Q644气动三通球阀在结构上采用一体化结构,四面阀座的密封型式,法兰联接少,可靠性高,设计实现了轻量化。也能实现管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭。气动阀门结构紧凑、启闭迅速、流道畅通、流体阻力小。气动球阀密封性能好:利用四面阀座材料聚四氟乙烯弹性变形实现无泄漏密封。一阀多用:任一通口可用作入口而无泄漏,三通既可制成L型通口,也可制成T型通口。维修方便:在系统卸压后,无需拆下整个阀体就可进行检查和维修。阀门广泛适用于供水、石化、冶金、矿山、轻纺、能源、造纸、食品、钢铁等管路系统中对介质流向进行切换以及对介质的分流或混合流体。
气动三通球阀分L型和T型。L型三通球阀适用于介质流向的切换,能使相互垂直的两个通道连通:T型三通球阀适用于介质的分流、合流或流向切换,T型孔道可以使三个通道互相连通或使其中两个通道连通,三通球阀一般采用两个阀座结构,亦可根据用户要求采用四阀座结构。
