水封闸阀
相关型号：DS/Z64H,Z61H-10C,Z61H-100C,Z61H-25C,Z61H-32C,Z61H-64C
主要结构特点及用途：
Chief strucure features and usages：
1.本产品的阀盖填料室具有水密封结构，当接口通人压力为061MP的水时，可使系统与大气隔离，保证系统具有良好的气密性
2.S/Z型系列采用双闸板双向弹性密封、启闭灵活、迅速、密封可靠。
3.产品结构简单、紧凑合理、检修方便、使用寿命长
4.在管路上作启闭装置用，必须处于全开或全闭状态，不得用于调节流量
5.阀们连接方式有法兰和焊接两种，驱动方式为手动和电动
6.S系列水封阀门适用于公称压力100MPa，工作温度425℃，工作介质为水、蒸汽、油品和非腐蚀气体的管路上作启闭装置用，尤其适用于火电厂汽机真空冷凝系统
1.The chamber of packing of the valve\'s bonnet is of a water-sealed structure,which,when the water of 0.6-1MPa pressure goes into the mouthpiec,can make the system isolated from air to ensure the system with a good leak proofness
2.Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and fast to open and close,reliable sesling
3.Simple,compact and reaso able structur,easy to overhaul and long duration
4.When to be used as the open&close device on pipelines,it must be in fully-opened or fully-closed state and unallowed to be used for flow adjustment
5.Two ways of connection:by flange and welding,two driving ways:manually and electrically
6.Suitable to act as the open & close device for the pipelines with the working medium of water,steam,oil goods and non-corrosive gas,especially for the vacuum condensation system of the steam tufbine in steam power palnts.
