兰体、接头和密封圈。其关键技术在于接头上开有密封环槽,密封环槽为三面整体密封环槽,密封圈置于三面整体密封环槽内。
与现有技术相比本实用新型具有的有益效果是:
采用三面整体密封环槽接头的法兰,相比密封环槽是由接头与法兰体共同组成的法兰,三面整体密封环槽可为密封圈创造整体密封环境,为法兰提供有利的密封条件,使密封性能更加可靠。
附图说明:
图1,是本实用新型结构示意图;
图2,是图1俯视图;
图3,是法兰接头示意图;
图4,是图3俯视图。
具体实施方式:
如图1-图4所示,本实用新型包括法兰体2、接头1和密封圈3。其关键技术是在接头1上开有密封环槽1.1,密封环槽1.1为三面整体密封环槽,即密封环槽的底壁和两侧壁三面构成一个整体,密封圈3置于法兰接头的三面整体密封环槽1.1内。
