Abstract

本发明涉及一种带颈平焊式法兰，它包括法兰本体（1），所述法兰本体（1）横截面呈圆环状，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。本发明一种带颈平焊式法兰，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

带颈平焊式法兰
技术领域
本发明涉及一种法兰，具体是涉及一种带颈平焊式法兰。
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带颈平焊式法兰。
本发明的目的是这样实现的：一种带颈平焊式法兰，它包括法兰本体，所述法兰本体横截面呈圆环状，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。
与现有技术相比，本发明具有以下有益效果：
本发明一种带颈平焊式法兰，增强了两个设备或者管子之间的连接，使其更为牢固，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为本发明一种带颈平焊式法兰的结构示意图。
其中：
法兰本体1
凸起2
外孔3。
具体实施方式
参见图1，本发明一种带颈平焊式法兰，它包括法兰本体1，所述法兰本体1横截面呈圆环状，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由不锈钢、碳钢或者镍钢制成。
