结构特点与用途:
Strucure features and usages:
- 全关时手轮按顺时针方向旋转;
- 可以安装在管道的任何位置上,介质从下往上流;
- 不锈钢截止阀适用于各类腐蚀性介质的管道上,有良好的防腐性和足够的强度;
- 合金钢截止阀适用于耐高温的蒸汽、油品管道上,具有耐高温特点。
- When fully closed,the handwheel rotates clockwise.
- Able to be mounted on any position of the pipeline,the medium flows from down to up.
- Stainless steel made stop valve is of good anti-corrosive property and enough strength and suitable for various pipelines with corrosive medium.
- Alloy steel made stop valve features high-temperature resistance,suitable for high-temperature steam and oil goods pipelines.
