Z941H-16C DN450电动不锈钢闸阀是一种较常见的启闭阀,利用闸板(即启闭件,在闸板中启闭件称为闸板或闸门,闸座称为闸板座)来接通(全开)或截断(全关)管路中的介质。它不允许作为截流用,使用中应避免将闸板微量开启,因高速流动的介质的冲蚀会加速密封面的损坏。闸板在垂直于闸门座通道中心线的片面作为升降运动,象闸门一样截断管路中的介质,故称做闸阀。 电动闸阀结构特点 1、选材考究,符合国内外相关标准,材料的全面质量高。 2、符合国内外先进标准的要求,密封可靠、性能优良、造型美观。 3、密封副配对先进合理,闸板和阀座的密封面采用不同硬度的司太立(Stellite)钴基硬质合金堆焊而成,密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长。 4、阀杆经调质及表面氮化处理,有良好的抗腐蚀性、抗擦伤性和耐磨性。 5、采用楔式弹性闸板结构,中大口径设置推力轴承,磨擦力小,并配有撞击手动,启闭轻松自如。 6、可采用各种配管法兰标准及法兰密封面形式,满足各种工程需要及用户要求。 Z941H电动法兰闸阀设计、制造标准 1.设计制造按GB/T 12234-89 2.结构长度按GB/T 12221-89 3.法兰连接尺寸按:JB/T 79-94 4.阀门检查和试验按GB/T 13927-92 电动闸阀其它型号: Z941H-10C DN32.
