电动开关阀是一种转角为90°的旋转类阀门,密封性能优良,流量系数大,流阻系数小,结构简单,使用寿命长,便于维修。配用气缸式执行机构,电动球阀分开关式和调节式两种型号。产品广泛应用于化工、石油、轻纺、电力、食品制药、制冷、造纸行业的系统控制。法兰连接的管路能保持良好密封性能,便于维修更换,便于管路的封闭.
■流体阻力小、球阀是所有阀类中流体阻力*小的一种,即使是缩径球阀,其流体阻力也相当小。
■止推轴承减小阀杆摩擦力矩,可使阀杆长期操作平衡灵活。
■阀座密封性能好,采用聚四氟乙烯等材料制成的密封圈,结构易于密封,而且球阀的阀封能力随着介质压力的增设而增大。
■阀杆密封可靠,由于阀杆只作旋转运动而不做升降运动,阀杆的填料密封不易破坏,且密封能力随着介质的压力增设而增大。
■由于聚四氟乙烯等材料具有良好的自润滑性,与球体的摩擦损失小,帮球阀的使用寿命长。
■下装式阀杆和阀杆头部凸阶防止阀杆喷出,如火灾造成阀杆密封破坏,凸阶与阀体间还可形成金属接触,确保阀杆密封。电动开关阀 参数
