供应高温截止阀J41Y江苏截止阀厂家
截止阀的启闭件是塞形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。阀杆的运动形式,有升降杆式(阀杆升降,手轮不升降),也有升降旋转杆式(手轮与阀杆一起旋转升降,螺母设在阀体上)。截止阀只适用于全开和全关,不允许作调节和节流。
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.
