J44H-160,J44H-320,J44Y-160,J44Y-320高压角式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)。J44H-320高压 角式截止阀只适用于全开和全关,不 允许作调节和节流。 J44H-320高压角式截止阀 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J44H-320高压 的力,比开J44H-320高压的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障。 产品名称: 产品型号:J44H/Y/W-320 设计制造按GB12235-89
