| 阀门的特性一般有两种，使用特性和结构特性。 There are generally two kinds of valve characteristics, service characteristics and structural characteristics. 使用特性：它确定了阀门的主要使用性能和使用范围，属于阀门使用特性的有：阀门的类别（闭路阀门、调节阀门、安全阀门等）；产品类型（闸阀、截止阀、蝶阀、球阀等）；阀门主要零件（阀体、阀盖、阀杆、阀瓣、密封面）的材料；阀门传动方式等。 Use characteristics: it determines the main use performance and use scope of the valve, which include: Valve category (closed-circuit valve, regulating valve, safety valve, etc.); product type (gate valve, globe valve, butterfly valve, ball valve, etc.); material of main parts of the valve (valve body, bonnet, stem, disc, sealing surface); valve transmission mode, etc. 结构特性：它确定了阀门的安装、维修聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 、保养等方法的一些结构特性，属于结构特性的有：阀门的结构长度和总体高度、与管道的连接形式（法兰连接、螺纹连接、夹箍连接、外螺纹连接、焊接端连接等）；密封面的形式（镶圈、螺纹圈、堆焊、喷焊、阀体本体）；阀杆结构形式（旋转杆、升降杆）等。 Structural characteristics: it determines some structural characteristics of the installation, maintenance and other methods of the valve, including the structural length and overall height of the valve, the connection form with the pipeline (flange connection, thread connection, clamp connection, external thread connection, welding end connection, etc.); the form of the sealing surface (insert ring, thread ring, surfacing, spray welding, valve body) ; valve rod structure (rotary rod, lifting rod), et |
