衬氟闸阀 闸阀是一种最带见的启闭阀门,利用两侧面密封呈楔状的闸板来接通或截断管路中介质,楔式闸阀不允许微量开启在管路中作节流装置用,以免因高速流动的介质冲蚀而加快密封面的损坏。FEP(F46)、PCTFE(F3)衬氟闸阀适用在-50℃~150℃的各种浓度的王水、硫酸、盐酸、氢氟酸和各种有机酸、强酸、强氧化剂,FEP还适用于各种浓度的强碱有机溶剂以及其它腐蚀性气体、液体介质的管路上使用。 详细说明
一、衬氟闸阀的特点
1.阀体有扁体和圆体两种形状:GB阀门采用圆体,ANSI磅级阀门DN≤300Lb采用扁体,DN≥400Lb采用圆体,阀体、阀盖的内腔和闸板、阀杆外表面等直接与介质接触的部件,全部名衬FEP(F46)等氟塑料;
2.密封副为FPF(F46)/ FEP(F46)或其它材料组合,摩擦系数小,启闭力矩低;
3.填料采用PTFE(F4)标准填料,密封性能好,维修更换方便;
4.带有弹性的闸板,可补偿闸板密封面与阀座密封面之间楔角偏差,吻合度好,密封效果理想;
5.介质可从两侧任意方向通过闸阀,适用于介质方向可能改变的管路上作用启闭装置。
二、衬氟闸阀基本型号
Z41F3型、Z41F46型和Z40F3、Z40F46型。
三、衬氟闸阀设计规范
遵循GB 12234/API6000标准
四、驱动方式
手动、电动、下齿轮、伞齿轮传动。
