| 产品简介 |
|
|
| 伞齿轮截止阀结构特点和用处:
伞齿轮铸钢直通式截止（节流）阀严格按BS 1873、API6D、 GB/T12235 标准设计制造，截止阀的阀瓣沿着中心定位作升降运动，(衬套采用耐磨性能好，摩擦系数小的特殊材料制作)，动作灵活可靠，密封性能优良。产品广泛应用于石油、化工、制药、电力行业等各种工况的管路上。
伞齿轮铸钢直通式截止（节流）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)。
伞齿轮截止阀只适用于全开和全关，不允许作调节和节流。 伞齿轮截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不 泄漏。当介质由阀瓣下方进入阀门时，操作力所需克服的阻力，是阀杆和填料的摩擦力与由介质的压力所产生的推力，关“伞齿轮截止阀” 的力比开“伞齿轮截止阀 ”的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。
● 设计制造按GB12235-89
● 结构长度按 GB12221-89
● 法兰尺寸按JB/G79-94
