DTAS/DTBS气动Y型疏水阀是本公司根据热电厂设备疏水而专业开发设计生产的新一代蒸汽疏水阀，该产品接近直线的流通设计，减小流阻，二次节流原理，减小冲蚀，提高寿命。阀芯、阀座采用整体硬质合金，关闭内漏≤VI级，可拆卸中腔密封设计，杜绝外漏，检修方便等特点，还可在易燃，易爆场合使用，根据控制系统或调节仪表的信号，切断或开启阀门，从而实现对被控参数的使用要求。因此它广泛应用于火电厂等行业的远程控制。

    本型产品由正作用和反作用之分，其公称通径等级DN（mm）由20~100;公称压力等级PN由150Lb(2.0MPa), 300Lb(5.0MPa), 600Lb(10MPa),900Lb(15MPa)等多个等级之分;气源压力0.14~0.4(MPa);信号范围Pr(KPa)20~100,40~200;泄漏量几乎近似于0泄漏，该产品的有多种规格可供选择

    本系列疏水阀机构新颖,功能完善、品种齐全。
DTAS/DTBS气动Y型疏水阀类型
    ：
    该阀门由新系列气动薄膜执行机构和Y 型疏水阀二部分级成（图1）Y 型疏水阀是具有特殊结构的调节阀体二端为焊接式，适用于特定的配管。
    执行机构有正、反二种作用形式：
    当信号压力增加，推杆伸出膜室的叫正作用，与阀配合构成气关式。当信号压力增加，推杆退入膜室的叫反作用，与阀配合构成气开式。
其原理：
    当信号压力输入膜室后，在膜片上产生推力，压缩弹簧，使推杆移动，带动阀杆，改变阀芯与阀座之间流通面积，直到弹簧的反作用力与信号压力作用在膜片上的推力相平衡，从而达到自动调节工艺参数的目的。
