Abstract

本发明涉及一种带槽防滑加固型多合金平焊式法兰，它包括法兰本体（1），所述法兰本体（1）横截面呈圆环状，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凹槽（3），所述法兰本体（1）上设置有外孔（2），所述外孔（2）至少有二个，所述每个外孔（2）的内壁均设置有防滑层；所述法兰本体（1）上设置有至少一条加强筋（4）。本发明一种带槽防滑加固型多合金平焊式法兰，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

带槽防滑加固型多合金平焊式法兰
技术领域
本发明涉及一种法兰，具体是涉及一种带槽防滑加固型多合金平焊式法兰。
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槽防滑加固型多合金平焊式法兰。
本发明的目的是这样实现的：一种带槽防滑加固型多合金平焊式法兰，它包括法兰本体，所述法兰本体横截面呈圆环状，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凹槽，所述法兰本体上设置有外孔，所述外孔至少有二个，所述每个外孔的内壁均设置有防滑层；所述法兰本体上设置有至少一条加强筋。
与现有技术相比，本发明具有以下有益效果：
本发明一种带槽防滑加固型多合金平焊式法兰，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。
附图说明
图1为本发明一种带槽防滑加固型多合金平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
外孔2
凹槽3
加强筋4。
具体实施方式
参见图1和图2，本发明一种带槽防滑加固型多合金平焊式法兰，它包括法兰本体1，所述法兰本体1横截面呈圆环状，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凹槽3，所述法兰本体1上有外孔2，所述外孔2至少有二个，所述每个外孔2的内壁均设置有防滑层；所述法兰本体1上设置有至少一条加强筋4。
所述法兰本体1由不锈钢、碳钢或者镍钢制成。
