法兰、法兰类零件

     法兰是一种盘状零件，在管道工程中最为常见，法兰都是成对使用的。 在管道工程中，法兰主要用于管道的连接。在需要  法兰盘连接两个管道的端头处，各安装一片法兰盘，低压管道可以使用丝接法兰，4公斤以上压力的使用焊接法兰。两片法兰盘之间加上密封垫，然后用螺栓紧固。 　　不同压力的法兰有不同的厚度和使用不同的螺栓。 　　水泵和阀门，在和管道连接时，这些器材设备的局部，也制成相对应的法兰形状，也称为法兰连接。 　　凡是在两个平面在周边使用螺栓连接同时封闭的连接零件，一般都称为“法兰”，如通风管道的连接，这一类零件可以称为“法兰类零件”。

The flange is a discoid parts, in pipeline engineering are the most common, flange are used in pairs. In the pipeline project, mainly used for pipeline flange connection. In need of flangeConnecting two pipe ends, each provided with a flange, pipe can use wire connecting flange, 4 kilograms of above pressure using welding flange. Two ring flanges coupled between sealing pad, and then the bolt fastening. Different pressure flange having different thickness and the use of different bolt. Pumps and valves, and pipeline connection, these equipment locally, also made the corresponding flange shape, also known as the flange connection. In two planes in the peripheral using bolt connection at the same time the closed connecting parts, generally referred to as" flange", such as ventilation pipeline connection, the parts can be called" flange type parts".
