一、铸钢衬里直流截止阀概述:
手动、法兰连接、直流式、阀座密封面材料为衬胶、公称压力PN1.6mpa、阀体材料有不锈钢或铸钢、铸铁的截止阀。铸钢衬里直流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)。
“衬里直流截止阀”只适用于全开和全关,不 允许作调节和节流。 “衬里直流截止阀” 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“衬里直流截止阀” 的力比开“衬里直流截止阀 ”的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障。
