Abstract

本发明涉及一种三层承插焊式法兰,它包括法兰本体(1),所述法兰本体(1)横截面呈圆环状,由不锈钢层(1.1)、碳钢层(1.2)和加固层(1.3)组成,所述法兰本体(1)上靠近内径处设置有凸起(2),所述凸起(2)呈圆环状,所述法兰本体(1)上设置有外孔(3),所述外孔(3)至少有二个;所述法兰本体(1)上靠近内径处设置有凹槽(4)。本发明一种三层承插焊式法兰,使得两个设备或者管子之间的连接更为牢固,降低了设备或者管子的返修率,延长了其使用年限。

Description

三层承插焊式法兰
技术领域
本发明涉及一种法兰,具体是涉及一种三层承插焊式法兰。
背景技术
法兰,又叫法兰凸缘盘或突缘。法兰是管子与管子之间相互连接的零件,用于管端之间的连接;也有用在设备进出口上的法兰,用于两个设备之间的连接,如减速机法兰。传统的法兰由法兰本体和一圈孔眼组成,设备之间连接不够牢固,时间长后螺栓容易脱落。
发明内容
本发明的目的在于克服上述不足,提供一种连接牢固的三层承插焊式法兰。
本发明的目的是这样实现的:一种三层承插焊式法兰,它包括法兰本体,所述法兰本体横截面呈圆环状,由不锈钢层、碳钢层和加固层组成,所述法兰本体上靠近内径处设置有凸起,所述凸起呈圆环状,所述法兰本体上设置有外孔,所述外孔至少有二个;所述法兰本体上靠近内径处设置有凹槽。
与现有技术相比,本发明具有以下有益效果:
本发明一种三层承插焊式法兰,使得两个设备或者管子之间的连接更为牢固,降低了设备或者管子的返修率,延长了其使用年限。
附图说明
图1为本发明一种三层承插焊式法兰的结构示意图。
图2为图1中法兰本体的纵截面。
其中:
法兰本体1
不锈钢层1.1
碳钢层1.2
加固层1.3
凸起2
外孔3
凹槽4。
具体实施方式
参见图1和图2,本发明一种三层承插焊式法兰,它包括法兰本体1,所述法兰本体1横截面呈圆环状,由不锈钢层1.1、碳钢层1.2和加固层1.3组成,所述法兰本体1上靠近内径处设置有凸起2,所述凸起2呈圆环状,所述法兰本体1上有外孔3,所述外孔3至少有二个;所述法兰本体1上靠近内径处设置有凹槽4。
所述法兰本体1由不锈钢、碳钢或者镍钢制成。
