一、『产品描述』
进口高压法兰锻钢球阀所有部件均为锻件,采用下装式阀杆,设备倒密封结构,采用镶嵌式阀座,阀座背后设备O型圈,确保介质不外漏,密封面采用尼龙 1010,它的磨擦系数通常为巴氏合金的1/3,因此它是一种自然滑性材料。但抗弯曲强度和冲击强度及较高的延性,与金属不相上下。
Imported high pressure flange forging steel ball valveproducts all parts are forging, by downloading the stem,equipment fall airproof structure, adopts an embeddedvalve seat, seat O - ring behind equipment, to ensure thatthe media does not leak, sealing surface with nylon 1010,coefficient of friction, it usually Babbitt alloy 1/3, so it is anatural slide materials. But the ductility of flexural strength and impact strength and higher, and the metal be roughly the same.
二、进口法兰高压锻钢球阀工作原理:
进口法兰高压锻钢球阀是用带有圆形通道的球体作启闭件,球体随阀杆转动实现启闭动作的阀门,既正向旋转1/4圈(90°)时,阀关断。反向旋转1/4圈(90°)时,阀开启。。球阀的启闭件是一个有孔的球体,绕垂直于通道的轴线旋转,从而达到启闭通道的目的。球阀主要供开启和关闭管道和设备介质之用。
三、进口法兰高压锻钢球阀具有以下优点:
1、进口法兰高压锻钢球阀所有部件均为锻件
2、采用下装式阀杆,设备倒密封结构
3、采用镶嵌式阀座,阀座背后设备O型圈,确保介质不外漏
4、密封面采用尼龙或聚四氟乙烯,它的磨擦系数通常为巴氏合金的1/3,因此它是一种自然滑性材料。但抗弯曲强度和冲击强度及较高的延性,与金属不相上下。
