衬里直流截止阀概述: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。衬里直流截止阀性能规范:公称压力 Nominal pressurePN1.6MPa强度试验(Ps)Shell test密封耐压 Seal pressurePN1.6MPa阀体耐压 body pressurePN2.4MPa工作压力 working pressurePN1.6MPa使用温度working temperatureJ45F2-1.6-50°C-+120°CJ45F46-1.6-50°C-+120°C适用介质 Suitable medium强腐蚀性介质Strong corrosive medium衬里直流截止阀主要零件材料:名称 Name材料 Material阀体 BodyZG25II外壳内衬F46或衬F2或PFA阀盖 BonnetZG25IIF46或衬F2或PFA阀瓣 Disc优炭钢衬包F46或衬F2或PFA阀杆 Stem优炭钢填料 PackingF4U形圈填料压盖 Gland flangeZG25II阀杆螺母 Stem nutZHMn58-2-2定位螺母 Adjusting nutHT200垫片 GasketF4手轮 HandwheelHT200衬里直流截止阀主要外形尺寸和连接尺寸:公称通径DN(mm)主要外形尺寸和连接尺寸 Main outline dimensions and connection dimensionsLDD 1D 2bfdzD 0HH 1251601158565183144100220236321801351007818318412025127340200145110852031841402833065023016012510020318416031634465290180145120223184180353383803101951601352231882004374791003502151801502431882404795291254002452101802631882805426081504802802402102842383206056802006003352952653042312360650755
