Parameters
结构特点/Structural Features
该阀一面阀板采用独创的开孔设计,启动负荷小,阀腔无卡塞现象,另一面阀板采用陶瓷阀板单面密封,耐腐蚀性强,密封性好,使用寿命大。
当气源从上进气口通入时,气缸杆带动阀板向下运动,阀门关闭。当气源从下进气口通入时,气缸杆带动阀板向上运动,阀门开启。阀板与密封环之间加载弹簧,弹簧力始终使阀板压向密封环,又容许阀板在垂直上下方向移动,这有助于补偿阀门零件的热胀冷缩,并能克服任何背压变化对密封的影响与防止颗粒介质进入两密封面之间。在启闭过程中,阀板能产生自转,使得密封面之间产生研磨、抛光作用。而且由于阀体对通道偏心,在开启排卸物料时,会产生涡流,形成的物料旋涡会自行清扫阀门内腔。所有的这些特点,使得这种阀门具有超长的使用寿命,为您的系统安全运行提供了可靠的保证。
公称压力1.0Mpa适用温度:≤250°C 执行机构公称压力: 0.6-0.8Mpa也可根据用户要求定制。
